This contract, a massive $7 billion deal to supply solar energy “from renewable and alternative energy production facilities that are designed, financed, constructed, operated and maintained by private sector entities,” involves some 22 separate companies. Taking the form of a multiple-vendor, indefinite-delivery/indefinite-quantity, firm-fixed-price, non-option, non-multiyear contract, vendors will bid against each other to sell solar energy to the U.S. Army in response to individual “task orders” issued by the U.S. Army Corps of Engineers.
