Excess heat from the revamped Birmingham New Street station’s combined heat and power (CHP) unit is being exported into the Second City’s district energy scheme.
The project involves Network Rail, Birmingham City Council (BCC), Cofely and sustainability consultants, Anthesis-SecondNature.
The scheme will see 1.5km of district heating pipework installed across the station and in the city centre. This will enable excess heat produced by a new CHP unit to be exported to the Birmingham District Energy Scheme, which is owned and operated by Cofely in partnership with BCC. It supplies heat to offices and other buildings in the city, including Aston University and the National Indoor Arena.
Network Rail’s £600M refurbished New Street station is three times the size of the old station and will require more electricity. This will be partly provided by the CHP unit.
The connection of the station to the Birmingham District Energy Scheme enables excess heat produced by the station’s CHP plant to be pumped to offices and buildings around the station.
This is the first time that a CHP plant has been used in a Network Rail managed station.
As a result of the initiative, the Birmingham New Street station will reduce its energy bills and achieve a lower carbon footprint per square meter, potentially cutting carbon emissions by up to 3,000 tonnes per year when combined with the wider scheme.
