Does the storage system require changing the farm's connection conditions?

Yes, adding storage to an existing farm requires changing the conditions to a hybrid installation. The procedure typically takes 90–150 days.

What configuration is optimal for wind?

4 h (0.25C). The wind profile is less predictable than PV, so a longer discharge duration better covers periods of low generation.

Can the storage system operate alongside an auction-based support scheme?

Yes, but energy from the storage system must be separated by a dedicated metering setup from energy covered by the support scheme.

Energy storage at a wind farm

Short answer

For a 20 MW wind farm, a typical storage system is 10 MW / 40 MWh in a 4-hour configuration. The main benefit is reduced imbalance costs from forecast error and full utilization of connection capacity during low-wind hours.

The problem: generation variability and imbalance

Wind generation forecast error translates directly into balancing market costs. A 2–4 h storage system allows closing the position within an hourly horizon and limiting deviations.

Hybrid installation

A shared point of connection for the farm and the storage system maximizes use of connection capacity. During low-wind hours, the storage system delivers energy, using the unutilized headroom of the connection.
