Affordable and reliable clean energy is right under your feet
Tap into our underground district energy network to rapidly decarbonize buildings, neighborhoods, campuses, and more.
What is District Energy?
An innovative and sustainable solution, district energy involves the production of thermal energy from a central plant that is transported through underground pipes. District energy is safer, more efficient, and more resilient than conventional onsite energy generation with a lower carbon impact—which is beneficial for businesses, communities, and the future.
In addition to improving energy infrastructures and providing 99.99% reliability, district energy doesn’t require onsite boilers or chillers—freeing up space, eliminating the risk of onsite combustion, and reducing upfront capital and ongoing operations and maintenance costs.
