In August 2007, Illinois enacted legislation (S.B. 680) requiring the Illinois Commerce Commission (ICC) to establish standards for net metering and interconnection for renewable energy systems by April 1, 2008. Although S.B. 680 only requires the promulgation of interconnection standards for "eligible renewable generating equipment," the ICC chose to take this opportunity to develop standards for all distributed generation up to 10 megawatts (MW). Final interconnection standards were adopted by the ICC in August 2008. In March 2010, the ICC established interconnection standards for Large Distributed Generation Facilities, or those over 10 MW. In December 2016, the ICC made

Utah enacted The Energy Resource and Carbon Emission Reduction Initiative (S.B. 202) in March 2008. While this law contains some provisions similar to those found in renewable portfolio standards (RPSs) adopted by other states, certain other provisions in S.B. 202 indicate that this law is more accurately described as a renewable portfolio goal (RPG). Specifically, the law requires that utilities only need to pursue renewable energy to the extent that it is "cost-effective" to do so. The guidelines for determining the cost-effectiveness of acquiring an energy source include an assessment of whether acquisition of the resource will result

In February 2008, South Dakota enacted legislation (H.B. 1123) establishing an objective that 10% of all retail electricity sales in the state be obtained from renewable and recycled energy by 2015. In March 2009, this policy was modified by allowing “conserved energy” to meet the objective. The objective applies to all retail providers of electricity in the state. However, as a voluntary objective (as opposed to a mandatory standard), there are no penalties or sanctions for retail providers that fail to meet the goal. Final rules related to renewable energy certificates (RECs), energy conservation measurements, and reporting requirements

Through the City of Healdsburg's PV Buy-down Program, residential and commercial customers are eligible for rebate on qualifying grid-connected PV systems. In keeping with SB1, (the California Solar Initiative mandating that utilities put into place programs to assure that 3000 megawatts (MW) of solar installations on homes is in place within 10 years) the incentive level will decrease annually over the 10 year life of the program. The program is currently on Step 8, with rebates of $0.62 per watt for residential and $0.59 per watt for commercial installations.  Larger systems may be installed, but the program will only reward

In 2022, the Houston City Council adopted the Municipal Building Decarbonization and Benchmarking Policy, requiring that city buildings target a 5% year-over-year reduction in electric power and natural gas consumption. This goal will be accomplished by implementing cost-effective measures to increase energy efficiency and decrease natural gas and other fossil fuel reliance through preventative maintenance, capital
improvement projects, and other measures. AP 3-41 outlines further guidance for energy performance and energy use intensity targets for existing city buildings,  new or replacement facilities, and major renovations. Energy use intensity (EUI) targets for electric power by building type include:
