Optimise for the customer's actual energy price

Build the relevant purchase price

For a Belgian dynamic contract in the supported Fluvius region, the supplier formula adjusts the market price with a factor and offset. The calculation then includes the applicable network cost, green electricity and CHP contributions, federal energy contribution and excise, followed by VAT. These are categories for that configurator, not a universal formula for every country. Check the selected contract, date and tariff sheet before accepting the proposed values.

Keep purchase and export separate

The amount received for exported energy can differ substantially from the price paid for imported energy. Configure both sides, including relevant supplier fees and timing rules. With the advanced configurator, explicitly include network charges, taxes and VAT in the formulas; the generic fixed-price form also uses the totals you enter. Country-specific wizards handle some components automatically, so follow the selected wizard's instructions to avoid missing or counting costs twice.

Give each quarter hour its real value

Choose the market and price interval that match the customer's contract. Where quarter-hour day-ahead prices apply, display 15-minute steps rather than a smooth price curve. Time-dependent tariff rules can alter the resulting purchase or export price. Battery losses and configured wear influence whether storage cycling is worthwhile; they are separate from the purchase tariff itself. Recheck the configuration when the contract changes using the current tariff sheet as your reference.

Validate the tariff before planning

• Select the right country, currency and contract configurator.
• Match supplier formulas, dates and intervals to the tariff sheet.
• Verify purchase and export totals, fees, taxes and VAT.
• Recheck settings after a contract change.
