NextEra’s 10.4-MW Green Mountain battery project in Pa. ready for testing

Pennsylvania Windfarms LLC on Dec. 16 requested that the Federal Energy Regulatory Commission accept for filing a Common Facilities Agreement that will allow its affiliate, Green Mountain Storage LLC, to access and use certain interconnection facilities owned by Windfarm to enable a 10.4-MW battery storage facility.

This battery project will participate in markets operated by PJM Interconnection. Windfarm anticipates that Green Mountain will synchronize its battery facility with the transmission grid on or after Dec. 17, 2015, for the purpose of testing its facility and receiving back feed energy. Accordingly, Windfarm requested waiver of the commission’s 60-day prior notice filing requirement to allow the agreement to become effective on Dec. 17, one day after the filing.

Windfarm previously owned and operated a wind energy generation facility located in Somerset County, Pennsylvania, that was decommissioned on Dec. 1, 2015. Windfarm interconnected its wind facility with the transmission system owned by Somerset Rural Electric Cooperative Inc. (SREC) in order to participate in markets operated by PJM.

Storage’s battery facility will operate separately from Windfarm’s decommissioned wind facility. However, the Common Facilities owned by Windfarm are currently necessary for Storage’s battery project to interconnect with SREC’s transmission system and participate in PJM markets. 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 by Windfarm.
