Storm Betty’s Forecast Threatens UK Power Cuts

This morning the Met Office in Exeter issued a warning of high winds due to the imminent arrival of Storm Betty, the second named storm of this tempestuous summer!

According to the press release:

Met Éireann have named Storm Betty as a low-pressure system which is also triggering Met Office warnings…

A Met Office yellow warning for wind covers coastal areas of western Wales, eastern Northern Ireland and parts of northwest England and southwest Scotland. Rain warnings have also been issued from late Friday and into Saturday for Northern Ireland and parts of Scotland.

According to the yellow warning for wind:

Power cuts may occur, with the potential to affect other services, such as mobile phone coverage

In such circumstances I have a penchant for recording “baseline” images of the UK’s distribution network operators’ power cut maps. I was rather surprised to discover that Northern Powergrid’s looked like this earlier today:

Zooming in on the map, it seems many of those alleged power outages have been “scheduled” in advance, some of which remain on the map despite having already been cancelled for today.

It remains to be seen how many “unscheduled” additions Storm Betty leaves in her wake.

[Update – August 18th 20:30]

The predicted “unscheduled” power cuts due to the passage of #StormBetty across the British Isles have begun.

Here are the current power outage maps of ESB Networks in Eire:

and National Grid in South West England:

[Update – August 18th 23:00]

It is clear tonight that inhabitants of Ireland are feeling the effects of Storm Betty far more than us here in South West England:

[Update – August 19th]

This morning National Grid’s power cut map doesn’t look significantly different to an average day:

Unfortunately the same cannot be said of the ESB Networks map:

or the NIE Networks map for that matter:

At 11:50 AM ESB Networks issued a press release:

Storm force winds associated with Storm Betty caused damage to the electricity network overnight affecting just over 70,000 homes, farms and businesses at the peak. As at 11.30am, just under 50,000 electricity customers remain without power with the damage mainly attributable to lightning and fallen trees on overhead lines as a result of the high winds.

Areas most impacted include counties in the South-East along with North Dublin, Dundalk, Portlaoise and Kilkenny.

All available resources are being deployed to respond to all electricity outages where safe to do so. ESB Networks crews have been working since first light and will work through this afternoon into this evening to restore power to as many customers as possible. A significant number of impacted customers will have their power restored by this evening. However, due to the scale of the damage to the electricity network, some customers in localised areas may remain without supply overnight.

To be continued…

Storm Barra Barrels Towards Britain

As we anticipated yesterday, Storm Barra has been officially named by Met Éireann even though the remaining power cuts due to Storm Arwen have yet to be repaired:

Here is the Met Office’s current high wind warning for Tuesday:

and here is the current GFS wind gust forecast for early Wednesday morning:

We anticipate more power cuts across Ireland as well as here in Cornwall and further afield across the United Kingdom.

Here is ESB Networks’ view of the calm before Storm Barra:

Storm Brian Power Cuts

Less than a week after ex Hurricane Ophelia battered Ireland another named storm is due to arrive overnight. This one is more conventional than Ophelia, since Brian never was a Hurricane. However despite that he still packs a considerable punch. This time around Met Éireann have issued an orange wind warning for coastal areas in the south of Ireland:

Wind Warning for Coasts of Mayo, Galway, Clare, Kerry, Cork, Waterford and Wexford

Southeast winds of mean speeds 55 to 65km/h with gusts of 90 to 110km/h, will veer west or northwest and strengthen further during the night, reaching orange level with mean speeds of 65-80 km/h with gusts 110-130 km/h. Winds will ease to yellow warning level during Saturday evening.

Issued: Friday 20 October 2017 12:16
Valid: Friday 20 October 2017 22:00 to Saturday 21 October 2017 22:00

Meanwhile the UK’s Met Office has issued a yellow wind warning across much of southern England:

Brian-20171019+2d

A swathe of strong south or southwesterly winds reaching parts of Wales and southwest England will steadily transfer east and north during the morning. Later in the afternoon winds will gradually turn westerly and wind inland will start to slowly ease. Meanwhile, in western and southern coastal areas winds will start to slowly ease later in the evening. Gusts of 45 to 55 mph are expected widely within the warning area with gusts of 60 to 70 mph along exposed southern and western coastal areas. These are expected to coincide with high tides, leading to locally dangerous conditions around coastal areas in western and southern parts of England and Wales.

The local surf forecast for North Cornwall from Magic Seaweed reveals even bigger waves than Ophelia produced:

WidemouthSurf-20171020+1d

Meanwhile according to ESB Networks:

ESB Networks have now continued to restore power this morning, with power now restored to 343,000 families, farms and businesses. Approximately 42,000 customers remain without supply.

​The worst impacted areas are in the environs of Enniscorthy, Wexford town, New Ross, Bandon, Dunmanway and Fermoy.

Assisted by contractors, crews from Northern Ireland and overseas utilities, as well as the army and air corps, ESB Networks will continue restorations to every last family, farm and business until their lives are back to normal.

A Met Éireann Status Orange wind warning has been issued for seven coastal counties, including Cork and Wexford, will hamper restoration efforts. Should the weather conditions worsen further, our crews will be stood down until it is safe to resume repairs again. Winds speeds up to 130 km/h will cause outages to customers in Mayo, Galway, Clare, Kerry, Cork, Waterford and Wexford on Saturday.

 

[Edit – October 21st 10:00]

This morning ESB Networks have released a power cut heat map revealing how far their restoration efforts after Storm Ophelia managed to get before Storm Brian arrived:

ESB Networks have now restored ​363,000 homes, farms and businesses who lost power supply due to the damage inflicted by ex-hurricane Ophelia. Our crews are continuing to work to restore the 22,000 homes, farms and business that are still without supply.

The locations of these homes, farms and businesses are highlighted on the heat map below.

ophelia-heat-map-20171021-0900

Our crews will work to restore everyone as long as it is safe to do so. We are acutely aware of how difficult the situation is for all of customers who remain without power.

Power cut numbers are now rising again. By our reckoning there are currently just under 30,000 “homes, farms and businesses” without power across southern Ireland.

In this morning’s update ESB Networks report that:

While Storm Brian hampered power restoration following Storm Ophelia and caused additional outages on the system, work continued as and when safe to do so.

10,000 homes, farms and business remain without power this morning, down from 385,000 at the peak on Monday. Whilst Storm Brian caused additional problems good progress was made and the total number without power this morning is now 10,000.

[Edit – October 22nd PM]

This evening ESB Networks report that:

ESB Networks continue to restore electricity supply in the worst impacted areas of Counties Cork and Wexford. Approximately 6,000 customers are currently without power, a number of which are due to Storm Brian.

Here is an illustration of the remaining homes, farms and businesses that we are working to restore.

Hurricane Ophelia Power Cuts

Hurricane Ophelia is heading in our direction. Reaching category 3 strength earlier today she is the strongest hurricane on record this far east in the North Atlantic. Moving further north over cooler waters her maximum wind speeds have now reduced to category 2. By the time she gets here she will have morphed into an extratropical cyclone, but she’ll still be packing hurricane force winds. Here is the current forecast from the United States’ National Hurricane Center:

ophelia_5day_cone_20171015-15Z

ophelia_wind-prob_20171015-15Z

Met Éireann have issued a red wind warning across the south of Ireland:

Wind Warning for Wexford, Galway, Mayo, Clare, Cork, Kerry, Limerick and Waterford

Hurricane Ophelia is expected to transition to a post tropical storm as it approaches our shores on Monday bringing severe winds and stormy conditions . Mean wind speeds in excess of 80 km/h and gusts in excess of 130km/h are expected, potentially causing structural damage and disruption, with dangerous marine conditions due to high seas and potential flooding.

Here’s the Met Office’s warning of an amber alert for Northern Ireland tomorrow, together with a yellow wind warning for us here in Cornwall:

It definitely sounds blustery outside! Western Power Distribution’s power cut map doesn’t display anything too unusual yet:

WPD-Map-2017-10-16_0721

However a few power cuts have started appearing on ESB Networks’ map of Southern Ireland:

ESB-Map-2017-10-16_0824

 

[Edit – October 16th 11:00]

Over 35,000 properties are now without power across southern Ireland:

The lights are starting to go out here in South West England too:

WPD-Map-20171016-1053

The waves are getting bigger too:

[Edit – October 16th 16:00]

The ESB Networks power cut map seems to have given up under the strain. At 14:00 it showed over 180,000 properties without power. Meanwhile the storm has been bringing down power lines in Northern Ireland:

NIE-Map-2017-10-16_1613

and Wales:

WPD-Map-2017-10-16_1613

There are now a total of ~3500 properties without power across Western Power Distribution’s four areas of the country. Here’s how our local surf spot looks at the moment:

[Edit – October 17th 11:00]

Here’s a selection of reports about Ophelia from the media, together with this morning’s set of power cut maps:

ESB-Map-20171017-1012

NIE-Map-20171017-1012

Engineers from Electricity North West are working in difficult conditions today to restore power after ex-hurricane Ophelia hit the North West overnight.

The region’s power network operator has restored supplies to more than 16,000 properties throughout the night following the Met Office’s yellow weather warning for severe gales of 60 to 65mph.

Around 2,000 properties remain without power as flying debris has hit power lines and high winds make access difficult for repair teams. Properties are affected mainly in the Lake District with 1,700 without power and 150 properties in Lancashire are currently without power.

ENW-Map-20171017-1025

As a result of the high winds brought by the remnants of Storm Ophelia, whilst a number of customers have had their electricity supplies affected, the level of power cuts is considered busy but not exceptionally so.

The biggest impact has been in West Wales and Cornwall where a number of weather related incidents have occurred.

Currently around 3,000 customers are off supply. All incidents are currently being worked on by our engineers, with supplies on track to be restored this evening.

Since around 9am this morning we have restored around 12,000 customers in the South West and South Wales.

WPD-Map-20171017-1025

According to ESB Networks:

We are advising all customers impacted by outages that they should prepare to be without electricity for number of days. It is very important that any customers who use electrically powered medical devices should contact their healthcare professional to make alternative arrangements if necessary.

According to the Irish Times:

The country is facing days of “catch-up” as schools, hospitals, roads, electricity networks and other key public infrastructure are cleared of debris or repaired following Storm Ophelia.

Three people were killed on Monday in the worst storm to hit Ireland in more than 50 years, which left hundreds of thousands without electricity overnight.

The storm caused the most devastation in the south and west but left every county with some level of disruption.

Ministers and senior officials have warned that it will take days for some public services to get back to full strength. All schools will remain closed on Tuesday to allow for safety inspections to take place, with most expected to reopen on Wednesday.

 

[Edit – October 18th]

ESB Networks report that:

The following map shows the remaining faults caused by ex-hurricane Ophelia to be repaired. We have restored over 70% of homes and businesses and here are currently 105,000 homes and businesses still without power that are represented on the following map by the black circles. The bigger the circles the more faults there are that need to be repaired in that area.

ophelia-heat-map-20171018

Electricity North West have now repaired almost all the faults caused by Ophelia:

Engineers from Electricity North West have worked tirelessly to repair damage caused by ex-hurricane Ophelia and subsequent bad weather and restore power to the majority of customers in the region.

Despite working round the clock to restore power to those affected by ex-hurricane Ophelia on Monday and early Tuesday, further bad weather last night from 6.30pm caused power cuts to another 5,000 properties along the county’s west coast.

Engineers worked through the night and restored power to all but 18 customers and they will continue to work today to restore those final few customers located in Egremont, Cumbria.

Electricity North West has turned their attention to assisting the restoration efforts in the Republic of Ireland. A team of more than 30, including engineers and overhead lines people, will help repair damage and restore power to thousands still without power in the Republic of Ireland.

 

[Edit – October 19th]

ESB Networks have produced another power cut heat map. This evening they say that:

ESB Networks have now restored power to 322,000 homes, farms and businesses affected by ex-hurricane Ophelia. The following map illustrates the ​63,000 homes and businesses that we are currently working to restore.

ophelia-heat-map-20171019

 

[Edit – October 20th]

Here’s the latest power cut heat map from ESB Networks:

42,000 homes, farms and businesses remain without power this morning. These are highlighted in the following heat map.

ophelia-heat-map-20171020

The rate of progress numbers wise from here will slow down as each individual fault must be repaired pole by pole. Also with the weather forecast to worsen the conditions that the crews are working in makes the restoration effort more difficult and slower.

In a later news release they report that:

ESB Networks have now continued to restore power this morning, with power now restored to 343,000 families, farms and businesses. Approximately 42,000 customers remain without supply.

​The worst impacted areas are in the environs of Enniscorthy, Wexford town, New Ross, Bandon, Dunmanway and Fermoy.

Assisted by contractors, crews from Northern Ireland and overseas utilities, as well as the army and air corps, ESB Networks will continue restorations to every last family, farm and business until their lives are back to normal.

A Met Éireann Status Orange wind warning has been issued for seven coastal counties, including Cork and Wexford, will hamper restoration efforts. Should the weather conditions worsen further, our crews will be stood down until it is safe to resume repairs again. Winds speeds up to 130 km/h will cause outages to customers in Mayo, Galway, Clare, Kerry, Cork, Waterford and Wexford on Saturday.
