Complaints

0.04 (2022)

We measure this per 1000 customers so utilities that serve much larger or smaller populations can be compared against each other.

Efficiency rating

5 (2022)

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

$1,312 (2022)

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.
