I EXECUTIVE SUMMARY Evolved Energy Research (EER) was contracted by Southwest Power Pool (SPP) in September 2023 to produce hourly electricity load shapes for the SPP territory that reflect three electrification technology adoption Scenarios: low (Baseline), modest (Moderate Electrification), and aggressive (Full Electrification). Understanding the potential evolution of these load shapes is crucial for understanding when and how energy is being used and can help in generation capacity and transmission planning, efforts to manage grid stability, and optimizing the integration of renewable energy sources. Rapid increases from electric technologies that are only minimally represented in current electricity loads will create unique challenges and opportunities for grid operators like SPP. For instance, demand by passenger electric vehicles (EVs) may set new peaks, especially during evening charging, requiring upgrades to grid infrastructure. However, smart charging and vehicle-to-grid (V2G) technologies can provide flexibility by shifting demand and supporting grid stability. Commercial trucks transitioning to battery (direct electrification) and hydrogen fuel cells (electrification of fuel production) will represent new electricity demands entirely, with additional spatial and temporal planning implications beyond historical commercial customers. Proper siting of these loads with regards to both travel patterns and grid topology, and their potential employment as SPP FUTURE LOAD SCENARIOS | EVOLVED ENERGY RESEARCH | 3
