no connection to a Decentralised Energy Network. The preferred energy strategy shall be
enacted, unless it is not reasonably possible to connect to a Decentralised Energy Network,
in which case the alternative energy strategy shall be enacted.
3.0.19 Part A of the policy requires developments to have the ability to connect to a DEN, which
means that developments have the ability to be connected to a network if/when such a
network becomes available in the future, rather than necessarily connecting at the time
of construction. Whether minor developments can reasonably be designed to be able to
connect to a DEN will be assessed by the council, taking into account a range of factors,
including size, location, use and design of the development. Specific design standards
to enable connection and future connection will be set out in the Sustainable Design SPD.
3.0.20 All developments within 500 metres of an existing or planned DEN, or minor developments
within 100 metres of an existing network, are required to submit a feasibility assessment
of connection to that network, to determine whether connection is reasonably possible.
The council, or relevant Energy Service Company, will provide relevant information to
inform the feasibility assessment, including an assessment of the approximate cost of
connection. Where connection is not considered technically possible or is not considered
possible for non-technical reasons, including financial viability, the alternative energy
strategy is required to be enacted. Feasibility assessments should consider a range of
factors, including:
d. the size of the development, and the heat load and energy demands;
e. the distance to network pipes;
f. physical barriers e.g. roads and railways, and
g. other developments in the vicinity that may also be required to connect to the network.
3.0.21 Where connection to a network is deemed to be reasonably possible, the anticipated CO 2
reductions to be achieved by connection to the network shall contribute to the total CO 2
reduction target, which shall be at least 50%, compared with total emissions from a building
that complies with 2006 Building Regulations Part L. The CO 2
reductions anticipated from
connection shall be assessed and agreed by the council. Other measures proposed to
contribute to the relevant CO 2
reduction target shall be complementary with network
connection technologies and/or with SHN and/or CHP technologies, in order to achieve
maximum reasonable carbon dioxide reductions.
3.0.22 Where connection is not considered reasonably possible, due to technical or non-technical
reasons, including financial viability, an alternative energy strategy is required to be enacted.
This strategy should achieve at least a 40% reduction in CO 2
emissions, compared with
total emissions from a building that complies with 2006 Building Regulations Part L.
