Rough seas cause construction challenges at AltaGas export facility in B.C.
CALGARY — Rough seas have been posing challenges for AltaGas Ltd. as construction on its propane and butane export terminal on British Columbia’s north coast nears completion.
The Ridley Island Energy Export Facility, or REEF, is 85 per cent complete and on track to come online before the end of March 2027, the company said Thursday as it reported its second-quarter results.
REEF’s capital cost estimate has risen by 12 per cent to about $1.5 billion.
“While onshore execution has been ahead of plan, in-water construction has proven more challenging due to maritime conditions and weather delays,” chief executive Vern Yu told analysts on a conference call.
