The petition requested authorization to allow Northern to return to customers credits for the Daily Delivery Variance Charges (DDVC) collected during the 2025-2026 winter season using the interim settlement rates, with the balance of the DDVC charges refunded to customers upon Commission approval of the pending settlement. On June 26, 2026, the Commission denied that request and issued an order granting a limited waiver to delay distribution of DDVC credits until a final order on the pending settlement is issued. Consistent with the Commission's order, DDVC refund credits will be issued to customers following the Commission's final action on the settlement.
