California ISO - Documents By Group

Outcome
Effective October 1, 2016 the ISO implemented solutions that: (1) distinguish between residual imbalance energy due to the forecast changes and energy due to economic dispatch in settlements; (2) limit the application of the persistent deviation metric to residual imbalance energy where there were concerns of a forecast error triggering the metric, (3) remove the metric for residual imbalance energy for economically bidding variable energy resources; and (4) correct the boundary condition of the day-ahead metered energy adjustment factor for certain Pmin scenarios. — Implemented: Oct. 1, 2016; FERC approval: July 20, 2016; Tariff amendment filing: May 25, 2016 ; Board of Governors approval: July 16, 2015
