On September 17, FERC issued Order 2222, directing ISOs/RTOs to open their markets to participation by aggregated distributed energy resources (DERs). This Order may have broad implications for RTOs, states, utilities, service providers, and customers, ranging from technical, to jurisdictional, to financial, to operational. This interesting and timely discussion will provide perspectives on the Order from an Investor Owned Utility, Electric Cooperatives, a State Coalition, and a Service Provider.
