Plug-In Solar in Indiana

No plug-in solar law exists in Indiana. Neither of the two 2026 bills, which covered kits up to 1,200 W, cleared committee before the session ended, so the usual utility interconnection rules still apply.

Indiana Plug-In Bills

SB 74 (2026): a Plug-in home solar units bill sponsored by Sen. Ford, with bipartisan co-authors: capped at 1,200 W, UL or NRTL certified, plus NEC compliant, with no utility approval, no fee, and no extra equipment; an outage disconnect is required, and the planned effective date is 1 Jul 2026. Referred on 8 Dec 2025 to the Senate Utilities Committee, it never had a hearing and died at the end of the 2026 session. Bill page
HB 1084 (2026): a Plug-in solar power systems bill sponsored by Rep. Hamilton: a system up to 1,200 W plugs into a standard outlet, is exempt from IURC interconnection rules, and needs no utility approval or fee. Referred on 5 Jan 2026, the bill went to the House Utilities, Energy and Telecommunications Committee, where no further action came before the session adjourned. Bill page

Indiana's Rule Today

Hooking up: A kit faces rooftop solar's IURC interconnection rules (170 IAC 4-4.3) because no plug-in law exists. Level 1 review applies to certified inverter systems up to 25 kW. Utilities may not charge an application fee for Level 1.

Net metering: Exported power earns credit through Excess Distributed Generation (EDG) riders, available at AES Indiana since 1 Jul 2022. The credit is 1.25 times the utility's average marginal energy price, and AES Indiana's own rate is 3.935 cents/kWh.

Indiana Kit Savings

PVWatts estimates that every 1 kW of panels in Indianapolis yields 1,355 kWh a year. Meanwhile, electricity costs Indiana homes 17.0 cents for each kWh they use in 2026 so far. Where you place an 800 W kit changes the numbers:

Where the panels go	kWh a year	Saved a year

Things Worth Knowing in Indiana

The money from exported power is small: AES Indiana's EDG credit paid 3.935 cents/kWh, and in 2024 homes paid 14.77 cents/kWh on average, so a plug-in kit earns its keep by covering your own use.
Indiana has no retail electric choice: EIA reports zero sales by energy-only suppliers, which means your local utility both supplies and delivers the power.
IURC rule makes Level 1 interconnection applications free, so the formal route costs you less.
