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

Columbia Water & Light - Solar Rebates

Columbia Water & Light (CWL) offers rebates to its commercial and residential customers for the purchase of solar water heaters and solar photovoltaic systems. These rebates are available for solar water heaters that were installed after April 2007, and for solar photovoltaic systems that were installed after June 2007. Following installation of any of these efficiency measures, applicable building or plumbing permits should be secured.

Customers are eligible for a rebate for installing solar photovoltaic systems. The rebate is $500 per kW. The utility provides a premium rebate for systems designed to perform best at peak times. Pre-project approval is

Renewable Energy Standard

In November 2008, voters in Missouri approved by a ballot initiative (i.e., via an initiated state statute) the Missouri Clean Energy Act, also known as Proposition C, which repealed the state’s existing voluntary renewable energy and energy efficiency objective and replaced it with a mandatory renewable portfolio standard (RPS). The RPS requires investor-owned utilities to use eligible renewable energy technologies to meet 15% of annual retail sales by 2021.

Eligible Technologies

Eligible renewable energy technologies include electricity produced using photovoltaics (PV); solar thermal; wind; small hydropower (10 megawatts (MW) or less); biogas from agricultural operations, landfills, and wastewater treatment

Net Metering

Eligibility and Availability

Missouri enacted legislation in June 2007 requiring all electric utilities—investor-owned utilities, municipal utilities, and electric cooperatives—to offer net metering to customers with systems up to 100 kilowatts (kW) in capacity that generate electricity using wind energy, solar-thermal energy, hydroelectric energy, photovoltaics (PV), fuel cells using hydrogen produced by one of the aforementioned resources, and other sources of energy certified as renewable by the Missouri Department of Natural Resources.

Systems must be intended primarily to offset part or all of a customer's own electricity requirements, and must be located on premises owned, operated, leased or otherwise controlled by

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

Building Energy Code

NOTE: Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

The Connecticut Office of the State Building Inspector establishes and enforces building, electrical, mechanical, plumbing and energy code requirements by reviewing, developing, adopting and administering the state building code. Compliance is determined through construction documents submitted to the relevant local building official showing detailed building data and features, and equipment systems governed under the code.

La Plata Electric Association - Renewable Generation Rebate Program

La Plata Electric Association (LPEA) offers an incentive, not to exceed the cost of the system, to residential and small commercial customers who install a photovoltaic (PV), wind, or hydropower facility. To be eligible for the rebate, the system must be grid-tied and located in LPEA's service territory. Systems 10 kilowatts (kW) or less are eligible for an upfront incentive based on the nameplate capacity and other factors. Systems greater than 10 kW are eligible for a performance-based incentive.

Payments are made every 6 months for the first 10 years of operation.
