Solar is not cost-effective today for applying power after the sun sets (duck curve) or at night. Wind is not cost-effective at supplying power on calm days. If they were required to build the rest of the system to be reliable (longer interconnects, batteries, etc) it suddenly wouldn't be cost-effective, this explaining why energy cost continues to go up while this supposedly cheap power ramps up.
