Entergy Texas pursues up-to-1,000-MW Lewis Creek power project

The Entergy Texas Inc. (ETI) subsidiary of Entergy Corp. (NYSE: ETR) is aiming to build its own gas-fired power plant at the Lewis Creek site in Texas following rejection of outside bids from a request for proposals (RFP) issued last year.

Said a brief April 28 notice on the Entergy website: “Please be advised that Entergy Services, Inc., acting under the oversight of the Independent Monitor, has concluded its economic evaluation of the proposals submitted in response to the 2015 ETI RFP. Upon consideration and evaluation of all RFP proposals, Entergy Texas, Inc. has elected to proceed with the self-build alternative, which is generally described in the RFP. The self-build alternative will be conditioned on receipt of required internal and regulatory approvals. Each Bidder has been notified whether its proposal(s) have been selected or eliminated from the RFP.”

In that June 2015 RFP, Entergy Services said the Self-Build Option is a combined-cycle gas turbine (CCGT) facility that would be built at ETI’s Lewis Creek site in Willis, Texas. The Self-Build Option will attempt to optimize the maximum capacity of the proposed self-build resource by including in the base plant design heat recovery steam generator (HRSG) duct-firing and options for either chilling or evaporative cooling to the combustion turbine inlet.

The Self-Build Option will not have dual-fuel capability and will be sized at no less than 800 MW (summer conditions, at full load, including duct firing) and no more than 1,000 MW (summer conditions, at full load, including duct-firing). The Self-Build Option is expected to utilize existing infrastructure and resources at the Lewis Creek site, including existing natural gas infrastructure (for gas transportation and related services) and, when feasible, existing administrative or plant support infrastructure (e.g., office facilities, control rooms, fire suppression systems).

The Self-Build Option will be designed to interconnect to two natural gas pipelines. Generation from the resource is expected to interconnect with the MISO system at a 138 kV and/or a 230 kV transmission switchyard located at or near the Lewis Creek site.

If selected in this RFP, the self-build facility is expected to be placed into commercial service by no later than June 1, 2021.

The existing Lewis Creek power plant is a two-unit, 503-MW facility fired by gas and oil.
