Larry,  I'm curious what loads you would shed during high demand?  I use a
digital optic sensor on my meter to measure power consumption but don't
have any loads I would want switched off automatically.  I am also curious
what sensors you are using and where you got them from?  I have the same
type of service you have.  I am billed a flat rate per kwh of power
cheaper for the first x kwh per month. How are you billed?

Thanks  Dan Dubay
