SCR735 RRS Calculation for Hydro Units in Synchronous Condenser Mode
ReasonCurrently the ERCOT market clearing engine does not account for hydro units that are operating in synchronous condenser mode when calculating a QSE™s available capacity to meet its Responsive Reserve Obligation. This issue results in failure notifications from the Resource Plan Validation study and shows an RRS deficiency in the Hour-Ahead Study. Furthermore, the market clearing engine calculation is not consistent with the reserve modeling calculation used in Real Time, which does account for the status of the unit in synchronous condenser mode.

Summary
The ERCOT market clearing engine, which performs Resource Plan Validation and the Hour-Ahead Study, and clears the Real Time Balancing Energy Market, should be modified to allocate Responsive Reserve Service according to the ERCOT Operating Guides to hydro units operating in synchronous condenser mode.
