Double energy tax on home batteries: parliament asks for a fix
By Stefan Douw · Maker of Stekkerkompas
In early June 2026 the Dutch lower house filed several motions on the double energy tax and the VAT on home batteries. There is no ready-made arrangement yet, but the topic is now firmly on the political agenda.
What is at stake
A home battery that charges power from the grid pays energy tax on it. When the battery later feeds that power back, you do not get the tax back, and the next user pays energy tax on it again. The same kilowatt-hour is taxed twice or more without any extra consumption. Energy tax is roughly a third of the electricity price, so this drags on the return from trading with a battery. For large-scale storage this was settled in 2022, behind the meter at households it was not.
The motions
A motion by Grinwis (ChristenUnie), with Klos (D66) and Heutink, asks the cabinet to investigate whether a zero VAT rate on both solar panels and home batteries, as Germany has, would make sense here too, with a report around Prinsjesdag. A motion by JA21 (Van den Berg and Boomsma) asks for a workable solution to the double tax by the 2027 Tax Plan at the latest. The cabinet advised against that last motion, arguing that stored power is hard to track. The industry bodies Holland Solar and the NVDE have long pushed for an exemption at one of the two tax points.
What it means for you
Nothing changes on your bill for now: the double tax stays until there is an arrangement. If you are considering a battery now, this mainly matters for the expected trading return, which the tax makes lower than sellers sometimes suggest.
How we model it
We already include the tax and grid drag on exported power in the trading yield, so our figures reflect the situation as it stands. If an exemption or a zero VAT rate arrives, a battery's return goes up. Run your own situation in the calculator and set the imbalance yield to cautious to see how sensitive the result is.
