Pricing with dynamic Day-Ahead Market prices

Stekker has the capability to determine the cost of a charging session by utilizing power markets, including EPEX, to calculate pricing. The company has been providing session pricing since the year 2021, and is currently handling a high volume of data, processing hundreds of thousands of events on a daily basis. This data processing allows for accurate and timely pricing of charging sessions, ensuring fair and competitive pricing for all customers.

There are two ways to price a charging session:

• When Stekker optimized the session, we have all the information to price the session.
• When you have meter readings you can send them to Stekker and we will calculate the price on demand.

Stekker has all Day-Ahead prices starting from 2018
