Technical data
Continuous communication between a customer and Fingrid is essential in every phase of the grid connection project. Electrical safety and operational reliability of a new grid connection are ensured by using technical data.
Required technical data during the grid connection project
Table: Technical data of a grid connection project
| Phase of the project | Required technical data (from customer to Fingrid) |
|---|---|
| Connectivity | Customer's contact information Basic information on a connection and a potential site Basic information on a transformer and a branch line Main grid information (from Fingrid to customer) |
| Planning | Network layout and major equipment location Single line diagram Realization of energy accounting Earthing system Coordinates Exact information on the transformer and the branch line Information on the relay protection and communication link |

Technical data on Customer Grid Connection will be submitted to Fingrid. When connecting a power plant, also Power Plant Data is required from the customer.
During the power plant project special requirements for the Operational Performance of Power Plants set by Fingrid must be taken into account.
