Shawfair Edinburgh.
Consisting of over 500,000 litre’s of chemical free water, Shawfair is one of the UK’s largest heat networks to go chemical free.
A £30 million low-carbon heating network for the new Shawfair Town near Edinburgh, Scotland has been developed by Midlothian Energy Limited.
A joint venture between Vattenfall and Midlothian Energy Limited sees waste energy being utilised from the Millerhill Recycling and Energy Recovery Centre (RERC), where non-recyclable waste is incinerated to produce steam, which is then used to drive electrical turbines to create electricity which is exported to the grid.
The residual steam produced during the incineration process is utilised in the new Energy Centre. The heat generated through steam is then transferred to Shawfair Town via the new state of the art energy centre. Hulley & Kirkwood were the principal design consultants for the project, with the installation being completed by FES.
Utilising their offsite prefabrication facilities, FES fabricated much of the project off site under controlled conditions before being transferred to site for installation.
An advanced underground pipe work network installed by PPSL District Heating LTD with the initial phase of the network supplying 3000 homes plus education and retail properties.
Various substations are installed throughout the heat network, where SWEP Brazed Plate Heat Exchangers have been utilised. The energy centre has been designed with a fall back up plant, consisting of electric boilers from PARAT and Biomass boilers from HOVAL. The initial phase is expected to save over 2,500 tonnes of C02 per year.
A £120m business plan for further development has been approved by Midlothian Energy Limited for further expansion of the heating network where the heat network will rise to 10,000 homes.
