Silvertown confirmed as first UK home for E.ON’s pioneering ectogrid™ low carbon energy network

• Heat pump-based system provides 88% lower emissions than gas boiler alternative 
• Low carbon network will serve more than 6,000 homes as well as leisure, cultural and community facilities and workspaces at the Silvertown development in East London

E.ON and Lendlease have signed an agreement to develop a pioneering low carbon energy network to serve about 6,500 new homes and business properties at Silvertown in East London.

The 760,000 sqm Silvertown site will be the UK’s first development of E.ON’s pioneering ectogrid™ system, an energy sharing heat network based on heat pump technology that, once complete, will save approximately 4,000 tonnes of CO₂ a year – 88% lower emissions than from traditional gas boilers.

Silvertown is being transformed as a vibrant new heart for the Royal Docks and a new visitor destination for London. Plans include the restoration of the iconic Millennium Mills and construction of about 6,500 homes alongside next-generation workspace, shops, restaurants, bars and a water sports centre. The regeneration of the area will deliver significant opportunities for the local community, creating more than 6,000 new jobs.

The core principle of ectogrid™ is to provide heating and cooling by first using existing energy sources available locally, such as air, water or ground. Each connected building sends excess heating or cooling to other buildings as needed, and by sharing, balancing, and storing energy in rotation, ectogrid™ uses all available energy before adding any ‘new’ energy, drastically reducing consumption, costs and environmental impact.

Chris Norbury, Chief Executive of E.ON UK, said: ”Silvertown is a huge milestone for UK developments as this is the first ectogrid™ for Britain. It’s fantastic that we can bring this to life in such an iconic redevelopment area as the Royal Docks. Allied to our recent investments in Uskmouth, Port of Liverpool and our geothermal energy solution for the Queen's Medical Centre in Nottingham, this is yet another example of E.ON investing at scale in the UK’s energy future.

“Making energy more affordable and sustainable is a critical element of growing the UK economy and it cannot be achieved without an ambition to deliver huge societal benefit too. With our key role as playmaker to make new energy work, over the next four years we will continue our track record of investing in the UK to create even more opportunities for people across the country and deliver innovative change that will bring real world benefits felt far beyond the world of energy alone.” 

Ed Mayes, Development Director for Silvertown, said: “Sustainability is at the heart of everything we do at Lendlease and a low-carbon energy network is central to our vision for Silvertown. We’re delighted to extend our relationship with E.ON and to be working with them to deliver their pioneering ectogrid™ in the UK for the first time. Unlocking this complex site is the result of close partnerships – including the London Borough of Newham, the GLA, Homes England, and The Guinness Partnership – and in E.ON we have secured an equally strong partner to support us in delivering on our zero-carbon ambitions."

Tom Copley, Deputy Mayor for Housing and Residential Development, said: “Silvertown is a key scheme as we work to bring East London’s Royal Docks back to its former glory and I am pleased we have been able to embrace this innovative approach to district heating that will supply low carbon heat to this important site while ensuring bills are more affordable.

“The Mayor is determined to move London towards a greener future and aim to deliver net-zero carbon emissions by 2030. Schemes like this prove that it is possible to deliver the housing and the low carbon heat that London needs by embracing innovative approaches that help tackle the climate emergency and create a greener city for all Londoners.”

Darren Makin, Director of Community Wealth Building at Newham Council, said: “Silvertown's adoption of E.ON’s ectogrid™ marks a significant step forward in our commitment to a more inclusive and sustainable borough. Last year we launched the UK’s first Just Transition Plan, an urgent blueprint for us and our partners to prioritise cutting CO2 emissions, as well as addressing the unequal impacts of climate change on society.

"This pioneering low-carbon energy network will not only drastically reduce emissions but also enhance the quality of life for our residents and create a healthier, more prosperous community. The London Borough of Newham is proud to support this initiative, which aligns perfectly with our vision for a greener, more sustainable future."
