Ontario's Ontario Energy Board approved electricity rate increases pushing ultra-peak time-of-use prices to 39.1¢/kWh, making solar panels one of the most effective financial strategies for Ontario homeowners facing escalating hydro bills. Pairing a solar installation with battery storage allows households to discharge stored solar energy during ultra-peak pricing windows instead of drawing from the grid, eliminating the most expensive portion of their electricity consumption. Solar X helps Ontario homeowners model their bill savings under current and projected OEB rates before committing to a solar installation.

What Ontario's Latest Electricity Price Hike Means for You — and How to Stay Ahead

Ontario Electricity Price Hike

Ontario's Electricity Prices Continue to Skyrocket

Starting this month, electricity prices for households, small businesses, and farms will once again rise. Dictated by the Ontario Energy Board (OEB), rates are set to rise by up to 10%, with on-peak power now costing 20.3¢/kWh, and ultra-peak, the highest tier under Ontario's Ultra-Low Overnight plan, jumping to 39.1¢/kWh.

These increases reflect a broader trend across the province, with electricity costs steadily climbing — a trend that is unlikely to cool off anytime soon.

Driving this price increase is Ontario's growing demand for power, particularly as a result of economic growth, immigration, and growing electrification. At the same time, maintaining and upgrading Ontario's (and the rest of Canada's) aging grid is getting more expensive, with costs passed directly on to ratepayers through higher delivery and energy charges. Have a closer look at your next electricity bill, and you'll see exactly how much you're truly paying.

Simply put, the cost of electricity is rising, and that's a trend Ontarians can expect to continue.

That's not to say there isn't good news. The cost of solar energy and battery storage has fallen dramatically over the past decade, making it one of the most effective ways to protect yourself from future rate hikes. Once installed, solar panels let you generate your own clean electricity for half the cost or less of current grid power, and paired with storage, lets you save and use energy for when the rates peak or outages strike.

Take Control of your Power Bill

Instead of being at the mercy of the next price hike announcement, homeowners and businesses can lock in their own long-term energy stability and reduce their exposure to unpredictable grid costs.

As Ontario continues to grow as one of North America's most prominent urban centres, electricity prices will inevitably keep rising. But with solar and storage, you don't have to keep paying more for the same lifestyle. You can produce it yourself, sustainably, reliably, and for less money.

Frequently Asked Questions

How much are Ontario electricity prices increasing in 2026?

Ontario electricity prices have increased by up to 10%, with Ultra-Low Overnight rates at 3.9¢/kWh and on-peak rates reaching 39.1¢/kWh. The Ontario Energy Board (OEB) adjusts rates periodically, and rates are projected to continue rising 3–5% annually. Solar and battery storage lock in energy costs and protect against future rate hikes.

How can Ontario homeowners protect themselves from rising electricity rates?

Ontario homeowners can protect against rising hydro rates by installing solar panels (which generate free electricity for 25+ years), adding battery storage (to avoid on-peak rates of 39.1¢/kWh by charging at 3.9¢/kWh overnight), and enrolling in Ontario's net metering program to earn credits for surplus solar production.

What is Ontario's Ultra-Low Overnight electricity rate?

Ontario's Ultra-Low Overnight (ULO) rate is a time-of-use pricing tier of 3.9¢/kWh available overnight (11 PM–7 AM). This rate pairs powerfully with battery storage: charge your battery at 3.9¢/kWh overnight, then discharge it during on-peak hours when rates reach 39.1¢/kWh, saving up to 35.2¢ per kWh in arbitrage.

How quickly does solar pay back with Ontario's current electricity rates?

At current Ontario electricity rates (on-peak 39.1¢/kWh), solar systems can pay back in 7–10 years for typical residential installations. Combined with the Ontario Home Renovation Savings Program rebate (up to $5,000 for solar, $5,000 for battery), payback can drop to 5–8 years, with 15–20 years of free electricity following.
