2008 electricity distribution rate applications

Jump to:

As part of its regulation of the electricity distributors, the Ontario Energy Board established a multi-year electricity distribution rate setting plan, which indicated that, commencing with the 2008 rates, each year a limited number of distributors would be identified and if any of them sought a general change in their distribution rates, the application had to be based on Chapter 2 of the Board’s Filing Requirements, issued November 14, 2006 (EB-2006-0170). This meant that the distributor had to submit a forward test year, cost of service based application (CoS application).

For any of the other distributors seeking approval to change their distribution rates, the basis for their applications would be a mechanistic, formulaic update of their current rates (IRM application), similar to the process used for the 2007 rates.

On May 4, 2007, the Board identified a list of 25 electricity distributors that would be subject to this process, should any of them seek changes to their distribution rates for 2008. The letter requested that each of these distributors file a letter with the Board confirming they will file a forward test year rate application by August 15, 2007 for rates to become effective May 1, 2008. The filing instructions and timing for the remaining distributors will be issued later this year.

The following table lists the key standard documents of a distributor’s rate application. These documents include:

  • The “Application” as filed by the distributor, provided as an Adobe Acrobat PDF file.
  • The “Notice of Application” issued by the Board and to be published by the distributor. The purpose of the Notice is to inform the affected ratepayers and other stakeholders of the application, its nature and the impact on affected customers. It also outlines the process for the making of submissions and/or participation in the Board’s proceeding to consider the application.
  • For those distributors applying for rates based on the IRM application, the “Decision Model” provides the application model modified as necessary to reflect the Board’s decision.
  • The “Decision and Rate Order” issued by the Board when it has adjudicated on the application (the Decision) and the subsequent Rate Order that reflects the Decision in the actual Tariff of Rates and Charges.

Today the Board announced the price escalator (or inflation index) for the 2nd Generation Incentive Regulation mechanism for adjusting electricity distribution rates effective May 1, 2008.


Consistent with the Board’s findings in its December 20, 2006 Report of the Board on Cost of Capital and 2nd Generation Incentive Regulation for Ontario's Electricity Distributors, the Board will use the annual percent change in the Implicit Price Index for National Gross Domestic Product (GDP-IPI) for Final Domestic Demand.  On March 3, 2008, Statistics Canada published change for 2007 over 2006.  The percent change is 2.1% (ref: http://www.statcan.ca/english/freepub/13-010-XIE/2007004/tables/table07.htm).


The Board will adjust the price escalator in each distributor’s Incentive Regulation model such that this change is reflected in the 2008 distribution rates for electricity distributors that are under the 2nd Generation Incentive Regulation mechanism.
