Buffalo developer Louis Ciminelli and three other defendants face corruption charges over the awarding of contracts for several large-scale projects, including the solar plant at RiverBend in South Buffalo. Ciminelli, a major donor to Gov. Andrew M. Cuomo, is charged with wire fraud and conspiracy to commit wire fraud. The trial will also cast a spotlight on the $750 million RiverBend solar plant in Buffalo, one of the state projects Ciminelli won, and will decide whether bids were rigged in contracts related to construction projects funded by the Buffalo Billion. Paul Shechtman, a Manhattan lawyer, represents Louis Ciminelli
