Our Network

Heat Works is Ireland’s first not-for-profit energy utility, fully-owned by South Dublin County Council. The Tallaght District Heating Scheme is the first large-scale district heating network of its kind in the country.  Phase 1 of the scheme began construction in May 2021 and became operational at the end of 2022.

District Heating Scheme

The Tallaght District Heating Scheme will make a significant contribution to reducing carbon emissions in the area, saving almost 1,500 tonnes of COeach year and establishing Tallaght as a leader in innovation in the area of climate change.

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.  The Tallaght District Heating Scheme delivers a high level of innovation, as waste heat from the nearby Amazon data centre will supply the heat to the network.  During normal operation, heat demand will be 100% covered from the data centre waste heat.

The first phase of this project connects existing and new local authority buildings and the TU Dublin-Tallaght campus to this local district heating network.  There is also potential for the new residential development at Belgard Gardens, which will be home to more than 3,000 people, to connect to the network at a later phase.

South Dublin County Council and its energy agency Codema have worked together to secure funding of almost €4.5 million for the 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.
