Valpo Solar will not raise local electricity prices. In fact, the cost of solar power has dropped by more than 70% since 2010 and is now one of the lowest-cost options for electricity generation.
When comparing unsubsidized, levelized costs of energy, utility-scale solar energy is comparable in price to wind energy and natural gas combined-cycle power, and it is significantly more cost-effective than coal or nuclear power. Solar power also has the benefit of producing electricity during the times of day when demand and power costs are the highest. On a midsummer afternoon, for example, when homes and businesses are running their air conditioners at full power, a solar facility is generating at full power as well, which helps close the gap between electricity supply and electricity demand. This has the effect of lowering electricity costs across the board.
