Why solar in Columbus

Home batteries are usually sold on backup power, and in Columbus that is the weaker half of the argument. Under Georgia Power instantaneous netting, every kilowatt hour a battery lets you use in the evening instead of exporting at midday is converted from the Solar Avoided Cost Rate to the full retail rate. That is a real, recurring, quantifiable gain, and it is why the storage case is stronger in Georgia than in most of the country.

Why storage earns its keep under this tariff

Georgia Power nets generation against consumption instantaneously. Production above your instantaneous demand is exported at the annual Solar Avoided Cost Rate, 3.2188 cents per kWh for 2026 with a 4 cent adder approved in the 2022 rate case, against a residential retail rate in the region of 14 to 15 cents.

A battery captures midday production that would otherwise be exported and releases it in the evening when the house is drawing power. Each kilowatt hour moved that way is upgraded from the export rate to the retail rate.

In a retail-rate net metering state that arbitrage does not exist, because an exported kilowatt hour and a consumed one are worth the same. That is why national guidance treats home storage as a resilience purchase and why it undersells the case here.

The value is a function of how many kilowatt hours the battery can move each day and how many days a year it can do it, which is a calculable number rather than an impression. Ask for it as a number.

Sizing storage for arbitrage rather than for backup

A battery sized for arbitrage and one sized for backup are different products. The arbitrage question is how much surplus your system produces on a typical day and how much evening load you have to absorb it.

Oversizing storage is possible and wasteful. A battery larger than your daily surplus spends part of its capacity idle, earning nothing, while still costing what it cost.

Ask your installer for the daily profile: expected generation, expected household consumption and the resulting surplus, hour by hour on a typical summer day and a typical winter day. The right battery size falls out of that picture.

Ask what the model assumes about round-trip efficiency. A battery does not return everything you put into it, and a projection that ignores losses overstates the arbitrage gain.

Backup as the second benefit, specified properly

The resilience benefit is real and is worth having, but it needs specifying rather than assuming. Solar alone does not power a house during an outage: a standard grid-tied inverter disconnects when the grid goes down, for line worker safety.

Backup requires the battery plus the right inverter and switching arrangement, and it should appear in the quote as equipment. Ask which circuits would be backed up and for how long under a realistic load.

Note that backup and arbitrage pull against each other. Capacity reserved for an outage that may not come is capacity not being cycled for savings, so ask how the system is configured to balance the two.

That is a legitimate trade rather than a problem, but you should be the one making it. Ask what reserve level is set by default and whether you can change it.

Costing it out against a capped programme

The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase in Columbus receives no federal tax credit on the panels or the battery, and Georgia has no state solar tax credit.

Section 48E survives at 30 percent for third-party owners under leases and power purchase agreements, so ask what a provider claims and what reaches you in the rate.

What exists is the arbitrage the tariff creates: retail value for self-consumed electricity against avoided-cost value for exports, which is what the battery is monetising.

Ask for the projection with and without storage, with the daily surplus profile behind it, round-trip losses included, and the backup reserve stated. Those four things turn a battery from a promise into a calculation.

Net metering: Instantaneous netting at avoided cost (no net metering)

Georgia Power does not offer traditional net metering to new residential customers. Its programme, RNR-Instantaneous Netting, measures generation against household consumption at the instant it occurs. Electricity your home is drawing at that moment is offset at the full retail rate, because you simply do not buy it. Anything beyond your instantaneous demand is exported and credited at the annual Solar Avoided Cost Rate, 3.2188 cents per kWh for 2026, with a 4 cent per kWh adder approved in the 2022 rate case. Against a Georgia Power residential retail rate in the region of 14 to 15 cents, that means the same kilowatt hour is worth several times more consumed than exported. Nothing accumulates as a kilowatt hour bank to be drawn down later, so a sunny afternoon with nobody home is not stored value, it is a small credit. Two consequences follow. First, oversizing is penalised harder here than in almost any other state, and residential systems are capped at 10 kW AC in any case. Second, batteries and load shifting are worth more here than the national conversation suggests, because both convert low-value exports into high-value self-consumption. A separate monthly netting programme existed but was capped at 5,000 customers and filled in 2021, and is closed to new participants.

Why solar + battery in Columbus

Georgia does something with rooftop solar that almost no other state does, and it decides how a system here should be designed. Georgia Power does not offer traditional net metering. Its residential programme, RNR-Instantaneous Netting, nets your generation against your consumption instant by instant rather than across a month or a year, and anything your house is not using at that exact moment is exported and paid at the Solar Avoided Cost Rate, which was 3.2188 cents per kWh for 2026 with a 4 cent per kWh adder approved in the 2022 rate case. Against a Georgia Power residential retail rate in the region of 14 to 15 cents, that means a kilowatt hour you use yourself is worth several times one you export. Self-consumption is not a refinement here, it is the entire economic case. Georgia also has no state solar tax credit, and the 30 percent federal residential credit ended for property placed in service after December 31, 2025.

Frequently asked questions

Why is a battery more valuable in Georgia?

Because instantaneous netting pays a low avoided-cost rate for exports against a retail rate of roughly 14 to 15 cents. A battery moves midday surplus into evening use, upgrading each of those kilowatt hours from the export rate to the retail rate.

How big a battery do I need?

It depends on your daily surplus and your evening load, not on a standard size. Ask for the hourly profile of generation, consumption and surplus on a typical summer and winter day, and size to that. A battery larger than your daily surplus sits idle.

Does the projection account for battery losses?

It should. A battery does not return everything put into it, so ask what round-trip efficiency the model assumed. A projection that ignores losses overstates the arbitrage gain.

Can the battery do backup and savings at once?

Partly, and they pull against each other. Capacity held in reserve for an outage is capacity not being cycled for savings. Ask what reserve level is set by default, whether you can change it, and which circuits backup actually covers.
