Home energy systems are getting smarter. Bidirectional EV chargers, solar panels, home batteries, heat pumps — the hardware is increasingly capable of responding to grid needs in real time. Yet for most households, this potential remains locked behind the meter. The missing link is not more hardware intelligence: it is the ability to translate local energy behaviour into standardized, transparent, market-ready flexibility that energy markets and grid operators can actually act on.
DCBel builds one of the most advanced residential home stations on the market — integrating a V1G/V2G-capable EV charger, home battery, and solar PV management into a single platform with its own digital layer for local energy optimization. DCBel needed to extend the value of that platform beyond the home: giving customers access to flexibility market revenues, while ensuring that local energy management priorities — self-consumption, comfort, battery health — were never compromised.
DCBel and Digital4Grids built an end-to-end flexibility monetization capability by combining two complementary digital layers. DCBel’s home intelligence handles everything facing the prosumer: self-consumption optimization, V2G charging management, comfort-aware scheduling, and real-time sub-metering through its edge platform.
Digital4Grids’ technical aggregation components sit above, facing the market: computing flexibility baselines, constructing standardized offers, orchestrating multi-program activations, and managing all interoperability with flexibility service providers, system operators, and market platforms through IEC 62746-4 and IEC 62325-compliant APIs. The solution is validated through the Eclipse Digital pilot, co-funded under the EU Digital Europe Programme, across 5 real homes and 10 digital twin simulations in France, with Voltalis as VPP aggregator and Enedis as DSO.
For residential customers, the combined solution unlocks an estimated €1,000+ in annual flexibility revenue from a 10 kW home station asset — roughly 25% of a typical annual energy bill through participation in ancillary services (FCR, aFRR, mFRR) and energy markets (day-ahead, balancing), without compromising local energy autonomy or comfort.
For grid operators and aggregators, the solution delivers observable, predictable, standards-compliant DER flexibility at scale with the metrological rigour and audit trail required for settlement and regulatory compliance.
For the market more broadly, the partnership demonstrates a replicable blueprint: any OEM with a capable home energy platform can connect to Digital4Grids’ technical aggregation layer and immediately access a portfolio of flexibility programs across European markets, without rebuilding the market-facing stack from scratch.
