Dublin first major urban centre in Ireland to get district-heating scheme

Tallaght in Co Dublin is to become the first major urban centre in Ireland where many buildings will soon be availing of a very cheap source of energy known as district heating.

In this instance, the excess heat that will be used to warm the buildings will come from a large data centre in the area being run by Amazon Web Services (AWS).

District heating is common in many large cities around the world, where waste heat from local industry, power stations or incinerators is used to heat other premises. This option is availed in very few instances in Ireland, although the programme for Government commits to scaling up its deployment.

South Dublin County Council (SDCC) has established Ireland’s first publicly owned not-for-profit energy company – Heatworks – with the support of AWS and the Finnish-owned energy company Fortum eNext to provide low-carbon heat to local buildings.

It will operate the Tallaght District Heating Network, which when completed is predicted to reduce carbon emissions in the local authority’s area by nearly 1 500 tonnes per year.

The network will use excess heat from the recently completed data centre to provide low-carbon heat to a mix of public sector, residential and commercial customers.

AWS is providing recycled heat free of charge under its broader sustainability commitments.

Fortum, an energy supply company with extensive district-heating experience throughout Scandinavia and eastern Europe, was contracted to carry out the design, installation and operation of the network.

According to Heatworks, the network’s supply of low-cost, low-carbon heat is expected to attract more innovative businesses and development to Tallaght town centre, and facilitate educational programmes and start-up opportunities in renewable energy solutions, as well as helping to mitigate fuel poverty.

The project is partly funded by the EU’s Heatnet programme promoting carbon reduction through district-heating in Europe’s northwest. It is also receiving EUR4.5-million from the Government’s climate action fund and direct funding from SDCC.

By 2024, the heat will also be supplied to nearby developments recently given planning permission, including affordable housing units and student accommodation.

SDCC chief executive Daniel McLoughlin said: “The Tallaght District Heating Network shows how public-private collaboration using well-established district-heating technology can construct a system to recycle heat from an Amazon Web Services data centre to meaningfully contribute to helping Ireland achieve its 2030 sustainability targets.”

He believes this scheme could become a template for other districts across Ireland. “We look forward to future collaborations as south Dublin county moves towards a low-carbon future,” he added.
