Europe's electricity grid is becoming a major bottleneck in absorbing Europe's rapidly expanding renewable energy, the electricity lobby says. The grid is designed to handle capacity in excess of demand, creating a slack space in the system that allows for the growth of clean energy production. This has resulted in a slew of renewable energy projects waiting to be connected to the grid, with Spain and Italy each having more than 150 GW of wind and solar capacity waiting to be connected to the grid. The European Commission is drawing up plans to push for more grid investment, while companies are restructuring networks to send power in different directions.
