About 15,000 residents had their power restored as of 6:30 a.m. local time, the governor said in a separate tweet. Eversource Energy, in charge of the recovery operation, expects work to be completed by mid-day.

As of 6:30 am all residences/buildings in the affected area were confirmed to be clear of natural gas. We’re actively working with National Grid to restore power, and anticipate having that completed by mid-day.

“Eversource has worked hard to coordinate this operation with Columbia Gas and National Grid, and National Grid has been a strong partner in coordinating the return of electricity,” Baker tweeted. Recovery efforts will now be focused on assessing the damage to the low-pressure gas system, and inspection of gas equipment at proprieties.

The Massachusetts governor declared a state of emergency on Thursday after explosions along a natural gas distribution system killed one person and injured more than 25 others.
