I think where it gets complicated … is
if you then wanted to sell heat onto a
municipal network… The university is
never going to want to put itself in a
position where we need to shut off
heat to our biomedical research
facility because legally we’re obliged
to heat social housing up the road. ….
Some intermediary, [the] City Council,
needs to sit in the middle. But …
they’re not really in the business of
being that intermediary.

Danish and Swedishdevelopment • Post war experiments exploiting heavy / light oil price difference • Oil crisis led to national policies which placed responsibilities on local government • Embedded in wider systems of municipal service provision (including electricity) • Swedish house building programme • Danish power to compel connection • Heat networks regulated • Learning networks and technology development
- 10. Local Authorities • Havestrategic, long term view of area plus social responsibilities • Democratic oversight mitigates subscribers’ perceptions of monopoly risk • Planning policy can encourage connection and shape heat supply/demand patterns • Control large heat demand on own estate • Accept low (social) rates of return, but financially constrained • Cross-subsidy? • DH cuts across traditional departmental divisions
- 11. District heating inthe UK • Relative fragmentation of local government – Transfer of functions to other organisations – (Legacy of) central control • Shift from local government provision to enabling • No “problem owner” at present • Voluntaristic development model: political commitment and extensive negotiation of relationships • Diverse business models and economic evaluations
- 12. Where have weseen development? • Tendency towards single organisation projects • Sustainable City initiatives build local relationships even if project development appears slow • Scottish Community Energy Network secured 60% of CEP – Built local capacity and confidence • Aberdeen Heat and Power – exploration of commercial supply £0 £200,000 £400,000 £600,000 £800,000 £1,000,000 £1,200,000 2002-2003 2003-2004 2004-2005 Community energy programme Average Scottish Grant Average non Scottish grant

- 15. Conclusions • Diversity andflexibility in how heat networks are configured – Socially shaped – Greater impact of larger integrated systems • Governance arrangements in UK differ from European DH countries’ • Diversity in development models but most small scale with uncertain prospects for growth
