About DEEP

DEEP is a Saskatchewan privately held corporation with a mission to develop Saskatchewan’s geothermal resources for power generation. DEEP’s vision is to be a producer of secure, stable and sustainable energy.

DEEP is developing a unique geothermal (or earth heat) power facility in southern Saskatchewan.  This project will establish the first geothermal power facility in Canada.

DEEP will harness high-quality geothermal resources with existing drilling and power generation technologies to establish a long-term renewable baseload (24 hours a day, 365 days a year) power supply.   DEEP’s long-term goal is to develop 100s of megawatts (MW) of baseload power facilities from small, scalable and repeatable 5-20 MW power plants, each which could power up to 5,000 households.

Geothermal Power Benefits

  • Baseload – Only renewable energy source that can produce baseload power 24/7.
  • Green – Zero carbon-based fuel consumption and facilities have a small footprint that does not interfere with bird migration.
  • Production of useful byproduct – Geothermal power generation produces a useful byproduct – HEAT – which can be integrated to supply greenhouses, fish farms, and food processing.
  • Ongoing supply – With proper reservoir management, geothermal resources will not run out meaning plants fuelled by this energy source can run indefinitely.
  • Building on innovation – The DEEP project will build on Saskatchewan’s world-class drilling technology and expertise.

DEEP Project Highlights

  • DEEP has secured a Power Purchase Agreement with SaskPower for the province’s first geothermal power facility.
  • A $2 million Prefeasability Study was completed on the project in 2014, funded in partnership by SaskPower and Natural Resources Canada.
  • As of November 2018, drilling has commenced and the well will reach a record 3,500 meters making it the longest well drilled in Saskatchewan.
  • A new strategic partnership formed with EPOCH Energy a geothermal company established to unlock heat energy in Canada in partnership with municipalities, First Nations, resource companies, industry, and good growers.

DEEP’s project is located in Southeastern Saskatchewan, a few miles north of the US border near the city of Estevan.  Analysis of thousands of public well records revealed the presence of a vast, “pancake-like’ Hot Sedimentary Aquifer (HAS) in the Williston Basin.  To reach the hot aquifer, DEEP is using conventional drilling to drill the longest well ever drilled in the province (3,500 metres) and power generating technology, which is well established around the world. This project is unique because DEEP is pairing these established technologies with a deep hot aquifer. DEEP is mining heat to produce sustainable, renewable power.

Another primary challenge for SaskPower is meeting Federal Greenhouse Gas Emission regulations – a difficult challenge as its electricity generation is dominated by coal-fueled (35%) and natural gas-fueled (40%) plants. In November, 2015 SaskPower announced that the province will produce 50% of its power from renewable sources by 2030. This means tripling the percentage of renewable electricity generation capacity in Saskatchewan due to the provinces projected power growth requirements. Today, renewables represent 1100 MW of SaskPower’s 4,400 MW current provincial capacity. By 2030, the province will require a total of 3,500 MW of renewable power generation.
