NextEra’s 18-MW Meyersdale battery project in Pennsylvania now cranking up

Meyersdale Windpower LLC on Nov. 20 asked that the Federal Energy Regulatory Commission accept for filing a Common Facilities Agreement under which it would allow its affiliate, Meyersdale Storage LLC, to access and use certain interconnection facilities to enable an 18-MW battery energy storage facility to participate in markets operated by PJM Interconnection.

Meyersdale Storage synchronized its battery facility with the transmission grid on Nov. 20 for the purpose of testing it and receiving back feed energy. Accordingly, Meyersdale Windpower asked for a waiver of the commission’s 60-day prior notice filing requirement to allow the agreement to become effective as of Nov. 20.

Meyersdale Windpower owns and operates a wind farm located in Summit Township, Pennsylvania, with a nameplate capacity of 30 MW. It interconnects its wind facility with the transmission system owned by Pennsylvania Electric and operated by PJM. Meyersdale Windpower is an exempt wholesale generator that has been granted market-based rate authority by the commission.

Meyersdale Storage is developing an 18-MW battery storage facility also located in Summit Township. Like Meyersdale Windpower, Meyersdale Storage is an exempt wholesale generator that has been granted market-based rate authority by the commission. Its battery facility will operate separately from Meyersdale Windpower’s wind facility and, therefore, Meyersdale Storage has installed its own step-up transformer and revenue meter for the battery project.

However, the Common Facilities owned and operated by Meyersdale Windpower are necessary for the battery project to interconnect with the PJM-controlled transmission system. The agreement does not provide for any transfer of ownership or control over the Common Facilities. At all times, the Common Facilities will be owned, operated and maintained by Meyersdale Windpower.
