Built-in data
For a region it knows, energy-cost fills in a contract: the distributor’s tariff, the fees, the taxes, the capacity rule and the time zone. For now that’s Flanders, for residential and small business connections with a digital meter.

Coverage
Section titled “Coverage”Fees and taxes start in 2022; distributor tariffs in 2024 or 2025, as above.
- Before a tariff’s first version, it has no price: a bill over that time is incomplete, or leaves that part out.
- After its last version, the last prices keep applying. Keep energy-cost up to date for new years’ tariffs.
Adding a region
Section titled “Adding a region”The energy-cost repository explains how built-in data is organised, and how to contribute the data for a region it doesn’t know yet. Until then, write the distributor, fees, taxes and time zone into the contract yourself.
