Resource Uncertainty:
The shift toward renewable energy introduces challenges in managing resource adequacy and system stability.
Ensuring a reliable grid amid this transition requires a diverse energy mix, advanced modeling, multiple adequacy metrics, and flexible long-term planning.
The transition from coal to natural gas, renewables, and battery energy storage increases operational risks, requiring updated tools and strategies to ensure reliability in an evolving energy landscape.
Why It Matters
Uncertainty in fuel and generation resources adds complexity to planning and operations. As the energy mix evolves with increased adoption of renewables and growing dependence on natural gas, reliability planning becomes more difficult, particularly as resource uncertainties such as fuel deliverability and load variability become more pronounced.
What SERC Is Doing
SERC identifies and tracks trends in resource adequacy through regional assessments. The organization collaborates with stakeholders to understand changing resource profiles, identify potential gaps and provide insights to help guide long-term planning. By coordinating with NERC and participating in scenario-based studies, SERC helps ensure that evolving energy trends are addressed proactively and with strategic foresight.
What You Can Do
Participate in SERC's resource adequacy assessments and provide input.
Stay informed about changes in fuel mix and generation policy.
Contribute data and insights to working groups focused on long-term planning.
