On 23rd March 2010 Stołeczne Przedsiębiorstwo Energetyki Cieplnej (Warsaw District Heating Company) signed a connection contract with the National Stadium in Warsaw.
Under the agreement SPEC will rebuild the existing heating mains and build a new heating chamber and over 200 meters of connections using the energy-efficient technology of pre-insulation. The network under the roads and the facade of the Stadium will be laid in so called lining pipes, which will facilitate any potential replacement or repair of installation and save a lot of unearthing. The facility will be fed from the modernized mains under Zieleniecka Street.
SPEC is also going to install a heat regulation/measurement system in the district heating substation which has already been built. The company will deliver heat to the substation, where it will raise the temperature of the heat carrier flowing in the Stadium installation, below the pitch as well. According to the schedule prepared with Narodowe Centrum Sportu (National Sport Centre), the work started in July 2010 should be completed by the end of August 2010. The final acceptance is planned for the end of September 2010. The value of the investment amounts to nearly PLN 1 million. The heat will flow to the Stadium this very autumn, so that other construction work in the facility can be continued.
The energy delivered to the Stadium is expected not only to heat the pitch but also to provide central heating and hot water for 4 restaurants, exhibition and conference rooms, VIP clubs, football fan clubs and shops, offices, a fitness club, locker rooms and toilets planned in the facility. Altogether SPEC will provide heat for an additional 1 million of cubic meters (so far the company heats 261 million m³ in Warsaw) for the 55,000 football fans in the Stadium. The National Stadium needs 15 MW of heat – approximately the amount used by the two biggest shopping malls in Warsaw or the newly built housing estate, Saska Kępa.
