Capacity type considered for hosting capacity information
|
Firm and flexible
|
|
Description of what firm capacity means and the aspects that structure the definition
|
Firm capacity is not allowed to be constrained, redispatched, apart from protection automatics operation
|
|
Description of the methodology that leads to firm capacity results
|
Normal full grid operation used for simulations to determine generation hosting capacities. N-1 grid operation considered for consumption hosting capacities
|
|
Description of what flexible capacity means and the aspects that structure the definition
|
Flexible capacity is permitted to be restricted, redispatched in case of grid overloads
|
|
Description of the methodology that leads to flexible capacity results
|
Normal full grid operation with firm capacity assets online used for simulations to determine generation hosting capacities. N-1 grid operation with firm capacity assets online considered for consumption hosting capacities
|
|
Description for the criteria and methodologies used that lead to the published information
|
Full grid operation at 80% current capacity for network in N-0 condition. Grid operation at 90% current capacity for network at N-1 condition
|
|
Main assumptions/disclaimers behind calculations
|
While precise (developer stated) asset capacities are used for hosting capacity simulations, forecasted consumption is used for capacity simulations, which introduces additional uncertainty in the overall hosting capacity results. Situation with new network assets in the neighbouring TSO`s is not precisely known and introduces additional uncertainty in hosting capacity simulations.
