A capability assessment of over 100 home energy products was carried out and a database created.
Barriers to their integration were analysed. Key barriers identified were: Lack of engagement of customers in heating and home energy use; Inability of consumers to use heating controls; High initial costs for smart control devices; Barriers to half hourly settlement, needed for some DSR services, and availability of smart (e.g. time of use) tariffs.
Evaluation of costs and benefits lead to the following key findings:
- The plausible ways the consumer may interact with the original and ‘smart’ heating controls lead to very different outcomes in the change in fuel bill.
- DSR activities to reduce peak demand and provide frequency response could lead to significant value for the household, particularly in households with electric heating.
- Smart lighting and appliances offer a relatively poor economic benefit, but uptake is likely to be driven to a greater extent by improved user experience and convenience.
- The economic case for smart management of micro-generation with electrical or thermal storage is marginal, but could become attractive under falling battery prices or large peak/off-peak electricity price differentials.
