A planned commercial and industrial (C&I) energy storage project in England could increase onsite solar consumption to the point that no power will be drawn from the grid on some days of the year.

Battery storage is of growing interest to commercial and industrial (C&I) entities in the UK, but the wider energy efficiency sector has seen Brexit and other policy woes send confidence to new lows.

Involvement from billionaire Peter Thiel in Stem’s Series C indicates a shared belief among investors that “distributed, intelligent storage is going to absolutely revolutionise the electric grid over the coming decades”, the company’s marketing director has said.
