An Economical Energy-Efficiency Solution

Mistaken Identity – just the facts…

It is common to confuse the VCG with other energy saving devices. Fact is no other technology like the VCG is on the market today. True, the VCG is a unique, patented technology that uses fundamental electromagnetic principals to reduce energy consumption economically.

VCG = an “Economical Energy-Efficiency” solution

Commonly confused and grouped with the VCG are “hot side” devices, which are capacitor devices. Capacitor based “hot side” devices store large electrical surges and deliver them during load-use to save energy. Their primary application has been in manufacturing with large inductive loads. This technology has been available for many years though most applications still require tuning maintenance.

VCG is not a “hot side” capacitor device and requires no maintenance

The Problem – how long has this been going on….Technological advances over the past thirty years have changed the consumer load profile from inductive to predominately rectified capacitive loads today; more equipment and appliances are electronic and more consumers use them. Energy efficiency has garnered new attention due to the rising costs and expanding carbon footprint (CO2 emissions). The world is competing for resources and lighting up. The new load profile exacerbates non-efficient use of electricity. Electrical current out of phase and polarity, referred to as “noise” or “harmonic distortion” is an undesirable by-product of the electrical grid and new load profile. Today’s electronic and electrical equipment by design seek power in proper phase and polarity and draw on the electrical system continuously to meet this function. The VCG addresses this issue like no other products do.

Distribution

• All current returns to the source through the neutral• The neutral completes the load’s electrical circuit• The neutral is grounded to panel (equipment) ground• The current stays on the neutral because of the ground’s resistance

Loads and the VCG Impact

All electrical systems are a combination of: Capacitive – including AC to DC rectifiers

• Fluorescent Lighting Ballasts• Laptop & Desktop computer power supplies (switching)• VFD drives• Video Game Consoles• Screw in fluorescent lamps

Resistive• Incandescent lamps, toasters, space heaters, etc

Inductive• Motors, compressors, fans, pumps

VCG is an Inductor• Inductors change current into an electromagnetic field• Field strength increases as current increases• This field attracts certain frequency waveforms

VCG attracts the harmonic distorted waveforms• These waveforms include 3rd, 5th, 7th, 9th, 11th harmonics• These waveforms are capacitive in nature• It does not attract energy at the fundamental (60Hz)• Waveforms outside the fundamental are commonly referred to as electrical “noise”

VCG Function

VCG Function

Electrical “noise” in the CURRENT waveform appears on the neutral line

• The neutral is the addition of the panel’s phase currents• There is a common-mode noise waveform as well• Both waveforms are measured by the digital power company meter with Rogowski coil• KWH charges will appear on the monthly bill

What others are saying – EPRI & GE

EPRI -2004“Electricity savings and Computer Power supplies”

GE - Capacitance in electrical systems• “Each element of an electric system is related to every other element by capacitance, just as each element contains resistance and inductance. These unavoidable distributed capacitances are usually small but important. It is difficult to make accurate calculations of distributed capacitance, but there are some useful approximations available. “Capacitance, GE Industrial Power Systems Data Book, 12-3-62”

A s a company, we were looking for ways to reduce our energy consumption in a cost effective manner. We turned to the Voltage Control Guard and decided to do a test pilot in our Atlanta facility. We knew that because of our environment and variable production demands, we had to normalize the data we collected in order to identify savings.

The raw data we collected over the 6 month period indicated we had significant savings. Since there are numerous factors that affect the consumption of electricity, especially in a fluctuating demand environment like ours, we used total kWh/ unit as the metric most indicative of our business. From Dee 2009 to May 2010, KWh/unit decreased an average of 13% over the 6 month timeframe from the same period a year prior and 28% from the same period two years ago. After thinking more about the metric we used for the comparison, we were not comfortable that total kWh/unit was the best metric to use. We felt that there were too many variables that entered into the 6 month test to consider it valid.

We then suggested we do a shortened test and use a different metric which would be more representative of kWh consumption. Since we deal in pounds, kWh/lb and kWh/RH were the best metrics. The test was done over a 5 day period which coincided with our production week. We ran the test like this so we could normalize conditions as much as possible. The shorter duration test data indicated that the kWh/RH decreased by 8 .0 2 % by installing the devices.

We realize that this savings was achieved over a short period and that greater savings may be possible over time. Even with a savings of 8.02%, our return on investment is less than twelve months.

We were very impressed with the results we achieved and would strongly recommend the Voltage Control Guard as an affordable and effective way to reduce energy consumption.

February 2, 2010 Mr. John Harkonen Clean Power Technologies, LLC P.O.Box 2547 Lilburn, GA 30084 Dear Mr. Harkonen,

In December of last year, through the services of a licensed electrician, I installed 2 Voltage Control Guard (VCG1) units at my food establishment located at 6434 Lawrenceville Hwy, Tucker, GA 30084.

My monthly electric bill was from 12/28- 1/27. The number of days in our billing cycle (30) this period was two days less than the same period a year ago. We did see a drop in average kWh/day by 14.98% as evident by our electric bill.

Another factor we had to deal with this year unlike any of the two prior Januarys is weather. It was much colder this year than the prior two years at this time. We are very pleased that your energy management device (VCG1) has helped reduce our kWh/day consumption.

As a Five Guys franchisee, I highly endorse the VCG1 as an energy savings product that will save our operation thousands of dollars. I have installed additional units at my other Five Guys location.

Best regards,

Andy Hahn, Owner Five Guys 6434 Lawrenceville Hwy Tucker, GA 30084

Attached is the updated spreadsheet with the October consumption comparison. Even though we only had 2 years of history, we are still seeing +15% savings per month on an average. For me, this is solid validation of the product and we can move forward with a plan for campus integration. The only hurdle now is funding. I recall our conversation on Save Energy providing the “up front” funding, but we will not be able to do this with our purchasing regulations. I have not had an audience with Residence Life with my proposal to them. Aside from the residence halls, we need an evaluation for an academic building with a generous utility history for comparison. Since we are still “fuzzy” on where the GiG2 devices should be installed, I would like to request an evaluation from a knowledgeable person to develop a project scope. We will then allocate funds (partial or in whole) to address the academic building for evaluation. If the academic building produces favorable results, we’ll include campus wide implementation with our other energy conservation measures.David Handwork, P.E.Facilities ManagementArkansas State University870.680.4691
