dc.description.abstract© 2024 Elsevier LtdThere is a need for a methodology that allows the prosumer to implement a policy of choosing different compensation mechanisms. Thus, we propose the economic equivalence between net metering rolling credit (NM-RC) and net billing buyback (NB-BB) by defining a breakeven price (BP) for NB-BB that equals the Net Present Value (NPV) of these two options and using Discounted Payback Time (DPBT) as a tiebreaker metric. The Brazilian scenario was used for validation. When using the retail price, the NPV values for the NM-RC mechanism were lower in all scenarios (mean NPV of US$ 3958.66 in NM-RC against US$ 4372.17 in NB-BB). It is possible to observe that the BP that equalizes the two mechanisms is generally lower than the tariff charged by the utility (mean BP is US$ 0.1111 while mean tariff is US$ 0.1838), which reveals that offering this choice option does not burden the system. The NM-RC was selected in four cities, and the NB-BB was chosen in three cities. This policy could encourage potential prosumers, who often feel reluctant to invest in PV-DG owing to the long payback period. Thus, the political schemes complementing the compensation mechanism are relevant, especially for continental-sized countries with many utilities.
