Frequently Asked Questions: Operating Imbalances

You do not have to trade Operating Imbalances. You may choose to trade any volume up to the tradable amount shown on your Operating Imbalance statement. Any untraded Operating Imbalance will be added to your Operating Imbalance Carryover Account.
The OFO Settlement established the Operating Imbalance Carryover Account to help smooth out the repayment of Operating Imbalances and to minimize their impact on system imbalances. Each month, each Core Procurement Group's untraded Operating Imbalances are moved to its Operating Imbalance Carryover Account. Also each month, one-twelfth (1/12) of this account balance is considered the first transaction for that CPG. Billing and supply adjustments will now be made to the carryover account. In this way, the impact of untraded Operating Imbalances and adjustments are spread out over 12 months. If this account has a balance of between -5000 and 5000 Dth, the CPG may elect to have the entire balance considered the first transaction rather than just 1/12.
