The Smart Secure Electricity Systems (SSES) programme is a government programme to establish technical frameworks, governance, and policies to securely unlock consumer-led flexibility (CLF) in the domestic-scale market, empower consumers to save on energy bills and enable the scaling of competitive and trusted CLF markets.
Elexon will deliver the Enduring Governance arrangements for the Smart Secure Electricity Systems Programme.

About the Enduring Governance role
Elexon will establish, administer and support two new, industry-led governance groups. These groups will initially be constituted as BSC Panel subcommittees, but their status will be reviewed and aligned to the final position of Ofgem’s Energy Code Reform.
Energy Code Reform will see Elexon become the licenced Code Manager for the BSC and will involve the transfer of many existing Panel subcommittee decisions and powers to Elexon as the Code Manager.
All costs will be treated as BSC Costs, accounted for separately from other activities.
