New York ( CNN ) -- It has been more than two weeks since Superstorm Sandy hit the Northeast , yet many still remain without power . Two residents of New York 's Long Island are going to court declaring , in effect , they 've had enough . A lawsuit filed Tuesday by the two residents charges the area 's main electricity providers -- Long Island Power Authority ( LIPA ) and its partner National Grid -- committed `` gross negligence , breach of contract , and fraud , '' according to attorney Ken Mollins , who is representing the plaintiffs . Although the suit , which does not seeks specific damages but calls on the court to award `` a sum to be determined at trial , '' was filed by two individuals , Mollins entered the claim as a class-action , which would allow other residents to join as plaintiffs . `` This has the potential to be the biggest class-action lawsuit ever with possibly 1 million individuals joining , '' Mollins said . Red Cross donations top $ 130 million for Sandy relief . As of Tuesday night over 13,000 customers still remained in the dark , according to LIPA 's Storm Center . Mollins is seeking accountability from the utility companies and believes they did not properly prepare for Sandy . `` In the week before the storm they did nothing to prepare , '' said Mollins . `` They took no evasive action whatsoever . '' In response to inquiries from CNN about the suit , LIPA spokesman Mark Gross said , `` At this time we are focusing on completing restoration for our customers . '' National Grid , a multinational company based in the United Kingdom , responded with a statement saying its workers are focusing on completing restoration and that they `` continue to work with local officials and relief agencies to provide ongoing support to those communities and to be there for our customers . '' CNN Legal Analyst Paul Callan who has experience in class-action lawsuits , does not believe this will be an easy win for Long Island residents because they will have to prove that the utility companies were negligent in planning for the storm . Callan believes LIPA can easily state that the catastrophic event exceeded everybody 's expectations . `` Ultimately , it 's Mother Nature that bears the responsibility . '' Volunteers feed the still-powerless after Sandy . Long Island residents , meanwhile , echo the plaintiffs ' attorney in criticizing the power companies . `` LIPA had horrible , horrible communication , '' said Susan Parker , who was out of power for two full weeks . Parker , however , does n't believe she will participate in the class-action lawsuit . `` I feel very lucky that all I lost was my power , I just keep thinking priorities and what some other people have lost , '' she said . Long Island resident Mitch Gerson also believes LIPA failed to appropriately communicate with customers . `` There 's absolutely no question in my mind that LIPA did a terrible job . '' Gerson said . He and his family were displaced from their home for over 12 days , he said , adding that the difficulties from that situation will be a factor in deciding whether he and his family will join the lawsuit . The lawsuit , which was filed in state court , came the same day that New York Gov . Andrew Cuomo bluntly criticized LIPA and called for its overhaul at a press conference . `` LIPA has been beyond repair for a long , long time , '' Cuomo said on Tuesday , `` I believe it needs to be overhauled and you need a new system . '' In the midst of heavy criticism for the company , the chief operating officer of Long Island Power Authority , Mike Hervey , announced his resignation on Tuesday , effective at the end of 2012 , according to a statement from LIPA .
More than 13,000 customers are still without power on Long Island , a utility says . Two Long Island residents are suing utilities after no electricity for days in the wake of Sandy . The plaintiffs ' attorney hopes other residents will join in the suit as a class action . The power companies say their focus continues to be on restoring electricity .
