Energy savings claims

[gzobel]

We recently encountered another company claiming that power factor correction capacitors can save up 20% of kWH if applied at the load. They also used our white paper on at-the-load application without our permission. IEEE states that a given plant will see from 2% to 5% savings if applied properly at-the-load. Beware the snake oil salesman.

I hope your white paper makes it clear that it is KVA-HR (i.e., joules), and not KW-HR, that can be saved through the use of capacitors. But thanks for the warning. Welcome to the forum.

Years ago one of the local "high pressure" fixture salesmen formed a separate corporation and began selling something called a "SAVAWATT". It was designed to save energy in flouescent fixtures -- and was applied to the ballast--the little black box gizmo. A few large office building went thru and installed them on every fixture(two to a fixture). Well eventually they realized very little energy was saved-if any?? Then after about 14 months these things started to fail to the point that they had to remove them. Where was the Salesman??? His company was out of business !!

Can you post your white paper?

If you are a commercial building with some big motors and are charged by peak power, then this could have some merit. But for the average joe or harry it's not for you.
or.. no.. nm...
