North Carolina accepts renewable energy status of U.S. EcoGen project in Florida

The North Carolina Utilities Commission on Oct. 13 accepted the April 12 registration for renewable energy credit (REC) purposes from U.S. EcoGen Polk LLC for a facility to be located in Fort Meade, Florida.

Applicant stated that its 74.9-MW (ac) biomass-fueled facility will become operational on Jan. 1, 2019, and that the facility will use wood-waste and plantation grown wood as a source of fuel and fire small amounts of natural gas for boiler start-up and stability control. The developer said it will participate in the North Carolina Renewable Energy Tracking System (NC-RETS) to facilitate the issuance of RECs.

Said the Oct. 13 approval: “Based upon the foregoing and the entire record in this proceeding, including the source of fuels stated in the registration statement, the Chairman finds good cause to accept registration of Applicant’s biomass-fueled facility as a new renewable energy facility. … Pursuant to Commission Rule R8-67(d)(2), because Applicant is using multiple fuels to generate electricity, the facility shall earn RECs based only upon the energy derived from the renewable energy resources in proportion to the relative energy content of the fuels used. Applicant shall annually file the information required by Commission Rule R8-66 on or before April 1 of each year.”

The facility, with 66 MW net of capacity, is to burn biomass fuel in a subcritical bubbling fluidized bed (BFB) boiler to produce steam that will be expanded through a condensing non-reheat steam turbine generator (STG) with three feedwater heaters for the production of electricity. The steam will be condensed to feedwater, heated and pumped back to the BFB boiler to complete the cycle.

Emissions from the BFB boiler are to be controlled both within the BFB boiler and by a separate air quality control system (AQCS) located downstream of the BFB boiler. The facility also includes a wood fuel handling system with receiving, stacking, storing, reclaiming and boiler feed conveying systems as well as an AQCS to meet air permit stack emissions requirements that includes a selective non-catalytic reduction (SNCR) system, a dry sorbent injection system (DSI), a selective catalytic reduction (SCR) system, and pulse-jet type fabric filter. 

The project is to be located on a 52-acre site in the City of Fort Meade in Polk County, Florida. The facility will be owned by U.S. EcoGen Polk LLC, a wholly-owned, direct subsidiary of U.S. EcoGen LLC. The BFB boiler is to be supplied by the Andritz Group.

The application said the facility is projected to be placed into service on Jan. 1, 2019.

Attached to the application filed in North Carolina was an October 2011 approval from the Florida Public Service Commission of a power purchase agreement for this project with Progress Energy Florida (now known as Duke Energy Florida).
