All three tariff directions
Consumption, feed-in, and grid tariffs in one schema - essential for prosumer optimization.
Use Case
The Complete Tariff Data Layer for HEMS
Power your home energy controller with dynamic day-ahead prices, static TOU tariffs, and feed-in rates - all in one unified API.
The Problem
HEMS controllers need to know three things: what electricity costs right now, what it will cost in the next 24 hours, and what the grid pays for exported solar energy. Sourcing this data for 19+ European markets individually is a major integration burden.
The Solution
tounify normalizes all three tariff directions - consumption, feed-in, and grid - into a single JSON schema. Your HEMS logic receives the same structured data regardless of country or supplier.
What you get
Dynamic + static in one call
Switch between day-ahead prices and fixed TOU rates without changing your integration.
19+ European markets
Deploy your HEMS product across Europe without per-country data partnerships.
Synthetic tariff support
Complex formula-based tariffs (common in AT, DE, FR) decoded and normalized automatically.
