A sharp drop in temperatures across the province in recent days pushed FortisBC's gas and electricity systems to their highest energy demand of the winter season, with the gas system delivering approximately 19,523 megawatts (MW) of power and the electricity system delivering 739 MW.
British Columbians relied heavily on the gas system during this cold period, FortisBC reported Thursday, which saw temperatures dip below -4 C in the Lower Mainland and around -12 C in Kelowna.
In the Trail area, temperatures ranged from -19 C to -5.3 C during the cold snap, with Feb. 13 marking the coldest day at -19 C.
Other municipalities in the West Kootenay, such as Nakusp, experienced lows of -16.7 C and highs of 3.3 C reflecting the widespread chill across the region.
According to FortisBC, the electricity system reached its peak demand on Feb. 11, delivering 739 MW.
During peak demand on Feb. 12, FortisBC's gas system delivered approximately 70 terajoules of energy, equivalent to 19,523 MW of power.
"The cold weather we are experiencing this week serves as a crucial reminder of the importance of having resilient, reliable and flexible energy systems, capable of meeting high demand," said Joe Mazza, vice president of energy supply and resource development, FortisBC.
"By using the strengths of both the gas and electricity systems, we can ensure that customers have the energy they need when they need it most."
Mazza emphasized the critical role of the gas system during peak periods, noting its ability to store and quickly supply large quantities of energy, complementing the electricity system when demand spikes.
He also highlighted the potential for the gas infrastructure to carry renewable and low-carbon gases, such as Renewable Natural Gas, which can reduce emissions while ensuring reliable energy delivery.
On the coldest days of the year, energy usage can increase by up to 160 per cent compared to average winter days, as heating systems work harder to maintain comfortable indoor temperatures.
