Hey, PG&E! Energy Storage is Not the Same as Energy Generation!!

Peter Lobner, updated 20 February 2022

The two-unit Diablo Canyon nuclear power plant, which is owned and operated by Pacific Gas & Electric (PG&E), is the last operating nuclear power station in California. In the five year period from 2016 – 2020, the average annual load factor performance of these power plants was as follows:

  • Diablo Canyon 1:  1,138 MWe net @ 91.56% = 1.042 Gigawatt-years (GW-years) generated per year
  • Diablo Canyon 2:  1,118 MWe net @ 85.64% = 0.957 GW-years generated per year

Over that five year period, the average annual amount of electricity delivered to the California electrical grid by the two-unit Diablo Canyon nuclear power plant was about 2.0 GW-years (2,000 Megawatt-years or 17,520,000 Megawatt-hours). On a daily basis, that’s an average of about 48,000 MW-hours. This electricity was generated reliably, 24/7 (except during planned outages), with zero carbon emissions.

In 2016, I reported (https://lynceans.org/all-posts/the-nuclear-renaissance-is-over-in-the-u-s/):

“On 21 June 2016, PG&E issued a press release announcing that they will withdraw their application to the NRC for a 20-year license extension for the Diablo Canyon 1 & 2 nuclear power plants and will close these plants by 2025 when their current operating licenses expire.  PGE will walk away from about 41 GW-years of carbon-free electric power generation.”

The shutdown plan was approved by the California Public Utilities Commission in January 2018.

In 2019, PG&E reported that their mix of generation sources (owned and purchased from a third-party) looked like this:

A few interesting points about this PG&E generation source chart:

  • Nuclear power generation is the biggest piece of the pie chart. Shutdown of Diablo Canyon by 2025 will eliminate this piece.
  • Renewables include wind, solar, small hydro, geothermal and biomass / waste.  Batteries are not included because they are energy storage devices, not energy generation sources.  The energy stored in a grid-scale battery comes from a generator, or simply, from the grid.
  • Large hydro depends on the associated reservoirs having enough water in them. The Edward Hyatt hydroelectric power plant at Lake Oroville (California’s second-largest reservoir) was shut down in August 2021 for the first time since it opened in 1967 because of low water levels during the persistent drought affecting the US West. Power production at Oroville resumed in January 2022 with only a single hydroelectric generator, after heavy winter precipitation increased lake water level. If the drought continues, the large hydro piece of the pie chart will shrink.

Another point is that the PG&E generation source mix is quite different from the California state-wide generation source mix reported by the California Energy Commission in 2020 and shown in the following pie chart.  Not all of the generation sources represented in this chart are physically located in California (more on that later).

Diablo Canyon has a disproportionate impact on the PG&E  generation mix because they own the nuclear power plant and they take credit for its entire net generation.  State-wide, nuclear power makes up only 9.33% of the state generation mix in a much larger electric power market.

When Diablo Canyon is shut down in 2025, I would think that the PG&E energy generation mix will look a lot more like the California state-wide generation mix, with most of the nuclear power generation share being replaced, at least in the short term, by fossil fuel-powered generators.

In January 2022, PG&E announced that they have a plan: “PG&E Corp. said it has reached agreements to install nine new battery energy storage projects as part of a push to replace a retiring nuclear power plant and help decarbonize California’s power grid.”

So, let me see if I’ve got this right.  PG&E is going to use grid-scale storage batteries that produces zero carbon emissions during their operation to partially replace a nuclear power generating station that produces zero carbon emissions during 24/7 operation. Where will the power come from to charge those batteries?  It’ll come from the California Independent System Operator (CAISO) grid, which has the California state-wide generation source mix shown above, with almost 40% coming from fossil fuel-powered generators in 2020, and likely to increase after Diablo Canyon’s retirement. So, one charge-discharge cycle of a grid-scale battery isn’t carbon-free.

PG&E further announced, “The proposed projects would have a total capacity of about 1,600 megawatts, which would bring its total battery energy storage capacity to more than 3,300 gigawatts by 2024…”

On the surface, that sounds like an impressive amount of battery capacity, but let’s put it in perspective.

The former Moss Landing fossil power station on Monterey Bay was decommissioned and transformed into a grid-scale energy storage facility. In August 2021, after completing Phase II of the transformation, the facility was operating with a capacity of 400 MW / 1,600 MW-hours, making it the world’s largest grid-storage project. The facility’s owner, Vistra Energy, said the Moss Landing facility could be expanded to a capacity of up to 1,600 MW / 6,000 MWh.

At its current discharge capacity of 400 MW, the Moss Landing batteries could discharge their full energy storage capacity of 1,600 MW-hours in about four hours.  Then the battery is “empty” and needs to be recharged from the CAISO grid (as we discussed, that’s about 40% from fossil-powered generation sources in 2020). Of course, a grid-storage facility wouldn’t be operated regularly on such a stressful cycle. But my point is that the world’s largest grid-storage project is be capable of delivering no more than 3.3% of the 48,000 MW-hours of electricity delivered daily, 24/7, with zero carbon emissions, by the Diablo Canyon nuclear power plant.

California has a huge, and growing, energy problem of its own making. With Diablo Canyon and several fossil-powered generators scheduled for retirement in the next few years, the state needs new generating capacity.  However, the development time scale for a new large generating facility in California, especially considering the state’s challenging regulatory environment, might have to be measured in decades.

One of California’s solutions to its shortfall of electrical generating capacity is to import electric power from other states and nations.  The U.S. Energy Information Administration (EIA) reported that California was the largest net electricity importer, by a wide margin, of any state in 2019. Its net electricity imports were 70.8 million MW-hours, or 25% of the state’s total electricity usage. California utilities partly own and import power from several power plants in Arizona and Utah. In addition, California’s electricity imports include hydroelectric power from the Pacific Northwest and power from fossil and wind generators in Mexico.

Source: EIA

Grid-scale battery storage is not going to solve the state’s shortfall of electrical generating capacity. Rather, the batteries are a means to mitigate short-term demand peaks and help stabilize the grid as generators attempt to match energy supply with demand.

Another mitigating measure used by CAISO is a “flex alert,” which asks consumers to cut back on electricity usage and move their electricity usage to off-peak hours, typically after 9 pm.  CAISO issued five flex alerts in 2020 and eight in 2021. When a grid-scale battery is discharged during a flex alert, recharging it would add a large load on an already strained grid; probably not a good idea.

California is throwing away valuable 24/7 generating capacity and replacing it with intermittent renewable generators, with grid-scale energy storage facilities to provide short-term mitigation that doesn’t address the real underlying problem.  There is no substitute for adequate generating capacity, sized to meet the current and future demands of businesses and individuals as we try to move together into a more electrified future.

Failing that, I can see increasing electric power rates, more flex alerts, and in California, I wouldn’t be surprised to see some form of legislated energy rationing coupled with higher energy use taxation. So much for that vision of a more electrified future.

Don’t sell you gasoline or diesel-powered car yet.  You may need it during the next flex alert.

20 February 2022 update: Moss Landing battery fires

Since becoming operational, Vistra Energy’s Moss Landing battery storage facility on Monterey Bay experienced two damaging fire events in lithium-ion battery packs. A fire on 4 September 2021 set off fire suppression system sprinklers that damaged about 7,000 batteries. Vistra Energy reported corrective actions following this fire on 21 January 2022.  Another fire on 13 February 2022 resulted in 10 melted lithium-ion battery packs. The latest fire event was contained by the facility’s fire suppression system. Vistra reported that it was looking further into the latest incident, while the Moss Landing facility remains offline during the investigation.

Veteran LSR Car Little Giant Raises the US National Electric Car Speed Record

Peter Lobner, 2 November 2021

In 2016, I wrote about Ohio State University’s Venturi Buckeye Bullet-3 (VBB-3) all-electric, four wheel drive land speed record (LSR) car, which set an FIA (Federation Internationale de l’Automobile) world electric vehicle two-way land-speed record (Category A Group VIII Class 8) at an average speed of 341.4 mph (549 kph) on 19 September 2016. (https://lynceans.org/all-posts/vbb-3-the-worlds-most-powerful-electric-car-will-challenge-the-land-speed-record-in-2016/)

That FIA two-way world speed record still stands, but on 1 October 2021, the Team Vesco 444 reVolt Systems streamliner, Little Giant, set a faster US national electric vehicle Class E3 record at 353.870 mph (569.499 kph) driven by Eric Ritter.  This is a US national record because the team was not able to recharge to Little Giant’s batteries fast enough to enable it to make the return runs within the 60 minute time limit set by the FIA for world records. The highest recorded speed of the Little Giant on the four runs was 357.0 mph (574.5 kph).

Little Giant is a veteran streamliner that made its debut at the 1957 Bonneville Speed Week, where it reached a speed of 169 mph and received the “Best Engineered Car of the Year” award.  Over the years, it has been rebuilt several times.  Through 2020, Little Giant was powered by a variety of piston engines.

Well done to the Team Vesco 444 reVolt Systems efforts to raise the electric car land speed record!

First-ever Lower Colorado River Basin Water Shortage Declaration

Peter Lobner, updated 17 September 2011

At its maximum capacity, Lake Mead water level is at an elevation of 1,220 feet (372 meters) at the Hoover Dam and holds 9.3 trillion gallons (36 trillion liters) of water. It was last at its maximum capacity in 2000 and has been declining since then as shown in the following graph.

Source: Universe Today, data via US Bureau of Reclamation & NASA

In my 18 June 2021 post, I discussed the Lake Mead water supply for Las Vegas and the alarming trend of decreasing water level in Lake Mead as a result of the persistent drought in the watershed for the Colorado River. 

In July, the Bureau of Reclamation began releasing additional water from reservoirs upstream of Lake Powell (which is upstream of Lake Mead) in an attempt to stabilize the lake level and maintain hydropower generation at the Glen Canyon dam (which forms Lake Powell). 

The following chart shows that the Lake Mead water level was at 1,067.72 feet on 17 August 2021, more than seven feet below the 1,075 foot threshold for triggering a water shortage declaration.  The lake level appears to have temporarily stabilized, possibly benefiting from the increased releases into upstream Lake Powell.

Source: Universe Today, data via US Bureau of Reclamation & NASA

On 16 August 2021, the Bureau of Reclamation issued their much anticipated projection of 2022 operating conditions for Lake Powell and Lake Mead. They reported: 

“Given ongoing historic drought and low runoff conditions in the Colorado River Basin, downstream releases from Glen Canyon Dam and Hoover Dam will be reduced in 2022 due to declining reservoir levels. In the Lower Basin the reductions represent the first “shortage” declaration—demonstrating the severity of the drought and low reservoir conditions.”

The planned actions in response to this first-ever shortage declaration take effect on 1 January 2022, as described in the Bureau’s news release here: https://www.usbr.gov/newsroom/#/news-release/3950

In summary, the following cuts in Colorado River water allocations are expected:

  • Arizona:  Loses 18% of the state’s annual apportionment
  • Nevada:  Loses 7% of the state’s annual apportionment
  • Mexico:  Loses about 5% of the country’s annual allotment

California has more senior water rights than Arizona and Nevada and will be spared immediate cutbacks when they are implemented on 1 January 2022.

Additional cuts in water allocations will be triggered if Lake Mead water level continues to decline to the following thresholds:  1,050 feet, 1,045 feet, and 1,025 feet.

Let’s pray for a lot of wet weather in the US southwest.

Could Nuclear-Powered Crypto Currency Mining Become a Trend?

Peter Lobner, updated 8 March 2024

The term “bitcoin mining” has become a colloquial expression, but the actual activity involved in mining a crypto currency isn’t intuitively obvious to the casual observer. Marcus Lu, reporting for Visual Capitalist, can help us out here.  He explained:

“When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash. Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world. These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.”

So your basic crypto currency miner needs a lot of computer processing power, electric power and an internet service provider.  To get started, all of that requires some hard currency, unless you can find a work-around. Now, a few recent headlines make a bit more sense:

  • “1,069 Bitcoin Miners Steamrolled In Malaysia for Stealing Energy,” 17 July 2021
  • “Illegal Crypto Mining Farm With Almost 5,000 Computers Busted in Ukraine – The illegal operation cost between $186,000 and $259,300 in electricity to the state each month.” 12 July 2021
  • “Police find bitcoin mine using stolen electricity in West Midlands (UK),” 28 May 2021
  • “U.S. small towns take on energy-guzzling bitcoin miners,” 13 May 2021
  • “Cryptocurrency miners grapple with major energy crunch in Kazakhstan,” 27 November 2021

These headlines suggest that crypto currency mining can generate significant wealth, and, for some, this prospect is worth the risk of being caught stealing a lot of electricity.  

Sam Ling, writing for Miner Daily in May 2021, describes his methodology for estimating the cost to mine a bitcoin, which depends on many factors, including the cost of electricity and the cost, processing power and lifetime of the computers.  Ling estimates: “It currently costs between $7,000-$11,000 USD to mine a bitcoin. …… As the price of BTC is $56,000, it remains very profitable to mine bitcoin.” You’ll find more details here: https://minerdaily.com/2021/how-much-does-it-cost-to-mine-a-bitcoin-update-may-2021/

Of course, there are many legitimate businesses mining bitcoins.  You’ll find a list of the top bitcoin mining firms here: https://www.ventureradar.com/keyword/Bitcoin%20Mining

At the industrial-size end of the crypto mining facility spectrum, US power company Talen Energy announced in July 2021 that it is planning to develop a nuclear-powered crypto mining facility and data center adjacent to its two unit, 2,494 MWe Susquehanna Steam Electric Station in Pennsylvania. The first phase of the crypto mining facility will require 164 MW of power and is due to come online in Q2 2022. When complete, the crypto mining facility will require 300 MW of on-site power supplied from the nuclear power plants via two independent substations.  The potential exists to expand the crypto mining facility to 1,000 MW capacity in the future.

In May 2021, Nic Carter reported in the Harvard Business Review, “According to the Cambridge Center for Alternative Finance (CCAF), Bitcoin currently consumes around 110 Terawatt-Hours per year — 0.55% of global electricity production, or roughly equivalent to the annual energy draw of small countries like Malaysia or Sweden.”  That would put current global crypto currency mining energy consumption at about 30th place among all nations in the world.  In the future, energy consumption for crypto currency mining is certain to increase, perhaps dramatically.  Is there an upper limit?

The current trend in tracked by Digiconomist with their Bitcoin Energy Consumption Index, which provides the latest estimate of the total energy consumption of the Bitcoin network. The following chart is from their website here:  https://digiconomist.net/bitcoin-energy-consumption/

While the Susquehanna Steam Electric Station is fortunate to have a gained a new customer for their electric power, Exelon Generation reported in June 2021 that three of its Illinois nuclear power plants, Byron, Dresden, and Quad Cities, did not clear the PJM Interconnection capacity auction. This means that these Exelon nuclear plants have lost a customer for their future electric power generation. The issue is complex, but appears to be rooted in power auction rules that are, at least in part, inconsistent with the nation’s goal of reducing the overall carbon footprint of electric power generation. Exelon explained:

“Byron and Dresden, despite being efficient and reliable units, face revenue shortfalls in the hundreds of millions of dollars because of declining energy prices and market rules that allow fossil fuel plants to underbid clean resources in the PJM Interconnection capacity auction.”

In mid-September 2021, Illinois Gov. J.B. Pritzker signed an energy bill (Senate Bill 2408) that included provisions for Exelon to receive the financial incentives it needed to keep the Byron and Dresden nuclear plants open.  Exelon subsequently confirmed that the plants will continue operating for at least six more years (thru 2027).

Exelon is not the only US nuclear power utility with this type of issue. Several more US nuclear power plants are at risk of retiring prematurely instead of seeking a license extension to operate for another 20 years generating zero-carbon electricity.  S&P Global Platts provides a good overview of the seriousness of the current situation in the following infographic:

Source: S&P Global Platts, 3 May 2021

Congress and the state governments need to act now to protect the nuclear power plants at high risk of premature closure, and ensure their continued operation as generators of zero-carbon electricity.

Perhaps the planned Talen Energy crypto currency mining venture points to an odd synergism between miners and nuclear power plant operators. Instead of retiring nuclear power plants that are struggling financially, it may make sense to the owners to build crypto mining facilities and reap the profits from crypto currency sales. Taken to its extreme, you can imagine a nuclear power plant diverting all of its zero-carbon electric power output to its own very profitable crypto mining facility. Just imagine how many Bitcoins could be generated by diverting all US nuclear power plant electricity generation (about 20% of total US electricity generation) to power crypto currency miners. 

Going back to my question “Is there an upper limit?,” I’m afraid only time will tell.

Talen Energy’s bitcoin mining adventure was not successful. In May 2022, the firm filed for Chapter 11 bankruptcy in connection with a financial restructuring of the firm. After exiting bankruptcy in 2023, the firm sought to sell its Susquehanna data center as a means to pay off debts and generally improve its cash flow. On 4 March 2024, Talen Energy announced the sale of its Susquehanna data center campus for $650 million to cloud service provider Amazon Web Services (AWS). By virtue of its existing Power Purchase Agreement (PPA) with Susquehanna, Talen Energy remains as an energy retailer, positioned between the Susquehanna nuclear power plant and the AWS-owned data center. Talen will providing fixed-price electricity to the AWS data center, which has a contractual commitment to ramp up its power demand as the data center is expanded over several years. AWS has a one-time option to cap its power demand at 480 MW. Talen will be able to supply up to 960 MW of power under the terms of its PPA with Susquehanna.

On the Threshold of a Dream

Peter Lobner, Updated 29 September 2021

That’s the title of my favorite Moody Blues album.  It’s also the current status of commercial civilian access to space.  

The leading contenders are Richard Branson, with his firm Virgin Galactic Holdings, Inc., and Jeff Bezos, with his firm Blue Origin. 2021 is the year both firms plan to make their first commercial civilian sub-orbital flights with paying customers.  

On 25 June 2021, the Federal Aviation Administration (FAA) granted approval of Virgin Galactic’s full commercial space-launch license.  The FAA also is reviewing Blue Origin’s commercial space-launch license application, and final approval is expected soon. For commercial spaceflight, the FAA’s primary regulatory role is to ensure that the spaceflight activity is not a hazard to the general public or other aviation activities. The FAA does not regulate the design and operating characteristics of the spacecraft, as it does for commercial aircraft.  Passengers flying on commercial spacecraft must acknowledge the risk by signing a waiver….and people are lining up and will be paying hefty sums to become civilian astronauts.

Virgin Galactic

Virgin Galactic successfully completed its third manned test flight of the Spaceship II on 22 May 2021, with VSS Unity flying for the first time from New Mexico’s Spaceport America, which is located in the high desert near the small town of Truth-or-Consequences. I visited Spaceport America in 2015 when it was a complete but very quiet place, with only a Spaceship II mockup.  That has all changed in 2021 as Virgin Galactic completed its testing program and is now preparing for its first commercial flights.

Virgin Galactic will be flying its two Spaceship II vehicles, VSS Unity and VSS Enterprise, from its base at Spaceport America.  Virgin announced that the next sub-orbital flight is scheduled to occur on 11 July 2021 and Richard Branson is expected to be among the six people on board, all Virgin employees.

Virgin Galactic’s long-range plan is to operate 400 flights per year, per spaceport.   To achieve this goal, Virgin recently completed the first of its next generation Spaceship III vehicles, VSS Imagine, and has started manufacturing the next Spaceship III, VSS Inspire.

Blue Origin

Blue Origin’s New Shepard spacecraft is named for US astronaut Alan Shepard, who made the first US sub-orbital flight on 5 May 1961 on the Mercury-Redstone 3 mission and became the second man in space (after Russian astronaut Yuri Gagarin). To date, Blue Origin has made 15 consecutive unmanned launches with successful crew capsule landings, plus a successful pad escape test in 2012.

Contingent on receiving FAA license approval, Blue Origin announced that it has scheduled its first manned flight on 20 July 2021 from its west Texas launch facility near the town of Van Horn.  This is the 52nd anniversary of the Apollo 11 moon landing. The four passengers for the first New Shepard manned sub-orbital flight will be Jeff Bezos, his brother Mark, Wally Funk (who is the last surviving member of NASA’s 13 female astronaut candidates for Project Mercury in the 1960s), and a fourth (as yet unnamed) passenger who won an auction by bidding $28 million for the last passenger seat.    That amount will be donated to Blue Origin’s foundation, Club for the Future, to inspire future generations to pursue careers in STEM and help invent the future of life in space.

Update 3 Sep 2021: The threshold has been crossed

Congratulations to Virgin Galactic and Blue Origin for their first successful suborbital passenger flights.

On 11 July 2021, the Virgin Galactic flight named Unity 22 took off from Spaceport America with pilots Dave Mackay and Mike Masucci and four passengers: Richard Branson, Beth Moses (Virgin Galactic’s chief astronaut instructor), Sirisha Bandla (VP of government affairs), and Colin Bennett (lead operations engineer). The flight reached a peak altitude of 282,000 feet (53.5 miles / 86.1 kilometers) and flew back for a landing on the runway at Spaceport America.

Virgin Galactic says that it already has more than 600 reservations at a “ticket” price of $250,000 apiece.  Expensive?  Yes, but such a trip was impossible to do even a year ago.  Regular passenger flights are expected to start in 2022. What will the price for this type of trip into space be in a decade?  Probably still pretty expensive, but this is just a first step in democratizing space.

On 20 July 2021, the FAA Office of Commercial Space Transportation issued an order revising their criteria for its FAA Commercial Space Astronaut Wings Program.  SpaceNews reported: “According to the order, the FAA will award wings to commercial launch crew members who meet the requirements in federal regulations for crew qualifications and training, and fly on an FAA-licensed or permitted launch to an altitude of at least 50 miles (80 kilometers). The order also requires those crew members to have demonstrated ‘activities during flight that were essential to public safety, or contributed to human space flight safety.’ The last provision is new in the order.”  

Commercial Space Astronaut Wings previously were awarded to Dave Mackay, Mike Masucci and Beth Moses for their roles as crew during flight testing of Spaceship II. The first commercial astronaut wings were awarded in 2004 to Virgin Galactic pilots for Spaceship I, Mike Melvill and Brian Binnie.

The FAA approved Blue Origin’s flight on 12 July, one week before the 20 July 2021 launch date.  The autonomous New Shepard vehicle does not have a pilot or crew.  The 20 July flight carried four passengers: company founder Jeff Bezos, his brother Mark, former astronaut candidate Wally Funk and Oliver Daemen. The flight reached a maximum altitude of 351,000 ft (66.5 miles / 107 kilometers), above the Kármán Line at 62 miles / 100 kilometers above mean sea level. None will likely meet the updated FAA criteria for commercial astronaut wings.

I’m looking forward to a day when suborbital flights are commonplace and orbital tourism is becoming a reality.  This day is not far away.

Update 29 Sep 2021: Virgin Galactic cleared to resume flights

Virgin Galactic reported: “The FAA today advised Virgin Galactic that the corrective actions proposed by the Company have been accepted and conclude the FAA inquiry, which began August 11, 2021. They include:

  • Updated calculations to expand the protected airspace for future flights. Designating a larger area will ensure that Virgin Galactic has ample protected airspace for a variety of possible flight trajectories during spaceflight missions.
  • Additional steps into the Company’s flight procedures to ensure real-time mission notifications to FAA Air Traffic Control.”

Best wishes to Virgin Galactic and Blue Origin as they continue to develop their paths for private access to space.

Las Vegas Made a Good Bet on the Third Straw

Peter Lobner

Las Vegas relies on Lake Mead for 90% of its water needs. Currently, water from Lake Mead can be supplied to Las Vegas by three intakes at different levels in the lake.  The newest, and deepest, is known as the “third straw” intake (IPS-3), which taps into the lake at 860 feet above sea level. That’s 190 feet below the highest existing intake, IPS-1, at 1,050 feet.

The operation of this three-intake system is explained in Southern Nevada Water Authority’s (SNWA) short video, “How does the SNWA’s Low Lake Level Pumping Station protect our drinking water supply?” at the following link: https://www.youtube.com/watch?v=bDDuid6XJnw&t=39s

You’ll find Lake Mead current water level and historical water level data here:  http://mead.uslakes.info/level.asp

On 18 June 2021, the lake level was 1,070.43 feet MSL at 5:00 PM.  This is 158.57 feet below the “full pool” level of 1,229.00 feet and is only 20.43 feet above the highest (IPS-1) intake.

Source: http://mead.uslakes.info/level.asp

On 10 June 2021, Lake Mead water level was 1,071.51 at 7:00 AM and was about 36% full.  The lake had not been this low since July 2016.  Using just the 10 June and 18 June data points, lake water level currently is decreasing at about 1.5 inches per day.

Runoff from the Rocky Mountain snowpack is essentially over this year, so water level is expected to continue declining until the start of the next rainy season in November.

The first-ever official federal water shortage declaration is expected in August 2021, when the Bureau of Reclamation issues its regularly scheduled long-term water level projection.  A Level 1 declaration would be implemented in January 2022 under agreements negotiated with seven states that rely on Colorado River water: Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming. Water from the Colorado River serves 40 million people in these states and Mexico.

Let’s pray for a lot of wet weather in the US southwest.

What Do a Tidal Turbine and an Airship Have in Common?

Orbital Marine Power (https://orbitalmarine.com) is developing a large, moored tidal turbine, the O2, which they claim is the most powerful tidal turbine in the world. The O2 soon will be deployed at sea off the Orkney Islands, northeast of Scotland.

Key features of the O2 tidal turbine are:

  • 74 meter (243 ft) tubular steel hull with fore and aft mooring connections.
  • Hydraulically-actuated steel legs extending from the hull support the generator nacelles and rotors that are deployed underwater after the hull has been moored using a four-point mooring system.
  • Two 20 meter (65.6 ft) diameter, 2-bladed rotors give the O2 more than 600 m2 (6,458 ft2) of swept area to capture flowing tidal energy.
  • Blade pitch control enables bi-directional operation of the turbines with the hull in a fixed moored position (the hull doesn’t swing with the tide).
  • Each rotor drives a 1 MWe generator housed in the nacelle.
  • Power is delivered to shore by a submarine cable.

Here are three short videos that will give you a quick introduction to this remarkable machine:

If the O2 demonstration proves to be successful, Orbital Marine Power plans to develop and deploy larger tidal turbines in the future.

So, what does the O2 tidal turbine have in common with an airship?  The Aeromodeller II airship design developed by Belgian engineer Lieven Standaert implements an airborne mooring as a means to generate power using two wind turbines while remaining aloft.

Both the O2 tidal turbine and the Aeromodeller II airship are buoyant vehicles in their respective media (water and air, respectively) and both are designed to extract power from that medium while moored (or tethered).  Important differences are that the O2 tidal turbine is permanently moored and supplies power to users on land.  The Aeromodeller II drops its anchor periodically to recharge its own power system while tethered and then raises its anchor to continue its journey.

The Bloodhound LSR Car is Biding its Time While on Display at the Coventry Transport Museum

Peter Lobner

I’ve reported previously on the Bloodhound LSR (land speed record) car in 2015, 2017, and lastly in 2019 when driver Andy Green made a series of high-speed test runs on the Hakskeen Pan in the Kalahari Desert in South Africa. On 17 November 2019, he achieved a top speed run at 628 mph (1,010 kph). The primary goal of the 2019 test campaign was to validate vehicle design and operation during high-speed runs up to 621 mph (1,000 kph).  To that, the team responded, “Mission accomplished.” You can read my post on the Bloodhound LSR’s 2019 campaign here:  https://lynceans.org/all-posts/land-speed-record-lows-and-highs-in-2019/

The 2019 test runs also were intended to provide an opportunity to fine-tune Bloodhound LSR before attempting a world land speed record run in 2020.  However, lack of funds in 2020 deferred installing the Nammo rocket engine needed for the land speed record attempt.  The worldwide COVID pandemic further intervened, cancelling a record attempt in 2020 and 2021.

The owner, Ian Warhurst, who had previously rescued the Bloodhound LSR from insolvency and then funded the 2019 high-speed tests, put the vehicle up for sale in January 2021.  On 17 May 2021, the Bloodhound LSR team and the Coventry Transport Museum in Coventry, UK, announced the Bloodhound LSR jet car had moved into a new home in the museum where it is now on public display as part of the Biffa Award Land Speed Record Exhibition.

The Bloodhound LSR team reported, “….the sponsorship team are busy raising the funding required to attempt a new world land speed record, with a speed above 800mph. Once the required funding and investment has been raised, Bloodhound will leave the museum and be prepared for the record-breaking campaign.”

In the Biffa Award Land Speed Record Exhibition at the Coventry Transport Museum, Bloodhound LSR joins two UK world land speed record holders: Thrust2 and ThrustSSC.

On 4 October 1983, Richard Noble drove the Thrust2 to a world land speed record two-way average speed of 633.468 mph (1,019.468 kph) in the Black Rock Desert in Nevada, USA.

On 15 October 1997, Andy Green drove the ThrustSSC to a new land speed record and broke the sound barrier with a speed of 763mph (Mach 1.020, 1,228 kph) in the Black Rock Desert. This occurred 50 years after Captain “Chuck” Yeager, flying the Bell X-1 rocket-powered aircraft, made the first supersonic flight on 14 October 1947.

Floating Nuclear Power Plants Will be Operating at Several Sites Around the World by the End of the 2020s

Peter Lobner

1. Introduction

This post is an update and supplement to the information on floating nuclear power plants (FNPPs) in my July 2018 post, “Marine Nuclear Power: 1939 – 2018,” at the following link: https://lynceans.org/all-posts/marine-nuclear-power-1939-2018/

An FNPP is a transportable barge housing one or more nuclear power reactors that can deliver electric power and other services, such as low temperature process heat and/or desalinated water, to users at a wide variety of coastal or offshore sites. FNPPs are a zero-carbon energy solution that has particular value in remote locations where the lack of adequate electrical power and other basic services are factors limiting development and/or the quality of life.

After being manufactured in a shipyard, the completed FNPP is fueled, tested and then towed to the selected site, where a safe mooring provides the interfaces to connect to the local / regional electrical grid and other user facilities.

The US operated the first FNPP, Sturgis, in the Panama Canal from 1968 to 1975.  Sturgiswas equipped with a 45 MWt / 10 MWe Martin Marietta MH-1A pressurized water reactor (PWR) that was developed under the Army Nuclear Power Program.

Sturgis supplied electric power to the Panama Canal Zone grid, replacing the output of Gatun Hydroelectric Plant. This allowed more water from Gatun Lake to be available to fill canal locks, enabling 2,500 more ships per year to pass through the canal. After decommissioning, dismantling was finally completed in 2019.

2. Akademik Lomonosov – The first modern FNPP

It wasn’t until 2019 that another FNPP, Russia’s Akademik Lomonosov, supplied power to a terrestrial electricity grid, 44 years after Sturgis.  The Lomonosov is a one-of-a-kind, modern FNPP designed for operation in the Arctic.  With two KLT-40S PWRs, Lomonosov supplies up to 70 MWe of electric power to the isolated Chukotka regional power grid or up to 50 Gcal/h of low temperature process heat at reduced electrical output to users in the industrial city of Pevek, near the eastern end of Russia’s Northern Sea Route.

Lomonosov started providing electricity to the grid on 19 December 2019 and regular commercial operation began on 22 May 2020.

3. FNPPs under development by several nations

Several nations are developing new FNPP designs along with plans for their serial production for domestic and/or export sale.  The leading contenders are presented in the following chart. 

Floating Nuclear Power Plants in Operation & Under Development

Akademik Lomonosov and the first four new FNPP designs in the above chart use small PWRs in various compact configurations. PWRs have been the dominant type of power reactor worldwide since their introduction in naval reactors and commercial power reactors in the 1950s. The Seaborg power barges will use compact molten salt reactors (CMSRs) that have functional similarities to the Molten Salt Reactor Experiment (MSRE) that was tested in the US in the early 1960s.

Russia

Russia is developing their 2nd-generation “optimized floating power unit” (OPEB) to deliver 100 MWe electric power, low temperature process heat and water desalination to support their domestic economic development in the Arctic. In November 2020, Rosatom director for development and international business, Kirill Komarov, reported that there was demand for FNPPs along the entire length of Russia’s Northern Sea Route, where a large number of projects are being planned. This was reinforced in May 2021, when Russia’s President Vladimir Putin endorsed a plan to deploy OPEBs to supply a new power line at Cape Nagloynyn, Chaunskaya Bay, to support the development of the Baimskaya copper project in Chukotka.  The development plan calls for 350 MWe of new generation from nuclear or liquid natural gas (LNG) generators.  Baimskaya currently is supplied from Pevek, where the Lomonosov is based.

A version of the OPEB also is intended for international export and has been designed with the flexibility to operate in hot regions of the world.  Bellona reported that “Rosatom has long claimed that unspecified governments in North Africa, the Middle East and Southeast Asia are interested in acquiring floating nuclear plants.”

China

In the 1960s, China Shipbuilding Industry Corporation (CSIC) set up the 719 Research Institute, also known as the Wuhan Second Ship Design Institute or CSIC 719, to develop applications for nuclear power technology in marine platforms. CSIC has become China’s biggest constructor of naval vessels, including nuclear submarines. 

About a decade ago, China considered importing FNPP technology from Russia.  In 2015, China’s National Development and Reform Commission (NDRC) agreed with a CSIC 719 design plan to develop an indigenous offshore marine nuclear power platform. This plan included both floating nuclear power plants and seabed-sited nuclear power plants. Today, part of this plan is being realized in the FNPP programs at China National Nuclear Corporation (CNNC) and China General Nuclear Power (CGN), two staunch competitors in China’s nuclear power business sector.

China included the development of CNNC’s 125 MWe ACP100S and CGN’s 65 MWe ACPR50S marine PWR plants in its 13th five-year plan for 2016 to 2020. The NDRC subsequently approved both marine reactor designs. 

As an example of the magnitude of China’s domestic offshore market for FNPPs, the total installed fossil fuel-powered generation in China’s offshore Bohai oilfield was estimated to be about 1,000 MWe in 2020 and growing.  Replacing just these generators and providing heating and desalination services for offshore facilities represents a near-term market for a dozen or more FNPPs.  Other domestic application include providing these same services at remote coastal sites and offshore islands. China has announced its intention to construct a batch 20 FNPPs for domestic use. The Nuclear Power Institute of China (NPIC) has recommended installing the country’s first FNPP at a coastal site on the Yellow Sea near Yantai, Shandong Province. South Korea raised its objection to this siting plan in 2019.

Other possible FNPP deployment sites may include contested islands that China has begun developing the South China Sea.  This is a very sensitive political issue that may partially account for why there has been very little recent news on the CNNC and CGN FNPP programs.  Based on their development plans discussed about five years ago, it seemed that China’s first FNPP would be completed in the early 2020s. 

In addition to their domestic applications, China has repeatedly expressed interest in selling their FNPPs to international customers.

South Korea & Denmark

In the absence of clear domestic FNPP markets in South Korea and Denmark, KEPCO E&C and Seaborg Technologies are focusing on the export market, primarily with developing nations.  

Details on modern FNPP designs 

You’ll find more details on these new FNPPs in my separate articles at the following links:

4. Maintaining FNPP fleets

All of the new FNPPs require regular reactor refueling and periodic maintenance overhauls during their long service lives.  The periodic overhauls ensure that the marine vessel, the reactor systems and ship’s systems remain in good condition for their planned service life, which could be 60 or more years.

The FNPPs with PWRs have refueling intervals ranging from about 2 years (ACP100S) to as long as 10 years (RITM-200). Some of the PWR refuelings will be conducted dockside, while others will be conducted in a shipyard during a periodic maintenance overhaul. For Russian FNPPs, such overhauls (referred to as “factory repairs”) are scheduled to occur at 12-year intervals for the Lomonosov and 20-year intervals for the OPEB.

The fundamentally different Seaborg CMSR, with molten salt fuel, is refueled regularly while the reactor is operating.  Periodic maintenance overhauls would still be expected to ensure the condition of the marine vessel, the reactor systems and ship’s systems.

With a fleet of FNPPs in service, most will be operating, while some are in the shipyard for their periodic maintenance overhauls.  In addition, new FNPPs would be entering service periodically. When it is time to service an FNPP in a shipyard, it will be replaced by a different (existing or new) FNPP that is brought in to take its place.

At the end of its service life, an FNPP will be returned to a shipyard to be decommissioned, decontaminated and then dismantled, like Sturgis. Russia already has established special long-term spent fuel and radioactive waste storage facilities in mainland Russia. China, South Korea and Denmark will need to make similar provisions for the end-of-life processing and safe disposition of their retired FNPPs.

5. Economic issues

In March 2019, Jim Green wrote on what he called “the questionable economics of SMRs” in his article, “An obituary for small modular reactors.” One of his conclusions was that, “…in truth there is no market for SMRs.”  Another conclusion was that “No-one wants to pay for SMRs. No company, utility, consortium or national government is seriously considering building the massive supply chain that is at the very essence of the concept of SMRs ‒ mass, modular factory construction. Yet without that supply chain, SMRs will be expensive curiosities.” 

I might agree that this could be the case for land-based SMRs, but marine FNPPs are a different matter.  In remote areas being considered for FNPP deployment, there probably are fewer energy options, energy price competition is a lesser concern, and an extended fuel supply chain is undesirable or impractical. Examples include FNPP applications supporting resource development along Russia’s Northern Sea Route and in China’s offshore waters.  The domestic markets in both nations probably can support production runs of 10s of FNPPs.  While this isn’t “mass production” in the sense of many heavy industries, it would certainly be a big enough production run to change the manufacturing paradigm in the marine nuclear industry and provide a real validation of the economics of SMRs.

6. International nuclear regulatory / legal / political issues

Deployment of the first modern FNPP, the Akademik Lomonosov, in the Arctic was accomplished under Russian domestic nuclear laws and regulations and, after the reactors were fueled, the transit to its destination was accomplished within Russian territorial waters. The final destination, Pevek, is about 980 km (609 miles) from the Bering Strait and the nearest international boundary.  Not without controversy, particularly among Scandinavian nations, Lomonosov’s deployment was straightforward after the vessel completed all stages of licensing and regulatory reviews required in Russia.  Now Lomonosov has been commissioned and is setting an example for the rest of the world by operating successfully in a remote Arctic port.

Except for Russia’s nuclear-powered icebreaking vessels, there have been no other civilian nuclear vessels in service since Japan’s Mutsu retired in 1992. For almost 30 years, there has been no need to establish and maintain a comprehensive international civilian nuclear vessel regulatory and legal framework. 

In her August 2020 article, “Legal framework for nuclear ships,” Iris Bjelica Vlajić reports that the main international documents regulating the use of civil nuclear ships are:

  • UN Convention on the Law of the Sea (UNCLOS)
  • IMO Convention for the Safety of Life at Sea (SOLAS)
  • IMO Convention on The Liability of Operators of Nuclear Ships and the Code of Safety for Nuclear Merchant Ships

Further FNPP deployment along Russia’s arctic coast and initial FNPP deployment in China’s territorial coastal waters can be accomplished under the respective nation’s domestic nuclear laws and regulations.  It’s easy to imagine that a range of international issues will arise as FNPP deployment becomes more widespread, in situations like the following

  • An FNPP is deployed to a site close to an international border.
  • An FNPP is deployed in a sensitive international ecosystem.
  • A fueled FNPP from any nation needs to transit an international strait or an exclusive economic zone (EEZ) of another nation enroute to its destination.
  • An FNPP is deployed to an island that is contested by one or more other nations (i.e., several islands and island groups in the South China Sea).

There has been speculation recently that the sensitivity of the last issue, above, may be contributing to increased secrecy in the last couple of years related to China’s FNPP programs.

As FNPP deployment expands, the international community will be playing catch-up as the UN, IMO, IAEA and others contribute to developing a modern nuclear regulatory and legal framework for FNPPs.

7. Conclusions

In the next decade, I think it’s very likely that two or more of the new FNPP designs will enter service.  The leading contenders seem to be Russia’s OPEB and China’s ACP100S FNPP.   It remains to be seen if economic issues and/or international nuclear regulatory / legal / political issues will stand in the way of eventual FNPP deployments to sites around the world.

The Sad Tale of New York’s “Greener Grid” and the Closure of Two Nuclear Power Plants

Peter Lobner, updated 29 July 2022

Goodbye Indian Point 2 and 3.  Your contributions of zero-carbon energy to New York’s “clean energy grid of the future” will be greatly missed.

In an average year, the 1,028-MWe Indian Point Unit 2 nuclear power plant and the 1,041-MWe Unit 3 operated at capacity factors of greater than 90% and delivered more than 18,000 GWh (thousand MWh) per year of zero-carbon electricity to the New York state electrical grid. Unit 2 was shutdown on 30 April 2020 and Unit 3 followed on 30 April 2021.  Prior to its final shutdown, Unit 3 had run continuously for 753 day, which set a new nuclear industry world record.  The ANS Newswire reported, “The plant’s closure is the result of a settlement agreement reached in 2017 by Entergy and the State of New York and environmental groups opposed to Indian Point’s operation. According to an April 28 (2021) news release from Entergy, its decision to accede to the shutdown was driven by a number of factors, including ‘sustained low current and projected wholesale energy prices that reduced revenues.’”

Now, Indian Point Units 2 and 3 are delivering exactly zero zero-carbon energy.  I imagine the environmental groups involved in the settlement agreement are hailing the shutdowns as great achievements.  I think the shutdowns represent remarkable shortsightedness (I’m using the kindest words I can think of) on the parts of Entergy and the State of New York.

New York Independent System Operator, Inc. (NYISO) operates the New York state electrical grid, which is divided into two main parts, “downstate”, which includes New York City and the Indian Point Units 2 and 3 nuclear power plants, and “upstate,” which includes the Nine Mile Point and Ginna nuclear power plants. I credit NYISO with providing the public with excellent reports that summarize their annual grid and electrical market performance.  In their Power Trends 2021 report, NYISO states: “The NYISO is committed to offering the tools, skills, independent perspectives, and experience necessary to transition to a zero-emission power system by 2040.” 

I’ll refer to two of those NYISO Power Trend reports to illustrate the impact of closing the Indian Point 2 and 3 nuclear power plants on progress toward New York’s “clean energy grid of the future.”  Using their own graphics, let’s take a look at how NYISO was doing in 2019 (with both Indian Point Unit 2 & 3 operating), 2020 (Unit 2 shutdown in April), and their projected performance in summer 2021 (after Unit 3 shutdown).

2021:  New York statewide (projected, summer): 25% zero-emission; Upstate: 67% zero-emission; Downstate: 2% zero-emission

Source: NYISO Power Trends 2021

Anyone who can draw a tend chart from 2019 to 2021 using the above three years of data and then extrapolate to the State’s goal of a zero-emission power system by 2040 can see that New York’s plans for its “clean energy grid of the future” have come off the rails.  The slope of the curve to get from where NYISO is today to the State’s 2040 goal has gotten a lot steeper, and that translates directly into the cost of achieving that goal.  Surely the New York ratepayers served by NYISO will pay the price in the years ahead as the State works to improve its zero-emission performance. Even getting back to where they were in 2019 would be a big improvement.

So, I reiterate that the Indian Point Unit 2 and 3 shutdowns represent remarkable shortsightedness on the parts of Entergy and the State of New York, both of which have undervalued two reliable sources of bulk zero-emission electric power generation, and have failed to appreciate Indian Point’s potential long-term contribution to achieving the State’s 2040 zero-emission power system goal (at a rate of more than 18,000 GWh per year).  New York State has failed to step up and provide economic incentives to enable Entergy to compete effectively against fossil fuel generators that have been benefiting for more than a decade from the low cost of natural gas fuel. In the wholesale market, the fossil generators can undercut nuclear generators and drive the cost of electricity down to levels that no longer support the continued operation of zero-emission nuclear power plants.  These trends can be seen in the following NYISO chart.

Source: NYISO Power Trends 2021

Beyond the significant loss of zero-carbon electrical generation capacity, the closure of a nuclear power plant will have significant local and statewide impacts through the loss of many full-time and temporary jobs, associated wages, and income and property taxes.  You’ll find a thorough discussion of these issues in the May 2021 ANS Nuclear Newswire article, “The consequences of closure: The local cost of shutting down a nuclear power plant,” at the following link: https://www.ans.org/news/article-2877/the-consequences-of-closure-the-local-cost-of-shutting-down-a-nuclear-power-plant/

R.I.P. Indian Point Units 2 and 3.

Update – 29 July 2022

In July 2022, the American Nuclear Society reported, “Stats show that closing Indian Point was a ‘mistake’ for New York.”  I’d say that’s putting it mildly.
