Summary
The bulk power system is under pressure from electrification, decarbonization, and rising computational demand, requiring a shift in planning and design. At the same time, transmission system capacity constraints are limiting interconnections for new generation and load assets.
Read more Read lessDeveloping robust and reliable transmission plans will be critical in support efficient and economic expansion of the transmission system. However, traditional transmission planning methods, which rely on static snapshots of historical worst-case conditions, are inadequate for addressing the variability and uncertainty introduced by extreme weather and renewable generation under this changing paradigm of system needs. To respond, planners will need to adopt integrated, long-term approaches that combine economic, reliability, and resilience assessments to capture the following criteria:
•
•
• Weather-driven impacts on generation availability and efficiency.
Temporal and spatial relationships between weather, generation, and load.
High-risk operational periods using resource adequacy and production cost models. This paper aims to summarize and describe a practical methodology that will allow transmission planners to consider variability and uncertainty across multiple dimensions including weather, load, and generation availability.
