They are called Smart Meters.
We just had one installed (Not by our choice).
They send readings via wireless to a nod that records usage during different times.
The meter will allow the hydro company to charge different rates for different times. For us with lights, setting the timers to the lower rate hours will be beneficial in the long run on our bills.

THERE IS NO PERSON REVIEWING YOUR HYDRO BILL AND COMPARING IT MONTH OVER MONTH TO YOURS OR ANYONE ELSES!!

THERE IS NO COMPUTER PROGRAM LOOKING FOR SMALL TIME GROWERS.

The company bills for KWhours and loves it when you use more.
If running 10 x 1000w I might be a little paranoid but even up to 3 x 1000w is not much different than a freezer, tv runing, dryer running while vaccumming, planying the radio and having the lights on in 5 rooms.
What I'm saying is they can't distinguish between lights and normal usage.
