We’re not sure we understand your question. If you are referring to the resilience of our network, don’t worry. Over recent decades, Hydro-Québec has continuously invested in and improved its system to increase robustness and its ability to neutralize the effects of geomagnetic disturbance (GMD) events related to solar storms.
Hydro-Québec very successfully managed the major solar storm that shook the earth’s magnetic field on June 22, 2015. [In French only]
We therefore protect our equipment against variations in the earth’s magnetic field caused by solar storms. As for the sub-atomic particles that reach earth from space, they have no impact on our system.
