Electricity Distribution

DISTRIBUTION is the final stage in the delivery of electric power. Distribution lines carry electricity from the transmission system to individual consumers.

Electricity System Overview

Generation Transmission Distribution Retail/Customer

• Competitive/market based • Fully regulated • Fully regulated • Partially deregulated • Private investment • Cost-of-Service Model • Supports retail • Competitive Contracts competition • Energy only market design • One rate for Albertans • Regulated rate option for small consumers

How is Distribution Regulated? The Utilities Commission (AUC) approves the distribution rates charged by investor-owned and certain municipally-owned wires to ensure they are fair and reasonable. The distribution tariff on a customer’s bill recovers the cost to the wire owner for things such as the design, maintenance, operation, construction and financing of the electric system that delivers energy to a customer’s home. The AUC introduced a new rate regulation initiative, Performance-Based Regulation (PBR), in 2014. PBR is a tool to make utilities more efficient for Albertans while maintaining electric system reliability and service quality. It is also designed to reduce the number, length, cost and complexity of regulatory hearings. This new regulatory initiative is intended to allow the AUC to focus more of its attention on prices and the quality of service, which are important to customers.
