In recent years, the UK energy storage market has entered a period of rapid growth. Since 2020, battery energy storage system (BESS) capacity in the UK has increased by over 500%, rising from approximately 1.1 GW to nearly 7 GW. In the first half of 2025, newly commissioned projects increased by 78% year-on-year, and the total grid-connected capacity is expected to exceed 8 GW by the end of the year.
The UK residential market is predominantly single-phase, with highly variable sunlight, frequent rainy weather, and diverse, fluctuating household loads. Energy storage systems must ensure round-the-clock power supply while supporting grid stability, peak-shaving, and maximized self-consumption. Swatten’s lightweight, modular, low-startup-voltage single-phase products are naturally suited for the UK market, providing households with stable, efficient, and flexible energy storage solutions.
Over the three days of the event, the Swatten booth was constantly busy:
Product demonstration area attracted numerous visitors, with single-phase residential storage systems and All‑in‑One units taking center stage, featuring hands-on experiences and interactive sessions.
Our technical team provided detailed explanations of single-phase systems’ low-light startup capability, lightweight installation, grid compatibility, and remote monitoring functionality.
Several channel partners, installers, and design firms expressed interest in collaboration, intending to further test our products and assess UK project feasibility.
Booth social interactions were lively, with customer photos and instant feedback providing Swatten with valuable market insights.
We sincerely thank every customer and partner who visited our booth—your support and attention have helped Swatten take a solid step forward in the UK market.
