Power generator PSEG Power LLC, a unit of Public Service Enterprise Group, has taken an equity stake in PennEast Pipeline Co. LLC's proposed $1 billion, 100-mile pipeline from Pennsylvania to New Jersey, PennEast said Thursday. The pipeline would run from Luzerne County in northeastern Pennsylvania to Transco's Trenton-Woodbury interconnection in New Jersey (see Shale Daily,Sept. 5;Aug. 12). The pipeline, which is projected to enter service in 2017, would transport up to 1 Bcf/d and is targeting Marcellus Shale gas supplies. Additional pipeline partners include AGL Resources; NJR Pipeline Co., a subsidiary of New Jersey Resources; South Jersey Industries; and UGI Energy Services (UGIES), a subsidiary of UGI Corp. PSEG Power, which would be a shipper on the pipeline, will have a 12% interest in PennEast. The other PennEast Pipeline Co. members each will have 22% interest. Preliminary engineering studies have begun, and a formal application is to be filed with the Federal Energy Regulatory Commission next year. UGIES is the project manager and would operate the pipeline.
