Capabilities and costs for ancillary services provision by wind power plants. Deliverable D 3.1

This report is the deliverable of the third work package of the REserviceS project and describes the technical options and related costs for the provision of ancillary services specifically from wind energy technologies. It is focused on the set of ancillary services defined in the previous work package 2, shown in table 1 below. The information from this deliverable will be used as input to the case studies in subsequent work packages, which are expected to provide additional insights to the actual provision of ancillary services in transmission and distribution networks.
