Net metering is the regulatory mechanism that turns Alberta solar from a science project into a financial decision. Without it, every kWh you produce at noon while you're at work would be wasted — the panels can't store electricity on their own, and the grid would just absorb it for free. Net metering forces the grid to remember every kWh you exported and bank it as credit you can spend later.
This is the definitive 2026 guide to how it actually works. Every claim is traced to the regulation, the Alberta Utilities Consumer Advocate, or the four distribution companies that operate the bi-directional meters. We’ll cover eligibility, credit rates, the four distribution-company processes (EPCOR, FortisAlberta, ATCO Electric, ENMAX), what happens at annual settlement, what changes when you sell your house, and how net metering combines with the Solar Club rate program for maximum 25-year value.
The 60-second answer
Your solar system produces electricity in real time, all day, on every roof in Alberta. Sometimes that’s more than your home is using; sometimes it’s less. Net metering is the regulated rule that says:
Every kWh you export to the grid earns you credit at the same rate your retailer charges you to import. 1:1, symmetrical, mandatory across every retailer in the province.
The credits roll forward month to month. At the end of your 12-month settlement cycle, any unused credits are paid out to you in cash by the retailer. The system is governed by Alberta’s Micro-Generation Regulation (Alta Reg 27/2008) under the Electric Utilities Act.
The regulation: Alta Reg 27/2008, last amended 2016
Alberta’s Micro-Generation Regulation came into force in 2008 and has been the foundation of residential solar in the province ever since. Two amendments matter to homeowners in 2026:
2016 size-cap increase. The maximum micro-generation system size was raised from 1 MW to 5 MW. This effectively brought farm-scale and small-commercial solar arrays under the same favourable regulatory framework. (Stellar Upgrades regularly installs farm-scale systems up to 200 kW capacity.)
Small vs large micro-generation distinction. The regulation now categorizes systems into two tiers:
| Category | Size range | Credit rate for exports | Typical use |
|---|---|---|---|
| Small micro-generation | Under 150 kW | Retailer's retail rate (or hourly wholesale at homeowner’s option) | Residential rooftops, small farm systems, small businesses |
| Large micro-generation | 150 kW to 5 MW | Hourly wholesale market price (set by AESO) | Commercial rooftops, large farm ground-mounts, multi-tenant buildings |
| Commercial generation (revenue-only) | Any size | Wholesale market only; not eligible for micro-generation | Power producers selling into the market without on-site consumption |
For a typical Alberta home, the relevant tier is small micro-generation. Residential systems range from 3 kW to 30 kW — well below the 150 kW cap — so the retail-rate credit applies in full.
Who is eligible (and who is not)
Three eligibility tests, all applied at install:
1. Grid-connected. Off-grid systems do not net meter (and Stellar does not install off-grid). The system must be electrically connected to the public distribution grid through a bi-directional meter.
2. Sized to offset on-site consumption, not to generate revenue. Per the regulation, micro-generation must be sized to your historical annual consumption. You cannot install a 30 kW system on a home that uses 6,000 kWh/year and call it micro-generation. Most residential systems are sized to roughly 100–110% of historical annual consumption (110% is the regulatory cap and the sweet spot we recommend).
3. Owner of the property or authorized by the owner. Renters cannot install micro-generation without the property owner’s written authorization and inclusion in the interconnection agreement.
What disqualifies you: trying to install in Medicine Hat (separate city utility, separate program), or in any of the six REA service areas excluded from the Solar Club program (though net metering itself can still apply — the REA exclusions affect Solar Club rate eligibility specifically). Generators sized purely to sell electricity for revenue with no on-site offset are classified as small-scale generation or distributed generation under different rules.
The four distribution companies and how each handles interconnection
Your retailer is who bills you. Your distribution company (also called the “wires company”) is who owns the actual poles, wires, and meter at your property. Net metering interconnection is handled by the distribution company, not the retailer. Alberta has four primary residential distribution companies plus a handful of city-owned and REA exceptions:
EPCOR Distribution & Transmission Inc. — Edmonton city. Per the EPCOR micro-generation page and EDTI Customer Connection Guide, the EPCOR interconnection process typically runs 4–6 weeks from physical installation completion to meter swap and Permission to Operate (PTO). EPCOR requires the City of Edmonton building permit, electrical permit, and the EDTI micro-generation application, all of which Stellar pulls and coordinates.
FortisAlberta — most surrounding communities and rural Alberta. FortisAlberta serves Sherwood Park, Leduc, Beaumont, Spruce Grove, St. Albert, Fort Saskatchewan, Stony Plain, Devon, Morinville, and most rural Alberta communities. Per FortisAlberta’s micro-generation page, applications are processed through PowerClerk (an online interconnection-management portal). Clean applications can move through faster than the EPCOR process; complex installs (long service runs, panel upgrades, neighbouring REA boundaries) take comparable time.
ATCO Electric — northern and southeastern Alberta. ATCO covers much of northern Alberta (north of Edmonton, including Athabasca, Slave Lake, Cold Lake, Lac La Biche), and a large portion of southeastern Alberta. ATCO follows the Alberta Utilities Commission’s Rules Respecting Micro-Generation closely, with the same 4–7 week typical interconnection timeline.
ENMAX — Calgary city. ENMAX is the city-owned distribution company for Calgary. ENMAX processes Calgary residential micro-generation applications under the same provincial regulation. Calgary is technically outside Stellar Upgrades’ standard service area (Edmonton + ~200 km radius); we discuss Calgary projects on a case-by-case basis at the free assessment.
Other: Cities of Lethbridge and Medicine Hat operate their own utilities. Lethbridge participates in standard Alberta net metering. Medicine Hat operates a separate municipal utility with its own micro-generation rules. Six Rural Electrification Associations (Peigan, Ermineskin, Wild Rose, Lakeland, North Parkland Power, Blue Mountain Power Co-op) operate as separate distributors with their own service-area rules.
The bi-directional meter
The mechanical heart of net metering. A standard residential meter measures only electricity flowing one direction (from the grid into the home). A bi-directional meter measures both directions independently — energy imported AND energy exported are tracked as separate cumulative totals. The two values are reported to your retailer at each billing cycle and the credit math runs against them.
Two technical points homeowners ask about:
Cumulative vs interval. Most Alberta residential bi-directional meters are cumulative — they total imports and exports over the billing period without recording the time-of-day pattern. Interval meters (less common in residential) record hour-by-hour data. The Solar Club program specifically requires the cumulative type, not the interval type. We coordinate with the distribution company to ensure the right meter type is installed for Solar Club enrollment.
Cost of the meter. Included in standard interconnection. Your distribution company supplies and installs the bi-directional meter as part of micro-generation activation. There is no additional fee to the homeowner.
Credit math: monthly rollover, annual settlement
How the credit account behaves over a year:
At the end of each billing cycle, your retailer calculates: kWh imported − kWh exported = net consumption. If exported is greater than imported, you have a credit balance that rolls forward to next month. If imported is greater than exported, the credit balance is drawn down before you pay for the remainder.
Worked example for a typical Edmonton home with an 8 kW system, sized to consume 7,800 kWh/year and produce ~9,600 kWh/year:
| Month | Imported (kWh) | Exported (kWh) | Net | Credit balance |
|---|---|---|---|---|
| April | 500 | 700 | +200 | 200 kWh |
| May | 400 | 1,100 | +700 | 900 kWh |
| June | 350 | 1,200 | +850 | 1,750 kWh |
| July | 400 | 1,150 | +750 | 2,500 kWh |
| August | 500 | 1,000 | +500 | 3,000 kWh |
| September | 650 | 800 | +150 | 3,150 kWh |
| October | 800 | 500 | −300 | 2,850 kWh |
| November | 900 | 300 | −600 | 2,250 kWh |
| December | 1,000 | 200 | −800 | 1,450 kWh |
| January | 950 | 250 | −700 | 750 kWh |
| February | 800 | 450 | −350 | 400 kWh |
| March | 650 | 650 | 0 | 400 kWh |
| Annual settlement | — | — | — | +400 kWh paid out in cash |
This homeowner ends the year with 400 kWh of unused credits, which the retailer is legally required to compensate in cash at annual settlement. At a 23¢/kWh blended retail rate, that’s roughly $92. On Solar Club’s LO rate (8.40¢/kWh, the most common settlement reference for Solar Club retailers), it would be roughly $34. The exact settlement-rate detail depends on your specific retailer’s contract; read it before signing if cash payout matters to you.
What stays on your bill after going solar
Net metering eliminates the energy line of your bill for a properly-sized system. It does not eliminate every charge on your bill. Three things remain:
1. Distribution charges. The fee for using your distribution company’s wires and infrastructure. Partially proportional to consumption (so net metering reduces it) and partially a fixed daily charge that applies regardless. Typical: $20–$50/month before solar, $5–$20/month after.
2. Transmission charges. The fee for the high-voltage transmission grid operated by the Alberta Electric System Operator (AESO) and the transmission utilities. Similar structure to distribution — partly variable, partly fixed.
3. Rate riders, admin fees, and fixed charges. Small monthly fixed charges that apply regardless of consumption. Typical $5–$15/month aggregate. Most retailers charge a $7–$10 admin fee.
For an Edmonton home with a 110%-of-consumption system on a Solar Club retailer, post-solar bills typically look like $0–$15/month most months — meaningful when compared to the $200–$400/month the household paid for grid electricity before solar. With Solar Club’s summer surplus credits (35¢/kWh) banked against winter imports (8.40¢/kWh) plus the Pre-Solar Rate during install wait, fixed grid charges can be effectively zeroed for many months. See the Solar Club Alberta guide for the rate-switching mechanics.
How net metering combines with the Solar Club rate program
This is where Alberta’s residential solar economics genuinely beat the rest of the country. The Solar Club layers a retailer-side rate plan on top of net metering’s regulated framework:
- Net metering provides the legal scaffold (mandatory bi-directional meter, mandatory retailer credit, mandatory annual settlement payout)
- Solar Club provides the rate (HI 35¢/kWh in summer when you’re a net exporter, LO 8.40¢/kWh in winter when you’re a net importer, switch automatically via RateSwitch since Feb 2026 bill runs)
- Both work simultaneously, and combined the household sees ~$1,000+ of additional annual benefit vs flat-rate retailer alternatives
This is the single biggest reason Alberta solar economics outperform provinces with bigger one-time rebates. See our Alberta solar rebates and incentives guide for the full provincial-vs-province comparison.
Selling your home with solar: what transfers
This is one of the most common questions during the buying process. The short answer: your solar system, the bi-directional meter, and the micro-generation interconnection agreement transfer with the property. The buyer inherits an active, producing system on day one.
What the seller should hand over at closing:
- Original installation contract (Stellar Upgrades or other installer)
- Equipment serial numbers (panels, microinverters, racking, battery if any)
- Manufacturer warranty registrations (LONGi 25-year + 30-year, APsystems DS3 25-year)
- Workmanship warranty paperwork from the installing entity
- Roof leak / leak-proof warranty paperwork
- Monitoring app credentials (APsystems EMA, EP Cube, Wallbox if applicable)
- Active interconnection agreement with EPCOR / FortisAlberta / ATCO / ENMAX
- Most recent 12 months of solar production data
- Any active CEIP financing balance (this is attached to the property tax bill and transfers automatically)
The retailer-side credit balance handling depends on the seller’s contract. Most retailers either cash out the credit balance at the time of sale (treating it as a final settlement) or transfer the closing balance to the buyer via mutual agreement. Read your retail contract before listing the home so you know which applies.
Independent appraisal data shows a typical Alberta solar installation adds approximately 70–80% of its install cost to home resale value (and that's before factoring in the value of an active CEIP financing transfer or active retailer credit balance). For a $30,000 system, that's $20,000–$24,000 of value — plus the buyer inherits all the future electricity savings and Solar Club enrollment. Solar systems are listed on every major Alberta real-estate listing platform now (Realtor.ca, MLS) under property features.
The application process: step by step
For a typical Edmonton install, the timeline runs:
Day 0 — Contract signed. Stellar enrolls customer in Pre-Solar Rate (7.25¢/kWh) the same day. Customer’s next bill drops immediately.
Days 1–14 — Engineering and applications. Stellar prepares electrical and structural engineering drawings, files the City of Edmonton building and electrical permits, files the EDTI / FortisAlberta / ATCO / ENMAX micro-generation application, and notifies the retailer of pending micro-generation enrollment.
Days 15–30 — Permits and approvals. City inspector reviews permits. Distribution company reviews micro-generation application. Both typically clear within 2–4 weeks. Stellar coordinates communication.
Days 30–45 — Physical installation. Stellar installs the system. In-house certified electricians, supervised by our Red Seal Master Electrician, never subcontracted. Most residential installs complete in 1–3 days on site.
Days 45–55 — Inspection. City of Edmonton (or relevant municipal authority) electrical inspector inspects the install. Stellar coordinates and meets the inspector on site.
Days 55–80 — Bi-directional meter swap and PTO. Distribution company schedules the meter swap. EPCOR runs about 4–6 weeks from install completion to meter activation. FortisAlberta’s PowerClerk-managed process can be faster. Once the bi-directional meter is live and Permission to Operate (PTO) is issued, the system is officially generating credits under net metering. Customer transitions from Pre-Solar Rate to standard Solar Club rate.
Total typical end-to-end timeline: 10–12 weeks from contract signature to producing under net metering.
Common net-metering mistakes (and how to avoid them)
Mistake 1: Sizing the system without using actual annual kWh consumption. “Estimated” sizing based on home square footage or heuristics tends to under-size. Pull 12 months of bills before the design conversation; we use the actual numbers, not estimates.
Mistake 2: Choosing a retailer that doesn’t support Solar Club without realizing it. Most do, but a handful of smaller retailers don’t. Verify before contract. The 15+ Solar Club retailers are listed in our Solar Club Alberta guide.
Mistake 3: Not reading the retailer contract’s settlement-rate fine print. Most retailers settle unused credits at retail rate (most generous) or wholesale equivalent (less generous). Read it before signing the retail contract.
Mistake 4: Assuming the bi-directional meter is included in the panel cost. It is — but only if your installer files the application. Cheaper installers sometimes leave this as “the homeowner’s responsibility.” Get it in writing.
Mistake 5: Forgetting to enroll in the Pre-Solar Rate at contract signing. 6–10 weeks of imports at 7.25¢ instead of 23¢ is real money. The Solar Club guide covers the Pre-Solar Rate mechanic.

Bottom line
Net metering is the regulatory foundation that makes Alberta solar work. It is mandatory across every retailer, governed by Alta Reg 27/2008, run by your distribution company at no extra cost, and pays out unused credits in cash at year-end. Combined with the Solar Club rate program, it produces 25-year economics that beat every other province in Canada despite Alberta’s smaller rebate landscape.
