NRG Energy deactivates units at three New Jersey power plants

The latest PJM Interconnection list of deactivated power plant units, updated to May 11, shows that while coal-fired power has seen a lot of deactivations lately, some gas- and oil-fired units are also being shut.

The list shows that on May 1, units at three New Jersey plants were deactivated:

  • Gilbert CT, Units C1-C4, three of the units with a capacity of 25 MW and C1 at 23 MW;
  • Glen Gardner, CT1-CT8, all eight units at 20 MW each; and
  • Werner CT, C1-C4, all four units at 53 MW each.

As usual, PJM doesn’t identify the owners of any given power plant, but ownership can be worked out in each case. The GenerationHub database shows the primary fuel for the Gilbert and Glen Gardner units is natural gas, while oil is the primary fuel with the Werner units.

NRG Energy (NYSE: NRG) plans to retire by May 2015 the four simple cycle combustion turbines at its Werner Generating Station in South Amboy, N.J., said the New Jersey Department of Environmental Protection during permitting last year for the plant. Werner consists of four simple cycle turbines of 53 MW each combusting #2 fuel oil. The facility is owned and operated by NRG REMA LLC.

All the combustion turbines at Werner are High Electric Demand Day (HEDD) units under New Jersey code. “Beginning May 1, 2015, these turbines will be subject to the HEDD emission limits in Table 7 at N.J.A.C. 7:27-19.5(g),” the department noted. “As currently operated, the four turbines are not capable of complying with these emission limits. If additional emission controls, capable of enabling these turbines to comply with the applicable HEDD emission limits, are not installed and operated by May 1, 2015, these turbines must cease operation on this date. NRG has indicated in the latest update to their 2015 Plan (submitted in January 2014, pursuant to N.J.A.C.7:27-19.30) that they intend to retire the four turbines by May 1, 2015.”

NRG said in its Feb. 27 annual Form 10-K report that it has submitted deactivation notices for generation capacity at the following facilities acquired through a merger earlier this decade with GenOn Energy:

  • Gilbert CT Units 1-4, Deactivate May 2015, 98 MW net;
  • Glen Gardner Facility, May 2015, 160 MW net; and
  • Werner Facility, May 2015, 210 MW net.
