Last Week a Mud Slide, yesterday Sky Train down (2nd time in as many weeks), BC Hydro Toppled Tower 49°13'6.70"N 122°49'35.98"W . What Next?

 UPDATE July 14, 2011   link below   Fire in Stadium-China Town Station


"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

The Lions Gate Bridge has this to stop marine vessels from bumping into its towers at the First Narrows.  Just how dense are the designers at BC Hydro for not realizing that Marine traffic, or barges, do have the potential to bringing down their hydro lines?


Memo to BC Hydro employees and BC Liberals:   Google Map and Google Earth photos are not in real time.   The photo above with, or without booms, prevent the towers from being damaged, whereas without booms around your hydro towers on the Fraser River, there IS a proven possibility.


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.

Mandatory Reliability in BC

In August 2003, a wide-spread blackout affecting central Canada and the eastern United States shook the electric utility industry.  Lasting several days and affecting an estimated 50 million people, the blackout led President Bush and Prime Minister Jean Chretien to establish a joint Canadian-US Task Force to review the incident.  The Task Force recommended that reliability standards be made mandatory and enforceable, with sanctions for non-compliance.
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.
