OptiMiser provides a first in its class automation system that matches utility bills with weather data.
- System identifies sufficiently complete data for the period of user-entered utility bills.
- Iteratively selects stations until the 10 closest matching stations are found with adequate data. Selection of weather stations is based on regression analysis developed by NREL that results in a weather similarity heuristic weighting differences in latitude, longitude, altitude, HDD, and CDD to identify similar stations.
- Utility bill analysis is designed to make maximum use of 1 to 12 utility bills from multiple fuels.
Analysis is able to handle gaps in data and irregular billing periods, properly incorporating each bill datum in the analysis.
