Federal Energy Regulatory Commission
• FERC issued a landmark order on Oct. 21 that will greatly enhance the economic benefits water agencies and others receive under the State’s Feed-In Tariff program.
• The ruling paves the way for the California Public Utilities Commission (PUC) to increase rates that third-party power generators receive for the energy they sell back to the grid from the current 8 cents per kilowatt-hour (kWh) to the 16 cents to 20 cents that utilities receive for comparable energy under the State’s Renewable Portfolio Standard.
