Jim Cardwell Low carbon networks fund conference Cardiff 26 October 2012
How may network technology and customer-side participation enable connection of low-carbon technologies at least cost? • Learning Outcome 1 (LO1) - Monitoring:What are current, emerging and possible future customer (load and generation) characteristics? • Learning Outcome 2 (LO2) – Customer flexibility: To what extent are customers flexible in their load and generation, and what is the cost of this flexibility? • Learning Outcome 3 (LO3) – Network flexibility: To what extent is the network flexible and what is the cost of this flexibility? • Learning Outcome 4 (LO4) – Optimum solutions: What are the optimum solutions to resolve network constraints driven by the transition to a low-carbon economy? • Learning Outcome 5 (LO5) – Effective delivery: What are the most effective means to deliver optimal solutions between customer, supplier and distributor?
Learning delivered is highly replicable across GB • Heat pump cluster • Focussed integrated network technology on rural and urban network: • Enhanced automatic voltage control • Real-time thermal rating • Electrical energy storage National smart meter data offers baseline electricity profiles • Analysis of new loads and generation • Active customer participation to minimise electricity costs through flexibility • PV generation cluster
Project on track to deliver the learning with key milestones achieved Customer trials • Over 13k customers already participating in monitoring and over 1k for active participation (majority on static time of use tariff) • Completed analysis of data for ca. 5k smart meters and ca. 150 in-depth social interviews Network technology • Installation well advanced, initial results from 20 validated models and operation of real-time thermal rating – remaining installation and commissioning by end 2012 • Control system integrating the network technology and linking to customer participation due for completion in Q1 2013 – factory acceptance testing this week Outputs • Foundation work completed for engineering policies and planning/design tool • Load and generation profiles published by end 2012 with more by April 2013 • Majority of outputs in 2013 - updated learning for heat pumps and electric vehicles in 2014
Customer enrolment has produced interesting insights… • High appetite for involvement from British Gas domestic customers - with ca. 10% take-up rates • Motive to participateis cutting bills - rather than saving the planet • Domestic time of use tariff particularly attractive - with ca. 700 customers taking part; restricted hours and direct control tariffs are a tougher sell • Electrically-heated water not suitable for further demand response - customers already on cheap night-rate tariffs or hot water tanks replaced by combiboilers • SME time of use tariff also attractive- but restricted hours and direct control tariffs are proving to be a tough sell • I&C demand side responseproved effective - 75% success rate; to be extended this winter and integrated in to the trial’s control system 70+ customer engagement documents I&C demand side response with commercial aggregators
… and the Durham University social learning is coming thick and fast • Domestic transitions characterise about a third of those interviewed – include household change, compaction and multiple living arrangements • Active energy management is present in many households - often based on ‘know how’ and domestic calculations rather than formal knowledge • Shadows of technologies past shape people’s energy practices today - new technologies are used with a physical or psychological ‘memory’ of the old systems • Energy load curve is driven by habitual routines and daily rhythms – children have particularly fixed routines and mealtimes restrict flexibility • Energy peaks relate to coming into/leaving households – e.g. showers, putting the kettle on, meals SME diversity Domestic energy behaviours
