BC Hydro electricity demand decline reflects COVID-19 impacts across British Columbia, with reduced industrial load, full reservoirs, strategic spilling, and potential rate increases, as hydropower plants adjust operations at Seven Mile, Revelstoke, and Site C.
What's Going On
A 10% COVID-19-driven drop in BC power use, prompting reservoir spilling, plant curtailment, and potential rate hikes.
Province-wide load down 10 percent; commercial sites hit hardest.
Reservoirs near capacity; controlled spills at Seven Mile and Revelstoke.
Excess spills can harm fish; crews balancing safety with ecosystem impacts.
Prolonged slump may lift future rates as BC Hydro recoups deferred costs.
Elecricity demand is down 10 per cent across British Columbia, an unprecedented decline in commercial electricity consumption sparked by the COVID-19 pandemic, according to a BC Hydro report.
Power demand across hotels, offices, recreational facilities and restaurants have dwindled as British Columbians self isolate, and bill relief for residents and businesses was introduced during this period.
The shortfall means there's a surplus of water in reservoirs across the province.
"This drop in load in addition to the spring snow melt is causing our reservoirs to reach near capacity, which could lead to environmental concerns, as well as public safety risks if we don't address the challenges now," said spokesperson Tanya Fish.
Crews will have to strategically spill reservoirs to keep them from overflowing, a process that can have negative impacts on downstream ecosystems. Excessive spilling can increase fish mortality rates.
Spilling is currently underway at the Seven Mile and Revelstoke reservoirs. In addition, several small plants have been shut down.
Site C and hydro rates
According to the report, titled Demand Dilemma, the decline could continue into April 2021 and drop by another two per cent, even as a regulator report alleged BC Hydro misled oversight bodies.
Major industry — forestry, mining and oil and gas — accounts for about 30 per cent of BC Hydro's overall electricity load. Energy demand from these customers has dropped by seven per cent since mid-March, while in Manitoba a Consumers Coalition has urged rejection of proposed rate increases.
BC Hydro says a prolonged drop in demand could have an impact on future rates, which could potentially go up as the power provider looks to recoup deferred operating costs and financial losses.
In Manitoba, Manitoba Hydro's debt has grown significantly, underscoring the financial risks utilities face during demand shocks.
Fish said the crown corporation still expects there to be increased demand in the long-term. She said construction of the Site C Dam is continuing as planned to support clean-energy generation in the province. There are currently nearly 1,000 workers on-site.
