Dutch residential neighbourhood at dusk with solar panels, heat pump and low-voltage infrastructure

Local control layer for electrical power

Using energy optimally, whenever the grid allows it.

Gridlinq controls heat pumps, batteries and other flexible energy assets locally and matches their power to generation, building demand and available electrical capacity.

From an individual connection to street and neighbourhood.

The challenge

More electrical devices. The same connection.

Electrification mainly adds power: a heat pump, a charge point and a battery together quickly demand more kW than a connection can deliver.

These devices operate independently and do not know each other's load. The result is simultaneity — peaks that neither the home nor the street needs.

01

Simultaneity

Heat pump, EV charger and hot-water cylinder start at the same moment.

02

Generation and demand diverge

Solar power arrives midday; heat demand peaks in the morning and evening.

03

Power headroom is unknown

Installations do not know how many kW are still free behind the connection.

Power

Not only energy. Above all power.

A connection does not have a kWh problem but a kW problem: at any single moment only a limited amount of power fits through it.

Gridlinq continuously determines how much power headroom is free and allocates it across the flexible assets — with a hard power limit as the boundary condition.

Gridlinq organises power.

The control layer

Not a dashboard. A local control layer.

Gridlinq measures at the connection and at the installations, computes the allocation locally and writes setpoints back through open protocols such as Modbus.

Price is one of the signals, not the starting point. The physical limit comes first.

TRADITIONAL EMS

price → optimise asset

Responds to a tariff, not to the physical headroom in the installation or the grid.

GRIDLINQ

capacity + demand + generation + comfort → coordinate assets

Controls on what is physically available and distributes it across multiple assets.

Thermal flexibility

Heat is flexibility.

A heat pump does not need to consume exactly the same amount of electricity every minute.

A building, floor heating and a hot-water cylinder can store heat temporarily within comfort limits.

Gridlinq uses this thermal flexibility to shift electrical power toward moments when solar power is available, the connection has headroom, the neighbourhood load is lower or energy is favourably available.

Comfort is the constraint. Flexibility is the result.

Grid

A feeder or LV transformer provides a capacity constraint or envelope. Gridlinq translates it into local flexibility.

Example: street level.

Nodes report their flexible power and each receive their own power limit. The allocation happens locally; the grid only provides the limit, not device control.

Technology

Local first. Cloud connected.

Control runs on a local controller. If the connection to the cloud drops away, the control keeps working within the configured limits.

01

Measure

P1, local metering, inverter, temperature and battery SOC.

02

Power limits, priority and comfort limits determine the allocation.

03

Control

Setpoints over Modbus TCP/RTU and APIs, with a defined fail-safe state.

Gridlinq Research

Old infrastructure. New function.

Gridlinq is researching whether decommissioned gas infrastructure can be reused as a route for fibre or data communication between homes and the local low-voltage infrastructure.
