WG C5-15 (Costs of Electric Service, Cost Allocation Methods, and Residential Rate Trends)

Reliable and environmentally responsible electricity delivery has received much attention among system operators, including those participating in working groups of CIGRE Study Committee C5. Affordability of electric service is another dimension of electric service provision that also merits adequate attention. The proposed study is to focus on factors impacting affordability of electric service for end-use customers who ultimately pay for the costs incurred through wholesale procurement, operations, maintenance, and planning activities (including power system generation, transmission, substation, and distribution). The study aims to provide an international view of the cost components of electric service (beyond and including energy), the methods of allocating costs applied in practice, and the trends in domestic customers rates over time, by service territory, in both regulated and competitive market environments.
