AEP Ohio Solar Overview
AEP Ohio (American Electric Power) is a major utility serving central and southern Ohio, including Columbus. A critical fact many homeowners don't realize: AEP Ohio uses net billing, not traditional net metering. This is a significant difference that affects your solar ROI.
Customers: 1.5 million
Net metering: NO - Uses net billing instead
Export rate: ~$0.04-0.06/kWh (generation only)
Solar rating: ⭐⭐⭐ Average (Source: utility tariff filings and DSIRE Database)
The net billing system means your excess solar exports are credited at a lower rate than you pay for electricity. Understanding this is essential for making informed solar decisions in AEP territory.
Net Billing vs Net Metering
This distinction is critical and often misunderstood:
| Feature | True Net Metering | AEP Ohio Net Billing |
|---|---|---|
| Export credit rate | Full retail (~$0.12-0.15/kWh) | Generation only (~$0.04-0.06/kWh) |
| Credit type | kWh bank (1:1) | Dollar credits (lower rate) |
| Best sizing | 100% of usage | Match daytime usage |
| Export value | High (same as purchase) | Low (~30-40% of retail) |
| Battery value | Lower | Higher (store vs export cheap) |
How AEP Net Billing Actually Works
- Solar generates: Your panels produce electricity
- Self-consumption first: Home uses what it needs
- Excess exports: Extra power goes to grid
- Credit at generation rate: ~$0.04-0.06/kWh (NOT retail)
- Credits roll forward: As dollar amounts on your bill
- Credits lost if you leave: Not paid out
Export Compensation
Current AEP Ohio Export Rates
- Export credit: Generation component only (~$0.04-0.06/kWh)
- Not included: Transmission, distribution, riders
- Result: ~30-40% of what you pay per kWh
The Math That Matters
| Scenario | Rate | Value of 1,000 kWh |
|---|---|---|
| Self-consumption (avoided purchase) | ~$0.14/kWh | $140 |
| Export to AEP | ~$0.05/kWh | $50 |
| Difference | -$0.09/kWh | -$90 lost value |
Potential Policy Changes
AEP Ohio has proposed further reductions to solar compensation at the Public Utilities Commission of Ohio (PUCO). While decisions are pending, this underscores the importance of going solar sooner rather than later if you're considering it.
AEP Ohio Electric Rates
Current Rate Structure
| Component | Rate | Notes |
|---|---|---|
| Generation | ~$0.04-0.06/kWh | This is your export credit rate |
| Transmission | ~$0.02-0.03/kWh | Not credited for exports |
| Distribution | ~$0.04-0.05/kWh | Not credited for exports |
| Riders/Other | ~$0.02-0.03/kWh | Various charges |
| Total | ~$0.13-0.16/kWh | What you pay |
Ohio's Competitive Market
Ohio has a deregulated electricity market. You can choose your generation supplier while AEP handles distribution. Your export credits are based on your supplier's generation rate, which varies.
Interconnection Process
AEP Ohio Interconnection Timeline
| Step | Timeline | Notes |
|---|---|---|
| Application | Day 1 | Installer submits to AEP |
| AEP review | 15-30 days | Technical review |
| Approval | 5-10 days | Authorization issued |
| Installation | 1-3 days | Physical install |
| Local inspection | 5-15 days | City/county inspection |
| AEP final | 10-20 days | Meter and final approval |
| PTO | 3-7 days | Permission to Operate |
Total timeline: 45-75 days typical. AEP's process can be slower during high-volume periods.
Making Solar Work with AEP
Strategy 1: Size for Self-Consumption
- Analyze hourly usage: Match solar to daytime loads
- Don't over-size: Excess exports have low value
- Typical approach: 60-80% of annual usage, not 100%
- Consider future loads: EV, heat pump additions
Strategy 2: Shift Loads to Daytime
- Run appliances midday: Dishwasher, laundry, etc.
- Program AC: Pre-cool during solar hours
- EV charging: Charge during solar production
- Pool pumps: Run during peak solar
Strategy 3: Add Battery Storage
- Store excess: Use evening instead of exporting cheap
- Backup power: Ohio has severe weather
- Math works: Battery more valuable without net metering
- Payback improves: When export rates are low
Strategy 4: Consider PPA/Lease
- 30% Section 48E: Through 2027 for PPA/Lease
- Lower payments: Benefit passed to customer
- No upfront cost: Start saving immediately
- Professional management: System optimized
Tips for AEP Ohio Customers
Do This:
- Get your hourly data: Analyze actual daytime usage
- Size conservatively: Match daytime usage, not total
- Calculate realistic ROI: Using actual export rates
- Consider batteries: More valuable with net billing
- Act before policy changes: PUCO decisions pending
Watch Out For:
- Installers assuming net metering: Verify they understand AEP
- Over-sized proposals: Exports have low value
- Inflated savings projections: Must use net billing math
- Ignoring self-consumption: Critical for AEP territory
Frequently Asked Questions
Does AEP Ohio have net metering?
No. AEP Ohio uses net billing, not traditional net metering. Exports are credited at the generation component only (~$0.04-0.06/kWh), not the full retail rate (~$0.14/kWh).
What is the difference between net metering and net billing?
Net metering gives you 1:1 kWh credits at retail rate—like the meter running backward. Net billing gives you monetary credits at a lower rate (generation only). AEP Ohio uses net billing, meaning exports are worth ~30-40% of retail.
Is solar worth it with AEP Ohio?
It can be, with the right approach. Focus on self-consumption (using the power you generate), don't over-size your system, and consider battery storage. Payback is longer than net metering states but still achievable.
How much does AEP pay for excess solar?
AEP Ohio credits exports at the generation rate only—approximately $0.04-0.06 per kWh. This is much lower than the ~$0.14/kWh you pay for electricity.
Should I get batteries with AEP Ohio?
Batteries make more financial sense with AEP than with true net metering utilities. Instead of exporting for $0.05/kWh and buying back for $0.14/kWh, you can store and use your own power at full retail value.
What size solar system should I get with AEP?
Size for daytime self-consumption, not 100% of usage. A detailed analysis of your hourly usage patterns is essential. Typically 60-80% of annual usage is optimal, depending on your daytime consumption.
