Fixed vs Variable vs Dynamic Energy Contracts in the Netherlands
8 min read · Updated Oct 2026Compare fixed, variable and dynamic Dutch energy contracts: price certainty, flexibility, solar panel impact, EV and heat-pump considerations, and which type may suit your household.
Fixed Energy Contracts: Price Certainty for 1–3 Years
A fixed energy contract locks in your electricity and gas rate for a set period, typically 1, 2, or 3 years. Your per-unit price stays the same regardless of wholesale market movements, which makes monthly costs predictable. All Dutch energy suppliers — including Essent, Vattenfall, Eneco, Greenchoice and others — offer fixed contracts. The main trade-off is that if market prices fall during your term, you continue paying the higher fixed rate until the contract expires.
- Rate is locked for the contract term (1–3 years)
- Price certainty protects against market spikes
- You may miss out if wholesale prices drop during the term
- Cancellation before the end date may incur a fee — check the terms
Variable Energy Contracts: Monthly or Quarterly Adjustment
A variable contract means your energy supplier adjusts the per-unit price periodically — usually monthly or quarterly — based on wholesale market conditions. This gives you flexibility: you can switch suppliers at any time with short notice, and you benefit automatically if prices fall. The trade-off is that prices can also rise quickly, and your monthly costs are less predictable than with a fixed contract.
- Rate adjusts monthly or quarterly with the wholesale market
- No long-term commitment — switch with one month's notice in most cases
- You benefit from price drops automatically
- Monthly costs are less predictable than a fixed contract
Dynamic Energy Contracts: Hourly Electricity, Daily Gas
Dynamic contracts, available in the Netherlands since 2020, charge you the actual wholesale electricity price for each hour and the daily gas price. A smart meter is required. Providers such as Frank Energie, Tibber, and EnergyZero offer dynamic contracts. Prices can be very low or even negative during periods of high renewable generation, and higher during evening peaks or low-winter-supply periods. Dynamic contracts can be cheaper on average for households that can shift consumption, but they expose you to real-time price volatility.
- Electricity priced per hour; gas priced per day, based on wholesale markets
- Requires a smart meter
- Can be cheaper if you shift usage to low-price hours (overnight, midday solar peaks)
- Prices can spike during high-demand periods or low renewable generation
- Additional supplier fee per connection per month typically applies
Solar Panels and Your Contract Choice
If you have solar panels, your contract type affects how you are compensated for surplus energy fed back to the grid. Under the current salderingsregeling (net metering), available through 31 December 2026, your annual production is offset against your annual consumption, so the contract type mainly matters for any net energy you buy. From 1 January 2027, full net metering ends and feed-in compensation replaces it. The rate you receive for exported electricity may differ by supplier and contract type, so comparing feed-in tariffs becomes more important when choosing a contract.
- Net metering (salderingsregeling) runs through 31 December 2026
- From 2027, feed-in compensation replaces annual net metering
- Feed-in rates may differ by supplier and contract type — check before signing
- Dynamic contracts may offer lower export prices during negative-price hours
EVs, Heat Pumps and High-Electricity-Use Households
Households with an electric vehicle, heat pump, or other high electricity consumption may benefit from a dynamic contract if they can shift usage to off-peak hours. Charging an EV overnight or running a heat pump during midday solar surplus can take advantage of lower hourly prices. However, if your usage is largely fixed (for example, heating needed during evening peak hours), a fixed or variable contract may provide more predictable and potentially lower overall costs. A smart EV charger or programmable heat-pump thermostat is needed to fully benefit from dynamic pricing.
- Dynamic contracts can suit EV owners who charge overnight or during midday lows
- Heat-pump users with flexible scheduling may benefit from off-peak dynamic pricing
- Households with inflexible peak-hour usage may prefer fixed or variable contracts
- A smart charger or thermostat is needed to automate off-peak scheduling
What Expats Should Check Before Signing
Before signing an energy contract in the Netherlands, check the contract duration and cancellation terms, the per-unit rates for electricity and gas, the standing charges (leveringsvergoeding and transport fee), and whether the contract is in English. Verify whether a connection fee or monthly dynamic platform fee applies. Compare the total estimated annual cost, not just the per-unit rate, using a comparison tool like Gaslichter or Energievergelijk. Some suppliers offer English-language customer service and app interfaces, which can be valuable if you are not yet comfortable in Dutch.
- Check contract duration, cancellation notice and early-termination fees
- Compare total annual cost (per-unit rate + standing charges), not just the unit price
- Confirm whether the supplier offers English-language service and billing
- Verify any monthly platform or connection fee for dynamic contracts
Comparison at a Glance
| Feature | Fixed | Variable | Dynamic |
|---|---|---|---|
| Price per unit | Locked for contract term | Adjusted monthly/quarterly | Hourly (electricity) / daily (gas) |
| Price certainty | High — rate does not change | Low — adjusts with market | Very low — changes hourly |
| Flexibility to switch | Limited — cancellation may incur a fee | High — typically one month notice | High — short notice period |
| Protection from price spikes | Yes — full protection | Partial — rate adjusts periodically | No — exposed to real-time prices |
| Benefits from price drops | No — locked until term ends | Yes — automatic adjustment | Yes — immediate reflection |
| Smart meter required | No | No | Yes |
| Typical contract term | 1, 2 or 3 years | Indefinite (monthly/quarterly) | Indefinite |
| Suitable for load shifting | No benefit from shifting | Limited benefit | Strong benefit if you can shift usage |
Which Contract May Fit You?
These are general indicators only — the best choice depends on your usage pattern, risk tolerance and contract terms available at the time. Always compare current offers before deciding.
| Your situation | Which contract may fit |
|---|---|
| You want predictable monthly costs and dislike surprises | Fixed contract may suit you |
| You want flexibility to switch and can tolerate some price variation | Variable contract may suit you |
| You have an EV, heat pump or flexible usage and can shift consumption | Dynamic contract may suit you |
| You have solar panels and low net consumption | Any type — compare feed-in tariffs, especially from 2027 |
| You use most electricity during evening peak hours | Fixed or variable contract may provide more predictable costs |
| You plan to move within a year | Variable or dynamic — check cancellation terms on fixed contracts |

Assumptions & Limitations
This guide describes general contract types and their characteristics. Energy prices, supplier offerings, tax rates and regulatory frameworks (including the salderingsregeling and feed-in compensation) change over time. Always verify current terms with your supplier and check official sources such as the ACM (Authority for Consumers and Markets) and Rijksoverheid for regulatory updates.
