Reactive Power Requirements for Non-Synchronous Generation

Order 807 addressed the compensation of non-synchronous generators — primarily inverter-based wind and solar resources — for providing reactive power service to maintain grid voltage stability. As the power system has transitioned away from conventional synchronous generators, FERC recognized the need to establish clear rules for how inverter-based resources are compensated for the reactive power they provide. The order required transmission providers to compensate non-synchronous generators for reactive power provided within their required operating range, using a standard methodology for calculating reactive power capability and associated revenue requirements.
