On 2 July the European Energy Storage Association (EASE) and analysts Delta-ee (Delta Energy and Environment) published EMMES 2.0, its guide for the European Energy Storage market published every 6 months.
The latest edition shows that the electrical energy storage capacity annually installed in Europe grew by 49% to 589 MWh between 2016 and 2017, which represents a steady growth rate since 2015. In 2018 it is expected to grow at a similar rate (45%) with the level of new installations accelerating.

The total installed base in Europe (excluding pumped hydro) reached 1.6 GWh at end of 2017.

Germany and UK remain the most important markets for grid scale projects. Italy is emerging as a rapidly growing market for residential electrical energy storage but Germany remains a clear leader.

Valts Grintals, senior analyst at Delta-ee, said “While market growth was strong in 2017, actually a number of important grid scale projects were delayed from 2017 into 2018.  But this was compensated by unexpectedly strong growth in the residential sector – meaning that the overall European growth rate was maintained. Over the first half of 2018, many of the delayed projects have gone live and we expect many new grid scale projects to be commissioned over the second half of the year. Additionally, behind-the-meter batteries in the C&I sector will emerge as an important market as key players are overcoming initial barriers for this market. Overall the outlook is very positive.”
Patrick Clerens, secretary general of the European Association for Storage of Energy said “EMMES 2.0 also offers insight into one of the hot topics in the storage sector: new business models for residential energy storage in Europe.”
