FERC v. Bluebonnet State PUC on Battery Storage.

What did the FERC Order do? FERC requires grid operators to establish a set of rules to incorporate batteries into the wholesale electricity market with 4 requirements:

• Allow storage to provide energy, capacity and ancillary services;
• Allow storage to set wholesale market prices as a buyer or seller of electricity;
• Respect the operational characteristics of storage, such as discharge duration or state-of-charge requirements, and;
• Set a minimum size for market participation not more than 100 kW. 

What has Texas PUC done? In January it began the rule making process for battery storage integration into the state’s competitive electric market
