FERC okays gas pipeline to serve repowered Salem Harbor plant in Massachusetts

On May 14, the Federal Energy Regulatory Commission approved a July 2014 application from Algonquin Gas Transmission LLC for approval to construct and operate approximately 1.2 miles of 16-inch-diameter lateral pipeline and a metering and regulating station in Salem, Massachusetts, to serve the repowered Salem Harbor power plant.

Algonquin plans to construct and operate the Salem Lateral Pipeline to provide 115,000 dekatherms (Dth) per day of firm natural gas transportation service to Footprint Power Salem Harbor Development LP’s redeveloped Salem Harbor Station, which will be a 630-megawatt quick-start combined-cycle, natural gas-fired generation facility. The company will replace shut oil- and coal-fired units at the site.

In addition, Algonquin plans to construct and operate a new metering and regulating station (Meter Station) on Footprint’s property. The proposed Salem Lateral Pipeline will extend from a subsea interconnection with Algonquin’s existing HubLine pipeline in Beverly Harbor, across a peninsula jutting into the harbor, under another body of water (Collins Cove), and make landfall again before ending at the proposed Meter Station. The pipeline will be constructed in approximately 0.58 miles of open waters and the onshore portion of the pipeline will cross two industrial properties, one commercial property and one residential property.

Algonquin estimates the cost of the project to be $62,700,000.

Said the Footprint Power website about the Salem Harbor project: “Footprint is developing a quick-start combined-cycle gas turbine on an 18-acre portion of the 65-acre site. This facility will have the ability to provide 674 MW of power to the grid with nearly half of that output available in 10 minutes and the remainder over the course of an hour. In the near term, as one of the most efficient units on the grid, we anticipate that it will run a lot. Over time, as more renewable assets are added to the grid, we foresee it will be operated as a ‘firming’ resource that is called upon when intermittent resources like wind and solar are unable to keep up with demand. The facility has been designed to be a good neighbor with engineering, architectural and landscape features intended to reduce sound, improve the visual impact and optimize the options for development on the remaining 40+ acres.”
