The Woodlands-based Plus Power has collected an estimated $98 million tax equity investment for its 200-megawatt Ebony Energy Storage facility near San Antonio.

Plus Power says the investment from Solana Beach, California-based Greenprint Capital Management will help stabilize the Energy Reliability Council of Texas (ERCOT) power system “during dynamic summer demand and cold winter storms while helping to integrate more renewable energy into the grid.”

The storage facility, being built on 13 acres in Comal County, is scheduled to come online this spring.

Peter DeFazio, managing director of Greenprint, calls Plus Power “a first mover” among owner-operators of standalone battery energy storage facilities in the U.S. Plus Power owns a portfolio of large-scale lithium-ion battery systems in more than 25 states and Canada.

“As the state and the country experience increasingly extreme temperatures, we are proud that our projects can provide grid services that will help ERCOT increase reliability and meet abnormally high demand,” says Josh Goldstein, chief financial officer of Plus Power.

By this summer, Plus Power expects to be operating four storage plants in the ERCOT market with 800 megawatts of total capacity.

Plus Power announced in 2023 that it completed a $1.8 billion financing for Ebony and four other projects in Texas and Arizona. The financing included $196 million in construction and term financing for the Comal County project.

Constellation and Calpine's $26B clean energy megadeal clears final regulatory hurdle

big deal

Baltimore-based nuclear power company Constellation Energy Corp. received final regulatory clearance this month to acquire Houston-based Calpine Corp. for a net purchase price of $26.6 billion.

The acquisition has the potential to create America’s “largest clean energy provider,” the companies reported when the deal was first announced in January.

The Department of Justice approved the acquisition contingent on Calpine divesting several assets, including one in the Houston area.

The company agreed to divest the Jack Fusco Energy Center natural gas-fired combined cycle facility in Richmond, Texas; four generating assets in the Mid-Atlantic region; and other natural gas plants in Pennsylvania and Corpus Christi, Texas.

The Federal Energy Regulatory Commission, the Public Utility Commission of Texas and the New York Public Service Commission previously approved the deal. The companies can move toward closing the acquisition once the court finalizes the stipulation and order.

"We are very pleased to reach a settlement that allows us to bring together two magnificent companies to create a new Constellation with unprecedented scale, talent and capability to better serve our customers and communities while building the foundation for America’s next great era of growth and innovation," Joe Dominguez, president and CEO of Constellation, said in a news release. "We thank the Department for its professionalism and tireless work reviewing this transaction through these many months. It’s now time for us to complete the transaction, welcome our new colleagues from Calpine, and together begin our journey to light the way to a brilliant tomorrow for all."

Andrew Novotny, CEO of Calpine, will continue to lead the Calpine business and Constellation's fleet of natural gas, hydro, solar and wind generation, according to the company. He will report to Dominguez and also serve as senior executive vice president of Constellation Power Operations.

Constellation is considered one of the top clean energy producers in the U.S. Earlier this month, the company was approved to receive a $1 billion loan from the Department of Energy's Energy Dominance Financing Program to restart its 835-megawatt nuclear reactor in Pennsylvania known as Crane Clean Energy Center.

"Work to restart the reactor comes at a time of unprecedented electric demand growth from electrification and the new data centers needed to support a growing digital economy and to help America win the AI race," a news release from the company reads. "Crane will support grid stability by delivering reliable, around-the-clock electric supply."

States brace for Trump's push to make oil drilling cheap again

Energy news

A Republican push to make drilling cheaper on federal land is creating new fiscal pressure for states that depend on oil and gas revenue, most notably in New Mexico as it expands early childhood education and saves for the future.

The shift stems from the sweeping law President Donald Trump signed in July that rolls back the minimum federal royalty rate to 12.5%. That rate — the share of production value companies must pay to the government — held steady for a century under the 1920 Mineral Leasing Act. It was raised to 16.7% under the Biden administration in 2022.

Trump and Republicans in Congress say the rate reset will boost energy production, jobs and affordability as the administration clears the way for expanded drilling and mining on public lands.

States receive nearly half the money collected through federal royalties, depending on where production takes place. The environment and economics research group Resources for the Future estimates a roughly $6 billion drop in collections over the coming decade.

The stakes are highest in New Mexico, the largest recipient of federal mineral lease payments. The state could could forgo $1.7 billion by 2035 and as much as $5.1 billion by 2050, according to calculations by economist Brian Prest at Resources for the Future.

More than one-third of the general fund budget in the Democratically-led state is tied to the oil and gas industry.

“New Mexico’s impact is way bigger than Wyoming or Colorado or North Dakota,” Prest said, “and that’s just because that’s where the action is on new development.”

The effects will unfold gradually, since federal leases allow a 10-year window to begin drilling and production. Still, state officials say they're already prepping for leaner years.

“It all hurts when you’re losing revenues," said Democratic state Sen. George Muñoz of Gallup, who said lawmakers still hope to invest more in mental health care and support Medicaid, even if federal royalty payments decline. “We’ve learned that until the chicken’s got feathers, we’re not even looking at it."

The higher federal royalty rate was in place for roughly three years while leasing activity was muted, Prest said. New Mexico budget forecasters never tallied the additional income.

New Mexico's nest-egg strategy

A nearly five-fold surge in local oil production since 2017 on federal and state land in New Mexico delivered a financial windfall for state government, helping fund higher teacher salaries, tuition-free college, universal free school meals and more.

The state set aside billions of dollars in investment trusts for future spending in case the world’s thirst for oil falters, including a early childhood education fund to help expand preschool, child care subsidies and home wellness visits for pregnancies and infants.

The state's investment nest egg has grown to $64 billion, second only to Alaska's Permanent Fund. Earnings from the trusts are New Mexico's second-biggest source for general fund spending.

That sturdy financial footing shaped a defiant response to this year’s federal government shutdown, when lawmakers voted to subsidize the state’s Affordable Care Act exchange, cover food assistance and backfill cuts to public broadcasting.

But lawmakers reviewing state finances learned that predictable income fell 1.6% — the first contraction since the start of the COVID-19 pandemic.

Muñoz said matters would be worse if the state had not raised its own royalty rates this year to 25%, from 20%, for new leases on prime oil and gas tracts, while ending a sales moratorium, under legislation he co-sponsored this year.

Encouraged in Alaska

After New Mexico, the states receiving the most federal oil and gas royalties are Wyoming, Louisiana, North Dakota and Texas.

Texas, the nation’s top oil producer, shares the bountiful Permian Basin with New Mexico but has far less federal land and therefore less exposure to changes in royalty policy.

In Alaska, state officials say they are encouraged by the royalty cut, seeing potential for increased development in places like the National Petroleum Reserve-Alaska, where the massive Willow project — approved in 2023 and now under development — is viewed by some as a catalyst for further activity. The reserve is expected to hold its first lease sales since 2019.

“If reduced federal royalty rates stimulate new leasing, exploration and production, that also could increase other kinds of revenue,” said Lorraine Henry, a spokesperson for Alaska’s Department of Natural Resources.

In North Dakota, federal royalties are split evenly between the state and county governments where drilling occurs. State Office of Management and Budget Director Joe Morrissette said the industry’s future remains difficult to forecast.

“There are so many variables, including timing, price, availability of desirable tracts, and federal policies regarding exploration activities,” Morrissette said.
