Energy Portfolio Standard

Nevada established a renewable portfolio standard (RPS) as part of its 1997 restructuring legislation. Under the standard, NV Energy (formerly Nevada Power and Sierra Pacific Power) must use eligible renewable energy resources to supply a minimum percentage of the total electricity it sells. In 2001, the state increased the minimum requirement by 2% every two years, culminating in a 15% requirement by 2013. The portfolio requirement has been subsequently revised, most significantly by SB 358 (2019), which increased the requirement to 50% by 2030. In addition to solar, qualifying renewable energy resources include biomass, geothermal energy, wind, certain hydropower, energy

New Mexico Solar Easements & Rights Laws

New Mexico's Solar Rights Act (1977) and Solar Recordation Act (1983) allow property owners to create solar easements for the purpose of protecting and maintaining proper access to sunlight. The Solar Rights Act established the right to use solar energy as a property right. The solar right prevents neighboring property owners from constructing new buildings or planting new trees which would block their access to the sun.

The Solar Recordation Act describes the procedures for filing a solar right through the County Clerk's Office. The property owner seeking the solar right must give advanced notice to the adjacent property owners

Renewable Energy Systems Tax Credit (Corporate)

Utah's individual income tax credit for renewable energy systems includes provisions for both residential and commercial applications.

Legislation (section 5) enacted in 2007 extended these tax credits through at least 2012. On or before this time, and every five years thereafter, the Utah Tax Review Commission must review the tax credit and make recommendations as to whether the tax credit should be continued, modified, or repealed.
