Exelon to break ground on new generating units at Perryman

Exelon Generation plans to break ground Monday on two new electric power generating units off Chelsea Road in Perryman.

The roughly $120 million project was announced last year.

Construction on the two 60-megawatt units, generating 120 megawatts total and fueled by natural gas, is set to be launched Monday afternoon at the company's Perryman Generating Station, at 900 Chelsea Road near Bush River.

The company has five units in service at the Perryman station with a total capacity of 345 megawatts, four of which are oil-fired combustion turbines and one of which is fueled by natural gas, according to an Exelon news release.

Those units were originally built to provide standby power in times of peak demand and that will be the use for the additional units, according to Bob Judge, regional manager of communications for Exelon Power.

"It's called a peaking unit, available for use all the time but used mainly in times of high demand," Judge said.

The new generating units are expected to be completed by June of 2015, Judge said.

The latest project is expected to create up to 95 construction jobs, he said.

According to Exelon, the new Perryman units will help Maryland meet its long-term energy needs with efficient, clean and affordable energy, and is part a more than $1 billion package of benefits Exelon is providing to the state, as part of the Exelon and Constellation Energy merger agreement from 2012.

Exelon and its subsidiaries, which include Baltimore Gas & Electric Company, collectively are Harford County's largest taxpayer. The company also owns the Conowingo Dam and Hydroelectric Plant, as well as the Peach Bottom Atomic Power Station in nearby Delta, Pa.
