Electric Power Systems Partners with California Department of Water Resources to Modernize the State’s Electrical Infrastructure

May 23, 2023

Voltyx’s operating company, Electric Power Systems (EPS), has embarked on a new project alongside the State of California to assist with its Strategic Reliability Reserve (SRR) program. The California Department of Water Resources (CDWR) and their sister agencies, the California Energy Commission (CEC) and California Air Resources Board (CARB), have been tasked to expand power generation and energy storage facilities in response to extreme events, such as heatwaves and wildfires that have plagued the state over the last several years.

As part of the statewide initiative, the SSR requires upgrades and expansions of existing substation equipment, controls, and protection. In addition, installing emergency power generator units at existing facilities will be implemented to feed directly into the electrical grid during peak-demand events.

EPS has been selected, along with the Engineering, Procurement, and Construction (EPC) contractor, to provide installation and testing of the new and existing electrical apparatus. Included in the overall scope of work, EPS will assist with the following:

  • Demo existing and install new RTU cabinet, including wiring, testing, and commissioning.
  • Demo existing and install new protection and control cabinet, including wiring, testing, commissioning, end-to-end testing, and utility witness testing.
  • Perform acceptance testing of all new medium voltage switchgear.
  • Perform testing of all new and existing apparatus in the 69kV substation. Includes air switches, SF6 circuit breakers, substation transformers, instrument transformers, bus structures, lightning arrestors, DC systems, cables, and grounding.

Since the commencement of the program, each project site throughout the state of California has endured its own unique set of challenges due to the landscape and weather-related setbacks. However, by taking a safety-first approach with planning and execution, EPS has faced these challenges head-on with experienced crews who possess the necessary skill set to deliver high-quality results while minimizing risk.

This ongoing project with the State of California to modernize the electrical infrastructure is critical to both current and future energy needs. EPS is proud to be an integral partner in this effort to provide the reliable and up-to-date infrastructure that will benefit our communities for decades.
