National Grid says it is expecting a 29% increase in heating bills this winter.

The company says state-approved delivery price increases and continuing volatility in the natural gas market as reasons for the increase.

Hofstra University Associate Professor of Economics Martin Melkonian says natural gas is also getting scarcer because they were low on inventory at the beginning of the year.

The average customer who normally spends around $1,000 during the winter to heat their homes will be paying nearly $1,300 this winter.

Natural gas customers like Deice Acevedo are scrambling because of the coming price increases.

"Everybody's trying to cut cost because of inflation and it's like, 'Here we go, another thing to worry about,' but you know we're gonna have to see how much it goes up," Acevedo says.

The rest of the over 600,000 Long Islanders who heat their home through National Grid could see even higher costs depending on how cold the winter is.
