Leslie Rd Substation Construction is Underway

Construction of the Leslie Rd Substation is in full swing. Potelco, Inc., the City’s construction contractor for this project, is busy building the City’s ninth substation and the first one to be constructed in the past 12 years.

Richland Energy Services (RES) and Benton PUD are collaborating on the substation, which has been part of RES’ Capital Improvement Plan since 2014 and is necessary to serve the growing load in the southeast Richland area and to provide backup reliability to neighboring RES and Benton PUD substations. In April 2016 the City Council authorized purchasing the land at the intersection of Reata and Leslie Roads in southeast Richland for the new substation. Site excavation has been underway since December 2017, the next big project milestone is the installation of the 62.5 ton 25MVA power transformer on the concrete pad in April. We expect substation construction to wrap up in August 2018.

There are other key activities after that. The Bonneville Power Administration (BPA) will construct its transmission line that will interconnect the Leslie Rd Substation to the BPA transmission system, and Benton PUD is planning to install its transformer in late 2018. We will energize the substation to begin serving RES and Benton PUD customers in March 2019.

The partnership between RES and Benton PUD benefits customers and saves money. By collaborating on the project, we are able to build the infrastructure needed at a substantial savings to customers compared to siting and building two separate substations.
