Homes in Hammond and across Northwest Indiana are served by NIPSCO. Indiana closed traditional net metering under its 2017 solar law, so new solar customers now get Excess Distributed Generation (EDG) credits worth 125% of NIPSCO’s market energy price, recently about 5 cents per kWh, far below the roughly 18.15 cents you pay to buy power. So Hammond solar pays best on the power you use yourself, and batteries help.
- Indiana residential power runs about 18.15 cents per kWh (EIA, May 2026), so a Hammond bill is offset at full value only for the power you use on-site.
- Your utility is NIPSCO (Northern Indiana Public Service Company), which serves Lake, Porter, and LaPorte counties, including Hammond, Gary, Merrillville, and Portage. Confirm it on your electric bill before you compare quotes.
- New net metering ended. NIPSCO and Indiana’s other big utilities stopped enrolling new net-metering customers on July 1, 2022 under Senate Enrolled Act 309; new systems go on the EDG tariff (Rider 689) instead (NIPSCO EDG).
- EDG credits exports at 125% of market price, recently around 5 cents per kWh. That rate floats with the market, so verify NIPSCO’s current EDG credit before you sign.
- The 30% federal homeowner credit (Section 25D) ended for expenditures made after December 31, 2025 (IRS), so a 2026 cash or loan buyer in Hammond cannot claim it.
If you own a home in Hammond or anywhere in Northwest Indiana, this is how rooftop solar actually pays you back in 2026, told straight. Hammond sits on the Chicago-metro Indiana side, and two things drive the math here: NIPSCO is your utility, and Indiana has replaced full net metering with lower export credits. NIPSCO now credits the power you send to the grid at a fraction of the retail rate, so the value of Hammond solar comes mostly from the power you use in your own home. This page covers your exact utility, the local permit, what a NW Indiana roof produces, and how to tell if solar is a good fit.
Using NREL PVWatts and the current EIA rate, MySolarFY estimates a typical 7 kW rooftop system in Hammond (ZIP 46320) produces about 9,250 kWh a year (NREL PVWatts v8), on a solid Midwest sun resource of about 4.6 kWh per square meter per day. That output is worth roughly $1,680 a year at Indiana’s 18.15 cents per kWh residential rate (EIA, May 2026), but you capture the full value only on the power you use on-site, since NIPSCO credits exports near 5 cents under EDG.

Who is your electric utility in Hammond and NW Indiana?
For homes in Hammond and across Northwest Indiana, the utility is NIPSCO, the Northern Indiana Public Service Company. NIPSCO serves Lake, Porter, and LaPorte counties and the wider northern region, so Hammond, Gary, Merrillville, Portage, Michigan City, and Valparaiso are all NIPSCO electric territory. This matters because your utility sets your rate plan and how it credits the solar power you export. The fastest way to confirm is to look at your own electric bill; it names your utility. Once you know you are on NIPSCO, you can read Indiana’s statewide picture on our Indiana solar guide and check typical pricing on our Indiana solar cost guide.
The big change: EDG replaced net metering
Indiana no longer offers full retail net metering to new solar customers. This is the most important shift to understand about Hammond solar in 2026. Under Senate Enrolled Act 309, the 2017 state solar law, NIPSCO and Indiana’s other investor-owned utilities stopped enrolling new net-metering customers on July 1, 2022. New rooftop systems now go on the Excess Distributed Generation (EDG) tariff, Rider 689, which credits the power you export at 125% of NIPSCO’s market energy price rather than the full retail rate (NIPSCO Excess Distributed Generation). That EDG credit has recently worked out to roughly 5 cents per kWh, but it floats with the market, so verify NIPSCO’s current EDG rate before you sign. Homeowners who were already on net metering were grandfathered for a set period under SEA 309; if that is you, confirm your remaining term with NIPSCO. For the mechanics of how export credits work, see how net metering credits your solar exports.
What this means in plain terms: compared with the roughly 18.15 cents you pay to buy power, an exported kWh is worth only about a quarter as much in Hammond under EDG. So the value of your system comes mostly from the power you consume on-site. Sizing to your own usage and shifting big loads, like laundry, EV charging, and running the air conditioning or heat pump during daylight, into sunny hours protects far more of your savings than oversizing for export ever could. To see how offsetting your own usage lowers the bill, read how solar lowers your electricity bill.
Why batteries matter more in NW Indiana now
A home battery lets you keep the power you would otherwise sell cheap. Because an exported kWh earns roughly 5 cents under NIPSCO’s EDG tariff while a kWh you use is worth about 18.15 cents, storing your midday surplus and using it in the evening captures around three to four times the value of exporting it. In a NW Indiana home, storage also carries your evening load, when the panels are winding down but the house is still busy, and it adds backup during the storms and grid outages that hit the Chicago-metro area. A battery adds up-front cost and is not right for every home, so treat it as a payback question, not a default. For a framework on running those numbers, see our guide on whether solar panels are worth it.
Hammond permits and interconnection
For a home inside Hammond city limits, the City of Hammond issues the permit. Rooftop solar is handled by the City of Hammond Inspections Department through its Building Division at Hammond City Hall, and Indiana requires a separate electrical permit for the wiring, so most solar jobs pull both a building and an electrical permit. A licensed installer normally pulls these permits and prepares the plan set for you. Separately, NIPSCO runs the interconnection application and approves your system to connect and export under the EDG tariff, which is a different step from the city permit. A good local installer manages both the Hammond permit and the NIPSCO interconnection so you are not chasing paperwork.
Hammond and federal tax credits: what is gone in 2026
The 30% federal homeowner credit has ended, so do not count on it. The federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025 under the One Big Beautiful Bill Act, so a Hammond homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS). Indiana does not offer a state solar income-tax credit, but it does exempt the added home value from solar from your property tax assessment and exempts qualifying solar equipment from state sales tax; confirm current terms with the Indiana Department of Local Government Finance and Department of Revenue, and see the details on DSIRE. One federal credit still exists but is not yours to claim: Section 48E is a commercial credit that the business owning a leased or PPA system claims, not the homeowner. For the full timeline, see what the federal solar tax credit change means in 2026.
How you pay changes what you get
How you finance solar decides who owns the system and who claims any remaining benefit. This is the part of a quote worth reading closely.
| How you pay | Up-front cost | Who owns it | Export credits |
|---|---|---|---|
| Cash | Full system price | You | Credited to you |
| Solar loan | Little or none, financed over time | You | Credited to you |
| Lease or PPA | $0-up-front where you qualify | A third-party company | You still see bill credits; the company keeps ownership and any commercial credit |
If you own the system (cash or loan), you keep the EDG export credits and any bill savings. If you lease or sign a PPA, a third party owns the panels, you get a lower or fixed power price with no up-front cost, and that company claims any commercial tax credit, not you. Neither path gives a 2026 Hammond homeowner the federal residential credit, since it ended after December 31, 2025. Solar panels are not free, and a lease or PPA is a long-term contract, so compare the total cost of each path before you decide.
How to choose a solar installer in Hammond

Frequently asked questions
Who is my electric utility in Hammond, Indiana? It is NIPSCO, the Northern Indiana Public Service Company, which serves Hammond and the wider NW Indiana region including Gary, Merrillville, and Portage. Your electric bill names your utility. It matters because NIPSCO sets your rate plan and credits your exported solar power under Indiana’s EDG rules, which shape your solar payback.
Does Hammond still have net metering in 2026? No, not for new customers. NIPSCO and Indiana’s other big utilities stopped enrolling new net-metering customers on July 1, 2022 under Senate Enrolled Act 309. New solar systems go on the Excess Distributed Generation (EDG) tariff, which credits exports at 125% of NIPSCO’s market energy price, recently about 5 cents per kWh, well below the roughly 18.15 cents you pay to buy power.
What does a Hammond solar system produce? A typical 7 kW rooftop system in Hammond (ZIP 46320) produces about 9,250 kWh a year in our NREL PVWatts estimate, on a solid Midwest sun resource of about 4.6 kWh per square meter per day. Your real output depends on roof pitch, direction, and shade, so get a written production estimate for your specific roof.
Who issues the solar permit in Hammond? For homes inside Hammond city limits, the City of Hammond Inspections Department issues the building permit through its Building Division, and Indiana requires a separate electrical permit. NIPSCO separately runs the interconnection approval. A licensed installer normally handles all of it.
Is there still a solar tax credit in Indiana in 2026? The 30% federal homeowner credit (Section 25D) ended for expenditures made after December 31, 2025, so a 2026 cash or loan buyer cannot claim it. Indiana has no state solar income-tax credit, but it exempts the added home value from solar from your property tax assessment and exempts qualifying solar equipment from sales tax; confirm current terms with the Indiana Department of Local Government Finance and Department of Revenue before you decide.
Is solar worth it in Hammond now that exports pay less? It can be. Indiana’s 18.15 cents per kWh retail rate means every kWh you use yourself offsets real money, and a NW Indiana roof makes a solid amount of power. The weak spot is exported power, credited near 5 cents under EDG, so payback depends on sizing to your own usage and, for many homes, adding a battery. Run your own numbers with a written production estimate before you commit.
