Energy-efficient design, retrofits and hydro power: Encana

Encana’s three largest gas processing facilities in B.C. have reduced greenhouse gas emissions by 860,000 tonnes per year.

Encana has electrified the three largest gas processing facilities in B.C. through the use of hydroelectricity. This shift away from electricity generated by natural gas reduces greenhouse gas (GHG) emissions by 860,000 tonnes per year. When planning its Saturn Natural Gas Plant, Encana worked with B.C. Hydro to identify design improvements to make both the compressor site and the gas gathering system much more energy-efficient than a standard design. When approved in 2016, the plant was designed to operate using hydroelectricity instead of natural gas, and included a number of design features to improve energy efficiency. 

Encana’s extensive technology retrofit program is currently underway at sites in northeast B.C. This is a scalable operation where Encana plans to swap out many gas pneumatic controllers and pumps across hundreds of well sites and implement instrument-air control systems at older facilities to reduce methane emissions.
