Identify one major compliance requirement for Reliability Coordinators.

Reliability Coordinators play a crucial role in ensuring the reliable operation of the bulk electric system, and one major compliance requirement they must adhere to is the implementation of NERC reliability standards. These standards are designed to provide a framework for maintaining the reliability of the electric grid, covering various areas, such as system planning, operations, and communications among different entities. By implementing these standards, Reliability Coordinators help ensure that operators can respond effectively to real-time system conditions, manage emergencies, and coordinate the operations of multiple utilities.

The other options, while related to energy management, do not fall within the primary responsibilities of Reliability Coordinators as defined by NERC. Regular audits of renewable energy contracts and management of residential electricity tariffs pertain more to regulatory and market functions rather than reliability oversight. Likewise, developing public awareness campaigns is important for consumer engagement but is not a direct compliance requirement for maintaining grid reliability. Thus, the emphasis on the implementation of NERC reliability standards highlights the critical role that Reliability Coordinators have in overseeing and ensuring a stable electric grid infrastructure.
