The North Carolina Utilities Commission on July 27 accepted a December 2015 filing from the City of Charlotte for a registration statement for a new renewable energy facility located in Pineville in Mecklenburg County, North Carolina.
Applicant stated that its 1.059 MW (ac) and 2,367 MMBtu/hour combined heat and power (CHP) facility will generate electricity through the use of biogas derived from anaerobic digestion of organic solids. The thermal energy produced at the facility is to be used to maintain operating temperature of the digester, and the applicant does not intend to seek issuance of thermal renewable energy credits (RECs) associated with thermal output of the facility. Applicant further stated that the facility will become operational in February 2017 and that the electrical output will be sold to Duke Energy Carolinas LLC.
The facility will be located at Charlotte’s largest wastewater plant, the McAlpine Creek Wastewater Management Facility (WWMF). The McAlpine Creek WWMF is located along Lancaster Highway. Internal to the plant, the CHP facility will be located to the southeast of the North Aeration basins and across the street from the Aeration Blower Facility #2, the hot water producing boiler building, and to the south of the North Digester Complex.
The $3.2 million facility will be composed of: a 1,059-kW GE Jenbacher J320 Engine Gas Powered Generator (containerized); gas scrubbing skid and associated equipment; and water feed loop, fuel gas, and electrical distribution tie-ins. As part of standard anaerobic digestion of organic solids, McAlpine Creek WWMF generates a constant supply of methane rich gas.
