Dalkia is a leading operator of district heating and cooling networks internationally. We manage 800 district and local heating or cooling systems worldwide, particularly in France, the United Kingdom, Italy, Germany, Central and Eastern Europe and the Baltic States. In general, we do not own the systems, but usually provide management, upkeep and maintenance services on behalf of the local authorities that do. The systems are designed to supply heat, domestic hot water and air conditioning to public and private buildings such as schools, healthcare establishments, office buildings and residential buildings.

Extremely comfortable solutions

Simple and safe, the heating and cooling systems enhance the comfort of residents. The fact that there is no need to store materials or flammable products eliminates risks, and the compact systems can be installed anywhere. Durability and ease of use are among the undisputed qualities of Dalkia's heating and cooling systems.

A Choice of energy solutions

Upgraded systems equipped with cogeneration units are suited to a wide range of energy sources:

• Coal and heating oil, which can be stocked to ensure secure fuel supply.
• Natural gas, which is piped and therefore more flexible.
• Alternative sources like geothermal energy, biomass and waste-to-heat, which are cost efficient and environment friendly.

Challenges

• Guarantee a reliable, comfortable supply of heat at the lowest cost.
• Improve system reliability and building and occupant safety.
• Increase energy efficiency as part of an energy conservation policy.
• Upgrade sites and adapt them to actual demand.
• Integrate systems into the urban landscape.
• Reduce atmospheric emissions.

The primary benefits are:

• Reduced initial capital cost investment in heating and cooling equipment for the customer
• Reduced energy costs through the use of higher-efficiency products
• Reliable thermal energy products - heating and cooling
• Reclaiming valuable space in facilities by avoiding the need for separate boilers or chillers and using our central plant
• Avoiding labor expenses related to the maintenance of boiler or chillers
• Focusing on core businesses while a service provider focuses on energy needs
• Preserving the environment - energy by-products are converted into useful thermal energy, resulting in less waste and fewer air emissions and
• Replacing aging infrastructure.
