Understanding What You Use Helps to Conserve Reviewing Your Con Ed Bill

With the constant rise in energy costs, the use of “peak generating plants” and increased individual energy consumption, we are seeing a direct impact on our monthly electricity bill. According to Con Ed, July 2008 set a new record of 6.7 billion kilowatt hours, or approximately 350 kWh hours per customer. Going forward it will cost more and more to light, heat, cool, and live in our homes. What can we do to lower our bill, become more energy efficient in our homes and essentially become more “green”?

Rising energy costs are largely out of our control, but reducing energy consumption through conservation can offset these increasing costs and lower your energy bill. The most important step to conserving energy is to first understand the amount of energy you use and how you are being charged for it. Go and get your last few Con Edison bills to refer to as we go through how energy is used and charged. Con Ed’s electricity charges are divided into two parts; supply charges and delivery charges, with the details of each broken down on your bill. Don’t be afraid to call Con Ed to ask about rate increases or to clarify anything you don’t understand

I recently had cause to call them when my electricity bill increased by more than 50 Percent in just one month. According to the Con Ed customer representative, my increase was part of a 22 percent raise in energy costs from last year at this same time, normal augmented summer use (fans/AC), a jump in price of kilowatts per hour (kWh), and the $4.25 rise in delivery charges per household. All these factors are contributing to the fact that “total spending on both electricity and energy is at a record high,” according to Mark Zandi, chief economist at

Supply Charges

The supply charge is the cost for the energy you actually use. Electricity usage is measured by kilowatts per hour or kWh. One kWh will light a 100-watt bulb for 10 hours. Appliances list their respective wattage on them or use the US Department of Energy’s “Typical Wattages of Various Appliances,” found on their website, for average wattages and a formula to estimate energy consumption. Your kWh used multiplied by your rate constitutes your supply charges and are billed by an ESCO, (energy service company), who supplies electricity to customers. Traditionally, New Yorkers get electricity supplied and delivered by Con Ed, but you can choose to have another company supply your electricity.

The supply charge is also comprised of the merchant function charge, GRT (gross receipt tax) and other tax surcharges. The latter is basically a tax on a tax. The above combined with your usage makes up your total supply charges. The majority of supply charges are directly tied to usage, so as you conserve more energy you pay less.

  • Good article, concise and easy to understand. The writer has obviously done her homework.
  • This article fails to mention that at most the amount you would save on delivery charges by switching to an esco is about one dollar. I would not call that savings... The fact that con eds delivery charges are about double or triple the supply charges seems to indicate something very wrong...
  • I agree with the above comment. ConEd delivery charges are outragously high!!!! They are a monopoly, I just wished we had an alternative. Without them we will not get any gas or electricity, no matter which ESCO you choose. The savings by the way are definitely not worth it. You have to do so much work to find the lower one only to find out they raise their prices a few months after you join them!!! What a SCAM.
  • Those old natural gas pipes sure suck up a lot of "delivery charges." What a scam.
  • I agree with previous comments 100%. This is a scam. My gas and electric bill almost doubled for while. I never paid so much money in my life when I had an ESCO service. Con edison's pushing for this very much and people fall for it for a sake of saving a few bucks. Con edison is a Con artist!
  • The con Edison bill is too damn high especially for one bedroom..con Edison surcharge are likely higher then the regular monthly bills itself smh...and I don't see why...every month my bill is charge diff delivery KWH.under the basic services charge..need to get a lawyer smh is ridicious.and im a new tenants
  • When we have a several-day heat wave, Con Edison reduces our electric - sometimes by as much as 8%. I would like to know why they aren't required to reduce our electric bill by that same percentage. After all, we are having to pay for something we are not getting.
