MISO works out interconnect for gas-fired Entergy Louisiana project

The Midcontinent Independent System Operator on Dec. 28 filed with the Federal Energy Regulatory Commission a Generator Interconnection Agreement with Entergy Louisiana LLC as both the power project developer and intercconnecting transmission owner.

MISO has designated this as Project No. J396 in its interconnection queue.

Said the GIA: “Interconnection Customer shall install a 1152 MVA facility, rated at 980 MW gross and 904 MW net, with all studies performed at or below these outputs. The Generating Facility is composed of two (2) MHPSA, 21 kV gas fired combustion turbine units rated at 365 MVA each and one (1) Toshiba 18 kV steam driven turbine, rated at 550 MVA. Interconnection Service provided under this agreement is 904 MW of conditional ERIS that will become 904 MW of ERIS and/or NRIS, where NRIS cannot exceed 904 MW, upon completion of all Network Upgrades.”

The GIA added: “The Points of Interconnection (POI) shall be the point where the three interconnection lines (STG-1C, CTG-1A and CTG-1B) from the Generating Facility terminate on the 230kV bus at Transmission Owner’s Little Gypsy substation.”

The project’s targeted commercial operation date is May 1, 2019.

Entergy Louisiana on Nov. 17 was approved by the Louisiana Public Service Commission to build a new natural gas-fired, combined-cycle power plant in St. Charles Parish. The Louisiana PSC vote clears the way for Entergy Louisiana to move forward with construction on the 980-MW project in Montz, approximately 30 miles from New Orleans, at the Little Gypsy plant site. Scheduled to be in service by June 2019, the plant will cost approximately $869 million to build, including transmission and other project-related costs.
