Major power generation companies have announced over $50 billion in acquisitions during 2025, driven by surging electricity demand from data centers and artificial intelligence computing facilities.
Largest Transactions
Constellation-Calpine: $16.4 Billion
Constellation Energy, the nation’s largest nuclear power plant operator, agreed in January 2025 to acquire Calpine for $16.4 billion. Texas regulators approved the merger in June 2025, though federal and New York approvals are still pending.
NRG Energy-LS Power: $12 Billion
NRG Energy announced in May 2025 it would acquire LS Power’s generation portfolio for approximately $12 billion including debt. The deal includes 18 natural gas power plants with combined capacity of 13 gigawatts—enough to power approximately 10.4 million homes.
“We are in the early stages of a power demand supercycle, and we are excited to lead the way with reliable energy solutions,” said Larry Coben, NRG CEO.
NRG shares hit all-time highs following the announcement, soaring over 24 percent.
Blackstone-TXNM Energy: $11.5 Billion
Blackstone Infrastructure agreed in May 2025 to acquire New Mexico utility owner TXNM Energy for $11.5 billion including debt. The all-cash deal valued TXNM at $61.25 per share, representing approximately a 15 percent premium.
Blackstone is investing an additional $400 million through purchase of newly issued TXNM shares to support the utility’s growth plans.
Vistra-Lotus Infrastructure: $1.9 Billion
Vistra announced in May 2025 it would acquire seven natural gas generation facilities from Lotus Infrastructure Partners for $1.9 billion. The facilities have combined capacity of nearly 2,600 megawatts.
Market Drivers
The U.S. Energy Information Administration projects electricity consumption will reach record levels in 2025 and 2026, driven by surging demand from data centers supporting artificial intelligence operations, cryptocurrency mining, and general economic growth.
After two decades of relatively flat power demand, U.S. electricity consumption is expanding rapidly. Companies are betting that data center growth and overall electrification of the economy will sustain increased power demand for years.
Texas Focus
Several transactions have particular relevance to Texas:
- NRG Energy separately announced in March 2025 it would acquire 738 megawatts of natural gas generation in Texas
- The NRG-LS Power deal significantly expands NRG’s portfolio in the PJM power market serving the Mid-Atlantic and Midwest, but NRG remains one of the largest power generators in Texas
- Data center developers are rushing to secure long-term power purchase agreements with generation companies
NRG reported in its third quarter 2025 earnings that it had “expanded long-term retail power agreements for data centers with existing customer to 445 MW.”
The wave of consolidation reflects expectations that natural gas generation will remain crucial to meeting baseload and peak electricity demand as intermittent renewable energy sources like solar and wind continue expanding.
