Wind and solar, the primary and volatile power sources of the energy transition, require more grid flexibility, which can be provided, for instance, by storage facilities. Energy storage technologies open opportunities for use in future energy markets and for a range of other system and grid-related purposes. For this reason, TSCNET shareholder TenneT, the Dutch-German transmission system operator (TSO), is involved in many research initiatives on flexibility, e.g. to explore power-to-gas applications, electric vehicles and end-user participation in the energy system of the future.
TenneT has now introduced a new interactive assessment tool for storage investments, on which Tim Meyerjürgens, COO of TenneT, comments: “We want to support the electricity storage market. Storage facilities are an important source of flexibility for us to stabilise the grid. In the end, this can help to reduce the need for future grid extension.” Especially when it comes to questions concerning levies, charges or taxes as well as revenue opportunities, the TSO aims to assist market players and to create transparency.
This is why the tool, developed by TenneT in cooperation with Navigant Consulting, was specially designed for the economic evaluation of investments in grid-connected storage facilities. It compares technologies or types of financing and estimates maximum revenues based on an optimised use of storage units in different markets. The user can define individual key parameters or customise predefined projects to obtain a detailed breakdown of the results in terms of net present value and cash flow.
