scope:

The purpose of this Technical Specification is to provide technical guidance for the connection of generating plants which can be operated in parallel with a public distribution network. This Technical Specification is intended to be used as a technical reference in connection agreements between DNOs and electricity producers. The requirements of this Technical Specification only apply to electrical machinery and equipment, irrespective of the kind of primary energy source. This Technical Specification applies to all three-phase generating units that meet all of the following conditions as an individual generating unit or as a cluster of generating units with a common point of connection: - converting any primary energy source into AC electricity; - connected to the MV network; - intended to operate in parallel with a public distribution network under normal network operating conditions. This Technical Specification defines interconnection requirements and a conformance test procedure. Island operation of generating plants, both intentional and unintentional, where no part of the public distribution system is involved is out of the scope of this Technical Specification. Safety of personnel is out of the scope of this Technical Specification. This Technical Specification recognises the existence of National Standards and Network Codes: these must be complied with. Only in the absence of these National Standards and Codes should the requirements of this Technical Specification be applied.
