District Heating & Cooling

District energy networks provide one of the most sustainable and cost-effective methods to heat and cool spaces.

Innovative, Sustainable District Energy Solutions

District energy is an innovative energy solution that involves the production of thermal energy at a central facility and distribution to buildings via an underground piping network.

Vicinity owns, operates and maintains the largest district energy portfolio across the U.S., providing highly reliable clean steam, electricity, hot water and chilled water to over 230+ million square feet of building space in cities, including Baltimore, Boston, Kansas City, Oklahoma City, Philadelphia, Trenton and Grand Rapids, to name a few.


We provide centrally produced chilled water for cooling, eliminating the need for customers to purchase, operate and maintain chillers and cooling towers. Our steam can also be used to power steam absorption chillers and steam-driven turbine chillers to provide cooling, helping minimize a building’s peak electricity demand and costs.


We provide centrally produced steam and hot water to meet the space conditioning, humidification and process needs of our customers. Whatever the requirements and capital budget may be, we can design and implement an efficient steam or hot water solution. Our heating services are provided from highly reliable and sustainable plants and distributed through robust underground networks.

Domestic Hot Water

For customers using steam for heating, humidification or air conditioning, we offer a way to maximize the building’s cost-efficiency through condensate recovery. By gathering the water that collects as a steam by-product, water is recaptured and recycled to help heat the domestic water supply, resulting in virtually free hot water for our customers.

Sustainable District Energy to Meet Your Energy Solution Needs

As cities become more condensed and extreme weather events increase, having an uninterrupted and sustainable energy supply has become critically important to human health and economic prosperity. For facilities, communities, and campuses that require and consume high volumes of electricity, heat, and chilled water to operate efficiently, district energy is helping to free up space in buildings, save building owners money, and improve reliability and sustainability.

Our steam distribution networks can interface with any type of HVAC building system to provide low cost and reliable thermal energy and cooling. Our centrally-produced chilled water eliminates the need for customers to purchase, operate and maintain chillers and cooling towers.

Several of our existing locations integrate combined heat and power (CHP). CHP simultaneously produces power and thermal energy in the form of waste heat. Vicinity captures this waste heat to produce green, low carbon steam, which is delivered to our customers. CHP consumes far fewer units of fuel than if the two products are produced separately and can exceed 80% efficiency.
