Grid tariff designs coping with the challenges of electrification and their socio-economic impacts (2210.03514v3)

Abstract: This paper investigates volumetric grid tariff designs under consideration of different pricing mechanisms and resulting cost allocation across socio-techno-economic consumer categories. In a case study of 1.56 million Danish households divided into 90 socio-techno-economic categories, we compare three alternative grid tariffs and investigate their impact on annual electricity bills. The results of our design consisting of a time-dependent threshold penalizing individual peak consumption and a system peak tariff show (a) a range of different allocations that distribute the burden of additional grid costs across both technologies and (b) strong positive outcomes, including reduced expenses for lower-income groups and smaller households.
