Abstract: A system and method for detecting and responding to device tampering in an Energy Management (“EM”) device is disclosed. The EM device is provided with mechanisms to detect and indicate unauthorized tampering with the device. Further, in response to detected unauthorized tampering, the device may take actions to protect the integrity of data generated by the device as well as protect any confidential data stored within the device. Such actions may include preventing further device operation, generating warnings to the device owner/user, marking subsequently generated data as suspect, destroying stored confidential data, etc.

Abstract: The disclosed embodiments comprise a Rate Engine and system and method for the use thereof, which may execute on a computer or other processor and which provides cost analysis with a finer granularity than monthly or billed costs. The Rate Engine receives inputs such as utility data and rate data, and generates cost data on a per logging interval basis. A logging interval is the finest sampling frequency available, which varies depending on the application, such as from microseconds to minutes or hours. The resulting cost breakdown allows the user understand and analyze their energy costs in the same manner that they analyze other costs of business such as labor and goods.
