Temperatures approaching 100 degrees have started to slowly sap away the water Lake Norman had gained in the past six months.

The lake level at Lake Norman has dipped 0.3 feet in the past 10 days. While that put the lake at its target level, the rapid evaporation, and the expected dry, hot conditions of the next week, will keep Duke Energy officials and others monitoring the water. Duke is in a Stage 3 drought program.

Duke Energy spokeswoman Marilyn Lineberger said the Drought Management Advisory Group - which includes Duke Energy, local municipalities and local businesses - won't make any decisions about further restrictions until its June 25 meeting. Duke Energy is not granting permits for new pumps at residential properties and said other properties also face restrictions.

Lake residents can still pump water from the lake on Saturdays, but that could change if the high evaporation levels continue, officials said.

"We weren't seeing conditions like this until August last year," Joe Klutz of Duke Energy told the Lake Norman Marine Commission. Lineberger said the group will look at drought monitors, stream flows, lake levels and other indicators to make a determination.

Each jurisdiction makes its own decisions, while Duke controls lake pumps and lake levels.

"Droughts evolve over a period of time," Lineberger said. "Collaboration is very important." Lineberger said that includes conserving resources.

"Everyone, whether they are on the lake or not, needs to change their behavior," Lineberger said. "We all need to conserve water. That goes a long way."

China to build 525-MW hydropower station on Yangtze tributary

Baima Hydropower Station advances China renewable energy on the Wujiang River, a Yangtze tributary in Chongqing; a 525 MW cascade project approved by NDRC, delivering 1.76 billion kWh and improving river shipping.

 

Key Points

An NDRC-approved 525 MW project on Chongqing's Wujiang River, producing 1.76 billion kWh and improving navigation.

✅ 10.2 billion yuan investment; final cascade plant on Wujiang in Chongqing

✅ Expected output: 1.76 billion kWh; capacity 525 MW; NDRC approval

✅ Improves river shipping; relocation of 5,000 residents in Wulong

 

China plans to build a 525-MW hydropower station on the Wujiang River, a tributary of the Yangtze River, in Southwest China's Chongqing municipality, aligning with projects like the Lawa hydropower station elsewhere in the Yangtze basin.

The Baima project, the last of a cascade of hydropower stations on the section of the Wujiang River in Chongqing, has gotten the green light from the National Development and Reform Commission, China's state planning agency, even as some independent power projects elsewhere face uncertainty, such as the Siwash Creek project in British Columbia, the Chongqing Municipal Commission of Development and Reform said Monday.

The project, in Baima township of Wulong district, is expected to involve an investment of 10.2 billion yuan ($1.6 billion), as China explores compressed air generation to bolster grid flexibility, it said.

U.S. renewable electricity surpassed coal in 2022

2022 US Renewable Power Milestone highlights EIA data: wind and solar outpaced coal and nuclear, hydropower contributed, with falling levelized costs, grid integration, battery storage, and transmission upgrades shaping affordable, reliable clean power growth.

 

Key Points

The year US renewables, led by wind and solar, generated more power than coal and nuclear, per EIA.

✅ Wind and solar rose; levelized costs fell 70%-90% over decade

✅ Renewables surpassed coal and nuclear in 2022 per EIA

✅ Grid needs storage and transmission to manage intermittency

 

Electricity generated from renewables surpassed coal in the United States for the first time in 2022, as wind and solar surpassed coal nationwide, the U.S. Energy Information Administration has announced.

Renewables also surpassed nuclear generation in 2022 after first doing so last year, and wind and solar together generated more electricity than nuclear for the first time in the United States.

Growth in wind and solar significantly drove the increase in renewable energy and contributed 14% of the electricity produced domestically in 2022, with solar producing about 4.7% of U.S. power overall. Hydropower contributed 6%, and biomass and geothermal sources generated less than 1%.

“I’m happy to see we’ve crossed that threshold, but that is only a step in what has to be a very rapid and much cheaper journey,” said Stephen Porder, a professor of ecology and assistant provost for sustainability at Brown University.

California produced 26% of the national utility-scale solar electricity followed by Texas with 16% and North Carolina with 8%.

The most wind generation occurred in Texas, which accounted for 26% of the U.S. total, while wind is now the most-used renewable electricity source nationwide, followed by Iowa (10%) and Oklahoma (9%).

“This booming growth is driven largely by economics,” said Gregory Wetstone, president and CEO of the American Council on Renewable Energy, as renewables became the second-most prevalent U.S. electricity source in 2020 nationwide. “Over the past decade, the levelized cost of wind energy declined by 70 percent, while the levelized cost of solar power has declined by an even more impressive 90 percent.”

“Renewable energy is now the most affordable source of new electricity in much of the country,” added Wetstone.

The Energy Information Administration projected that the wind share of the U.S. electricity generation mix will increase from 11% to 12% from 2022 to 2023 and that solar will grow from 4% to 5% during the period, and renewables hit a record 28% share in April according to recent data. The natural gas share is expected to remain at 39% from 2022 to 2023, and coal is projected to decline from 20% last year to 17% this year.

“Wind and solar are going to be the backbone of the growth in renewables, but whether or not they can provide 100% of the U.S. electricity without backup is something that engineers are debating,” said Brown University’s Porder.

Many decisions lie ahead, he said, as the proportion of renewables that supply the energy grid increases, with renewables projected to soon be one-fourth of U.S. electricity generation over the near term.

This presents challenges for engineers and policy-makers, Porder said, because existing energy grids were built to deliver power from a consistent source. Renewables such as solar and wind generate power intermittently. So battery storage, long-distance transmission and other steps will be needed to help address these challenges, he said.

California scorns fossil fuel but can't keep the lights on without it

California fossil fuel grid reliability plan addresses heat wave demand, rolling blackouts, and grid stability by temporarily procuring gas generation while accelerating renewables, storage, and transmission to meet clean energy and carbon-neutral targets by 2045.

 

Key Points

A stop-gap policy to prevent blackouts by buying fossil power while fast-tracking renewables, storage, and grid upgrades.

✅ Temporary procurement of gas to avoid rolling blackouts

✅ Accelerates renewables, storage, transmission permitting

✅ Aims for carbon neutrality by 2045 without new gas plants

 

California wants to quit fossil fuels. Just not yet Faced with a fragile electrical grid and the prospect of summertime blackouts, the state agreed to put aside hundreds of millions of dollars to buy power from fossil fuel plants that are scheduled to shut down as soon as next year.

That has prompted a backlash from environmental groups and lawmakers who say Democratic Gov. Gavin Newsom’s approach could end up extending the life of gas plants that have been on-track to close for more than a decade and could threaten the state’s goal to be carbon neutral by 2045.

“The emphasis that the governor has been making is ‘We’re going to be Climate Leaders; we’re going to do 100 percent clean energy; we’re going to lead the nation and the world,’” said V. John White, executive director of the Sacramento-based Center for Energy Efficiency and Renewable Technologies, a non-profit group of environmental advocates and clean energy companies. “Yet, at least a part of this plan means going the opposite direction.”

That plan was a last-minute addition to the state’s energy budget, which lawmakers in the Democratic-controlled Legislature reluctantly passed. Backers say it’s necessary to avoid the rolling blackouts like the state experienced during a heat wave in 2020. Critics see a muddled strategy on energy, and not what they expected from a nationally ambitious governor who has made climate action a centerpiece of his agenda.

The legislation, which some Democrats labeled as “lousy” and “crappy,” reflects the reality of climate change. Heat waves are already straining power capacity, and the transition to cleaner energy isn’t coming fast enough to meet immediate needs in the nation’s most populous state.

Officials have warned that outages would be possible this summer, as the grid faces heat wave tests again, with as many as 3.75 million California homes losing power in a worst-case scenario of a West-wide heat wave and insufficient electrical supplies, particularly in the evenings.

It’s also an acknowledgment of the political reality that blackout politics are hazardous to elected officials, even in a state dominated by one party.

Newsom emphasized that the money to prop up the power grid, part of a larger $4.3 billion energy spending package, is meant as a stop-gap measure. The bill allows the Department of Water Resources to spend $2.2 billion on “new emergency and temporary generators, new storage systems, clean generation projects, and funding on extension of existing generation operations, if any occur,” the governor said in a statement after signing the bill.

“Action is needed now to maintain reliable energy service as the State accelerates the transition to clean energy,” Newsom said.

Following the signing, the governor called for the state California Air Resources Board to add a set of ambitious goals to its 2022 Scoping Plan, which lays out California’s path for reducing carbon emissions.

Among Newsom’s requested changes is a move away from fossil fuels, asking state agencies to prepare for an energy transition that avoids the need for new natural gas plants.

Alex Stack, a spokesman for the governor, said in a statement that California has been a global leader in reducing pollution and exporting energy policies across Western states, and pointed to Newsom’s recent letter to the Air Resources Board as well as one sent to President Joe Biden outlining how states can work with the federal government to combat climate change.

“California took action to streamline permitting for clean energy projects to accelerate the build out of clean energy that is needed to meet our climate goals and help maintain reliability in the face of extreme heat, wildfires, and drought,” Stack said.

But the prospect of using state money on fossil fuel power, even in the short term, has raised ire among the state’s many environmental advocacy groups, and raised questions about whether California will be able to achieve its goals.

“What is so frustrating about an energy bill like this is that we are at crunch time to meet these goals,” said Mary Creasman, CEO of California Environmental Voters. “And we’re investing a scale of funding into things that exacerbate those goals.”

With climate change-induced drought and high temperatures continuing to ravage the West, California anticipates the demand on the grid will only continue to grow. Despite more than a decade of bold posturing and efforts to transition to solar, wind and hydropower, the state worries it doesn’t have enough renewable energy sources on hand to keep the power on in an emergency right now, amid a looming shortage that will test reliability.

The specter of power outages poses a hazard to Newsom, and Democrats in general, especially ahead of November. While the governor is widely expected to sail to reelection, rolling blackouts are a serious political liability — in 2003, they were the catalyst for recalling Democratic Gov. Gray Davis. A lack of power isn’t just about people sweating in the dark, said Steven Maviglio, a longtime Democratic consultant who served as communications director for Davis, it can affect businesses, travel and have an outsized impact on the economy.

It behooves any state official to keep the power on, but, unlike Davis, Newsom is under serious pressure to make sure the state also adheres to its climate goals.

“Gavin Newsom’s brand is based on climate change and clean air, so it’s a little more difficult for him to say ‘well that’s not as important as keeping the power on,’” Maviglio said.

The same bill effectively ends local government control over those projects, for the time being. It hopes to speed up the state’s production of renewable energy sources by giving exclusive authority over the siting of those projects to a single state agency for the next seven years.

Environmental advocates say the state is now scrambling to address an issue they’ve long known was coming. In 2010, California officials set a schedule to retire a number of coastal gas plants that rely on what’s known as once-through cooling systems, which are damaging to the environment, especially marine life, even as regulators weigh more power plants to maintain reliability today. Many of those plants have been retired since 2010, but others have received extensions.

The remaining plants have various deadlines for when they must cease operations, with the soonest being the end of 2023.

Also at issue is the embattled Diablo Canyon nuclear power plant, California’s largest electricity source. The Pacific Gas & Electric-owned plant is scheduled to close in 2025, but the strain on the grid has officials considering the possibility of seeking an extension. Newsom said earlier this spring he would be open to extending the life of the plant. Doing so would also require federal approval.

The International Brotherhood of Electrical Workers 1245, a labor union, sees the energy package as a way to preserve Diablo Canyon, and jobs at the plant.

“The value to 1245 PG&E members at Diablo Canyon is clear — funding to keep the plant open,” the union said of the bill.

Assemblymember Al Muratsuchi (D-Los Angeles) criticized the bill as “crappy” when it came to the floor in late June, describing it as “a rushed, unvetted and fossil-fuel-heavy response” to the state’s need to bolster the grid.

“The state has had over 12 years to procure and bring online renewable energy generation to replace these once through cooling gas power plants,” Muratsuchi said. “Yet, the state has reneged on its promise to shut down these plants, not once, but twice already.”

Not all details of the state’s energy budget are final. Lawmakers still have $3.8 billion to allocate when they return on Aug. 1 for the final stretch of the year.

Creasman, at California Environmental Voters, said she wants lawmakers to set specific guidelines for how and where it will spend the $2.2 billion when they return in August to dole out the remaining money in the budget. Newsom and legislators also need to ensure that this is the last time California has to spend money on fossil fuel, she said.

“Californians deserve to see what the plan is to make sure we’re not in this position again of having to choose between making climate impacts worse or keeping our lights on,” Creasman said. “That’s a false choice.”

Chester County Landfill Converts Methane to Renewable Gas

SECCRA Waga Energy RNG Partnership captures landfill methane with WAGABOX, upgrades biogas to pipeline-quality RNG, enables grid injection, and lowers greenhouse gas emissions, delivering sustainable energy to Chester County homes and businesses.

 

Key Points

A joint project converting landfill methane to RNG with WAGABOX, cutting emissions and supplying local heat.

✅ WAGABOX captures and purifies landfill gas to RNG

✅ Grid injection supplies energy for 4,000+ homes

✅ Cuts methane and greenhouse gas emissions significantly

 

In a significant environmental initiative, the Southeastern Chester County Refuse Authority (SECCRA) has partnered with French energy company Waga Energy to convert methane emissions from its landfill into renewable natural gas (RNG). This collaboration aims to reduce greenhouse gas emissions and provide sustainable energy to the local community, echoing energy efficiency projects in Quebec seen elsewhere.

Understanding the Issue

Landfills are a substantial source of methane emissions, accounting for over 14% of human-induced methane emissions, according to the U.S. Environmental Protection Agency. Methane is a potent greenhouse gas, and issues like SF6 in power equipment further boost warming, trapping more heat in the atmosphere than carbon dioxide, making its reduction crucial in the fight against climate change.

The SECCRA-Waga Energy Partnership

SECCRA, serving approximately 105,000 residents in Chester County, processes between 450 to 500 tons of waste daily. To mitigate methane emissions from its landfill, SECCRA has partnered with Waga Energy to install a WAGABOX unit—a technology designed to capture and convert landfill methane into RNG, while related efforts like electrified LNG in B.C. illustrate sector-wide decarbonization.

How the WAGABOX Technology Works

The WAGABOX system utilizes a proprietary process to extract methane from landfill gas, purify it, and inject it into the natural gas grid. This process not only reduces harmful emissions, as emerging carbon dioxide electricity generation concepts also aim to do, but also produces a renewable energy source that can be used to heat homes and power businesses.

Environmental and Community Benefits

By converting methane into RNG, the project significantly lowers greenhouse gas emissions, supported by DOE funding for carbon capture initiatives, contributing to climate change mitigation. Additionally, the RNG produced is expected to supply energy to heat over 4,000 homes, providing a sustainable energy source for the local community.

Broader Implications

This initiative aligns with international clean energy cooperation to reduce methane emissions from landfills. Similar projects have been implemented worldwide, demonstrating the effectiveness of converting landfill methane into renewable energy. For instance, Waga Energy has successfully deployed WAGABOX units at various landfills, showcasing the scalability and impact of this technology.

The collaboration between SECCRA and Waga Energy represents a proactive step toward environmental sustainability and energy innovation. By transforming landfill methane into renewable natural gas, the project not only addresses a significant source of greenhouse gas emissions as new EPA power plant rules on carbon capture advance parallel strategies, but also provides a clean energy alternative for the Chester County community.

N.B. Power hits pause on large new electricity customers during crypto review

N.B. Power Crypto Mining Moratorium underscores electricity demand risks from bitcoin mining, straining the energy grid and industrial load capacity in New Brunswick, as a cabinet order prioritizes grid reliability, utility planning, and allocation.

 

Key Points

Official pause on new large-scale crypto mining to protect N.B. Power grid capacity, stability, and reliable supply.

✅ Cabinet order halts new large-scale crypto load requests

✅ Review targets grid reliability, planning, and capacity

✅ Non-crypto industrial customers exempt from prolonged pause

 

N.B. Power says a freeze on servicing new, large-scale industrial customers in the province remains in place over concerns that the cryptocurrency sector's heavy electricity use could be more than the utility can handle.

The Higgs government quietly endorsed the moratorium in a cabinet order in March 2022 and ordered a review of how the sector might affect the reliable electricity supply and broader electricity future planning in the province.

The cabinet order, filed with the Energy and Utilities Board, said N.B. Power had "policy, technical and operational concerns about [its] capacity to service the anticipated additional load demand" from energy-intensive customers such as crypto mines.

It said the utility had received "several new large-scale, short-notice service requests" to supply electricity to crypto mining companies that could put "significant pressure" on the existing electricity supply.

The order, signed by Premier Blaine Higgs, said non-crypto companies shouldn't be subject to the pause for any longer than required for the review, amid shifts in regional plans like the Atlantic Loop that are altering timelines. Ws.

The freeze was ordered months after Taal Distributed Information Technologies Inc. announced plans to establish a 50-megawatt bitcoin mining operation and transaction processing facility in Grand Falls.

A town official said this week that the deal never went ahead.

24 hours a day
The Taal facility would have joined a 70-megawatt bitcoin mine in Grand Falls operated by Hive Blockchain Technologies.

Hive's Bitcoin mine comprises four large warehouses containing thousands of computers running 24 hours a day to earn cryptocurrency units.

The combined annual electricity consumption of the two mines would exceed what could be produced by the small modular nuclear reactor being designed by ARC Clean Energy Canada of Saint John, even as Nova Scotia advances efforts to harness the Bay of Fundy's powerful tides for clean power.

Put another way, the two mines would gobble up more than three months' electricity from N.B. Power's coal-fired Belledune generating station under current operations.

Enel kicks off 90MW Spanish wind build

Enel Green Power España Aragon wind farms advance Spain's renewable energy transition, with 90MW under construction in Teruel, Endesa investment of €88 million, 25-50MW turbines, and 2017 auction-backed capacity enhancing grid integration and clean power.

 

Key Points

They are three Teruel wind projects totaling 90MW, part of Endesa's 2017-awarded plan expanding Spain's clean energy.

✅ 90MW across Sierra Costera I, Allueva, and Sierra Pelarda

✅ €88m invested; 14+7+4 turbines; Endesa-led build in Teruel

✅ Part of 2017 tender: 540MW wind, 339MW solar, nationwide

 

Enel Green Power Espana, part of Enel's wind projects worldwide, has started constructing three wind farms in Aragon, north-east Spain, which are due online by the end of the year.

The projects, all situated in the Teruel province, are worth a total investment of €88 million.

The biggest of the facilities, Sierra Costera I, will have a 50MW and will feature 14 turbines.

The wind farm is spread across the municipalities of Mezquita de Jarque, Fuentes Calientes, Canada Vellida and Rillo.

The Allueva wind facility will feature seven turbines and will exceed 25MW.

Sierra Pelarda, in Fonfria, will have four turbines and a capacity of 15MW, as advances in offshore wind turbine technology continue to push scale elsewhere.

The projects bring the total number of wind farms that Enel Green Power Espana has started building in the Teruel province to six, equal to an overall capacity of 218MW.

Endesa chief executive Jose Bogas said: “These plants mark the acceleration on a new wave of growth in the renewable energy space that Endesa is committed to pursue in the next years, driving the energy transition in Spain.”

The six wind farms under construction in Teruel are part of the 540MW that Enel Green Power Espana was awarded in the Spanish government's renewable energy tender held in May 2017.

In Aragon, the company will invest around €434 million euros, reflecting broader European wind power investment trends in recent years, to build 13 wind farms with a total installed capacity of more than 380MW.

The remaining 160MW of wind capacity will be located in Andalusia, Castile-Leon, Castile La Mancha and Galicia, even as some Spanish turbine factories closed during pandemic restrictions.

Enel Green Power Espana was also awarded 339MW of solar capacity in the Spanish government's auction held in July 2017, while other Spanish developers advance CSP projects abroad in markets like Chile.

Once all wind and solar under the 2017 tender are complete they will boost the company’s capacity by around 52%.
