Because the February through May 2011 EILS Contract Period obligation was exhausted on February 3, 2011, at 10:00 CPT, this EILS Contract Period was settled-and will be resettled-according to two periods. Using two settlement periods ensures that the EILS charges are assessed using only the Load Ratio Share data relative to the periods during which the service could actually be provided. The two periods are as follows:

1)    February 1 - 10:00 CPT on February 3, 2011

2)    April 1 - May 31, 2011.

Pursuant to Protocols Section 6.6.11.2(1), "For the resettlement of the EILS Contract Period as described in item (2) of Section 9.14.5, the LRS will be calculated using the True-up Load for each Operating Day in the EILS Contract Period. True-up Load will be calculated according to the timing specified in item (2) of Section 9.5.8, RTM True-Up Statement."

The True-Up ERCOT Load used to calculate EILS charges for the February 1 - 3, 2011, period is as follows:

Group 1 - Time Period

Business Hours 1 (HE 0900-1300)*
