1. What is CHP and District 1. What is CHP and District HeatingHeating

Page 5: The Southampton City District Energy Scheme  a partnership between

WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS

Combined Heat & Power (CHP) - recovery of heat produced when generating electricity (usually wasted)

What is CHP?

Page 6: The Southampton City District Energy Scheme  a partnership between

WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS

CHP - operates at 70-85% efficiency compared to typical power stations 25-35%.

CHP - Replacing central power stations with more efficient local generation

What is CHP?

Page 7: The Southampton City District Energy Scheme  a partnership between

WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS

• On site heat, chilled water and electricity distribution network• Used for distributing energy from boilers & CHP• Current heating piping systems - heat losses are 1°C per km• Reliability of current piping systems - 100%• Large sections could use plastic PE-X Pipes

What is District Energy ?

The Cornerstone The Cornerstone – The Joint Co-operation Agreement– The Joint Co-operation Agreement

The Scheme has always had cross party support - the first step was to sign a Joint Co-Operation agreement - 1987 - first in the UK pre-dating PFI

This committed Utilicom to:– Developing a district heating scheme in Southampton initially based around geothermal

energy

– Sell heat to Council buildings with agreed savings

– Provide all necessary funding and technical/management expertise to ensure the scheme developed successfully

– Provide open book accounting and a long term profit share to SCC

and committed SCC to:– Take heat wherever practical for SCC buildings

– Provide land for the Heat Station for a peppercorn

– Help Utilicom promote the scheme to other potential users

– Provide general support to Utilicom in developing the scheme - planning, highways etc…

– Treat Utilicom as a ‘statutory utility’ within the boundaries of the City

• Supplemented by regular, often daily, dialogue to ensure that the scheme develops to deliver the aims of both parties

• Currently saving organisations within the City over £0.25M per annum in energy costs and delivering 11,000 tons of Carbon Savings

• LA Councillor and Officer Champion are essential to making the scheme work – this has been one of the keys to the success of the Southampton scheme

Why Connect ?• Capital cost savings – connection charge up to 25% less than

conventional plant• Space savings – direct connections mean no plant space required –

very valuable in urban areas• Operating cost savings – at least 10% when compared to the

alternative cost of heating/cooling/electricity - £0.25M • Guaranteed savings – prices linked to basket of indices to ensure

savings maintained throughout life of the contract• Delivers on LA 21 and Kyoto carbon savings – 11,000 tons• Ensures full and genuine outsourcing of energy supplies = risk transfer

Page 31: The Southampton City District Energy Scheme  a partnership between

WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS

How are connections funded ?

• Connection charges from the consumer• Long term energy supply revenues – repaying bank or

private sector finance• Grant funding – Community Energy Fund and others…

Page 32: The Southampton City District Energy Scheme  a partnership between

WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS

Do Consumers Connect ?• Yes – because they understand the benefits, i.e. Barratt Homes a convert

to the scheme

• However, many developers wish to use cheap electric heating – high emissions and operating costs

• Also building services consultants acting for potential consumers often prefer own plant as this is traditional and returns fees

• SCC/Utilicom work in partnership to demonstrate benefits and encourage use of Whole Life Cycle costing

• SCC can also encourage via the planning process, Section 106’s and land sale agreements

Barratt’s Park View Development

Some of the Key Benefits:• Capital cost savings - Barratt’s publish savings as £300 per unit• Space savings• No flues or gas pipework – removes gas from dwellings• Unlimited supplies of hot water• Operational cost savings

The Residents Views:“The flat warms up quickly, it’s quick and cheap” , “the economy appealed to us” and “ we have

constant hot water with good water pressure in the shower”

The Survey:78% were aware that the flat had community heating when they purchased it and 60% stated that

it influenced their decision in a positive way !78% also replied that they would buy electricity from SGHC if available and 66% thought that lack

of choice in a supplier wasn’t a problem

The Future – to 2010

• Further large scale CHP - increase to 20 MW ?

• Heating and especially cooling mains continue to grow - energy sales doubled

• Electricity sales to local consumers

• Incorporation of other technologies – anaerobic digestion of the Cities Waste– fuel cells– biomass etc…- currently developing wood fired boilers/CHP schemes

Page 48: The Southampton City District Energy Scheme  a partnership between

WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS
