Energy-Efficient Mortgages

Homeowners can take advantage of energy efficient mortgages (EEM) to either finance energy efficiency improvements to existing homes, including renewable energy technologies, or to increase their home buying power with the purchase of a new energy efficient home. The U.S. federal government supports these loans by insuring them through Federal Housing Authority (FHA) or Veterans Affairs (VA) programs. This allows borrowers who might otherwise be denied loans to pursue energy efficiency, and it secures lenders against loan default.

FHA Energy Efficient Mortgages
The FHA allows lenders to add up to 100% of energy efficiency improvements to an existing mortgage loan

Montana Commercial PACE Financing Program

Property-Assessed Clean Energy (PACE) financing effectively allows property owners to borrow money to pay for energy improvements. The amount borrowed is typically repaid via a special assessment on the property over a period of years. In 2021, S.B. 147 authorized the creation of a Commercial PACE (C-PACE) program to be administered by the Montana Facility Finance Authority (MFFA). To be eligible, properties must be located in a Montana city, county, town, or a consolidated city-town that has or will establish a C-PACE District. C-PACE District designation is tracked by the MFFA and may be viewed here.

Interconnection Standards

Alabama does not have statewide interconnection standards. 

Southern Company, the parent company of Alabama Power Company, does have a policy on operation of distributed energy resources (DER) in parallel with the distribution system. 

The policy does not give explicit information on system size limits in relation to levels of review. The scope of any required system impact study is determined jointly by the DER owner and the utility. Following the system impact study, an interconnection equipment study may also be required. Incorporation of energy storage systems may require additional study.

NY Open C-PACE

Note: In 2010, the Federal Housing Finance Agency (FHFA), which has authority over mortgage underwriters Fannie Mae and Freddie Mac, directed these enterprises against purchasing mortgages of homes with a PACE lien due to its senior status above a mortgage. Most residential PACE activity subsided following this directive; however, some residential PACE programs are now operating with loan loss reserve funds, appropriate disclosures, or other protections meant to address FHFA's concerns. Commercial PACE programs were not directly affected by FHFA’s actions, as Fannie Mae and Freddie Mac do not underwrite commercial mortgages.

Marin Clean Energy - Feed-In Tariff Plus

Marin Clean Energy (MCE), a Community Choice Aggregator, provides an incentive for its customers to install renewable energy systems through the Feed-In Tariff (FIT) Plus Program. MCE will pay for all energy, environmental attributes, capacity, and if applicable, storage-related services and attributes delivered by the system at a fixed rate based on metered energy quantities multiplied by the applicable contract price for the delivery term.

The contract price is scheduled to step down over time as the installed capacity of all participating systems increases.  As of May 2024 there are 10.8 MW remaining on the 5th of 6 steps
