BOSTON, Massachusetts Thousands of people were left without power in parts of Boston on Monday morning. Over 10,000 customers were without power at one point, though electricity had been restored to everyone as of 8 a.m. The outages appeared to be pretty widespread, with some traffic lights dark. Most of the outages appeared to be Eversource customers. Eversource initially said the outage was due to an underground equipment issue that happened just before 6 a.m., impacting about 10,000 customers. They said around 7 a.m. that they had restored power to about 3,000 customers and their crews were on site in South Boston working to restore power to the remaining customers. All customers had their power back as of 8 a.m., Eversource said. The power company also said that after further assessment, the cause of the outage was an issue at the Andrew Square substation. https://www.nbcboston.com/news/local/thousands-of-customers-without-power-in-boston-due-to-underground-equipment-issue/3958073/?amp=1
