Ground broken on 725-MW, gas-fired power plant in Maryland

Competitive Power Ventures (CPV) and partners Marubeni Corp. and Toyota Tsusho broke ground Dec. 2 on the $775m, 725-MW CPV St. Charles Energy Center in Charles County, Maryland.

Located 25 miles southeast of Washington, DC, the CPV St. Charles Energy Center is a state-of-the-art combined-cycle natural gas-fired facility using two reliable, highly efficient General Electric 7F.05 Gas Turbines and a GE D402 Steam Turbine. The project will be constructed by SNC Lavalin Constructors Inc. and operated by EthosEnergy Power Plant Services LLC.

The project will sell its capacity, energy and ancillary services into the transmission-constrained Southwest Mid-Atlantic Area Council (SWMAAC) zone of the PJM Interconnection market. The benefits of a reliable water supply for efficient wet cooling, as well as the site’s proximity to Potomac Electric Power 230-kV transmission lines and the Dominion Cove Point natural gas pipeline, make this one of the most cost competitive projects in PJM.

“Today’s groundbreaking is a major milestone for the CPV St. Charles Energy Center, Charles County and the people of the great state of Maryland,” said Doug Egan, CPV’s Chief Executive Officer. “We are deeply grateful to our partners Marubeni and Toyota Tsusho, the entire CPV team and the many elected representatives, regulators and local officials who worked so hard to make this project a reality. The positive benefits created by this project for the people of this region, have already begun and will continue for decades to come.”

Headquartered in Silver Spring, Maryland, with offices in Braintree, Mass., Houston, Texas, and San Francisco, California, CPV currently has 5,000 MW of conventional generation projects in various stages of development across North America. The company’s Asset Management division has ramped up to more than 4,700 MWs of natural gas generation and wind power under management. CPV Renewable Energy is currently developing 1,300 MWs of wind power projects across North America.

Marubeni was founded in 1858 and incorporated in 1949 with its principal office located in Tokyo, Japan. It manages businesses across a wide range of industrial sectors throughout the world. Marubeni first established its power industry presence through the EPC business, with more than 98 GW supplied/constructed all over the world in various fuel and technology types. Marubeni expanded its business into the IPP arena in the early 1990s, and now owns 10.9 GW of net generating capacity (35.4 GW gross capacity). Marubeni manages its electricity sector investments in the North American electricity market through Marubeni Power International Inc., based in New York, N.Y.

Toyota Tsusho is a general trading company that develops diversified businesses through 950 consolidated companies in Japan and overseas and with customers around the world.

Notable is that there are two other gas-fired projects being planned that would both be located within a few miles of the CPV project.

  • The Maryland Public Service Commission on Oct. 31 issued a certificate of public convenience and necessity for a 755-MW power project of Keys Energy Center LLCKeys Energy Center proposes to construct a new nominal 755-MW, two on one (2×1) combined-cycle, natural gas-fired plant in Prince George’s County, next door to Charles County. The power plant will interconnect with Potomac Electric Power and PJM Interconnection through a transmission line adjacent to the project.
  • Another gas-fired project to be located near the Keys Energy Center is still awaiting PSC approval. Mattawoman Energy LLC, which wants to build an 859-MW, gas-fired combined-cycle facility in Prince George’s County, on Oct. 24 suggested a new procedural schedule to the PSC for the review of this project. The proposed new case schedule includes a July 22, 2015, final order target date. The Mattawoman project is an 859-MW, two-on-one, combined-cycle facility configured with two Siemens H-class combustion turbines, two heat recovery steam generators with supplemental duct firing, and one steam turbine generator in a multishaft arrangement.
