3 Buckle Up! Cheapest Solar Ever? Austin Energy Buys PV From SunEdison at 5 Cents per Kilowatt-Hour An unprecedentedly low price for a large solar project This is one of the lowest, if not the lowest, reported prices for contracted solar that we have seen... Austin Energy's net subfive cent price does not include any state PTC, according to Monty Humble of energy development firm Brightman EnergyLLC Humble added, "Based on our analysis, it can be done. There's not a whole lot of profit in it The 5-cent price falls below Austin Energy's estimates for natural gas at 7 cents, coal at 10 cents and nuclear at 13 cents. The utility points out that it approved a 16.5-cent price for the Webberville solar plant in Source: 3
