Cat® Electric Power SpecSizer

SpecSizer is a free, PC software tool that allows users to select the most appropriately sized diesel generator set for virtually any electric power project. Users can size for their power needs with generator sets as small as 14KW or as large as 4000KW, and the SpecSizer tool can parallel up to 25 generator sets. Users input the details of the on-site power required including voltage, load demand, load types, duty application, maximum ambient temperature, altitude, EPA emissions and more. As a result, this software tool allows users to determine a truly customized and comprehensive power solution. SpecSizer is also equipped with features such as the 20-Step Wizard tool that uses program logic to calculate the smallest possible generator set along with the least number of load scenario steps, which provides an optimal rating and footprint that minimizes costs. SpecSizer allows users to make load step changes to any user-defined criteria on the load scenario tab to assess possible sizing results. The SpecSizer software has revolutionized generator set sizing by simplifying the process. Not only does it include filtering processes to align the generator set selection with available options, it also provides web links and tools, such as volts/hertz optimization, percent of intermittent motors, and percent genset capacity used (EkW) to help with analytical and strategic decisions. One of the web links even provides the precise spec sheet you need for your job specification.
