Interconnect worked out for 558-MW Clear Springs peaker in Texas

Filed with the Texas Public Utility Commission on June 3 was a Standard Generation Interconnection Agreement between LCRA Transmission Services Corp. and Navasota South Peakers Operating Company II LLC for the gas-fired Clear Springs Energy Center project.

The project’s Point of Interconnection will be at the existing LCRA TSC Clear Springs Substation located in Guadalupe County, Texas.

Said the SGIA: “The Plant is a simple cycle gas generation facility with one Point of Interconnection to the grid. The Plant rating is expected to be approximately 558 MW of AC power at the Point of Interconnection.” It is made up of three 186-MW General Electric 7FA.04 gas combustion turbine units.

The project’s scheduled commercial operation date under the SGIA is June 1, 2018.

A project contact listed in the SGIA is: Navasota South Peakers Operating Company II LLC, Attn: Mark Breen, 1401 McKinney Street, Suite 1800, Houston, TX 77010, 24 Hour Telephone: (713) 485-8690,

Says the website of power project developer Navasota Energy: “The Clear Springs Energy Center is a 579 MW simple cycle gas fired electric generating facility located in Guadalupe County, TX. The Facility will consist of three highly-efficient, super clean 193 MW gas turbines with AGC, evaporative cooling and dry low NOx burners. Upon completion, this Facility will support peak energy demands in the South Zone of ERCOT. The Facility is anticipated to be operated in the 2017-2018 timeframe.”

Quantum Utility Generation LLC (QUG) had announced on April 12 that all three of the sites in its advanced development portfolio of natural gas-fired peaker projects involving Navasota Energy Services LLC have received their PSD air permits and GHG air permits and are construction-ready.

Navasota Energy Generation Holdings LLC (‘NEGH’), whose members are affiliates of QUG and Navasota, respectively, is excited about the opportunity to advance its marketing efforts for our fully-permitted sites in ERCOT. We see a growing need in ERCOT for the addition of highly-efficient natural gas-fired peaking capacity to support the integration of large-scale renewable resources as well as to offer customers cost-effective protection from the price volatility that has dramatically impacted this market in the past and is expected to increase in the future,” said Sean O’Donnell, President of both QUG and NEGH.

The 1,885-MW NEGH portfolio consists of three advanced-stage projects and one project already in construction:

  • the Van Alstyne Energy Center located in Grayson County, Texas;
  • the Union Valley Energy Center located in Wilson County, Texas;
  • the Clear Springs Energy Center located in Guadalupe County, Texas; and
  • the 121-MW Friendswood Energy Center under construction in Houston, Texas.

The in-development projects could be available for commercial operations beginning in the 2017-2018 time range, the company noted.
