Watch the webinar: New method predicts future battery usage for grid operators

Energy Storage NL organized, in collaboration with Euroforum and Enexis a webinar on June 9 titled ‘’Future battery profiles: how grid operators are trying to predict battery behavior in 2035’. With more than 250 participants, the webinar explored the future management of batteries and their societal benefits. Grid operators use this assessment to develop their investment plans, among other things.

The webinar served as a preview of The Energy Storage Event organized by Energy Storage NL and Euroforum on December 3, 2026, at Aviodrome Lelystad.

Calculation method

Maarten Staats of Enexis kicked off the webinar by explaining the rationale behind the new calculation method, which was developed in collaboration with Liander and Stedin. The method focuses on a battery’s annual profile. The annual profile is difficult to determine due to the wide variety of deployment strategies. These vary by battery type and also change over time.

Five strategies have been defined: imbalance, intraday, day-ahead, peak shaving, and self-consumption. In addition, there are four different types of batteries: standalone, colocation, business, and residential batteries. Depending on the type, each battery has a specific mix of strategies, which will also vary in the future.

Battery Deployment Strategies

Bart van der Holst, also from Enexis, then went into greater detail about the method and the different annual profiles for each battery type. He also shared some preliminary conclusions based on this calculation method. The analysis shows that deployment strategies other than imbalance have a significantly smaller impact on the power grid. Furthermore, batteries usually have relatively little effect on demand peaks and are almost always beneficial for feed-in peaks. Finally, this grid impact varies significantly from station to station.

These conclusions are based on the “baseline impact” of batteries, i.e., without taking into account any regulations or contractual terms set by grid operators.

Discussion

Following the presentations, there was time for an in-depth discussion of the questions participants had asked in the chat during the webinar. This also allowed market participants to respond to the grid operators’ findings and provide their input for the next steps. In the upcoming Energy Storage NL working groups, the grid operators will further discuss their optimized results with ESNL members.
