What is NTC & elspot?

The transfer capacity is set, using a certain safety margin (stability, voltage etc), at the transmission levels, which will entail network collapse in the event of dimensioning faults. The NTC values between all the subsystems are given to Nord Pool Spot for day-ahead trading (Elspot) in its entirety.

What factors affect NTC calculations?

Two factors limit transfer capacities at values normally much below the thermal capacities: The network element within a transmission system that is the most sensitive to the load flow, compared to its operating limit (i.e. with a loading already quite near to its thermal limit) has the biggest impact on NTC calculations.

Do NTC values reflect real electricity transport possibilities?

NTC values, however, reflect real electricity transport possibilities in the meshed and internationally interconnected transmission systems. Two factors limit transfer capacities at values normally much below the thermal capacities:

What affects the NTC value in Norway?

The NTC value may also be affected by outages of major transmission lines in the Norwegian grid. This happens when the outage is close to cross-border connections and/or when it is impossible to relieve the congestion through counter-trade in the Norwegian system.

What is NTC & TRM?

They include the following notions : ð Net Transfer Capacity (NTC) ð Available Transfer Capacity (ATC) ð Transmission Reliability Margin (TRM) ð Notified Transmission Flow (NTF).

What affects the NTC value between two elspot areas?

The NTC value between two Elspot areas may be reduced due to thermal restrictions or voltage and stability limits. The NTC value may also be affected by outages of major transmission lines in the Norwegian grid.
