Sustainable Communities Strategy:

One Nottingham

CITY

Nottingham is starting from a solid position:

Nottingham Declaration on Climate Change

Transport Planning Authority of the Year Tram

LATS Compliant through to 2020

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.


5/24

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


8/24

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

Developing a Waste Strategy A Waste-Less Nottingham:

Waste Strategy Drivers:

- Carbon reduction

- Waste Minimisation

- Improved recycling- Improved energy recovery

- Zero landfill

- Economic resilience

District Heating Energy from Waste Eastcroft Energy from Waste plant operating sincesince 1972, originally by National Coal Board

Municipal Residual Waste Contract with WRG whoacquired the incinerator in 1992

160,000 tpa City delivers 80,000+ tpa (55% ofMSW)

62% biomass content of waste stream ROCs 2 separate lines extensively renovated in 2009

EfW boilers rated for 52t/hr of HP Steam at 372o

C Provides 375,000MW of High Pressure steam

Drug Co. Ltd Converted to EfW in 1972

Enviroenergy Ltd since 1995

of Energy and Climate Change (DECC)CHP QA programme, rated as goodquality.

Offsets approximately 27,000 tonnesof CO

otherwise be produced by alternativeuse of fossil fuels

Combined Heat and Power 65km of heating pipes beneath the streets

of Nottingham

Heating mains rated for temperatures upto 140C at 10.5bar ~ 95C

Hot water leaves Heat Station in 18diameter pipes, reducing down to 0.5

On average we distribute annually around144,000MWh


16/24

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

District Heating Expansion


20/24

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.

Biomass CHPNottingham City Hospital Currently burns 8,000

tonnes of coal per annum

Annual CO2e emissionsof 18,700 tonnes , equalto 1% of total carbonoo pr n o e c y

Currently assisting withfeasibility study to convertto biomass CHP across

hospital campus Sourcing suitable MSWstreams and importingcommercial biomass

Together with Queens MedicalCentre provides health care toover 2.5 million people

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


23/24

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
