Model Ordinance for Renewable Energy Projects

NOTE: This model ordinance was designed to provide guidance to local governments that wish to develop their own siting rules for renewable energy projects. While it was developed by the Oregon Department of Energy, the model itself has no legal or regulatory authority.

The Oregon Department of Energy issued guidance to local governments to address wind, solar, geothermal, biomass, and co-generation project planning needs at the city and county level in July 2005. The Model Ordinance describes energy projects and siting issues and includes model ordinance language and commentary. Energy projects below certain thresholds are not regulated by the Oregon Energy

Renewable Energy Renaissance Zones

In 2006, Michigan enacted legislation allowing for the creation of Renewable Energy Renaissance Zones (RERZ). Renaissance zones offer significant tax benefits to facilities located within their boundaries. Facilities within a renaissance zone do not pay the Michigan Business Tax*, state education tax, personal and real property taxes, or local income taxes (where applicable). These taxes may be abated for up to 15 years, with the abatements being phased out in 25% increments over the last three years of the zone designation. For residents of renaissance zones designated before 2012, taxpayers are exempt from paying certain income taxes, if they

Puerto Rico - Interconnection Standards

In 2007, the Autoridad de Energía Electrica de Puerto Rico (PREPA*) adopted interconnection standards based on the standard contained in the federal Energy Policy Act of 2005. PREPA promulgated interconnection rules in August 2008 that apply to all distributed generation (DG) projects that interconnect to PREPA’s electric distribution system. Interconnected systems must meet all safety and performance standards established by IEEE Standard 1547 as well as local construction and safety codes. A manual external disconnect switch is required for all interconnected systems.


Customer-generators seeking to interconnect first submit a standardized "Evaluation Request" to PREPA to determine whether or not the system

Renewable Energy Standard

Michigan enacted Public Act 235 in November 2023, expanding renewable energy requirements substantially and adding a clean energy standard. Renewable energy requirements are now 50% by 2030 and 60% by 2035. Clean energy requirements are 80% by 2035 and 100% by 2040.

In October 2008, Michigan enacted the Clean, Renewable, and Efficient Energy Act (Public Act 295), requiring the state's investor-owned utilities, alternative retail suppliers, electric cooperatives, and municipal electric utilities to generate 10% of their retail electricity sales from renewable energy resources by 2015. SB 438, signed in December 2016, increased this requirement to 15% by 2021, and

Net Billing

Note: In December 2016, the Arizona Corporation Commission (ACC) voted to replace net metering with "net billing", where new customer-generators will be credited at an avoided cost rate for energy exported to the grid. Although this entry is categorized as net metering, the policy adopted by the ACC does not meet DSIRE's definition of net metering, as excess generation will no longer be netted one-to-one against consumption over the billing period.

Eligibility and Availability

Net billing is available to investor-owned utility and electric cooperative customers who generate electricity using solar, wind, hydroelectric, geothermal, biomass, biogas, combined heat and power, or
