Wahah Electric Supply Company of Saudi Arabia Ltd. (WESCOSA) was formed in 1976 to meet the growing needs of energy and power sector in the Kingdom of Saudi Arabia.

WESCOSA has experienced substantial growth since its formation. The company now offers a wide-range of products designed and manufactured to meet the highest quality standards of the power generation and distribution industry.

At the beginning, WESCOSA’s product line includes only the assembly of switchboards, panel boards and accessories under a license agreement with Westinghouse Electric Corporation, USA. The demand of electrical equipment in Saudi Arabia has fast risen in the succeeding years, causing WESCOSA to diversify its product lines and started manufacturing NEMA VE-1 Electrical Cable Ladders, Cable Tray, and Cable Trunking & Supports.

The company has grown tremendously at an early stage of its operation. In 1979, WESCOSA started assembling oil filled transformers under a license agreement with Westinghouse Electric Corporation. Assembly of dry type transformer was added to WESCOSA products in 1983, again under a license agreement with Westinghouse. In 1988, Westinghouse sold its transformer division to WESCOSA. Since, then WESCOSA has continued manufacturing oil filled distribution transformers of the highest quality standards independently, now holding its own type-test certifications.

It was in 1988 when a major turn of event took place in WESCOSA when Ali Zaid Al-Quraishi & Bros. Co. purchased the Westinghouse share
