White paper discusses how new load growth could lower rates by spreading fixed costs and when it may require new investments that could increase rates As utilities face an unprecedented wave of large load requests driven by data centers, electric vehicle fleets, and advanced manufacturing, a critical question has emerged: how will these new loads…

ESIG Large Loads Task Force finds that treating demand flexibility as a planned capacity resource—rather than an ad hoc, short-term measure—can accelerate large load interconnection while protecting grid reliability. The Energy Systems Integration Group (ESIG) today released a new report examining how utilities, regional grid operators, and large load customers can address growing resource adequacy…

The Energy Systems Integration Group (ESIG) has released a new white paper, “Historical and Modern Large Loads: Characteristics, Context, and Industry Actions to Meet Grid and Customer Needs,” outlining the key differences between traditional large loads and new large loads, such as data centers, and discussing the main implications for system planning and operations. The…

ESIG Large Loads Task Force report shows how careful tracking of large load disturbance events can inform the interconnection practices needed to maintain reliable and secure grid operations. The Energy Systems Integration Group (ESIG) has released Large Load Disturbance Events, a new technical report documenting recent grid disturbance events in which large, power electronics–based loads…

The Energy Systems Integration Group (ESIG) has released the EV Load Forecasting Guide, which articulates core principles for EV load forecasting, synthesizes leading practices, and assists utilities, regulators, and stakeholders in adopting effective forecasting approaches for electrified transportation. Utilities’ forecasting efforts underpin billions of dollars in grid investments that ensure system reliability. While, historically, forecasting…

As data centers and other large electronic loads reshape demand on the power system, the models used for grid stability studies weren’t built for these technologies. A new ESIG report addresses that gap. The Energy Systems Integration Group (ESIG) has released a new report, Large Load Modeling for Dynamic Studies: Current Practices and Recommendations, developed…

Stress testing simulates grid performance across a range of weather-related high-risk conditions and guide planners in determining which grid improvements, including interregional transmission, can most cost-effectively support grid reliability during high-impact, low-probability events. The Energy Systems Integration Group (ESIG) has released a new report, Stress Testing Methods for Evaluating Resilience to Extreme Events: Valuing Interregional…

Report provides guidance for system operators and utilities as they develop interconnection performance requirements for large electronic loads tailored to their own jurisdictions. The Energy Systems Integration Group (ESIG) has released a new report, Large Load Performance Requirements: Current Practices and Recommendations, as part of its Large Loads Task Force. The report provides minimum interconnection…

Load forecasters face significant uncertainty as emerging large loads are poised to drive power demand—this report offers recommendations for load forecasts for more efficient power systems planning. The Energy Systems Integration Group (ESIG) has released a new report, Forecasting for Large Loads: Current Practices and Recommendations, reviewing utilities’ and system operators’ approaches to forecasting large…

New ESIG report presents an “integrate, broaden, deepen” approach that connects siloed transmission planning tracks that run in parallel, and supports the coordinated development and selection of transmission upgrades to deliver multi-driver, multi-value transmission portfolios aligned with FERC Order 1920. The Energy Systems Integration Group (ESIG) today released Modernizing Transmission Planning: Integrating Silos to Deliver…
