Solar power in Utah
Solar power in Utah has the capacity to provide almost a third of all electricity used in the United States. Utah is one of the seven US states with the best potential for solar power, along with California, Nevada, Arizona, New Mexico, Colorado, and Texas. Utah allows net metering for residential systems up to 25 kW and up to 2 MW for non-residential users. Utah's renewable portfolio standard can best be described as a goal and calls for obtaining 20% of electricity from renewable sources by 2025 - if it is cost effective.
By 2011, with the 30% federal tax credit, prices have decreased to the point that they provide an attractive return on investment. Utah allows up to 25% $2,000 tax credit for residential systems and up to 10% $50,000 credit for commercial systems. St. George offers a $2000/kW(AC) rebate of up to $6,000 for residential systems, and up to $20,000 for commercial systems. A similar offer from Rocky Mountain Power of $1.55/watt (AC) has been fully subscribed for 2012.
Utah has the potential to generate 1,500,000 GWh/year from 826 GW of concentrated solar power (CSP) plants using 6,371 square miles - about 7.5% of the state. CSP has the advantage over photovoltaics of integrating storage for up to a day, allowing 24 hour operation, and allowing the hourly output to track demand, with the balance stored as heat. CSP is not able to compensate for seasonal changes, although in the southwest peak demand correlates with peak solar output, due to air conditioning loads. That is not the case for northern climates, where peak demand occurs in winter.
Solar Energy Zones
On April 20, 2012, the Bureau of Land Management identified 17 "Solar Energy Zones" with the best potential for priority solar development. Three of those are in Utah. In addition to the Solar Energy Zones, an additional 18,098,040 acres is available in Utah for solar application permits from the BLM, plus 1,962,671 acres with a variance.
