Tornadoes put nuclear plant out of service

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.

CCUS in the U.S. Power Sector drives investments as DOE grants, 45Q tax credits, and EPA carbon rules spur carbon capture, geologic storage, and utilization, while debates persist over costs, transparency, reliability, and emissions safeguards.

Key Points

CCUS captures CO2 from power plants for storage or use, backed by 45Q tax credits, DOE funding, and EPA carbon rules.

✅ DOE grants and 45Q credits aim to de-risk project economics.

✅ EPA rules may require capture rates to meet emissions limits.

✅ Transparency and MRV guard against tax credit abuse.

New public and private funding, including DOE $110M for CCUS announced recently, and expected strong federal power plant emissions reduction standards have accelerated electricity sector investments in carbon capture, utilization and storage,’ or CCUS, projects but some worry it is good money thrown after bad.

CCUS separates carbon from a fossil fuel-burning power plant’s exhaust through carbon capture methods for geologic storage or use in industrial and other applications, according to the Department of Energy. Fossil fuel industry giants like Calpine and Chevron are looking to take advantage of new federal tax credits and grant funding for CCUS to manage potentially high costs in meeting power plant performance requirements, amid growing investor pressure for climate reporting, including new rules, expected from EPA soon, on reducing greenhouse gas emissions from existing power plants.

Power companies have “ambitious plans” to add CCUS to power plants, estimated to cause 25% of U.S. CO2 emissions. As a result, the power sector “needs CCUS in its toolkit,” said DOE Office of Fossil Energy and Carbon Management Assistant Secretary Brad Crabtree. Successful pilots and demonstrations “will add to investor confidence and lead to more deployment” to provide dispatchable clean energy, including emerging CO2-to-electricity approaches for power system reliability after 2030,| he added.

But environmentalists and others insist potentially cost-prohibitive CCUS infrastructure, including CO2 storage hub initiatives, must still prove itself effective under rigorous and transparent federal oversight.

“The vast majority of long-term U.S. power sector needs can be met without fossil generation, and better options are being deployed and in development,” Sierra Club Senior Advisor, Strategic Research and Development, Jeremy Fisher, said, pointing to carbon-free electricity investments gaining momentum in the market. CCUS “may be needed, but without better guardrails, power sector abuses of federal funding could lead to increased emissions and stranded fossil assets,” he added.

New DOE CCUS project grants, an increased $85 per metric ton, or tonne, federal 45Q tax credit, and the forthcoming EPA power plant carbon rules and the federal coal plan will do for CCUS what similar policies did for renewables, advocates and opponents agreed. But controversial past CCUS performance and tax credit abuses must be avoided with transparent reporting requirements for CO2 capture, opponents added.

Natrium small modular reactor pairs a sodium-cooled fast reactor with molten salt storage to deliver load-following, dispatchable nuclear power, enhancing grid flexibility and peaking capacity as TerraPower and GE Hitachi pursue factory-built, affordable deployment.

Key Points

A TerraPower-GE Hitachi SMR joining a sodium-cooled reactor with molten salt storage for flexible, dispatchable power.

✅ 345 MW base; 500 MW for 5.5 hours via thermal storage

✅ Sodium-cooled coolant and molten salt storage enable load-following

✅ Backed by major utilities; factory-built modules aim lower costs

Nuclear power is the Immovable Object of generation sources. It can take days just to bring a nuclear plant completely online, rendering it useless as a tool to manage the fluctuations in the supply and demand on a modern energy grid.  

Now a firm launched by Bill Gates in 2006, TerraPower, in partnership with GE Hitachi Nuclear Energy, believes it has found a way to make the infamously unwieldy energy source a great deal nimbler, drawing on next-gen nuclear ideas — and for an affordable price. 

The new design, announced by TerraPower on August 27th, is a combination of a "sodium-cooled fast reactor" — a type of small reactor in which liquid sodium is used as a coolant — and an energy storage system. While the reactor could pump out 345 megawatts of electrical power indefinitely, the attached storage system would retain heat in the form of molten salt and could discharge the heat when needed, increasing the plant’s overall power output to 500 megawatts for more than 5.5 hours. 

“This allows for a nuclear design that follows daily electric load changes and helps customers capitalize on peaking opportunities driven by renewable energy fluctuations,” TerraPower said. 

Dubbed Natrium after the Latin name for sodium ('natrium'), the new design will be available in the late 2020s, said Chris Levesque, TerraPower's president and CEO.

TerraPower said it has the support of a handful of top U.S. utilities, including Berkshire Hathaway Energy subsidiary Pacificorp, Energy Northwest, and Duke Energy. 

The reactor's molten salt storage add-on would essentially reprise the role currently played by coal- or gas-fired power stations or grid-scale batteries: each is a dispatchable form of power generation that can quickly ratchet up or down in response to changes in grid demand or supply. As the power demands of modern grids become ever more variable with additions of wind and solar power — which only provide energy when the wind is blowing or the sun shining — low-carbon sources of dispatchable power are needed more and more, and Europe is losing nuclear power at a difficult moment for energy security. California’s rolling blackouts are one example of what can happen when not enough power is available to be dispatched to meet peak demand. 

The use of molten salt, which retains heat at extremely high temperatures, as a storage technology is not new. Concentrated solar power plants also collect energy in the form of molten salt, although such plants have largely been abandoned in the U.S. The technology could enjoy new life alongside nuclear plants: TerraPower and GE Hitachi Nuclear are only two of several private firms working to develop reactor designs that incorporate molten salt storage units, including U.K.- and Canada-based developer Moltex Energy.

The Gates-backed venture and its partner touted the "significant cost savings" that would be achieved by building major portions of their Natrium plants through not a custom but an industrial process — a defining feature of the newest generation of advanced reactors is that their parts can be made in factories and assembled on-site — although more details on cost weren't available. Reuters reported earlier that each plant would cost around $1 billion.

NuScale Power

A day after TerraPower and GE Hitachi's unveiled their new design, another nuclear firm — Portland, Oregon-based NuScale Power — announced that the U.S. Nuclear Regulatory Commission (NRC) had completed its final safety evaluation of NuScale’s new small modular reactor design.

It was the first small modular reactor design ever to receive design approval from the NRC, NuScale said. 

The approval means customers can now pursue plans to develop its reactor design confident that the NRC has signed off on its safety aspects. NuScale said it has signed agreements with interested parties in the U.S., Canada, Romania, the Czech Republic, and Jordan, and is in the process of negotiating more. 

NuScale previously said that construction on one of its plants could begin in Utah in 2023, with the aim of completing the first Power Module in 2026 and the remaining 11 modules in 2027.

NuScale’s reactor is smaller than TerraPower’s. Entirely factory-built, each of its Power Modules would generate 60 megawatts of power. The design, typical of advanced reactors, uses pressurized water reactor technology, with one power plant able to house up to 12 individual Power Modules. 

In a sign of the huge amounts of time and resources it takes to get new nuclear technology to the market’s doorstep, NuScale said it first completed its Design Certification Application in December 2016. NRC officials then spent as many as 115,000 hours reviewing it, NuScale said, in what was only the first of several phases in the review process. 

In January 2019, President Donald Trump signed into law the Nuclear Energy Innovation and Modernization Act (NEIMA), designed to speed the licensing process for advanced nuclear reactors, and the DOE under Secretary Rick Perry moved to advance nuclear development through parallel initiatives. The law had widespread bipartisan support, underscoring Democrats' recent tentative embrace of nuclear power.

An industry eager to turn the page

After a boom in the construction of massive nuclear power plants in the 1960s and 70s, the world's aging fleet of nuclear plants suffers from rising costs and flagging public support. Nuclear advocates have for years heralded so-called small modular reactors or SMRs as the cheaper and more agile successors to the first generation of plants, and policy moves such as the UK's green industrial revolution lay out pathways for successive waves of reactors. But so far a breakthrough on cost has proved elusive, and delays in development timelines have been abundant. 

Edwin Lyman, the director of nuclear power safety at the Union of Concerned Scientists, suggested on Twitter that the nuclear designs used by TerraPower and GE Hitachi had fallen short of a major innovation. “Oh brother. The last thing the world needs is a fleet of sodium-cooled fast reactors,” he wrote.  

Still, climate scientists view nuclear energy as a crucial source of zero-carbon energy, with analyses arguing that net-zero emissions may be impossible without nuclear in many scenarios, if the world stands a chance at limiting global temperature increases to well below 2 degrees Celsius above pre-industrial levels. Nearly all mainstream projections of the world’s path to keeping the temperature increase below those levels feature nuclear energy in a prominent role, including those by the United Nations and the International Energy Agency (IEA). 

According to the IEA: “Achieving the clean energy transition with less nuclear power is possible but would require an extraordinary effort.”

Asia Electricity Consumption 2025 highlights an IEA forecast of surging global power demand led by China, lagging access in Africa, rising renewables and nuclear output, stable emissions, and weather-dependent grids needing flexibility and electrification.

Key Points

An IEA forecast that Asia will use half of global power by 2025, led by China, as renewables and nuclear drive supply.

✅ Asia to use half of global electricity; China leads growth

✅ Africa just 3% consumption despite rapid population growth

✅ Renewables, nuclear expand; grids must boost flexibility

Asia will for the first time use half of the world’s electricity by 2025, even as global power demand keeps rising and Africa continues to consume far less than its share of the global population, according to a new forecast released Wednesday by the International Energy Agency.

Much of Asia’s electricity use will be in China, a nation of 1.4 billion people whose China's electricity sector is seeing shifts as its share of global consumption will rise from a quarter in 2015 to a third by the middle of this decade, the Paris-based body said.

“China will be consuming more electricity than the European Union, United States and India combined,” said Keisuke Sadamori, the IEA’s director of energy markets and security.

By contrast, Africa — home to almost a fifth of world’s nearly 8 billion inhabitants — will account for just 3% of global electricity consumption in 2025.

“This and the rapidly growing population mean there is still a massive need for increased electrification in Africa,” said Sadamori.

The IEA’s annual report predicts that low-emissions sources will account for much of the growth in global electricity supply over the coming three years, including nuclear power and renewables such as wind and solar. This will prevent a significant rise in greenhouse gas emissions from the power sector, it said.

Scientists say sharp cuts in all sources of emissions are needed as soon as possible to keep average global temperatures from rising 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels. That target, laid down in the 2015 Paris climate accord, appears increasingly doubtful as temperatures have already increased by more than 1.1 C since the reference period.

One hope for meeting the goal is a wholesale shift away from fossil fuels such as coal, gas and oil toward low-carbon sources of energy. But while some regions are reducing their use of coal and gas for electricity production, in others, soaring electricity and coal use are increasing, the IEA said.

The 134-page also report warned that surging electricity demand and supply are becoming increasingly weather dependent, a problem it urged policymakers to address.

“In addition to drought in Europe, there were heat waves in India (last year),” said Sadamori. “Similarly, central and eastern China were hit by heatwaves and drought. The United States, where electricity sales projections continue to fall, also saw severe winter storms in December, and all those events put massive strain on the power systems of these regions.”

“As the clean energy transition gathers pace, the impact of weather events on electricity demand will intensify due to the increased electrification of heating, while the share of weather-dependent renewables poised to eclipse coal will continue to grow in the generation mix,” the IEA said. “In such a world, increasing the flexibility of power systems while ensuring security of supply and resilience of networks will be crucial.”

Senate Renewable Energy Tax Credits face Finance Committee scrutiny, with Democrats urging action on tax extenders, clean energy incentives, and climate policy, while Republicans cite prior wins in wind, biodiesel, and EV credits.

Key Points

Legislative incentives debated in the Senate Finance Committee to extend and align clean energy tax benefits.

✅ Democrats press hearings and action on energy tax policy

✅ Focus on clean energy, EVs, wind, biodiesel, and resilience

✅ Grassley cites prior extenders; disputes push for bigger subsidies

A group of 27 Democratic senators is calling for action in the Senate Finance Committee on extending energy-related tax credits and examining new tax proposals, especially those that incentivize renewable energy projects and align with FERC action on aggregated DERs across the grid.

Sen. Ron Wyden, D-Ore., the ranking Democrat on the Senate Finance Committee, who recently introduced a wildfire-resilient grid bill with Sen. Merkley, led the group of Democrats in writing a letter Tuesday to Sen. Charles Grassley, R-Iowa, who chairs the committee.

“Despite numerous opportunities, including in the recent tax extenders package, the Finance Committee has failed to take action on the dozens of energy tax proposals pending before it,” they wrote. “It is critical that the Committee move to address these issues in a timely manner, along with much needed policy changes that heed warnings on regulatory rollbacks to combat the damage and growing dangers caused by global climate change.”

The number of Americans ages 65 and over is projected to nearly double by 2060. And most would prefer to age in place and hiresenior caregivers if needed.

They pointed out that the Senate Finance Committee hasn’t held a single hearing on energy tax policy during the previous congressional term, and has yet to hold one in the current one.

“The sole energy tax-related recommendation of the Committee’s temporary policy task forces was ignored in the tax extender legislation passed in December 2019, along with nearly all proposals put forward in members’ legislation this Congress,” they wrote. “This Committee must fulfill its role in examining members’ energy tax proposals and in bolstering our nation’s efforts to combat climate change, including a clean electricity standard approach that sets firm targets.”

They noted that In 2019, the global average temperature was the second highest ever recorded and the past decade was the hottest ever. The lawmakers pointed to raging wildfires and increased flooding in the western part of the U.S., as well as challenges in California’s power system during the transition, causing unprecedented destruction over the past several years. They called for tax incentives for renewable energy to help combat climate change.

“Gaps in the tax code have disadvantaged complementary technologies that could improve climate resiliency and provide additional emissions reductions,” they wrote. “While power sector emissions continue to decrease, emissions from transportation, heavy industry and agriculture have stayed level or increased over the past 10 years, even amid $5 gas not spurring a green shift in consumer behavior. The United States is not on pace to meet its international climate commitments, to say nothing of the reductions necessary to stave off the worst potential outcomes of global warming.”

Grassley reacted to the letter, noting that he had worked to get tax extenders legislation passed, even as some states consider bans on clean energy use by utilities. "I begged Democrats for a year to help me get an extenders package passed, about half of which were green energy policies, so this rings hollow," he said in a statement Tuesday. "We wouldn’t have a wind energy credit or a biodiesel credit but for me, let alone an extension of either. Democrats were holding up these green energy provisions in an attempt to get a big expansion of taxpayer subsidies for rich Tesla owners."

Agrivoltaics in Alberta integrates solar energy with agriculture, boosting crop yields and water conservation. The Strathmore Solar project showcases dual land use, sheep grazing for vegetation control, and PPAs that expand renewable energy capacity.

Key Points

A dual-use model where solar arrays and farming co-exist, boosting yields, saving water, and diversifying revenue.

✅ Strathmore Solar: 41 MW on 320 acres with managed sheep grazing

✅ 25-year TELUS PPA secures power and renewable energy credits

✅ Panel shade cuts irrigation needs and protects crops from extremes

Alberta is emerging as a leader in agrivoltaics—the innovative practice of integrating solar energy production with agricultural activities, aligning with the province's red-hot solar growth in recent years. This approach not only generates renewable energy but also enhances crop yields, conserves water, and supports sustainable farming practices. A notable example of this synergy is the Strathmore Solar project, a 41-megawatt solar farm located on 320 acres of leased industrial land owned by the Town of Strathmore. Operational since March 2022, it exemplifies how solar energy and agriculture can coexist and thrive together.

The Strathmore Solar Initiative

Strathmore Solar is a collaborative venture between Capital Power and the Town of Strathmore, with a 25-year power purchase agreement in place with TELUS Corporation for all the energy and renewable energy credits generated by the facility. The project not only contributes significantly to Alberta's renewable energy capacity, as seen with new solar facilities contracted at lower cost across the province, but also serves as a model for agrivoltaic integration. In a unique partnership, 400 to 600 sheep from Whispering Cedars Ranch are brought in to graze the land beneath the solar panels. This arrangement helps manage vegetation, reduce fire hazards, and maintain the facility's upkeep, all while providing shade for the grazing animals. This mutually beneficial setup maximizes land use efficiency and supports local farming operations, illustrating how renewable power developers can strengthen outcomes with integrated designs today. 

Benefits of Agrivoltaics in Alberta

The integration of solar panels with agricultural practices offers several advantages for a province that is a powerhouse for both green energy and fossil fuels already across sectors:

• Enhanced Crop Yields: Studies have shown that crops grown under solar panels can experience increased yields due to reduced water evaporation and protection from extreme weather conditions.
  
  

• Water Conservation: The shade provided by solar panels helps retain soil moisture, leading to a decrease in irrigation needs.
  
  

• Diversified Income Streams: Farmers can generate additional revenue by selling renewable energy produced by the solar panels back to the grid.
  
  

• Sustainable Land Use: Agrivoltaics allows for dual land use, enabling the production of both food and energy without the need for additional land.
  
  

These benefits are evident in various agrivoltaic projects across Alberta, where farmers are successfully combining crop cultivation with solar energy production amid a renewable energy surge that is creating thousands of jobs.

Challenges and Considerations

While agrivoltaics presents numerous benefits, there are challenges to consider as Alberta navigates challenges with solar expansion today across Alberta:

• Initial Investment: The setup costs for agrivoltaic systems can be high, requiring significant capital investment.
  
  

• System Maintenance: Regular maintenance is essential to ensure the efficiency of both the solar panels and the agricultural operations.
  
  

• Climate Adaptability: Not all crops may thrive under the conditions created by solar panels, necessitating careful selection of suitable crops.

Addressing these challenges requires careful planning, research, and collaboration between farmers, researchers, and energy providers.

Future Prospects

The success of projects like Strathmore Solar and other agrivoltaic initiatives in Alberta indicates a promising future for this dual-use approach. As technology advances and research continues, agrivoltaics could play a pivotal role in enhancing food security, promoting sustainable farming practices, and contributing to Alberta's renewable energy goals. Ongoing projects and partnerships aim to refine agrivoltaic systems, making them more efficient and accessible to farmers across the province.

The integration of solar energy production with agriculture in Alberta is not just a trend but a transformative approach to sustainable farming. The Strathmore Solar project serves as a testament to the potential of agrivoltaics, demonstrating how innovation can lead to mutually beneficial outcomes for both the agricultural and energy sectors.
