Thermoelectric Generator's (TEG) history began with NASA's Apollo program in 1975. 3M developed the technology for the TEGs to generate the Apollo mission's power on the moon. In 1975, GPT's founders, a group of entrepreneurs from the oil and gas industry, purchased the thermoelectric technology from 3M and chose Bassano, Alberta as the site for their manufacturing plant. The company name at that time was Global Thermoelectric. In 2015 the company name was changed to Gentherm Global Power Technologies (GPT).

After adapting the thermoelectric technology for the oil and gas and telecom markets in Alberta, GPT's business rapidly grew. Thermoelectric generators quickly became the world standard for Industrial remote power systems. From the first few installations in Canada, GPT's Thermoelectric Generators (TEGs) are regularly used in the following industries:

• Gas pipelines
• Wellheads
• Offshore platforms
• Telecommunications
• Security surveillance and monitoring

To date there have been more than 35,000 Gentherm Global Power Technologies’ (GPT) TEGs installed in 55 countries.

But GPT evolved to more than just TEGs:

GPT's success with TEGs led to the development and integration of other industrial remote power products. GPT now provides remote power systems where TEGs are not ideal, including larger loads and liquid fueled systems.

GPT offers solutions based on industrial gensets, hybrids, photovoltaics (Solar power), grid-connected systems and combined heat and power systems. GPT constantly monitors new power technologies, working with industry partners to select and integrate options to meet their unique remote site power needs.
