ERCOT adds new service to support grid reliability
ERCOT has launched the ERCOT Contingency Reserve Service (ECRS), a new daily procured ancillary service.
As energy demand continues to grow in Texas, ERCOT said that adding ECRS will support grid reliability and mitigate real-time operational issues to keep supply and demand balanced. ECRS will complement and provide support to the four procured ancillary services ERCOT currently uses: Regulation Up, Regulation Down, Responsive Reserve Service and Non-Spin Reserve Service. ECRS, which was launched June 12, is the first daily procured ancillary service introduced to the ERCOT market in more than 20 years.
The move comes as ERCOT implements the final piece of a 2019 decision to address the increased levels of intermittent renewable resources on the grid. Nodal Protocol Revision Request (NPRR) No. 863 was approved in February 2019 with the objective to stabilize frequency and reduce inertia on the system. As part of the same decision, ERCOT approved and previously completed changes to the existing Responsive Reserve Service (RRS).
