This success story describes a collaboration between Salt River Project (SRP) and EPRI to address limitations in traditional resource adequacy studies caused by insufficient temporal resolution in future climate data. Utilities increasingly face planning and operational uncertainty due to evolving weather patterns, electrification, and changing resource mixes, yet future climate datasets have historically lacked the hourly granularity and consistency required for robust reliability assessments. To bridge this gap, EPRI developed a forward-looking hourly weather dataset tailored to SRP’s planning needs, incorporating variables such as temperature, humidity, wind speed, and solar irradiance for future climate scenarios. The approach applies a climate data translation methodology that preserves historical variability while aligning projections with utility-ready formats. The resulting workflow enables integration of hourly climate-informed inputs into existing planning models and establishes a replicable approach for utilities seeking to enhance long-term resource planning and reliability analysis under changing climate conditions.
