Net Metering Program

Receive energy credits on your bill for the amount of power you generate

This program is designed to allow you to generate your own electricity from renewable energy to offset your individual usage each month. We install one meter capable of measuring energy you are consuming as well as measuring the amount you are generating. If you generate more than what you need, you’ll receive energy credits that can be applied to future usage. Please note, availability is limited.

Here are a few additional program details:
  • Must be an existing NIPSCO electric customer
  • Must be wind, solar or hydroelectric projects
  • Credit is applied to your bill, offsets individual usage
  • Supports generation projects up to 1 megawatt (MW)
  • Interconnection and Net Metering agreement are required
  • Customer is responsible for infrastructure upgrades and installation costs
  • Customer is responsible for maintenance of the generating device and interconnection wiring 

Process To Install/Connect Your Equipment

The following information will assist you with the interconnection process. The level and type of interconnection will vary with the type of customer and the size of the generator.


STEP 1: Research

We encourage you to research the interconnection process to understand all requirements (including potential municipal restrictions, building and zoning requirements, insurance requirements, safety regulations, application fees, installation, electrical requirements, etc.). Below are some resources to assist you.

  • DSIRE - Database of state incentives for renewable and energy efficiency projects.
  • PV Watts Calculator – Estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems.
  • Net Metering Engineering Standard - Requirements and guidelines for interconnection of customer owned, (DR) Distributed Resource (DR) generation source, to NIPSCO’s electric system
  • Riders – Approved rates & charges and rules & regulations

STEP 2: Submit Application (Note the Deadlines)


Interconnection Deadlines
All interconnections are subject to completion of program and interconnection process requirements, resource availability, holiday schedules, inclement weather, and other unforeseen system emergencies. If your goal is to complete a new net metering project by December 31, 2017, you must submit a complete interconnection application no later than the dates listed below, depending on the size of the system.

Submission of an Interconnection Request by these dates does not guarantee that the interconnection process will be complete by the end of the year. Alternately, an Interconnection Request received after the recommended deadline may be interconnected by the end of the year depending on resource availability; however, prioritization will be given to requests received by these dates.

The following dates are for distribution interconnected generation systems intended to be operational by December 31 of any year.

10kW and below:
NIPSCO must receive a complete Interconnection Request by October 19, 2017. Generation systems must receive electrical inspection approval (necessary to commission the system and set a meter) by December 12, 2017.

Greater than 10kW:
NIPSCO must receive a complete Interconnection Request by October 19, 2017. Generation systems must receive electrical inspection approval (necessary to commission the system and set a meter) by December 12, 2017 .

Greater than 500kW:
Evaluation is on a case-by-case basis. NIPSCO recommends allowing a minimum of six months to interconnect large generation projects.

Customer submits interconnection application:

STEP 3: Technical Review

NIPSCO reviews application and provides next steps. A technical review is conducted to determine if the project can move forward, or if an additional study is needed to determine the impact to the broader electric distribution system. This additional study may be required before moving to the next step.

STEP 4: Approvals & Construction

Once all approvals are complete, construction begins.

STEP 5: Agreements

Customer signs applicable agreements. When agreements are complete, a new meter is installed.
