Barely anyone knows about this. It was (likely purposely) buried in a long junk mail notice they sent out to customers.
You can save substantial money on your electric bill, with virtually no downside, by simply switching your type of rate plan.
First off, you need to be a Southern California Edison customer. If you're not, ignore this post.
Start by going to this URL: http://sce.com/bestrate
Enter your account number (you'll find it on your bill), and your ZIP code.
You will then be shown a table of your past 12 months' worth of bills. There will be about 7 different columns. The first column will be your existing rate plan, and the amount your bill was each month. The next columns will be the other plans you can switch to.
Scroll to the bottom and you will see the average savings for each plan, based upon your last 12 months of usage.
For example, I found that one of the plans would have saved me 23% had I been on it. My current plan -- the standard domestic one -- was the worst one.
You then click on the link at the bottom of the table of the column of the plan you want to switch to.
Obviously I switched to the one with the 23% savings.
It will take up to 2 months to take effect, which is kinda bullshit, but I'm glad I found it, especially with summer coming up.
What are these plans?
Southern California Edison is allowing you to switch to "Time of Use" plans, where you pay above normal rates for peak time electricity usage, but below normal off-peak. Since I stay up late at night, that's probably some of the reason I am going to save around 23% by switching to one of their Time of Use plans.
Anyway, there's just about no downside to this, aside from the small potential to screw yourself if you abruptly change usage patterns. But I think that a 12-month sample is pretty good to determine what plan is best for you, and that link I posted helps you pick the best one.
