What Wholesale Electricity Supply does
Wholesale Electric Supply Company of Houston, Inc. (WES) is a family-owned independent electrical products distributor headquartered in Houston, Texas, founded in 1949 and operating under McKellop family ownership since 2012. The company distributes cables, enclosures, switchgear, transformers, breakers, panel boards, lighting, and related electrical supplies to the petrochemical, commercial construction, industrial manufacturing, marine, drilling, OEM, utility, and government sectors, with a particular concentration along the U.S. Gulf Coast. Its core proprietary asset is CMMS (Construction Material Management System), an internet-based platform created in 1979 that links engineering, purchasing, construction, accounting, and vendors to manage procurement, warehousing, delivery, and reporting for capital projects worldwide, with deployments on more than 350 projects to date. Supporting offerings include a Cable Management System (1986), a Job Control System (JCS), the in-house Hoffman Certified Modification Center, and OSI, a cloud-based on-site inventory ERP. CMMS was first commercialized in 1979 on an Eastman Kodak project in Kingsport, Tennessee, and the firm was the first North American electrical distributor to achieve ISO certification (1992).
WES operates 12 domestic branches across Texas and Louisiana plus 5 international offices in Canada (Kitimat, BC), Australia (Karratha, WA), Singapore, the Philippines, and Thailand, with a global Export Services department supporting projects in Latin America, the Middle East, Europe, Africa, and Asia. The company is the largest Eaton stocking distributor along the Gulf Coast and the largest Okonite distributor in the United States, and it has held the ExxonMobil MRO Blanket since 2002. Customer logos include ExxonMobil, Bechtel, KBR, Fluor, Cheniere LNG, Angola LNG, Motiva, Marathon Petroleum, Hitachi Energy, the U.S. Army Corps of Engineers, the Department of Defense, and the Department of State.
Revenue is generated through four primary streams: product distribution at markup from manufacturer partners (Eaton, Okonite, ABB, nVent Hoffman, Southwire, Encore Wire, Service Wire, General Cable); professional services including project management, modification shop fabrication, and switchgear coordination; managed services including CMMS material management, integrated supply, vendor-managed inventory, and OSI cloud-based on-site supply; and transaction-based counter sales and e-commerce through shop.wes-hou.com. Go-to-market is sales-led with enterprise field sales, a dedicated strategic accounts team serving as a single point of contact for multi-site MRO customers, counter sales at each branch, and an online storefront. Pricing is quote-based with 30-day net payment terms. WES holds ISO 9001:2015 certification (since 1992), WBENC women-owned certification since 1999 (recertified through 2026), ISNetworld and DISA compliance credentials, and was the recipient of the 1994 Green Light Ally Award, the 2019 Bechtel Supply Chain Award, the 2022 Hitachi Energy Industrial Distributor of the Year, and the 2022 Marathon Petroleum Diverse Supplier of the Year.
