Substantive Rule 25.507(g) requires ERCOT to report publicly the number of Emergency Reserve Service (ERS) MW procured per Time Period, the number of Resources providing the service and the projected total cost of the service prior to the start of the Standard

The results of the procurement of ERS for the Standard Contract Term of June 1, 2012, to September 30, 2012, are as follows:

Self-Provided capacity is included in the above tables, valued at the weighted average price per Time Period. Total maximum
projected cost of ERS for this Standard Contract Term, including projected credits for ERS Self-Provision, is $11,621,720.72. All numbers are subject to negative adjustment based on ERS Resources’ availability and performance factors, which are calculated
after the end of the Standard Contract Term.
Pursuant to Nodal Protocols Section 6.5.9.4.2(2)(a)(iii), ERCOT has the authority to establish two deployment groups of ERS
Resources if the capacity procured exceeds 500 MW in an ERS Time Period. Although the Business Hours 1 procured capacity of 513 MW for this cycle meets this criterion, ERCOT has elected not to create separate groups during this Contract Term, based on the
fact that the threshold was met in only one Time Period and the capacity procured exceeds the threshold by only a small amount.
