About Us

Our Purpose Statement:

  • The purpose of Independent Electric Supply is to be an integral part of our customers and manufacturing partners’ growth and success.
  • We will do this by providing  exceptional customer service, well trained friendly associates, industry leading added value and most important, by being recognized as the lowest total cost supplier in the markets we serve

Independent Electric Supply opened in 1976 with ten employees to serve electrical contractors working in the high-tech aerospace industry. Today, IES operates 12 electrical supply branches in Northern California and 7 branches in Arizona. All of our branches maintain local inventory which is supported by our two Central Distribution Centers. Our 200,000 square foot CDC in San Leandro, CA  and our 135,000 square foot CDC in Phoenix, AZ replenishes the branch inventories daily as well as performing customer deliveries to your required destinations.

Our focus is to serve the electrical construction market with dedicated associates specializing in lighting, switchgear, wire management, tool & safety, renewable energy, and enhanced logistics solutions to meet and exceed our customer’s specific needs.

In addition, we operate two specialty divisions—Independent Power Systems (IPS) with offices in Sacramento, Westminster, and San Diego, and Independent Utility Supply (IUS) with full line brancheslocatedin West Sacramento and Tracy.

IPS supplies switchgear, transformers, substations and related products to the commercial and industrial markets, offering complete design/build services and expert project management.

IUS provides the utility contractor with complete material packages for both electrical and gas projects, specializing in underground distribution line extensions and upgrades as well as street lighting projects.

With over 40 years of experience and employing more than 500 associates, IES has proven to be the leading source for electrical material in the markets we serve.

In August 2011, Independent Electric Supply was acquired by Sonepar USA, a division of the privately held Sonepar Group.

Sonepar is recognized as the world’s largest electrical distributor, maintaining a worldwide presence in 41 countries on 5 continents and employing nearly 40,000 associates.
