Pilot storage projects
The growing increase in electricity generation plants using non-programmable renewable sources (NPRSs), especially in the Southern regions of Italy and on the two biggest islands have had an increasingly tangible impact in recent years on the dispatching of electricity and in general on the safe operation of the National Electricity System. In order to optimise generation from renewable sources and at the same time ensure increased security management of the Electricity System, Terna has identified energy storage as one of the possible solutions to the problem, planning the installation of new storage technologies connected to the National Electricity Transmission Grid (NTG). The innovative nature of using such systems on the NTG has led to Terna embarking on a first experimental phase for the realisation of two pilot projects, needed to test and validate the use of electro-chemical storage at the “utility-scale” level. The results of the experiment conducted by Terna will in fact make it possible to identify the potential and margins for improvement in battery storage, encouraging the development of innovative systems and solutions aimed at integrating new grid functions and optimising those which already exist.
