Newfoundland and Labrador Hydro has released findings of investigations into problems with the Labrador Island Link last winter.

The link, or LIL, has been famously plagued by software issues that repeatedly delayed final commissioning of the entire Muskrat Falls Project until this past spring.

But testing last winter exposed other issues, most if not all of them having to do with the resilience, or lack thereof, of the on-the-ground infrastructure such as towers, lines and other equipment in harsh weather conditions.

In short, almost $30 million will be spent over the next several years to monitor and make changes that Hydro CEO Jennifer Williams insists could not be predicted or planned for, adding issues found were normal for a project of this size.

But she also told media that while the LIL continues to run reliably in the range of 700 megawatts, they’re putting off a max test up to 900 until the end of the winter. That’s because the extra power’s not needed right now, and it could be an unnecessary risk to the system, and residents, at a time when heat and light is needed most.

Meanwhile, Hydro continues to “catch up” on deliveries owed to Nova Scotia utility Emera, which was also affected by delays with the LIL.

Otherwise, Williams said crews are gearing up for another challenge this winter, but for now with no supply concerns.
