Powel Settlement solution supports players in the power sector with the process of compiling obligations (plan values, forecasts, measurement values and bilateral trade) and calculating the imbalance. Using a calculation engine, it is possible to verify that the imbalance settlement from the imbalance settlement responsible (eSett OY in the Nordic region) is correct.
“Powel Settlement registers the validity period of all the obligations to the balance responsible party. Based on the obligations, we use a calculation engine to calculate imbalances and other values that the customers need. This provides a better overview and saves time in the event of changes,” says Birger Morland, Product Manager at Powel.
An obligation is an object type that links the content of a time series with other relevant objects in a structure, such as a grid area. The tool enables the calculation engine to perform the necessary calculations based on the registered structure. For example, the content of a time series might be the sum of the electricity that the customers of an energy provider consume in a given grid area.
“The unique thing about Powel Settlement is that it is configurable. In other words, when rules change or when it is going to be used in a new context, all that is required is a new configuration of the system, not a further development,” says Morland.
The tool is currently used by customers throughout the Nordic region.
“There have been three major changes to the rules in Sweden over the past 15 years, but Powel has not needed to make any changes other than uploading new configuration data,” says Morland.
Powel Settlement compiles time series for imbalance settlement, which are obtained from forecasts, plans and trade. As a result, it is an advantage for the energy companies to have all the processes available in the same system.
Skellefteå Kraft AB is one of Powel’s customers, and they have experienced the following when using the solution:
Better control of the obligations before the start of deliveries and thereby lower imbalance costs.
Better control over the share calculation for the profile customers.
Easier calculation of imbalance costs in order to compare with invoices from TSO (Svenska Kraftnät).
Easier ways of sharing costs between the different suppliers.
