2025 Grid Reliability: Progress with New Risks on the Horizon

According to the NERC 2025 State of Reliability (SOR) report, the North American Bulk Power System (BPS) remained resilient and increasingly reliable throughout 2024. Severe weather events—including hurricanes and winter storms—resulted in no operator-initiated load shed, reflecting improved grid weatherization and system response capabilities.

Key Observations

  • Generator outage rates declined, and natural gas production losses reduced.
  • Battery Energy Storage Systems (BESS) played a critical role in frequency regulation, especially in Texas.
  • Grid stability is challenged by high-load data centers; one instance in 2024 saw a 1,500 MW disconnection.
  • Since 2016, inverter-based resources (IBRs) have seen nearly 15 GW in output reductions during 10+ major events due to modeling deficiencies.

Keentel continues to support utilities and developers with IBR modeling and BESS integration to reduce outage risks and support NERC PRC compliance.

NERC’s IBR Registration Initiative: A Wake-Up Call for Non-BES Operators

The new IBR Registration Initiative 101 introduces mandatory registration for GOs and GOPs of inverter-based resources with ≥20 MVA aggregate capacity connected at ≥60 kV.

Required Standards Include

  • BAL-001-TRE-2
  • PRC-012-2, PRC-017-1
  • MOD-032-1
  • TOP-003-6.1, IRO-010-5
  • VAR-001-5, VAR-002-4.1

A FERC directive requires full compliance by 2026, and Keentel is ready to assist with CMEP navigation, standards interpretation, and modeling compliance.

Reliability Insights: Why Energy Adequacy Needs a Rethink

The June 2025 Reliability Insights bulletin highlights that traditional capacity-based planning is no longer sufficient.

Why This Matters

  • Winter storms (e.g., Enzo, 2025) and dunkelflaute events reveal that fuel security, not just capacity, defines grid adequacy.
  • Future planning must adopt probabilistic risk models, energy-centric adequacy metrics, and account for fuel assurance, ramping ability, and seasonal volatility.
  • A 20 GW resource gap is projected for Winter 2029 in PJM unless planning frameworks adapt.

Keentel offers advanced system studies using scenario-based modeling and probabilistic tools to ensure your projects remain grid-adequate and NERC-compliant.
