Title: Energy storage and photovoltaic distributed generation — Evaluation of impacts on the remuneration of prosumers
Abstract: Photovoltaic distributed generation (DG) in Brazil has recently gained significant momentum towards established long term goals. Although the market is still in the initial stages, the economic attractiveness of the net-metering model may be impacted by regulatory changes, similarly to what has happened in advanced markets in Europe and USA, where the remuneration of the exported energy has decreased over time. In this context, this paper analyzes potential developments in DG considering the upcoming offering of the time of use (TOU) White Tariff (WT) to residential customers, the advent of energy storage and the hypothetical inclusion of feed-in tariffs as an alternative to net-metering. The work employed energy demand and generation profiles built from actual customer typology and solar irradiation data to quantify the excess energy to be stored in batteries for use at peak demand periods, and evaluate the benefits of storage in conjunction with flat and hourly tariffs. Overall, the results indicated that feed-in and WT seem to be a good combination for prosumers. On the other hand, feed-in did not sound very attractive for usage with residential flat tariffs. The analysis also showed that under net-metering, the current tariff structure does not promote the adoption of energy storage, an aspect that may require some attention in future discussions regarding the evolution of DG in the Brazilian market.
