Alphabet's Google will invest $25 billion in data center and artificial intelligence infrastructure over the next two years in states across the biggest electric grid in the U.S., the technology company said Tuesday.

Google will also spend $3 billion to modernize two hydropower plants in Pennsylvania to help meet the growing power demand from data centers and AI in the region, according to the company.

The refurbishment of the Pennsylvania plants is part of broader a framework agreement that Google signed with Brookfield Asset Management to purchase 3,000 megawatts of hydroelectric power across the U.S.

Google's investments in the region comes as the PJM Interconnection is struggling to keep up with rising electricity demand from data centers and industry. PJM is the biggest electric grid in the nation, covering 13 states across the mid-Atlantic and parts of the Midwest and South. It includes the world's largest data center market in northern Virginia.

President Donald Trump, White House Cabinet officials, tech and energy executives are meeting at Carnegie Mellon University in Pittsburgh on Tuesday to discuss AI investment in Pennsylvania.
