  FDS Co-Generation  


The FDS Project includes plans for a 135 MW Co-Generation Facility powered by steam produced by the waste heat from the Coke Plant's nonrecovery coking process. The co-gen facility will produce approximately 1,000,000 MW-hrs of electricity annually, which is enough electricity to power 100,000 average homes, with NO ADDITIONAL POLLUTANTS being emitted.

Co-Gen Process

Hot waste gas from the FDS Coke Plant must be cooled so that it can be treated in a flue gas desulfurization (FGD) unit to remove sulfur dioxide. The most efficient way to accomplish this cooling is to use heat recovery steam generators, which convert the waste heat into steam. This steam is then used for the production of electricity with no additional air pollutant emissions.

Facility Design

The co-gen facility will occupy approximately 5 acres of land located directly adjacent to the FDS Coke Plant. The facility will include a triple uncontrolled extraction non-reheat condensing steam turbine generator unit fueled by superheated steam. Electric power generated by the facility will be delivered to the electric utility grid with a portion of the electricity utilized for on-site services and by the FDS Coke Plant. The co-gen facility features include a single steam turbine building, a maintenance and water treatment building, exterior tankage, cooling towers, 138kV substation and general roadway access to the major equipment.

Electrical Grid Interconnection

When operational, electricity generated by the co-gen facility be a network resource interconnected into the American Transmission Systems Incorporated (ATSI) system. Transmission of the electricy into the grid will be overseen by PJM Interconnection. PJM Interconnection is a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.

FDS has completed all grid interconnection study phases and has a Memorandum of Understanding with ATSI on generator interconnection. More information can be found at: and
