Is Terrapin a geothermal company or a waste heat company?

​

Terrapin specializes in converting Heat to Value. Though geothermal energy comes from underground, and waste heat is found in industrial operations, the process of converting these resources into a profitable form is the same. Depending on the temperature of the resource, the heat can be converted to emission-free power through an Organic Rankine Cycle (ORC) system or used directly as heat for internal processes or district heating networks.

Terrapin projects can produce emission-free heat and power, environmental attributes, and ESG stories for the energy industry. Because Terrapin’s business is in unlocking the inherent value of heat, Terrapin refers to itself as a Heat to Value company.

What is Alberta No. 1?

​

Alberta No. 1 is the province’s first conventional geothermal heat and power facility and Terrapin’s signature energy project. Located in the Municipal District of Greenview, Alberta No. 1 is proudly being built in Alberta by Albertans.

The project will consist of a wellfield, a binary cycle electrical generation plant, and district heat use infrastructure. Estimated to be completed in Q2 of 2025, Alberta No. 1 will produce 83,220 MWh of clean, constant power and 985 terajoules of clean, constant heat per year.

Alberta No. 1 is partially funded by Natural Resources Canada as part of their Emerging Renewable Power Program.

What makes Terrapin projects so innovative?

​

Terrapin’s turnkey project development model takes projects from origination through to completion at no cost to the client. Leveraging Terrapin’s network of engineering, construction, and financing partners, Terrapin clients receive a customized energy solution that reduces their carbon intensity in an economic way. This is opposed to the traditional method of energy or efficiency investments, which requires the client to scope, manage, and pay for the project themselves.

Terrapin transforms waste heat recovery into an innovative clean energy play for independent power producers. Waste heat recovery is traditionally deployed in the energy industry as an internal efficiency measure. When waste heat recovery is strategically implemented by the right team of developers, technology providers, and financiers, waste heat can become a significant source of independent revenue for developers and clients.
