PJM Electricity Interconnection Organization’s capacity locked in at price of $136 per MW

PJM’s capacity auction secured a record amount of new generation, demand response and energy efficiency resources for the 2015/2016 delivery year to keep the grid reliable as dozens of coal plants retire and are converted to natural gas.

The auction, known as the Reliability Pricing Model (RPM) auction, procured 164,561 megawatts (MW) of capacity resources at a base price of $136 per MW, compared to the price last year of $125.00 per MW.

Capacity prices were higher than last year’s because of the retirement of existing coal-fired generation, due to environmental regulations, which go into effect in 2015.

PJM serves 60 million people in 13 states in the Mid-Atlantic and Midwest and the District of Columbia. Capacity prices were higher in northern Ohio and the Mid-Atlantic region.

For the Mid-Atlantic, PJM said capacity will cost $167 per megawatt.

The Mid-Atlantic region includes utilities served by Pepco Holdings Inc’s Atlantic City Electric, Delmarva Power and Pepco; Exelon Corp’s Baltimore Gas and Electric and PECO; FirstEnergy’s Jersey Central Power and Light, Metropolitan Edison and Pennsylvania Electric; PPL Corp’s PPL Electric Utilities, Public Service Enterprise Group Inc’s Public Service Electric and Gas; and Consolidated Edison Inc’s Rockland Electric.

In FirstEnergy Corp’s northern Ohio territory, PJM said the capacity price will be $357 per megawatt due to the high number of power plant outages in that area.   With the exception of the AEP territory, Capacity is a fairly small component of the retail price of electricity, and the cost of capacity at the retail level tends to be averaged out over several years.
