Battery storage for renewable energy, such as solar PV or wind power, is critical for resilience and energy security. Take EV charging infrastructure as an example. By installing a solar array nearby, the renewable power generated can be fed into a battery system, which in turn feeds into the EV chargers. This means the site is less reliant on the grid. It increases resilience as power to charge the vehicles can be drawn from an alternative source, flattening peak grid demand. This reduces the UK’s reliance on imported power, which is typically purchased at such times.
By becoming more energy self-sufficient, the UK becomes less vulnerable to global events that may disrupt supply.
