A Bridgend Council project to pump naturally-heated Water from an old coal mine has received a £6.5M grant.
The £9.4M scheme from the former Caerau colliery aims to heat 150 homes and would be a UK-first.
The grant is to develop and install technology to pump water from a depth of 230m (750ft) which would be heated by the earth to around 20.6C (70F).
Construction work is expected to start in 2020 with the first 150 homes heated by winter 2021. The scheme could heat up to 1000 homes in Wales’ fifth most deprived ward. The hope is that the scheme will save the consumer £100 a year on energy bills.
A feasibility study is ongoing until the end of February with the British Geological Survey testing the temperature, chemistry and volume of water available.
The total cost for the project is about £9.4M, but Bridgend Council still needs to raise £700,000 to get the project into its next phase. The Welsh European Funding Office provided the £6.5M grant £2.2M came from the UK and Welsh Governments.
Mr Young, cabinet member for communities, said:
“It’s a very prestigious project and I am proud it’s happening in Bridgend.”
“We know the technology exists, we know it’s been proven, we know the system works and that’s why I’m so excited it’s being brought into Bridgend.”
Cabinet Secretary for Energy Lesley Griffiths said:
“This is a cutting-edge model of generating a clean source of renewable energy, drawing on the legacy of our coal mining heritage.”
