Households are happy to join together and provide power flexibility for climate action


Published on

Residential and small commercial electricity consumers will provide most of the flexibility needed in the power system to achieve the energy transition at lower cost. This flexibility will allow the electricity grid to take on more renewables and need less grid reinforcements. Consumers are happy to participate (>75% opt-in rate) via an aggregator and be rewarded with energy savings reducing their electricity. Because it reduces the overall costs of running the energy system, it means that all consumers benefit from lower energy prices. The business case is now proven as more and more countries worldwide ensure demand side response can participate in wholesale markets as an alternative to generation and the EU has provided support through its recent Clean Energy Package. Pierre Bivas from Voltalis will share his experience of operating flexibility from more than 100,000 households in France, and now installing another 150,000, backed by the European Investment Bank, while also developing in other countries with local partners.

Complementary to (Smart)Meters More flexibility than via price signals Ø Voltalis X-IoETM is operated « beyond the meter », and doesn’t compete with DSO (smart) meters, but provides complementary services, both for end-users and grid operators SMART METERS Metering Overall metering, only Sub-metering of each appliance connected (each heater, heat pump, water boiler, aircon…) Communication Differed, once a day Real-time Frequent (every few minutes/seconds) Action on home appliances Not directly (but can send price signals to other devices - such as Voltalis box - that will act on appliances) Real-time modification of the consumption (or settings) of each appliance Aggregation of micro-shedding No Yes, in real time, with specific algorithms Example of Voltalis practical applications: Reshaping of water boilers load curve 22:30 22:50 23:10 23:30 23:50 0:10 0:30 0:50 1:10 1:30 1:50 2:10 2:30 2:50 3:10 3:30 3:50 4:10 4:30 4:50 5:10 5:30 5:50 water boilers : load carving 21/3 22/3 Voltalis operation on 3,000 water boilers Based on Machine Learning, water boiler consumption can be spread within low-tariff hours in a more efficient way than through Price Signals Reference with water boilers based on price signal: all start at the same time, creating an artificial peak Example of a dynamic reshaping managed by Voltalis that divides the peak by 2 1 1 2 2 The load curve can also be managed according to external constraints, such as instant renewable production, national balancing needs, etc. 14
