Alberta Net Billing (aka Net Metering)

Net billing is Alberta’s billing arrangement that allows homeowners and businesses with solar energy systems to earn credits for the excess electricity they generate and send back to the grid. Unlike traditional net metering used in other provinces, Alberta’s net billing system operates under the provincial Micro-Generation Regulation and offers unique advantages for solar owners.

The #1 Solar ROI Accelerator

In Alberta, small-scale micro-generators (systems under 150 kW) are currently compensated at the retail rate for the electricity they export to the grid. This means you earn the same rate for excess solar energy that you pay when buying electricity from the grid—a significant financial benefit compared to most net billing schemes that only pay wholesale prices.

When your solar panels produce more electricity than your home or business needs, the surplus flows back into Alberta’s electrical grid through a bidirectional meter. Your electricity retailer then credits your account for this exported energy, which directly offsets your future electricity consumption charges.

How Net Billing Works

Step 1: Solar Generation

Your solar panels convert sunlight into DC electricity, which an inverter converts to usable AC power for your home or business.

Step 2: Self-Consumption First

Your property uses the solar power first, automatically reducing the amount of electricity you need to purchase from the grid. This happens in real-time throughout the day.

Step 3: Export Excess Energy

When you generate more electricity than you’re currently using, the excess energy flows back to the grid automatically through your bidirectional meter.

Step 4: Earn Bill Credits

Your electricity retailer credits your account at the retail electricity rate for all exported energy. These credits appear on your monthly bill as “Micro-Generation Credits.”

Step 5: Credits Offset Future Consumption

When you consume electricity from the grid (at night or during periods of low solar production), your accumulated credits offset these charges, dramatically reducing your bill.

Understanding Your Solar Bill Components

An Alberta electricity bill with solar includes several key components:

Energy Charge: Cost for electricity consumed from grid (variable per kWh)

Solar Impact: ✓ Significantly reduced by solar generation

Micro-Generation Credit: Credits earned for excess solar exported to grid

Solar Impact: ✓ Directly offsets energy charges

Distribution Charges: Fixed fees for maintaining local power lines

Solar Impact: ✗ Not reduced by solar

Transmission Charges: Fees for province-wide grid infrastructure

Solar Impact: ✗ Not reduced by solar

Admin/Service Fees: Monthly service and billing charges

Solar Impact: ✗ Not reduced by solar

Important: While you earn credits for exported energy at the retail rate, you still pay fixed delivery charges (distribution, transmission, and admin fees) as long as you remain connected to the grid. However, this is beneficial—these fees are a small price for using the grid as your backup energy source and participating in net billing!

Key Benefits of Alberta’s Net Billing System

1. Retail Rate Credits

Earn the same rate for exported energy as you pay for grid electricity—unlike most jurisdictions that only pay wholesale rates. This is the single most important factor that makes solar economically attractive in Alberta.

2. Monthly Bill Offsets

Credits automatically reduce your next month’s electricity charges, providing immediate cash flow benefits. You see the financial return every single month from day one.

3. 12-Month Credit Banking

Unused credits roll over month-to-month for up to 12 months, allowing summer surplus to offset winter consumption. This is crucial in Alberta’s seasonal climate where you’ll generate 3-4x more power in July than January.

4. Annual Cash Compensation

If you have leftover credits at the end of your 12-month cycle, your retailer pays you in cash for the unused balance. While systems are typically sized to avoid this, it’s an important safety net.

5. Alberta’s Sunshine Advantage

With 312 sunny days per year—the most in Canada—Alberta solar systems generate consistently strong production and credits. Calgary averages 2,396 hours of sunshine annually, while Edmonton sees 2,345 hours.

6. Grid Connection Benefits

Remain connected to the grid for backup power at night without expensive battery systems, while still earning credits when producing. The grid becomes your “virtual battery” at no additional cost.

7. No Interconnection Fees

Unlike other provinces where connection studies and meter installation can cost $1,000-$3,000, Alberta’s Micro-Generation Regulation prohibits utilities from charging homeowners for interconnection or bidirectional meters.

8. Protection from Rate Volatility

Lock in your energy costs while grid rates historically increase 2-4% annually. Your savings grow larger every year as grid electricity becomes more expensive.

Maximizing Your Net Billing Benefits

1. Right-Size Your System

Alberta’s Micro-Generation Regulation limits system size to match your annual energy consumption. Working with experienced solar advisors ensures your system is sized to:

Generate enough to cover 85-100% of your annual needs
Avoid oversizing which provides diminishing returns due to the 12-month credit expiry
Maximize summer overproduction to bank credits for winter
Account for future consumption increases (EV charging, heat pumps, etc.)

Sizing Example: If your home uses 9,000 kWh annually, a 7.5 kW solar system producing approximately 9,500 kWh per year provides optimal coverage. The 500 kWh buffer (5%) accounts for system degradation over time and ensures you maximize credit accumulation without significant waste.

2. Understand Seasonal Variations

Alberta’s solar production varies dramatically by season. A properly sized system will:

Generate 70-80% of annual production during April-September
Build substantial bill credits during sunny summer months (May-August)
Use banked credits to offset higher winter consumption
Achieve net-zero or near net-zero annual electricity costs

Monthly Production Pattern (7.5 kW system in Calgary):

January: 280 kWh
April: 950 kWh
July: 1,200 kWh
October: 700 kWh
December: 220 kWh

Understanding this pattern helps you anticipate cash flow and credit accumulation throughout the year.

Choose the Right Electricity Retailer

Some Alberta retailers offer enhanced programs for micro-generators:

Seasonal Solar Rates: Some retailers offer higher export rates (up to 30¢/kWh) during summer months when you’re generating surplus, and lower import rates in winter when you’re consuming. This strategy can increase annual savings by 15-25%.

Solar Clubs: Special programs like the Solar Club that maximize credit accumulation and may offer bonus credits during peak production months.

Flexible Rate Switching: Ability to change between fixed and variable rates, or between import and export-optimized plans seasonally to capture maximum value.

Time-of-Use Optimization: While less common, some retailers offer time-of-use rates that allow you to export during peak rate hours and import during off-peak hours for additional savings.

Pro Tip: Review your retailer options annually. The Alberta electricity market is competitive, and retailers frequently update their micro-generation programs. Switching retailers every 1-2 years to capture the best rates can add $200-$400 to your annual savings.

Net Billing vs. Battery Storage

Many homeowners ask whether they need batteries with solar. In Alberta’s net billing system, the grid essentially acts as your battery:

Net Billing (Grid as Battery):

Upfront Cost: $0 additional
Maintenance: None required
Capacity: Unlimited storage via credits
Reliability: Alberta’s stable grid infrastructure
ROI Impact: Maximizes returns—typically 10-12 year payback

Battery Storage System:

Upfront Cost: $10,000-$15,000+ additional
Maintenance: Battery replacement every 10-15 years ($8,000+)
Capacity: Limited to battery size (10-15 kWh typical)
Reliability: Works during grid outages
ROI Impact: Extends payback period to 18-25+ years

Our Recommendation:

For most Alberta homeowners, net billing provides the optimal financial return without batteries. You get the benefits of energy storage through bill credits while avoiding the high costs and maintenance of physical batteries. This keeps your system affordable and your ROI strong.
