Domestic time-of-use electricity tariffs — what’s changed since 1978?

Staithes, Yorkshire — during the evening peak

Currently, most time-of-use tariffs use Economy 7 meters (est. 1978)

  1. Measurement of electricity usage over short, within-day time periods
  2. Flexible demand that can consume electricity off-peak (e.g. storage heaters)
  3. Market and billing systems to support financial risk management and settlement (i.e. buyers and sellers are correctly exposed)

Smart meters and EVs to the rescue?

Smart time-of-use tariffs and technologies are slowly entering the market

  • Tide by Green Energy UK (released Jan 2017, discontinued)
  • Agile Octopus by Octopus Energy (released Feb 2018)
  • Economy 24 by Social Energy (released Jun 2019)

In the next few years, expect more ‘EV tariffs’ and uptake of flexible demand-side technology

Over the coming decades, time-of-use can help us reach net-zero
