Along with Avangrid, NREL, and GE, the California Independent System Operator (CAISO) tested the ability of a 131.1 MW wind farm to provide ancillary grid services. CAISO reported results from a similar pilot at an inverter-controlled solar power plant in 2018. The ISO's most recent report found that the wind farm's inverter-based smart controller could provide balancing or regulation up and down, voltage regulation control, active power control through ramping capability, and frequency response. While this means existing assets with minimal upgrades could find new revenue streams, clients should realize that current incentives and markets for renewables would need to be modified to reward ancillary services and not just energy production.
