GI Endurant LLC (DBA GI Energy) specializes in providing consulting, development, underwriting, management, construction and advisory services related to energy generation, distribution and efficiency assets, specifically in the small to medium scale combined heat and power and ground source heat pump industries. Our firm operates under the following strategic business units:

  • Consulting, Development and Management
  • Ground Source Heat Pump (GSHP)
  • Operations, Maintenance and Service

GI Energy assists facility owners, land developers and municipalities in the development of sustainable energy systems. The company helps customers leverage advanced technologies to hedge high/volatile energy prices, improve energy reliability, reduce environmental impacts and increase asset value. This includes designing, developing, financing, owning and operating
energy distribution, generation and efficiency enhancement technologies.

GI Energy provides sustainable energy solutions for buildings. Trusted clients include blue-chip organizations such as Land Securities, Skanska, and Walgreens.

GI Energy has two core technology offerings. Our Ground Source & Air Source Heat Pumps operation in the US business has been at the forefront of the industry here, benefitting from the long track record of our UK parent. While our Combined Heat & Power business has installed a range of high profile power plants across the US. Both technologies allow us to deliver substantial energy savings and CO2 reduction measures for our customers. Increasingly we are exploring ways to combine these high-efficiency solutions into hybrid designs that maximize ROI and minimize cost.

We were founded in 2001 and have grown to become the UK market leader in large scale ground source heat pump solutions. We are also an emerging force in providing large combined heat and power systems driven by our recent acquisition of Endurant Energy, a US based CoGen specialist. Our innovative approach to renewable energy technology and funding solutions, along with our comprehensive service, means we are widely recognised as being best in sector. These strengths have allowed us to form strong relationships with key customers such as Walgreens.
