This page is designed to help you find out whether Prezio.eu is good and if it is the right choice for you.
Most electricity price APIs in Europe give you spot prices and stop there. But the real cost at any address includes DSO grid tariffs, retailer charges, taxes, TSO fees, and authority surcharges - all varying by country, region, and consumer type. Getting that full picture meant scraping hundreds of regulator PDFs and DSO portals yourself.
Prezio is a REST API that delivers the complete electricity price stack across European markets - not just spot, but grid charges, non-commodity costs, and regulatory fees, resolved per location.
Coverage: 2000+ energy companies across 16 European countries including Germany (800 companies, 700 grid operators), Great Britain, Belgium, the Netherlands, Denmark, Sweden, Norway, Finland, Austria, and more. Retailers, DSOs, and authority tariffs.
What you get: - Real-time full cost via /live and /calculate - spot + grid + non-commodity in one response - Location-aware DSO grid tariff resolution across hundreds of operators - Non-commodity cost breakdown: electricity tax, TSO charges, local levies - Webhooks on tariff changes and expirations - no polling - Free sandbox for development and testing
Who it's for: EV smart charging software, heat pump controllers, home battery management, solar self-consumption optimization, energy management systems, tariff comparison platforms, flexibility aggregators, and EV charging session reimbursement tools. How it's different: Spot-only APIs cover wholesale market prices. Prezio is the API for the full delivered cost of electricity - grid operator network charges, retailer markups, time-of-use tariffs, and all regulated cost components combined. One API call returns what the end consumer actually pays per kWh.
Integration: REST API with webhooks and an embeddable React onboarding widget for end-user location and tariff setup. Free sandbox account available - contact for production pricing.

Developers and product teams building applications where electricity cost matters for the end user. Typical use cases include EV smart charging software, heat pump controllers, home battery management systems, solar self-consumption optimization, energy management platforms, and tariff comparison services. Our customers are usually B2B companies - hardware manufacturers, energy retailers, or EMS providers - who need accurate, location-specific electricity pricing data to power scheduling algorithms, billing logic, or cost displays across European markets.
We started Prezio because we kept running into the same problem from different angles. Coming from energy utility & retail, and eMobility / EV charging sector (Orsted, Circle K, TotalEnergies), we faced that getting accurate, granular electricity pricing data across European markets was a mess - every country has different tariff structures, different regulators, different DSO portals, and none of it is standardized. Teams building energy products were either spending months collecting this data themselves or just approximating. We figured if this was painful for companies with dedicated energy expertise, it had to be worse for the average dev team trying to build a charging app or a heat pump controller. So we built the API we wished existed. Prezio is based in Copenhagen, Denmark, and backed by Innovation Fund Denmark.
Our early customers include energy startups building white-label EMS (Energy Management System) platforms, energy tariffs comparison tools, EV charging apps, hardware manufacturers deploying smart home devices / heat pumps / EV chargers / solar PV and batteries, and energy apps needing retail tariff data.
Cloud-hosted on Microsoft Azure (EU region) for low-latency access and European data residency. REST API serving JSON with webhook support for real-time tariff change notifications. Data accuracy is maintained through a combination of direct API integrations, AI-powered data agents, and human tariff specialist review - ensuring reliable coverage even where source data is unstructured or inconsistent. The onboarding widget is available as a React npm package, via CDN, or as an iframe - embeddable in any web or mobile app (iOS, Android) with a single line of code and full custom styling support. API documentation hosted on Mintlify.
Most electricity data APIs in Europe only cover wholesale spot prices. Prezio provides the full delivered cost of electricity - spot prices, DSO grid tariffs, retailer charges, taxes, levies, and authority surcharges - resolved per location and consumer type, in a single API call. We collect and standardize tariff data from 2000+ energy companies across 16 European countries, including +700 grid operators in Germany alone. The result is that developers building energy-aware applications don't need to scrape regulator PDFs or maintain DSO portals themselves - they get one consistent data format across all markets. Data accuracy is ensured through a combination of direct API integrations, AI-powered data agents, and human tariff specialist review.
It depends on what you need. If you only need wholesale spot prices (which account for ~30-40% of someone's total electricity bill), free options like ENTSO-E can work. If you need forecasted spot prices and carbon intensity data, Electricity Maps is the go-to. But if your product needs to know 100% of the electricity costs at a specific address - including grid charges, taxes, and levies on top of the spot price (or any contract that is not dynamic, which is still the norm in most countries) - that's where Prezio fits. We handle the country-specific complexity (seasonal tariff structures, fuse-based pricing tiers, conditional authority charges) in the API layer, so your team doesn't have to build and maintain that logic. One integration covers multiple European markets. For end-user-facing products, our onboarding widget can be embedded in any web or mobile app with a single line of code to handle location and tariff setup.
