The AESO is an independent, not-for-profit entity responsible for the safe, reliable and economic planning and operation of Alberta’s electric system. The High River and Okotoks Transmission Project is one of the projects identified in the FATD. This project will: • ensure the transmission system will meet growing demand in developing areas and maintain a reliable supply of electricity • ensure power from new generation plants, including gas and wind power, is connected to Alberta’s electric grid Did you know? A reliable transmission system keeps costs low by connecting diverse sources of power generation to the grid. Transmission costs make up about 10% of the average residential utility bill. Generation costs – the cost of actually creating power – make up the largest portion of a bill, at more than 50%. The transmission system always hooks up the lowest priced generator to the grid first, so generators compete to provide Albertans with cost-effective electricity. Next steps 1 We will use the input we receive from stakeholders during consultation and the results from further studies and field work to determine the best routing options for this project. 2 After the consultation process is complete, we will use the input gathered to determine the preferred and alternate routes for this project and file a Facilities Application with the Alberta Utilities Commission (AUC). 3 The AUC will review the Facilities Application through a process in which stakeholders can participate. The AUC can approve, approve with conditions or deny a Facilities Application.

  • Electricity Distribution
    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 Alberta 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. To view the AUC’s brochure on PBR, visit www.auc.ab.ca/items-of-interest/Performance-BasedRegulation/Pages/default.aspx Electricity Distribution Owners & Operators Distribution lines are owned and operated by a mixture of investor owned utilities, municipalities and Rural Electrification Associations. • The four major distribution companies in Alberta are EPCOR, ENMAX, ATCO and FortisAlberta.
