Hosting capacity assessment

Capacity type considered for hosting capacity information Firm
Description of what firm capacity means and the aspects that structure the definition Firm capacity means the capacity that doesn't need to be curtailed.
Description of the methodology that leads to firm capacity results Firm capacity refers to capacity that does not exceed the grid’s thermal or voltage limits and does not require curtailment, even in a non-intact grid. As the grid operator with system responsibility, Fingrid retains the right to curtail demand and/or production to maintain the system security of the grid.
Description of what flexible capacity means and the aspects that structure the definition Flexible capacity means the capacity that can be curtailed as detailed in the connection agreement.
Description of the methodology that leads to flexible capacity results Currently, flexible connections are used only as a temporary solution, as specified in the connection agreement.
Description for the criteria and methodologies used that lead to the published information Capacities are calculated in a way where they do not exceed the thermal, dynamic or voltage related limitations of the grid in intact system or if there is a fault. Calculations are done with load flow studies and dynamic studies. Values provided are rough estimates.
Main assumptions/disclaimers behind calculations The capacities published in the grid scope map are legally non-binding. Most of the values are estimations, and any project implementations may affect the connection capacity of other stations and/or power lines. The grid scope map currently only shows local capacity and does not consider the capacity at a regional level. Fingrid is currently working to add this information to the grid scope map. Published values are rough estimates. Fingrid does not guarantee that information in the grid scope map is comprehensive and error-free.

Additional information for connection request and hosting capacity information

Connection request procedure Connection requests can be made on Fingrids website (https://www.fingrid.fi/en/grid/grid-connection-agreement-phases/uusi-liityntakysely/). Projects must provide estimates of capacity (MW) type (demand, production, or both), location and the schedule of the project
Options available for the investors if the map shows 'no capacity available' in their interested area Investors may contact customer managers to inquire further
Connection request rules First-come-first-serve
Information published for volumes of connection requests/waiting lines Yes
