Hilo automates your smart devices to help you save
Save up to 20% on your electricity bill this winter
Hilo works with Hydro-Québec's Rate Flex D, which helps you save money by offering lower electricity prices throughout the winter — except during peak demand events, when prices temporarily rise. That’s when Hilo steps in, automating your connected devices to reduce your household's electricity use and help you hold onto those savings.

Smarter energy use pays off
With Hilo and Rate Flex D, our customers save an average of $150* each winter.
Estimate my savings
*Average savings are based on actual consumption by Hilo customers who chose a smart heating solution, across all participation modes, connected devices, and home types. The average is based on estimated savings from the 2025–2026 season (data to be validated in summer 2026) for customers enrolled in Rate Flex D who participated throughout the entire season under a scenario of 84 hours or 21 peak demand events. The calculation is based on Rate Flex D prices in effect during that season. Potential savings represent the difference between Rate Flex D and Rate D (the base rate), before taxes.
Our mission: to improve the consumption and management of energy during winter peak periods to meet our increasing need for electricity.
-
reducing our future energy needs and avoiding or delaying financial investments in the power grid
-
increasing the electrification of sectors that depend on fossil fuels
-
reducing our imports of more expensive, less clean energy in winter
