Electricity

What does the Electricity domain measure?

The Electricity domain is one of nine domains within the Smart Readiness Indicator (SRI). It assesses how intelligently a building manages its own electricity supply.

This includes local generation, for example with solar panels, storage in batteries, and shifting consumption to times when power is cheap or renewable. This domain is seen as central to energy flexibility in a building.

Which smart-ready services belong to this domain?

The domain contains seven services. Each service describes a specific function and has its own scale of functionality levels, from 0 (no function) to 4 (fully automated and predictive).

• E-2: reporting on local electricity generation, from current figures to predictive management.
• E-3: storage of locally generated electricity, for example in a battery, with control based on grid signals.
• E-4: optimization of self-consumption of locally generated electricity, from time-based scheduling to predictive management.
• E-5: control of the combined heat and power installation, a system that generates heat and electricity simultaneously.
• E-8: support for microgrid operating modes, where a building shares power with the neighbourhood or can operate independently.
• E-11: reporting on energy storage, including the charge status of batteries.
• E-12: reporting on electricity consumption, from building level to appliance level with personal recommendations.

Why does this domain count towards the SRI score?

Each smart-ready service contributes to the overall SRI score through impact criteria, such as energy efficiency and grid flexibility. A higher functionality level in this domain points to greater ability to align consumption and generation.

Buildings with battery storage, grid-responsive control or microgrid functions typically score higher than buildings without these systems.

For whom is this domain relevant?

This domain is particularly relevant for buildings with solar panels, battery storage or a combined heat and power installation. For utility buildings with an installation above 290 kW, the SRI is expected to become mandatory through a delegated act.
