Final Meeting of the Project “Energy efficiency policies: a worldwide panorama”
Under the guidance of the Energy Efficiency Policies & Technologies Knowledge Network 27-28 May 2013 WEC/CFE/ADEME
Case study on innovative smart billing for
household consumers
Christophe Dromacque
Background
• Households are often perceived as a very difficult target group for energy efficiency programs due to their diversity and the fact that they often see energy as a low interest and low involvement product
• However:..
Households account for about 30% of the EU’s final electricity consumption and between 20% and 39% in the markets reviewed as part of this report
Globally, residential consumption is expected to increase steadily in the foreseeable future
Energy prices keep increasing much faster than inflation in many parts of the world
• Need to be addressed if environmental targets are to be met and for affordability reasons VaasaETT 3

behaviors leading to reduction in energy consumption, bills and
increased customer satisfaction;

15 million homes receive similar reports designed by Opower in the US
and elsewhere (online or paper-based)
Awareness of energy consumption • 83% of customers remember receiving the reports • 73% read it thoroughly • 74% act upon it
Improvement in customer relationship • Level of overall customer satisfaction with utility is 6% for customers who receive the reports • customers exposed to this program are more likely to get involved in other utility offerings and programs

Awareness of energy consumption • 82% of participants made some change to the way they use electricity • 87% made changes to the way they use gas
Consumers satisfaction with usage statements • The electricity usage statements were rated as effective or very effective in helping to reduce usage by 79% of the participants •The electricity usage statements were rated as effective or very effective in helping to reduce usage by 54% of the participants
“Soft” benefits
Finding 2
• Smart bills can be a cost efficient way to save energy;
Opower-like programs such as the one reviewed in the Californian case study
costs an electric utility 7.48 USD per household per year or 2.5 cents per kWh
saved (1.6 and 6.4 ¢/kWh saved for other energy efficiency programs)
Finding 3
• Smart metering does not necessarily result in smart billing or any
other feedback programs without adequate regulation,
Sweden did not mandate smart meters but only monthly accurate billing. The goal was to address customer dissatisfaction with billing and switching errors. Thus, the legislation did not specify any minimum requirements for meters. Network companies responsible for implementing billing simply sought to comply to the regulation and improve their operations. The possibility to use smart meters to provide consumption feedback to households and as a building block for a smarter electricity grid was overlooked. The cost amounted to around €220 per customer, paid for by customer but no comprehensive feedback (or dynamic pricing) program that would allow them to benefit was launched by utilities. The smart meters would need to be upgraded to allow for such advanced programs.
Finding 4
• Feedback programs can increase the acceptance of dynamic tariffs
or smart meters rollouts;
In an attempt to shave peak demand, the Victorian Department of Environment and Primary Industries decided in 2007 to roll out smart meters and ToU tariffs to all customers by the end of 2013 but without IHDs as was planned at first. Following this decision, Victorian households and consumer associations started complaining about the inflated electricity bills to pay for the meters without being accompanied by any means to track and manage electricity consumption even though it was one of the main arguments to support the roll-out. In the face of the popular backlash that ensued, the Victorian government announced in March 2010 a moratorium on mandatory ToU tariffs (still in place) while the installation of smart meters across Victoria continues in accordance with legislative requirements. Without dynamic tariffs, the main objective to shave peak consumption will be negatively impacted.
Finding 5
• Although quality and insight are greatly improved by the data
granularity enabled by modern metering systems, effective smart
bills can also be implemented with traditional meter data;

Finding 6
• The most advanced and arguably the best cases of smart bills are to
be found in countries with both enhancing technology and
supporting regulation.
Enabling and supporting policies - California
• Smart metering minimum requirements with hourly
reading and third party access;
• Billing rules in effect mandate smart billing;
• Utility revenue decoupling.
VaasaETT 25
Enabling and supporting policies - Ireland
• Smart metering requirements (half hourly reading, third party
access)
• Energy usage statements and IHDs to be rolled out to all
consumers and IHD)

1. The specific design of the bills should be left to market forces to allow for innovation and creativity;
2. Some building blocks of smart billing have proven effective and should be made mandatory. These elements include: (i) normative energy use comparison, (ii) tips and advice as to how to reduce overall energy usage (iii) tips and advice as to how to benefit from dynamic tariffs if applicable), (iv) historical consumption data in order to track progress, (v) in case energy is subsidized real cost and real bill size should there be no State subsidy should be mentioned, (vi) indicate the different elements of the bill and who is responsible (retailer, DSO, State) and finally (vii) show pollutant emission associated with billed energy consumption;
3. We believe (in the same way the Energy Efficiency Directive) that accurate billing frequency should increase to possibly monthly;
4. Supporting regulation should ensure that feedback and education requirements be an integral part of any smart meter or dynamic pricing policy package to ensure that all consumers can benefit financially and otherwise.
What would 1.8% electricity consumption
reduction per year mean for the US alone?
VaasaETT 29
reducing residential electricity usage across the United States by 26,000
GWh;
reduce greenhouse gas emissions by 8.9 million metric tons of carbon
dioxide per year – equal to the emissions from three 500-MW coal-fired
power plants;
save households just over $3 billion dollars per year on their electric
bills.
