Interconnection Standards

The Public Regulation Commission (PRC) adopted revised standards and procedures for the interconnection of generating facilities in New Mexico in July 2008.

Rule 569 applies to all qualifying facilities (QFs) under the federal Public Utility Regulatory Policies Act, which generally includes all renewable energy systems and combined heat and power (CHP) systems up to 80 megawatts (MW) in capacity.

Rule 568 applies to renewable energy systems and CHP systems up to 10 MW in capacity. The purpose of Rule 568 is to simplify the interconnection requirements for QFs up to 10 MW and to encourage the use of small-scale, customer-owned

New York City - Property Tax Abatement for Photovoltaic (PV) and Energy Storage Equipment

In August 2008, the State of New York enacted legislation allowing a property tax abatement for photovoltaic (PV) system expenditures made on buildings located in cities with a population of 1 million or more people. This limits the abatement to systems installed within New York City. Eligible buildings include all real property except utility real property. As originally enacted, the in-service deadline for eligible systems was December 31, 2012. However, in August 2012 the abatement was extended to systems placed in service through December 31, 2014, at a reduced rate. In September 2014, S.B. 746 extended the compliance period for

Property Tax Abatement for Solar Electric Systems

In August 2008, North Carolina enacted legislation that exempts 80% of the appraised value of a "solar energy electric system" (also known as a photovoltaic, or PV, system) from property tax. For the purposes of this assessment, the term "solar energy electric system" means "all equipment used directly and exclusively for the conversion of solar energy to electricity." This incentive is effective for taxable years beginning on or after July 1, 2008.

A Memorandum sent to County Commissioners in February 2011 clarified that residential PV systems that are not used to generate income or in connection with a business may

Energy Standards for State Buildings

In May 2013, Oklahoma enacted H.B. 1990, repealing the high-performance building certification program.

The State is still required by statute to adopt planning and construction standards for state buildings that conserve energy and optimize the energy performance of new buildings. The standards must reduce dependence on imported sources of energy through energy efficiency and local and renewable energy sources.

The standards must also authorize the Office of Management and Enterprise Services to pursue ENERGY STAR designation to demonstrate energy efficiency in public buildings.

Energy Standards for Public Buildings

Note: As of July 2023, Missouri state facilities under construction or renovation, and commercial buildings purchased or leased by state agencies, must comply with the 2015 IECC, pursuant to the Section 8.812 requirement that standards be at least as stringent as the latest version of the IECC.

Energy Conservation Goals

In April 2009 Missouri’s Governor issued Executive Order No. 09-18, requiring all state agencies whose building management falls under the Office of Administration to adopt policies designed to reduce energy consumption by 2% each year for the next 10 years.

Energy Efficiency and Sustainable Design in New School Construction

The Ohio School Facilities Commission (OSFC) administers funds appropriated by the Ohio General Assembly for the construction of new schools and renovations of existing schools. In September 2007 the OSFC approved a resolution (Resolution 07-124) requiring that all new school construction projects not already in the design phase achieve LEED for Schools Silver certification, with a goal of achieving LEED for Schools Gold certification. Credits under LEED Energy and Atmosphere Category are considered to be "preferred" investments, although the regulation sets no specific standard for this category outside of the existing certification prerequisites.

The overall program is expected

GMP Solar Power

Green Mountain Power, an investor-owned electric utility operating in Vermont, offers a credit to customers with net-metered photovoltaic (PV) systems. In addition to the benefits of net metering, Green Mountain Power customers with a PV system less than 15 kilowatts (kW) receive a credit of $0.053 per kilowatt-hour (kWh) of electricity generated by the system. PV installations larger than 15 kW receive a credit of $0.043 per kWh. This credit is available to all customers of Green Mountain Power. The incentive does not have a specified duration or expiration date.

In order to net meter, customers must first apply for

High Performance Building Standards in New State Construction

In January 2008, New Jersey enacted legislation mandating the use of high performance green building standards in new state construction. The standard requires that new buildings larger than 15,000 square feet constructed for the sole use of state entities should be designed and managed to meet high performance green building standards. The law allows for exceptions from specific requirements in cases of practical difficulty. These exceptions only apply to the specific requirement in question and do not extend to all requirements. With some exceptions the state is also required to purchase Energy Star products when available, a provision adopted in

High-Performance Building Requirements for State Buildings

In March 2008, South Dakota enacted legislation mandating the use of high-performance building standards in new state construction and renovations. The law was updated in 2021, lessening the previous standards and removing the requirements for renovations. The policy now requires that new state buildings achieve the U.S. Green Building Council's LEED certified rating (decreased from silver rating), a two-globe rating under the Green Building Initiative's (GBI) Green Globe rating system, or a comparable numeric rating from another accredited sustainable building certification program. The law applies to all new construction projects by state agencies, departments, or institutions that has a cost

City of Plano - Green Building Policy for Municipal Buildings

In January 2007, the City of Plano adopted a policy to "finance, plan, design, construct, manage, renovate, and maintain its facilities and buildings to be sustainable." This policy applies to new construction and major renovations. Return on investment will be considered when determining feasibility of implementing green features. 

Design elements will be prioritized based on their ability to provide future energy savings, water conservation, waste reduction, and improved indoor air quality. Key factors to consider incorporating into the design include:
1. Use of passive solar energy
2. Natural lighting (day lighting) and adjustable lighting systems
3. Highly reflective roof and
