Two Long Island schools have filed suit against LIPA, PSEG and the state Department of Public Service, charging the utility engaged in a “pattern” of misclassifying customers in the wrong rate class and failing to refund years of overbilling. The filing by the Nesconset Elementary School and Great Hollow Middle School, both in the Smithtown school district, last month, followed reports in Newsday that more than 1,000 customers had been misclassified as large commercial customers even though their usage did not warrant it. Big commercial customers pay a $10 daily fee that smaller users don’t, among other differences.

It takes issue with the fact that LIPA and PSEG have awarded refunds to some wrongly classified customers but not others.
