Two New Mega-Dams on the Table: What BC's Power Surge Means for Industrial Land and Electrification Costs

Less than a year after the John Horgan Dam reached full capacity in August 2025, BC Hydro has confirmed early-stage exploration of two additional major hydroelectric sites. The first, "Site E," would sit on the Peace River roughly 60 kilometres east of the John Horgan Dam near the Alberta border, potentially generating 750 megawatts and 3,000 gigawatt-hours annually. The second proposal targets the Homathko River near Bute Inlet, about 250 kilometres northwest of Vancouver, envisioning up to four dams and three powerhouses with capacity between 500 and 900 megawatts. These projects emerge as the Crown corporation projects electricity demand will surge 20 per cent by 2030 and 50 per cent by 2050, with peak demand increasing 44 per cent on the coldest days, driven by population growth, industrial expansion, and the proliferation of artificial intelligence data centres.

The announcement marks a significant shift in energy planning, coming just months after the $16-billion John Horgan Dam—formerly Site C—became fully operational and was officially renamed in May 2026. Site E revives a concept cancelled in the early 1980s due to environmental opposition, while the Homathko proposal would extend hydro infrastructure into the Central Coast region with potential transmission lines reaching Williams Lake and Vancouver Island. BC Hydro emphasizes that no decisions have been made, noting such projects require decades from conception to completion. The utility is simultaneously pursuing a $36-billion grid expansion, wind and solar contracts, geothermal exploration at Meager Creek, and a $1-billion conservation initiative to delay infrastructure needs.
