As others have pointed out, our government is already picking winners and losers, through a wide range of subsidies to the fossil-fuel industry, including allowing them to externalize much of their cost onto the rest of us. But more importantly, in a place like Las Vegas, solar electricity is worth much more than its wholesale value because of its impact on peak capacity. Much of the cost of delivering energy through the electric grid is the cost of the grid, not the cost of the energy. This is especially true in a place like Las Vegas where much of the power is hydroelectric. The grid and all its components must be sized to handle the highest anticipated demand, which in the southwest occurs on hot, sunny days. But that's very close to when solar output peaks (peak solar output depends on the orientation of the panels, peak demand typically occurs around mid-afternoon). Solar energy goes into the grid close to the point of consumption. From the standpoint of the grid, it effectively reduces overall peak demand. It's common for capacity cost to be higher than energy cost, depending on the regional mix of generating resources. So at a minimum, solar producers should be paid for the service they provide in reducing overall peak demand. That value can easily be double the wholesale price.
