Clean Energy and Energy Efficiency Portfolio Standard

North Carolina's Clean Energy and Energy Efficiency Portfolio Standard (CEPS), originally established as a Renewable Energy and Energy Efficiency Portfolio Standard (REPS) by Senate Bill 3 in August 2007, requires all investor-owned utilities in the state to supply 12.5% of 2020 retail electricity sales (in North Carolina) from eligible energy resources by 2021. Municipal utilities and electric cooperatives must meet a target of 10% renewables by 2018 and are subject to slightly different rules. In February 2008, the North Carolina Utilities Commission (NCUC) issued an order adopting final rules to implement the CEPS. 

Eligible Technologies

Eligible energy resources include solar-electric

City of Scottsdale - Green Building Policy for Public Buildings

As of Dec. 6, 2022, the Scottsdale City Council has adopted the 2021 edition of the International Energy Construction Code (IECC) and the International Green Construction Code (IgCC) with amendments as mandatory codes. The effective date for the International Energy Conservation Code (IECC) is Jan. 7, 2023.

In 2005, Scottsdale approved a green building policy for new city buildings and remodels. The resolution requires all new, occupied city buildings of any size to be designed, contracted and built to achieve certification by the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Program at the "Gold" certification level

North Carolina Solar Rights

Cities and counties in North Carolina generally may not adopt ordinances prohibiting the installation of "a solar collector that gathers solar radiation as a substitute for traditional energy for water heating, active space heating and cooling, passive heating, or generating electricity for residential property."(§ 160D-914.a)* 

However, this does not prohibit development regulation regulating the location and screening of solar collectors as described previously, provided the regulation does not have the effect of preventing the reasonable use of a solar collector for a residential property. (§ 160D-914.b)

Nor does this prevent development regulation that would prohibit the location of solar collectors

Green Energy Technology in Public Buildings

Green Energy Technology

Enacted in June 2007, HB 2620 introduced a unique requirement for installing solar systems for public buildings. In 2012, SB 1533 amended the requirement to allow the use of any Green Energy Technology (GET). As of January 1, 2020, GET has been defined as energy systems that employ:

  • Geothermal electric
  • Geothermal direct use
  • Solar electric
  • Solar thermal
  • Passive solar
  • Battery storage equipment paired with the above

Eligble Alternative technologies include:

  • Woody Biomass*
  • Energy Use Efficiency**

The law requires public agencies to spend at least 1.5% of the total contract price of an eligible public building on green

State Building Energy Standards

In June 2007, South Carolina enacted legislation (the Energy Independence and Sustainable Construction Act of 2007) to promote effective energy and environmental standards for construction, rehabilitation and maintenance of buildings in the state; to improve the state's capacity to design, build and operate high-performance buildings; to create new jobs; and to increase the state's energy independence. In June 2008, the state enacted additional legislation, H.B. 4766, requiring state agencies and public school districts to develop energy conservation plans towards an ultimate goal of a 20% reduction in energy use by 2020, as compared to 2000 levels.

Sales and Use Tax Exemption for Solar and Geothermal Systems

Connecticut enacted legislation in June 2007 (H.B. 7432) that established a sales and use tax exemption for solar energy equipment and geothermal resource systems. H.B. 7432 added passive and active solar water-heating systems, passive and active solar space-heating systems, and solar-electric systems to the list of exempt technologies. The sales and use exemption covers both the equipment related to eligible systems, and labor (services) relating to the installation of eligible systems. The exemption has no expiration date.

Consumers purchasing the eligible equipment or services must present form CERT-140 to the seller at the time of purchase. Certification Form CERT-140 is

Lakeland Electric - Solar Water Heating Program

Lakeland Electric, a municipal utility in Florida, offers solar-heated domestic hot water on a "pay-for-energy" basis. The utility bills the customer $34.95 per month regardless of use. The $34.95 monthly charge is a bulk energy purchase. The water heater is owned and maintained by the vendor. The utility provides program policy management, meter reading, billing and collection services. Residents must live in the Lakeland Electric service territory, and all candidate homes are subject to a site inspection to determine suitability.

The program serves as an incentive to residential customers to utilize solar energy by:

  • making solar energy affordable to all
