WESTPORT - A public hearing was held in Westport tonight to discuss the preparation and response of Connecticut's electric and gas companies following Hurricane Sandy.

The Connecticut Public Utilities Regulatory Authority (PURA) has launched an investigation into the utility companies. A law was also passed just after the storm hit, requiring PURA to review the utility companies' performance whenever more than 10 percent of their customers are without power for more than 48 hours.

United Illuminating and Connecticut Light and Power reportedly had more than a million of their 1.5 million customers lose power at some point during Hurricane Sandy. Area residents affected by the outage say the companies can do better.

PURA says a typical investigation includes emergency planning, preparation for the storm, restoration performance, as well as other storm-related issues.

PURA will hold another public meeting in Waterford on Jan. 15.
