System Operating Orders

Our operating procedures enable the safe, reliable and efficient operation of the power system. We develop operating procedures in consideration of safety standards, industry reliability criteria, equipment capabilities and environmental obligations. We develop operating procedures using simulations of the power system.

Digital copies of the System Operating Orders are no longer available on our website. They can now be accessed via the BCRC Extranet website. If you do not have access to the BCRC Extranet, please email TDSO.Compliance@bchydro.com with your reasons for needing this information.
