June 7, 2012. Competition by Germany's regions to produce renewable energy as the country shifts away from nuclear and coal power could cause overcapacity if the process isn't coordinated. Chancellor Angela Merkel will meet with state premiers next week to discuss greater cooperation as regional governments develop plans to build wind and clean-energy capacity. Competing plans could cause overcapacity in the coming decades. The northern state of Schleswig-Holstein aims to produce by 2020 three times more energy from offshore wind parks than its population uses, and southern states such as Bavaria are planning more energy self-sufficiency. Overcapacity could be costly for consumers because German regulations require them to pay for unused power generation.
