NextEra unit seeks EWG status for 18-MW energy storage project in Pa.

Meyersdale Storage LLC, which is developing an energy storage project in Pennsylvania, on Sept. 2 filed with the Federal Energy Regulatory Commission a notice of self-certification as an exempt wholesale generator.

Meyersdale Storage is a wholly-owned direct subsidiary of ESI Energy LLC, which is part of NextEra Energy Resources LLC, which is a unit of NextEra Energy (NYSE: NEE).

Meyersdale Storage will own and operate an 18 MW energy storage system located in Somerset County, Pennsylvania. The facility will operate within the PJM Interconnection market, and interconnect with Pennsylvania Electric‘s 115-kV Davis substation.

The commission has recognized that an energy storage system such as this qualifies as an “eligible facility” and that its owner can qualify as an EWG, the notice said.

Meyersdale Storage also filed a Sept. 2 application with FERC for market-based rate authority, saying: “Meyersdale Storage, a Delaware limited liability company, will own and operate an 18 megawatt (‘MW’) energy storage system located in Somerset County, Pennsylvania. The Facility will interconnect with Pennsylvania Electric Company’s 115 kV Davis substation and is currently scheduled to be energized on or after November 5, 2015, in order to begin the sale of test power. The Facility’s commercial operation is expected to begin in December, 2015. The entire output of the Facility will be sold into PJM’s market. A notice of self-certification as an exempt wholesale generator is being submitted concurrently with this Application.”

PJM on July 30 fiied with FERC an executed Interconnection Service Agreement with the Meyersdale Windpower LLC unit of NextEra covering a new battery storage project at an existing wind farm in Pennsylvania that is interconnected into the Pennsylvania Electric-owned system. The Meyersdale ISA supersedes an ISA among PJM, Meyersdale Windpower and Pennsylvania Electric that was filed in 2004 for the wind project alone.

“The Meyersdale ISA facilitates the interconnection to the PJM transmission system of a battery energy storage facility to an existing wind farm project,” said the PJM filing. “The Meyersdale Wind Farm and Battery Energy Storage System (‘Customer Facility’), is a generating facility located in Summit Township, Pennsylvania. The Customer Facility has a Maximum Facility Output of 48 MW. The Meyersdale ISA further indicates that Meyersdale shall have Capacity Interconnection Rights in the amount of 5.1 MW.” 

This project is located in Somerset County, Pa. The ISA says the equipment configuration is: twenty 1.5-MW NEG Micron/Vestas wind turbines, and nine 2-MW Parker inverters, batteries and associated controls and equipment. Under the interconnection agreement, on or before Dec. 31, 2015, Meyersdale must demonstrate commercial operation of the nine battery storage systems.
