Maryland’s net-metering law has been expanded several times since it was originally enacted in 1997. The net metering rules apply to all utilities -- investor-owned utilities (IOUs), electric cooperatives and municipal utilities. Residents, businesses, schools or government entities with systems that generate electricity using solar, wind, biomass, fuel cell, closed-conduit hydroelectric, and micro-CHP resources are eligible for net metering. The law permits outright ownership by the customer-generators as well as third-party ownership structures (e.g., leases and power purchase agreements). The provisions allowing for micro-CHP systems and certain third-party ownership structures were added in 2009. Net metering was extended to fuel

IID accepted applications for the 2015 PV Solutions Program from Jan. 3, 2015 – Jan. 31, 2015. Winners were determined via lottery. The program is now closed for the remainder of 2015, but another funding round is expected in 2016. 

Through the PV Solutions Rebate Program, Imperial Irrigation District (IID) provides rebates to its residential and commercial customers who install grid-tied photovoltaic systems. Systems less than 30 kilowatts (kW) can receive an upfront incentive based on the expected performance of the system. For 2015 the expected performance based incentive is $0.50 per watt, but may be reduced based on

Minnesota has several energy efficiency policies for state buildings, dating back to 2001. In April 2011, Governor Dayton signed a series of Executive Orders which created a comprehensive energy savings plan for state facilities. In addition to creating several new initiatives, the Orders also incorporated existing energy efficiency and renewable energy statutes and programs. inn April 2019, Governor Walz signed Executive Order 19-27 which updated existing guidelines for energy reduction and procurement.

Energy Reduction Requirements
Executive Order 11-12 set a goal of reducing energy use in state facilities by 20%. The Order does not set a deadline for reaching this

The Illinois Clean Energy Community Foundation (ICECF) was established in December 1999 as an independent foundation with a $225 million endowment provided by Commonwealth Edison. The ICECF invests in clean-energy development and land-preservation efforts, working with communities and citizens to improve environmental quality in Illinois. The ICECF provides competitive grants to programs and projects that improve energy efficiency, develop renewable energy resources, and preserve and enhance natural areas and wildlife habitats in Illinois.

Net Zero Energy Wastewater

Note: HB 589, signed in July 2017, requires the NCUC to adopt an expedited review process for swine and poultry waste energy projects of 2 MW or less. The NCUC issued an order in June 2019 with revisions to the interconnection standard including provisions for adding energy storage at existing solar PV sites, and expedited study of interconnection standard for small swine and poultry waste facilities. 

The North Carolina Utilities Commission (NCUC) first adopted comprehensive interconnection standards for distributed generation in 2005. The NCUC later updated the interconnection standards in 2008 and 2015. The current NCUC standards, which are similar

Note: As of February 2018, NC GreenPower has terminated the small solar generator program application.   

NC GreenPower, a statewide green power program designed to encourage the use of renewable energy in North Carolina, offers production payments for grid-tied electricity generated by solar, wind, small hydro (10 megawatts or less) and biomass resources. Payment arrangements for electricity generated by most renewable energy systems may be available by submitting proposals for consideration when NC GreenPower issues an RFP. However, owners of small wind energy systems (10 kW or less) may currently apply to receive program incentives at any time. Owners of

The City of Ukiah Electric Department is currently revising this program. Contact the department with any questions at (707)-467-5711.

Through Ukiah Utilities’ PV Buydown Program, residential and commercial customers are eligible for a $0.28-per-watt AC rebate on qualifying grid-connected PV systems up to a maximum system size of 1 MW. In keeping with SB1, the incentive level will decrease annually on July 1 over the 10 year life of the program. Rebates are available on a first come, first served basis and are limited to $7,000 per residential installation and $25,000 per commercial installation.

Hawaii law prohibits the creation of any covenant or restriction contained in any document restricting the installation or use of a solar energy system on a residential dwelling or townhouse. Furthermore, Hawaii requires homeowners associations to adopt rules that provide for the placement of solar energy systems and do not unreasonably restrict the placement. In July 2010, SB 2817 was enacted that clarified this requirement and required homeowners associations to pass rules by July 1, 2011 in accordance with this requirement. This legislation states that homeowners associations' rules and regulations cannot "render a solar energy device more than 25 per

Note: In April 2021, the Indiana Utility Regulatory Commission approved a proposal from CenterPoint South (formerly Vectren, Southern Indiana Gas & Electric Company) for a new distributed generation rate under the framework established by S.B. 309. The new rate uses a net billing system with instantaneous netting, with exported electricity compensated at 1.25* the locational marginal price (LMP) at CenterPoint's load node. As of March 2024, AES Indiana, Indiana Michigan Power, NIPSCO, and Duke Energy Indiana have filed updated tariffs with similar structures.

Note: Senate Bill 309, signed into law in May 2017, makes important changes to Indiana's compensation

The Florida Energy Conservation and Sustainable Buildings Act requires the use of energy-efficient equipment and design, and solar energy devices for heating and cooling state buildings where life-cycle cost analysis determines that solar-energy systems will be cost-effective over the life of the building. Florida law also requires that all new educational facilities include passive solar design. Florida mandates that schools with hot water demands exceeding 1,000 gallons per day must include a solar water heating system that provides at least 65% of hot water needs whenever economically feasible.

In June 2008, Florida enacted legislation (HB 7135) mandating that buildings constructed
