It's been an especially warm fall on Long Island, but National Grid customers did not see a decrease in their natural gas bills in November due to the weather normalization adjustment.

The adjustment allows the utility to recoup some of its losses when it's not selling a lot of natural gas.

In addition to the weather normalization adjustment this winter, National Grid customers will also feel the effects of the second phase of a three-year rate increase.  All told, the average bill will go up by about 10 percent.

Some National Grid customers were not very happy about the adjustment.

"I think they're too high. Even though the economy is getting better, they're not getting that much better for me," said one customer.

In a statement, a spokesperson for National Grid said that "the average customer is still paying less on their total bill compared to the last two years for the month of October."
