Scottish and Southern Electricity Networks (SSEN) Distribution has deferred £44 million of reinforcement work by using flexibility services instead. In total, SSEN has procured 700MW of flexibility during the past year. The company’s first annual DSO submission reveals that this has allowed it to avoid £44 million in reinforcement costs for RIIO ED2, some £12 million more than its target for the whole of the regulatory period to 2028.
