In July 2010, SüdWestStrom — a collective of German municipal utilities — committed to buying a 70% equity stake in the project, with a group of investors backed by WV Energie to buy the remainder.

SüdWestStrom was ready to pour in up to €500m ($641m), but it had two demands, says managing director Bettina Morlok.

The first was that the Bard group would find surer footing.
