Netherlands Records Nearly 90,000 Plug-in Home Battery Sales Through Third Quarter
Market data shows that registration rates for plug-in home batteries are higher than previously estimated by grid operators.
The Dutch market for plug-in home batteries saw 86,514 units sold during the first nine months of 2026. According to market figures from Sunergy Research, 33,085 batteries were sold in the third quarter, a slight decrease from the 33,574 units sold in the second quarter. Monthly sales reached 12,454 in July, dipped to 9,307 in August, and recovered to 11,324 in September.
Rolf Heynen of Sunergy Research attributed the August decline to seasonal patterns, noting that installation activity typically slows during holiday periods. He described the rebound in September as evidence of solid market demand. The 2026 growth represents a significant increase over the previous year, as more systems were installed in the first four months of 2026 than in the entirety of 2025, when 23,266 units were placed.
The data also challenged existing assumptions held by grid operators and the Energy Data Services Netherlands (EDSN) regarding registration rates on the national portal energieleveren.nl. While authorities previously estimated that roughly half of all home batteries were registered, Heynen’s research indicates the registration rate is rising, moving from approximately 37 percent in the first quarter to 54 percent in the third quarter.
Furthermore, the analysis contradicts the belief that plug-in batteries are rarely registered. A preliminary study conducted by Heynen and a grid operator found that about 50 percent of plug-in home batteries were registered in the third quarter. While Heynen acknowledged that the sample size for this specific scan remains limited, he stated that the trend toward higher registration is clear.
