On Nov. 28, the Federal Energy Regulatory Commission accepted for filing an interconnection service agreement (ISA) between PJM Interconnection LLC and Invenergy Nelson LLC related to a planned 600-MW, gas-fired power project in Illinois.
PJM on Oct. 9 had submitted for filing the executed ISA among PJM, Invenergy Nelson LLC and Commonwealth Edison. PJM requested an effective date of Sept. 6, 2012, for the Nelson ISA, designated as Original Service Agreement No. 3395. “PJM is submitting the Nelson ISA for filing because it contains non-standard terms and conditions,” PJM noted.
The Nelson ISA facilitates the interconnection to the PJM system of a 600-MW facility located in Lee County, Ill. The Nelson ISA indicates that Nelson will have capacity interconnection rights of 300 MW for Unit 1 and 300 MW for Unit 2.
The ISA says that on or before June 1, 2014, Invenergy must demonstrate commercial operation of two 1×1 combined cycle generating units. Demonstrating commercial operation includes achieving initial operation and making commercial sales or use of energy, as well as, if applicable, obtaining capacity qualification in accordance with the requirements of the reliability assurance agreement among load serving entities in the PJM region.
Invenergy LLC‘s website shows that the Nelson plant is in Lee County, Ill., is under construction and is due for commercial operation in 2014.
A 2008 Illinois Environmental Protection Agency permitting summary for this project noted that a prior developer, LSP-Nelson Energy, went bankrupt during construction of this plant, and that Invenergy Nelson wants to finish installing two of four previously-permitted turbines.
Said an August PJM interconnection report about the project: “Invenergy Nelson, LLC has acquired the nearly completed Nelson Energy Plant after the original owners shuttered the project in 2002. The Invenergy owned 345kV switchyard TSS 942 and 345kV transmission Line 94201 were built to the ComEd line disconnect at TSS 155 Nelson as part of the original project. However, the Nelson Energy facilities were never commissioned into commercial operation. TSS 942 Nelson Energy Center consists of a 345kV straight bus tied via a line disconnect to line 94201 with two (2) generator positions developed with two (2) 345kV breakers and two (2) 345kV breakers installed for future generators. At ComEd’s TSS 155 Nelson, the ring bus was expanded with a 345kV breaker, associated disconnect, a 345kV line disconnect, and live tank CTs to accommodate the new interconnect position for the IC owned 345kV Line 94201. The breakers and bus position were commissioned and placed in service with the 345kV line disconnect to TSS 942 remaining open. The line relaying and revenue metering for 345kV Line 94201 is present at ComEd’s TSS 155 Nelson, but unproven for service.”
