CHP system Analysis
A review of CHP analysis software found many useful tools. One of these tools, the Cogen Ready Reckoner, is now available as a free download.
The BCHP Screening Tool, originally developed by GARD Analytic,
is software that can be used to estimate the energy consumption
and economics of CHP systems in commercial buildings. This
tool uses the DOE-2 simulation engine and includes data
libraries that describe generation equipment, HVAC equipment,
utility rates, weather, and many building types. This tool
is available upon request from Mike
Macdonald.
A complementary software tool that determines the optimal installed capacities for prime mover and absorption chiller in CHP applications is also available at no charge. The CHP Capacity Optimizer uses hourly load data, generated by building simulation tools such as the BCHP Screening Tool, along with electricity and fuel pricing data as inputs to a nested optimization/simulation model. The Excel-based model determines the optimal CHP capacities that maximize the net present value of the life-cycle cost savings due to employment of CHP systems.

DE Program Planning Support Analysis
This work provides the foundation for informed program management decisions, including definition of program priorities, direction, effectiveness, and strategy. It also facilitates deployment of advanced technologies by conveying the full extent of potential benefits and role of DE in the energy market. This analysis also supports cooperation and partnership with other offices and other government agencies, such as the EPA, FERC, and the IRS.
The scope of the analyses range from national to regional to the single feeder level. The analysis tools have included the Oak Ridge Competitive Electricity Dispatch Model and the Building Energy Analyzer. The most recent efforts include an evaluation of DG’s displacement of central generation sources, an examination of two feeders in the Southern California Edison system, and a review of niche opportunities.
