A survey of transmission tariffs in North America

One goal of electricity restructuring is to facilitate voluntary transactions in workably competitive wholesale electricity markets. Unfettered wholesale trading, however, can only take place under open and comparable access to transmission by all market participants at non-discriminatory tariffs. Since a rich body of literature exists for topics like nodal pricing, transmission rights, ancillary services, and optimal dispatch, this paper's focus is to survey the transmission tariffs actually used in North America to achieve open and comparable transmission access. In doing so, it provides a practical guide to developing a transmission tariff. illustrated by the survey's role in shaping the tariff filed by a company like the British Columbia Transmission Company (BCTC) with its regulator, the British Columbia Utilities Commission (BCUC).
