  2. Background Scottish and Southern Energy plc Supply: 8 million customers gas, electricity, telephone Distribution: electricity and gas Generation: 2nd largest generation business in UK Largest generator of renewable energy

  3. Background Scottish and Southern Energy plc • Range of green products for customers including RSPB Energy • Energy efficiency measures saving customers 7.1GWh • 220,000 homes insulated with grants from SSE • 560,000 low energy lamps subsidised • Energy Efficiency advice line 0845 777 6633

  4. Background Government Policy “..put the UK on a path to cut CO2 emissions by at least 60% by 2050” EU Members have signed up for a 20% cut by 2020 (on 1990 levels) Energy conservation plays an important role • Energy Efficiency Commitment & Carbon Emission Reduction Target • European Directive 2006/32/EC More understanding is required of behavioural impacts • Advice and billing information • Tariffs • Metering

  5. Trial Overview Programme Scope 1 Information • Additional information on bills including graphs • Energy efficiency information • Monthly energy usage statements • Metering data provided over the web Price Incentives • A Time of Use Tariff which will offer price incentives to shift energy usage away from peak periods • An Incentive to reduce energy consumption

  6. Trial Overview Programme Scope 2 Metering • Smart Metering - with and without Customer Display Units • Remote reading from gas meters via the electric meter • Current Cost customer feedback devices • Token free ‘Pay as You Go’ for electricity prepayment customers • A range of remote meter communication systems

  7. Trial Overview Involved Parties Government Agencies BERR - project sponsors Ofgem - project administrator External Advisers Centre for Sustainable Energy - Ofgem Advisers SSC at Reading University - SSE Statistical Advisers CARBs Team at Reading University IBM – SSE Project Management Questionnaires (Face to Face) Natcen Meter and Display Manufacturers / Comms providers Ampy Horstmann / Technolog GE Energy / Nuri Telecom Current Cost Vodafone Orange Metering Data Management and Web Hosting Accenture Pay As You Go Ampy / Logica / Paypoint

  9. energy made better Surveys, Sample Groups & Experimental Design

  10. SCALE OF THE PROJECT • Total number of customers involved in the project = 28,000 • The project is split between 79 trial groups • An energy advice leaflet and three versions of additional energy advice • tariff variations available for over 4,000 customers • 400 in depth face to face surveys (before intervention and after one year) • Over 4,000 self-completion surveys (before intervention and after one year) • Control groups comprise 5,500 customers • approximately 8,000 to get smart meter installation • approximately 5,000 to receive real time “Current Cost” display • 1,430 in community trials

  11. CUSTOMER GROUPS • Sub-divisions within each intervention • High, Medium & Low Usage • Mosaic Classifications (11 Groups) • Payment Methods (Direct Debit, Cash/Cheque, Pay-as-you-go) • Fuel type (Electricity only or Electricity & Gas) • Different levels of trial awareness & commitment

  23. Tariff Incentives in General • Customer response to more sophisticated price messages are a key economic benefit. • International experience in customer trials is encouraging. • Technology allows very complex tariff structures but customers require simplicity. • Time of use tariffs should shift demand patterns reducing costs (particularly network costs). • Time of use tariffs may also help reduce the overall level of demand. • A separate efficiency incentive to reduce overall demand will also be tested.

  24. Tariff Incentives in the SSE Pilot • Alternative tariff is designed to be revenue neutral for typical usage pattern. • Customer will get benefit of savings but will not be required to pay more on alternative bill. • Weekday and Weekend rates will vary. • Charges will be set at a higher rate in “Winter” (Nov, Dec, Jan & Feb). • Charges will be highest in the hours around tea time and lowest at night • A sample of customers will be able to claim a refund for a reduction in consumption. • The impact of the different types of tariff intervention will be decomposed.
