Decision:
Resolved: to note the contributions to the
review.
Minutes:
5.1 Peter
North (Programme Manager, Sustainable Energy, Greater London Authority) introduced a presentation;
the following key points were noted:
- A third of
London’s CO2 emissions were generated by
heating.
- More energy was used
to heat buildings in the UK than was used for transport or
electricity generation. So in order to deliver reductions in
CO2, in buildings it would be necessary to increase the
energy efficiency of buildings and how the energy is
supplied.
- London had a target
of 60% reduction in 1990 levels of CO2 by 2025 alongside
a target to supply 25% of its energy from local decentralised
sources.
- The carbon content of
electricity generation would be an important part of future work in
this area.
- A public role was
required in order to enable district energy.
- There were three main
categories of decentralised energy projects: single sites utilising
small/medium CHP systems; multi-site mixed use schemes: area wide
transmission networks with extensive heat pipe systems.
- In 2011 the GLA
carried out a decentralised energy capacity study. It was found
that London had more capacity potential than the 25% target for
decentralised energy set by the Mayor.
- The London Plan
contains a range of specific policies to promote the development of
decentralised in new developments.
- Insulation was the
first and most important part of ensuring the efficient use of
energy.
- Generating energy
from renewables had proved difficult in the urban
environment.
- Densely developed
areas were the most suitable for decentralised energy
schemes.
- Area planning was an
important part of enabling the future connection of new
developments to existing networks.
- London boroughs could
be involved in the delivery of decentralised energy projects in a
number of different ways. They might choose to deliver their own
schemes, or they might only act as a planning authority,
facilitating delivery by others.
- Development of energy
master plans was a long process taking around six months from start
to finish, but work had taken place in 10 boroughs to achieve a
coordinated policy.
- The GLA’s EU
funded technical, commercial and financial advisory services had
helped develop a £300m pipeline of projects. The advisory
support was running down and the GLA are proposing a successor
arrangement that will operate until 2020.
- Two major projects
were- Gospel Oak Hospital, and Islington Heat and Power scheme, the
later connecting 850 dwellings providing 10% lower energy
bills.
- Phase two of the Islington scheme
sought to use waste heat from the underground and other
sources.
- There were four
energy from waste plants in and around the city, that could provide heat for tens of thousands
of homes.
- SELCHP was finally
providing heating to estates in Southwark after 15 years of
operation as a power-only energy from waste facility..
- The future of heat
networks would be to utilise heat lost from other processes - each
would require technical availability and economic case.
- In order to meet the
government’s carbon targets, decentralised energy and
communal heating would need to be part of the solution.
