About GREEY EPC Inc.

1121821 Ontario Inc. began in 1995 by Steve Greey as GREEY Electrical Products to sell SCADA (Supervisory Control and Data Acquisition) plus related technology products to electric utilities.

GREEY Computers was created at the same time to assemble custom PCs, laptops, servers and high end workstations for utilities. Greey Networks was later added to provide on-site computer and network support to small businesses in the Toronto area.

The corporate name was changed to GREEY EPC Inc. which stood for Electrical Products and Computers.

However, the computer and network portion of the business stopped taking on new customers in May 2008 when the Chesswood office was closed.

In 2005, GREEY EPC signed a one year sales and marketing contracts with two suppliers. GREEY EPC then signed a contract with S&C Electric Canada Ltd. as they launched IntelliRupter® in Canada. This contract formally ended December 31, 2022.

In 2014 Ruth Greey joined GREEY EPC after a very successful 32 year career at Hydro One (formerly Ontario Hydro). Until 2017, Ruth consulted on electric utility regulation assisting electric utilities.

Since March 2025 GREEY EPC has been under contract with CEATI for the role of Technical Advisor DEP (Distribution Equipment and Planning).
