How much can I save with solar in Calgary under ENMAX net metering?

At typical residential rates (~13–16¢/kWh), a 10 kW solar system in Calgary (averaging 1,100–1,200 kWh/kW annually) generates $1,400–$1,900 in annual RoLR credits. Over 25 years and accounting for rising electricity rates, total savings exceed $50K. Federal 30% ITC reduces upfront costs by ~$10K.

What is RoLR and how are solar credits valued?

Rider on Loss and Risk (RoLR) is the rate ENMAX applies to solar export credits — approximately 1.5–2.5¢/kWh. This is significantly lower than your retail rate (~13–16¢/kWh). To maximize savings, size your system to match annual consumption, not maximize export.

What is the difference between RoLR and my retail electricity rate?

Your retail rate (~13–16¢/kWh) is what you pay to draw electricity from the grid. Your RoLR rate (~1.5–2.5¢/kWh) is what ENMAX credits you for exports. This gap incentivizes self-consumption via battery or load shifting to daylight hours.

Can I apply for ENMAX net metering online?

Yes. Applications are submitted through ENMAX's online portal after initial inquiry. Requires system design, equipment specs, and single-line diagram. Processing typically takes 6–12 weeks.

Does ENMAX install the bidirectional meter at no cost?

ENMAX typically covers meter installation costs for residential systems under 10 kW. However, any required grid upgrades are customer's responsibility. Confirm costs upfront with your installer and ENMAX.

Can I pair battery storage with my ENMAX solar system?

Yes. Battery storage is permitted under ENMAX net metering, allowing you to store midday solar for evening use. This improves economics by capturing excess generation and avoiding peak evening rates.

What Is ENMAX?

ENMAX is a regulated utility serving approximately 600,000 customers in Calgary and Southern Alberta, including Airdrie, Cochrane, and surrounding areas. ENMAX generates, transmits, and distributes electricity and is regulated by the Alberta Utilities Commission (AUC).

ENMAX has embraced distributed solar generation through its net metering program, which has seen steady growth among residential and small commercial customers. The utility's renewable energy strategy includes supporting customer-owned solar as part of Alberta's clean energy transition.

ENMAX Electricity Rates (2026)

Standard Residential Rate

Energy Charge~13.0–14.5¢/kWh

Distribution Charge~2.8–3.5¢/kWh

Transmission Charge~0.8–1.2¢/kWh

Rates vary by transmission zone and are subject to AUC approval. Verify current rates at enmax.com.

RoLR Credit Rate (Net Metering Export)

The Rider on Loss and Risk (RoLR) is ENMAX's rate for crediting your solar exports:

~1.5–2.5¢/kWh

RoLR is intentionally lower than retail to reflect avoided distribution losses and ENMAX's wholesale costs. Right-size your system to minimize export and maximize self-consumption.

Budget Billing Plan

ENMAX offers levelized monthly billing based on your average annual consumption. Solar reduces your billed amount; credits offset future consumption.

ENMAX rates are among the lowest in Canada. Current rates and schedule details: ENMAX Residential Rates →

ENMAX Net Metering Program

How Credits Work

• Solar generation tracked by bidirectional smart meter
• Export credits valued at RoLR rate (~1.5–2.5¢/kWh)
• Credits roll forward month-to-month
• Unused credits at year-end are forfeited (no cash payment)
• System capacity up to 100 kW

Right-Sizing Your System

Most Calgary homes consume 12,000–15,000 kWh/year. A 10–12 kW system (solar capacity) will approximate annual consumption at ~1,100–1,200 kWh/kW production. This maximizes credit utilization and minimizes forfeiture.

Battery Storage & Load Shifting

Pair battery storage with solar to capture excess generation and discharge during evening peak hours, further improving economics. Smart thermostats, EV charging during daylight, and pool pumps also optimize self-consumption.

Key Limitation: No Cash Payment

Unlike some utilities that pay cash for surplus solar exports, ENMAX's net metering program does not provide cash buyback. Credits expire at year-end. This makes right-sizing critical.

Solar Potential in Southern Alberta

Southern Alberta, including Calgary, has excellent solar irradiance due to high sunshine hours and low cloud cover. Calgary ranks among Canada's sunniest major cities.

Region	Irradiance	kWh/kW Annual
Calgary	Excellent	1,100–1,200
Red Deer	Excellent	1,080–1,180
Airdrie	Excellent	1,120–1,220
Cochrane	Excellent	1,150–1,250
Southern AB Foothills	Very Good	1,050–1,150
