Methods and systems for managing, tracking, and displaying power usage information in connection with colocation datacenters are described. In particular, one or more current transformers determine an amount of current associated with breaker positions of a breaker panel. The current readings may then be used to construct one or more virtual circuits. Access to the current and power readings associated with the virtual circuit is provided to clients via a communication network. Additionally, the current readings may be utilized to track actual current and/or power use in conjunction with one or more client allocated amounts of power.
