District Energy St. Paul Inc. is a company based in the United States that specializes in developing renewable energy projects in the biomass and waste sectors. The company was founded in 1983 and has since been dedicated to providing sustainable energy solutions to its customers. District Energy St. Paul operates as a non-profit organization and has been recognized as a leader in the renewable energy industry.

The company's primary focus is on developing district heating and cooling systems that utilize renewable energy sources. District heating and cooling systems are centralized systems that distribute hot or cold water through a network of pipes to buildings in a specific area. These systems are more efficient than traditional heating and cooling systems because they eliminate the need for individual heating and cooling units in each building.

District Energy St. Paul's district heating and cooling systems are powered by renewable energy sources such as biomass and waste. Biomass is organic matter that can be used as fuel, such as wood chips, agricultural waste, and municipal solid waste. Waste, on the other hand, is any material that is no longer useful and is typically disposed of in landfills. District Energy St. Paul's systems use both biomass and waste as fuel sources, which helps to reduce the amount of waste that is sent to landfills and also reduces greenhouse gas emissions.

One of District Energy St. Paul's most significant projects is the St. Paul District Energy Heating and Cooling System. This system provides heating and cooling to over 200 buildings in downtown St. Paul, Minnesota. The system is powered by a combination of biomass and waste, which helps to reduce the city's carbon footprint. The St. Paul District Energy Heating and Cooling System has been in operation since 1983 and has been recognized as one of the most successful district heating and cooling systems in the United States.

In addition to the St. Paul District Energy Heating and Cooling System, District Energy St. Paul has developed several other renewable energy projects in the biomass and waste sectors. The company's projects include the use of wood chips as fuel for heating and cooling systems, the use of agricultural waste as fuel for power generation, and the use of landfill gas as fuel for power generation.
