Is the clean energy transition making fixed-rate electricity tariffs regressive?
Wholesale electricity prices can rapidly change in real-time, yet households usually face fixed-price electricity tariffs. In markets with large amounts of solar electricity generation, households that predominantly import energy in the daytime when wholesale prices are low implicitly cross-subsidize households with energy use that is more weighted to the higher-priced evening. We map substation data on electricity use to demographic data, to identify the household characteristics associated with this cross-subsidization in a high-solar setting. We find that households in areas with low house prices and high levels of renters are the net funders of this implicit subsidy. These households currently have the lowest average energy cost for retailers to service, and could be the greatest immediate beneficiaries if real-time retail tariffs are made available, before accounting for price-responsiveness. Finally, we present evidence that cross-subsidy magnitudes have grown significantly in recent years, coincident with rapid solar generator penetration.
期刊介绍:
The Journal of Environmental Economics and Management publishes theoretical and empirical papers devoted to specific natural resources and environmental issues. For consideration, papers should (1) contain a substantial element embodying the linkage between economic systems and environmental and natural resources systems or (2) be of substantial importance in understanding the management and/or social control of the economy in its relations with the natural environment. Although the general orientation of the journal is toward economics, interdisciplinary papers by researchers in other fields of interest to resource and environmental economists will be welcomed.
