Is a supergrid necessary for Europe to meet its renewable policy goals?

摘要

A European supergrid is increasingly seen as a fundamental component to enabling the region to achieve its renewable energy policy goals. We are already seeing the limits to transmission capacity for renewable energy being reached in many countries, and we are even seeing clean energy production being curtailed in some regions by the inability of the grid to transmit the energy to demand centres. In the short term, much more could be done by grid operators to make a level playing field for renewables. Existing transmission capacity could be used much more effectively in maximising energy production through, for example, transmission capacity auctions or a system of grid access based on carbon or other sustainability criteria.
