Microsoft has announced a power purchase agreement (PPA) with Constellation to restart an 835 megawatt (MW) nuclear facility in Pennsylvania that was retired in 2019. This move is part of Microsoft's commitment to becoming a carbon negative company by 2030 and will provide a significant supply of carbon-free electricity to the PJM power grid. The company is also working on various other projects to accelerate the energy transition, including a five-year global agreement with Brookfield Renewable Partners for the development of over 10.5 gigawatts of new renewable energy capacity and a five-year framework agreement with Pivot Energy to develop up to 500 MW of community-scale solar energy projects across the US. The announcement was made on September 23, 2024.
