Entergy Louisiana pursues CCGT project at Nelson plant site

Entergy Louisiana (ELL) intends to pursue its own self-build, gas-fired power project as a result of a just-concluded request for proposals (RFP) process that took into consideration third-party bids.

Said a brief April 29 notice on the Entergy Corp. (NYSE: ETR) website: “Please be advised that Entergy Services, Inc. (ESI), acting under the oversight of the Independent Monitor, has concluded its evaluation of the proposals submitted in response to the 2015 ELL/EGSL RFP. After considering ESI’s evaluation of all RFP proposals, Entergy Louisiana, LLC has elected to proceed with the self-build alternative, which is generally described in the RFP, and a proposal for a power purchase agreement (PPA). Both the self-build alternative and, assuming negotiation of the definitive terms, the PPA will be conditioned on receipt of required internal and regulatory approvals. Each Bidder has been notified whether its proposal(s) have been selected or not selected from the RFP.”

EGSL is Entergy Gulf States Louisiana. No details are given on the possible PPA and whether the size of it would impact the size of the self-build plant.

The September 2015 RFP says the Self-Build Option is a combined-cycle gas turbine (CCGT) facility that would be built at EGSL’s Nelson site in Westlake, Louisiana. 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 650 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 Nelson site, including existing natural gas infrastructure (for gas transportation and related services). 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, 230 kV, and/or a 500 kV transmission switchyard located at or near the Nelson site. If selected in this RFP, the self-build facility is expected to be placed into commercial service by no later than June 1, 2020.

Notable is that Entergy Louisiana is currently before the Louisiana Public Service Commission for approval of its St. Charles Power Station (SCPS), a 980-MW (nominal) combined-cycle gas turbine (CCGT) facility to be built in St. Charles Parish, Louisiana. That was a self-build option out of a 2014 RFP.
