Climespace, leader of District Cooling in Paris


Production and storage

The CLIMESPACE chilled water generating plants are made up of refrigeration units that cool the distribution circuit chilled water from 15°C to 5°C. These plants also consist of other equipment such as pumps, electrical equipment...

Climespace's Production schema

Les Halles plant: long-standing installation
Built in 1978, the plant was originally intended to provide cooling energy and back-up electricity to the Forum des Halles. Today this plant is connected to the CLIMESPACE central district cooling system and helps to provide chilled water required to meet customer needs. Between 2004 and 2008, major renovation work was carried out.
Cooling capacity: 42 MW
The Halles plant now has a capacity of 42 MW delivered by 10 refrigeration units and cold energy storage.
In addition, this plant has the special characteristic of generating back-up electricity for two separate power grids: the Forum des Halles and the Louvre Museum. This energy is supplied by five generators.
The Canada plant: Zero emergence
The eight refrigeration units are installed in a cylinder 19 meters in diameter and 29 meters deep and are cooled by water from the Seine. A pumping station is used to circulate water from the Seine through five plate exchangers after filtration. This primary cooling circuit does not receive any injection of chemical products. The water in the secondary cooling circuit then cools the condenser of refrigeration units.
Cooling capacity: 52 MW
The eight refrigeration units with a total cooling capacity of 52 MW are divided into four lines of two groups installed on two levels. The two groups on the same line operate in series: the water temperature is lowered from 10°C to 6°C on the first group and then from 6°C to 2°C on the second group, the temperature delivered to the network.
By not using a cooling tower, this plant avoids the consumption and processing of 500,000 m3 of drinking water per year. It generates no plume of steam and removes any risk of Legionella type bacterial dissemination.
The Tokyo plant: Protected environment
Located in the basement of the Palais de Tokyo, this plant has many advantages. The proximity of the Seine actually allows cooling towers to be dispensed with. This location, favourable to the operation of a plant cooled by water from the Seine, has eliminated the need to construct around a hundred stand-alone installations and as many cooling towers. The environment, both in terms of the air quality and the architectural aesthetics of this exceptional area, has been well preserved.
Cooling capacity: 52 MW
Thanks in particular to a mezzanine-style installation, the plant occupies an area of 2,200 m2 in the basement of the Palais de Tokyo, created by the excavation of the original crawlspace. The museum dedicated to contemporary design has therefore been able to maintain and operate all its noble surface areas. This unit includes eight refrigeration units with a total capacity of 52 MW at 0.7°C.
The main advantages of the site
– Lack of noise thanks to special purpose insulation
– No visual impact on operations thanks to the use of water from the Seine
– No additional traffic generated by site operation
– No architectural modification of the Palais de Tokyo
The Auber plant: an extraordinary site
The Auber plant integrated with the RER A station was commissioned in 2009. This plant, with a capacity of 24 MW, can cope with the growing demand for cooling needs in the central Paris business district.
Infrastructure sharing: This plant’s installation in the heart of a high-traffic station has been possible thanks to the sharing of technical space with the RATP. The situation of the plant made site completion particularly complex: the presence of the underground train network, the routing of materials by rail and at night, etc.
The Opera plant: In the heart of the “Grands Magasins”
Commissioned in 1994, this plant is located in the basement of Galeries Lafayette.
The power of this plant dedicated to chilled water production is 33 MW. It includes 9 refrigeration units and ice storage. The Opera plant has a cooling system using cooling towers.
The Etoile plant: Managing peak demand
Since 1999, the Etoile plant has been installed in the basement of the SCOR building located on Avenue Kleber. The fruit of a conversion of an independent production unit, it is inter-connected with the Centre network, with an installed cooling capacity of 8 MW. In 2006 it was completely renovated and includes 2 cold units. This plant is cooled by air cooling towers equipped with anti-steam plume batteries and produces during peak periods and high temperature conditions.
The Bercy plant: Serving a changing neighbourhood
Installed in 1993 in the 12th arrondissement near the Gare de Lyon, this plant supplies the Eastern network, known as the Bercy network. It was created to supply the Paris Rive Gauche area (Development Zone located in the 13th arrondissement of Paris, around the Bibliothèque Nationale de France). Installed capacity is 44 MW through 7 centrifugal refrigeration units. The Bercy plant, like the Canada and Tokyo plants, is cooled using the water from the Seine.
The PNE-Philharmonie: Cooling and geothermal energy
The Philharmonie de Paris and CLIMESPACE came together in 2011 to study a cold supply solution and installation of a plant in the theatre’s basement. Construction of this new production unit represents a dual opportunity to develop a new network in the area of La Villette and to achieve longer-term coverage with the Paris Nord Est network for connections of up to a total of 12 MW. The Cité de la Musique in this sector is already connected to the CLIMESPACE district cooling system (800 kW).
Climespace's energy storage

Energy storage

CLIMESPACE storage systems facilitate response to one-shot and large demands for cooling capacity.
Since cooling requirements are lower at night than during the day, the refrigeration units continue to operate in order to generate cooling energy for storage in tanks. During the day, this stored cooling is used to cover demand peaks.
The cooling energy can be stored in two forms: chilled water or ice. The latter is more advantageous because it can store more energy in a given volume.

  • Chilled water storage at the Tour Maubourg: located on the top level of a car park, this installation is made up of 13 tanks storing a total of 12,000 m3 of chilled water, a volume equivalent to an energy of 90 MWh. The water is stored at 3°C.
  • Opera: the Opera plant has ice storage with a capacity of 320 m3, equivalent to 20 MWh.
  • Les Halles: the Les Halles plant has ice storage equivalent to 30 MWh.
