Executive Summary

This month’s Update From The Field proves that the US market remains the most dynamic one for energy storage. Indeed, be it for interesting regulatory changes, number of projects or event justifying a very long and detailed focus of the month, the USA are present in all parts of this month’s report. With California of course, considering that an additional 80 MW has been procured there, and most importantly, that almost half a billion dollars have been made available to fund Behind-The-Meter energy storage over the next three years.

In Europe, self-consumption goes a step further with new feed in tariffs allowing to self-consume electricity and inject the surplus into the grid in France and a draft law published in Germany to encourage the offtake of residential storage systems for home tenants.

This May, the Self Generation Incentive Program is re-opening in California and is specially oriented to support energy storage systems behind the meter. The understanding of this incentive and the deriving business models are analyzed in the focus of the month.
