Clean Energy Alliance Data Access Guide
Clean Energy Alliance (CEA) is a Community Choice Aggregator (CCA) serving roughly 209,000 electric customers across seven North County San Diego cities. CEA procures clean power and sets generation rates, while San Diego Gas & Electric (SDG&E) handles delivery, metering, billing, and all data access — so CEA customers use SDG&E's My Energy Center portal, Green Button, and Share My Data infrastructure.

See the Clean Energy Alliance Rate Schedules & Tariff Guide →Interval Data & Smart Meters
SDG&E has near-100% AMI coverage, so CEA customers have smart meters recording interval data. Business/commercial customers get 15-minute intervals; residential customers get 60-minute (hourly) intervals. Interval data is downloaded via Green Button Download My Data in My Energy Center, or shared automatically via Green Button Connect My Data / UtilityAPI.
How to Download Clean Energy Alliance Interval Data via Green Button
- 01Log in to https://www.myenergycenter.com/
- 02Open the Usage tab and select the Electric meter
- 03Scroll below the consumption graph to the Green Button Download button
- 04Select the date range (up to 13 months) and XML format, then download the ESPI file
Interval data is essential for rate comparison and TOU analysis.

Third-party access to CEA customer data runs entirely through SDG&E's infrastructure. Registered developers use SDG&E's Green Button Connect My Data RESTful API (ESPI/OAuth 2.0) to retrieve authorized interval data, or use the UtilityAPI aggregator platform, which handles SDG&E authorization and delivers CSV/XML/JSON with full history.
Available Clean Energy Alliance API Endpoints
| Function | Endpoint | Method | Format |
|---|---|---|---|
| Retrieve interval usage (ESPI) | SDG&E Green Button Connect RESTful API (ESPI) | GET | XML (Atom) / JSON |

Rate Schedules & Tariff Analysis
A CEA commercial bill has two layers: SDG&E delivery (set by SDG&E/CPUC under the applicable schedule such as AL-TOU) and CEA generation (set annually by the CEA Board for the chosen product). The delivery layer carries the time-of-use energy and demand charges that drive most optimization opportunities; the generation layer is where CEA competes with SDG&E on price and clean content. For 2026, CEA's non-residential rate-relief credit of $0.02657/kWh narrows the generation cost vs SDG&E. Demand charges and TOU period management (on the SDG&E delivery side) remain the highest-impact C&I cost levers.
Clean Energy Alliance Rate Schedule List
| Schedule | Applicability |
|---|---|
| CEA Clean Impact (generation) | Default generation product |
| CEA Clean Impact Plus | Clean-content opt-up |
| CEA Green Impact | 100% renewable opt-up |
| SDG&E AL-TOU (delivery) | C&I delivery ≥ 20 kW |
Clean Energy Alliance Rate Features & TOU Details
- Two-layer bill: SDG&E delivery + CEA generation
- Time-of-use periods and demand charges live on the SDG&E delivery schedule
- CEA generation rate depends on product (Clean Impact / Plus / Green Impact)
- 2026 non-residential rate-relief credit of $0.02657/kWh (verified)
- No fixed contracts — customers can change products or opt out anytime

CEA Generation Products (Clean Impact / Clean Impact Plus / Green Impact)
CEA's CCA model auto-enrolls customers in the default Clean Impact product. Customers can opt up to Clean Impact Plus or 100% renewable Green Impact, or opt down/out to SDG&E generation. The product chosen sets the CEA generation rate that appears on the SDG&E bill.

- 02Opt up to Clean Impact Plus or Green Impact, or opt down/out, online or by calling (833) 232-3110
- 03The selected generation rate appears as the CEA line item on the SDG&E combined bill
Privacy GreenLight Program (SDG&E)

- 01Review program eligibility on the CEA website
- 02Engage CEA/Luminia for a solar-plus-storage assessment
- 03Enroll qualifying facilities
Limitations & Considerations
- ⚠CEA operates no metering, billing, or data API of its own — all data access flows through SDG&E.
- ⚠Green Button interval history is limited to 13 months (billing history is 25 months); full history requires UtilityAPI.
- ⚠CEA controls only the generation rate; SDG&E delivery charges and rate-schedule selection (e.g., AL-TOU) are outside CEA's control.
- ⚠Becoming a registered SDG&E Green Button developer requires substantial security vetting (NIST 800-53).
- ⚠True real-time streaming is not available — data is 15-minute/hourly historical.
- ⚠CEA does not run its own branded Share My Data program (unlike some CCAs); it relies on SDG&E Green Button and Privacy GreenLight.
Clean Energy Alliance Data Access FAQ
How do CEA commercial customers access their interval data?▾
Through SDG&E, the metering utility. Business customers get 15-minute interval data via Green Button Download My Data in My Energy Center (up to 13 months, ESPI XML), via Green Button Connect My Data for automated OAuth sharing to approved apps, or via UtilityAPI for full-history CSV/JSON. CEA does not operate its own meters or data API — all data flows through SDG&E.
How is a CEA bill structured for a business?▾
CEA customers get a single combined SDG&E bill. SDG&E delivery (distribution, transmission, and most fixed charges) is billed under the SDG&E rate schedule (e.g., AL-TOU for ≥20 kW), while CEA's generation charge replaces SDG&E's generation line. The CEA generation rate depends on the chosen product — Clean Impact (default), Clean Impact Plus, or Green Impact.
Is CEA more expensive than SDG&E for commercial customers?▾
CEA sets its generation rates with the goal of matching or beating SDG&E. For 2026, CEA approved rate-relief credits that include a non-residential credit of $0.02657 per kWh (verified, in effect through Dec. 31, 2026) to achieve rate parity with SDG&E for the Clean Impact product. The annual Joint Rate Comparison (currently effective for 4/1/26 rates) shows the side-by-side comparison; confirm current generation rates in CEA's adopted commercial rate schedule.
How does a consultant or aggregator get authorized for CEA data?▾
Because data lives with SDG&E, third parties register as SDG&E Green Button Connect developers (OAuth 2.0; ~2-4 week approval) or use UtilityAPI, which handles SDG&E authorization. For aggregated/anonymized research data, eligible organizations use SDG&E's Privacy GreenLight program. Individual customers authorize via My Energy Center and can revoke access anytime.
Can a business opt out of CEA and stay with SDG&E?▾
Yes. As a CCA, CEA auto-enrolls eligible customers in its default Clean Impact product, but any customer can opt out to SDG&E bundled generation, or opt up to Clean Impact Plus or 100% renewable Green Impact. The only generation choice is CEA versus SDG&E (plus CEA's product tiers) — there is no unregulated competitive retail supplier in this territory.
Does CEA support EDI for automated billing and meter data?▾
Yes, through SDG&E. SDG&E supports ANSI X12 EDI including 810 (invoice), 820 (remittance), 814 (DASR/account maintenance), and 867 (meter data), with v3030/v4010 implementation guides. Large C&I customers and registered partners execute a Trading Partner Agreement with SDG&E and connect via VAN or direct SFTP.
