2010 electricity distribution rate applications

Jump to:

As part of its regulation of electricity distributors, the Ontario Energy Board established a multi-year electricity distribution rate setting plan which indicated that, commencing with 2008 rates, a limited number of distributors would be identified each year to file a future test year cost of service application based on Chapter 2 of the Board’s Filing Requirements, re-issued May 27, 2009. The plan would run for four years enabling each rate regulated distributor in the province to rebase its rates at least once during the four year plan.

For any of the other distributors seeking approval to change their distribution rates, distributors would file a mechanistic, formulaic update to their current rates based on the Board’s incentive regulation mechanism (IRM).

On January 29, 2009, the Board issued a letter identifying a list of 16 electricity distributors that would be subject to the cost of service process in 2010 and 23 in 2011.  The letter requested that any distributor wishing to change their filing year should file a letter with the Board by February 13, 2009. The Board received comments from a number of distributors requesting that they be moved from 2010 to 2011 and vice versa. These comments were posted on the Board’s website. On March 5, 2009 the Board issued the final list of 22 electricity distributors that are to file applications no later than August 28, 2009.

It is anticipated that the following distributors will file cost of service applications for rates effective May 1, 2010:

  • Burlington Hydro Inc.
  • Cambridge and North Dumfries Hydro Inc.
  • Chatham-Kent Hydro Inc.
  • Clinton Power Corporation

The Board has announced the price escalator (or inflation index) for the 2nd and 3rd Generation Incentive Regulation mechanisms for adjusting electricity distribution rates effective May 1, 2010.

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 1, 2010, Statistics Canada published the change for 2009 over 2008 as part of the National Economic Accounts.  The percent change is 1.3% (click for Statistics Canada referenceclick for Statistics Canada reference (2) ).

The Board will adjust the price escalator in each distributor’s Incentive Regulation model such that this change is reflected in the 2010 distribution rates for electricity distributors that are under the 2nd and 3rd Generation Incentive Regulation mechanisms.
