The Financial Post reports in its Wednesday edition that Alphabet has reached a $3-billion (U.S.) deal to access hydroelectric power from Brookfield's renewables arm, part of a race to secure clean energy to meet booming power demand from cloud computing and artificial intelligence. A Financial Times dispatch says two 20-year power purchase agreements, the largest of their kind for hydro power, will first deliver up to a total of 670 megawatts of power from Brookfield's Holtwood and Safe Harbor facilities in Pennsylvania, which the asset manager acquired in 2015 and 2014, respectively. Google will have the option of procuring power from a total of three gigawatts worth of hydroelectric assets through future projects, including upgrading hydro installations. Power from these facilities that is not required by the tech giant will be funnelled to electricity markets across America. The deal comes as tech companies rush to meet AI's intense energy demands while easing concerns about the environmental impact of the technology. While data centre developers have struck similar deals to finance wind and solar farms, the focus on hydro power reflects a political and regulatory shift toward "firm" sources of renewable energy.
