Equipment Advisory – HVGB gas turbine offline for annual maintenance

Newfoundland and Labrador Hydro (Hydro) is advising that the gas turbine in Happy Valley- Goose Bay has been removed from service to complete annual maintenance.

The gas turbine, which is used for back up generation, will be removed from service until May 15 to replace an alternator shaft. There is no anticipated impact to customers as a result of this work.

Hydro’s annual maintenance season generally begins in April when customer electricity demand begins to decline and extends to November in preparation for the winter months.

During this time, Hydro maintains, replaces, and upgrades electricity equipment throughout the province. This includes preventative and corrective maintenance work and inspections, as well as larger capital projects.

Generation units and transmission lines will be removed from service for periods of time in order to complete the work. These yearly planned outages are closely monitored and coordinated to ensure customer supply and system reserve requirements are met.

Hydro’s maintenance program is part of the Company’s mandate to invest in the province’s electricity system to ensure delivery of safe and reliable electricity for customers. All major equipment advisories will be posted on our website here.
