Abstract

This paper analyses the impact of substantial changes in energy production driven by self-supply associated with photovoltaic (PV) adoption, regarding the tariff rates payed by adopters and non-adopters and the revenues yielded by regulated tariffs. Three different regulatory design options are analysed with a model developed to estimate the evolution of self-supply deployment as a function of PV module price by: (i) the current Portuguese tariff structure and parameters; (ii) introducing a new network usage component for rate-payer energy suppliers, and (iii) evolving towards higher allowed revenues recovered through fixed tariff charges, compensating the decreased revenue associated with the volumetric tariff charge. The results of the analysis suggest that gradual transitions toward higher fixed Network Access charges do not dissuade PV deployment.
