Services - Clean Energy

Enerpro Engineering specializes in several clean energy solutions, such as:


The electricity generated can be sold or used locally to power on-site facilities, particularly in remote locations where dependable power is essential. More information on these technologies is below.


Stranded Gas

Enerpro is the leading Canadian engineering company in the field of geothermal power generation, having completed multiple projects in the field. These include several front-end engineering and design (FEED) projects, such as:

  • 1 MW FEED project in Fort Liard, NWT

  • 10 MW FEED project in Estevan, Saskatchewan

  • 15 MW FEED cost analysis in British Columbia

  • 109 business case models, Canada-wide

Geothermal power generation harnesses the energy in high-temperature water that has been heated within the Earth's crust. The heat energy contained in the hot water is then converted to electrical energy, and the cooled water is recycled in a closed loop. The process provides a renewable source of clean, emission-free electrical power for a very long time. Today, the biggest challenge with geothermal is the high up-front cost of drilling compared to the long-term energy payback.

Stranded gas is produced natural gas that cannot be delivered to market, either for economic or logistical reasons. The stranded gas reserve may be too small or too remote to warrant a pipeline. It may also have too many contaminants that require expensive treatments. Regional bottlenecks in gas pipelines can prevent the gas from getting to market. It is estimated that over 40% of the tapped natural gas resources in North America are stranded.


Enerpro is focused on provided effective and innovative solutions for reliable power generation systems exploiting stranded gas.

Waste Heat

Hot process fluids generated by facilities can be used to generate power through the Organic Rankine Cycle (ORC). These high temperature fluids may include process water, oil, or engine exhaust. Waste heat recovery produces zero greenhouse gas emissions.

Waste Pressure

The high pressure natural gas from transmission lines must be reduced prior to distribution to an urban center or large facility. When this is done using a pressure reducing valve, a significant and unrecoverable amount of energy is lost from the system.


A turboexpander uses the energy released during the pressure drop to drive a turbine generator. This produces usable or marketable electricity from an energy source that would otherwise be lost. Turboexpanders can also be used to provide refrigeration that can be incorporated into the heat loop and save on cooling costs elsewhere. Using the waste pressure recovery method, Enerpro has completed the front-end engineering and design (FEED) for two 2.5 MW turboexpander projects.
