Resource adequacy—ensuring power systems have sufficient resources to meet demand reliably—is a key focus of the Global Power System Transformation (G-PST) Consortium. In 2021, G-PST established the Resource Adequacy Research Team to explore how the rise of variable resources, combined with extreme weather events, will require new planning approaches to maintain reliable, cost-effective power systems.

The team collaborated with the Energy Systems Integration Group (ESIG) to publish a report on redefining resource adequacy definitions, approaches, and techniques. Since then, the team and broader G-PST research groups have led numerous studies, training sessions, and events to advance resource adequacy planning.

One major effort includes G-PST’s collaboration with Grid India, where Pillar 2 provided training on the open-source Probabilistic Resource Adequacy Suite. This enabled Grid India to conduct its first-ever resource adequacy study. After G-PST trained one regional operations team, Grid India expanded the training internally, and these tools are now used for ongoing national assessments.

G-PST has also hosted several events to share global best practices, with a focus on both market-based and non-market approaches to resource adequacy:

  • 2023 Workshops: G-PST organized three workshops featuring insights from European and North American experts. Two virtual sessions established key concepts:
    • Resource Adequacy for Net Zero Grids – Hosted by the Electric Power Research Institute (EPRI), covering resource adequacy methods and metrics.
    • G-PST Technical Workshop on Resource Adequacy and Market Design – Hosted by the National Renewable Energy Laboratory (NREL), exploring market design implications.
    • A follow-up workshop in Washington, D.C., gathered 59 participants, including system operators, researchers, regulators, and policymakers, to discuss modern resource assessment and procurement mechanisms.

A summary document and an under-review journal article synthesize discussions from all three workshops, focusing on resource adequacy methodologies and procurement strategies for addressing load growth, extreme weather, economic trends, and emerging grid resources.
