The London Heat Map (www.londonheatmap.org.uk, 2011)
The London Heat Map is an interactive tool that allows users to identify opportunities
for DE projects in London.
- It is owned by the GLA since 2011
- It builds on the 2005 London Community
Heating Development Study
- It is in a user friendly format using an
interactive GIS system
- It provides spatial intelligence on factors
relevant to the identification and
development of DE opportunities, such as
major heat loads and supply plants, heat
networks, DE clusters, OAPFs, etc.
- It is publicly accessible to anyone with an
interest in DE
The heat mapping exercise has been
completed for the London Boroughs in
March 2012. 31 Heat Map reports are
available for download.
Decentralised Energy Masterplanning Programme (2011)
The Mayor of London is providing financial and technical support to London
Boroughs in the production of local Energy Masterplans.
Masterplans are developed to:
-Identify new DE opportunities in an area
-Set out a long-term vision for the heat networks growth
-Develop planning policies to promote heat networks and the connection of new
developments to those networks
Masterplans must include:
-Phased construction of new
developments
-Initial proposals for pipe routes and
plant locations
-Outilne economic and environmental
impacts of their implementation
To date, 10 Energy Masterplans have
been completed and are available to
download at the London Heat Map
website, whilst 5 are underway.

Decentralised Energy Project Delivery Unit (2011)
DEPDU provides technical, financial and commercial advisory services to help
others develop and bring to market larger scale DE projects
-€3.3m funding (90% from the European Commission’s ELENA technical assistance
facility, 10% from the GLA)
-Private and public sector support
-Focus on heat network schemes supplied from CHP and sources of waste heat
-Targets: projects with total investment of £60.5m to market by July 2014 (leverage
ratio 25:1)
To date the GLA has supported almost £40m of DE projects to market. The
programme is actively supporting a pipeline of 18 DE projects, with a total
investment potential of over £150m.
Case Study – Gospel Oak DH (LB of Camden)
- Heat network supplied by waste heat from a new 4.6MW gas turbine CHP
installation at the Royal Free Hospital
- 3.5MW GT heat recovery system, 1.3km heat network
- System supplies existing housing estates (~ 1,500 units)
- CAPEX: £5.7m
- Project commissioned in 2012
- CO2 savings: 2,890 t/year
- DEPDU role: assist LB Camden with initial feasibility, design and energy supply
contract preparation
Case Study – South Kilburn DE (LB of Brent)
- Regeneration project
- 2,400 new homes and related facilities and
infrastructure
- The LB of Brent is procuring a £15m sitewide heat network through an ESCo
concession agreement
- OJEU notice issued in 2011 and 3 bidders
selected to be taken to the Invitation to
Tender (ITT) stage
- DEPDU role: assisting the LB of Brent with
initial feasibility study, ESCo procurement
process and development of a concession
contract
- Expected construction start date: 2015
- 3.1km heat network
- 1.5MWe / 2.5MWth CHP
- CO2 savings: 835 t/year (estimated)
Case Study - Lee Valley Heat Network (North London)
Pilot Projects – Islington’s Bunhill Phase 2
EU co-funded project, CELCIUS, aimed at demonstrating innovative solutions of
using low temperature secondary waste heat to supply new and existing homes.
Background information:
-£3.8m CAPEX (£1.1m EU / £2.7m
Islington)
-GLA provides PM and technical
support
Waste heat recovery:
-3 UKPN electrical transformers, oil
cooled (~ 40-50°C)
-LU mid-tunnel ventilation shaft, air (~
15-25°C)
Objectives:
-Connect 500 existing homes and
other new homes to the Bunhill heat
network
-Demonstrate technical viability and
disseminate results
Licence Lite
Licence Lite is a simplified version of a standard electricity supply licence to enable
“small” generators to enter the electricity supply market.
-Started in 2009 when Ofgem published proposed changes to the standard
conditions for electricity supply licences
-Small generators can supply their electricity retail to any premises connected to the
public electricity distribution system  prospect of earning higher returns on the
electricity they export
-Example: export tariff ~4.5 p/kWh, retail price ~ 12-17 p/kWh
-Objective: to enable CHP DE schemes to earn greater over-all returns on their
energy generation thus becoming financially viable and capable of attracting
investment.
In March 2014, the GLA became the first authority in the country to apply to
Ofgem for a Licence Lite.
The GLA will:
-Buy excess electricity produced by London’s boroughs and public bodies
-Sell it on, at cost price (~10 p/kWh < retail price), to other public sector
organisations, such as Transport for London, the Met Police and NHS hospitals.
-Scheme could be extended it to include private sector energy producers.
London’s Zero Carbon Energy Resource (2013)
This study examines the availability and cost of ‘secondary’ heat sources in London
and issues associated with their integration with heat networks.
Focus:
-Builds on Decentralised Energy Capacity Study
-Waste heat arising as a by-product of industrial
and commercial activities (e.g. data centres);
-Heat that exists naturally within the environment
(air, ground, water).
Objectives:
-To inform policy development and the market on
the likely technical and economic conditions in
which these sources may be viable;
-To identify emerging project opportunities.
Conclusions:
-24% of London’s heat demand could be
economically met by these sources when
distributed via local heat and power networks.
