Collaboration models for large-scale battery storage:

Working together for a safe transition to clean energy.

The expansion of wind and solar power causes significant fluctuations in the electricity grid which must be managed.

This is where battery storage systems come into play: they compensate for these fluctuations and contribute to the stability of the distribution network with grid-serving services. By integrating renewable energy, battery storage systems not only ensure grid stability but also enable cost-efficient use of the upstream grid and substation levels by using the excess energy on the control power market or intraday market.

Key points in the collaboration model:

Objective

Joint development, construction and operation of a battery storage project (> 15 MW) at a partner site

Structure

Establishment of a joint project company for the development, construction and operation of battery storage (VERBUND shares > 50%)

Collaboration

Division of roles between the two partners – contribution of know-how and parts of the project development/implementation according to each partner’s strengths

Maximise the use of specific strengths within the framework of a collaboration model

A collaboration model based on the individual strengths of the collaboration partners creates an environment in which collaboration is promoted, leading to better results. We use our respective strengths strategically to achieve our set goals more efficiently.
