Our bill has gone up a bit compared to previous years but nothing like what you are describing. We just had our largest winter bill ever at $175 for the period from mid-Dec to mid-january. Our most current bill (mid-Jan to mid-Feb) just posted and it was $140. Our usual Winter bills are normally around $100, but we have spent a lot more time at home these two months compared to last year (which is reflected in the increased usage) and our new place is ALL electric, whereas our previous one had gas stove/oven. Overall, I calculated we have seen a 10% increase in cost when all is factored in, which is more or less in line with the PSE&G rate increase.
