Electricity storage tool

Market participants play an important role in the development of flexibility required for the energy transition. TenneT has now developed a free Electricity Storage Valuation tool to further facilitate the understanding of key drivers and sensitivities in business cases for large-scale electricity storage.

How does the free tool works?

TenneT’s free tool allows users to independently analyse business cases for large-scale electricity storage. The tool uses a powerful method to determine the optimal dispatch of storage assets for specific applications, and includes a comprehensive set of technical and economic parameters for large-scale storage projects. It can also be used to perform financial analyses. As user you can select one of the predefined example cases, or define your own projects.
