He said Siemens and GTR had set up a task force to analyse how their trains reacted, and to minimise the impact of any similar incidents in the future. Consumer New Zealands Paul Fuge said complacency about power outages is the downside of having a generally reliable system. Steve White, chief operating officer of GTR, said that “a drop in the frequency of the overhead line voltage during the National Grid power failure… triggered a safety mechanism on all operational Class 700 and Class 717 Siemens Desiro City trains which caused the trains to shut down, protecting the onboard systems and electronics.” National grid operator Transpower issued an alert to power companies just before 8am on Thursday, warning of a risk of insufficient generation and reserves to meet demand. In total, 371 services were cancelled and 873 delayed, although other train types were unaffected by the power issues. While around half of the 60 affected GTR trains were restarted by their drivers, the rest required engineers to be dispatched, blocking tracks and causing huge disruption on lines into London St Pancras and King’s Cross. The Class 700 and 717 trains, which have been introduced on Thameslink and Great Northern services over the last three years, shut down following the drop in frequency, although Network Rail’s overhead power line supply operated continually, according to the National Grid report. It’s important that the industry takes all possible steps to prevent this happening again.”Ī separate investigation is being conducted by Govia Thameslink Railway (GTR) and the manufacturer Siemens to discover why its new trains were so badly affected by the outage. “The power cuts of Friday 9 August caused interruptions to consumers’ energy and significant disruption to commuters. “This will ensure the industry learns the relevant lessons and clearly establish whether any firm breached their obligations to deliver secure power supplies to consumers,” he said. Jonathan Brearley, a senior executive at Ofgem, said the regulator had received the report and believed there were still areas that needed to be investigated. These off-grid generators are not visible to National Grid, which can only estimate the amount of electricity they add by noting a fall in demand for on-grid electricity when they run and a rise in demand when they shut off. In addition, the strike may have also triggered outages at a string of “embedded” generators – such as small-scale renewables and diesel farms – totalling an estimated 500MW. The combined power capacity lost in the twin outages was more than 1,300MW. National Grid had only 1,000MW in reserve as backup supply when the outages took place. If power cuts can happen when just two power generators drop off, then something fundamental has gone wrong.” Prof Dieter Helm, a government adviser on energy policy, said: “The key point is that the power cut should never have happened in the first place.
RWE, the owner of the gas plant, has warned that it is too soon to say whether lightning had any impact on its operations because investigations into the root cause of its outage are ongoing. A spokeswoman for Ørsted, the windfarm owner, declined to comment. There are several electricity network operators. The report said the Hornsea offshore windfarm shut down after experiencing an unusual voltage fluctuation “coincident with the lightning”. They are the people you should contact if you experience a power outage - no matter who you pay your bill to. "While I totally appreciate their need to make repairs, my priority is the comfort and safety of the people of our community," Perry said in his statement.The outages took place within seconds of each other immediately after the strike, according to the report, causing disruptions across much of England and Wales. If we do not make these repairs, there is a risk that your area will experience an unplanned. Why is this outage happening The electrical distribution system in your area is in need of repairs.
Frequently Asked Questions: Planned Power Outages -> If You Have Received Notice of a Planned Power Outage. "I am deeply disappointed with National Grid's decision to interrupt power at this time of the year with no advance notice to the City," Perry said. National Grid - Frequently Asked Questions. The mayor told the Eagle Tribune on Tuesday that he was never formally notified of the planned outage. The mayor opened an emergency shelter at Timony Grammar School Tuesday evening to accommodate people affected by the outage. "Winter seems like the most inappropriate time for 'planned' maintenance," Perry said in a statement. on Tuesday and was turned back on early Wednesday morning. National Grid planned to interrupt electrical service for up to 10 hours, according to a statement from Mayor Neil Perry. The mayor of Methuen, Massachusetts expressed disappointment in National Grid Wednesday after the utility conducted a planned electrical power outage overnight.
