Price history

See how the hourly prices have varied, hour by hour, from autumn 2021 to the end of 2025. Use the history to understand the price pattern before you build: when in the day prices are high, how much they vary between seasons, and how often they're 0.

The hourly prices apply from December 2026, so the history is simulated: each day's prices were calculated the same way as today, from a forecast of the load on the grid, with today's price model. It shows what the prices would have been if today's hourly prices had applied then. No customer has paid these prices.

Prosumers

A prosumer, a customer who also feeds electricity into the grid, has two hourly products: one for the electricity they take from the grid (consumption) and one for the electricity they feed into it (production). The production product follows from the consumption product:

Consumption	Production
GN6KWST, GN10KWST, GN14KWST	GNMPFT
GN43KWVT, GN100KWV, GN150KWV, GN200KWV, GN250KWV, GN400KWV, GNO400KWV	GNSPET
GN10KVT	None

Choose one of these consumption products and select Show the production price for prosumers to see both prices in the same charts. Production prices are negative, because the customer is paid for the electricity they feed in, so they're drawn below the zero line. Download CSV then also has the production prices.

What the history shows

The numbers below are for GN6KWST (Småhus timpris 6 kW), excluding VAT. The other products follow the same pattern at a different level.

• Winter is what costs. November to March make up 85–93% of each year's power cost, if you use the same power every hour. In summer the price is 0 almost all the time.
• The night is almost free. On winter weekdays the price averages 0.06 SEK/kW between 00:00 and 06:00, and 1.23 SEK/kW between 08:00 and 20:00, about 20 times as much. The highest prices are usually around 10:00–12:00 and 17:00–19:00.
• Weekends are cheaper. A winter weekend costs about a quarter of a winter weekday on average.
• Many hours cost nothing. 36% of all hours in 2022–2025 have the price 0, from 25% in 2022 to 42% in 2025.
• Peaks are rare, but high. The highest hour was 13.65 SEK/kW, on 20 January 2022 at 13:00. On only 271 of the 1,461 days in 2022–2025 did any hour cost more than 1 SEK/kW.
• Production has negative prices with the same pattern over the day and the year.

So the most value comes from moving power away from winter weekday daytime, and especially from the few days with very high prices.

Get the history from the API

The history is available in UAT. Fetch a period with fromIncluding and toExcluding (see Choosing a time range), for example all of January 2025:

curl "https://api.uat.goteborgenergi.cloud/gridtariff/v0/prices?product=GN6KWST\
&fromIncluding=2025-01-01T00:00:00%2B01:00&toExcluding=2025-02-01T00:00:00%2B01:00"

• Fetch at most a year per request, and wait a moment between requests. The API limits how many requests you can make in a short time and answers 429 Too Many Requests when you go over.
• Sort the hours by start. The API doesn't always return them in time order.
• The history only exists in UAT. Production has prices from the day hourly prices launch onwards.

If you only need the numbers, use Download CSV above. It gives you the selected product's prices for the whole year, excluding and including VAT.

About the data

• The history starts on 28 September 2021 at 02:00 and runs to the end of 2025. All products have the same period.
• The prices are per kW, the same as in the API's priceExVat and priceIncVat. VAT is 25%.
• Products with exactly the same prices share one price curve. The chart shows the same thing for those products.
• The chart uses a copy of the API's data, fetched on 20 October 2026. The API is the source if they ever differ.
