Regulatory Update   |   Jun 13th, 2017 NERC Identifies New Reliability Risk due to Utility Scale Solar Generation Inverter Design


NERC has released a report documenting its findings and recommendations related to reliability risks from utility scale solar generation projects. It has implications for PRC-024 compliance and generation, interconnection and protection system technologies.

TRC’s latest Regulatory Update on this topic reviews:

  • Background of the Blue Cut wildfire tripping event
  • Key findings from NERC’s analysis of the event and the operating characteristics of impacted equipment
  • Impacts and potential revisions to Standard PRC-024
  • Role of the newly created NERC Solar Resource Performance Task Force
  • Next steps for ensuring reliability and NERC compliance

The newly identified operating characteristic of utility scale PV installations will require proper planning, re-design, and coordination going forward to prevent risk and remain in compliance. 

NERC plans to produce lessons learned and technical reference guidance from the information gathered through analysis of this event.
