Vattenfall partnership to offer low-carbon heating in SE London

10,500 new homes in south east London could be heated through a new centralised network rather than conventional gas or electric heating in each property. Vattenfall has secured the right to capture heat from the Cory Riverside Energy’s (Cory) energy from waste facility at Belvedere, and will develop a heat network that could supply local households.

10,500 new homes in south east London could be heated through a new centralised network rather than conventional gas or electric heating in each property.

Vattenfall has secured the right to capture heat from the Cory Riverside Energy’s (Cory) energy from waste facility at Belvedere, and will develop a heat network that could supply local households.

The project raises the real possibility that tens of thousands of properties could be provided with low-carbon heat via a wider area network, reducing carbon emissions by 80-90% compared to using conventional gas boilers in each household.

Vattenfall Heat UK will work with Cory on an application for funding from the Government’s Heat Networks Investment Project. Vattenfall will design the heat network and, if the project moves to the construction phase, lead the construction of the heat network infrastructure, operate the network, and supply and look after residential and commercial customers.

Vattenfall’s design will introduce a new fourth generation, low temperature district heating network which will:

• Improve performance and reduce lost electricity revenues of the energy from waste facility;
• Use lower temperatures to reduce network heat losses, meaning more efficient operational cashflows;
• Result in lower capital costs on pipework, and;
• Be flexibly developed to enable future developments to connect to high-temperature legacy systems – meaning the network can be extended to link to existing properties, further reducing carbon emissions.

Vattenfall is the largest operator of district heating networks in western Europe, providing the infrastructure for low-carbon heat to 1.7 million households across Sweden, Germany, and the Netherlands.

Heat networks are essential to decarbonising heating in domestic and commercial properties, and to meeting the UK’s target of net zero emissions by 2050. They supply heat from a central low or zero carbon energy source, such as waste heat or local generation, to homes or businesses through a network of underground pipes. This means there is no need for individual boilers or electric heaters in every building.

The proposed network in East London could initially provide heat to 10,500 homes earmarked for construction in the vicinity of Cory’s site. However, the design will allow for thousands more properties to be added as they are constructed in the future, unlocking the potential for a much wider network.

Vattenfall’s vision is to create an East London Heat Network, extending approximately 30km across four London Boroughs (Bexley, Greenwich, Newham, Barking and Dagenham). It will supply low and – ultimately – zero carbon heat to both existing properties and new developments by re-using heat that is currently being wasted.

Individual developments would connect to the East London Heat Network as they are built. The entire project is estimated to be able to supply the equivalent of 75,000 homes, although in reality it would link up to residential, commercial, retail, and industrial buildings.

Adriana Rodriguez Cobas, Regional Director, South for Vattenfall Heat UK, said:

“This is a landmark moment not only for Vattenfall Heat UK, but also for the drive to cut emissions from homes.

“We’re very proud to have been appointed by Cory Riverside Energy to capture the waste heat from their plant. We can use that heat to help local households keep warm without having to worry about the size of their energy bill, or whether they’re damaging the planet if they turn the heating up.

“This opportunity extends beyond the first phase of housing earmarked for development in Bexley. Vattenfall’s expertise means we can design the system so that future homes and business properties can also be linked up to the same heat network, without needing to go through the disruption and lengthy process of designing a bespoke network for a separate construction project. This is exactly the kind of long-term vision that Vattenfall has for district heating in the UK, and shows the potential of what can be achieved when multiple partners work together towards shared goals.”

Noah Nkonge, Head of Partnerships at Vattenfall Heat UK added:

“Heating our homes and businesses currently accounts for around 20% of UK greenhouse gas emissions1. The Cory project is a great example of what can be achieved by multiple organisations working towards fossil-fuel free living.

“Installing low-carbon heating technologies requires a strong partnership approach between planning authorities, energy specialists and developers, along with a long-term vision to achieve environmental and economic ambitions. We’re ready to use our expertise to work with national and local authorities on a regulatory framework which enables this technology to be rolled out at scale, delivering the infrastructure needed to meet decarbonisation targets.”

Commenting on the appointment, Andy Pike, Director of Strategic Infrastructure Development at Cory Riverside Energy, said:

“We are pleased to be working with Vattenfall on our heat network. Their skills and expertise will help us provide local homes and business with a clean, renewable and reliable source of heat.”

“That way CO2 emissions are falling significantly. Also, individual air conditioning systems in buildings – and their resulting on-site heat emissions – are no longer needed. The district cooling thus counteracts the summer heat bell over the city center and the overall warming of Munich.”

Preliminary construction activities have started in late March in a densely built area close to the inner city. SWM expects the project to be completed by the fall of 2021.
