Feasibility Studies
The GC CEAC has performed over 30 CHP feasibility studies in the last two years for facilities in a variety of market segments. Sample feasibility studies can be downloaded by clicking on pertinent links on the left. We use a two-step process outlined below to perform CHP feasibility studies. Feasibility studies assess the technical and economic viability for projects. To determine project feasibility, we conduct a two-step evaluation comprised of an initial screening analysis followed by a detailed analysis if warranted.
Level 1 Screening Analysis:
- Establish if a site is a potential candidate for a clean energy project
- Uses industry averages and "rules of thumb"
- Considers a facility's monthly electric and gas consumption data
- Results include simple payback
- +/-30% accuracy in savings in costs
Level 2 Detailed Analysis:
- Determine if a site is a viable candidate for a clean energy project
- Hour-by-hour simulation of building energy use using DOE software
- Calibration of baseline model to actual utility bills
- Sensitivity analysis for variability in electric and gas prices
- Well-defined CHP configuration and equipment set
- Evaluation of multiple scenarios
- Pro forma financial models generate internal rate of return (IRR)
- Calculation of emissions reduction potential
- +/- 20% accuracy in savings and costs
