Testing at the Labrador Island Link has been put on hold temporarily while Hydro officials investigate what caused LIL to reduce its power load during yesterday morning’s tests.
The incident caused a temporary power outage for approximately 58,000 customers across the island yesterday morning.
Rob Collett, vice president and NL system operator at Hydro Engineering, said the system successfully tested a 500 megawatt load in October and yesterday’s test included a 700 megawatt load. He said that while the software was working fine and handling the load, the protection system kicked in and he took the LIL offline.
They are now trying to determine what triggered the protection and monitoring system. The LIL test scheduled for next week is unlikely to take place.
He said a thorough investigation would first be carried out and only after that process has been completed would the company consider resuming testing.
The test is part of the final commissioning of the Labrador Island Link. It is not clear if testing will be completed by the end of the calendar year.
