Google has signed a deal to secure up to 3 gigawatts of hydropower in the United States through a long-term agreement with Brookfield Asset Management.
The agreement marks the largest corporate clean energy purchase for hydroelectric power to date.
The deal includes 20-year power purchase agreements worth $3 billion from two hydropower plants in Pennsylvania, which Brookfield owns and operates. As part of the arrangement, the facilities will be upgraded and relicensed.
Google said it aims to expand the agreement beyond these sites to other areas in the Mid-Atlantic and Midwest.
Google also plans to invest $25 billion in data centers across Pennsylvania and nearby states over the next two years, according to a report published Tuesday. The company said the investment supports the growing demand for computing power, especially from artificial intelligence and cloud services, which are increasing electricity use across the country.
Ruth Porat, president and chief investment officer at Alphabet, is expected to speak about the announcement at an AI summit in Pittsburgh. U.S. President Donald Trump is scheduled to attend the event, where a total of $70 billion in AI and energy investments may be announced.
Amanda Peterson Corio, Google’s head of data center energy, said the deal ensures a clean energy supply in the PJM region, which operates the largest electricity grid in the United States.
Over the past year, Google has signed several first-time power agreements, including deals for geothermal and advanced nuclear energy. It is also working with PJM Interconnection to use artificial intelligence to speed up the connection of new energy projects to the grid.
