Day-night service class (SC8)

Day-night is a residential electric service class that offers lower electricity supply rates at nighttime compared to daytime.

If you use at least 1,000 kWh per month and can shift your usage to nighttime, you may benefit from Day‑night.

Day‑night service class rates and details
 

Your bill is composed of delivery and supply rates, plus taxes and surcharges.

Delivery rates are fixed and only change with Public Service Commission (PSC) approval. By contrast, supply prices in New York change often because they’re set by an open market and can be affected by a variety of factors, such as demand.

This means supply prices are typically higher during the daytime, and in winter and summer, when energy use is higher.

If we purchase supply on your behalf, we pass the cost on to you with no markup.

Historical supply rates (per kWh)

Here you’ll find our Day-night historical supply rates compared to our Standard ones. If you’re being supplied by an ESCO, please check directly with them.

Usually, daytime prices are higher than the Standard prices, while nighttime are lower.

However, we work to keep Standard supply prices more stable during times when people use more energy, such as very cold or hot months. Because of this, during those periods, nighttime supply rates can be higher than the Standard rate.

Frequently asked questions

Yes, if you consume at least 1,000 kWh per month. Give us a call at 800.572.1111 and we can work on that.

If you consume more than 35,000 kWh per year, our Time-of-use service class could also be a good choice for you.

The best way to check your energy use is to access Energy Manager. If you have a smart meter, you can see your usage down to the hour.

You must consume at least 1,000 kWh monthly to switch to Day-night.

While we can’t guarantee you’ll save on Day-night, your final costs will depend on three things: how much electricity you use, when you use it and market supply price.

You’re more likely to control costs if you shift most of your energy use to nighttime hours. Think about heavy-use appliances, like laundry, dishwashers, EV chargers and other large equipment.

You may also save on this service class, if you use energy during mild weather, since supply prices are usually lower during those periods.

However, keep in mind that we don’t control supply price. It varies based on the market.

Check your usage down to the hour with Energy Manager and our historical supply prices to make an informed decision about your service class.

The Standard service class uses a single daily supply price to calculate your monthly bill. The Day‑night option charges you different prices based on when you use electricity:
 

Daytime (Peak): 7 a.m. – 11:30 p.m. EST (8 a.m. – 12:30 a.m. Daylight Saving Time).

>Nighttime (Off-Peak): 11:30 p.m. – 7:00 a.m. EST (12:30 a.m. – 8 a.m. Daylight Saving Time).


For the Standard residential service class, we forecast energy demand to help smooth out price swings. As a result, during high‑usage months like January and July, customers usually see lower supply rates than they would if we didn’t take this approach—even though your bill may still be higher because you’re using more energy.

We don’t smooth prices for the Day‑night option. Instead, those rates follow real‑time market prices. This means Day‑night prices can change more often and vary more than Standard service prices.

Yes. However, it’s important to check if the chosen company offers a day-night supply price class.

If you get your electricity supply from a third‑party provider (sometimes called an ESCO), check with them to see if they offer separate day and night rates. Any savings will depend on your supplier’s pricing, since we pass those costs through to you without markups.
