Compare tariffs

What would you pay in grid fees for a year on the hourly tariff, compared with the other tariffs you can choose? This page calculates it hour by hour for example homes, businesses and large assets, or for your own consumption. For the examples with an electric car, electric buses or a battery, you can also choose how they charge, and see what steering is worth on each tariff.

These are examples, not offers

The examples are made up. The hourly prices are simulated with today's price model, and several of the hourly tariffs are assumed. Even with your own data, this is an estimate, not what you would be billed. The amounts cover grid fees only, not the price of electricity. Homes are shown incl. VAT, businesses and assets excl. VAT.

Home

A villa with a fuse of at most 63 A, in Gothenburg.

Tariff
GNM63 – Småhus och företag, Max 63A	Standard	The power fee is based on the month's three highest hours, at any time of day.
GN6KW – Tidsindelad 6 kW, Max 63A	Time-of-use	The power fee only counts weekdays 07:00–20:00 in winter (November–March).
GN6KWST – Timpris 6 kW, Max 63A	Hourly price	Every hour has its own power fee per kW, see Price history.

The 6 kW in GN6KW and GN6KWST is the highest power, as an average over an hour, that the home has chosen to use. Homes with an electric car usually stay below it by setting the charger to a maximum: the car then charges with what the rest of the home leaves of the 6 kW. It still gets the same energy, just more slowly.

Going over the level: a month with any hour above it counts once. On the 4th such month in the 12-month tariff period on GN6KW, or the 10th on GN6KWST, the customer is moved to GNM63. The comparison counts the months in the year and moves the customer from the month after. A customer who goes over can raise their level before then, which starts a new 12-month period; that isn't shown here. The same goes for 10 and 14 kW, and the comparison assumes it for 43 kW on GN43KW and GN43KWVT.

GN6KWST isn't in the API yet. The comparison uses its preliminary prices, which have the same fixed fee and transmission fee as GN6KW.

A typical villa with an electric car

• The house has an air-to-water heat pump and uses 15,000 kWh a year: 5,000 kWh for lighting, appliances and cooking, 2,500 kWh for hot water and 7,500 kWh for heating. The heating follows the real outdoor temperature in Gothenburg in 2025, hour by hour, so the house uses the most on the days that were actually cold. Its highest hour is 6.0 kW.

• The car drives 12,000 km a year and uses 0.18 kWh/km, more when it's cold, plus 10% lost when charging: about 2,670 kWh a year. It charges every day with an 11 kW charger.

• When it charges: the car is home from 17:00 on weekdays and 14:00 on days off until it leaves at 07:00 the next morning, and charges in that time as fast as the charger and the limit allow. Choose above:

  • When it gets home: it starts charging straight away.
  • Optimised for GN6KW: it charges in the hours without GN6KW's power fee first, that is from 20:00 on weekdays and as soon as it gets home on weekends and holidays, so it has as many hours as possible to charge in.
  • Optimised for GN6KWST's hourly prices: it charges in the night's cheapest hours by GN6KWST's price, which are often late at night.

  What doesn't fit before 07:00 is charged the next evening.

• Three cases: GNM63 with the charger at full power, and GN6KW and GN6KWST with the charger limited so the whole home stays at or below 6 kW.

Business

Tariff
GNM63 – Småhus och företag, Max 63A	Standard	As for homes.
GN43KW – Tidsindelad 43 kW, Max 63A	Time-of-use	Like GN6KW, at a level of 43 kW: the power fee only counts weekdays 07:00–20:00 in winter.
GN43KWVT – Timpris 43 kW, Max 63A	Hourly price	Assumed, see below.
GNO63 – Normaltariff, Över 63A	Standard	For a fuse over 63 A. The power fee is based on the month's highest hour, at any time of day.
GN100KWV – Timpris 100 kW, Över 63A	Hourly price	Assumed, see below.

Office, max 63 A

An office or shop, open on weekdays 07:00–18:00, with a heat pump: 40,000 kWh a year. 12,000 kWh is standby around the clock (ventilation, servers, fridges), 20,000 kWh is used when it's open (lighting, computers, kitchen) and 8,000 kWh is heating, which follows the outdoor temperature and is turned down when it's closed. Its highest hour is 17 kW.

Grocery store, over 63 A

A grocery store, open every day 07:00–22:00: 300,000 kWh a year. 150,000 kWh is refrigeration, around the clock and more when it's warm. 110,000 kWh is lighting, ventilation and the bakery's ovens, which start an hour before opening. 40,000 kWh is heating; most of the heat is recovered from the refrigeration. Its highest hour is 76 kW, below the hourly tariff's 100 kW.

Asset

Large assets connected at 10 kV, such as depots, industries and batteries.

Tariff
HSP10KV – Högspänning 10 kV	Standard	The power fee is based on the month's highest hour, at any time of day. There is also a fee for the month's highest reactive power, per kVAr.
GN10KVT – Timpris, Högspänning 10 kV	Hourly price	Assumed, see below. It keeps HSP10KV's fee for reactive power.

Bus depot

A depot for 20 electric city buses: 2.2 GWh a year.

• The buses: 20 are in service on weekdays, 12 on Saturdays and 8 on Sundays and holidays. Each drives 220 km a day and uses 1.1 kWh/km, more when it's cold, plus 8% lost when charging: about 260–360 kWh a night. Each bus has its own 100 kW charger. They arrive between 19:00 and 22:00 and all leave at 05:00. Together they use 1.8 GWh a year.
• The depot uses 445,000 kWh a year: lighting and ventilation around the clock, the workshop on weekdays 07:00–16:00, and heat pumps that keep the bus hall at 10 °C.
• How the buses charge: at full power as soon as they arrive (up to 1.9 MW for the whole depot), at an even pace until 05:00 (up to 1.0 MW), or in the cheapest hours of the night by GN10KVT's hourly price, at full power. Choose above.
• Reactive power: 0.2 kVAr per kW, a power factor of about 0.98.

Battery

A grid-connected battery of 2 MW and 4 MWh that charges once a day and feeds the energy back into the grid later.

• Charging: it takes 4,444 kWh from the grid every day: 4 MWh plus 10% lost. Its cooling and control use 10 kW around the clock.
• How it charges: at full power from 00:00 (2 MW for just over two hours), at an even pace from 00:00 to 08:00 (0.6 MW), or in the day's cheapest hours by GN10KVT's hourly price, at full power. Choose above.
• Only the charging has a grid fee here. What the battery is paid for the energy it feeds back, and what it earns on the electricity price, aren't included.
• Reactive power: none; the inverter runs at a power factor of 1.

Assumed hourly tariffs

GN10KWST, GN14KWST, GN43KWVT, GN100KWV–GN400KWV and GN10KVT aren't in the API yet, and there are no preliminary prices for them. The comparison assumes that each has the same fees as its standard tariff, with the hourly price instead of its power fee per kW: GN10KWST and GN14KWST are based on GN10KW and GN14KW, GN43KWVT on GN43KW, GN100KWV–GN400KWV on GNO63 and GN10KVT on HSP10KV. That's how GN6KWST relates to GN6KW, but the real tariffs may differ. The hourly prices are the real simulated prices for each product, from Price history.

GN100KWV, GN150KWV, GN200KWV, GN250KWV and GN400KWV have the same hourly prices. With the assumption, the levels would cost the same, so the comparison shows the one that fits the highest hour: GN100KWV for the grocery store.

Your own data

Choose Your own data under Home, Business or Asset to compare the tariffs on your own consumption. Download the template for the year your values are from, fill in the kWh for each hour, save it as CSV and open it on the page. The file is read in your browser and isn't sent anywhere. Nothing is saved: it's gone when you leave the page.

• Years: 2022–2025, the years with hourly prices. Part of a year works too; whole months are compared. The tariffs' prices are 2026's, as for the examples.
• The file: one row per hour, or per 15 minutes. Column 1 is the date and time the hour starts in Swedish time, like 2025-01-31 07:00. Column 2 is the kWh used in the hour. Column 3, if you have a steerable load, is the kWh it used in the same hour, which is also included in column 2. Commas, semicolons or tabs, and decimal points or commas, all work, so a file saved from Excel in Swedish or English opens as it is. Negative values, like solar power fed into the grid, count as 0.
• Home: GNM63, and the time-of-use and hourly tariffs at the power level you choose: 6, 10 or 14 kW. It starts at the lowest level that keeps you on the time-of-use tariff all year, going over it in at most 3 months with the steerable load slowed down; above 14 kW it starts at 14 kW. The table shows how many months you go over, and whether you'd be moved to GNM63.
• Business: with a main fuse of at most 63 A, GNM63, GN43KW and GN43KWVT. Over 63 A, GNO63 and the hourly tariff at the level from 100 to 400 kW that fits your highest hour. It starts with the fuse your highest hour needs.
• Asset: HSP10KV and GN10KVT. The fee for reactive power isn't included, since the file has no kVAr values. It's the same on both tariffs.

Steering

A steerable load is something whose consumption can be moved in time, like an electric car's charging, a battery or a heat pump: what's in column 3. Each time it runs, that is the hours in a row in which it uses energy, it keeps the same energy. It never uses more in an hour than its highest hour in the file, as with a charger. You choose how long it can wait: it can finish up to 4, 8, 12 or 24 hours after it starts, but not after the next time it starts.

• When it ran in your file: it starts when it did.
• Outside the time-of-use tariff's power fee hours (for homes and businesses up to 63 A): it uses the hours in its window without the time-of-use tariff's power fee first (outside 07:00–20:00 on weekdays), the earliest first.
• In the cheapest hours by the hourly price: it uses the cheapest hours in its window, by the hourly tariff's price.

On the tariffs with a power level (GN6KW–GN14KW, GN6KWST–GN14KWST, GN43KW and GN43KWVT), it also charges more slowly so the whole consumption stays at or below the level, like a charger set to a maximum, and finishes later instead. Where the rest of the consumption is already close to or above the level, it can't always, and what doesn't fit in its window stays in the hours it was measured in. On the tariffs without a level, it uses its full power.

How it's calculated

• The year is 2025 for the examples: the hourly prices exist for 2025, so the consumption is for 2025 too, and the weekdays, cold days and price peaks line up. Your own data is compared in the year it's from. The tariffs' prices are 2026's, applied as if they had applied in that year.
• Every tariff gets the same consumption for the same example and steering, so the differences only come from the tariffs.
• The fee is calculated per month, as it is billed, with the same rules as the guide Calculate a monthly grid fee. The yearly total is the sum of the months.
• Public holidays count as holidays, also before 2026.
• The energy tax is the same on every tariff and is shown separately so that it doesn't hide the differences. It's the standard rate, 0.36 SEK/kWh excl. VAT (0.45 SEK/kWh incl. VAT). Reduced rates and exemptions, for example for industry, data centres or battery storage, aren't included.
• VAT: homes incl. 25% VAT, businesses and assets excl. VAT.
• The chart's week starts on the week where the hourly tariff's power fee is highest. Go to another week with the arrows, or pick any day of the year in the calendar.
