TSOs cannot stop worrying about security of supply
DON'T
EVEN IF YOU
• Goal: this regulation shall provide for an efficient power market and a satisfactory quality of supply in the power system. The regulation shall ensure that system
responsibility is executed in a societal rational way*, taking into account relevant societal and private
interests.
(author translation)
* Interpreted as maximizing social welfare

Regulation on system responsibility in the power system
(pursuant paragraph 10.6 of the Norwegian Energy law)
• Statnett favours (and uses) bidding zones
• BZs do not solve all problems and a BZ will seldom be a copper plate
• Creating copper plates for market purposes only is expensive and inefficient
• 70 % is a political compromise without root in physical realities
• No effect on physical flows
• At best neutral, at worst detrimental for social welfare
• TSOs spend efforts on solving 70 % instead of addressing real problems
• Huge volumes of redispatch mean
• TSO controlled, administered central dispatch (not market-based)
• Transfer of surplus from consumers to producers and traders
• Multinational preferable to national, proper design crucial

Norway performs satisfactorily
"For Finland, Norway and Sweden, a simplified assessment allows their cross- zonal capacities amount to be estimated at approximately 80% of the benchmark"
National performance with respect to the use of costly remedial actions

• Present procedures at Statnett are largely off- line/manual
• 24/7 data s ets do not exis t they w er e never c r eated
• Will improve when flow-based parallel runs start
• But this will still not be the data for the NTC calculations
• Moreover, note that
• Detailed grid data in Norway are confidential, and cannot be shared without formal guarantees for data security
• Detailed grid data in Sweden are secret
