Invenergy is in construction on 584-MW plant in Illinois

Invenergy LLC is in construction, with commercial operation expected in 2015, on the 584-MW Nelson gas-fired power plant in Illinois.

In 2004, Invenergy completed the acquisition of the partially constructed Nelson Power Generating Facility in Illinois. The Nelson facility, originally projected as a four-unit, 1,160-MW power project designed around General Electric 7FA gas turbine technology, will be completed as a 584-MW combined cycle facility configured as two 1×1 combined cycle units. Construction is underway with commercial operation scheduled for 2015.

James Shield, the Executive Vice President and Chief Development Officer for Invenergy, mentioned the Nelson project by way of background in testimony filed Sept. 27 at the Minnesota Public Utilities Commission. The testimony was in support of Invenergy’s offer to expand one gas-fired power plant and build a new gas-fired plant in Minnesota to meet a future resource need of Northern States Power d/b/a Xcel Energy (NYSE: XEL).

Invenergy has developed over 7,500 MW of utility-scale renewable and natural gas-fueled power generation facilities in the United States, Canada, and Europe, Shield noted. This includes more than 5,700 MW of projects in operation, with more than 1,800 MW under contract or in construction.

Invenergy has a large portfolio of natural gas-fueled generating facilities in the U.S. and Canada. This portfolio includes green field projects initiated by Invenergy, as well as facilities acquired and completed by it. Operating projects in North America total 2,245 MW and include:

  • Cannon Falls Energy Center (Minnesota, 357 MW);
  • Spindle Hill Energy Center (Colorado, 314 MW);
  • Hardee Power Station (Florida, 370 MW);
  • Grays Harbor Energy Center (Washington, 620 MW); and
  • St. Clair Energy Center (Ontario, Canada, 584 MW).

In addition to these operating projects, Invenergy is developing new natural gas-fueled electric generating facilities across North America.

In November 2012, the Federal Energy Regulatory Commission accepted for filing an interconnection service agreement (ISA) between PJM Interconnection and Invenergy Nelson LLC related to the Nelson project. The Nelson ISA indicates that Nelson will have capacity interconnection rights of 300 MW for Unit 1 and 300 MW for Unit 2.

Said an August 2012 PJM 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.”
