Planetary distress is an ongoing reality
Energy efficiency is a sensible commitment worth making
Decreases our carbon footprint emissions by doing our part to go GREEN
Help meet planetary requirements and promote financial savings
Venergy Group addresses reducing consumption not just sustainability
EPACT 2005 and the EISA 2007 protocols and mandates from the Federal Government requires all States, Territories and D.C. to comply by 2012

Title III, is the Energy Policy and Conservation portion of the American Recovery and Reinvestment Act of 2009 (ARRA). DOE was given nearly $40 Billion to be applied to some of the Energy Efficiency needs of all States, Territories and the District of Columbia (States)
DOE is responsible for overseeing and managing the allocation of all ARRA funds distributed to the States, through the various State Energy Programs (SEP)
Purpose:Stimulating jobs Saving energy Increasing energy generation from renewable sources Reducing greenhouse gas emissions

Delaware was the "First State" to enact most of the DOE stimulus mandates. Key Legislation in the form of new Energy Efficiency Building Codes for all Residential and Commercial facilities was signed into State Law late July, 2009 and these new building code requirements will take effect Jan 1, 2010.
Each State energy conservation plan with respect to which assistance is made available under this Part, on or after the date of enactment of the Energy Policy Act of 2005, shall contain a goalconsisting of an improvement of 25% or more in the efficiency of use of energy in the State concerned in calendar year 2012 as compared to calendar year 1990 and may contain interim goals.”
5
All States must enact new legislation to include the following activities and details on compliance prior to being authorized to dispense Stimulus funding . . . . . . .
Incorporate energy efficiency criteria into procurement procedures
Implement mandatory thermal efficiency standards (new and renovations)
Establish building codes that require adherence to mandates
Commercial code requirements: meet or exceed the ANSI/ ASHRAE/ IESNA Standard 90.1–2007

The adequacy of North America’s electrical grid will decline unless changes are made soon … The demand for electricity is expected to increase over the next 10 years by 19 % in the U.S., but confirmed power capacity will increase by only 6 %
- NERC (North American Electric Reliability Council) -
“Over $16 billion dollars of electricity is unusable energy, but billable in the US.”
- U.S. Dept. of Energy -
7
Up to 25% of billable electricity is unusable
Electric AC motors use more then half of all electricity
Electricity Costs: 1960’s .019/kwh 1970’s energy crisis .044/kwh 2009 .10+ /kwh
Most AC induction motors operate at 80% efficiency under a full load … the efficiency drops dramatically at lower loads
DOE research proves that substantial savings can be found on the running costs of AC induction motors

Power Loss = I² R Loss Extra reactive power that must
be generated is “wasted” due to heat losses in conductors

Enhance the capacity of existing electrical systems
Supply power to more customers without the generation or acquisition of additional power
Reduces capital expenditures by leveraging the existing infrastructure
Keeps utility costs down
Less fossil fuel being used to generate power
Less dependency on foreign oil
12
Inductive loads consume 80% or more of power in Commercial Buildings & Industrial Complexes
Reactive power provides magnetizing current for inductive loads such as:
- Transformers & computers - Motors
- Compressors & HVAC equipment - Lighting ballasts - Elevators & escalators
- Process machinery
Lightly loaded motors are wasteful and exhibit low power factor
The larger loads with longer run times equals more savings to you
13
Power Factor is the ratio between real power (Working) (kW) and Apparent Power (kVA)
Most loads in electrical distribution systems are inductive
Inductive loads require two kinds of current: - Working Power – performs actual work of creating heat, light, motion, etc.
- Reactive Power kVAR – sustains the electromagnetic field
PF measures how effectively & efficiently electrical power is being used

Power Factor = Cos (changed)
15
Too much foam is wasteful because it doesn’t quench your thirst
The foam is represented by kVAR (kilo volt ampere reactance)
The total contents of your mug is kVA
kVA the total of kW (the liquid) and kVAR (the foam)
As your kVAR (foam) approaches zero your Power Factor approaches 100% & the amperage & wattage is reduced
Power Factor should always be corrected at the motor in a slightly
lag position
kVAR (foam) is converted by
the capacitors
16
Capacitors re-align the reactive power to help create the electromagnetic field (EMF) around the inductive windings of a motor
As motors operate, reactive power is “pulled” and “pushed” to and from the capacitor by the motor at 60 cycles per second
Capacitors store & release what motors need to function more efficiently
Capacitors fine tune the motors & eliminate the I² R Loss
Electricity reclaimed and recycled by the capacitors would normally be pushed back through the power distribution lines
Significantly reduce load on transformers to allow facility expansion
Capacitors align, store, recycle and supplies power to inductive loads (Does not work on resistive loads)
How Do Capacitors Work?How Do Capacitors Work?
17
Capacitors improve the efficiency of the electrical systems, increases amperage capacity and reduces the kWH
Maintains quality voltage levels in your system with less voltage drop especially long runs of cable
Helps reduce the harmful effects from the heating of wireing
Reduces the heat and premature failure of motors and other inductive equipment
Motors run cooler & more efficient
Increases life expectancy
Increase starting torque
Decreases demand charges
Reduces maintenance costs

Continuing BenefitsContinuing Benefits
Maximized design savings
Reduces amperage & kWh to the “cash register” (meter)
Saves the customer money on losses
19
Reducing amperage & kW usage directly reflects in dollar savings
All electrical components are purposely oversized by at least 125% - NEC (National Electrical Code)
Eliminate the primary power factor surcharge penalty
Utilities usually charge customers an additional fee (up to 25% more) when their power factor is less than 0.95
Avoid this additional fee by determining the capacitance needed to correct each motor to a higher PF by properly sizing and installing capacitors

Panel mount – accumulation of smaller inductive loads
Equipment mount – larger individual inductive loads
There are Good, Better, and Best locations for installation of units
Adding PF correction capacitors to a lagging PF load improves the Power Factor on the ENTIRE system

Causes
Adjustable Speed Drives Variable Frequency Drives – VFD’s SCR Drives AC Motor Drives (ac/dc/ac) Nonlinear loads (electronic loads)
UPS’s, computers, copiers & rectifiers Many inductive loads have some
amount of harmonic content
Are steady or variable voltage & currents at higher frequencies than 60 Hz (or 50 Hz)
23
High harmonic levels can shorten the life of equipment by 75 percent or more and raise your bill
High levels of harmonic distortion can create stress & problems for the utility’s distribution system, the plant’s distribution system and the equipment that is connected
The result may be the plant engineer’s worst fear — the shutting down of important plant equipment ranging from a single machine to an entire line or process
Consequences of High Consequences of High Harmonic Distortion Harmonic Distortion LevelsLevels
24
The customer is responsible for not causing excessive harmonics
The utility is not supposed to feed you harmonic rich power which alters your meter readings
Some electric utilities are presently charging financial penalties and/or causing service interruptions for customers injecting excessive harmonics into the utility system
A harmonic distortion-based penalty structure, in the manner of IEEE 519-1992, is forthcoming in addition to poor Power Factor
