The Challenge
Don’t become an energy price expert. Plug into one.
Grid tariffs change constantly. Regulations reverse, DSOs rename their tariff structures, political winds shift. Building your own solution means rebuilding every time something shifts. That’s not a scalable solution, that’s a maintenance contract with yourself.
No standard.
Every DSO sets their own structure. Endless combinations, scattered documentation.

Months of work.
You need specialists who understand energy markets and algorithm design and they never stop.

The Engrate Way
11 calculation functions to rule Cost of Energy
Implement 11 calculation functions: Import, Add, Subtract, Multiply, Sum, Clip and a few more. Engrate provides the exact combination for each asset, each DSO, each country. Grid tariffs change, your code doesn't.
HOW THE API IS USED
Engrate in Action
Don't ask your team to become cost experts. Let them plug into one.
VPPs & Optimisers
Your team shouldn't be tracking DSO announcements.
Engrate gives them every energy cost component described by the same building blocks. Every operator. Every market. Transparent from input to answer.
Industrial
Solve your energy cost problem without an expert team.
Every market has different rules. The rules keep changing. You can build a team that tracks regulatory changes across every market - or use Engrate. One integration, every cost component, full auditability. Faster time to new markets, zero maintenance burden.
Asset Owners & Developers
Understand your energy costs today.
Asset owners: Most optimisers still only optimise for spot price. With Engrate, find out what savings you're missing. Power tariffs alone can be a substantial share of your energy bill.
Renewable developers: Use Engrate to optimize your green field development. Calculate the cost of energy based on your project specifications.
Q&A
Questions & Answers
What is Cost of Energy?
Cost of Energy (CoE) is the complete cost of running an energy asset including power tariffs, transfer fees, energy tax, fixed fees and feed-in tariffs. Spot price alone represents only a fraction of your actual energy costs. Optimising for CoE instead of spot price alone can unlock substantial savings across your entire asset portfolio.
Do I need to understand energy tariffs to use Engrate?
No. The API handles the complexity — you work with a simple, consistent data model regardless of market or operator. Clear documentation tells you exactly what data to provide, with no guessing and no domain rabbit holes. For AI-assisted development, point your coding agent at our docs and MCP server and go from zero to a working, verified integration without first spending months learning Nordic grid fee structures.
Why only 11 functions?
We designed a minimal set of algebraic functions including import, add, subtract, multiply, sum, clip, filter and a few more that can represent every tariff structure in Europe. It's based on Static Single Assignment (SSA), the same principle compilers use. Complex calculations, simple implementation. You implement the 11 functions once; Engrate provides the exact combination needed for every DSO and every subscription.
Which countries and DSOs do you support?
We cover all 170+ Swedish DSOs for power tariffs, and German and Dutch electricity markets for settlement and scheduling. More markets are continuously being added. Query by coordinates, DSO name, Metering Grid Area or address.
What data do I need to provide?
Energy consumption and production data in 15-minute intervals, your grid subscription details, and — for higher voltage assets — subscribed power and reactive power. Engrate handles all the tariff logic, DSO lookups, and calculations.
How easy is it to get started with Engrate?
We'll start with a workshop to understand your needs. Since our integrations are pre-built and plug-and-play, you start seeing value within days of connecting and not months of building. We handle the complexity, you get immediate results.
Does Engrate provide hands-on support, or am I on my own?
For developers, we provide clear, well-maintained API documentation that makes integration straightforward. And when something needs immediate attention, you'll reach real people who understand your business. We're in this for the long haul — your success is our success.
Why should I trust a startup like Engrate?
We get it, it's a fair question. Engrate is backed by experienced investors and built by professionals with a proven track record of solving integration challenges at enterprise scale. We're here to deliver reliable, long-term value. Get in touch and discover why leading energy companies place their trust in Engrate.
What exactly do you mean by AI-Native API?
We wrap a Model Context Protocol (MCP) server around all our APIs. MCP is the native tongue of AI and LLMs. By connecting to our MCP, your AI agents can directly understand and reason with our energy integrations: No translation layers, no prompt engineering around data formats. Just connect and get 25 years of energy market expertise instantly available to your AI.
