NOTICE DATE: August 16, 2011
NOTICE TYPE: W-A081611-01 Operations
SHORT DESCRIPTION: RMR Agreements signed with Garland Power & Light and NRG Texas Power LLC
INTENDED AUDIENCE: ERCOT Market Participants
DAYS AFFECTED: August 16 – October 31, 2011
LONG DESCRIPTION:
As indicated at the August 16, 2011, ERCOT Board of Directors meeting, Electric Reliability Council of Texas, Inc. (ERCOT) has signed Reliability Must Run (RMR) Agreements with two Resource Entities
to return Mothballed Generation Resources to service as soon as practicable to mitigate capacity shortages during the extreme heat and drought conditions impacting the ERCOT Region.
Garland Power & Light (Garland) has agreed to bring back Spencer Units 4 and 5 with approximately 122 MW of total capacity. NRG Texas Power LLC (NRG)
has agreed to bring back SR Bertron Units 1 and 2 with approximately 292 MW of total capacity.
ERCOT will take all necessary steps in accordance with the Protocols. ERCOT plans to minimize the use of these RMR Units in order to allow market solutions
to meet demand needs first. In conditions where ERCOT indicates a capacity shortage with no available market Resources, then these RMR Resources will be committed under Reliability Unit Commitment (RUC) to ensure system reliability.
These RMR Agreements will terminate on October 31, 2011, unless extended by ERCOT.
ADDITIONAL INFORMATION: ERCOT will post the Notification of Change
of Generation Resource Designation form and RMR Agreement for all RMR Units
on the Market Information System (MIS) Secure Area on the Grid/Generation page under Reliability Must Run at
https://mis.ercot.com/pps/tibco/mis/Pages/Grid+Information/Generation.
An ERCOT digital certificate is required to access the MIS.
