Spot Pricing

The most complex price structure follows the spot price in addition to price groups defined by a price per kWh or minute. In this pricing system that follows fluctuating electricity prices (data is taken from source like Nordpool, SEMO-PX), it is possible to define a master price (per kWh or Minutes) and add additional fees entries.

1. price = SPOT_HOUR * ((VAT/ 100) +1)
2. price = price * (PERCENTAGE / 100)
3. price = (price < MIN) ? MIN : price
4. price = (price > MAX) ? MAX : price
5. price = price * ((ADDITIONAL_PERCENTAGE / 100) +1)
6. price = price + TARIFF_HOUR
7. price = price + ADDITIONAL_ABOSLUTE

Example

Pricing:

• A charge session starts at 10:31 and ends at 11:15
• Premium (fixed) 1,10 DKK/kWh
• Premium (percentage) 50% of spot price
• Consumption:
• 7kWh in the 10-11 timeframe
• 3kWh in the 11-12 timeframe
