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

U.S. Department of Energy - Loan Guarantee Program

Note: The Inflation Reduction Act (H.R. 5376) made several changes to this program. It appropriated approximately $11.7 billion in total for the Loan Programs Office (LPO) to support issuing new loans. This, in turn, increased the loan authority in LPO’s existing loan programs by approximately $100 billion. The Inflation Reduction Act also adds a new loan program, the Energy Infrastructure Reinvestment (EIR) Program (section 1706), to help retool, repower, repurpose, or replace energy infrastructure that has ceased operations or to improve the efficiency of infrastructure that is currently operating.

Energy Efficient State Building Initiative

In June 2008, the Governor of Indiana issued an Executive Order establishing an energy efficient state buildings initiative. The order requires the Indiana Department of Administration (DOA) to develop design standards for all new state buildings that require a cost-effectiveness analysis of the building with a goal of achieving energy efficiency. These rules apply to all state agencies, departments, boards, offices, commissions, and public universities. 

The DOA has incorporated the requirements of the Executive Order into Indiana's standard instructions to designers for projects on state-owned buildings. Efficiency can be demonstrated through adherence to any of the following standards:
