Solar power in Nevada is growing due to arenewable portfolio standard which requires 50% renewable energy by 2030. The state has abundant open land areas and some of the best solar potential in the country.[1]
The number and size ofphotovoltaic power stations in Nevada has been growing rapidly since 2010. As of 2018, the largest is the 552 MWCopper Mountain Solar Facility nearBoulder City, which is a group of co-located units, each sized up to 250 MW.[2][3][4][5] Another 250 MW unit has been approved for construction, which could make it thelargest solar facility in the United States.[6][7] Earlier notable solar facilities in the state include the 14.2 megawatt (MW-peak), 140 acreNellis Solar Power Plant; and the 64 MW, 400 acre concentrating solar thermal power plantNevada Solar One, which both began operation in 2007.
Nevada has also been a leader in low-cost solar electricity generation, establishing several milestones. The Nellis plant was able to provideNellis Air Force Base with electricity for only 2.2 cents/kWh—compared to the 9 cents they were paying Nevada Power—by sellingrenewable energy credits (RECs).[8] In 2015, the 100 MW Playa Solar 2 project—to be constructed byFirst Solar with a 20-year power purchase agreement withNV Energy - was proposed for $0.0378 perkilowatt-hour. This was below the lowest price of $0.046 available the previous year from the 100 MWBoulder Solar plant.[9] In 2018, the 300megawatt (MWAC)Eagle Shadow Mountain Solar Farm was approved for construction with flat rate of $0.02376 per kilowatt-hour throughout its 25-year PPA term, which could establish a new record.[10][11][12]
Solar photovoltaic and/or thermal power has also been proposed to augment somegeothermal power plants in the region—which struggle to meet demand during mid-day peak hours due to their higher bottom of thethermodynamic cycle—since the solar plants will peak at that time.[13][14][15]
As of February 2022, there are 26 large proposed projects in Nevada, totaling over 21 GW of capacity, or five times the state's existing solar capacity. These projects also include more than 17 GW of energy storage.[16] Half of these were proposed inNye County, which would be enabled by two new transmission lines, though some are close toDeath Valley National Park.[17]

Prominent Nevada-based solar installation companies include 702 Energy Savers, Radiant Solar, Summerlin Energy, Bombard Renewable Energy, and Hamilton Solar.[18]
Nevada had 129 MW in private installations ofrooftop solar in 2015.[19]
The federal Residential Energy Efficient Property Credit (income tax credit on IRS Form 5695) for residential PV and solar thermal was extended in December 2015 to remain at 30% of system cost (parts and installation). There is no maximum cap on the credit, the credit can be applied toward thealternative minimum tax, and any excess credit (greater than that year's tax liability) can be rolled into the following year.[20][21]
Net energy metering rules were changed in December 2015, unfavorably for homeowners having or considering rooftop solar, and were applied even to existing installations. Some major installers, including SolarCity, Vivint, and SunRun, withdrew from the Nevada market.
After a public outcry, the earlier favorable rules weregrandfathered for up to 32,000 customers whose systems were active or had a pending application by December 31, 2015.[22][23][24][25][26][27] ThePublic Utilities Commission of Nevada approved bill AB405 in 2017 to restorenet metering.[28]

(*) Preliminary data from Electric Power Monthly.
Beginning with the 2014 data year, the Energy Information Administration has estimated distributed solar photovoltaic generation and distributed solar photovoltaic capacity. These non-utility scale estimates project that, Nevada, generated the following additional solar energy.
| Year | Summer capacity (MW) | Electric energy (GWh or M kWh) |
|---|---|---|
| 2014 | 49 | 86 |
| 2015 | 120.4 | 186 |

Instead, we can turn to 8minutenergy's 300-megawatt Eagle Shadow Mountain Solar Farm, which clocks in at a flat rate of $23.76 per megawatt-hour throughout its 25-year PPA term.
