Application of Risk Analysis to Evaluating M&V Requirement for Energy Efficiency Program
MetadataShow full item record
Since 2005, CIPP of New York Energy Smart has waived the monitoring requirement for lighting projects with small projected savings that are 600,000 kWh/yr or less. There is potential to further increase the threshold savings with additional administrative efficiencies, but also with increased risk that the estimated savings may not be realized. This paper presented a risk analysis of the threshold for small lighting projects by running a Monte Carlo simulation. The preliminary result of this study shows that increasing the size of lighting project savings for which M&V is waived to 1,400,000 kWh per year would introduce an error of only ±5% to the sum of all lighting savings. The error introduced at the program level would be approximately ±2%. The lessons from this experiment may be used to conduct large-scale risk analysis to optimize evaluation cost allocations for more complex energy efficiency program portfolio.
