The project will have 2 phases; the first will investigate and report on the commercial viability of the tariff, exploring current and future value streams to fund it. Whilst there is clear value to the generator we also want to explore the value for both supplier and DNO. Phase 2 is the domestic demand side response trial. With a tariff subsidised by the supplier, we will investigate the effects of the tariff on demand, exploring the extent and reliability of any increase. Four levels of intervention will be trialled, tariff only, tariff & feed-back, basic automated water heating and fully automated flexible load switching. The tariff will be managed and administered by Tempus however the customer engagement will be conducted by the local energy cooperative WREN.
We envisage that this type of connection could be of particular interest to community energy groups such as WREN who don’t have the movability of commercial developers but would have the links to change customer behavior.
No generator will be connected as part of the trial due to the inherent financial risk.
The project will address the following questions:
- Whether and how an offset connection agreement could be structured to be commercially viable for a generator?
- Whether and how an offset connection agreement could be structured and implemented to provide confidence to a DNO that the network will remain within operating limits?
- What mix of low tariff, behavioural signals and technology options would be most effective in shifting demand?
- What scale, longevity and reliability of demand side response would be achieved by the most effective method?
- Understanding of feasibility of an offset connection agreement for both DNO and developer (including legal arrangements)
- Understanding of the capacity, longevity and reliability of domestic demand side response
- Recruitment of over 200 participants in the trial, on time and on budget
- Retention of at least 80% of participants through to the end of the trial
- Learning gained in the project successfully disseminated.
