EPCOR Solar Guide (Alberta): Micro-Generation, Net Billing Credits, Approval Steps & How to Calculate Solar Power

If you're in an EPCOR service area in Edmonton or other Alberta regions served by EPCOR, going solar usually means registering as a micro-generator under Alberta rules. EPCOR explains that micro-generation includes small renewable systems (like solar panels) intended to meet part or all of your electricity needs, and it's supported through coordination with the Alberta Utilities Commission (AUC).

This guide covers:

• What EPCOR micro-generation is (Alberta)
• How net billing credits work (the "Alberta net metering" style)
• EPCOR application + approval steps (including ≥20 kW requirements)
• What to tell your electricity retailer so credits show up
• How SolarCalculatorCanada acts as your solar calculator + PV sizing tool

⚡ Quick Fact: EPCOR is one of Alberta's major electricity distributors serving Edmonton, Strathcona County, parts of southern Alberta, and other regions with micro-generation support through Alberta's regulatory framework.

EPCOR defines micro-generation as small-scale renewable generation (up to 5 MW) such as solar panels, wind, biomass, and more—built to offset your on-site electricity use.

EPCOR also notes that eligible micro-generation options must meet Alberta's greenhouse-gas intensity requirement (≤ 418 kg/MWh) to connect as micro-generation. Solar qualifies.

EPCOR states that when you export power, you receive bill credits based on your electricity retailer's energy rate (the credit appears on your monthly bill).

Micro-Generation vs. Other Options

• Micro-generation: Small renewable systems (typically residential 3-20 kW) registered with the AUC
• Solar Club: Larger systems with active management (Alberta-specific program)
• Standard net metering: Other provinces' approach

EPCOR customers typically use micro-generation for residential and small commercial solar.

Alberta's rules require net billing for micro-generators, and credits can be carried forward for up to 12 months to offset future electricity charges. The regulation also describes annual settlement of unused credits.

Alberta's official micro-generation guidance explains the roles clearly:

1. You apply to your distribution company (like EPCOR) and sign an interconnection agreement
2. Your retailer handles compensation and billing, crediting you for excess electricity you supply to the grid

Understanding Your Net Billing Credits

• Export tracking: Your meter tracks electricity exported to the grid
• Retailer credits: Your electricity retailer applies generation credits at their energy rate
• Monthly application: Credits typically appear on your monthly bill once registered
• 12-month carry-forward: Unused credits can offset future months
• Annual settlement: Excess credits are settled at least annually

This system is straightforward once your retailer is properly notified and your micro-generation registration is complete.

EPCOR's solar PV page explains the practical flow:

1. Your solar powers your home first
2. Excess goes through your power meter to the grid
3. The meter tracks exported energy, and EPCOR sends the measurement to your electricity retailer
4. If you've notified the retailer, they add a generation credit to your monthly bill for excess energy

Critical Step

Key takeaway: Even if your system is producing, credits may not appear until the retailer is properly notified and your micro-generation paperwork is complete.

Always ensure your electricity retailer (e.g., Enmax, Direct Energy, or other Alberta retailer) is aware of your micro-generation installation so they apply credits correctly.

EPCOR serves major Alberta communities including:

• Edmonton (primary service area)
• Strathcona County
• Southern Alberta (various municipalities)
• Other EPCOR-served regions (check your bill to confirm)

Always verify EPCOR is your distributor by checking your electricity bill, as Alberta has multiple distributors (Fortis, AltaLink, etc.).

Step 1: Design Your System (Size + Drawings)

EPCOR advises that for micro-generation projects 20 kW or larger, you should email them before starting design so they can identify special requirements.

EPCOR also lists detailed drawing elements they expect:

• Single line diagram
• Disconnects and grounding
• Equipment specifications
• Site-specific details

Step 2: Prepare the Documents EPCOR Requires

EPCOR's application page lists common required items:

• Site line diagram
• Site plan / real property report
• Manufacturer equipment specifications
• Permit information (e.g., City of Edmonton electrical permit number)
• Proof of ownership (if applicable)
• System design drawings

Step 3: Apply + Get Approvals + Sign Interconnection Agreement

Alberta's official guide confirms micro-generators must:

1. Apply to their distribution company (EPCOR)
2. Sign an interconnection agreement
3. Follow AUC guidelines (permits, site plan, contractor requirements)
4. Work with a licensed electrician (Technical Safety Alberta requirements)

Step 4: Grid Connection and Meter Upgrade

• EPCOR arranges bi-directional meter installation
• Your system is tested and commissioned
• Grid connection is activated
• Generation credits begin appearing on your bill (once retailer is notified)

Total Timeline

Most EPCOR micro-generation projects take 6-12 weeks from initial application to grid connection and credit activation, depending on complexity and ≥20 kW requirements.

Standard Residential Systems (Under 20 kW)

• Typically 3-10 kW for residential homes
• Standard application process
• No special engineering required

Larger Systems (20 kW or More)

EPCOR advises contacting them before starting design for ≥20 kW systems:

• Special requirements identification
• Network impact studies may be required
• Longer approval timeline
• More detailed drawings and specs

Maximum Micro-Generation Size

• EPCOR's upper limit: 5 MW (but residential is typically ≤20 kW)
• Designed for on-site consumption offset
• Export is secondary to self-consumption

Most EPCOR-area solar systems are designed to offset annual usage (so you don't overbuild and end up with excess credits you can't efficiently use before settlement).
