Powertech Labs, a global leader in grid compliance solutions, can assist generation owners in meeting the North American Electric Reliability Corporation (NERC) Generator Protection and Control (PRC) standards PRC-019/24. 

Powertech engineers specialize in grid compliance testing, studies, and reporting. We understand the need of generator owners to maximize production while maintaining compliance. Powertech is committed to helping our clients meet interconnection standards, including NERC PRC-019/24, which are among those standards that are constantly monitored and enforced.


PRC-019-2: Coordination of Generator or Plant Capabilities, Voltage Controls, and Protection

This standard ensures the generator protection system is well coordinated with excitation controller settings, equipment capability, and other limiting devices. Powertech engineers review the protection settings, Automatic Voltage Regulator (AVR) settings based on the unit and plant operating conditions, recommend setting changes if necessary, and prepare all reporting documents to meet the compliance requirement.

PRC-024-2: Generator Frequency and Voltage Protective Relay Settings

This standard verifies that the generator and other related protective relays do not trip the unit for defined frequency and voltage excursions. Powertech engineers evaluate the protection settings and prepare all the reporting documents to meet the compliance requirement.

Who Must Comply

NERC PRC-019/24 standards apply to:

  • Individual generator / synchronous condensers rated at 20 MVA or greater
  • Cluster of generating units with total generating capacity of 75 MVA or greater 
  • Any generator with black-start capability

Recent revisions also extended applicable facilities to dispersed generating facilities such as wind and solar farms.
