Duke files affected systems deal for 100-MW Southampton Solar project in Va.

Duke Energy Progress LLC filed Dec. 16 with the Federal Energy Regulatory Commission an Affected System Operating Agreement between itself and Southampton Solar LLC.

Duke Energy Progress (DEP) requested that the commission expedite its ruling on this filing and issue an order by Jan. 19, 2017.

In April 2016, DEP was contacted by PJM Interconnection, which informed DEP that a proposed new generator to be interconnected directly to the system of Virginia Electric and Power Co. (VEPCO), which is within the footprint of PJM, might cause adverse impacts on the DEP system. The name of the interconnection customer is Southampton Solar, and its proposed new generator is a 100-MW solar photovoltaic facility to be interconnected to a 115-kV transmission line (the Boykins–Handsome line) owned by VEPCO located in Southampton County, Virginia. The PJM queue number for this new generator is AA2-088.

In May and June 2016, DEP participated in meetings with VEPCO, PJM and Southampton. All parties agreed that DEP should conduct an Affected System study to determine the impacts of the proposed generator interconnection on DEP’s system. While the study was being conducted, DEP and Southampton entered into negotiations to create an Affected System Operating Agreement, setting forth the terms and conditions relating to the impact of the proposed generation facility on DEP’s system and the Network Upgrades to the DEP system needed to accommodate the proposed interconnection of such generation facility.

On Oct. 13, 2016, DEP issued its study report which indicated a need for Network Upgrades on DEP’s transmission system and contained the estimated costs and timeline for construction of such upgrades. On Oct. 14, 2016, Southampton executed the agreement. On Oct. 24, 2016, the agreement was executed on behalf of DEP. DEP said it has not yet commenced procurement, installation or construction under the agreement. The In-service date for the Network Upgrades under the agreement is Dec. 15, 2017.
