nearly half of Europe's energy
storage capacity. European grid operators need energy storage
to cope with an ever-mounting, always-shifting torrent of wind
power. See the connection? So does Norway. In December,
engineers will energize a new subsea power cable that will
begin to bridge the gap between need and opportunity, greatly
expanding European power systems' access to Norway's
hydropower-rich power grid.
The 240-kilometer cable across the Skagerrak Strait separating southern Norway and northern Denmark is Norway's
first new power link to Denmark since 1993. Called Skagerrak 4, its high-voltage direct current (HVDC) converters-the
electronic units at either end of the line that transform AC into
high-voltage DC and vice versa-are also the building blocks for
more ambitious cables from Norway to wind-power heavySPECTRUM.IEEE.ORG
