£20m plans for green heating network at Millerhill

A £20 million green energy project, which will have the same carbon impact as taking 1200 cars off the road, is set to be built in Millerhill.

Midlothian Council has paired with Swedish state energy firm Vattenfall to bring a district heating energy centre to the county.

The centre, which was initially planned to be built alongside the new Shawfair education campus, is now being considered for Millerhill, where it will sit beside its recycling and energy recovery centre (RERC) which will provide fuel for the heating network.

The local authority was asked to rule on whether the proposed centre, which will be built in woodlands next to Millerhill Marshalling Yard, would need an environmental impact assessment before a planning application could be considered. Although the proposed building is described as 12 metres high and 50m by 38m in size, and will require pipes to travel alongside woodlands to Shawfair, the council ruled it did not require the assessment.

A Vattenfall report lodged with the council acknowledged that the building would be in woodland, but said: “The proposed development site is located in woodland noted on the Native Woodland Inventory which will be cleared for building works, informed by a tree survey and retaining existing trees where possible.”

A map showing the planned route for pipes from the building to Shawfair shows them underground and running adjacent to a strip of woodlands.

Midllothian Council has signed up to a 40-year deal to provide heating for new public buildings in Shawfair after hailing its potential to reduce CO2 emissions.

The main source of energy to produce heat is expected to come from the recycling centre, however, a back-up boiler will be in place in case of disruption to the supply.

The report said “the back-up boiler is to be electric-powered and required less than 876 hours per year, only during periods of maintenance or outage from the RERC facility”.

The council said that the district heating network is expected to save “over 2,000 tonnes of CO2 per year, the equivalent of taking 1,200 cars off the road”. Deals will be made with Shawfair developers to connect the network to homes and businesses in the new town as it develops.

Midlothian Council said the network project involved a £20m investment with up to £7.3m coming from the Scottish Government’s Low Carbon Infrastructure Transformation Programme.

The local authority’s hope for Shawfair is that eventually up to 3,000 homes will be connected to the local heating network.
