Electricity Tariff Types
Every Market Model, One Interface
We normalize complex energy market structures into a clean, actionable data format.
Static Tariffs
Standardized energy pricing models, including time-of-use (TOU) rates like day/night or peak/off-peak variations.
Dynamic Tariffs
Real-time, exchange-linked pricing. Access day-ahead electricity prices and EPEX Spot market data streams required for smart charging.
Synthetic Tariffs
Complex models calculated based on supplier rules or regulatory authorities - fully decoded and normalized for your API.
The tounify advantage
Complete coverage, by design
Feed-in & Grid Tariffs
Full coverage of feed-in and grid tariffs - not just consumption rates. Essential for solar, battery storage, and prosumer applications.
Postal Code to Grid Operator
Resolve a postal code to its local distribution operator and bidding zone. Filter available DSOs for a postal code, no lookup tables to maintain.
National & Local Fees
Electricity taxes, renewable levies and system charges are already inside the price we return. Some apply nationwide, others only in a single grid area or postal code - we resolve the most specific rule that applies, so you never assemble a levy table yourself.
Invoice-Based Gap Filling
Missing a tariff? Upload any electricity bill - we extract the rates and add them to the database. Coverage grows with every submission.

Data Sources
Where do we get the data from?
To provide the most accurate energy API in Europe, tounify aggregates electricity data from a broad mix of independent channels - official market feeds, national regulators, grid operators, and live supplier data - all cross-checked against each other for accuracy.
Automated Web Crawler
Our specially developed crawler which regularly searches the trained websites of energy suppliers for price changes and tariff updates.
Live Market Feeds
Direct connections to European power exchanges and market operators deliver day-ahead spot prices daily, keeping dynamic and exchange-linked tariffs continuously up to date.
Synthetic Tariff Replication
Programmatic replication of synthetic tariffs based on published energy formulas and supplier rules.
Regulatory Documents
Extraction of tariff information from regulatory public documents and official government sources.
Open Data
Integration of numerous European open-data platforms - national energy agencies, grid operators and address registries - to enrich and continuously verify our electricity prices, and to map postal codes down to the distribution grid operator that actually serves them.
Manual Updates
Manual verification using our specially developed tool for complex or hard-to-automate market cases.
One API, many sources. We continuously combine more than ten official market and regulatory data feeds spanning over a dozen European markets, alongside hundreds of energy-supplier websites monitored automatically - so no single source can distort a price.

Buy a dataset outright
Some teams need the data once, not as a live feed. We deliver parts of our database as a one-off purchase - CSV or JSON, in the same normalised schema the API returns, net of VAT, in major currency, per kWh. The sets below are examples rather than a catalogue; each one reaches further than the few entries we can show here. Priced on request.
European Grid Tariff Sets
Grid fees per distribution operator, each market kept in its own national structure rather than flattened into a lowest common denominator. Every row is linked to the document it was read from.
Examples
- German Netzentgelte with the §14a EnWG Modul 2 and Modul 3 variants, plus heat pump, e-mobility and storage heating tariffs
- Danish hourly time-of-use network tariffs, Dutch netbeheerkosten per connection size
- Austrian NE7, French TURPE
Regulatory Fee & Levy Register
Every statutory charge that sits between the wholesale price and the bill, carrying the scope it applies to and validity dates on every row, so past billing periods stay reproducible.
Examples
- National levies such as Stromsteuer, KWKG, Elafgift, Energiebelasting and accise
- Charges scoped to a single grid area, such as the Austrian Gebrauchsabgabe
- Charges scoped to a postal code, such as the Norwegian elavgift relief in the tiltakssone
Retail Tariff Snapshots & History
Point-in-time or historical extracts of the tariffs we track, versioned by the date each price took effect, so you can replay any past period.
Examples
- Consumption tariffs across the markets we cover
- Feed-in tariffs where suppliers publish them
- Static, dynamic and synthetic pricing models in one schema
Looking for something else? Our coverage runs well beyond the examples above - ask and we will tell you what we already hold. Anything still missing we collect on demand, as long as it fits our ontology: a tariff, a grid fee or a regulatory levy in a European market.

Frequently Asked Questions
Everything you need to know about the tounify API and our energy data.
tounify is a unified REST API that provides developers with direct access to comprehensive European electricity and grid tariffs. Instead of scraping dozens of provider websites or interpreting complex regulatory documents, you get clean, standardised JSON data for static, dynamic, and synthetic pricing models.
Yes, absolutely. We deliver exchange-linked dynamic tariffs, including day-ahead electricity prices based on the EPEX and North Pool spot markets. This is the exact data required to build intelligent Home Energy Management Systems (HEMS) or smart EV charging algorithms.
Dynamic tariffs (like exchange-linked prices) are synced daily as soon as the new spot market prices are published. Static and synthetic tariffs are continuously monitored by our automated crawlers and AI systems, ensuring you always operate on verified, up-to-date data.
tounify currently provides energy tariff data for 20+ European countries, including major markets like Germany, France, Italy, and Spain. We are constantly expanding our coverage. You can view the full list and live stats on our interactive coverage map.
Yes, that is one of our main use cases. By feeding our high-resolution tariff data into your algorithms, your applications can automatically schedule energy-intensive tasks (like charging an electric vehicle or running heat pumps) during the cheapest hours of the day.
No. You can request a test token completely free of charge and without a credit card. It gives you instant access to our API sandbox so your development team can evaluate the JSON endpoints and start building immediately.
