Notice of Staff Issue Resolution
Workshop for the
CPV Sentinel Energy Project
(07-AFC-3)

The California Energy Commission staff will conduct an Issue Resolution workshop for the CPV Sentinel Energy Project. The purpose is to discuss the applicant's response to staff's letter of December 21, 2007 regarding alternatives to the project's proposed wet cooling system and the applicant's options for responses to staff's data requests. A copy of this letter can be found on the Energy Commission's website under: http://www.energy.ca.gov/sitingcases/sentinel/documents/2007-12-21_RESPONSE_TO_11-27_LETTER_FROM_APPLICANT.PDF

All interested agencies and members of the public are invited to participate. The workshop will be held:

THURSDAY, JANUARY 24, 2008
1:00 to 4:00 p.m.

Background

On June 25, 2007, CPV Sentinel, LLC submitted an Application for Certification (AFC) to the California Energy Commission to construct and operate a simple-cycle (peaking) power plant. The Sentinel project is a proposed nominally rated 850 megawatt (MW) electrical generating facility that would encompass 37 acres of land situated within unincorporated Riverside County, California, adjacent to the Palm Springs northern city limits. The proposed project consists of eight natural gas-fired General Electric (GE) LMS100 combustion turbine generators operating in simple-cycle mode. The project has a contract with Southern California Edison for 550 megawatts (MW) and would supply quick-start peaking capacity, energy, and ancillary services into the California Independent System Operator's Los Angeles Basin Local Capacity Requirement Area.

Purpose

The Energy Commission staff is currently analyzing CPV Sentinel, LLC's AFC for the proposed development of the CPV Sentinel Energy Center (Sentinel). The Energy Commission has adopted a policy regarding the use of fresh water in association with power plants. Specifically, the Energy Commission's 2003 Integrated Energy Policy Report (IEPR) states: the Energy Commission will approve the use of fresh water for cooling purposes by power plants which it licenses only where alternative cooling technologies are shown to be "environmentally undesirable" or "economically unsound." Based upon what we know today and stated in the December 21, 2007 letter to the applicant, staff does not believe the proposed CPV Sentinel project complies with the State Water Resources Control Board (SWRCB) and the Energy Commission's IEPR policy regarding the use of fresh inland water for power plant cooling. Further, staff is in the process of assessing whether the project would cause a significant adverse impact to water resources in the region associated with depleting an already overdrafted water basin.

Staff is seeking to evaluate project alternatives that would mitigate a potential significant environmental impact and comply with Laws, Ordinances, Regulations and Standards (LORS). Options that do not require the use of fresh inland water may include:

  • Use of the Desert Hot Springs Sub-basin groundwater as a source of lower quality, high total dissolved solids (TDS) groundwater.
  • Use of a different inlet and turbine inter-cooling method, such as a mechanical air-chiller with air cooling, instead of using a wet cooling tower. Public Participation.
