It was exacerbated in recent weeks by maintenance on an interconnector with Victoria.
Along with projects already under way in Scandinavia, there are plans for new interconnectors between Denmark and the Netherlands, and there are early discussions about building an interconnector with Britain, said Anders Eldrup, the chief executive of Dong Energy, the biggest Danish power utility.

Work could start on an interconnector from Poland to Lithuania in 2018; until then Latvia's abundant storage provides some insurance against strong-arming.

But last week SSE said it would not be able to commission work on an interconnector, which would transmit power generated by renewable projects on the Western Isles to customers on the mainland, before 2017.
"However, the final decision on purchasing a machine for testing will, in part, be based on our expectation of there being an interconnector cable being laid between the Shetland Islands and the Scottish mainland".
The margin was also boosted by a breakdown in the UK's electricity interconnector with Ireland, which usually results in more electricity flowing out than in.
That would cut demand, and encourage generators to revive mothballed plants and increase imports of subsidised nuclear electricity via the interconnector with France.Anybody want a used nuclear industry?Since neither the safety nor the supply arguments for spending more taxpayers' money on the company hold water, the government should let it go under.
Severe storms tore down three major transmission lines in the state's mid-north, overloading the main interconnector with Victoria and causing a power outage across all of SA. "Multiple supercell thunderstorms produced damaging to destructive wind gusts, including at least seven tornadoes, very large hailstones and locally intense rainfall," the report, released on Monday, said.
