TimmyHEurope Backs Supergrids
December 2nd 2008 07:25
Recent efforts show hope for regional transmission planning for renewable power.
Last month, the European Commission (EC) called for construction of regional electric transmission connections across the North Sea, around the Baltic region, and around the Mediterranean Sea, to distribute solar and wind power to and across Europe. It's all part of a plan to boost renewable energy from 8.5 percent of European energy consumption to 20 percent by 2020--and even more thereafter.
But the EC, the European Union's executive body, acknowledges that getting these so-called supergrids built will mean forging new agreements between European countries for transmission planning and investment--much as the United States needs more cooperation between states to, for example, move wind power from the Midwest to major cities. "The wind power which consumers demand cannot be delivered without new networks," the EC report says, and "there is little strategic planning" between nations to build the required connections.
However, several recent developments suggest that progress on transmission between European nations is possible. This summer, for example, a negotiator appointed by the EC convinced France to accept a new transmission connection with Spain, breaking a 15-year impasse over expanding power exchanges between the countries. Use of high-voltage DC (HVDC) technology will enable planners to bury the new line and thereby overcome local opposition to conventional overhead AC transmission lines.
Christian Kjaer, CEO of the European Wind Energy Association, a Brussels-based trade group, calls it a "major breakthrough" that shows how Europe can overcome entrenched opposition to such interconnections. "It's a good example of why we need more than a national approach," says Kjaer.

Wind boost: This wind farm in Galicia, Spain, is among the developments that make Spain the largest wind-power producer in Europe. Europe’s goal of reaching 20 percent renewable power by 2020 will require new transmission links to balance wind’s fluctuating power output with conventional power sources across large regions. A new link between Spain and France will help.
