The programmeÌýcommittedÌý£13.9ÌýmillionÌýto support the innovation, design, and demonstration of interoperable demand side response systems. These systems included energy smart appliances (ESAs) and Demand Side Response Service Providers (DSRSPs).ÌýÌý

Projects funded by the programme helped to:Ìý

• develop energy smart appliances and energy management systems for interoperable demand side responseÌýfollowingÌýPubliclyÌýAccessible StandardsÌý(PAS)Ìý1878 and 1879ÌýÌý
• provide valuable feedback on PAS 1878 and 1879 for their revision

Programme structureÌý

The programmeÌýconsisted of 3 streams of work andÌý2Ìýtesting delivery partners.ÌýSee details of the funded projects:ÌýInteroperable Demand Side Response Programme: projects Streams 1-3 and testing delivery partners.

• Stream 1: over £7.2ÌýmillionÌýofÌýfunding for projectsÌýtoÌýdesign and develop Demand Side Response (DSR) and energy management systemsÌýin accordance withÌýthe PAS 1878 and 1879 standards.ÌýCommunication between the ESA and DSRSPs were via public comms networks and home networks.Ìý

• Stream 2: over £2.3ÌýmillionÌýofÌýfunding for projects toÌýdesign and develop Demand Side Response (DSR) and energy management systemsÌýin accordance withÌýthe PAS 1878 and 1879 standards.ÌýIn contrast to Stream 1, communication between the ESAs and DSRSPs was via the GB smart metering system.ÌýÌý

• Stream 3: overÌý£80,000 ofÌýfunding for projectsÌýtoÌýundertakeÌýfeasibility assessment to understand the different functional and technical options available to create interoperable domestic energy management system.ÌýÌý

• Testing delivery partners: over £5.2ÌýmillionÌýof funding for the testing delivery partnersÌýtoÌýtest the projects developed by Stream 1 andÌýobserveÌýdemonstrations of the systems developedÌýbyÌýStreamÌý2.Ìý

  • Lot 1: Lot 1 performed laboratory-based testing on the systems to see how well they performed and how closely they conformed with PAS 1878 and 1879.ÌýÌý
  • Lot 2: Lot 2 performed demonstrations in a setting indicative of the real world, where multiple ESAs from different projects were all connected to a single DSRSP at the same time.Ìý

The results from the programme informed the development and revision of the PAS 1878 and 1879 standards.ÌýÌý

The programme formed part of the Department for Energy Security and Net Zero’s wider innovation portfolio, supporting the transition to net zero byÌýdeveloping interoperable systems capable of delivering demand side response.Ìý

BackgroundÌý

°Õ³ó±ð 2021 Smart Systems and Flexibility Plan set out a suite of policies to enable flexibility from consumers, known as ‘demand side response’.ÌýConsumers will need access to ’energy smart’ appliances that make it easier to change their consumption patterns, alongside tariffs and services that incentivise this change.Ìý

Interoperability of energy smart appliances will enable consumers to access different propositions for demand side response, either earning revenue or reducing costs through providing value to the energy system. Increased uptake of demand side response will reduce the costs of decarbonisation, reducing bills for all consumers.Ìý

As part of this, the government committed to taking powers to set regulatory requirements for ‘energy smart’ appliances, guided by the core principles of interoperability, data privacy, cyber security, and grid stability.
