In a District Energy system, a central plant produces hot water, steam or chilled water and delivers it to a group of buildings or facilities via an underground piping network. District Energy can integrate Renewable Energy and Combined Heat and Power.
District Energy is simple, safe, reliable, environmentally-responsible and not capital intensive for the users.
Global Leadership in District Energy
It is during the post Second World War massive reconstruction period that Dalkia started to install and manage its first district heating and cooling network - some 60 years ago. Today with 890 urban district energy systems, Dalkia is the largest operator worldwide with 2010 revenues of $3.7 billion or 33% of total annual revenues.
Everyday, Dalkia provides its customers with unequalled, reliable and efficient end-to-end solutions combining heating and cooling systems, electricity generation when feasible and associated management services.
Dalkia offers complete one-stop solutions for various energy schemes for homogenous or mixed user development. Dalkia designs, finances, builds, owns, operates and maintains the district energy scheme infrastructure, or any combination.
