1. What is CHP and District 1. What is CHP and District HeatingHeating
WORKING IN PARTNERSHIP TO DELIVER SUSTAINABLE ENERGY SOLUTIONS
Combined Heat & Power (CHP) - recovery of heat produced when generating electricity (usually wasted)
What is CHP?
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?
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

The Partnership• Utilicom and SCC meet quarterly to plan new developments
• SCC representatives led by Executive Director (Mike Smith), building design, planning, environment, regeneration, highways etc..
• 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

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
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…
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
