[RE-wrenches] Fwd: Demand Charges and Time of Day Charges

[Michael Welch]

Hi gang. 

I don't really want to get into discussions about rates and charges at individual utilities because there are so many different ones represented by territories you all work in. Probably hundreds.

So if we could keep the discussion to design and equipment strategies in this age of unreasonable charges, that will be helpful for the many.

>The Demand charge I am familiar with is the Duke Energy's demand charge based on the highest 15 minutes recorded in the monthly cycle . I do not know about FP&L 'S I have heard that utilities in Florida are going to start using Demand  Charges like this AND /OR Time of Day on residential customers ! .Also if a customer ( typically one who uses an instaneous electric water heater I.e. 11,000 watts ) blows the transformer THE CUSTOMER pays for the transformer upgrade in all cases by all utilities .  FP&L , Duke , and the large utilies in Florida hate residential and commercial solar AND look ALSO  for any way to gouge their customers . Any advice on how to overcome Demand  Charges and time of day Charges CHEAPLY like the use of timers and or other strategies is important . Sizing adice on batteries and inverters also . Thanks .
