Alpaca Energy permits replacement gas engines at Pennsylvania project

The Pennsylvania Department of Environmental Protection said in an Oct. 3 notice in the Pennsylvania Bulletin that it intends to issue to Alpaca Energy LLC an air permit covering the construction of three 9,708 bhp (7.2 MW) 4 stroke, lean burn Rolls Royce Bergen B-35:40-V16AG-2 natural gas-fired engine/generator sets.

Each of these sets would be equipped with both catalytic oxidation and selective catalytic reduction (SCR). This power plant is to be located in Canton Township, Bradford County. The facility will also include one 0.64 MMBtu/hour natural gas-fired natural gas line heater; three storage tanks ranging in size from 2,600 gallons to 6,000 gallons; and one desiccant dehydration system.

In October 2014, the department issued an air permit for this station. In that application, five 6,023 bhp Jenbacher natural gas-fired engine/generator sets were approved. These engines were never constructed. The Rolls Royce Bergen engines proposed in this application will take the place of the originally proposed Jenbacher engines.

The department said its review of the information submitted by Alpaca Energy indicates that the air contamination sources to be constructed will comply with all regulatory requirements, including monitoring, recordkeeping, and reporting requirements, and pertaining to air contamination sources and the emission of air contaminants. Based on this finding, the department proposes to issue a plan approval for the proposed construction.

Alpaca Energy filed on May 18 a notice of self-certification as an exempt wholesale generator at the Federal Energy Regulatory Commission. Alpaca said it is developing and constructing a natural gas-fired facility, with a nameplate capacity of 22 MW and a net output of 21.2 MW, that consists of reciprocating engine-generator sets. It will be interconnected to the transmission system owned by Pennsylvania Electric and operated by PJM Interconnection.
