Battery Energy Storage

The Battery Energy Storage initiative addresses integration of battery Energy Storage Resources into the ERCOT System.  This section contains work products from the Battery Energy Storage Task Force (BESTF) which is responsible for developing policy recommendations. The Battery Energy Storage Task Force (BESTF) is a non-voting body that reports directly to the ERCOT Technical Advisory Committee (TAC) and provides recommendations to TAC.  BESTF will develop policy recommendations for consideration by TAC relating to the integration of battery Energy Storage Resources into the ERCOT System. BESTF will consider operational and market design policies that may be implemented using a two-step approach: (1) rules that can be implemented in the short-term to integrate battery Energy Storage Resources under the "combination model" structure, and (2) rules that can be implemented on a longer timeline to integrate battery Energy Storage Resources under a "single model" structure.
