The greenhouse sector is one of the fastest-growing sources of electricity demand in Ontario, according to a report released October 10 by the Independent Electricity System Operator.
In Kingsville-Leamington alone, electricity demand is expected to increase by more than 200 per cent from 2018 to 2026, the report finds. Vegetable and fruit greenhouses are the largest driver of growth across the province, while cannabis is starting to have an impact as growers ramp up their operations.
Ontario’s greenhouse electricity consumption is forecast to increase 180 per cent to 3.9 TWh by 2024, up from 1.4 TWh in 2018, driven by expansion in the prime growing regions of Essex, Chatham-Kent, Norfolk and Niagara.
Electricity consumption related to cannabis is projected to increase 1,250 per cent over the next five years. This large increase reflects the fact that cannabis facilities were only producing product in 10 per cent of the 10.2 million square feet dedicated to cannabis growth in 2018. The remaining facility area is expected to be fully operational by 2023.
The IESO, with support from Enbridge Gas Inc. and the Ontario Greenhouse Vegetable Growers, collaborated with Ontario’s agriculture sector to produce the Greenhouse Energy Profile Study. The study summarizes how energy is used across sub-sectors and regions in 2018 and forecasts energy use and savings potential from 2019 to 2024.
In its report the IESO points to its Save on Energy Retrofit program, available through the IESO, as a way to help greenhouses better manage their energy use and reduce monthly electricity costs through incentives to upgrade various equipment and lighting.
The IESO is also inviting proposals through its Grid Innovation Fund from November 18 to February 14, 2020, for innovative indoor agricultural projects that have the potential to cost-effectively reduce electricity demand from facilities during local and provincial peak periods.
Community engagement is critical to understanding future electricity needs, and the IESO has been active in the Windsor-Essex region to ensure the electricity system is set to handle new growth. Earlier this year, the IESO requested Hydro One develop a new transmission line from Chatham to Leamington that will increase electricity supply to the area.
