Union Gas Receives Ontario Energy Board Approval for Rate Changes Effective July 1, 2017

EnerlineInformation for Union Gas South Customers

Union Gas recently received approval from the Ontario Energy Board (OEB) for a change in its rates effective July 1, 2017. These changes were proposed to the OEB earlier this month as part of the Quarterly Rate Adjustment Mechanism (QRAM) and approved as filed.

July 2017 QRAM
QRAM is the mechanism Union Gas uses to review and adjust our rates for changes in natural gas prices. This is done every three months to reflect ongoing changes in the market price of natural gas and to adjust for the difference between the forecasted price of natural gas and actual price from prior periods.

Consider Operational Impacts of Warm Winter to Balancing

All South direct purchase customers (T-service and Bundled-T) and their agents are reminded that balancing transactions are interruptible.

After a warm winter, storage levels can be higher than usual which can impact a customer's ability to deliver incremental supply to their T-service storage or Bundled-T Banked Gas Account.

Incremental supply is an interruptible transaction and more likely to be scheduled earlier in the injection season.  Union Gas' capability to schedule interruptible transactions is a function of capacity and nominated activity. Interruptions can occur at any time if Union Gas' capacity is less than nominated activity.

It is suggested that T-service customers manage their storage balances such that they are adequate when entering the late summer/early fall time frame. It is also suggested that Bundled-T customers looking to deliver incremental supply to balance contract expires do so sooner rather than later.

Celebrating 75 Years of Dawn Storage

Seventy-five years ago, Union Gas pioneered the use of underground storage for natural gas in Ontario - a critical but largely unheralded innovation that to this day ensures Ontarians have a reliable source of affordable energy to get through cold winters.

It was in 1938 that geologist Dr. Charles S. Evans proposed using depleted natural gas reservoirs in the company';s Dawn gas field for underground storage. On Oct. 28, 1942, natural gas was injected into a depleted reservoir at Dawn, marking the birth of Canada’s first commercially successful underground storage.
