BioPET Figure I-2: BioPET Main Screen BioPET is a spreadsheet tool designed to assist in comparing diverse bio-power projects by calculating a common economic metric (a levelized annual cost in ¢/kWh) for all projects. BioPET is designed merely as a screening tool and should not be a replacement for an in-depth engineering and econometric analysis. It is meant to be used as a means for narrowing one’s focus from perhaps dozen of ideas to just a handful. gopher Figure I-3: gopher Screen Shot Identifying Effective <strong>Biomass</strong> Strategies: Page 5 Quantifying Minnesota’s Resources and Evaluating Future Opportunities
The birth of gopher came through the acknowledgement that, given the wide variety biomass feedstocks, generation technologies, and infrastructure requirements, the project team would not be able to accurately predict or provide maps for all of the possible combination of resources to assist in specific project development. It was clear that simply providing a series of fixed maps would be too limiting and ultimately not very helpful. A flexible tool that would allow anyone to create their own map focusing only on the resources in which they are interested was deemed to provide the maximum amount of value to project developers. As with BioPET, gopher is designed as a screening tool and its accuracy is only as good as the resolution of the data collected at some time in the past. Before embarking on a specific project, “on the ground” analysis should be conducted to verify accuracy and adjust for recent developments.
