About this measure
Regulators should require transmission and distribution planners to conduct robust scenario analysis as part of grid development planning. This involves evaluating multiple future pathways for renewable deployment, electrification, and demand growth rather than relying on a single forecast. Scenarios should also capture uncertainties related to policy targets, technology costs, and flexibility resources such as storage and demand response. Regulators can establish minimum requirements for scenario design, modelling assumptions, and transparency of results to ensure consistency and comparability across planning processes. Robust scenario analysis improves the resilience of grid development by identifying infrastructure needs that remain valuable across a range of possible system developments.
