Similar experiences in Spain and Europe


The District Heating or even the District Heating & Cooling systems are being supported by the different public authorities, both through the European Community , by regional and in many cases, by municipal authorities, because theses systems represent the most energy efficient solution when compared with any other thermal energy production solution which furthermore provides for the incorporation of large scale renewable energies.

Hereinbelow, we shall set out some of the most relevant examples of this type of project.


Districlima (Barcelona)

Urban distribution network for heat and cold built in 2002 for heating, cooling and domestic hot water use.

Districlima, S.A. operates this network since 2004 in Barcelona, in the areas of the Forum and the technology district 22@. It has a central plant at Forum zone, that takes advantage from steam coming from municipal waste incineration and condenses its machinery using seawater, and a second plant in district 22@.

The network is 14 km length and supplies 80 buildings, covering an area around 760.000 m2.
Heating power connected is 51 MW and cooling is 73 MW.

Cooling power installed is 35.9 MW, having a cumulative capacity of 40 MW and other ice accumulation of 80 MW.


Ecoenergies (Barcelona)

Network operated by Barcelona City Council and the Local Public Consortium Barcelona Energy Agency, manage by Dalkia Group. It was intended for a residential development around 18,000 dwellings and due to the crisis has not prospered. It is located in the Barcelona Zona Franca, near Seat facilities.

The plant is designed to tri-generation, with heating and cooling devices, ice pool with glycol water (-10º C), heat condensing pumps and photovoltaic solar panels.

Nowadays is prepared to supply an area around 1,200,000 m2 powered with 2,9 Mw, although the project foresees to reach 6 MW with tri-generation and 1,3 MW powered by biomass. The concession was made for a period of 30 years.

It has different branches for:

  • Heat
  • Cold positive
  • Cold negative

The biomass used comes from parks and gardens (13,000 Tonnes) and forestry (17,000 Tonnes), being this last source the most used coming from energy crops.


Heating Network of the University of Valladolid-UVA

Network district heating and domestic hot water with origin in the Thermal Plant that UTE Rebi-Cofely builds on Campus Miguel Delibes. From the main plant, comes a main pipe which gets divided into different branches to enable access to potential customers.

The network is approximately 11,30 km long and includes a last generation leak detection system and has the whole circuit monitored and connected to the remote management system.

The total estimated consumption of the whole network is 22,069,734 kWh/year with a total estimated consumption of chip around 7,886 Tons/year.


Heating Network of Soria

1st phase network with a heating and domestic hot water service for approximately 2,500 dwellings located at the city centre and north part of the city and 20 public buildings and a 2nd phase for 5,000 dwellings and 45 public buildings.

The power plant, almost complete, is a building around 800 m2 located in the NE part of the city. The total estimated consumption for the whole network is 28,000,000kWh/year.

Heating network managed by Rebi (ESCO)


Heating Network of Olvega (Soria)

Heating network supplying several public buildings through a district heating network, replacing fossil fuels such as diesel, propane and natural gas for local resource such as biomass.

The network is fed exclusively with biomass and consists of a generation plant fueled by wood chips Pine coming from own production.

Heating network managed by Rebi (ESE).

Móstoles District Heating

Heat distribution network for heating an d domestic hot water powered by biomass (chips and trimmings) in the district of Mostoles (Madrid). For its first phase, it has already engaged 3,000 dwellings , figures that are expected to reach 6,000 in successive phases.


R2Cities (Castile and León)

Project with the aim of creating and developing replicable construction and design strategies and project management of large-scale districts rehabilitation to achieve nearly to zero energy consumption cities.

It has three demonstration sites located in Kartal (Turkey), Valladolid (Spain) and Genoa (Italy) located in different climatic regions each with their own objectives.

The three sites are managed by their respective municipalities to participate as main promoters of an ambitious project to renovate residential areas, allowing demonstrate that a systematic approach, taking into account the benefits of a combination of technologies like insulation, information technology and renewable energy systems combined in terms of cost-effectiveness and energy efficiency could achieve very good results in terms of energy efficiency and reduction of CO2 emissions.



Positi’f (France)

Specialists in energy rehabilitation of existing buildings and funding in France. They assume roles as:

  • Funding renovations to existing buildings and development of renewable energy.
  • Advisory to condominium and social housing organizations in the different phases of ambitious energy renovation processes.


Bristol City Council District Heating (United Kingdom)

Bristol City Council plans to set up its first District Heating. The program will enable Elena conducting feasibility studies in three different locations.

The main objectives of the program are:

  • Reduce the cost and level of energy consumption for the council and other public sector organizations.
  • Reduce the cost and level of energy consumption for the council and other public sector organizations.
  • Improve energy security and reduce energy poverty
  • Maximize job creation and investment in Bristol and the rest of the region
  • Maximize the benefits that can be invested in new projects for energy efficiency and renewable energy across the city and the West Midlands.
  • Reduce carbon emissions (CO2)

Improve energy security and reduce poverty

There are four branches in investments as part of the ELENA: program that will be carried: district heating at the city level, rehabilitation of public buildings, housing rehabilitation and external insulation facade.


PadovaFIT! (Italy)

The MLEI PadovaFIT! Project aims to stimulate commitment at local level developing a large-scale program of renovation / upgrade housing through measures of Energy Efficiency and Renewable Energy Sources held by an innovative financing system that guarantees all owners to take part.

In its launch phase, expected in 36 months (the scheme is designed to endure beyond the end of the Project Development Assistance), investments will affect 2,250 dwellings, a population of 4,500 inhabitants, which represents more than 2% of the Total population of the municipality.

Including investment projects, the projects aims to a maximum amount of 15,8 million euros with a multiplication factor above 20. In this sense, PADOVA has assembled a team of experienced local private agents (ESCO, a cooperative bank, a nonprofit foundation and an engineering company) ready to risk and invest in the creation of the PadovaFIT !.

The consortium also has a great ability to network operation that will be used to inspire other municipalities to replicate this shining example.


Oxford Total Retrofit OTR (United Kingdom)

The project aims to design a special instrument for the development of energy transport infrastructure at a large scale with low carbon emissions in the city of Oxford and Oxfordshire County.

The funds potentially cover the following types of investment: energy performance contracting in public assets; insurance and financing for the implementation of energy projects for communities; bonds to support the renewal communities.

According to the activity growth of the city and the county community, it will be evident that there is potential to add new projects.

The project will provide the necessary technical capacity to develop products for two different types of investment: energy projects of communities and housing renovation projects at community scale.


Birmingham City Council (United Kingdom)

A project that aims to promote energy saving measures through the Birmingham City Council with the goal to reduce carbon emissions, help fight energy poverty and help create jobs and promote green economy, supported by the European Investment Bank and in order to encourage other similar local authorities in the UK.

As part of the Green Deal, it provides evaluation of energy efficiency improvements in homes or businesses. The project aims to improve energy efficiency and carbon up to 60,000 homes with schools and other non-domestic council properties.

It provides people affordable ways to insulate their homes, installing more efficient heating systems and to adopt renewable technologies such as solar.
