The International District Energy Association (IDEA) commends London Mayor Boris Johnson for guidelines to support the delivery of district energy schemes in the capital.

The International District Energy Association welcomes the 'District Heating Manual for London,' which provides practical guidance for developers, network designers and planners with the aim of creating a consistent framework for delivering efficient, interconnecting, district heating networks. It is also designed to help guide local planning authorities so that future expansion can be further optimized for greater integration of resources. The document, developed by the Greater London Authority in collaboration with Arup, supports a range of initiatives to promote Mayor Boris Johnson’s target to achieve 25 per cent of London’s energy supply from decentralized energy sources by 2025.

“IDEA is pleased to see one of the world’s major cities recognizing the economic value and environmental importance of thermal energy (heat) in planning, managing and optimizing district energy infrastructure for a more resilient local economy," said Rob Thornton, President & CEO of IDEA. "This District Heating Manual will provide a consistent framework to support increased implementation of district energy systems across the city of London. As a proven, highly effective approach to reducing greenhouse gas emissions and improving energy efficiency, district energy systems also offer the advantages of enhanced infrastructure resiliency. As mayors worldwide face growing concerns with climate change adaptation and infrastructure hardening due to more severe weather events, the guidance in the District Heating Manual for London will be a useful template for urban planners and civic leaders in cities large and small across the globe.”

According to the Greater London Authority, London is experiencing a significant increase in infrastructure investment in decentralized energy schemes. City Hall is currently supporting the delivery of schemes valued at more than £300m where the principles of the manual are being applied. The District Heating manual, the first of its kind in the UK, is designed to be a 'live' document that will be updated. It can be accessed here:

The International District Energy Association (IDEA) is an independent, non-profit industry association formed in 1909 with headquarters in Westborough, Massachusetts which represents the interests of over 1,600 members from 26 countries involved in operation, design, construction and optimization of district heating, district cooling and CHP (cogeneration) systems, with a majority of members in North America, as well as Europe, Middle East and Asia Pacific.
