Summer vs Winter Energy Rates

Summer vs Winter Energy Rates: How to Get the Best Deal

Energy use varies by season and can affect your energy bill. How much it costs to produce energy also varies by season and can also affects your bills. Take the Summer months (June through September) for example, demand is at its highest costing us more to produce and for you to use. You can keep track of how much electricity you use by looking at the number of kilowatt hours on your utility bills.

Understanding Kilowatt Hours
Kilowatt hours (kWh) is simply the way to measure how much electricity you’ve used. A kWh equals the amount of energy you would use by keeping a 1,000-watt appliance running for one hour.

For example:

Watts Used Duration Used kWh
10 watt - LED Lightbulb 100 hours  1
50 watt - Laptop 20 hours 1
80 watt - TV
12 hours 1
100 watt Lightbulb  10 hours 1
1000 watt – Washing Machine 1 hour 1
3000 watt – Electric Dryer 20 minutes 1

See what appliances and devices consume the most kilowatt hours in your home.

Standard Rate Plans vs Time of Use Plans
With standard, or “flat” rate energy plans, you pay the same amount per kWh no matter what time of day you use it. With Time of Use (TOU) rate plans, electricity prices per kWh are lower during Off-Peak times of day with overnight Super Off Peak hours costing 40% less than on the standard rate plan. Off Peak hours account for 88% of the year.


What You Should Know About Seasonal Rates and Your Bills

On standard electric rates, delivery rates increase by 2.5 cents once a customer’s monthly energy usage exceeds 250 kWh. An average Long Island household uses ~600 kWh per month most of the year, and during the summer that monthly average usage increases to ~900 kWh. This seasonal increase translates to an additional ~$45 per month in excess charges on household energy bills during the summer months.

On TOU, rates per kWh don’t change based on a threshold of how much energy you use. Instead, rates vary based on when you use that energy–just like surge pricing for the LIRR or Uber. Yes, there is a Peak period when kWh charges are higher than standard, but that only happens during a few high-demand weekday hours.
