Wind technology testing center gets $25 million

Solar Plus Storage is accelerating across utilities and microgrids, pairing rooftop solar with lithium-ion batteries to enhance grid resilience, reduce peak costs, prevent blackouts, and leverage tax credits amid falling prices and decarbonization goals.

Key Points

Solar Plus Storage combines solar generation with batteries to shift load, boost reliability, and cut energy costs.

✅ Cuts peak demand charges and enhances blackout resilience

✅ Falling battery and solar costs drive nationwide utility adoption

✅ Enables microgrids and grid services like frequency regulation

Todd Karin was prepared when California’s largest utility shut off power to millions of people to avoid the risk of wildfires last month. He’s got rooftop solar panels connected to a single Tesla Powerwall in his rural home near Fairfield, California. “We had backup power the whole time,” Karin says. “We ran the fridge and watched movies.”

Californians worried about an insecure energy future are increasingly looking to this kind of solution. Karin, a 31-year-old postdoctoral fellow at Lawrence Berkeley National Laboratory, spent just under $4,000 for his battery by taking advantage of tax credits. He's also saving money by discharging the battery on weekday evenings, when energy is more expensive during peak demand periods. He expects to save around $1,500 over the 10 years the battery is under warranty.

The economics don’t yet work for every household, but the green-power combo of solar panels plus batteries is popping up on a much bigger scale in some unexpected places. Owners of a rice processing plant in Arkansas are building a system to generate 26 megawatts of solar power and store another 40 MW. The plant will cut its power bill by a third, and owners say they will pass the savings to local rice growers. New York’s JFK Airport is installing solar plus storage to reduce its power load by 10 percent, while Pittsburgh International Airport is building a 20-MW solar and natural gas microgrid to keep it independent from the local utility. Officials at both airports are worried about recent power shutdowns due to weather and overload-related blackouts.

And residents of the tiny northern Missouri town of Green City (pop. 608) are getting 2.5 MW of solar plus four hours of battery storage from the state’s public utility next year. The solar power won’t go directly to townspeople, but instead will back up the town’s substation, reducing the risk of a potential shutdown. It’s part of a $68 million project to improve the reliability of remote substations far from electric generating stations.

“It’s a pretty big deal for us,” says Chad Raley, who manages technology and renewables at Ameren, a Missouri utility that is building three rural solar-plus-storage projects to better manage the flow of electricity across the local grid. “It gives us so much flexibility with renewable generation. We can’t control the sun or clouds or wind, but we can have battery storage.”

The first solar-plus-storage installations started about a decade ago on a small scale in sunny states like California, Hawaii, and Arizona. Now they’re spreading across the country, driven by falling prices of both solar panels and lithium-ion batteries the size of a shipping container imported from both China and South Korea, with wind, solar, and batteries making up most of the utility-scale pipeline nationwide. These countries have ramped up production efficiencies and lowered labor costs, leaving many US manufacturers in the dust. In fact, the price of building a comparable solar-plus-storage generating facility is now cheaper than operating a coal-fired power plant, industry officials say. In certain circumstances, the cost is equal to some natural gas plants.

“This is not just a California, New York, Massachusetts thing,” says Kelly Speakes-Backman, CEO of the Energy Storage Association, an industry group in Washington. She says more than 30 states have renewable storage on the grid. Utilities have proposed and states have approved 7 gigawatts to be installed by 2030, and most new storage will be paired with solar across the US.

Speakes-Backman estimates the unit cost of electricity produced from a solar-plus-storage system will drop 10 to 15 percent each year through 2024, supporting record growth in solar and storage investments. “If you have the option of putting out a polluting or non-polluting generating source at the same price, what are you going to pick?” says Speakes-Backman.

She notes that PJM, a large Mid-Atlantic wholesale grid operator, announced it will deploy battery storage to help smooth out fluctuating power from two wind farms it operates. “When the grid fluctuates, storage can react to it quickly and can level out the supply,” she says. In the Midwest, grid-level battery storage is also being used to absorb extra wind power. Batteries hold onto the wind and put it back onto the grid when people need it.

While the solar-plus-storage trend isn’t yet putting a huge dent in our fossil fuel use, according to Paul Denholm, an energy analyst at the National Renewable Energy Laboratory in Golden, Colorado, it is a good beginning and has the side effect of cutting air pollution. By 2021, solar and other renewable energy sources will overtake coal as a source of energy, and the US is moving toward 30% electricity from wind and solar, according to a new report by the Institute for Energy Economics and Financial Analysis, a nonprofit think tank based in Cleveland.

That’s a glimmer of hope in a somewhat dreary week of news on carbon emissions. A new United Nations report released this week finds that the planet is on track to warm by 3.9 degrees Celsius (7 Fahrenheit) by 2100 unless drastic cuts are made by phasing out gas-powered cars, eliminating new coal-fired power plants, and changing how we grow and manage land, and scientists are working to improve solar and wind power to limit climate change as well.

Energy-related greenhouse gas emissions in the US rose 2.7 percent in 2018 after several years of decline. The Trump administration has rolled back climate policies from the Obama years, including withdrawing from the Paris climate accords.

There may be hope from green power initiatives outside the Beltway, though, and from federal proposals like a tenfold increase in US solar that could remake the electricity system. Arizona plans to boost solar-plus-storage from today’s 6 MW to a whopping 850 MW by 2025, more than the entire capacity of large-scale batteries in the US today. And some folks might be cheering the closing of the West’s biggest coal-fired power plant, the 2.25-gigawatt Navajo Generating Station, in Arizona, which had spewed soot and carbon dioxide over the region for 45 years until last week. The closure might help the planet and clear the hazy smog over the Grand Canyon.

UK Coal Phase-Out marks record-low coal generation as the UK grid shifts to renewable power, wind farms, and a net zero trajectory, slashing carbon emissions and supporting cleaner EV charging across the electricity system.

Key Points

UK Coal Phase-Out ends coal-fired electricity nationwide, powered by renewables and net zero policy to cut grid carbon.

✅ Coal's Q2 share fell to 0.7%, a record low

✅ Renewables up 12% with Beatrice wind farm

✅ EV charging grows cleaner as grid decarbonizes

The share of coal in the UK’s electricity system has fallen to record lows in recent months, alongside a coal-free power record, according to government data.

The figures show electricity generated by the UK’s most polluting power plants made up an average of 0.7% of the total in the second quarter of this year, a shift underway since wind first outpaced coal in 2016 across the UK. The amount of coal used to power the electricity grid fell by almost two-thirds compared with the same months last year.

A government spokesperson said coal-generated energy “will soon be a distant memory” as the UK moves towards becoming a net zero emissions economy, despite signs that low-carbon generation stalled in 2019 in some analyses.

“This new record low is a result of our world-leading low-carbon energy industry, which provided more than half of our energy last year and continues to go from strength to strength as we aim to end our contribution to climate change entirely by 2050,” the spokesperson said.

The UK electricity market is on track to end coal power after 142 years by the government’s target date of 2025.

This year three major energy companies have announced plans to close coal-fired power plants in the UK, which would leave only four remaining after the coming winter, ahead of the last coal power station going offline nationwide.

RWE said this month it would close the Aberthaw B power station in south Wales, its last UK coal plant, after the winter. SSE will close the Fiddler’s Ferry plant near Warrington, Cheshire, in March 2020, and EDF Energy will shutter the Cottam coal plant in September.

So far this year the UK has gone more than 3,000 hours without using coal for power, including a full week without coal earlier in the year – nearly five times more than the whole of 2017.

Meanwhile, the government’s data shows that renewable energy climbed by 12% from the second quarter of last year, boosted by the startup of the Beatrice windfarm in the Moray Firth in Scotland, and the UK leading the G20 in wind power share in recent assessments.

The cleaner power system could accelerate carbon savings from the UK’s roads, too, as more drivers opt for electric vehicles. A study by Imperial College London for the energy company Drax found that the UK’s increasingly low-carbon energy system meant electric cars were a greener option even when taking into account the carbon emissions produced by making car batteries.

Dr Iain Staffell, of Imperial College London, said: “An electric vehicle in the UK simply cannot be more polluting than its petrol or diesel equivalent – even when taking into account the upfront carbon cost of manufacturing their batteries. Any EV bought today could be emitting just a tenth of what a petrol car would in as little as five years’ time, as the electricity it uses to charge comes from an increasingly low-carbon mix.”

EU Electricity Market Reform advances two-way CfDs, PPAs, and fixed-price tariffs to cut volatility, support renewables and nuclear, stabilize investor revenues, and protect consumers from price spikes across wholesale power markets.

Key Points

An EU plan expanding two-way CfDs, PPAs, and fixed-price contracts to curb price swings and support low-carbon power.

✅ Two-way CfDs return excess revenues to consumers

✅ Boosts PPAs and fixed-price retail options

✅ Targets renewables, nuclear; limits fossil exposure

The European Union wants to expand the use of contracts that pay power plants a fixed price for electricity, a draft proposal showed, as part of an electricity market revamp to shield European consumers from big price swings.

The European Commission pledged last year to reform the EU's electricity market rules, after record-high gas prices, caused by cuts to Russian flows, sent power prices soaring, prompting debates over gas price cap strategies in response.

A draft of the EU executive's proposal, seen by Reuters on Tuesday and due to be published on Mar. 16, steered clear of the deep redesign of the electricity market that some member states have called for, even as nine EU countries opposed sweeping reforms as a fix earlier in the crisis, suggesting instead limited changes to nudge countries towards more predictable, fixed-price power contracts.

If EU countries want to support new investments in wind, solar, geothermal, hydropower and nuclear electricity, for example - a point over which France and Germany have wrestled - they should use a two-way contract for difference (CfD) or an equivalent contract, the draft said.

The aim is to provide a stable revenue stream to investors, and help make consumers' energy bills less volatile, even though rolling back electricity prices is tougher than it appears. Restricting this support to renewable and low-carbon electricity also aims to speed up Europe's shift away from fossil fuels.

Two-way CfDs offer generators a fixed "strike price" for their electricity, regardless of the price in short-term energy markets. If the market price is above the CfD strike price, then the extra revenue the generator receives should be handed out to final electricity consumers, the draft EU document said.

Countries should also make it easier for power buyers to sign power purchase agreements (PPA) - another type of long-term contract to directly buy electricity from a generator.

Governments should also make sure consumers have access to fixed-price electricity contracts - echoing France's new electricity pricing scheme to reassure Brussels - giving them the option to avoid a contract that would expose them to volatile prices swings in energy markets, the draft said.

If European energy prices were to spike to extreme levels again, the Commission suggested allowing national governments to temporarily intervene to fix prices while weighing emergency measures to limit prices where needed, and offer consumers and small businesses a share of their electricity at a lower price.

IAEA Nuclear Security Mission in China reviews regulatory frameworks, physical protection, and compliance at nuclear power plants, endorsing CAEA efforts, IPPAS guidance, and capacity building to strengthen safeguards, risk management, and global cooperation.

Key Points

An IAEA advisory visit assessing China's nuclear security, physical protection, and regulatory frameworks.

✅ Reviews laws, regulations, and physical protection measures

✅ Endorses CAEA, COE, and IPPAS-aligned best practices

✅ Recommends accelerated rulemaking for expanding reactors

The International Atomic Energy Agency commended China's efforts and accomplishments in nuclear security after conducting its first nuclear security advisory mission to the nation, according to the China Atomic Energy Authority.

The two-week International Physical Protection Advisory Service mission, from Aug 28to Saturday, reviewed the legislative and regulatory framework for nuclear security as well as the physical protection of nuclear material and facilities, including worker safety protocols during health emergencies.

An eight-member expert team led by Joseph Sandoval of the United States' Sandia National Laboratories visited Fangjiashan Nuclear Power Plant, part of the Qinshan Nuclear Power Station in Zhejiang province, to examine security arrangements and observe physical protection measures, where recognized safety culture practices can reinforce performance.

The experts also met with officials from several Chinese government bodies involved in nuclear security such as the China Atomic Energy Authority, National Nuclear Safety Administration and Ministry of Public Security.

The international agency has carried out 78 of the protection missions in 48 member states since 1995. This was the first in China, it said.

The China Atomic Energy Authority said on Tuesday that a report by the experts highly approves of the Chinese government's continuous efforts to strengthen nuclear safety, to boost the sustainable development of the nuclear power industry and to help establish a global nuclear security system.

The report identifies the positive roles played by the State Nuclear Security Technology Center and its subsidiary, the Center of Excellence on Nuclear Security, in enhancing China's nuclear security capability and supporting regional and global cooperation in the field, such as bilateral cooperation agreements that advance research and standards, officials at the China Atomic Energy Authority said.

"A strong commitment to nuclear security is a must for any state that uses nuclear power for electricity generation and that is planning to significantly expand this capacity by constructing new power reactors," said Muhammad Khaliq, head of the international agency's nuclear security of materials and facilities section. "China'sexample in applying IAEA nuclear security guidance and using IAEA advisory services demonstrates its strong commitment to nuclear security and its enhancement worldwide."

The report notes that along with the rapid growth of China's nuclear power sector, challenges have emerged when it comes to the country's nuclear security mechanism and management, as highlighted by grid reliability warnings during pandemics in other markets.

It suggests that the Chinese government accelerate the making of laws and regulations to better govern this sector.

Deng Ge, director of the State Nuclear Security Technology Center, said the IAEAmission would help China strengthen its nuclear security since the nation could learn from other countries' successful experience, including on-site staffing measures to maintain critical operations, and find out its weaknesses for rectification.

Deng added that the mission's report can help the international community understand China's contributions to the global nuclear security system and also offer China's best practices to other nations.

Hungary's Russian Energy Dependence underscores EU tensions, as TurkStream gas flows, discounted imports, and pipeline reliance challenge sanctions, energy security, diversification, and decoupling goals amid Ukraine war pressures and bloc unity concerns.

Key Points

It is Hungary's reliance on Russian gas and oil via TurkStream, complicating EU sanctions and energy independence.

✅ 85% gas, 60% oil imports from Russia via TurkStream pipelines.

✅ Discounted contracts seldom cut bills; security cited by Budapest.

✅ EU decoupling targets hampered; sanctions leverage and unity erode.

Hungary's energy policies have positioned it as a notable outlier within the European Union, particularly in the context of the ongoing geopolitical tensions stemming from Russia's invasion of Ukraine. While the EU has been actively working to reduce its dependence on Russian energy sources through an EU $300 billion plan to dump Russian energy, Hungary has maintained and even strengthened its energy ties with Moscow, raising concerns about EU unity and the effectiveness of sanctions.

Strategic Energy Dependence

Hungary's energy infrastructure is heavily reliant on Russian supplies. Approximately 85% of Hungary's natural gas and more than 60% of its oil imports originate from Russia. This dependence is facilitated through pipelines such as TurkStream, which delivers Russian gas to Hungary via Turkey and the Balkans amid Europe's energy nightmare over price volatility and security. In 2025, Hungary's gas imports through TurkStream are projected to reach 8 billion cubic meters, a significant increase from previous years. These imports are often secured at discounted rates, although such savings may not always be passed on to Hungarian consumers.

Political and Economic Considerations

Prime Minister Viktor Orbán has been a vocal critic of EU sanctions against Russia and has consistently blocked EU initiatives aimed at providing military aid to Ukraine, even as Ukraine leans on power imports to keep the lights on. His government argues that Russia's military capabilities make it an unyielding adversary and that a ceasefire would only solidify its territorial gains. Orbán's stance has led to Hungary's isolation within the EU on matters related to the conflict in Ukraine.

Economically, Hungary's reliance on Russian energy has been justified by the government as a means to maintain low energy prices for consumers and ensure energy security. However, critics argue that this strategy undermines EU efforts to achieve energy independence and reduces the bloc's leverage over Russia amid a global energy war marked by price hikes and instability.

EU's Response and Challenges

The European Union has set ambitious goals to reduce its reliance on Russian energy, aiming to halt imports of Russian natural gas by the end of 2027 and prohibit new contracts starting in 2025 while exploring gas price cap strategies to contain market volatility. However, Hungary's continued imports of Russian energy complicate these efforts. The TurkStream pipeline, in particular, has become a focal point in discussions about the EU's energy strategy, as it enables ongoing Russian gas exports to Europe despite the bloc's broader decoupling initiatives.

Hungary's actions have raised concerns among other EU member states about the effectiveness of the sanctions regime and the potential for other countries to exploit similar loopholes. There are calls for stricter policies, including banning spot gas purchases and enforcing traceability of gas origins, and consideration of emergency measures to limit electricity prices to ensure genuine energy independence and reduce overreliance on external suppliers.

Hungary's steadfast energy relationship with Russia presents a significant challenge to the European Union's collective efforts to reduce dependence on Russian energy sources. While Hungary argues that its energy strategy is in the national interest, it risks undermining EU solidarity and the bloc's broader geopolitical objectives. As the EU continues to navigate its energy transition and response to the ongoing conflict in Ukraine, including energy ceasefire violations reported by both sides, Hungary's position will remain a critical point of contention within the union.

Texas Electricity Market Bailout proposes securitization bonds and ERCOT-backed fees after Winter Storm Uri, spreading costs via ratepayer charges on power bills to stabilize generators, co-ops, and retailers and avert bankruptcies and investor flight.

Key Points

State plan to securitize storm debts via ERCOT fees, adding bill charges to stabilize Texas power firms.

✅ Securitization bonds finance unpaid ancillary services and energy costs

✅ ERCOT fee spreads Winter Storm Uri debts across ratepayers statewide

✅ Aims to prevent bankruptcies, preserve grid reliability, reassure investors

An approximately $2.5 billion plan to bail out Texas’ distressed electricity market from the financial crisis caused by Winter Storm Uri in February has been approved by the Texas House.

The legislation would impose a fee — likely for the next decade or longer — on electricity companies, which would then get passed on to residential and business customers in their power bills, even as some utilities waived certain fees earlier in the crisis.

House lawmakers sent House Bill 4492 to the Senate on Thursday after a 129-15 vote. A similar bill is advancing in the Senate.

Some of the state’s electricity providers and generators are financially underwater in the aftermath of the February power outages, which left millions without power and killed more than 100 people. Electricity companies had to buy whatever power was available at the maximum rate allowed by Texas regulations — $9,000 per megawatt hour — during the week of the storm (the average price for power in 2020 was $22 per megawatt hour). Natural gas fuel prices also spiked more than 700% during the storm.

Several companies are nearing default on their bills to the Electric Reliability Council of Texas, which manages the Texas power grid that covers most of the state and facilitates financial transactions in it.

Rural electric cooperatives were especially hard hit; Brazos Electric Power Cooperative, which supplies electricity to 1.5 million customers, filed for bankruptcy citing a $1.8 billion debt to ERCOT.

State Rep. Chris Paddie, R-Marshall, the bill’s author, said a second bailout bill will be necessary during the current legislative session for severely distressed electric cooperatives.

“This is a financial crisis, and it’s a big one,” James Schaefer, a senior managing director at Guggenheim Partners, an investment bank, told lawmakers at a House State Affairs Committee hearing in early April. He warned that more bankruptcies would cause higher costs to customers and hurt the state’s image in the eyes of investors.

“You’ve got to free the system,” Schaefer said. “It’s horrible that a bunch of folks have to pay, but it’s a system-wide failure. If you let a bunch of folks crash, it’s not a good look for your state.”

If approved by the Senate and Gov. Greg Abbott, a newly-created Texas Electric Securitization Corp. would use the money raised from the fees for bonds to help pay the companies’ debts, including costs for ancillary services, a financial product that helps ensure power is continuously generated and improve electricity reliability across the grid.

Paddie told his colleagues Wednesday that he could not yet estimate how long the new fee would be imposed, but during committee hearings lawmakers estimated it’s likely to be at least a decade. Several other bills to spread out the costs of the winter storm and consider market reforms are also moving through the Legislature.

ERCOT’s independent market monitor recommended in March that energy sold during that period be repriced at a lower rate, which would have allowed ERCOT to claw back about $4.2 billion in payments to power generators, but the Public Utility Commission declined to do so, even as a court ruling on plant obligations in emergencies drew scrutiny among market participants.

Instead, lawmakers are pushing for bailouts that several energy experts have said is needed, both to ensure distressed companies don’t pass enormous costs on to their customers and to prevent electricity investors and companies from leaving the state if it’s viewed as too risky to continue doing business.

Becky Klein, an energy consultant in Austin and former chair of the Public Utility Commission who played a key role in de-regulating Texas’ electricity market two decades ago, said during a retail electricity panel hosted by Integrate that legislation is necessary to provide “some kind of backstop during a crazy market crisis like this to show the financial market that we’re willing to provide some relief.”

Still, some lawmakers are concerned with how they will win public support, including potential voter-approved funding measures, for bills to bail out the state’s electricity market.

“I have to go back to Laredo and say, ‘I know you didn’t have electricity for several days, but now I’m going to make you pay a little more for the next 20 years,’” state Rep. Richard Peña Raymond, D-Laredo, said during an early April discussion on the plan in the House State Affairs Committee. He said he voted for the bill because it’s in the best interest of the state.

Paddie, during the same committee hearing, acknowledged that “none of us want to increase fees or taxes.” However, he said, “We have to deal with the reality set before us.”
