Energy bosses caused disbelief by blaming power cuts that left thousands blacked out for more than a week on wind coming from the wrong direction.
Hundreds of homes and businesses were without electricity again yesterday in the wake of Storm Barra just as properties were finally reconnected 12 days after Storm Arwen.
The suggestion that Arwen’s north-easterly gales caused more damage than would be expected from the prevailing south-westerly wind stunned MPs, who said power networks should be ‘prepared for wind coming in multiple directions’.
Paul McGimpsey, of the Energy Networks Association, told the Commons business, energy and industrial strategy committee that the wind coming from the North East meant that in many cases ‘trees would fall differently on to the lines’.
Committee chairman Darren Jones expressed incredulity at the suggestion that networks might base plans on wind coming only ‘in a certain direction’.

Mr McGimpsey said this was not the case but wind direction was a ‘particular issue’ with Arwen.
Almost one million homes in the North of England, Wales and Scotland were blacked out after Arwen.
The last few hundred in north-east England were finally reconnected yesterday.
Three flood warnings were in place in England and five in Wales after Barra yesterday, but forecasters predict lighter winds and drier spells today.
Mr McGimpsey told MPs: ‘One of the particular issues we have faced with this storm which has been different to what we faced in the past – the wind direction coming from the north-east,’ he told MPs.
‘It is not prevailing winds that you would expect from the south and as such in some, many occasions, trees would fall differently onto the lines.’
Labour MP Darren Jones, chair of the committee, retorted: ‘Can I just check that I’m hearing this right?

‘We planned for resilience work on the basis that the wind would only come in a certain direction?’
Mr McGimpsey replied: ‘No, I’m not saying that.
‘I’m just saying that this storm has caused particular issues and the wind direction was one of those.’
He added that power firms had spent £730million on ‘resilience’ over the past five years, including flood defences and cutting down trees near electricity lines.
Mr Jones responded: ‘It does seem to me that we ought to be prepared for wind coming in multiple directions and £730million over that number of years doesn’t sound like a lot of investment from my perspective.’
Mr McGimpsey was citing a Met Office report which said the ‘unusual direction of the strongest winds’ may have been ‘an additional factor influencing the number of trees brought down’.
