Household customers' assessment to capacity based distribution grid tariff

Abstract

This paper presents the status of regulation related to distribution grid tariffs in Norway, and household customers’ assessment of having such a tariff scheme. The paper is presenting results from a Norwegian pilot where two alternative tariff models where tested among household customers for 1 year. The tariff models are a capacity-based tariff with a subscribed power level and a time of use energy tariff with a daily peak price period in the afternoon (16:00-18:00). The results from the pilot are based on analysing hourly smart meter data and three customer surveys. The pilot shows that in general household customers have little focus on their electricity consumption, and especially related to peak load. Some minor changes in consumption can be observed, mainly consumption shifted in advance of peak price hours. The customers expect a cost benefit from changing their consumption (50% want to save 100-199.9 Euros/year).
