How it works
The day-ahead prices for tomorrow are usually known between 13:00 and 15:00. Since October 2025 the day-ahead market is traded per quarter-hour; some suppliers charge per quarter-hour, others per hour. You need a smart meter. The ACM points out that future tariffs cannot be predicted.
What the last 12 months looked like
Average day-ahead price in the Netherlands, 2025-10-20 t/m 2026-10-19: 0,107 € per kWh excl. VAT and tax; 401 hours had a negative price. Prices were on average lowest around midday (0,050 € per kWh at 13:00, local time) and highest in the evening (0,159 at 20:00). This is history, not a forecast. Chart and data: open data.
Solar panels and EV
Feed-in is usually compensated at the market price minus a fee, and solar output peaks when prices are often low. If you can move usage (for example charging an electric car), a dynamic contract can pay off; see dynamic contract and EV (Dutch).
How we calculate
For dynamic contracts our comparison tool shows an expectation based on the last 12 months, never a guarantee. We only calculate suppliers whose markup and fees we could verify on their own site; the others show as "not calculable" instead of an estimate.
Full Dutch version: dynamisch contract.
