PJM Interconnection on April 28 filed with the Federal Energy Regulatory Commission an executed interconnection service agreement with Doswell LP and Virginia Electric and Power d/b/a Dominion Virginia Power for the existing Doswell power plant.
“The Doswell ISA facilitates the interconnection to the PJM transmission system of an increase of 726 MW (Maximum Facility Output) at the Doswell Facility, comprised of Doswell Complex 5 and Doswell Complex 6 (combined units) located in Ashland, Virginia,” said the filing. “The Doswell ISA indicates that Doswell shall have capacity interconnection rights (‘CIRs’) in the amount of 606 MW of CIRs which consist of 303 MW for the Doswell Complex 5 unit and 303 MW for the Doswell Complex 6 unit.”
The Doswell Complex 5 maximum facility output is 363 MW, as is the maximum output for Doswell Complex 6.
The Doswell Facility as covered by the ISA consists of four Siemens v84.2 combustion turbine generator sets in a two-2×1 configuration with two Alstom steam turbines, and associated balance of plant auxiliary equipment. The two combined cycle units are referred to as Doswell Complex 5 and Doswell Complex 6.
Section 4.0 of the Doswell ISA indicates that the Doswell ISA will become effective on May 6, 2017. This date is necessary to ensure that the effective date of the Doswell ISA coordinates with the termination of a pre-existing power purchase agreement with an unnamed customer.

The LS Power website shows Doswell as a 776-MW, gas-fired simple-cycle/combined-cycle facility. In an August 2013 integrated resource plan, Dominion Virginia Power said it has a 605-MW power contract with Doswell that expires in May 2017.
Doswell, in a January 2013 filing at the Virginia Corporation Commission, said that it owns a natural gas-fired facility with a total capacity of about 760 MW (summer rating), consisting of a 605-MW combined-cycle facility and a 155-MW simple-cycle combustion turbine facility. The facility is located in Hanover County, Va., and is interconnected with Dominion Virginia Power’s transmission system, which is under the operational control of PJM. The electrical output of Doswell’s combined-cycle facility is committed to Virginia Power under the power purchase agreement that expires in May 2017. The Doswell facility’s combustion turbine makes merchant sales.
Doswell has said it has tried and failed to sell its power plant to Dominion Virginia Power, or to work out an extended power sales agreement. The utility has instead chosen to build its own new gas-fired capacity.
