Abstract: With augmented demands on power grids resulting in longer and larger blackouts

combined with heightened concerns of terrorist attacks, trading institutions and policy

makers have widened their search for systems that avoid market failure during these

disturbing events. We provide insight into this issue by examining trading behavior at the

Copenhagen Stock Exchange during a major blackout. We find that although market

quality declined, markets remained functional and some price discovery occurred during

the blackout period suggesting that the NOREX structure of interlinked trading systems

combined with widely dispersed trading locations may be a viable means of protection

against market failure during massive power disruptions or terrorist attacks.
