If you are a Rate L customer and can exercise some load-shaving capability at Hydro‑Québec’s request, these options offer a great opportunity for you to save money on your winter electricity bill.
With these interruptible electricity options for Rate L customers, Hydro‑Québec offers you credits in exchange for curtailing your electricity consumption at its 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 contribute to 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.
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.
