USA, California: Golden State Independent System Operator to Use Flexible Ramping Product to Control Supply of Renewable Energy

FERC approves CAISO ramping product, rejecting calls to make it biddable (Utility Dive)

The Federal Energy Regulatory Commission (FERC) this week approved a flexible ramping product proposed by the California Independent System Operator (CAISO).

The product is designed to help CAISO with the growing amount of renewable resources on its grid and the uncertainty it causes in its day-ahead and real-time electricity market. FERC rejected calls from some distributed energy providers to make the ramping product biddable.

The operator's existing frequency regulation service addresses some of those grid issues, but CAISO opted for a new product to preserve capacity for regulation service and because using frequency regulation when a ramping service could be used could distort regulation pricing.

There will be a GRC Fieldtrip to the headquarters of CAISO from the GRC Annual Meeting & GEA Geothermal Energy Expo, October 23-26, Sacramento, California.
