Geothermal power facility makes progress in Saskatchewan

According to the company, DEEP Earth Energy Production Corp. (DEEP), the project is a four-stage build that aims to produce approximately 140 MW of geothermal power generation in 35-MW increments.

Phase 1 development plans include one ~35 MW gross geothermal power facility. Negotiations are ongoing with SaskPower to increase the 5 MW Power Purchase Agreement, secured in 2017, to align with phase 1 development that averages ~35 MW annually of baseload geothermal power.

Upon completion of phases 1 through 4, approximately 140 MW of geothermal baseload power is planned to be produced in four ~35 MW blocks. 35 MW is roughly equivalent to the power required to supply 35,000 households.

Some recent highlights include:

• Completed successful Feasibility Engineering in September;
• Design Basis Memorandum (DBM) engineering currently underway by Calgary-based SCOVAN Engineering;
• Negotiations on-going for enhanced SaskPower Power Purchase Agreement (PPA);
• Secured 80 acres of land under an 18 month offer to purchase for the surface area requirements for the first planned ~35 MW geothermal facility;
• Resolved critical engineering challenges such as corrosion mitigation and reducing parasitic pumping power;
• Reviewing optimization strategies to build low emission Natural Gas (NG) power generation with Carbon Capture and Storage (CCS) for parasitic power requirements (primarily brine pumping). This aligns with the Federal Government's recent unveiling of a 50% tax credit aimed at spurring investment in carbon capture and storage technologies;
• Engaging SaskPower and SaskEnergy on use of natural gas and CCS technologies to help address parasitic loads and related issues;
• Completed Canada's first large volume 53-day production and injection geothermal pump test;
• Entered a strategic partnership with Prairie Lithium to exchange subsurface mineral permits and establish an Area of Mutual Interest (AMI) to explore future lithium opportunities;
• Actively engaged with stakeholders, including local communities. A meet and greet in Torquay was well received by local officials and residents;
• Drilled and tested the Border-06 stratigraphic step out well to demonstrate lateral geological continuity of the geothermal reservoir properties. Production and injection testing demonstrated excellent productivity.
