The market for electricity contracts has changed dramatically in recent years. Many households are abandoning traditional fixed-rate agreements to capture record-low prices on the dynamic spot market instead.

Which contract type best suits your living situation? Here we examine the advantages and disadvantages of the three most common contract structures, and how pairing the right electrical hardware maximizes your cost savings.

Which Electricity Contract Fits Your Home?

Choosing the ideal contract depends primarily on your total annual electricity consumption, whether you live in a house or an apartment, and how flexibly you can shift your major energy usage across the day.

1. Hourly Rate Contracts (The Smart Choice for Homeowners)

With an hourly rate contract, you pay the exact spot price determined by Nord Pool during the specific hour you use power.

Main Advantage: Highly profitable if you own an electric car charged overnight, or a heat pump with smart controls. Nighttime electricity rates are frequently a small fraction of daytime peak rates.
Key Consideration: Requires the ability to shift high-power loads. If you consume heavy power between 17:00 and 20:00 on cold winter days for cooking and laundry, your average price may rise compared to standard plans.

2. Fixed-Price Contracts (Security and Predictability)

With a fixed contract, you lock your kilowatt-hour price for a duration of 1 to 3 years. You know exactly what every kilowatt-hour costs regardless of weather conditions, geopolitical tensions, or spot market spikes.

Main Advantage: Absolute financial predictability. No unexpected surprises on monthly utility bills during harsh winters.
Key Consideration: Over long periods, fixed-rate contracts are almost always more expensive because power companies include a risk premium to cover market fluctuations.

3. Variable Monthly Contracts (Average Rate Without Automation)

A traditional variable contract bills you a weighted average spot price across the entire month. You never need to monitor the time of day when using appliances.

Main Advantage: Simple and convenient. Reflects general market downturns without requiring any automation or behavioral changes.
Key Consideration: You cannot capitalize on cheap night electricity to charge an EV or heat your home. This plan is ideal for apartments and small households with modest power consumption.

Combine Hourly Rates with Smart Technology for Maximum Savings

To extract full value from an hourly rate contract, installing the right electrical infrastructure is essential:

Smart EV Chargers (Zaptec Go or Easee Charge Up): Connected chargers can be configured via smartphone apps to charge only when spot electricity is lowest, cutting vehicle charging expenses significantly.
Automated Heating Controls: Smart relays and thermostats from Plejd or heat pump controllers preheat the home before morning price spikes take effect.
Dynamic Load Balancing: Prevents your main fuse from tripping when multiple heavy loads operate simultaneously during off-peak night windows.

Frequently Asked Questions About Electricity Contracts and Hourly Rates

When is electricity cheapest during the day?

Electricity prices on Nord Pool are generally lowest between 00:00 and 05:00 at night when industrial activity and domestic demand are minimal. On windy nights with high wind generation, spot rates can even turn near zero.

What is the primary difference between variable monthly and hourly rates?

With a traditional variable contract, every subscriber pays the same monthly average rate. With an hourly rate contract, your usage is metered and billed hour by hour, directly rewarding you when you shift loads to off-peak periods.

Must I replace my electricity meter to switch to hourly billing?

No. Almost all Swedish residences are already equipped with smart meters. When signing an hourly contract with your energy provider, the grid operator remotely switches your profile to hourly metering without replacing hardware.

What contract is recommended for a home with an EV and a heat pump?

For a detached house equipped with an electric vehicle and modern heat pump, an hourly rate contract paired with a smart EV charger and load balancing offers the most significant financial savings.
