A method including receiving energy usage data representative of energy usage of a customer during a particular time period. The energy usage data is sign with a digital signature of a utility. The method includes receiving input of a customer effective to select a data block of the energy usage data. The method includes redacting the selected data block from the energy usage data in response to the input. The method includes calculating a hash value for the redacted data block using a per-customer key that is unique to the customer, an initialization vector, and a counter. The method includes replacing in the energy usage data the redacted data block with the calculated hash value corresponding to the redacted data block.
