Google has agreed to secure as much as 3GW of US hydropower in the world's largest corporate clean power pact for hydroelectricity, the company said on Tuesday, as big tech pursues the expansion of energy-hungry datacenters. The deal between Google and Brookfield Asset Management includes initial 20-year power purchase agreements, totaling 3bn, for electricity generated from two hydropower facilities in Pennsylvania. The tech giant will also invest 25bn in datacenters across Pennsylvania and neighboring states over the next two years, Semafor reported on Tuesday. The technology industry is intensifying the hunt for huge amounts of clean electricity to power datacenters needed for artificial intelligence and cloud computing, which has driven US power consumption to record highs after nearly two decades of stagnation. Ruth Porat, president and chief investment officer at Google parent company Alphabet, discussed the news at an AI summit in Pittsburgh.
