Turning homes into flexible grid resources
Nogara's Flexibility System enables DSOs, energy retailers and end users to monitor and control energy assets behind the smart meter over the existing electrical wiring.
One physical medium. Two coordinated PLC domains.
Outdoor PLC connects the utility network to the smart meter. Indoor PLC extends standards-based communication behind the meter, where the HC-PLC coordinates the home's flexible assets over the existing electrical wiring, with no new communication cabling and no additional wireless links.
Utility-side PLC: proven grid communication
The DSO, through the secondary substation and the data concentrator (DCU), already communicates bidirectionally with every smart meter over NB-PLC. This AMI architecture is proven at national scale, but its communication currently stops at the meter.
Home-side PLC: communication beyond the meter
Beyond the meter, the HC-PLC acts as the brain of the home, coordinating every asset over the same electrical wiring: EV chargers, heat pumps, PV inverters, batteries and controllable loads.
One coordinated communication architecture, from the DSO to every energy asset
The devices behind the system
From smart metering to coordinated flexibility
The meter bridges the two PLC domains
The smart meter connects the utility's Outdoor PLC with the home's Indoor PLC, extending standards-based communication past the metering point.
The HC-PLC coordinates the home
As the brain of the home, the HC-PLC monitors and controls each asset and returns its status, availability and command acknowledgements.
Flexible assets become visible and controllable
An authorised DSO, retailer or aggregator can request and coordinate the flexibility available behind the meter (EV, heat pump, PV, battery, loads), previously out of reach past the metering point.
One home. One visible node. One coordinated flexibility resource.
To the utility-side network, the home stays represented by only the smart meter. Behind it, the HC-PLC coordinates the available assets, from EV chargers and batteries to heat pumps and solar systems, and exposes their combined flexibility without adding new nodes to the external PRIME network.
This is the In-Home Device (IHD) architecture: more intelligence behind the meter, with no added complexity for the utility.
Built on utility-grade standards
Engineers turning utility standards into field products
Nogara Technologies is a Zaragoza-based company with deep roots in electronic engineering. Our team has delivered PLC communication, channel characterisation and smart-grid projects, and builds on the wiring already present in millions of homes, with no dependence on wireless communications.
Enlit 2025, Bilbao. We presented our indoor NB-PLC flexibility system at the PRIME Alliance stand, alongside El Sewedy Electrometer, validating compatibility with a leading meter manufacturer.
