This rate option is designed for greenhouse growers who use all or part of the electricity supplied by Hydro‑Québec for photosynthetic lighting or space heating to raise crops. More specifically, it targets customers who are able to adjust their production and to manage their electricity consumption in such a way as to reap the benefits of the Additional Electricity Option while working with the associated constraints.

This option applies to a Rate D, DP, DM, G, M, G9 or LG contract where some or all of the electricity is used for the purposes stated above and the maximum power demand has been at least 50 kilowatts (kW) during a consumption period included in the 12 consecutive monthly periods preceding the date of the sign-up request.
