TVA urges conservation to limit rate impact

SM-1A Nuclear Plant Decommissioning details the US Army Corps of Engineers' removal of the Fort Greely reactor, Cold War facility dismantling, environmental monitoring, remote-site power history, and timeline to 2026 under a deactivated nuclear program.

Key Points

Army Corps plan to dismantle Fort Greely's SM-1A reactor and complete decommissioning of remaining systems by 2026.

✅ Built for remote Arctic radar support during the Cold War

✅ High costs beat diesel; program later deemed impractical

✅ Reactor parts removed; residuals monitored; removal by 2026

The US Army Corps of Engineers has begun decommissioning Alaska’s only nuclear power plant, SM-1A, which is located at Fort Greely, even as new US reactors continue to take shape nationwide. The $17m plant closed in 1972 after ten years of sporadic operation. It was out of commission from 1967 to 1969 for extensive repairs. Much of has already been dismantled and sent for disposal, and the rest, which is encased in concrete, is now to be removed.

The plant was built as part of an experimental programme to determine whether nuclear facilities, akin to next-generation nuclear concepts, could be built and operated at remote sites more cheaply than diesel-fuelled plants.

"The main approach was to reduce significant fuel-transportation costs by having a nuclear reactor that could operate for long terms, a concept echoed in the NuScale SMR safety evaluation process, with just one nuclear core," Brian Hearty said. Hearty manages the Army Corps of Engineers’ Deactivated Nuclear Power Plant Program.

He said the Army built SM-1A in 1962 hoping to provide power reliably at remote Arctic radar sites, where in similarly isolated regions today new US coal plants may still be considered, intended to detect incoming missiles from the Soviet Union at the height of the Cold War. He added that the programme worked but not as well as Pentagon officials had hoped. While SM-1A could be built and operated in a cold and remote location, its upfront costs were much higher than anticipated, and it costs more to maintain than a diesel power plant. Moreover, the programme became irrelevant because of advances in Soviet rocket science and the development of intercontinental ballistic missiles.

Hearty said the reactor was partially dismantled soon after it was shut down. “All of the fuel in the reactor core was removed and shipped back to the Atomic Energy Commission (AEC) for them to either reprocess or dispose of,” he noted. “The highly activated control and absorber rods were also removed and shipped back to the AEC.”

The SM-1A plant produced 1.8MWe and 20MWt, including steam, which was used to heat the post. Because that part of the system was still needed, Army officials removed most of the nuclear-power system and linked the heat and steam components to a diesel-fired boiler. However, several parts of the nuclear system remained, including the reactor pressure vessel and reactor coolant pumps. “Those were either kept in place, or they were cut off and laid down in the tall vapour-containment building there,” Hearty said. “And then they were grouted and concreted in place.” The Corps of Engineers wants to remove all that remains of the plant, but it is as yet unclear whether that will be feasible.

Meanwhile, monitoring for radioactivity around the facility shows that it remains at acceptable levels. “It would be safe to say there’s no threat to human health in the environment,” said Brenda Barber, project manager for the decommissioning. Work is still in its early stages and is due to be completed in 2026 at the earliest. Barber said the Corps awarded the $4.6m contract in December to a Virginia-based firm to develop a long-range plan for the project, similar in scope to large reactor refurbishment efforts elsewhere. Among other things, this will help officials determine how much of the SM-1A will remain after it’s decommissioned. “There will still be buildings there,” she said. “There will still be components of some of the old structure there that may likely remain.”

MidAmerican Energy Wind XI expands Iowa wind power with the Beaver Creek and Prairie farms, 169 turbines and 338 MW, delivering renewable energy, grid reliability, rural jobs, and long-term tax revenue through major investment.

Key Points

MidAmerican Energy Wind XI is a $3.6B Iowa wind buildout adding 2,000 MW to enhance reliability, jobs, and tax revenue.

✅ 169 turbines at Beaver Creek and Prairie deliver 338 MW.

✅ Wind supplies 36.6 percent of Iowa electricity generation.

✅ Projects forecast $62.4M in property taxes over 20 years.

Power company MidAmerican Energy recently announced the beginning of operations at two huge wind farms in the US state of Iowa.

The two projects, called Beaver Creek and Prairie, total 169 turbines and have a combined capacity of 338 megawatts (MW), enough to meet the annual electricity needs of 140,000 homes in the state.

“We’re committed to providing reliable service and outstanding value to our customers, and wind energy accomplishes both,” said Mike Fehr, vice president of resource development at MidAmerican. “Wind energy is good for our customers, and it’s an abundant, renewable resource that also energizes the economy.”

The wind farms form part of MidAmerican Energy’s major Wind XI project, which will see an extra 2,000MW of wind power built, and $3.6 billion invested amid notable wind farm acquisitions shaping the market by the end of 2019. The company estimates it is the largest economic development project in Iowa’s history.

Iowa is something of a hidden powerhouse in American wind energy. The technology provides an astonishing 36.6 percent of the state’s entire electricity generation and plays a growing role in the U.S. electricity mix according to the American Wind Energy Association (AWEA). It also has the second largest amount of installed capacity in the nation at 6917MW; Texas is first with over 21,000MW.

Along with capital investment, wind power brings significant job opportunities and tax revenues for the state. An estimated 9,000 jobs are supported by the industry, something a U.S. wind jobs forecast stated could grow to over 15,000 within a couple of years.

MidAmerican Energy is also keen to stress the economic benefits of its new giant projects, claiming that they will bring in $62.4 million of property tax revenue over their 20-year lifetime.

Tom Kiernan, AWEA’s CEO, revealed last year that, as the most-used source of renewable electricity in the U.S., wind energy is providing more than five states in the American Midwest with over 20 percent of electricity generation, “a testament to American leadership and innovation”.

“For these states, and across America, wind is welcome because it means jobs, investment, and a better tomorrow for rural communities”, he added.

UK Peak Power Prices surged as low wind speeds forced National Grid to rely on gas-fired plants and coal generation, amid soaring wholesale gas prices and weak wind generation during the energy crisis.

Key Points

UK Peak Power Prices are electricity costs at peak hours, driven by wind output, gas reliance, and market dynamics.

✅ Spikes when wind generation drops and demand rises.

✅ Driven by gas-fired plants, coal backup, and wholesale gas prices.

✅ Moderate as wind output recovers and interconnectors supply.

Low wind speeds pushed peak hour power prices to the second highest level for at least three years on Monday, a move consistent with UK electricity prices hitting a 10-year high earlier this year, as Britain’s grid was forced to increase its reliance on gas-fired power plants and draw on coal generation.

Calm weather this year has exacerbated the energy price crisis in the UK, as gas-fired power stations have had to pick up the slack from wind farms. Energy demand has surged as countries open up from pandemic restrictions, which together with lower supplies from Russia to western Europe, has sent wholesale gas prices soaring.

Power prices in the UK for the peak evening period between 5pm and 6pm on Monday surpassed £2,000 per megawatt hour, only the second time they have exceeded that level in recent years.

This was still below the levels reached at the height of the gas price crisis in mid-September, when they hit £2,500/MWh, according to the energy consultancy Cornwall Insight, whose records date back to 2018.

Low wind speeds were the main driver behind Monday’s price spike, although expectations of a pick-up in wind generation on Tuesday, after recent record wind generation days, should push them back down to similar levels seen in recent weeks, analysts said.

Despite the expansion of renewables, such as wind and solar, over the past decade, with instances of wind leading the power mix in recent months, gas remains the single biggest source of electricity generation in Britain, typically accounting for nearly 40 per cent of output.

At lunchtime on Monday, gas-fired power plants were producing nearly 55 per cent of electricity, while coal accounted for 3 per cent, reflecting more power from wind than coal in 2016 milestones. Britain’s wind farms were contributing 1.67 gigawatts or just over 4 per cent, according to data from the Drax Electrics Insights website. Over the past 12 months, wind farms have produced 21 per cent of the UK’s electricity on average.

National Grid, which manages the UK’s electricity grid, has been forced on a number of occasions in recent months to ask coal plants to fire up to help offset the loss of wind generation, after issuing a National Grid short supply warning to the market. The government announced in June that it planned to bring forward the closure of the remaining coal stations to the end of September 2024.

Ministers also committed this year to making Britain’s electricity grid “net zero carbon” by 2035, and milestones such as when wind was the main source underline the transition, although some analysts have pointed out that would not signal the end of gas generation.

Since the start of the energy crisis in August, 20 energy suppliers have gone bust as they have struggled to secure the electricity and gas needed to supply customers at record wholesale prices, with further failures expected in coming weeks.

Phil Hewitt, director of the consultancy EnAppSys, said Monday’s high prices would further exacerbate pressures on those energy suppliers that do not have adequate hedging strategies. “This winter is a good time to be a generator,” he added.

Energy companies including Orsted of Denmark and SSE of the UK have reported some of the lowest wind speeds for at least two decades this year, even though record output during Storm Malik highlighted the system's volatility.

According to weather modelling group Vortex, the strength of the wind blowing across northern Europe has fallen by as much as 15 per cent on average in places this year, which some scientists suggest could be due to climate change.

Marine Renewables Canada Offshore Wind integrates marine renewables, tidal and wave energy, advancing clean electricity, low-carbon power, supply chain development, and regulatory alignment to scale offshore wind energy projects across Canada's coasts and global markets.

Key Points

An initiative to grow offshore wind using Canada's marine strengths, shared supply chains, and regulatory synergies.

✅ Leverages tidal and wave energy expertise for offshore wind

✅ Aligns supply chain, safety, and regulatory frameworks

✅ Supports low-carbon power and clean electricity goals

With a growing global effort to develop climate change solutions and increase renewable electricity production, including the UK offshore wind growth in recent years, along with Canada’s strengths in offshore and ocean sectors, Marine Renewables Canada has made a strategic decision to grow its focus by officially including offshore wind energy in its mandate.

Marine Renewables Canada plans to focus on similarities and synergies of the resources in order to advance the sector as a whole and ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

“Many of our members working on tidal energy and wave energy projects also have expertise that can service offshore wind projects both domestically and internationally,” says Tim Brownlow, Chair of Marine Renewables Canada. “For us, offshore wind is a natural fit and our involvement will help ensure that Canadian companies and researchers are gaining knowledge and opportunities in the offshore wind sector as it grows.”

Canada has the longest coastlines in the world, giving it huge potential for offshore wind energy development. In addition to the resource, Canada has significant capabilities from offshore and marine industries that can contribute to offshore wind energy projects. The global offshore wind market is estimated to grow by over 650% by 2030 and presents new opportunities for Canadian business.

“The federal government’s recent inclusion of offshore renewables in legislation, including a plan for regulating offshore wind developed by the government, and support for emerging renewable energy technologies are important steps toward building this industry,” says Elisa Obermann, executive director of Marine Renewables Canada. “There are still challenges to address before we’ll see offshore wind energy development in Canada, but we see a great opportunity to get more involved now, increase our experience, and help inform future development.”

Like wave and tidal energy, offshore wind projects operate in harsh marine environments and development presents many of the same challenges and benefits as it does for other marine renewable energy resources. Marine Renewables Canada has recognized that there is significant overlap between offshore wind and wave and tidal energy when it comes to the supply chain, regulatory issues, and the operating environment. The association plans to focus on similarities and synergies of the resources in order to advance the sector as a whole, leveraging Canada’s opportunity in the global electricity market to ensure that clean electricity from waves, tides, rivers, and offshore wind plays a significant role in Canada’s low-carbon future.

European Electricity Market Trends 2020 highlight decarbonisation, rising renewables, EV adoption, shifting energy mix, COVID-19 impacts, fuel switching, hydro, wind and solar growth, gas price dynamics, and wholesale electricity price increases.

Key Points

EU power in 2020 saw lower emissions, more renewables, EV growth, demand shifts, and higher wholesale prices.

✅ Power sector CO2 down 14% on higher renewables, lower coal

✅ Renewables 39% vs fossil 36%; hydro, wind, solar expanded

✅ EV share hit 17%; wholesale prices rose with gas, ETS costs

According to the Market Observatory for Energy DG Energy report, the COVID-19 pandemic and favorable weather conditions are the two key drivers of the trends experienced within the European electricity market in 2020. However, the two drivers were exceptional or seasonal.

The key trends within Europe’s electricity market include:

1. Decrease in power sector’s carbon emissions

As a result of the increase in renewables generation and decrease in fossil-fueled power generation in 2020, the power sector was able to reduce its carbon footprint by 14% in 2020. The decrease in the sector’s carbon footprint in 2020 is similar to trends witnessed in 2019 when fuel switching was the main factor behind the decarbonisation trend.

However, most of the drivers in 2020 were exceptional or seasonal (the pandemic, warm winter, high
hydro generation). However, the opposite is expected in 2021, with the first months of 2021 having relatively cold weather, lower wind speeds and higher gas prices, with stunted hydro and nuclear output also cited, developments which suggest that the carbon emissions and intensity of the power sector could rise.

The European Union is targeting to completely decarbonise its power sector by 2050 through the introduction of supporting policies such as the EU Emissions Trading Scheme, the Renewable Energy Directive and legislation addressing air pollutant emissions from industrial installations, with expectations that low-emissions sources will cover most demand growth in the coming years.

According to the European Environment Agency, Europe halved its power sector’s carbon emissions in 2019 from 1990 levels.

2. Changes in energy consumption

EU consumption of electricity fell by -4% as majority of industries did not operate at full level during the first half of 2020. Although majority of EU residents stayed at home, meaning an increase in residential energy use, rising demand by households could not reverse falls in other sectors of the economy.

However, as countries renewed COVID-19 restrictions, energy consumption during the 4th quarter was closer to the “normal levels” than in the first three quarters of 2020. 

The increase in energy consumption in the fourth quarter of 2020 was also partly due to colder temperatures compared to 2019 and signs of surging electricity demand in global markets.

3. Increase in demand for EVs

As the electrification of the transport system intensifies, the demand for electric vehicles increased in 2020 with almost half a million new registrations in the fourth quarter of 2020. This was the highest figure on record and translated into an unprecedented 17% market share, more than two times higher than in China and six times higher than in the United States.

However, the European Environment Agency (EEA)argues that the EV registrations were lower in 2020 compared to 2019. EEA states that in 2019, electric car registrations were close to 550 000 units, having reached 300 000 units in 2018.

4. Changes in the region’s energy mix and increase in renewable energy generation

The structure of the region’s energy mix changed in 2020, according to the report.

Owing to favorable weather conditions, hydro energy generation was very high and Europe was able to expand its portfolio of renewable energy generation such that renewables (39%) exceeded the share of fossil fuels (36%) for the first time ever in the EU energy mix.

Rising renewable generation was greatly assisted by 29 GW of wind and solar capacity additions in 2020, which is comparable to 2019 levels. Despite disrupting the supply chains of wind and solar resulting in project delays, the pandemic did not significantly slow down renewables’ expansion.

In fact, coal and lignite energy generation fell by 22% (-87 TWh) and nuclear output dropped by 11% (-79 TWh). On the other hand, gas energy generation was not significantly impacted owing to favorable prices which intensified coal-to-gas and lignite-to-gas switching, even as renewables crowd out gas in parts of the market.

5. Retirement of coal energy generation intensify

 As the outlook for emission-intensive technologies worsens and carbon prices rise, more and more early coal retirements have been announced. Utilities in Europe are expected to continue transitioning from coal energy generation under efforts to meet stringent carbon emissions reduction targets and as they try to prepare themselves for future business models that they anticipate to be entirely low-carbon reliant.

6. Increase in wholesale electricity prices

In recent months, more expensive emission allowances, along with rising gas prices, have driven up wholesale electricity prices on many European markets to levels last seen at the beginning of 2019. The effect was most pronounced in countries that are dependent on coal and lignite. The wholesale electricity prices dynamic is expected to filter through to retail prices.

The rapid sales growth in the EVs sector was accompanied by expanding charging infrastructure. The number of high-power charging points per 100 km of highways rose from 12 to 20 in 2020.
