Following changes in electricity retailing implemented at the beginning of 2018 in ACT and as part of the installation of solar panels, a new Smart Meter is installed. The installation of the Smart Meter forces the ACT consumer on to a new electricity tariff regime. For my situation I had to work out which of the alternative tariff regimes was likely to be the most cost effective choice. I found the Wattever site to be of greatest assistance in doing this than the other electricity comparison web sites. With the passage of time, I will use the web site as means of working out how well actual outcomes follow the predictions.
