Rate Schedules & Tariff Analysis
CEI C&I rates separate regulated delivery (GS/GP/GSU under PUCO No. 13, driven by voltage level, demand kW, and riders) from the deregulated generation portion (SSO Price to Compare vs. a competitive supplier). Taking service at a higher voltage (GP or GSU) generally lowers per-unit distribution, and demand management lowers the kW component. The February 2026 PUCO order raised CEI distribution revenue by ~$48.7M effective March 1, 2026.
The Cleveland Electric Illuminating Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate GS | Commercial / small industrial (secondary voltage) |
| Rate GP | Larger C&I (primary voltage) |
| Rate GSU | Large industrial (subtransmission voltage) |

Limitations & Considerations
- ⚠Green Button / ESPI (Download My Data and Connect My Data) support for CEI is not clearly documented publicly; automated access relies on the SUMR portal and EDI instead.
- ⚠The Analyze Usage tool is primarily for viewing; bulk programmatic export requires the SUMR portal, manual request, or EDI.
- ⚠SUMR portal and EDI access are limited to PUCO-licensed suppliers and registered service providers with a customer LOA.
- ⚠Specific customer-charge and demand-charge dollar figures are published only in the PUCO No. 13 tariff and change with rate proceedings (e.g., the March 1, 2026 update).
- ⚠System-to-System Historical Interval Usage (StS HIU) is referenced but lacks detailed public technical specifications.
The Cleveland Electric Illuminating Company Data Access FAQ
Can my business choose its electricity supplier?▾
Yes. Ohio is a deregulated market under Energy Choice Ohio, so C&I customers can buy generation from any PUCO-certified competitive retail electric supplier while CEI continues regulated delivery. If you don't choose, you receive the Standard Service Offer at the Price to Compare. Compare offers at energychoice.ohio.gov.
How does my business access its 15-minute interval data?▾
First-party customers can view interval data in the Analyze Usage tool after logging in to My Account. For bulk or programmatic export, a registered supplier or service provider can pull 15-minute and hourly data through the SUMR portal with a customer Letter of Authorization, or via EDI.
How can a consultant or supplier get our usage data automatically?▾
If they are a PUCO-licensed supplier or registered service provider, they use the SUMR portal (with your LOA) or EDI 814HU/867HU after completing EDI testing with FirstEnergy. Non-registered consultants can use the Customer Information Authorization (CIA) form for manual billing-data requests.
What rate schedule is my business on?▾
CEI assigns C&I customers to Rate GS (secondary voltage), Rate GP (primary voltage), or Rate GSU (subtransmission voltage) under PUCO No. 13, based largely on the voltage at which you take service. Higher-voltage service (GP/GSU) generally carries lower per-unit distribution charges but requires suitable facilities.
Did CEI distribution rates change in 2026?▾
Yes. Following a February 2026 PUCO entry on rehearing, CEI filed updated distribution tariffs by February 24, 2026 effective March 1, 2026, raising its annual distribution revenue by about $48.7 million. PUCO also ordered roughly $245 million of deferred storm-restoration costs amortized over 25 years to limit bill impacts.
Does CEI support Green Button?▾
FirstEnergy's Green Button / ESPI Connect My Data status for CEI is not clearly documented publicly. For first-party data, use the Analyze Usage tool; for automated third-party access, use the SUMR portal or EDI. Contact Supplier Services (330-761-4348) to confirm any Connect My Data availability.
