Introduction

If you’re a Rate L customer who’s able to curtail your consumption at Hydro‑Québec’s request, you can save on your winter electricity bill.

With the Interruptible Electricity Options, you get credits in exchange for lowering your electricity consumption at Hydro‑Québec’s request.

These options were developed to help balance electricity supply and demand in Québec. By limiting your power consumption during the periods requested by Hydro-Québec, you help ensure a wiser use of our collective resources. In return, Hydro‑Québec pays you the equivalent of what it spends when it buys power on open markets.

Sign-up procedure

You must submit your request to Hydro‑Québec, indicating your proposed interruptible power, before October 1.

Your interruptible power must be at least 3,000 kW, or 20% of the maximum contract power over the last 12 consumption periods ending at the end of the consumption period that precedes October 1.
