SCS: One NottinghamAn agenda for change over the next decade.
It is a strategy for jobs and prosperity, for better neighbourhoods and for
strong and aspiring families, spread across 6 priorities of: World Class Nottingham
Neighbourhood Nottingham
Family Nottingham
Working Nottingham Safer Nottingham
Healthy Nottingham
Green Nottingham
A cross-cutting aim to move Nottingham into a lower carbon future,and live within our environmental limits. This has implications for howwe deliver every action programme, with a need to reduce carbonemissions over time and respond to climate change.

Nottinghams Strategic Sustainability Targets:
Reduce the citys carbon emissions by 26% of2005 levels by 2020
20% of the Citys energy from renewable orlow/zero carbon sources by 2020
e uce t e ty s energy consumpt on y 5% Eradicate fuel poverty by 2016
Increase the recycling of waste to 50%
Build a green collar economy

Increase Sustainable Energy Generation
Based on the Governments National
Renewable Energy Strategy targets,Nottingham will meet its 20% sustainable
energy target through:
2% (37GWh) generation from small
Nottingham currently generates 11.45% of our own
heat and power from gas CHP (combined heat and
power) and renewables
scale sources 12% (342.7GWh) generation from
renewable heat sources
reducing energy demand by over
25%through energy efficiency measures

Increase Sustainable Energy Generationthrough:
Action Plan Highlights
More than doubling the size of the Citydistrict heating network
- Wind Power- P.V.s Solar Panels
- Hydro Power- Heat Pumps
Significant capacity of new biomassCHP plant with associated district heating
Consideration of a City anaerobicdigester

Combined Heat and Power The Scheme generates
over 40,000 MWh of
electricity using 3 turbinegenerators The power is used
internally (including EfW
plant), sold through aprivate wire network orspilled to the grid
Approximately half is soldthrough the private wirenetwork guaranteeinguninterrupted supply

Expansion Plans Planning Consent for a 3rd Line at
EfW plant has been grantedincreasing capacity by 100,000tpa
Anticipate work completed in 2013
Recently awarded 1.5m grant fromthe Homes and CommunitiesA enc Low Carbon infrastructure
Fund (LCIF) to extend the DHS tothe Southside regeneration area.
We now have a new applicationwith the HCA to expand on to theEastside
Require c.7 million of investmentin Heat station to build new turbine

Securing Customers on CHP If the property is a RTB the City Council provides a covenant in the
deeds that the new owner keeps the existing heatingequipment/connection to the property and restricts the use of other
forms of heating.
If they are a council tenant then they are signed up on occupancy toa supply agreement.
The Merton Rule requires that for new commercial buildings over1,000 square meters, at least 10% of their energy needs must bemet through on-site renewable energy equipment, a connection tothe DHS easily enables developers to comply with this requirement.
Part L of the planning regulations made it almost impossible toinstall electric heating and have a reasonable sized glazed area,whilst achieving the required SAP value. This encourageddevelopers to seek connections to the DHS.

Waste Composition Analysis
35%+ organics suitable for AD BUTwe are mindful of biomass content ofEfW waste streams for ROCs
Other technology choices for sustainable energygeneration Dependent upon security of waste supply where shouldthis risk sit?
Security of customer base domestic/ commercial? Business case incentive payments FITS/ ROCS/ RHI Other funding opportunities ERDF/ ELENA Funding Soft market testing

Conclusions Lead from the front Time to believe, then ACT
Energy, waste and climate change inter-dependent
Join-up strategic thinking then ACT
Waste is a resource to deliver low carbon energy
Partnerships and alternative business models
Local Authority Carbon Framework
