Grid & off-grid

Net metering calculator, Atlantic Canada

Model your solar bill for New Brunswick, PEI, or Newfoundland and Labrador, three provinces that each run their own net metering program under NB Power, Maritime Electric, or Newfoundland Power and NL Hydro.

Your numbers

1 Project details Optional
Shown on your exported report. Leave blank to skip.
2 Your usage and system
Find this on a recent utility bill, usually labeled kWh used.
Use your quoted or planned system size. Panel count times panel wattage divided by 1,000 gives a rough figure.
Solar production swings seasonally; pick a specific month type to see how your bill shifts.
Most utilities charge a flat customer or connection fee regardless of usage.
3 Your location and rate
Defaulted to Atlantic Canada's average peak sun hours. Adjust if you know your local figure.
Defaulted to Atlantic Canada's current average residential rate. Your utility's actual rate may differ.
Atlantic Canada typically credits exports around 100% of retail. New Brunswick and PEI net metering programs both credit exports 1:1, grouped here given closely matching policy.
Some utilities charge progressively higher per-kWh rates as monthly usage climbs into higher tiers.
Accounts for inverter loss, wiring loss, dust, and temperature derate combined.
Informational only. A monthly cycle means unused export credit does not carry to the next bill; annual and rolling cycles do.

How it works

Three steps to your Atlantic Canada solar bill estimate

Step 1

Enter your usage, system size, and season

Pull your monthly kWh from a recent bill and enter your planned or quoted system size in kW. New Brunswick homeowners weighing NB Power's pending rate change should try the export credit level both at full retail and at the proposed 6.77 cents/kWh to see the range. Select a season to model a specific month rather than only an annual average.

Step 2

Confirm your rate, tier, and export credit

A typical NB Power residential rate and full retail export credit are filled in by default, since all three provinces currently credit at 1:1. Swap in your own utility's tariff numbers, tier bracket, and fixed monthly fee if you have a recent bill or interconnection agreement showing them.

Step 3

Compare the result to a full retail scenario

New Brunswick homeowners can run the net billing vs net metering comparison tool to see what NB Power's proposed avoided-cost rate would cost compared to the current full 1:1 retail crediting.

How net metering works in Atlantic Canada

New Brunswick, PEI, and Newfoundland each run their own program

New Brunswick (NB Power), Prince Edward Island (Maritime Electric), and Newfoundland and Labrador (Newfoundland Power and NL Hydro) each operate net metering independently, all currently crediting exports at the full retail rate for systems up to 100 kW, with annual reconciliation dates that differ slightly by province. NB Power resets on March 31 each year; PEI resets December 31. See the glossary entry for demand charge if that term is new to you. The credit rate only matters once it becomes a payback period. The levelized cost of energy calculator in our Savings & Payback section can help you work out how long the system takes to pay for itself.

New Brunswick has a significant proposed change pending as of mid-2026

NB Power filed a proposal with the New Brunswick Energy and Utilities Board on April 30, 2026, as part of its broader rate design modernization, that would replace 1:1 retail-rate net metering with a lower avoided-cost export credit around 6.77 cents/kWh, add a new demand charge, and raise the non-residential system cap to 500 kW, with exceptions up to 1 MW under consideration. As of now, nothing has been approved. NB Power's own summary of the filing states that existing participants, and anyone approved before the changes take effect, would keep the current rules for up to 10 years.

PEI and Newfoundland aren't affected by New Brunswick's filing

The NB Power proceeding is specific to New Brunswick and has no bearing on Prince Edward Island's or Newfoundland and Labrador's net metering terms, which remain governed by their own separate provincial frameworks. Saint John Energy and Edmundston Energy, two New Brunswick municipal utilities, also aren't directly touched by NB Power's filing since they set their own independent rules. Run the tax credit and rebate estimator for Atlantic Canada with your own numbers before you decide.

Provincial rebates stack on top of net metering in each province

New Brunswick's Total Home Energy Savings Program pays roughly $200/kW up to $3,000 for eligible residential systems, with rebate registration closing May 27, 2026. PEI offers a Solar Electric Rebate Program at $1,000/kW up to $10,000. These upfront incentives are separate from and in addition to whatever net metering credit applies, and the tax credit and rebate estimator for Atlantic Canada can total up both provincial programs with any other incentives you qualify for.

Interconnection and the off-grid comparison

Whether you're with NB Power, Maritime Electric, or Newfoundland Power and NL Hydro, connecting a system requires a standard interconnection application, and the grid interconnection cost estimator covers what to budget for. With full retail crediting still the norm across all three provinces, staying grid-tied remains far cheaper than going fully off-grid, and the grid tie vs off grid comparison tool shows how much cheaper.

Questions Net metering is only part of what you can claim. The tax credit and rebate estimator in our Rebates & Incentives section estimates the tax credit and rebates available for your state.

Frequently asked

New Brunswick, PEI, and Newfoundland and Labrador each run independent net metering programs, all currently crediting exports at the full retail rate for systems up to 100 kW.
