UPS Efficiency Calculator
This calculator allows you to compare the efficiencies of an Eaton UPS featuring Energy Saver System with traditional UPS models. It takes energy charges into account based on the location of the UPS in the United States as well as data center infrastructure efficiency and utility demand charges. The final calculation details energy and cost savings, including energy usage, electrical savings and greenhouse gas savings.

Commercial Building Energy Usage Calculator
The US DOE commissioned an energy consumption study of over 4.6 million buildings and segmented the data by type of enterprise and by size of structure. The study did not include manufacturing locations. To use, simply identify your type of enterprise (education, healthcare, etc.) and the facility size. If you know your monthly energy bill, the calculator will compare your energy bill to the US average for a similar building.

Enclosure Cooling Calculator
The amount of cooling is dependant on the dimensions of the enclosure, the paint color, the amount of insulation and latitude of the installation. Use this calculator to determine the amount of cooling needed. This calculator can also be used to determine the amount of auxiliary heating necessary to maintain a non-condensing internal environment by raising the internal temperature above the external ambient.

Power Factor Calculator
Texas Utilities (TXU) has begun a new program to penalize customers for low power factor. Use this calculator to determine if installing capacitors would be beneficial based on data available from your TXU energy bill.

Predictive Diagnostics Calculator
Advanced Partial Discharge technology now allows you to predict imminent insulation failure within medium voltage equipment, saving the expense of equipment loss and downtime due to catastrophic, unexpected failure. Use this calculator to determine if this technology makes sense for your application.

Also includes a generic ROI calculator usable with any hardware or financial decision. If you know the initial cost, annual savings and projected life of equipment, this calculator will determine the compounded rate of return, also know as IRR.

Battery Life Extension Calculator
Periodic testing or other switching (as might occur preceding a storm) causes transitory events that are detected by downstream UPS and other battery backed system causing a short duration discharge during the switching event. This calculator determines the amount of degradation caused by this switching and computes an ROI to install a soft-load device that eliminates these transitory events.

Spot Network 'Quick Check' Calculator
Applying a spot network instead of a secondary selective (main-tie-main) distribution system decreases the likelihood of a power outage by 80%, but costs the same as the main-tie-main system. The catch is that not all applications are candidates for spot network systems. While a detailed engineering study is needed to know for sure, use this calculator to eliminate some applications.

Spot Network 'Complete Check' Calculator
After you have used the "Quick Check" calculator as a first-pass analysis, use the "Complete Check" calculator to provide a more in depth evaluation on whether your diverse sources are candidates for a spot network. To provide a more accurate analysis, the Complete Check calculator requires more detailed information than what will be listed on your energy bill. In most cases obtaining this additional information will require that you contact your electric utility.

Peak Shaving Calculator
Operating a local generator can make sense as long as local environmental permits are updated and you have a firm understanding of the economics of operating the generator. To help know if running a local generator makes sense, use this calculator. It uses commonly available data from your energy bill to estimate the right size of a standby generator and provide IRR (rate of return) costing data.

Life Extension ROI Calculator
When providing aftermarket "Life Extension Solutions" many times you are called on to provide the financial benefits of the solution. The complex time value of money computations are done with this calculator. It works on a costs comparison of the solution that is offered and the cost of doing nothing. The cost of doing nothing is taken from the IEEE Standard 493, or the so-called “Gold Book” and represents the number of hours of downtime you would expect over the useful life for that equipment. The expected duration of an outage is combined with the customer’s cost of each outage, and we have total downtime costs. The calculator then assumes this downtime cost would be eliminated with the implementation of the offered solution. Eliminating this downtime cost is evaluated as a payment to the customer and, taking this as a future cash flow, the calculator compares this cash flow with the present value cost of the solution.

Generator Regulator Replacement Evaluator
This calculator will perform a financial analysis on the merits of replacing existing rotary excitation equipment with new digital static excitation equipment. The evaluation method used to evaluate these merits is:

1. Compare the cost of doing nothing with the cost of replacing the static exciter.
2. The cost of doing nothing is based on the likelihood of failure (from IEEE 493-1997 Gold Book), multiplied by a user entered cost of downtime.
3. The cost of replacement can be entered if known or it can be estimated based on exciter size and characteristics of site.
4. The new replacement exciter reduces the likelihood of failure of the excitation system to nearly zero, eliminating downtime costs due to excitation failure.
5. These cost savings are accumulated over the life of the equipment, discounted to present dollars and compared to the installation cost.
6. An interest rate is calculated that would produce the cash savings based on the initial investment cost and this value is returned as an Internal Rate of Return (IRR).

This evaluation is conservative as it does not include the benefit due to equipment depreciation, nor does it include the benefit of improved generator operation. As a result your final IRR will be higher than the value calculated here.
