In Middlesex County, New Jersey, it wasn't enough for National Energy Resource Corporation (NERC) to convert landfill gas (LFG) to energy at just a single landfill—the company incorporated three large landfills to produce enough LFG to power the county's wastewater treatment (WWTP) operations and to supply green power to the grid.

NERC connected LFG production facilities at the Middlesex County, Edison Township, and Industrial Land Reclaiming Landfills with an 8-mile pipeline that runs beneath the Raritan River. It connects to the largest LFG-fueled advance-stage energy center east of the Mississippi River.

The project's highlights include the following:

  • Dual 5.5 combined-cycle combustion turbines, dual heat recovery steam generators with auxiliary duct firing, and a 10.6 MW steam turbine.
  • Gross design rating of 20 MW, with additional capability.
  • Ample cost-competitive thermal energy for WWTP operations.
  • Excess power sold as green power throughout New Jersey.
  • LMOP Project of the Year, 2001.

NERC applied groundbreaking finance and development structures over five years to overcome implementation barriers. Now, the project generates nearly $2 million annually in monetized Section 29 tax credit revenues.
