Shawfair District Heating Network

Project Role: Commissioning Manager on behalf of M&E Contractor / Commissioning and Water Treatment Engineers

Project Information

The initial phase of the MEL heat network will serve Shawfair Town, one of Scotland’s largest new development projects, a 15-minute train ride from Edinburgh city centre. As well as the construction of new homes, it will have three new schools, extensive cycling and walking networks and large areas of public open space – as well as retail, business and community facilities.

The MEL heat network will capture low carbon heat from the Millerhill Recycling and Energy Recovery Centre – an energy from waste plant operated by FCC Environment. The main energy centre will have the potential to heat up to 10,000 homes equivalent. 

As the network expands in Midlothian to cover more areas and supply more properties and developments, we plan to connect other waste heat sources including heat captured from mine workings.
