Jedlix and ENGIE strengthen Smart Charging partnership after successful lab testing day in Belgium

At the beginning of October, in the presence of the Belgian TSO Elia and the largest Belgian DSO Fluvius, Jedlix and ENGIE managed to successfully complete lab tests, at the ENGIE Laborelec test facilities, to demonstrate the technical capability of electric vehicles to balance the grid. Most important outcome of the test day is the possibility to show to Elia that a group of EVs can balance the grid and mitigate fluctuations in renewable energy.

ENGIE Jedlix Partnership

Since the announcement of the partnership and the successful launch of the Smart Charging service in Belgium in April this year, the testing day is a next step in the growing partnership between ENGIE and Jedlix. Belgium’s largest energy supplier and renewable energy producer ENGIE and Jedlix now joined forces with the IO.Energy ecosystem that has been initiated by all Belgian electricity grid operators. The ambition is to work together with multiple market players to offer new digital energy services to the Belgian households.

ENGIE currently has a proposition for EV Drivers in terms of a specific tariff, the ENGIE drive contract which is a tariff that  consists  of electricity coming from Belgium renewables. The role of ENGIE in this partnership program is to bring their customers who have an EV and such can offer the required flexibility. ENGIE will then valorize the flexibility with the help of Jedlix on the wholesale market. So that the value can be retributed to the customer. 

Erik van Eekelen – CTO Jedlix: ‘In the flexibility project the goal is that the Virtual Power Plant -consisting of many EVs- helps to balance the electricity grid. To do that we need to ensure that cars can respond quickly enough for both the network operator and Jedlix. ENGIE has a very innovative approach on this whereby Jedlix is really excited about working together with ENGIE as it allows us to scale our project by approaching many EV drivers.

Balance by participating in the aFRR market

The lab test focused on the demonstration of electric vehicles being able to balance the electricity grid in a close to real-time manner, more precisely by showing how Jedlix could participate in the automated Fast Restoration Reserve (aFRR). In a real commercial situation, this reserve of energy flexibility is activated by the TSO when a significant imbalance is observed on a national level between energy demand and energy production.

Due to the difficulty of predicting when these imbalances occur, grid operators are more and more looking for new reliable forms of flexibility that could help maintaining the equilibrium between supply and demand. Electric vehicles, hot water boilers and other household appliances could in the long term replace the traditional power plants that are currently expected to guarantee the grid balance.

With the number of electric vehicles on the Belgian roads expected to increase steeply over the upcoming years, the successful tests are   warmly welcomed since they reassured that ENGIE and Jedlix will be able to focus  on the seamless integration of electric vehicles in the electricity system.

EVs can balance the grid and mitigate fluctuations

Most important outcome of the test day is the possibility to show Elia that a group of EVs can balance the grid and mitigate fluctuations in renewable energy. The test findings are that the vehicles are sending out data as they should and are responding to market signals fast enough to provide balancing services.

Peter De Cock – ENGIE: ‘We can be very satisfied with the test of today. It is a very first time that we were able to test in practice if we can extract more flexibility from EVs in an isolated environment of ENGIE Laborelec. Important outcome is that EVs can be used for more complex products than shifting consumptions from one point to another. Our goal is to use EVs to balance the network and to balance ENGIE’s portfolio. Today is an important first step in that.’          

In the Netherlands several similar tests have been conducted and proved that EVs are able to provide balancing services. Now in Belgium the parties ENGIE, Elia, Fluvius and Jedlix are proving the same thing and are demonstrating that EVs are a reliable source of grid balancing services. Expectations of the next steps are high, the goal is to escalate the findings  towards the partners within the IO Energy project, like for example Elia.


ENGIE wants to grow the zero carbon transition both globally as locally. Our customers aim to transition to zero carbon emissions at their own pace and their own speed. We offer our unique expertise in client solutions and complex infrastructures to a wide range of small to large scale projects that will help the world transition to the energy of tomorrow, a zero carbon future.  The flexibility project is a perfect example of this transition. The project combines all the aspects of our business ecosystem as it combines electric mobility, local innovation on grid infrastructures and renewable energy systems without a loss of comfort for the end customer.


Jedlix teams-up with car OEMs such as Tesla, Renault, Jaguar, BMW and multiple energy partners to unlock the value of the flexibility of EVs charging process at scale, reduce the Total Cost of Ownership of the cars, and enable their sustainable insertion into the energy grid.

Jedlix app
