Abstract: The disclosed technology relates to log file processing techniques for providing thermostat configuration guidance. A system may be configured to receive, from a load forecast engine, a plurality of load forecasts associated with a thermostat set point schedule and receive, from a user device, a change in the thermostat set point schedule. The system generates a hybrid load forecast by selecting a portion of a first load forecast in the plurality of load forecasts and a portion of a second load forecast in the plurality of the load forecasts based on the change in the change in the thermostat set point schedule. The system calculates a cost for the change in the thermostat set point schedule based on the hybrid load forecast and a fee schedule and provides the user device with the cost for the change in the thermostat set point schedule.
