Who is the speaker most probably?

Thank you for calling Blue Power. At the present time，we are experiencing electrical power outages in many residential neighborhoods on the south side of the city. It is believed that the stormy weather this evening caused the power station on Washington 200 Street to shut down. A team is on its way to assess and solve the problem. We currently estimate that power on the city’s south side will be back on by 7:00 a.m. If your power has not been restored by 9 a.m.，please call back to hear an updated status report. Thank you for your understanding.
