Eversource will be conducting aerial surveys of high-voltage lines in southwest Connecticut today.  This is part of an ongoing effort to strengthen the power grid and increase reliability.  The inspection involves the use of a helicopter flying over Eversource’s transmission line corridors to check for any emerging vegetation issues that may threaten electric reliability.  Weather permitting, a blue and white helicopter will be flying in the rights of way in Norwalk, Redding, Westport, Wilton between 9am and 3pm.
