Richard Healey & ODT: Alarm after night of pole failures





Don't you sometimes wonder whose side Mayors are on? There is concern about low turnout for elections, smaller and smaller proportion of people bothering to vote. Could it be because of growing impressions that politicians, local and central government, have agendas so far removed from what ordinary people without money & influence need, the only time we matter is when our votes can put them into positions of power. Look carefully at the record of basic integrity of candidates, not what they say before an election.

For almost three years I've tried to talk to CODC mayor Tim Cadogen about the risk that Aurora Energy's incompetence poses to his community. He has refused to engage.
For almost three years I have predicted a doubling of line charges for the customers of Aurora Energy. More recently I have highlighted the fact that Tim Cadogen's constituents already pay around double the line charges of the people of Dunedin - and only slightly less than double the line charges of customers in the Wakatipu. Tim Cadogen refuses to engage.
A couple of nights ago this happens. Tim Cadogen refuses to engage.
Clearly I need to say this again. It should by now be obvious to everyone that Aurora Energy does not operate a safe and reliable network.
Under the leadership of Richard Fletcher and Steve Thompson, it's clear to me that it continues to demonstrate that it does not have the skills or understanding necessary to identify or remediate the most dangerous structures on its network. It continues to use pole testing systems which, clearly, do not work - and that doesn't just mean Deuar. It continues to "reinforce" poles without having a clue how that changes the ultimate limit state of those structures because it does not take into account the resultant foundation strength.
All of that will be gobbeldy gook to many of you, but it's important to state it in this way because when, as I believe it surely will, this appalling situation results in death or serious injury it will be necessary to show the pattern of behaviour followed by the board and it's managers.
You might have noticed in the past few months that I've backed off Aurora somewhat. That is not because I believe their performance has improved, in my view it certainly hasn't. I've been busy helping some very brave and determined people to try to get justice for 29 men killed in another workplace disaster.
God help me, I hope that I won't soon find myself in a similar position to the Pike families. If I do it will simply be because of the complete arrogance of the people involved in the Aurora debacle, but if I do - God help them too.

Alarm after night of pole failures

Four power poles in Alexandra fell down on one night this week, prompting the local community board to again demand answers from lines company Aurora.
The Vincent Community Board this week approved an urgent, ''last-minute'' motion from board member Russell Garbutt for board chairwoman Sharleen Stirling-Lindsay to write to Aurora ''to express our concern and disgust'' about the pole failures....

...Electricity was cut to 1900 households in the Alexandra and Omakau areas about 7pm on Monday after a high-voltage pole near the Alexandra netball courts fell during high winds.
Crews worked through the night and power was restored at 4.27am on Tuesday.
Three low-voltage poles at the quarry end of Clutha St also fell during the high winds overnight on Monday, cutting power to 90 customers in that area.
Power was restored at about 11am on Tuesday....

...But Mr Garbutt said at Tuesday's board meeting he was alarmed by the pole failures.
Mr Garbutt has led other previous questioning of Aurora, after three poles fell down in Alexandra in just over three months in 2017, and one in Clyde about a year later.
An Aurora delegation headed by chief executive Richard Fletcher subsequently gave presentations to the board and Central Otago District Council, earlier this year, after Mr Garbutt challenged Aurora on its pole testing regime, under-investment in the Central Otago region, failing network and lack of accountability.
The delegation outlined Aurora's increasing investment in the Otago network........https://www.odt.co.nz/regions/central-otago/alarm-after-night-pole-failures#comments

Were is workplace or health and safety. It is just criminal to being putting the public in such danger.
Three years after this train wreck started we have the latest in a frightening series of asset failures in Alexandra and STILL Tim Cadogen takes no action on behalf of his community. Even more galling, the customers in Alexandra are paying twice level of line charges as those payed by a typical consumer in Dunedin for the privilege of having these dangerous structures litter their streets.
This is not, and never had been, a simple story of . This is, and always has been, a story of chronic mismanagement.
How Aurora identifies which of its power poles are not up to standard regarding resistance to an acceptable wind speed. Waits for them to fall over. They need more than a SMACK for this!

Windy as, factual as, sang the Tui.

It never fails to amaze me how gullible people can be. Aurora seem to be suggesting that the four poles that fell in Alexandra were the victim of high winds.
Richard Fletcher's lack of background in powerline engineering might explain any ignorance on the topic but it seems to me that it wouldn't absolve him from seeking decent advice. So before you read the stupid, but predictable, excuses that I'm sure are coming you might like to consider this:
According to the Council owned weather station located at Molyneux Park in Alexandra, 500 metres away from Netball courts, the peak wind gust for the day was measured at 78.5 km/h = 22 m/s > 301 Pa (Historic Design load 850 Pa).
Let me put it as simply as possible for you Richard, the pole fell under loading that was a fraction over a third of the load it was designed to withstand.
The pole should have laughed at the gusts, instead it screamed all the way to the ground.
