3
www.southwark.gov.uk Background Section 106 agreement tied to waste facility site. On-site renewable energy generation not feasible. Agreement asked for community renewable energy scheme instead.
4
www.southwark.gov.uk De-centralised Heat Generation Proposal Use SELCHP to distribute heat to local estates Projected emissions reduction of 7,716 tonnes of CO ².
5
www.southwark.gov.uk Financial incentives For Southwark: Cheaper than gas Low carbon Cost benefits to increase over time For Veolia (Waste PFI partners): Price received was greater than electricity Cover construction and maintenance costs
6
www.southwark.gov.uk How it works Steam drives a turbine to generate electricity Condensed back to water and returned to boiler We bleed off steam during this process It transfers its remaining energy into our network
7

8
www.southwark.gov.uk How it works 1,200 Southwark properties benefiting Scheme funded by Veolia Potential to supply commercial customers
