Dominion has received from the Maryland Public Service Commission a Certificate of Public Convenience and Necessity (CPCN) related to its plan to add export capability at its Cove Point liquefied natural gas facility in Calvert County (United States). The certificate was needed for two 65 MW steam turbine generators that produce electricity; the waste heat from two combustion turbines, which are used to drive compressors to produce LNG, will be recycled to produce steam to drive the steam turbines. The PSC approval came 15 days after the Federal Energy Regulatory Commission (FERC) issued its environmental assessment that found the natural gas export project proposed for Cove Point can be built and operated safely with no significant impact to the environment. Cove Point LNG export project will be built on the site of the existing import terminal. It will have a liquefaction capacity of 5.25 Mt/year and should be commissioned in 2017.
