The LIPA board approved its time-of-day plan Wednesday, giving customers the option to switch from a flat rate to one that fluctuates depending on the time of day.

Peak hours would run customers the most amount of money. That would be weekdays from 3-7 p.m. and costs customers 38 cents per kilowatt hour.

All other hours would be considered off-peak.

"Super off-peak" hours would be further discounted. They occur from 10 p.m. to 6 a.m. and cost 20 per kilowatt hour.

Most customers currently pay a flat electricity rate of 25 cents per kilowatt hour.

LIPA CEO Tom Falcone says most customers would save a little bit of money under the new plan. He also hopes the plan will reduce carbon emissions and save them the need to build additional electric grid infrastructure.

Some residents like Dominque Tomlinson, of Hicksville, don't want to think about scaling back on electricity during hot summer months.

"If it's a really hot day and I want to keep my AC on, I don't want to think about it," Tomlinson says. "And I haven't had a problem with my LIPA bill, and I'll keep it that way."

If customers' electricity bill on the off-peak rate is higher than it would have been under the flat rate after a year, then LIPA says it will automatically refund the difference.

LIPA says it will not start the program until next year and that customers do not have to enroll in it.
