The state framework sets the default. Where NIPSCO pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Excess distributed generation (EDG) is credited on the customer's monthly bill at the supplier's average marginal electricity price multiplied by 1.25; this replaced retail-rate net metering for new customers after the statutory transition. |
|---|---|
| Export rate | Utility-specific EDG rates, not one statewide rate; the verified utility-by-utility rates are listed in the utilities array below. |
| Rate effective | Rates are utility-specific and updated annually: AES Indiana's cited tariff is effective July 27, 2026; I&M's 2026 compliance filing applies with the March 2026 billing cycle; NIPSCO's latest located filing applies April 2025 through March 2026; Duke's cited initial rate was approved July 6, 2022. |
| Credit rollover | Yes. Excess bill credit is carried forward and applied against future charges while the customer continues receiving service at the premises. |
| Credit expiration | Credits continue while the customer receives electric service at the premises; when service ends, unused credits are flowed through the fuel-adjustment mechanism for other customers. NIPSCO's rider instead states unused remaining balance is forfeited and passed back through its FAC. |
| Annual true-up | Monthly billing is the crediting period; any excess credit is carried into future monthly bills rather than settled on a statewide annual true-up date. |
| Aggregate program cap | Net-metering availability was capped at 1.5% of each electricity supplier's most recent summer peak load; this is a supplier-specific statutory threshold, not a single statewide kW cap. |
| Program status | The statutory net-metering offering for new customers ended no later than July 1, 2022; new qualifying customers are served under utility EDG riders, while grandfathered participants continue under the statutory transition rules. |
| Grandfathering | Customers participating when the tariff terminates continue under net-metering terms until facility removal or replacement, or July 1, 2032, whichever is earlier; customers participating on December 31, 2017 are protected until facility removal or replacement, or July 1, 2047, whichever is earlier. |
| Regulator | Indiana Utility Regulatory Commission (IURC). |
| Governing rule | Indiana Code chapter 8-1-40, enacted through SEA 309, governs EDG and requires the rate formula of average marginal electricity price multiplied by 1.25; utility riders implement the approved tariffs. |
| Pending change | Utilities must update EDG rates annually: the statute and IURC orders require an updated rate by March 1, while utility billing effective dates vary. No unverified future statewide rate or decision number is asserted here. |
