The electricity utility scorecards measure how well Ontario's electricity utilities are performing each year. It is designed to encourage utilities to operate effectively, continually seek ways to improve productivity and focus on improvements that their customers value. Utilities report their scorecard performance results annually, and make the results available to the public. 

The scorecard can be used as a tool for consumers to assess for themselves the value of the service received from their electricity utility. For example: 

  • When service appointments are booked with my utility, how often did they show up on time?
  • How often did my power go out, and how long did the utility take to fix the problem and restore power? 
  • How successful is my utility at issuing accurate bills? 
  • Did my utility answer phone calls from customers in a timely way?

Efficiency rating
0 (2017)

The utility must manage its costs successfully in order to help assure its customers they are receiving value for the cost of the service they receive. Utilities' total costs are evaluated to produce a single efficiency ranking. This is divided into five groups based on how big the difference is between each utility's actual and predicted costs. Distributors whose actual costs are lower than their predicted costs are considered more efficient.

  • 1 = Actual costs are 25% or more below predicted costs
  • 2 = Actual costs are 10% to 25% below predicted costs
  • 3 = Actual costs are within +/- 10% of predicted costs
  • 4 = Actual costs are 10% to 25% above predicted costs
  • 5 = Actual costs are 25% or more above predicted costs

Cost per customer
$0 (2017)

A simple measure that can be used as a comparison with other utilities is the utility's total cost per customer. 

Total cost is a sum of all the costs incurred by the utility to provide service to its customers. The amount is then divided by the utility's total number of customers. This amount does not represent how much customers pay for their utility services.
