A Queens civil court judge has allowed three separate lawsuits against the Long Island Power Authority and National Grid to proceed in cases where homeowners sued the power companies over electrical fires that broke out during Hurricane Sandy.

About 170 plaintiffs alleged their homes caught fire as a result of the companies’ decision not to shut off power on the Rockaway Peninsula in advance of the Oct. 29, 2012 storm. In complaints, they said fires broke out when floodwaters came into contact with electrical systems.
