The UK Department of Energy Security and Net Zero (DESNZ) have launched a consultation on delivering a Smart and Secure Energy System (SSES).
The consultation is open until 21 June 2024.
It includes topics around:
- Energy Smart Appliances (ESA)
- Licencing Regime for DSRSPs (Demand Side Response Service Providers)
- Time of Use Tariffs
In the consultation document on ESAs:
We propose to bring into force Phase 1 requirements in 2026. Phase 1 requirements are
intended to ensure that devices with the greatest load potential (heat pumps, domestic battery
energy storage systems and electric vehicle chargers) meet minimum levels of security and
functionality.The security requirements include addressing cyber security risks through
proposing to implement the standard ETSI EN 303 645 as well as requirements to mitigate
potential risks to grid stability, such as a randomised delay function2. We deem that regulations
on electric vehicle chargers already meet these requirements, and so we focus on other ESAs.
We propose to bring into force Phase 2 requirements in 2028. This set of requirements will
build upon and subsume the Phase 1 requirements; they will rely on technical standards that
are still in development, such as the technical standard PAS 1878, which is currently
undergoing a revision supported by the Interoperability Demand Side Response innovation
competition.
We are proposing that once the second phase of ESA regulations are introduced, devices will

need to comply with approved interoperability and cyber security standards in order to be sold
in Great Britain. As set out in the document, in parallel to this consultation we intend to launch
a review of PAS1878 ahead of considering it as a route to compliance with this requirement.
We are also open to working with industry on the development of further, complementary
standards that could work alongside PAS1878 and provide alternate routes to compliance.
