Unofficial integration. It prices your electricity in Denmark as a Gladys energy contract: the hourly grid tariff of your grid company (netselskab), Energinet's transmission and system tariffs, the electricity tax (elafgift) and, if you want, the DK1/DK2 spot price with your supplier's markup, VAT 25 % included. Everything comes from Energi Data Service, the open data portal of Energinet, without an account or a key.
It has never been tested with a real Gladys contract nor a real Danish meter: the prices are checked against real answers of the API by the tests. Please report any difference with your bill.
Set up
- Install the integration (Gladys 5.3.0 or later). Nothing to fill in its configuration screen.
- In Energy > Contracts, create a contract with the template
"Energi Data Service (Denmark): tariffs and spot" and attach your meter:
- Grid company: its name ("Radius", "N1 A/S - 131") or its GLN (13 digits, on your bill). The list is below.
- Charge code: leave empty, unless the status asks for it (see below).
- Electricity supply:
grid_only(tariffs and elafgift only) orspot(plus the spot price every 15 minutes and your supplier's markup). - Price area (needed for
spot, no default):DK1west of the Great Belt (Jutland, Funen),DK2east (Zealand, Lolland-Falster, Bornholm). - Supplier markup (DKK/kWh without VAT, between -1 and 5): the "tillæg" of your supplier, added to the spot price.
- Monthly subscriptions (DKK/month, VAT included): the grid subscription, Energinet's and your supplier's, counted by Gladys as a fixed monthly amount. They are not read from DataHub.
- A device "Elpris <company>" appears in Discovery: it shows the price of a kWh now (DKK/kWh, VAT included).
The API allows about one request a minute: the integration asks one thing at a time, at least 65 seconds apart. After the creation of a contract, its prices come within a few minutes (Energinet's tariffs, then your company's, then the spot prices). Until then Gladys gets no cost for the intervals and asks again at its next run (never a zero).
How the price is computed
For each half hour, in DKK, VAT included:
kWh × (grid tariff of the local hour + transmission tariff + system tariff
- elafgift + [spot price + markup]) × 1.25
- Grid tariff: the household tariff ("Nettarif C") of your company, by local hour (Price1 = 00:00-01:00 Danish time). On the night of the autumn change the hour 02:00 happens twice: both take the same price, as Energinet says; in spring it does not happen.
- Energinet: transmission tariff (code 40000), system tariff (41000) and elafgift (EA-001), by day.
- Spot: DayAheadPrices of the area, 15-minute prices (since 1 October 2025), the mean of the two quarters of the half hour (Gladys sends half-hourly readings: the consumption is taken as even inside them).
- A company with several household tariff codes ("NT-01", "NT-10"...): without a Charge code, they are used only when they give the same price every hour of every day DataHub holds for them (and cover the same days). As soon as they differ anywhere, including one code published for a next season and not the other, the status asks for the Charge code and names the choices: a code is never picked because it is the only one with a price.
What Gladys cannot express, said plainly:
- A negative total (very negative spot price) costs zero: Gladys takes no credit for an interval. The "price now" of the device may be negative.
- No reduced elafgift (elvarme) or business VAT rules: the household prices.
- No spot price before 1 October 2025 (start of the 15-minute dataset).
- Subscriptions are your own monthly input.
A price that is not known (tariffs not read yet, no tariff for that date, a missing quarter of spot price) is never guessed nor counted as zero: the interval gets no cost and Gladys asks again.
Data and requests
- Tariffs: dataset DatahubPricelist, read for the companies your contracts use and for Energinet, then again once a day (a read that fails is tried again after an hour; the tariffs held stay in use, and the status says when they were not read again for 3 days). Kept in /data: the periods of the last 400 days only, so an interval older than 400 days gets no cost (never asked again for it).
- Spot prices: dataset DayAheadPrices, today's and, from 13:00, tomorrow's, plus any day Gladys asks for, history included (31 days in one request at most). A day is kept only whole, in /data, for 62 days after it was read (whatever its date: a month read for a recalculation is priced from there, not read again), 800 days per area at most.
- A 429 (too many requests) or a 5xx pauses every request for what the API asks, at least 2 minutes, doubled for each one in a row up to 6 hours; the pause is kept across a restart and shown by the status.
- Every request carries the integration's own User-Agent. No account, no key, no personal data is sent.
- The Test button shows, for 3 contracts at most, the company found, the date its tariffs were read and the parts of the price now. It makes no request.
Contains data used pursuant to "Conditions for use of Danish public-sector data" from the Energi Data Service portal (www.energidataservice.dk), Energinet. Energinet does not endorse this integration.
Grid companies
The directory shipped with this version (read on 2026-11-12): companies with a household tariff "Nettarif C" in DataHub. A GLN not in the list is accepted with its charge code (DataHub, column ChargeTypeCode).

Troubleshooting
- "tariffs of ... not read yet": wait a few minutes (one request a minute).
- "no tariff of ... for <date>": DataHub has no tariff of that code for that day; check the company and the charge code.
- "has several household tariffs that differ": fill Charge code with the one on your bill.
- "Energi Data Service asks to wait": the API limit was reached; nothing is asked until the time shown.
