The Virginia State Corporation Commission approved Sustainable Power Group’s application to construct the Spotsylvania Solar Energy Center, set to be Virginia’s largest solar project. The solar farm, planned for western Spotsylvania County, will sell its output to the wholesale market operated by PJM Interconnection LLC. In March, Microsoft Corp. announced a contract to buy 315 megawatts of the project’s capacity, marking an important step towards the software company’s goal of powering 60 percent of its data centers with renewable resources by 2020. The first phase of the project is scheduled to go into service by July 2019. Sustainable Power is owned by AES Corp. and the Alberta Investment Management Corp.
