ENECHANGE CEO’s Cambridge research on optimizing time-of-use rates using smart meter data published in peer-reviewed journal “Energy”
ENECHANGE Ltd. (Head Office: Chiyoda-ku, Tokyo; Representative Director & CEO: Yohei Kiguchi; Representative Director & COO: Ippei Arita) has published a paper titled “Predicting Winners and Losers under Time-Of-Use Tariffs Using Smart Meter Data”, which summarizes his doctoral research at the University of Cambridge, UK. The paper was published in Energy, a peer-reviewed academic journal that is considered to be one of the best in the energy field.
The research was conducted in collaboration with Dr. Melvyn Weeks of Cambridge University and researcher Riku Arakawa of SMAP Energy Limited., and was supported by Looop Corporation (Head office: Taito-ku, Tokyo; President: Soichiro Nakamura), which provides Looop Denki, for the acquisition of data on electricity usage and user attributes under time-of-use tariffs and the provision of the accumulated data for academic use.
Abstract of Research paper
Title: Predicting Winners and Losers under Time-Of-Use Tariffs Using Smart Meter Data
Time-of-use electricity tariffs may become more widespread as smart meters are installed across deregulated domestic electricity markets. Time-of-use tariffs and other methods of time-dependent pricing can be mutually beneficial, realising a cost reduction for both energy companies and customers if the customer responds to the price signalling. However, such tariffs are likely to create positive and negative financial outcomes for individuals due to customer engagement and potential peak shifting capacity. Identifying potential reducers or non-reducers beforehand can optimise a time-of-use programme design, in turn maximising the outcome of the programme. This paper provides a statistical model to identify the characteristics of so-called winners and losers — or households that would be better or worse off under a time-of-use tariff — using only ex ante information. The model’s accuracy reaches a reliable level using historical electricity load and basic household characteristics. This accuracy can be further improved if online activity data is available, providing justification for digital interaction and gamification in time-of-use programmes. This paper also publishes a new public dataset of 1423 households in Japan, including historical smart meter data, household characteristics and online activity variables during the time-of-use intervention period in 2017 and 2018.
