Load Controllers


Simply put, a load controller is like a cruise control for your electric system. You set the level of savings, you reap the benefits.
How does a load controller work?   A load controller constantly measures the usage of power in your home and directs efficiently to a pre-set priority which lowers your demand and thus your bill.  As the demand increases, the load controller "sheds" (shuts off), lower priority appliances to maintain a user pre-set demand level.  Dropping your demand 4kw = a $48 reduction per month.  It's easy to calculate your savings based on these numbers (estimate based on a 1500 square foot, all electric home), larger homes have much larger savings.

This is the Load Commander LS series. The digital read out offers information including: time of day, current demand limit set point, current home power useage and load status indicator lights. This system is easy to interface with, is very reliable and resistant to lightning damage.



  Easy to use!  Saves on APS bills

Set the Load commander once for your summer load and once for
your winter load...it's that easy.  This unit belongs on every home
on the APS power grid in conjunction with the "Combined Advantage
rate.  Why pay 14 cents per KWK on the Time Advantage Rate
when you can be spending 5 cents on the Combined Advantage Rate.

We carry all brands of load controllers but prefer to install the Load Commander LS series. This unit is fully compatible with all local electric rates, has built -in calenders and several timers. These timers tell the LS when off peak rates start, what day it is and the current time. You can set your water heater to run during off peak times using the LS timers as well. The internal timers and micro-processor are backed up with a lifetime lithium battery to retain program memory during power outages.

Dorothy Marzella in Scottsdale has a four bedroom ranch with a pool and has saved $16,000 in twelve years on her APS bill! Although this figure is on the high end of most of our customers, you can expect at least a 25% drop in your monthly bill with little or no change in lifestyle, many save as much as 40%. 

JW Flint:
"I purchased a home in Scottsdale over three years ago;  3500 Sq ft with two 5-ton A/C units, two water heaters, pool, etc.  A beautiful home with an enormous electric bill.  We are on the APS best rate plan .  We were paying 330/month on the average plan (even with programmable thermostats) with the actual peak summer bill exceeding $400. 

Two years ago you installed the Commander LS load controller.  On the averaging plan our monthly bill is now $154 and our highest single monthly bill has been $225 over the the past two years.  A savings of $4200 in just two years.  The Commander has been well worth the investment.  I just wanted to thank you and let everyone know the savings are real."
