Why solar in Edmond

OG&E runs an annual true-up, typically in April, at which any remaining excess credits are compensated at its avoided cost rate rather than the retail rate. That single date is the point at which a year of accumulated surplus is converted from something worth around 13.4 cents per kWh into something worth 3 to 5. Knowing when it falls, and designing so that little is left to convert, is the practical response.

What happens at the annual true-up

OG&E nets generation against consumption within each billing period at the retail rate, and carries excess forward. At an annual true-up, typically in April, any remaining excess credits are compensated at the utility avoided cost rate.

Avoided cost has run in the region of 3 to 5 cents per kWh against an Oklahoma residential average around 13.4, so the conversion is roughly threefold downward.

April is a reasonable date for an Oklahoma household, falling after a winter that draws credits down and before the summer air conditioning season builds them back up.

It still means that any genuine annual surplus is converted at the low rate rather than banked. There is no rollover past the true-up at retail value.

Designing so there is little left to convert

The response is not to fear the true-up but to size so that very little reaches it. A system matched to your annual consumption should arrive at April with a small balance rather than a large one.

Ask for the monthly profile with the credit balance tracked through to the true-up date. That view shows directly how much of the system output is heading for the low rate.

A balance that climbs steadily through the year and arrives large at true-up describes an oversized system. One that rises and falls with the seasons and lands near zero describes a well-matched one.

Ask what percentage of your annual usage the design covers, and require a specific reason for anything meaningfully above 100 percent.

Confirming the details that matter

Ask OG&E to confirm the current true-up month, since a projection built on the wrong date will misjudge which months matter.

Ask what the current avoided cost rate is and how often it is reset. A figure from an older guide may not be the one applied at your true-up.

Ask whether the projection modelled the true-up at all. A model that carries credits forward indefinitely at retail value is describing something the tariff does not do.

Ask what proportion of projected savings comes from retail-rate offsetting rather than from true-up compensation. The first is the durable part; the second is small and rate-dependent.

Building the number without the federal credit

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 Edmond receives no federal tax credit, and Oklahoma 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 retail-rate offsetting within the billing period, carry-forward to an annual true-up, and avoided cost compensation for whatever remains at that point.

Ask for the monthly credit balance tracked through to the true-up date, with the true-up month and avoided cost rate confirmed by OG&E.

Net metering: Monthly netting at retail; surplus at avoided cost

The Oklahoma Corporation Commission requires investor-owned utilities, including OG&E and PSO, to offer net metering for solar systems up to 300 kW. The mechanism has two halves and they are worth separating. Within a billing period, your generation offsets your consumption at the retail rate, so midday production offsets evening usage in the same month before anything is treated as surplus. That is the valuable half, and it puts Oklahoma ahead of states like Georgia and Indiana that measure instantaneously. The second half is less favourable. The Commission rules do not require utilities to compensate genuine surplus at the full retail rate, and both major utilities credit excess beyond your usage at avoided cost, in the region of 3 to 5 cents per kWh against an Oklahoma residential average around 13.4 cents. PSO uses monthly netting with a twelve month carry-forward of excess credits, and OG&E runs an annual true-up, typically in April, at which remaining excess is compensated at avoided cost. The design conclusion follows directly and is unusually clean: build to your consumption and no further. A system matched to your annual usage captures the retail-rate offsetting almost entirely, while every kilowatt hour beyond that is worth roughly a third as much. Municipal utilities and rural electric cooperatives serve a substantial share of the state and set their own terms, so confirm which arrangement applies at your address.

Why solar + battery in Edmond

Oklahoma sits in a middle position on solar compensation, which is worth understanding precisely because it is neither the full retail credit some states still offer nor the instantaneous avoided-cost arrangement others have moved to. The Oklahoma Corporation Commission requires investor-owned utilities, including OG&E and PSO, to offer net metering for systems up to 300 kW. Within a billing period, generation offsets consumption at the retail rate. What the Commission rules do not require is full retail compensation for genuine surplus, and both major utilities credit excess beyond your usage at avoided cost, in the region of 3 to 5 cents per kWh against an Oklahoma residential average around 13.4 cents. The practical rule that follows is simple: build to your consumption and no further. Oklahoma has no state solar tax credit, and the federal residential credit expired for property placed in service after December 31, 2025.

Frequently asked questions

What happens to my excess credits with OG&E?

They carry forward and are compensated at the utility avoided cost rate at an annual true-up, typically in April. Avoided cost has run around 3 to 5 cents per kWh against a retail average near 13.4.

How should I design around the true-up?

So that very little reaches it. A system matched to your annual consumption should arrive at the true-up with a small balance. Ask for the monthly credit balance tracked through to that date.

How do I tell if my system is oversized?

A credit balance that climbs steadily through the year and arrives large at true-up describes an oversized system. One that rises and falls with the seasons and lands near zero is well matched.

What should I confirm with the utility?

The current true-up month and the current avoided cost rate, plus how often that rate is reset. Then ask whether the projection modelled the true-up at all, since a model carrying credits forward indefinitely at retail is wrong.
