Over 240,000 people still remain without power, or 18% of customers, according to Eversource.
Hundreds of thousands of Connecticut residents remain without power nearly four days after Tropical Storm Isaias, which struck on Tuesday killing two people and leaving widespread damage across the state and entire towns in the dark.
The outages continue into a fourth full day as many try to work from home amid the ongoing coronavirus pandemic.
