First Nations and Métis; and iv. market participants (collectively, Stakeholders). The AESO’s PIP has been conducted in accordance with the requirements of Section 6.2.1, NID19 and Appendix A2 of the current Alberta Utilities Commission Rule 007 (AUC Rule 007), effective July 4, 2017. From November 2016 to November 2017, the AESO conducted a PIP to assist in preparing its Riverview Substation Needs Identification Document (NID). The AESO directed the transmission facility owners (TFOs), in this case AltaLink Management Ltd.

  • 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.
