San Diegans will soon be able to enjoy the offset benefits of imported renewable energy, thanks to SDG&E's new transmission line project. Construction has begun on a new 230-kilovolt transmission line that will run from Sycamore Canyon in Poway, all the way to the Peñasquitos Substation in Torrey Hills.

The new transmission line will help improve power distribution reliability and will also integrate more renewable energy into the system in an effort to meet new state-mandated goals.

Of course, the project did not make it to this point without a few hiccups along the way. SDG&E was forced to make alterations to the original design and scope of the project after the Carmel Valley Community Planning Board sent a letter to the California Public Utilities Commission. The letter pointed out certain environmental risks that the project could impose on the community along with impacts that construction would have on local residents and businesses. After all was said and done, SDG&E chose to follow an alternative plan for the project that avoided significant aesthetic impacts to the community and biological resource impacts to the Sycamore Canyon Preserve. The alternative project design would underground a double circuit 69-kV power line under Carmel Mountain Road and East Ocean Air Drive and reroute new towers leaving the existing wooden H Frame structures in place but de-energized. The alternative plan triggered a 7 month delay on project completion while increasing overall costs significantly.

Performance Utility Supply is proud to be a part of this ongoing project which broke ground on January 4, 2017. During the construction process, PUS is assisting SDG&E underground a portion of the overhead power lines along the transmission path. We are also providing logistics and transportation services for equipment and necessary construction materials. The materials provided included a complete sub-structure package for the transmission lines, custom fittings. sweeps, and risers.

We're privileged to be working with SDG&E and Source Power on this project that will eventually help alleviate the problems energy demand could impose on San Diego County.
