Today's question: What is 'loss of generation'? Thanks to everyone who posed this question last night after yesterday's power outage. In the power business, a 'loss of generation' means something has happened that's caused one or more of our power generators to trip. When this happens, the amount of power we can generate and supply to the grid has decreased. In essence, the demand for power at that point in time is more than the amount of power that is available on the grid. The end result - a potential power outage to customers until we restart that generating unit(s) or one of our back-up generators. And in case you're wondering. The outage we experienced yesterday (09.19.19) was caused when one of the generating units at our Aishihik power plant tripped. When the unit tripped, we lost about 14 MW of power (about 30 per cent of the power that was needed by Yukoners connected to the grid at the time). Over the next few days, we'll be working to find out exactly why the generator at Aishihik tripped and to take the appropriate corrective action. Thank you all for your patience during the outage yesterday. We recognize that power outages do have an impact and appreciate your understanding.
On September 19, 2019, a trip at our Aishihik power plant caused a power outage that affected approximately 7,400 customers in communities across Yukon. The outage began at approximately 3:50 in the afternoon. By 6:10 yesterday evening, power was restored to all customers. Details about what caused the Aishihik power plant to trip are unknown. We're conducting a full review of the outage to determine why one of the generating units tripped and will take action to correct whatever is found to be the cause. We recognize that power outages have an impact on Yukoners and thank those affected by the outage yesterday for their patience and understanding.
