Residential battery storage systems (R-BESS) are gaining popularity in Europe. The amount of installed storage capacity rose by 2,3 GWh in 2021 to 5,4 GWh. New data shows that the installed capacity could almost double to 9,3 GWh by the end of 2022 and exceed 32 GWh in 2026.
These are the findings of new report from SolarPower Europe.
The dramatic growth in residential battery energy storage systems is driven by R-BESS’s synergy with residential solar PV installations in Europe, which have grown significantly in recent years. The average attachment rate between BESS and PV is said to have grown from 23% in 2020 to 27% in 2021.
Other factors include the dramatic rise in Europe’s energy tariffs, the need to become less dependent on imported energy, the rapid transition to electric vehicles, and the desire to decarbonise the electricity sector.
The report, which can be found here, analyses the largest four European markets, Germany, Italy, Austria, and the United Kingdom. The study reveals, however, that by 2026, Poland and Sweden could hold positions three and four.
