The Greek pilot explores how residential consumers can contribute to a reduction of market imbalances by shifting the electricity consumption of their water heaters. The iFLEX Assistant communicates the requests for action to the household and handles its response according to set preferences.
The capability to shift electricity use is in the Greek case offered as a service by a Demand Response Intentional change of normal consumption patterns by energy consumers in response to external price signals (implicit DR) or incentives to reduce or increase consumption (explicit DR). Both operations can be automated. Aggregator Market participant acting between providers and users of flexibility. The Aggregator bundles flexibility resources (consumption, generation, storage) into a flexibility volume and offers the capability to activate it. to a Renewable Energy Source (RES) Aggregator to reduce potential imbalances in the balancing market. In Greece, the former provides balancing services based on demand-side consumption, generation and storage and the latter based on generation from renewable power plants.
The demand-side aggregation role is initially fulfilled by the Electricity Retailer who sends a request to the household for participating in a future Demand Response (DR) event, which for the pilot involves shifting the consumption of the water heater. In return, the household is rewarded.
The household can provide a positive or negative response. If agreeing to participate in the event, the iFLEX Assistant suggests one or more options for rescheduling the water heater based on modelled preferences which need to be accepted by the user for successful participation. In a minimum supervision scenario, the user can choose auto-mode, leaving it up to iFLEX Assistant to decide on participation and rescheduling of the water heater.
