Oncor Seeks to Increase Curtailable Load by 50 MW, Citing ERCOT Reserve Margin

Oncor Electric Delivery petitioned the Public Utility Commission of Texas for a good cause exception order to allow it to procure another 50 MW of curtailable load for the summer of 2012 (Docket 40123).
The load would be in addition to the 50 MW Oncor is currently authorized to procure under its Commercial Load Management Program, which is part of its suite of programs to meet energy efficiency goals.
Oncor proposed the additional curtailable load because, "ERCOT has recently advised the Commission that reserve margins for the 2012 summer peak period may not be adequate to maintain reliable electric service to meet the needs of all Texans."
Oncor sought cost recovery of the additional 50 MW via its Energy Efficiency Cost Recovery Factor charged to REPs, as established in the EECRF proceeding in 2013, or similar proceeding.
The costs associated with curtailing the additional 50 MW of commercial load shall be allocated to all rate classes on the basis of the actual 2012 4CP demand because the additional curtailable load serves a reliability benefit to Oncor's entire system, Oncor proposed.
Oncor anticipates that the program costs to obtain an additional 50 MW of commercial load available for curtailment for the 2012 summer peak period will not exceed $3 million.
While the new curtailable load would be similar to the load procured under the energy efficiency program, Oncor said that the new procurement is not being undertaken to meet the energy efficiency standards, and thus should not be governed by the energy efficiency substantive rules. Notwithstanding, Oncor still recommends use of the EECRF for cost recovery, for administrative convenience.
Oncor requested approval by the March 7, 2012 open meeting to allow it to begin outreach for the new program by March 28, 2012, which is the date Oncor said outreach must begin to ensure load can be enrolled and prepared for the summer.
"Oncor's activities to address the issues relating to the 2012 summer peak period would include aggressive recruitment of aggregators and REPs that could identify and sponsor individual CLM [Commercial Load Management] Program participants," Oncor reported.
Oncor also said that it intends to oversubscribe the Commercial Load Management Program by up to 20 MW over the combined 100 MW goal (i.e., 50 MW approved in Docket No. 39375 as part of the energy efficiency program and an additional 50 MW to address the reliability issue regarding the 2012 summer peak period) to provide the best chance of achieving the goals.
