AEP operates a developer portal exposing usage, billing, outage and account APIs, with OAuth 2.0 for customer-authorized access and API keys for B2B. Combined with Green Button Connect My Data, third parties such as Nectar (see docs.nectarclimate.com) can fetch authorized 15-minute interval and billing data. In Ohio, CRES providers also use EDI and the Business Partner Portal (a separate AEP Ohio operating company).
Available Appalachian Power API Endpoints

Rate Schedules & Tariff Analysis
Appalachian Power Virginia C&I bills separate generation and distribution components and, for demand-metered schedules, add a per-kW demand charge on top of per-kWh energy, plus fuel and statutory riders (RPS/RAC). Demand charges drive the largest share of larger customers' bills, so peak management and load factor matter most. Time-of-use options reward off-peak shifting. Exact values are set by the Virginia SCC in Tariff No. 28; multi-state customers should note WV and TN have separate tariffs.
Appalachian Power Rate Schedule List
| Schedule | Applicability |
|---|---|
| Small General Service (SGS) | Smaller commercial (VA). |
| Large General Service (LGS) | Larger demand-metered commercial. |
| Large Power / Industrial Service | Large industrial / high-demand. |
| General Service Time-of-Use (rider) | Commercial TOU. |

Limitations & Considerations
- ⚠Data access and competitive-supplier rules vary significantly by state (VA, WV, TN, plus AEP Ohio CRES).
- ⚠EDI for competitive suppliers is available in Ohio but not currently in Virginia (manual enrollment).
- ⚠No direct CSV/XML billing export from the web portal (use Green Button XML for usage).
- ⚠Historical interval data beyond ~6 weeks requires a request and a VA fee (~$50 per 12-month history).
- ⚠Business Partner Portal and CRES EDI data access apply to AEP Ohio, not Virginia/WV/TN.
Appalachian Power Data Access FAQ
How does a business get 15-minute interval data from Appalachian Power?▾
Log in at the customer portal and use the energy usage dashboard (about six weeks of 15-minute data) or download Green Button ESPI XML. For longer history, request up to 12 months via provider/customer support (Virginia charges roughly $50 per 12-month history). Third-party apps can use Green Button Connect or the AEP developer API with customer authorization.
Does Appalachian Power support Green Button and a developer API?▾
Yes. APCo supports Green Button Download My Data (ESPI XML) for AMI customers and Connect My Data (OAuth 2.0) in supported states. AEP also runs a developer portal at developer.aep.com with usage, billing and AMI APIs using OAuth 2.0 / API keys.
How does a consultant or aggregator access a customer's APCo data?▾
Either the customer authorizes a Green Button Connect / developer-portal app via OAuth 2.0, or the consultant submits the AEP Customer Letter of Authorization to inforelease@aep.com (processed in ~5-10 business days) to receive billing and usage data directly. Platforms such as Nectar (docs.nectarclimate.com) use these standardized paths to retrieve billing and interval data with customer authorization.
What C&I rate schedules does Appalachian Power offer in Virginia?▾
Virginia non-residential service (S.C.C. Tariff No. 28) includes Small General Service (SGS) for smaller commercial loads and Large General Service / large power schedules for demand-metered commercial and industrial customers, plus optional time-of-use riders. Larger schedules bill a per-kW demand charge plus per-kWh energy. Exact rates are set by the Virginia SCC; see the tariff book.
Why do Appalachian Power rates and data rules differ by state?▾
APCo serves Virginia, West Virginia and Tennessee under separate state commissions, and AEP's Ohio operations are a distinct competitive market. Each jurisdiction has its own tariffs, fuel adjustments and supplier-choice rules, so demand charges, EDI availability and choice programs differ. Virginia rates are governed by S.C.C. Tariff No. 28.
