Matt Cordaro, who is on the LIPA Board of Trustees, says he noticed on a financial statement that fuel costs increased by $32 million over what was already budgeted. He says LIPA had no plans to formally announce the rate increase.

In a statement, a LIPA spokesperson says the adjustment "primarily reflects natural gas price spikes experienced by all regional utilities over the last two months as a result of the unseasonably cold weather."

Customers can find the increase on their March bills on the line that says "fuel cost and power purchase."
