Duke Energy Indiana, LLC Data Access FAQ
How does a C&I customer get 15-minute interval data from Duke Energy Indiana?▾
Business customers log in to the Business Experience portal, open the Energy Usage / Reports section, select 15-minute granularity and a date range, and export to CSV or Excel. You can also schedule recurring interval-data reports to be emailed automatically. There is no Green Button Connect or public API in Indiana.
How can I give an energy consultant access to my Duke Energy Indiana data?▾
Use portal User Management (Shared Access): the primary account holder invites the consultant by email, selects which accounts they can see, and sets permission level (usage only, usage + billing, or full). The consultant activates an account and downloads the authorized data. Alternatively, submit a signed authorization letter to Business Customer Service.
Is there a Green Button or developer API for Indiana?▾
No. Duke Energy Indiana has not implemented Green Button Connect My Data and offers no official developer API. The former Gateway pilot and community integrations were retired in June 2023. Programmatic access today is via portal exports and scheduled reports; third-party rate data is available through the kwcost API.
Can I shop for a competitive electricity supplier in Indiana?▾
No. Indiana is a regulated, vertically integrated market with no retail electric choice. Duke Energy Indiana is the sole distribution utility and retail supplier, and all rates are set by the IURC. C&I customers optimize cost through rate-schedule selection, demand management, demand response, and renewable programs rather than supplier shopping.
Which rate schedule applies to a large industrial facility?▾
Large facilities typically take Rate HLF (High Load Factor) service, while general commercial accounts use general-service/LLF schedules; very large loads may qualify for large-power schedules. The applicable schedule depends on load factor, demand, and voltage. Consult Duke's Indiana electric tariff and your account manager to confirm the optimal classification.
