Transmission Planning

We accept requests from electric utilities, firm-power customers, private power developers, and independent power generators to interconnect with our transmission system. Interconnection is a separate but parallel process to the transmission service request process detailed in Western's Open Access Transmission Service Tariff (63 FR 521).

We evaluate each request for interconnection separately and we’re subject to meeting reasonable needs of the requesting entity. Western assumes responsibilities to operate and maintain its interconnected facilities.
