ACCUMULO 2015 - Materiali e tecnologie per accumulo energia per sistema elettrico

Some of the case studies described in a recent "white paper" RSE – ANIE on electrical storage systems are presented.

Some of the case studies described in a recent "white paper" RSE – ANIE on electrical storage systems are presented. In particular, the focus is on using SdA in fossil or renewable power plants source and at end users with small photovoltaic systems. On the basis of current prices, only in certain situations an acceptable return on investment can be achieved: the use on a coal-fired plant USC, with primary reserve function, and in the case of a small island, not connected to the national network, assuming new installations of wind farms and photovoltaic covering most of the electricity needs.

It is concluded that the SdA based on batteries are a very versatile and modular solution in order to ensure the necessary flexibility to the electric system and/or to maximize local exploitation of renewable energy. However it is expected that an extensive application of SdA will be possible not immediately, but in a few years, as a result of a sharp reduction in battery costs, decrease to a large extent predicted by many observers.
