Pay for performance regulation
FERC Order No. 755 required that the ISO modify the compensation mechanism for regulation to include a performance payment with an accuracy adjustment in addition to the existing capacity payment. The ISO has FERC approval of the proposed tariff modifications, and is conducting a one year evaluation of the methodology for calculating mileage accuracy and assessing whether the minimum performance standard and any additional items should be revised.
Effective May 1, 2013 the ISO implemented functionality to comply with FERC Order 755 for compensation of frequency regulation in organized wholesale power markets. The ISO developed a two-part structure to establish the prices for regulation capacity and mileage, which is a performance based payment. Resources that receive regulation capacity awards must also receive a mileage award and vice versa. The ISO measures a resource’s actual performance in how well it responds to a dispatch signal.
