Natural Gas Prices Have Changed

The Ontario Energy Board ("OEB") has approved changes to Enbridge Gas Distribution's charges October 1, 2017. On average, these changes will amount to a decrease of approximately 12% annually. The decrease is due to lower natural gas prices in North America. The effect on your bill will depend on how much natural gas your organization uses.

Your current bill has been calculated using the new approved rates for gas consumed from October 1, 2017. The rate chart is included in this notice.

Our supply prices are based on a forecast of market prices for the next 12 months. The forecasted prices are reviewed every three months and adjusted accordingly. If our forecasts are over or under our actual costs, the difference is refunded or collected from customers through cost adjustments.

Gas Supply Charge

The Gas Supply Charge has decreased from 12.0295 cents per cubic metre ("¢/m³") to 9.7911 ¢/m³.

The Gas Supply component of the Cost Adjustment is currently a charge of 0.2262 ¢/m³. This charge, combined with the Gas Supply Charge, results in a new total effective Gas Supply rate of 10.0173 ¢/m³.

Enbridge Gas Distribution does not make a profit on the price of natural gas.

Delivery to You

The "Delivery to You" charge has decreased due to lower delivery related costs.

As of January 1, 2017, Delivery to You includes applicable charges from the Ontario Government's cap and trade program, related to greenhouse gas emissions from the natural gas you use and that we use to deliver it to you, effective January 1, 2017. If you are a customer who is a Non-Large Final Emitter you will be charged a cap and trade Customer Related Charge of 3.3181 ¢/m³ and the cap and trade Facility Related Charge of 0.0337 ¢/m³. If you are a Large Final Emitter you will only be charged the Facility Related Charge of 0.0337 ¢/m³. The effect on your bill will depend on how much natural gas your organization uses.

Load Balancing Charge

The Load Balancing charge has decreased due to lower seasonal load balancing-related costs.

Transportation to Enbridge

The "Transportation to Enbridge" charge has decreased due to lower costs for transporting natural gas to Ontario.

Cost Adjustment

The total Cost Adjustment charge is 0.1032 ¢/m³, effective until September 30, 2018.

Site Restoration Clearance

The Site Restoration Clearance refund is 0.1185 ¢/m³, effective until December 31, 2017. It reflects changes in an estimate of ongoing and future site restoration costs. Site restoration costs are incurred when gas distribution pipelines are replaced or retired over the life of the gas distribution system. 

Rate Adjustment

The OEB has also previously approved a Rate Adjustment. It is a charge of 0.1104 ¢/m³ to reflect the difference between the amount you paid for volumes consumed from January 1, 2016 to December 31, 2016 and the actual costs incurred. The total amount of the charge will be split over two months and appear on your October and November bills in two equal installments.
