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. The report said the Hornsea offshore windfarm shut down after experiencing an unusual voltage fluctuation “coincident with the lightning”. Review the CDC’s guidelines for “ Going to a Public Disaster Shelter During the COVID-19 Pandemic.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. Try to bring items that can help protect you and others in the cooling or warming center from COVID-19, such as two masks for each person age two or older in the household, hand sanitizer that contains at least 60 percent alcohol, and cleaning materials. Locations may have changed this year due to the COVID-19 pandemic. Check with your local officials for locations of cooling or warming centers. Sign up for email updates about coronavirus from the Centers for Disease Control and Prevention (CDC). Power may return with momentary surges or spikes that can cause damage. Turn off or disconnect appliances, equipment, or electronics. Never use a gas stovetop or oven to heat your home. Generators, camp stoves or charcoal grills should always be used outdoors and at least 20 feet away from windows. Install carbon monoxide detectors with battery backup in central locations on every level of your home. Throw out food if the temperature is 40 degrees or higher. A full freezer will keep the temperature for about 48 hours. The refrigerator will keep food cold for about four hours. Have enough nonperishable food and water. Keep freezers and refrigerators closed. Find out how long medication can be stored at higher temperatures and get specific guidance for any medications that are critical for life. Talk to your medical provider about a power outage plan for medical devices powered by electricity and refrigerated medicines. Determine whether your home phone will work in a power outage and how long battery backup will last. Have flashlights for every household member. Plan for batteries and other alternative power sources to meet your needs when the power goes out, such as a portable charger or power bank. Take an inventory of the items you need that rely on electricity. Leaders in Business Community Resilience.
