Transmission Principles

A. Transmission planning must be linked to the financing of transmission enhancements. Regional Transmission Organizations (RTO) can provide the needed link between planning and financing.

B. Because of the lead time needed to build new transmission capacity, it is necessary to begin transmission planning before RTOs are in place. Such transmission planning should mesh with the transmission planning RTOs will be conducting when they are established. Once RTOs are operational, the information used for transmission planning processes should be supplemented by information derived from market-based congestion management systems.

C. The process for identifying and studying transmission enhancements needs to involve all affected parties, including states and provinces, and be conducted on a regional basis. The appropriate size of the regional depends on the proposed transmission enhancement and could be as large as the Western Interconnection.

D. The western transmission system needs to enable competitive markets that foster the achievement of the goals of secure, adequate, reliable, diverse, affordable and environmentally-sound power for the West.

E. The evaluation of transmission needs and proposed projects should consider transmission and non-transmission alternatives.

F. As a general principle, the cost of transmission capacity expansion should be borne by the beneficiaries of the new capacity. The cost of transmission expansion to improve the reliability of power delivery in a particular area should be allocated to the consumers in that area. The cost of expansion to allow new generation to reach load should be borne by the generators, unless potential customers for the power can be induced to participate voluntarily. It may be difficult to identify the individual beneficiaries of transmission expansion proposals to mitigate market power. In such cases, spreading the cost of the transmission upgrades among all consumers in the area may be appropriate.

G. The permitting and siting of new transmission facilities needs to be expedited through early identification of information governmental agencies need to make permitting and siting decisions and by coordinating project review and decision-making schedules among regulatory agencies.
