Southwark’s New District Heating Network

Southwark’s Carbon Reduction Strategy Borough-wide CO 2 emissions down by 80% by 2050 Council housing stock emissions down by 15% by 2022 Fuel poverty reduced

Background Section 106 agreement tied to waste facility site. On-site renewable energy generation not feasible. Agreement asked for community renewable energy scheme instead.

De-centralised Heat Generation Proposal Use SELCHP to distribute heat to local estates Projected emissions reduction of 7,716 tonnes of CO ².

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

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

: Locations of estates benefiting : Location of SELCHP

How it works 1,200 Southwark properties benefiting Scheme funded by Veolia Potential to supply commercial customers

Technical Details 5km of pipe laid beneath roads Minimal heat loss Leak detection system

Technical Details SELCHP pumps drive 110 °C water around the network Heat exchangers at each boiler house
