Tour of the Tallaght District Heating Scheme

Come on a tour of the site of the Tallaght District Heating Scheme, which is the first large-scale district heating network of its kind in Ireland.

The scheme operates under Heat Works as the country’s first not-for-profit energy utility, owned by South Dublin County Council. This scheme makes a significant contribution to reducing carbon emissions in the area, saving almost 1,500 tonnes of CO2 each year and establishing Tallaght as a leader in innovation in the area of climate change.

Tour Starting Point: Please meet directly outside the 10 minutes in advance of the tour starting. You can find the exact location by clicking .

This tour is taking place as part of Dublin Climate Action Week, which runs from the 11th - 17th May 2026.

Background to the Tallaght District Heating Scheme

District heating is a network of highly-insulated pipes that delivers low-carbon heat from a central energy source to provide space heating and hot water to the buildings connected to the network. In the case of the Tallaght District Heating Scheme, this project delivers a high level of innovation, as waste heat from the nearby Amazon Web Services (AWS) data centre supplies the heat to the network.

The system was officially launched in April 2023 and the first phase of this project supplies heat to existing and new local authority buildings, buildings within the TU Dublin Tallaght campus and to 133 households in the cost-rental Innovation Square apartment complex. There is also potential for many other local buildings to connect in the future, such as other new residential developments, Tallaght Hospital and others.

The tour will be conducted by the Dublin energy agency Codema on behalf of South Dublin County Council.

Codema has helped South Dublin County Council to secure funding of almost €4.5 million for the Tallaght District Heating Scheme through the Government's Climate Action Fund, as well as support from the Interreg North-West Europe HeatNet NWE project and the Sustainable Energy Authority of Ireland.
