FortisBC Solar Net Metering Guide: Service Area, 50 kW Limit, kWh Bank Credits & Approval Steps (BC)

If you're in British Columbia's Southern Interior and searching "FortisBC solar" or "FortisBC net metering", the big question is: How do I connect solar to FortisBC and how do credits work?

FortisBC runs a Net Metering Program that lets eligible customers generate renewable electricity (commonly solar), reduce their electricity bill, and bank excess generation for future bills using a Kilowatt Hour (kWh) Bank.

This guide covers:

• Where FortisBC provides electricity service (and who it's for)
• Eligibility rules (including the 50 kW cap)
• How FortisBC's kWh Bank works
• Application + approval steps for connecting solar
• Rate context that affects savings
• How SolarCalculatorCanada helps estimate savings for FortisBC customers

⚡ Quick Fact: FortisBC serves almost 1.3 million customers across 135 communities in British Columbia, making it the second-largest electricity utility in the province.

FortisBC is a major energy provider across BC and states it serves almost 1.3 million customers across 135 communities (plus 58 First Nations communities), operating both electricity and natural gas infrastructure.

For electricity specifically, FortisBC states it provides electricity service for the Southern Interior region of BC.

A FortisBC media release also describes FortisBC Inc. as serving about 195,300 direct and indirect electricity customers in BC's Southern Interior.

Common Southern Interior Communities (FortisBC Electricity)

Depending on your address, FortisBC electricity service is commonly associated with communities such as:

• Kelowna
• Penticton
• Trail
• Castlegar
• Creston
• Grand Forks
• Rossland
• Nelson
• Osoyoos
• Vernon

Important: Always confirm by checking your electricity bill—BC has multiple utilities (including BC Hydro) and some municipal providers.

Yes. FortisBC's Net Metering Program is for customers who want to generate renewable energy to reduce their FortisBC electricity bill. It supports residential, commercial, and irrigation customers.

✅ Bottom Line: FortisBC actively supports solar installations through their net metering program for eligible customers in the Southern Interior.

FortisBC lists several eligibility requirements, including:

• Your generator must use a renewable source (solar qualifies)
• The generation equipment must be on your property
• The power produced serves your property
• Your system must be designed to offset some/all of your consumption
• Maximum allowable generating capacity is 50 kW
• Production is limited to offset your expected annual consumption

These limits are important for searches like:

• "FortisBC net metering limit"
• "FortisBC solar size limit"
• "FortisBC 50 kW net metering"

System Size Recommendations

• Residential systems: Typically 3-8 kW
• Small commercial: 8-25 kW
• Larger systems: 25-50 kW (FortisBC maximum)
• Maximum: 50 kW aggregate capacity

Most residential solar systems fall well within these limits.

FortisBC explains that net metering uses a meter that tracks:

• kWh delivered to you (what you use from the grid)
• kWh received from you (what you export)

If you generate more than you use in a billing period, the extra energy is banked and can be used in a future billing period.

Understanding Your kWh Bank

FortisBC notes:

• Most customers use more electricity than they generate, but the kWh bank can lower annual bills
• Excess electricity is settled annually (rather than each billing period at the same rate paid to other producers)
• Credits carry forward within the annual cycle
• Annual settlement: Remaining credits are addressed at year-end

This banking system is particularly valuable for seasonal variation, helping homeowners offset winter consumption with summer production.

FortisBC outlines a straightforward process:

1. Submit the Net Metering Application

• Complete FortisBC's official net metering application form
• Include system specifications and site details

2. FortisBC Reviews and Approves for Construction

• FortisBC assesses technical feasibility
• Confirms eligibility and system design
• Usually takes 2-4 weeks

3. Build Your Generation Facility After Approval

• Hire a certified solar installer
• System must meet BC electrical codes
• Requires BC Safety Authority (Technical Safety BC) inspection

4. After Construction, Submit the Interconnection Agreement

• Your contractor provides inspection documentation
• FortisBC completes final verification
• Grid connection is activated

Total Timeline

Most FortisBC solar projects take 4-8 weeks from application to grid connection.

FortisBC doesn't present a single "flat fee" on the net metering overview page, but in practice most grid-tied solar projects can involve:

• Application/engineering review (utility-side)
• Bi-directional metering setup
• Inspection/commissioning requirements
• Possible upgrades if local equipment needs it

Best practice: Fees and requirements are confirmed during the review/approval stage once FortisBC evaluates the specific connection point and system design.

Your solar savings depend heavily on your rate structure (fixed + variable charges) and annual rate changes.

FortisBC notes:

• Rates are reviewed annually by the British Columbia Utilities Commission
• As of January 1, 2026, FortisBC electricity rates increased by 3.63%

This is useful context for "is solar worth it" searches because rate increases increase the value of offsetting grid electricity over time.

Why This Matters

• Higher electricity rates = greater annual savings from solar
• Rate increases protect your solar investment (locked-in value)
• kWh credits offset rising grid rates

Often yes, especially in the Southern Interior where:

• Electricity rates are rising annually
• Excellent solar potential in Kelowna, Penticton, and surrounding areas
• kWh banking system maximizes value of excess generation
• Federal and provincial incentives available

Typical FortisBC Solar Savings

• Annual savings: $600-$1,300/year for average homes
• Payback period: 10-14 years
• 25-year savings: $15,000-$35,000+
