Panda Mattawoman Power Project

The Panda Mattawoman Power Project is a clean natural gas-fueled, 990-megawatt combined-cycle generating station. Once built, the plant is expected to supply the power needs of up to 990,000 homes and should infuse approximately $1.2 billion into the Maryland economy.

Mattawoman Power Plant Facility Highlights

The Mattawoman Generating Station will:

  • Contribute approximately $1.2 billion to the area’s economy during construction and the plant’s first ten years of operation
  • Create approximately 700-800 construction jobs; 25 direct jobs to operate the plant and 32 indirect jobs to support the plant
  • Utilize the latest, most advanced emissions-control technology, making it one of the cleanest natural gas-fueled power plants in the United States
  • Use Siemens H-class gas turbines — the world’s first generation technology to achieve operating efficiencies of 60 percent.
  • Not use potable water for cooling purposes, conserving Maryland’s natural supply of drinking water
  • Use treated wastewater for cooling purposes and return no wastewater to a treatment facility — subsequently preventing the discharge of harmful nutrients into the Chesapeake Bay
  • Be located in an existing I-2 heavy industrial zone, in a Developing Tier (not a rural tier), in order to preserve home values
  • Have one of the lowest profiles of any power plant in the United States and be setback 565 yards from the nearest road to reduce sightlines

Market Need

  • More than 20 gigawatts of coal-fired power plant retirements have been announced to take place in the PJM (Pennsylvania, New Jersey and Maryland) market in the next few years, setting the stage for tightening reserve requirements
  • More than 70 gigawatts of power plants in PJM average 56 years of age
  • Total peak demand growth of over 1.4 percent per year, or approximately 2,200 MW per year
  • Maryland currently imports approximately 40% of its power needs from out of state, causing severe transmission constraint issues

About St. George's County, MD

Prince George's County borders Washington D.C. and is just 37 miles south of the city of Baltimore. The county was formed from land in Calvert and Charles Counties by an act of the General Assembly on St. George's Day, April 23, 1696. The county is named for Prince George of Denmark, husband of Princess Anne, heir to the throne of England.

According to the Prince George’s County Historical Society, Prince George’s County:

  • Has more than 325 designated Historic Sites, 73 individual National Register properties, and eleven National Register Historic Districts.
  • Was home to John Carroll, the first Catholic bishop in the United States, and to Thomas John Claggett, the fifth Episcopal bishop (but the first consecrated on American soil) in the United States.
  • Has the oldest continuously operating airport in the world (College Park).
  • Has one of the first experimental planned communities in the country (Greenbelt).
  • Was the cradle of thoroughbred racing and produced two Triple Crown winners (Gallant Fox and Omaha from Belair Stables in Bowie).
  • Is known as the most affluent and successful majority-black county in the United States.
  • Grew from a rural tobacco-producing county of 30,000 in l900 to an advanced technology population of over 800,000 today.

Local Support

"Panda has done an especially good job of listening to the people of Prince George's and Charles' Counties and incorporating what they've learned into the design of their plant."
-- M.H. Jim Estepp, president and CEO, Greater Prince George's Business Roundtable

"We're very excited about this project. The power plant will have a significant impact on our region's economy for years to come. It will expand the tax base, enlarge payrolls and drive revenues for contractors, suppliers, engineering firms, hotels, restaurants, retailers and a host of other businesses. The plant will create an estimated 700-800 union construction jobs, 25 direct jobs to run the facility and 32 indirect jobs to support it. This is great for Southern Maryland."
-- Gwen S. McCall, president and CEO, Prince George's County Economic Development Corporation
