2018 Deferral Account Clearing Bill Adjustments

Enbridge Gas Inc. recently received approval from the Ontario Energy Board (OEB) to dispose of amounts recorded in certain 2018 deferral and variance accounts (EB-2019-0105). (Note: The 2018 deferral account application excludes any 2018 Cap-and-Trade or Demand Side Management (DSM) related deferrals).

This account clearing will result in a one-time delivery adjustment being applied to the April 2020 bill of all customers who received contract rate delivery services in 2018 and a one-time gas supply transportation adjustment being applied to the bills of customers whom Union Gas (now operating as Enbridge Gas) provided upstream transportation services in 2018. North customers who received bundled storage services in 2018 will also see a one-time adjustment on their April bill.

What are Deferral Accounts?

Deferral accounts are used to capture certain differences between Enbridge Gas’ forecast and actual revenues and costs. The differences are either refunded or collected from customers, upon approval by the OEB, and are allocated to each rate class.

Enbridge Gas separates the annual deferral account balances into three separate filings - non-DSM deferral account balances (discussed here), DSM-related deferral account balances, and carbon-related deferral account balances. Separating the deferrals into three separate applications allows for deferral accounts to be cleared and communicated to our customers in a timely manner.
