With the further growth of weather-dependent renewable generation systems with solar panels or wind turbines, it is less and less obvious that local peaks in electricity generation or use will fit within the available grid capacity. In addition, the conditions for offsetting solar electricity will become less favourable over the next 10 years. In Germany, because of the ending of the very luxurious conditions for electricity feed-in, a growth in the number of home batteries has been taking place for a few years now. This is going up by 10-thousands of systems a year.

Dutch company iwell develops, builds and sells smart battery systems. The systems capture peaks of electricity use and (renewable) generation and thus ensure that the grid is not overloaded. This allows more room for the transmission of sustainable energy and at the same time our customers save substantially on connection costs.

Iwell's vision is: "Clean and affordable energy for everyone; one of the greatest challenges of our time. The energy transition is begging for change. That is why many parties are having endless discussions on how things can and must be done differently. But this all takes so much time..."

"Iwell does things differently! We accelerate the energy transition and build tomorrow's energy supply today. Together, we make the world a more beautiful place. More sustainable, cleaner and greener. With Cube, our smart battery, we are already taking steps towards a more beautiful world today"

On 21 April, Michiel Wiggers, technical director at iwell, explained how battery systems work using a number of example case studies. These included an apartment renovation where electric cooking is used and there are large heat pumps on the roof and a football club, which was actually not allowed to install solar panels because the local grid operator would not accept the feed-in.

iwell deploys systems with a capacity of 10 kW or 30 kW, which already creates considerable extra space on the grid, due to peak smoothing.

It also discussed the evolving regulations surrounding battery systems.

There were 117 registrations for this webinar and more than 85 participants, who took the opportunity to ask questions.

The intro was provided by Richard Overkamp (KIVI Elektrotechniek) and the presentation by Michiel Wiggiers (iwell).
