To ask Her Majesty's Government, further to the Written Answer by Lord Ashton of Hyde on 6 June (HL8104), what systems are in place across existing mobile networks to ensure that they continue to operate during a prolonged power outage.

DCMS works closely with industry to ensure that telecoms, as one of the UK’s critical sectors, is both secure and resilient. This includes work to ensure that security and resilience plans are updated and developed as technology changes and to reflect key risks and contingency planning. The industry-led Electronic Communications Resilience & Response Group, which DCMS supports and facilitates, is a cross-government and industry partnership that leads on resilience activity in the telecoms sector as a whole and considers a range of security and resilience issues including power loss.
