Largest hydroelectric corporate power agreement to date: Google will access up to 3,000 MW of carbon-free hydroelectric power across the U.S., starting with 670 MW from two facilities in Pennsylvania.
$3B in initial 20-year PPAs signed: Google and Brookfield commit to long-term clean power purchases, while Google also plans $25B in regional data center investments.
Supports AI-driven energy demand: The agreement reinforces Google’s strategy to secure 24/7 carbon-free energy amid surging power needs from data centers and AI.
Google has announced the world’s largest corporate clean energy agreement for hydroelectric power, signing a landmark deal with Brookfield Asset Management to secure up to 3,000 megawatts (MW) of carbon-free electricity across the United States.
The agreement begins with two Pennsylvania-based hydropower facilities—Holtwood and Safe Harbor—totaling 670 MW under initial 20-year power purchase agreements (PPAs) valued at $3 billion. These sites will be relicensed and upgraded to extend their operational lifespan.
“This collaboration with Brookfield is a significant step forward, ensuring clean energy supply in the PJM region where we operate,” said Amanda Peterson Corio, Head of Data Center Energy at Google. “Hydropower is a proven, low-cost technology, offering dependable, homegrown, carbon-free electricity that creates jobs and builds a stronger grid for all.”
The Hydro Framework Agreement (HFA) enables Google to procure power from hydropower assets that Brookfield will relicense, overhaul, or enhance. While initially focused on the PJM (mid-Atlantic) and MISO (mid-continent) markets, the framework provides flexibility to expand to other regions in the U.S.
The move aligns with Google’s commitment to sourcing 24/7 carbon-free energy for its operations and comes as the company prepares to invest $25 billion in new data centers across Pennsylvania and neighboring states, according to Semafor. These data centers will support energy-intensive workloads such as artificial intelligence and cloud computing—sectors driving U.S. electricity demand to record highs.

Connor Teskey, President of Brookfield Asset Management, emphasized hydropower’s role in supporting this growth:
“Our partnership with Google demonstrates the critical role that hydropower can play in helping hyperscale customers meet their energy goals. Delivering power at scale and from a range of sources will be required to meet the growing electricity demands from digitalization and artificial intelligence.”
The agreement builds on Google’s recent series of first-of-its-kind power deals, including for geothermal and advanced nuclear energy. Google is also collaborating with grid operator PJM Interconnection to deploy AI tools aimed at accelerating the connection of new clean power projects to the grid.
This announcement is expected to feature at an AI summit in Pittsburgh, where Alphabet President and CIO Ruth Porat will speak. Former U.S. President Donald Trump is also scheduled to attend the event, where $70 billion in AI and energy investments are anticipated.
