Power Purchase Agreements (PPAs) in Georgia

A Power Purchase Agreement (PPA) is a long-term solar financing arrangement that allows a property owner to host a solar energy system without purchasing the equipment outright. This page covers how PPAs are structured under Georgia's regulatory environment, the types of scenarios where they apply, and the practical boundaries that separate them from leases and direct purchases. Understanding these distinctions is essential for any property owner evaluating Solar Financing Options for Georgia Homeowners or comparing Solar Leasing vs. Purchasing in Georgia.


Definition and scope

A Power Purchase Agreement is a contractual arrangement in which a third-party solar developer owns, installs, operates, and maintains a photovoltaic system on a host property. The property owner does not purchase the equipment. Instead, the host agrees to buy the electricity generated by the system at a defined per-kilowatt-hour rate — typically set below the prevailing retail utility rate at contract inception — for a fixed term, commonly ranging from 15 to 25 years.

PPAs are distinct from solar leases in a critical way: under a lease, the host pays a fixed monthly amount regardless of how much electricity the system produces. Under a PPA, the host pays only for actual kilowatt-hours delivered. This production-linked payment structure shifts weather and performance risk differently between the two instruments.

PPAs are governed in Georgia by contract law under the Official Code of Georgia Annotated (O.C.G.A.), and any solar system connected to the grid must comply with interconnection requirements administered by the Georgia Public Service Commission (GPSC) and the applicable electric utility — primarily Georgia Power under its tariffs on file with the GPSC, or one of Georgia's 41 Electric Membership Corporations (EMCs).

Scope and coverage limitations: This page addresses PPAs as they apply to properties located within the state of Georgia. Federal tax treatment — including the 30% Investment Tax Credit (ITC) under 26 U.S.C. § 48, which in a PPA flows to the system owner, not the host — is governed by the Internal Revenue Code and falls outside Georgia-specific regulatory authority. Commercial PPA structures involving securities law considerations are regulated by the U.S. Securities and Exchange Commission and the Georgia Secretary of State, Securities Division, not by this reference. Agricultural and utility-scale PPAs may involve additional federal permitting outside this page's scope.


How it works

A residential or commercial PPA in Georgia proceeds through a defined sequence of phases:

  1. Site assessment: The solar developer evaluates roof condition, shading, orientation, and annual solar resource. Georgia's climate averages approximately 5.0 peak sun hours per day in Atlanta-metro areas (National Renewable Energy Laboratory, PVWatts), shaping production projections that anchor the per-kWh rate.
  2. Contract negotiation: The PPA term, starting rate, annual escalator (if any), and end-of-term options (buyout, renewal, or removal) are fixed in writing. Escalators in Georgia PPAs historically range between 0% and 3% per year, though the contract language controls — no state-mandated cap exists.
  3. Permitting and inspection: The developer, as system owner, is responsible for obtaining all local building permits and electrical permits. Georgia does not have a statewide unified solar permit, so requirements vary by county and municipality. The Georgia State Minimum Standard Codes — including adoption of the National Electrical Code (NEC) — apply to all installations. For a detailed breakdown, see Permitting and Inspection Concepts for Georgia Solar Energy Systems.
  4. Installation: The developer's contractor installs the system. Georgia requires electrical contractors to hold licensure through the Georgia Secretary of State, Professional Licensing Boards Division. See Georgia Solar Installer Licensing Requirements for the specific credential framework.
  5. Utility interconnection: The developer submits interconnection applications to Georgia Power or the relevant EMC under the utility's tariff-approved process, coordinated under GPSC oversight. Details appear in Georgia Utility Interconnection Requirements.
  6. System activation and billing: Once the utility issues permission to operate, the host begins receiving solar electricity and monthly invoices based on metered production at the contracted rate.
  7. End-of-term disposition: At contract expiration, the host typically has three options: purchase the system at fair market value, extend the agreement, or have the developer remove the equipment at no cost.

Common scenarios

Residential PPAs are most common on owner-occupied homes where the owner lacks capital or prefers not to finance a purchase, but wants immediate bill reduction without upfront cost. The federal ITC — 30% of system cost under the Inflation Reduction Act of 2022 (26 U.S.C. § 48E) — is claimed by the developer, not the homeowner, in this structure.

Commercial and industrial PPAs are used by businesses, nonprofits, and municipalities seeking to offset operating costs. Nonprofit entities that cannot monetize tax credits directly often find PPAs advantageous because the developer captures the ITC and can price electricity lower as a result.

Community solar PPAs are an emerging variant in Georgia, where subscribers purchase shares of output from a remote array. Community Solar Programs in Georgia covers the subscriber-model distinctions specific to Georgia utility programs.

Agricultural PPAs on Georgia farmland — including agrivoltaic configurations — can overlap with USDA Rural Energy for America Program (REAP) grant considerations and require separate analysis. See Agricultural Solar Energy Systems in Georgia for context.

Georgia Power's specific solar buyback and net metering policies directly affect PPA economics. The Georgia Net Metering Policy Explained page documents how excess generation is credited, and the Georgia Power Solar Buyback Program page addresses tariff-specific terms that interact with PPA structures.


Decision boundaries

The following comparison clarifies when a PPA is structurally appropriate versus when alternative financing fits better:

Factor PPA Solar Loan / Purchase
Upfront cost $0 Varies ($0 for loan; full cost for cash)
ITC benefit recipient Developer System owner
Ownership of panels Developer Homeowner / business
Property sale complication Lease/PPA transfer or buyout required None — asset transfers with property
O&M responsibility Developer Owner
Long-term cost ceiling Escalator-linked Fixed at purchase
