B-C's public utility says it has taken a series of actions since an investigation found a buildup of gases caused the explosion in an underground electrical vault in Vancouver last February.
B-C Hydro president Chris O'Riley called a news conference to apologize for the blast that injured two people, saying it should never have happened.
O'Riley says 14 vaults, including the one that exploded, had been identified as high risk in 2016 through the utility's own assessment.
The Crown-owned company says it has decommissioned the 13 other vaults that were identified, so they no longer present a risk.
