NIPSCO commercial incentives help eligible businesses in northern Indiana reduce the cost of energy-efficient equipment, system improvements, and construction projects. Four pathways serve different needs: Prescriptive incentives for listed equipment replacements, Custom incentives for projects requiring individual savings calculations, Retro-Commissioning incentives for optimizing existing systems, and New Construction incentives for exceeding applicable efficiency baselines.

Choosing the right pathway before purchasing equipment helps protect eligibility and establish a realistic project budget.

Key Takeaways

• Prescriptive incentives cover qualifying equipment replacements, with pre-approval required when estimated incentives exceed $10,000.
• Custom and New Construction projects require pre-approval before equipment purchases or installation.
• Qualifying electric Retro-Commissioning projects offer separate study support paid to approved providers after eligible measures are installed.
• Eligible natural gas projects submitted and installed July 1 through December 31, 2026, may receive a 10% bonus while funding remains available.
• NIPSCO lists November 16, 2026, as the completion deadline for current 2026 incentives. Confirm how this deadline affects projects pursuing the December bonus window.

Which NIPSCO Incentive Program Fits Your Project?

The best program depends on whether you are replacing equipment, improving system operation, or constructing a new space.

Retro-Commissioning falls under NIPSCO’s Custom Incentive Program, though it addresses a distinct project need.

What Projects Qualify for NIPSCO Prescriptive Incentives?

The NIPSCO Prescriptive Incentive Program supports qualifying replacements of less-efficient equipment with equipment meeting published requirements. Incentive amounts depend on the measure, equipment size, efficiency, and replacement conditions.

Common opportunities include:

• Lighting: qualifying LED fixtures, retrofit products, occupancy sensors, and luminaire-level lighting controls.
• HVAC: qualifying cooling equipment, variable-speed drives, smart thermostats, and specified tune-ups.
• Natural gas: qualifying furnaces, boilers, steam traps, pipe insulation, and water-heating equipment.
• Other systems: qualifying refrigeration controls, food-service equipment, agricultural equipment, and compressed-air improvements.

NIPSCO lighting rebates and HVAC rebates depend on verified performance specifications. Qualifying fixtures with occupancy sensors or luminaire-level lighting controls (LLLC) may receive higher incentive tiers than comparable fixtures without controls. HVAC equipment must meet the applicable capacity thresholds and efficiency requirements for its measure category. Confirm the exact model, configuration, and replacement conditions before calculating an expected rebate.

Prescriptive projects with estimated incentives exceeding $10,000 require pre-approval before purchase or installation. Applications must be submitted within 90 days of installation, subject to program-year deadlines.

When Should Businesses Use the NIPSCO Custom Incentive Program?

The NIPSCO Custom Incentive Program serves existing-facility projects that do not fit Prescriptive measures. It can accommodate improvements involving lighting, HVAC, compressed air, refrigeration, motors, food service, agriculture, and data-center systems.

Custom review evaluates the proposed improvement against an accepted baseline. Equipment specifications, operating hours, existing conditions, and savings calculations help establish the incentive.

These rates calculate project incentives from approved energy savings; they are not ongoing utility-bill credits. Final awards remain subject to program review and applicable limits.

All Custom projects require pre-approval before equipment is purchased or installed.

Does NIPSCO Pay for Retro-Commissioning?

NIPSCO retro-commissioning incentives reward approved improvements that optimize existing building or industrial systems. Retro-Commissioning, or RCx, examines how equipment operates and identifies changes that reduce energy waste while meeting facility needs.

Potential opportunities include correcting operating schedules, adjusting controls, and improving the performance of compressed-air or refrigeration systems. Each proposed measure must satisfy program requirements.

Qualifying electric RCx projects can also receive a separate study incentive of $0.01 per kWh saved. This payment goes to the TRC-approved RCx provider and is capped at the study cost.

Study incentives apply exclusively to approved electric RCx measures and are paid after those measures are installed. They do not cover standalone audits or natural gas assessments.

What Qualifies for NIPSCO New Construction Incentives?

NIPSCO new construction incentives support projects that exceed current statewide building-code requirements or accepted industry baselines.

Eligible project types include new buildings on previously undeveloped footprints, additions or expansions, and gut rehabilitations involving a change of purpose that requires replacement of electrical systems or equipment.

Potential improvements include efficient lighting, HVAC, and natural gas systems. Savings are evaluated against the applicable baseline, not the energy use of an older building.

Coordinate owners, architects, engineers, and contractors during schematic design to establish the efficiency baseline, identify qualifying measures, and prepare the application. Before placing orders or making purchases, secure formal pre-approval and sign and return the incentive offer. Purchasing before completing this process makes those items ineligible for incentives; discuss any proposed early ordering arrangements with TRC.

What Is the NIPSCO 10% Natural Gas Bonus?

NIPSCO offers a 10% bonus on approved incentives for eligible natural gas projects submitted and installed between July 1 and December 31, 2026. Participating pathways include Prescriptive, Custom, Retro-Commissioning, New Construction, and Small Business Direct Install.

For example, an approved $10,000 qualifying natural gas incentive could receive a $1,000 bonus, bringing the total to $11,000, subject to applicable limits and program approval.

The bonus increases the approved incentive, rather than reimbursing an additional 10% of total project cost. Funding is limited and awarded on a first-come, first-served basis.

How Does the Bonus Window Relate to the November Deadline?

NIPSCO’s published pages also state that projects must be completed by November 16, 2026, for current 2026 incentives, with projects submitted afterward subject to 2027 incentives and requirements.

The published language does not fully explain how that cutoff interacts with the December bonus window. Obtain written confirmation from TRC, NIPSCO’s program administrator, before relying on bonus eligibility for a project scheduled after November 16.

The 90-day application allowance should not be interpreted as an extension of either deadline.

Frequently Asked Questions

Can a business receive two NIPSCO incentives for the same equipment?

Equipment receiving a NIPSCO Midstream incentive through a participating dealer cannot also receive another NIPSCO program incentive for that same equipment.

Does every business in NIPSCO’s territory qualify?

No. Eligibility depends on the account’s electric or natural gas service rate code and participation in the applicable efficiency program. Large commercial and industrial accounts that have opted out of NIPSCO’s applicable energy-efficiency rider are ineligible for the associated incentives. Verify the project account before proceeding.

What should businesses document before removing existing equipment?

Record equipment quantities, model numbers, capacities, operating schedules, and existing conditions. Photographs and maintenance records can help support review, especially when savings depend on the original system.
