Multiplex is the first and only contractor in the UK with its own solar farm and, from 1 April 2025, four major construction projects it is delivering in Central London – including New Zealand House, One Exchange Square and Bankside Yards (Building 2) - will be powered by green energy offset under the PPA. It is Multiplex’s intention that all new projects will also fall under this arrangement too, as part of a long-term, 15-year commitment and partnership with Ampyr Solar.
Through securing a long-term supply of renewable power, this will contribute to zero onsite emissions and a reduction of Scope 2 emissions (indirect emissions from purchased electricity). Additionally, Multiplex aims to attain net zero building operations, zero emissions transport, and zero avoidable waste by 2030.
The Northwold PV project boasts a generation capacity of 10 MWp, covering 19 hectares and comprising 16,380 solar panels. The installation will generate approximately 11,448 MWh per year, supplying over 4,200 households with green energy and saving an estimated 3,600 tons of CO₂ emissions annually. A key feature of this project is the integration of a 7.5 MW battery storage system, which will be managed by GridBeyond. This system plays a key role in incorporating more renewable energy into the grid and providing support during peak demand periods.
“Northwold PV going online is a significant step forward in reducing our carbon emissions, delivering actions and not merely words in support of the decarbonisation of the UK construction industry” said Tom Marke, Regional Director, Multiplex UK. “Multiplex’s self-generated renewable energy will directly lead to verifiable emission reduction and renewable energy production, supporting the UK’s National Grid decarbonisation goals.”
