A Georgia Power solar interconnection can stall after the roof work is finished. The missing item may be a customer signature, an inverter listing, or a meter number that differs from the drawing. A passed local inspection does not resolve those utility records.
Direct answer. Georgia Power solar interconnection starts with a PowerClerk application before construction. Select the residential or commercial path and the correct energy program. Submit matching customer, equipment, one-line, and site-plan records. Georgia Power reviews the connection, the customer signs an agreement, and the authority having jurisdiction inspects the installation. Complete meter work and any required witness test. Wait for Georgia Power’s written permission to operate before parallel operation.
This guide is for installers, permit coordinators, and commercial project engineers in Georgia Power’s service territory. It reflects Georgia Power materials available September 26, 2026. It does not describe every Georgia utility. Confirm project-specific requirements with Georgia Power and a qualified local reviewer.
The national interconnection application rejection guide explains common submission faults. This page deals with Georgia Power’s own program choices and records.
Does Georgia Power solar interconnection apply to this project?
Check the electric bill before choosing a form. A Georgia address does not prove Georgia Power service. The bill identifies the account holder and service location that must match the application. If another utility serves the meter, use that utility’s process instead of Georgia Power’s PowerClerk path.
The utility’s installation and interconnection page separates residential from commercial and industrial applications. Those paths have different PowerClerk portals and technical summaries. A mixed-use property still needs a utility account and service classification check before the team selects a lane.
Start the project record with the current bill, service address, account number, meter number, and customer contact. Then identify existing generation, storage, or standby equipment. The proposed system cannot be reviewed in isolation if it shares service equipment with an existing resource.
The local authority having jurisdiction (AHJ) and Georgia Power perform different reviews. The AHJ checks its permit and inspection requirements. Georgia Power checks the proposed parallel connection under its utility documents. Neither approval substitutes for the other.
Which Georgia Power program fits the proposed system?
The first design decision is the operating program, not the module count. Georgia Power describes Renewable and Nonrenewable Resources (RNR), Energy Offset Only (EOO), and a separate Qualifying Facility (QF) path for eligible commercial projects. That choice determines the export transaction and the agreement the customer must review.
| Program | Main question | Export compensation | Critical design record |
|---|---|---|---|
| RNR | Does the system meet the current RNR-11 tariff and participation conditions? | Yes, under the applicable tariff method | Aggregate inverter AC nameplate and selected RNR agreement |
| EOO | Is the design intended to offset on-site load without an export payment? | No | Actual export behavior, controls, and utility review outcome |
| QF | Is a commercial project pursuing a separate qualifying-facility transaction? | Under a separate agreement, if accepted | QF eligibility and the utility’s required agreements |
The Georgia Power RNR-11 tariff, effective for January 2023 billing, defines residential renewable eligibility at no more than 10 kW AC. It defines commercial renewable eligibility at no more than 250 kW AC. For commercial resources above 100 kW AC through 250 kW AC, the tariff adds a preceding-year peak-demand test.
Use the current tariff and application instructions on the submission day. The RNR tariff distinguishes instantaneous netting from a legacy monthly-netting pilot. New applicants should not assume they can enter the older pilot or receive a full-retail credit. This article omits a fixed avoided-cost rate because the rate changes.
EOO needs careful wording. The residential summary describes an EOO facility that cannot push energy onto the system. Georgia Power’s newer public installation page says an EOO project may export if engineering review finds no limitation, without compensation. The commercial summary also allows case-specific controls. Treat the project-specific Georgia Power decision as controlling. Do not translate the label EOO into automatic permission to export or a universal zero-export drawing note.
For a commercial QF concept, the July 31, 2026 C&I interconnection summary points applicants to Georgia Power’s QF process and separate agreements. Do not force that transaction into a standard RNR or EOO submission.
How do residential and commercial applications differ?
Georgia Power’s two summaries describe distinct lanes. The residential lane centers on a customer PowerClerk record, a one-line, a site plan, equipment evidence, an agreement, local inspection, and utility closeout. The commercial lane may add a feasibility analysis, more protection detail, an impact study, and a different agreement.
| Decision point | Residential behind-the-meter solar | Commercial and industrial behind-the-meter solar |
|---|---|---|
| Main utility guide | Residential summary, revised August 15, 2025 | C&I summary, revised July 31, 2026 |
| Portal route | Residential PowerClerk path | Distributed C&I PowerClerk path |
| Initial package | Account, one-line, site plan, equipment specifications | Account, one-line, equipment specifications, site plan, program and facility data |
| Additional engineering | Utility may request changes or testing | Feasibility review and possible impact study or protection drawings |
| Agreement | Customer signs the applicable service and interconnection agreement | Agreement form depends on program, facility, and financing arrangement |
| Closeout | Local inspection, required witness test, meter work, written PTO | Local inspection report, utility testing, final documents, written PTO |
Georgia Power’s residential summary and C&I summary are guidance documents. Both direct applicants back to current tariffs, policies, and agreements. A team should save the version it used for its design decision and recheck the live page before filing.
This split matters on a small commercial roof. The customer may have a simple array but a complicated service, transformer, or billing arrangement. A residential checklist pasted into that application can omit the point of connection or facility-owned transformer detail Georgia Power expects.
What must match before PowerClerk submission?
Treat the application as a controlled design record. PowerClerk values, customer account, one-line diagram, site plan, and equipment data sheets should describe one facility. A technically sound drawing cannot cure a different inverter model entered in the portal. Compare the final files before the customer signs the utility agreement.
Use this reconciliation sheet before the customer signs anything:
| Record | Source of truth | Compare against | Stop if |
|---|---|---|---|
| Customer and service identity | Current Georgia Power bill or authorized account record | PowerClerk, title block, agreement | Name, address, account, or meter differs |
| Modules and direct-current capacity | Final module schedule | PowerClerk, one-line, site plan | Model, count, or DC total differs |
| Inverters and alternating-current capacity | Final inverter schedule and data sheets | RNR eligibility, PowerClerk, one-line | Model, quantity, or AC rating differs |
| Operating program | Customer’s selected RNR, EOO, or QF path | Portal, controls note, agreement | Export behavior conflicts with program |
| Connection points | Field-verified service and design | One-line, site plan, utility review | Meter, point of connection, or disconnect moves |
| Storage and backup | Battery and transfer equipment data sheets | Portal, one-line, control sequence | Backup mode or export control is missing |
| Final installed equipment | Field photos and inspection record | Approved utility package | An equipment swap is undocumented |
This table is a checking method, not a Georgia Power form. Assign one person to compare the records and log each exception. The checker should record the source document, owner, correction, and date. A silent portal edit can leave the signed drawing inconsistent.
Georgia Power’s rooftop FAQ lists customer, facility, one-line, panel, inverter, installer, and applicable inspection information for PowerClerk. Its residential summary adds a site plan and fuller one-line detail. Commercial applicants should follow the C&I summary and any project-specific utility request.
What belongs on the one-line and site plan?
The one-line shows how the generation equipment connects through the customer’s electrical system to Georgia Power’s meter. The site plan shows where the equipment and disconnects physically sit. These drawings answer different review questions and should agree.
Georgia Power’s residential summary, revised August 15, 2025, says its one-line must be digital, not hand drawn. It calls for customer identity, module and inverter details, AC and DC capacities, generation AC disconnects, meter and point of interconnection, and existing versus new equipment. The site plan locates equipment, disconnects, and the interconnection point.
The July 2026 C&I summary asks for more. Its one-line includes the point of connection (POC) within customer equipment and point of interconnection (POI) with the utility system. It also calls for facility-owned transformer details when present. Georgia Power can request further protection drawings after initial review.
| Drawing label | What the reviewer must identify | Common mismatch |
|---|---|---|
| POI | Utility meter and utility-side interconnection reference | Wrong meter or service shown |
| POC | Exact electrical connection in customer equipment | Line-side or load-side method differs from portal |
| AC disconnect | Type, visible-break detail, mounting place, and label | Site plan moves it from one-line location |
| Inverter | Manufacturer, model, count, AC nameplate | Substitution after application |
| Storage | Battery, gateway, transfer arrangement, control behavior | Backup mode missing from one-line |
| Transformer | Facility-owned rating and winding configuration, if present | Existing transformer omitted |
For a commercial facility above 100 kW, the C&I summary says Georgia Power requires a professional engineer’s stamp on all drawings. That is a utility document requirement, not a statement that Heaven Designs holds a Georgia PE license or supplies stamping. The responsible project team must arrange the applicable professional review and confirm the current utility requirement.
The design team should keep the solar permit package checklist separate from this utility sheet. The single-line diagram guide explains drawing content, while Georgia Power’s current documents decide its submission format.
When does a commercial project need more utility study?
The July 2026 C&I summary says every facility at or above 250 kW undergoes an impact study. Smaller facilities may need one for safety, reliability, or aggregate circuit capacity. The utility decides from the actual feeder and proposed connection.
Do not treat a capacity threshold as a promised approval path. The C&I summary describes feasibility analysis, utility feedback, possible system upgrades, and an impact study where applicable. It advises customers not to purchase equipment before Georgia Power reviews how the facility integrates with existing service.
Three commercial records are easy to confuse:
- RNR eligibility. The current RNR-11 tariff sets its commercial AC nameplate limit and peak-demand condition.
- Drawing responsibility. The C&I summary states the drawing stamp requirement for facilities above 100 kW.
- Impact study. The C&I summary sets a 250 kW study trigger and permits study below it when needed.
These are different decisions. Passing one does not resolve the others. A 120 kW proposed array, for example, still needs the demand-limit and drawing-responsibility questions answered. Whether it needs a study depends on Georgia Power’s review. The example is a routing illustration, not an approval claim.
For three-phase commercial work, the three-phase interconnection guide explains service and protection questions that arise before a utility-specific filing. Georgia Power remains the source for its own application and testing requirements.
What changes when the project includes a battery?
Battery storage changes the operating description, not just the equipment list. The application should state whether the battery operates in parallel with the grid, supplies backup loads, charges from the grid, or can export. The one-line and control notes need to support that description.
Georgia Power’s residential summary asks for battery specifications and, for applicable backup-capable storage, its non-export application form. It identifies UL 1741 SB and IEEE 1547-2018 listing evidence for inverter equipment. The C&I summary discusses parallel and standby modes, open-transition transfer equipment, and project-specific controls. Read the current documents for the selected lane before finalizing a battery design.
The IEEE 1547 glossary entry explains the interconnection standard. The UL 1741 SB entry explains the equipment certification context. Neither glossary page replaces the current Georgia Power policy or a product’s actual listing sheet.
A battery marketed as “backup” does not tell the utility how it behaves at the service connection. Show the transfer path, isolation device, and operating modes on the drawing. If the equipment can perform a mode not intended for this project, document how the selected configuration prevents it.
In what order do agreement, construction, and inspection occur?
Georgia Power recommends submitting early, before construction or equipment purchase. Its published residential and C&I summaries place utility review and the applicable agreement ahead of installation. The C&I lane can involve additional studies and upgrades before a build can proceed.
The order is worth writing on the project schedule:
- Confirm the Georgia Power account, program, and proposed operating mode.
- Submit the proper PowerClerk application and technical records.
- Resolve Georgia Power review comments and any required study.
- Execute the applicable utility agreement.
- Install the approved facility and obtain local AHJ inspection evidence.
- Supply completion records and prepare for utility meter or witness work.
- Receive Georgia Power’s written Permission to Operate (PTO).
The live Georgia Power process page shows these milestones. Its website summary is helpful, but the applicable agreement and current utility instructions govern a real job. Do not infer a fixed completion time from the sequence.
Keep the AHJ inspection record tied to the same address and installed equipment shown in PowerClerk. The C&I summary calls for a final electrical inspection report, with the AHJ and permit number when applicable. A passed permit inspection proves a local milestone. It does not itself authorize parallel utility operation.
What happens at witness testing, metering, and PTO?
Georgia Power checks the final facility before authorizing parallel operation. The specific witness test and meter work depend on the project. Its residential summary says a required witness test must pass before operation. The C&I summary describes utility testing and a final emailed PTO letter after documents are complete.
The rooftop FAQ says the customer and installer receive an official PTO email when the project is complete. It also describes bidirectional meter programming where applicable. An installer should keep the written PTO, executed agreement, inspection report, test record, and final drawings together.
Do not use “inspection passed” as a substitute for PTO in customer communication. The two events come from different authorities. A utility-side meter appointment is also not the same as permission unless Georgia Power issues the required notice.
If Georgia Power returns a test or document correction, compare it with the approved design before changing field settings. A fix to one component can change export behavior or listing evidence elsewhere in the package. The AHJ comment response letter guide covers disciplined responses to permit comments, but utility comments still need the utility’s specified closeout path.
What if equipment changes after approval or PTO?
Treat every equipment change as a controlled design delta. Compare the replacement model, AC and DC ratings, listing, disconnect arrangement, operating mode, and point of connection with the approved PowerClerk record. Then ask Georgia Power which amendment or new filing it requires.
Georgia Power’s rooftop FAQ states that changes in ownership or system modifications after PTO require a new application. Its wording also ties PTO to the original customer account, equipment, AC capacity, interconnection point, and program. Recheck this guidance before a post-PTO expansion or transfer.
Before PTO, a field substitution still needs review. A replacement inverter with similar advertised power can have a different nameplate, listing, or control behavior. The job may need revised drawings, data sheets, and utility review even when the AHJ has already accepted the permit change.
For a broader revision record, see the equipment-swap and PE revision guide. Georgia Power’s instructions control the utility filing; a professional responsible for the drawings controls any required design revision.
How can Heaven Designs support the design package?
The expensive handoff is usually between sales layout, permit drawing, and utility application. One team may update the inverter schedule while another submits an older one-line. A single reconciliation owner can catch that before signatures or construction. Keep the exception log with the drawing revision record so the change remains visible.
Heaven Designs provides solar design and engineering support. For a Georgia Power project, the useful scope may include a plan set, one-line, site plan, equipment schedule, or revised drawing package. The serving utility, AHJ, and responsible licensed professionals still make their own decisions.
- Solar Permit Design covers AHJ-facing plan-set preparation.
- Solar Post-Design covers detailed engineering and execution drawings.
- Civil and Structural Engineering supports site-specific structural design when required.
Send the current bill, project location, service information, proposed equipment, and Georgia Power comments through the project contact form. The team can discuss a defined drawing scope. No utility approval, PE stamping arrangement, fee, or turnaround is promised here.
Frequently asked questions
Can a customer install before Georgia Power reviews the application?
Georgia Power recommends applying early and advises against purchasing equipment or starting construction before it reviews integration with the existing service. A local permit is a separate approval. For a live project, follow the current PowerClerk instruction and written utility response rather than assuming a completed permit settles interconnection.
Is 10 kW the limit for every Georgia Power solar system?
No. The RNR-11 tariff sets 10 kW AC as the residential RNR renewable-resource eligibility limit. Georgia Power also describes EOO, with a different program purpose and no export compensation. Capacity alone does not decide whether a particular design can connect. The utility reviews the service, equipment, and operating mode.
Does EOO mean the system can export without restriction?
No. EOO means the customer does not receive payment for exported energy. Georgia Power’s public documents use different wording about whether export may occur under EOO. Its engineering review may call for controls or a non-export configuration. Put the proposed behavior on the one-line and obtain a project-specific answer.
Does a passed local inspection authorize operation?
No. The AHJ inspection and Georgia Power’s PTO are separate milestones. Georgia Power’s current guidance requires final utility documents and applicable meter or witness work before its emailed PTO. Keep the written notice with the final inspection and agreement records.
Where does a commercial applicant submit?
Georgia Power’s installation page links a dedicated commercial and industrial PowerClerk portal. Use the account and service classification to select the lane. The July 2026 C&I summary lists its application evidence, possible study, agreement, inspection, and testing steps. Confirm the current portal link on the utility page rather than copying a saved login URL.
Do drawings always need a Georgia PE stamp?
The July 2026 C&I summary says drawings for a facility above 100 kW require a professional engineer’s stamp. That sentence does not establish the rule for every residential or smaller commercial project. The AHJ, Georgia Power, and responsible professional should confirm the exact project requirement and current document version.
The practical finish line is a matching record set and a written PTO. Keep the approved drawings, portal values, installed equipment, inspection result, and utility notice together. That file helps the next service technician understand what was actually authorized.
