Alphabet-owned Google has struck a $3 billion deal with Brookfield Asset Management for electricity generated from two hydropower facilities in Pennsylvania. The tech giant will also invest $25 billion in data centers across Pennsylvania and neighboring states over the next two years, Semafor reported on Tuesday.

Asset management firm Blackstone plans a $25 billion investment in data centers and energy infrastructure in Pennsylvania, its President and Chief Operating Officer Jon Gray told a panel at the summit.
