The DEEP’s project is located in Southeastern Saskatchewan, a few miles north of the United States border, near the city of Estevan. Analysis of thousands of public well records in southern Saskatchewan revealed the presence of a vast, “pancake-like” Hot Sedimentary Aquifer (HSA) at >3000 metres depth at the base of the Williston Basin. This aquifer has a lateral continuity over 100s of kilometres, is 100-150 metres thick and has a measured temperature of >120. The Williston Basin HSA alone may support 200 MW capacity or more from about 20 such plants of 5-10 MW each, courtesy of the vast resource.
DEEP and SaskPower have signed Power Purchase Agreement (PPA) as per an announcement made on May 16, 2017. Read more
DEEP’s long term strategy is to build up to 200 MW of geothermal power facilities. SaskPower’s demand for renewable power is growing – Saskatchewan has seen a 16% increase in demand over the past five years.
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.
