CHP, district heating and the role of decentralised energy in buildings

1. CHP, district heating andthe role of decentralised energy in buildings Jonathan Graham Policy Manager 8 October 2014

2. About The Chpa

3. Putting the energy user at the centre

4. CHPA Mission statement • Our vision is for an energy system that is dictated by the consumers' needs rather than one that dictates to them, creating a more local, efficient and less costly energy system • Areas of focus: • Combined heat and power • Sustainable energy services • District heating and cooling

5. A few of the CHPA members…

6. Current and Future UK energy System

7. UK Final energy use Power Oil derived fuels Gas

9. On-site generation helps manage costs

10. The need for smart systems Now Future? +5-9kW +3-6kW

15. the role of CHP and district heating

16. Opportunity of energy inefficiency Energy Flows in the Global Electricity System 2/3 of the fuel “we” use to produce power is wasted -- CHP can more than double this efficiency Source: IEA, CHP: Evaluating the Benefits of Greater Global Investment (2008).

17. Why is CHP more efficient?

18. CHP and security of supply

19. CHP provides lower costs and CO2Costs saved CO2 saved £31,000 539T CO2 185kW CHP £200,000 1,200T CO2 1MW CHP £300,000 3,500T CO2 4.7MW CHP

20. CHP in the UK • 1,900 CHP schemes in UK, with 1,500 in commercial and services sector • At least £200m new investment last year • 6.4% of electricity generation • 70% is natural gas

21. Fast-growing <2MW CHP sector

22. Wholesale vs retail electricity price

23. Gas CHP incentives Genuine value • CPS relief for on-site power (April 2015) • CCL relief for on-site power and all fuel • Enhanced Capital Allowances • Feed-in tariff for <2kW CHP Level playing field • CPS relief on fuel for heat generation • Business rates exemption • CHP heat treatment under EUETS • Embedded benefit

24. What is district heating?

25. District heating is technology neutral

26. Heat as part of an integrated energy system

27. District heating market Potentials from Pöyry/AECOM for DECC (2009) • ~50,000 dwellings on modern DH schemes • New build and retrofit planned projects will deliver a further 50-60,000 dwellings Modern DH schemes • 3 to 8 million dwellings • 15-26M m2 non-domestic floor space • Requires ‘de-risked’ cost of capital (3.5% SDR) and comprehensive application of carbon price Block heating refurbishment • 377,000 dwellings in England on ‘district heating systems’ ≡ 2% of dwellings • Includes both large and building-level schemes Campus Schemes Universities • Completed: 32 • Planned: 17 Hospitals • Completed: 64 • Planned: 20+? CHPA Survey: Modern DH Schemes • 108 completed schemes: >50,000 dwellings & ~900,000m2 commercial • >50 schemes planned: ~50,000 dwellings and 350,000m2 commercial

28. The growth of UK district heating Established with growth potential • Olympic Park and Stratford City (Cofely) • Barbican Arts Centre (Eon) • Guildhall, Bastion House and London Central Markets (Eon) • PDHU Emerging • Leicester City Council (Cofely DE) • Newport City Homes Limited • Manchester – Media City (Cofely) • Newcastle - Riverside Dean (Vital) • Stoke (tbc) • Association of Greater Manchester Authorities • Birmingham (Cofely) • Nottingham (Enviroenergy) • Shetland Heat, Energy and Power • Southampton City Council (Cofely) • Woking (Thameswey) • Sheffield (Veolia & Eon) • Milton Keynes (Thameswey) • Aberdeen (Aberdeen Heat & Power) London • Bloomsbury Heat & Power (Cofely) • Whitehall (GPS/Cofely) • Dalston Sq (Eon) • Greenwich Millennium Village (Eon) • Bunhill (Islington BC)

29. Local Authority-led development • Energy master planning • Planning requirements • Public buildings and social housing • Brokering, procuring, operating, owning heat networks • ECO delivery

30. Industry Initiatives

31. Independent Heat Customer Protection scheme • Consultation now concluded • Voluntary scheme aims to launch by December 2014 • Will set minimum standards for heat suppliers and customers • Customer service and reporting a fault or emergency • Joining and leaving procedures • Heat bill, heat charge calculations and heat charge comparator • Paying the heat bill and payment difficulties • Disconnection and re-connection process • Complaint handling and independent adjudication • Privacy policy and data protection

32. Heat Network Code of Practice • CIBSE and CHPA developing minimum technical standards for heat networks • Proposals currently out for consultation • Addressing issues related to the often too fragmented stages of delivery of a network

33. New small-scale CHP guidelines • CHP only provides benefits when it is installed and operated properly • Reputation risk to all parts of supply chain • Read and use CIBSE’s AM-12 Guidance • Energy audit to see if CHP right solution • Use reputable CHP supplier, with long-term O&M contract • Design properly to use CHP’s efficiency, low temperatures • Create a handover strategy with building users
