Why a Stand-By Generator Is Your Ultimate Backup Power Solution During Summer Storms in Ontario

Picture this…

It’s 8 p.m. on a July Saturday. The barbecue smells amazing, string lights paint warm colours across the yard, and a friendly debate over hockey rivals is in full swing. Suddenly the neighbourhood streetlights snap off. Your guests gasp as every house on the block disappears into darkness—except yours. Your air-conditioner hums along, the patio playlist keeps spinning, and you casually point to the discreet Generac® unit beside the house. That’s the power of preparation, and it turns an anxious blackout into the best party story of the summer.

Summer should be carefree, yet in Ontario it’s also peak outage season. High heat drives record electricity demand, while violent windstorms, derechos and the tail ends of hurricanes add a cocktail of tree limbs, lightning strikes and grid failures. In the past 12 months alone:

• More than 165,000 Toronto Hydro customers lost power when a single transformer station tripped on July 16 2024.toronto.citynews.ca

• A late-April 2025 windstorm knocked power out across southwest, central and eastern Ontario, leaving tens of thousands in the dark.ctvnews.ca

• An early-spring ice storm this year caused over one million cumulative outages province-wide as crews replaced damaged poles and entire feeder lines.canada.constructconnect.com

Add in summer thunder-cells that form in minutes over the Great Lakes and you have a recipe for spoiled food, flooded basements and sleepless, sweltering nights.

1. Rising demand, shrinking margin

According to the Independent Electricity System Operator (IESO), Ontario’s grid is navigating “tight resource margins” through at least 2025 as critical generators undergo maintenance while demand keeps climbing.ieso.ca The biggest spike hits when heat waves send air-conditioners into overdrive—often right as solar generation begins to wane at sunset. That mismatch puts homes north of the GTA at the mercy of load-shedding or unplanned brownouts. A whole-home generator smooths out that volatility, automatically starting within seconds of a voltage dip so your indoor temperature and sensitive electronics never notice the hiccup.

2. Summer storms in Ontario are getting wilder

Climate scientists note that warmer lakes feed more severe thunderstorms. For homeowners that means hail the size of golf balls, 100 km/h gusts, and heavy rain that saturates tree roots. When power poles and branches fall, the average restoration time stretches from hours into days—especially in cottage country and rural suburbs where crews must drive kilometre-long concessions between calls. Hydro One’s April storm report listed over 50 broken poles in a single district.canada.constructconnect.com

A permanently installed generator is built for this abuse during summer storms in Ontario. Generac’s aluminum enclosures resist corrosion even when wind-driven debris chips away at the paint, and the engines are pressure-lubricated for long runtimes. Pair the unit with Mobile Link™ cellular monitoring and you’ll get text or app alerts on fuel levels and maintenance codes even if you’re away at the cottage.

3. Five ways a generator keeps summer on track

1. Air-Conditioning & De-humidification
   Heat waves aren’t just uncomfortable; Health Canada lists them as a top risk for seniors and children. Keeping the A/C compressor, furnace blower and basement de-humidifier running can literally save lives.

2. Food Safety & Backyard Parties
   Public Safety Canada recommends discarding perishable food after four hours above 4 °C. Skip the cooler shuffle; your fridge and chest freezer stay at safe temperatures while you keep grilling.

3. Sump Pumps & Pool Pumps
   Thunderstorms dump centimetres of rain in minutes. A failed sump pump floods a finished basement fast, and a stalled pool pump turns crystal water cloudy in a day. A genset prevents costly water damage.

4. Medical & Remote-Work Equipment
   Oxygen concentrators, CPAP machines and home offices powered by fibre modems all rely on stable voltage. True Power™ Technology on Generac units delivers <5 % total harmonic distortion—safe for laptops and life-support devices alike.

5. Security & Vacation Peace-of-Mind
   Motion lights, Wi-Fi cameras and smart-locks stay online while you’re away. Insurance providers may even offer premium reductions for homes equipped with an automatic backup power solution—worth asking your broker.

4. Why choose a Generac Backup Power Solution?

• Automatic Transfer Switch (ATS): Detects an outage, starts the engine and shifts your home to generator power in ~15 seconds.

• Fuel Flexibility: Most 13–24 kW air-cooled models sip 2.4–3.9 m³/h of natural gas at 50 % load—no messy refuelling.

• Quiet-Test™ Mode: Weekly self-tests run at lower RPM, cutting sound levels to ~60 dB so you won’t wake the neighbours.

• Local Expertise: Platinum Electrical Contractors has installed thousands of units across the province over 30 years, tailoring pad placement, clearances and gas sizing to each municipality’s code.

5. Sizing for summer loads

A professional load calculation considers locked-rotor amps of A/C compressors, well pumps, EV chargers and future upgrades such as hot-tubs. As a ball-park:

• 10–14 kW covers essentials plus a 3-tonne A/C.

• 18–22 kW keeps dual-zone HVAC, pool heater and most kitchen circuits alive.

• 26–40 kW is ideal for larger estates with heat-pumps, electric ranges or detached offices.

Platinum’s technicians perform free on-site consultations with clamp-meter readings to verify start-up loads. That ensures the generator isn’t undersized (leading to brownouts) or oversized (wasting fuel).

6. Installation best practices for a trouble-free summer

• Clearance: Maintain 46–91 cm (18-36 in) of side clearance and at least 50 cm behind the unit for airflow—exactly what you see in the photo above.

• Base & Anchoring: We pour a concrete pad or bolt an aluminum GenBase™ stand to compacted gravel, then connect flexible stainless fuel lines with drip-leg sediment traps as per TSSA regulations.

• Permits & ESA Inspection: Platinum handles the Electrical Safety Authority notification, municipal noise by-law checks and, if required, arborist reports for tree pruning near overhead lines.

• Remote Monitoring: The Mobile Link LTE accessory is pre-configured and linked to Platinum’s service dashboard so we receive diagnostic alerts 24/7.

7. Financing & seasonal incentives

Hydro interruptions don’t wait for paydays, which is why Platinum partners with Financeit® for 0 % for 12-month or low 9.99 % for 60-month plans (OAC). Until August 31 you can also claim up to $300 off select Generac Guardian models—ask our team for details or check the Promotions page on GeneratorExperts.ca.
