"A June 11 BC Hydro discovers a tower supporting a 500-kilovolt transmission line on the south side of the Fraser River has been damaged, presumably by a barge or other river traffic. BC Hydro secures the tower and plans for repairs." - Vancouver Sun July 6, 2011
Yesterday's shut down of the Sky Train line wasn't the first time that it happened. Three three weeks ago a "bus bridge" was initiated between Waterfront Station and Broadway and Commercial because Sky Train operators lost track of a train in the tunnel, and here it is happening again, same tunnel.
Today's fire at the Stadium-China Town Station July 14, 2011 - Vancouver Sun
A year before the Olympics, BC Stadium had its roof ripped asunder because of a malfunction, a tear in the roofing material, which resulted in a make-shift repair to to get us through the 2010 Winter Olympics with a large sigh of relief. And now the Provincial government is bankrolling a new roof.
Is there a 25 year curse on our past infrastructures, ones that should have been cared for by the current bunch of provincial politicians instead of their billion(s) dollar spending spree on the Sea to Sky Highway and the Port Mann Bridge Projects and PPP3's?
Last year there was a mud slide near Oliver which resulted in 14 homes being damaged, if not destroyed. The highway was cut in two by the mud slide which created a Provincial Report card on other reservoirs that need caring for. What now, BC Hydro's placement of towers in rivers, not on banks adjacent to rivers, to be looked at via another Report?
Richmond, surrounded by dykes, is it at risk of flooding?
BC Hydro is a member of the North American Electric Reliability Council (NERC) and its regional reliability organization – the Western Electricity Coordinating Council (WECC). We plan and operate the transmission system in accordance with NERC and WECC standards.
NERC defines reliability as comprising both adequacy and security:
- Adequacy is the ability of the transmission system to supply the total amount of electricity required to meet the needs of its customers at all times, taking into account any scheduled and/or reasonably expected unscheduled outages of system elements.
- Security is the ability of the system to withstand any sudden disturbances such as an electric short circuit or an unanticipated loss of a system element.
We are currently leading a project on behalf of government to implement MRS standards in British Columbia and develop a compliance monitoring and enforcement framework for the province. Over the next few months, BC Hydro will be consulting with other B.C. utilities (e.g. FortisBC), Independent Power Producers and other industry participants to develop a better understanding of the implications of implementing MRS in B.C. and to get input into the options for compliance and enforcement.
