Connecticut Light and Power said Friday that it plans to seek a 5.9 percent rate increase from state regulators as it works to replace aging infrastructure and improve reliability.
The state's largest utility, which has about 1.2 million customers -- including those in Westport -- said any approved electric rate increase would not go into effect until December.
Under the proposal, customers using an average of 700 kilowatt-hours of power a month would see their bills rise by $6.76.
The power company says it is investing in new and stronger poles, wires, transformers and substations, which it says will result in fewer outages.
"Already, CL&P customers are seeing fewer and shorter power outages, as the system performed at its highest level in 2013 since the year 2000," the company said in a statement.
"Connecticut's electric rates remain extremely high," he said. "My office will participate in this proceeding, and I will urge PURA to approve rates that are no more than just and reasonable, as required by law."
