Calculate Your Savings (If Any) by Switching to ConEd's Time-Of-Use Rate

Submitted by docmarionum1 t3_10h68iz in nyc

tl;dr: Follow the instructions here to see how much you would have paid in the past using the time-of-use rate.

I recently got an email from ConEd promoting their time-of-use rate. This scheme is good for the planet by encouraging load shifting, but is it good for my wallet? I live in an apartment where my only option to use less electricity in the summer is by sweltering.

But maybe the new scheme could save me money even if I couldn't shift my electrical demands to off-peak hours?

I built a tool using Google Colab which uses your actual electricity usage to determine what your electricity delivery costs would have been under their standard rate and the time-of-use rate. I found that I could have saved about $80 last year by switching to time-of-use, even without changing my behavior.

The tool is a little bit technical, but I added instructions on how to get your data and run it in case it's helpful for others.

If you do this, keep those as blank lines. The code explicitly skips the first 5 lines so it'll break if they're not there.

Very interesting tool. Does this mean you'll be switching to time of use rates?

Yeah, that's the plan. I was sort of holding out in case another redditor caught a bug in my code and realized I wouldn't save money, because I was really surprised by the result. Once you switch you're stuck for 12 months.

This is so cool! I have been wondering how to calculate the difference since I got that email this week. But it looks like you broke the coned website haha they can’t handle all this traffic? I’m having trouble downloading my data.

You probably save more money by reducing electric use via more energy efficient devices. Change to led bulbs, insulate your windows to reduce air leaks and use curtains to block light

Thank you! The results are crazy- I could save 1/4 by switching. Guess I should. Really appreciate your effort.

I tried out your tool and while the graph shows 12 months, the delivery costs display under the graph only shows 1/1 through 9/9. Is that a glitch or intentional?

Definitely a glitch. What are the dates of your export?

I stitched it together with two separate exports. One from 1/1 through 6/30 and the other from 7/1 through 12/31.
