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

… 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

data analysis
Data Analysis
  • 14,000 I&C customers, ½ hrly 2 years
  • 5,000 residential customers, ½ hrly 1 year
    • 9,000 target
  • 1,700 SME , ½ hrly 1 year
    • 2,250 target
  • Plus network monitoring LV, RTTR …
  • Test Cell 1 data alone is comparable to the size of the Irish Trials, we have 20 test cells
