NC: Welcome, energy storage, to North Carolina’s interconnection standards


The North Carolina Utilities Commission (NCUC) has issued an order adopting new interconnection procedures and agreements, including a key clarification that battery storage can be interconnected through the same procedures as other generating facilities. The NCUC order expands fast-track eligibility to systems up to 2 MW, depending on the project’s proximity to a substation and the line voltage. It also requires Public Staff to convene a working group to revise the state’s interconnection rules, if needed, no later than two years after the date the order was issued.

Investor-owned utilities in North Carolina now must submit two quarterly reports to the NCUC. One report provides a snapshot of their interconnection queue; the other addresses queue performance in moving interconnection requests through the study process to a final interconnection agreement and project construction.
