Hydro-Québec Faces Transformer Shortage Amid Major Expansion Plans
Hydro-Québec is experiencing a transformer shortage impacting its $50 billion expansion plan to add 5,000 kilometers of transmission lines by 2035. The global demand for transformers has surged due to the energy transition and high electricity consumption from data centers. Hydro-Québec has secured firm purchase agreements with manufacturers like Hitachi, which is investing $270 million to triple production capacity in Varennes. Despite these efforts, rising costs, partly due to tariffs on copper and aluminum, have led to significant budget overruns in recent projects.

Hydro-Québec is facing a shortage of transformers affecting its major $50 billion investment plan to expand its transmission network by 5,000 kilometers by 2035. This shortage is attributed to a global surge in demand driven by the energy transition and data centers' electricity needs.
To secure necessary transformers, Hydro-Québec has established firm purchase agreements with manufacturers including Hitachi, which is investing $270 million to enhance production in Varennes. However, rising costs of transformers, influenced by tariffs on materials, have resulted in significant budget overruns, including an additional $1 billion for projects aimed at exporting electricity to Boston and New York. The Régie de l'énergie has expressed concern over the rising costs of Hydro-Québec's expansion projects.
