The system will serve the La Marina, the Marcabarna wholesale market, the international exhibition center (Fira) in Gran Vía de L'Hospitalet and the City Metropolitana. It will be the first district heating and cooling network to provide centralized air conditioning for domestic use. Cumulative forecast revenue comes to around €600 million. Over the lifetime of the project, the energy plants will produce more than 2.9 million MWh of power, 56% of this amount from renewable or recycled energy sources.
This ambitious project, chosen by the Barcelona City Hall, will significantly reduce CO2 emissions and will emit very few suspended particles. The improved energy efficiency and use of thermal solar systems will meet customers' needs and provide them with high-quality service. The Barcelona City Hall, Enagás, the Institute for Diversification and Saving of Energy (IDAE) and the Catalan Energy Institute (ICAEN) are all partners in the operation.
The project is based on recovering and recycling cold energy from the Enagás regasification plant and on energy recovery from the thermal treatment of vegetation residue from the parks and gardens of Barcelona. With this proposed solution, Dalkia will reduce primary energy consumption of fossil fuels by 67,000 MWh per year, equivalent to the consumption of a city of 60,000 people, and cut CO2 emissions by 13,400 metric tons per year.
