On April 15, 2019, Duke-American Transmission Co. launched its open solicitation process to allocate remaining transmission capacity on the San Luis Transmission Project, a new 85-mile, 230,000-volt transmission line connecting WAPA’s substation in Tracy to the San Luis, O’Neill and Dos Amigos substations in the Los Banos area. Expressions of Interest from parties interested in acquiring transmission rights on SLTP will be accepted until May 15, 2019 at 5 p.m. EST. Read the news release.

The SLTP project is a unique public-private partnership between DATC SLTP and three public entities – WAPA, the United States Bureau of Reclamation, and the San Luis & Delta-Mendota Water Authority – for the construction of needed transmission facilities and the provision of transmission service to customers at more competitive rates than could be provided without DATC SLTP’s involvement. Providing opportunities for Reclamation to achieve transmission cost certainty over the long term is a significant objective of SLTP, but this project also presents compelling opportunities for transmission interconnection and service that developers may use to unlock the renewable potential in the Valley. DATC’s involvement in financing the SLTP and remarketing the capacity created by this expansion provides value to existing and new customers alike. The efficient distribution of capacity to a broad customer base allows for contracting at costs that would be unachievable for a single customer. WAPA will construct, own, and operate the transmission facilities, providing service over the new line under the terms of the WAPA OATT. In return for its investment, DATC SLTP will enter into a thirty-year transmission service agreement with WAPA, through which it will obtain transmission rights to the entire capacity of the SLTP. Under a FERC approved Rate Schedule, and utilizing the capacity release provisions of the WAPA OATT, DATC SLTP will release up to 600MW of bidirectional transmission capacity. DATC will utilize an Open Solicitation process to accept non-binding Expressions of Interest for SLTP capacity. Upon conclusion of the Open Solicitation period, DATC will commence negotiations with selected parties. DATC SLTP will negotiate commercial terms with willing buyers, release the respective capacity rights, and buyers will become direct customers of WAPA, effectively stepping into the shoes of DATC SLTP as the transmission customer.
