This Operating Guide Revision Request (OGRR) allows for participation of Distributed Energy Resources (DERs) in Responsive Reserve Service (RRS) on an equivalent basis with synchronous condenser fast-response hydro.
Reason:
This OGRR allows DERs to participate in RRS markets subject to the restrictions provided in the Protocols and Operating Guides, equivalent to hydro unit(s) operating in the synchronous condenser fast response mode, as recommended by ERCOT in the 8/20/09 ERCOT Comments (paragraph (1)(b)) to PRR825, Distributed Energy Resource Participation in Responsive Reserve Service Markets. More specifically, DER would have a 59.9 Hz trigger level, positive generation in four (4) seconds and full output in ten (10) seconds. The associated PRR838, Fast Response Distributed Energy Resource (DER), defines DER and designates it as an RRS category in Protocol Section 6.5.4.
