The Palais de Tokyo plant
Launched in 2007, the Palais de Tokyo production plant with a capacity of 52MW, serves the needs of western Paris and offers Climespace a new base station for chilled water production.
The environment prevails
Climespace installed its new station in the basements of the Palais de Tokyo, near the Trocadero in Paris’ city center. The site’s location offers many advantages. The proximity of the Seine allows it to dispense with cooling towers. The site's location was ideal for Climespace’s solution -which was backed by the city of Paris and its Prefecture de Police- and should help avoid the construction of close to 100 stand alone plants and as many cooling towers.
The quality of air and architectural aesthetics of this unique neighborhood is thus preserved. And, as usual, Climespace designed the state-of-the-art plant with its strategic location in mind and a focus on minimizing any potential negative impact an installation of this kind might have on its environment.
Thanks to a mezzanine-type installation, the station only takes up 2200 m2 of the basements of the Palais de Tokyo. The curator of this famous museum dedicated to contemporary art still has access to most of the museums basements as storage space. Museums tours have not been affected in any way.
This unit includes eight water chillers generating 54 MW of capacity at 0,7°C.
The site's main assets
- Absence of sound pollution thanks to special insulation
- Absence of visual pollution through the use of the Seine’s water supply
- No additional traffic generated by the site
- No architectural modifications required to the Palais de Tokyo
The Canada plant
Commissioned in May 2002, the Canada plant production unit, totaling 52 MW, is unique in that it is invisible. Built on five levels 30 meters underground, it is located near the banks of the Seine and cannot be seen or heard while in operation.
The eight water chillers are cooled by water from the Seine. A pumping station channels the water towards five exchangers by means of a primary cooling circuit.
Water from the secondary circuit then feeds each cooling unit.
The eight water chillers are arranged in four rows, each holding two units connected in series, on two floors. The water temperature is lowered from 10°C to 6°C by the first group and then from 6°C to 2°C by the second before being delivered to the end network.
By operating without a cooling tower, the plant saves over 500,000 m2, of drinking water per year, as well as the costs of water treatment that would be required, and eliminates any resulting plume of steam and the spread of bacteria associated with it. As soon as it was launched, the plant was able to serve a number of leading sites such as the George V and Plaza-Athénée hotels and the Guimet Museum, among others.
The Halles plant
Historically, the Halles plant is the first chilled water production facility in Paris’ district cooling system. Built in 1978, it was initially intended to supply the cooling and backup power for the Forum des Halles. Today the plant is connected to Climespace’s central network and contributes to supplying the chilled water needed to meet its customers’ needs.
Work on the project was launched in 2004 and completed in 2008.
The Halles plant now has 42MW of capacity delivered by 10 water chillers.
The Halles plants also enjoys a cold energy storage equipment.
In addition, the plant is the only one of its kind to produce electricity for three separate networks: the Forum des Halles, the Halles’ underground walkways and the Louvre Museum. This energy is supplied by 5 generators.
The Auber plant
Commissioned and built in the RER train station in 2009.
The 23MW plant is a powerful source of energy capable of addressing the growing needs of the local business community. It now serves over 20 new customers whose only alternative would be to build their own stand-alone cooling units, possibly including cooling towers.
The cooling station’s location in the heart of the RER station, made this building site project a particularly challenging venture:
The Opera plant
Commissioned in 1994, the Opera plant is located in the basement of the Galeries Lafayette, one of Paris’ foremost department stores.
The plant is connected to Climespace’s central network and also serves the department store.
The plant, which is dedicated to the production of chilled water has 33 MW in power capacity. It includes 9 water chillers and an ice storage unit. The Opera plant has a cooling system that uses cooling towers.
Work to enhance the plant is planned between 2010 and 2012.
The Etoile Station
The Etoile plant, located in the basements of the BNP bank on avenue Kléber in Paris’ 16th arrondissement, has been operational since 1999. Originally a stand-alone unit, it was subsequently converted and is now connected to the central network.
It currently generates 8 MW. In 2006, it was entirely refurbished and includes 4 water chillers.
The plant is is cooled by cooling towers equipped with an anti-steam device in order to avoid plumes.
The Bercy plant
The Bercy plant, assembled in 1993 in the facilities of CPCU boiler room near the Gare de Lyon in the 12th arrondissement, feeds Paris’ eastern network, also known as the Bercy network.
The plant was built to supply Paris' Left Bank area (urban development zone located in Paris' 13th arrondissement, near the Bibliothèque Nationale de France).
Its six water chillers provide 44 MW in power capacity.
The Bercy plant, like the Canada and Tokyo plants, is cooled by water from the Seine.
