The UK government's recent call for evidence on unlocking barriers to shared battery storage across the country is a crucial step towards addressing the solar disparity between houses and flats. This disparity, where houses are more likely to have solar panels than flats, is a significant issue that needs to be tackled to ensure a more equitable clean energy transition. The disparity is particularly evident when comparing the UK to countries like Australia, where community batteries are already being used at scale. Energy companies and experts, such as Jack Taylor from Allume Energy, emphasize the potential of shared solar and community batteries to address this imbalance. By integrating rooftop solar with shared battery systems, like Allume's SolShare 2, flats can benefit from increased energy savings and a more flexible electricity system. This is especially important given the recent geopolitical instability, which has increased the interest of UK adults in installing solar panels. The government's Future Homes Standard, which mandates solar panels and green heating systems in new homes, is a positive step, but it must be accompanied by initiatives to support existing flats and renters in accessing clean energy solutions. The successful implementation of shared-battery projects, such as the one in Lambeth Council's Elmore House, demonstrates the potential for community-based energy solutions to lower bills and support a more sustainable energy system. However, there are still regulatory and commercial barriers that need to be addressed to fully unlock the potential of shared battery storage. The call for evidence is a crucial first step in this process, and it is essential that the government listens to the views of those who will be most affected by these changes, including renters and people living in flats. By doing so, the UK can move towards a more flexible and equitable energy system, ensuring that the benefits of clean power are felt by all households, regardless of their housing type.
