The data in this graph comes from a Con Edison residential customer with a billing period that runs from Dec. 30 to Jan. 30. It shows the customer’s per-kilowatt-hour supply charges, which cover the cost of generating electricity.
Spiking natural gas prices have pushed up electricity prices to levels usually seen in summertime. My story in the Feb. 9 issue of the New York Post has more discussion of this subject. My earlier NYP&L post on this topic is here.
Charges by electricity generating companies change constantly. Con Edison adjusts its customers’ supply charges daily, and the charge quoted on your bill is an average of the daily charges during your billing period. Because different customers have different billing periods, the per-kilowatt-hour supply charge on your bill may differ from what this chart shows. Don’t worry about that — over time, everyone’s charges even out.
Con Edison says it passes on the generating companies’ charges without markup.
This chart doesn’t show delivery charges, which cover Con Edison’s cost of maintaining transformers, cables, and other equipment. That charge is regulated by the state, and hasn’t changed in more than a year. It’s shown separately on your Con Ed bill.
Customers of upstate utilities have it even worse than Con Edison customers this year — check out this Jan. 29 news release from the state Public Service Commission.
