1. Market Overview
1.1 Market Definition
The global residential ESS (Energy Storage System) industry is a key downstream segment of the global energy storage solution industry, referring to the sector that develops, manufactures, sells and services electrochemical energy storage systems and supporting solutions exclusively for household/residential end-users.
1.2 Market Size and Growth
From 2019 to 2024, the global newly installed residential capacity of energy storage grew from 1.7 GWh to 19.4 GWh, with a CAGR of 62.7%. It is expected to reach 76.0 GWh in 2030, with a CAGR of 25.6%. Europe is the leading market that contributes to the global residential ESS industry; the newly installed residential ESS capacity in 2024 was 13.9 GWh, accounting for 71.6% of the global market. The current residential energy storage market in the UK is relatively small, with a newly installed ESS capacity of only 0.6 GWh in 2024. However, it is expected to grow rapidly at a CAGR of 42.4%, reaching a scale of 5.0 GWh by 2030.
Note: Non-electrochemical storage technologies, such as pumped hydro, flywheel, and compressed air energy storage are not included.
Europe denotes the geographic region rather than the political entity of the European Union.
