Energy Transition

The new reality of the energy market

The energy transition is changing the rules for buildings and their energy systems. Flexibility, energy efficiency and dynamic load management are now critical priorities.

The challenge of our time

In the building sector, air conditioning can account for up to 40% of electricity consumption. Renewable energy production isn't constant throughout the day. During the hours when solar generation drops, demand for air conditioning remains high.

This phenomenon shapes the Duck Curve, one of the key challenges facing modern electricity grids.

The challenge isn't just saving energy. It's managing demand intelligently at the right moment.
The “Duck Curve” phenomenon 2018 Morning Noon Evening

In the building sector, air conditioning accounts for up to 40% of total electricity consumption.

This new era creates a growing need for flexible demand management as renewable energy penetration increases.

Smart decisions that deliver better thermal comfort and more efficient air conditioning operation.

An innovative approach that upgrades facilities into active and flexible elements of the energy grid.

How it works

Easy installation. Simple to use. Smart operation.

With a quick installation, every air conditioning unit becomes part of a smart energy management system.

Easy installation

Easy installation of the controller

The smart controller is installed near the air conditioning unit in about 15 minutes, without extensive electrical work and without modifying the unit.

Simple to use

Simple to use with the existing remote control

Users continue to operate the air conditioning from the existing thermostat or remote control, with no changes to daily routines.

Smart operation

Smart energy-saving operation

The system continuously analyzes operating data and dynamically adjusts the air conditioning for optimal comfort with lower consumption.

The wholesale electricity price is published a day ahead, allowing for advance planning. Energy providers' dynamic tariffs are based on this. OverGrid AI automatically adjusts the setpoints of each facility, helping consumers achieve more efficient and cost-effective operation.

Why us

Why OverGrid AI

The difference isn't just in the savings. It's in how the solution is installed, how it operates, and the value it creates for your facilities.

No change for the userWorks discreetly in the background

The user experience stays simple and familiar, since the air conditioning continues to be operated via the unit's infrared remote control, with no need for training or changing habits.

The controller works in the background, receiving and decoding remote control commands and dynamically adjusting the system's operation so that consumption is reduced without affecting thermal comfort.

Low investment costOffers far more than a typical smart home device

The controller was designed from the ground up to support fluctuating energy prices and advanced energy management scenarios. A single device measuring 80mm x 80mm x 35mm integrates sensors and functions that, with a conventional approach, would require multiple separate IoT devices at a much higher total cost.

For example, a hotel room or office space would otherwise need separate devices such as a presence sensor, an infrared transmitter, an electricity consumption meter, a temperature and humidity sensor, plus a multi-function control panel or display.

OverGrid AI designed the controller to deliver maximum value at the lowest possible cost, resulting in a particularly attractive payback period.

Smart upgrade for air conditioning systemsStrengthens the circular economy

The OverGrid AI solution can be installed on existing air conditioning units from different manufacturers, without replacing equipment and without extensive interventions in the facility.

This upgrades existing units, extends their lifespan, and puts circular economy principles into practice.

Advanced controllerFinds the sweet spot between thermal comfort and savings

With built-in sensors and artificial intelligence algorithms, the controller allows the system to understand the operation of the air conditioning units in real time.

Based on this data, the system identifies the optimal operating point and reduces energy consumption while maintaining users' thermal comfort.

Ready for dynamic tariffsReceives signals from the Greek Energy Exchange and ENTSO-E

The platform leverages dynamic electricity pricing, adjusting the operation of air conditioning units based on the current wholesale energy market price.

At the same time, it lays the groundwork for future participation in demand response mechanisms, helping businesses reduce energy costs and actively contribute to grid stability.

No more relay cut-offsSafer management for next-generation air conditioning units

Energy savings in many facilities still rely on a simple relay. After a set time delay, the power relay cuts the electricity supply to the air conditioning unit. In modern units, this abruptly interrupts the refrigeration cycle without following the correct shutdown procedure. In several cases, this can even affect the warranty terms of the air conditioning unit.

OverGrid AI uses infrared commands exactly like the unit's remote control. For example, when the space is unoccupied, the air conditioning can first switch to ECO mode and then shut down normally, without the need for a relay.
