How modernized energy forecasting can make grid operations more efficient
Jeremiah Karpowicz | Source: Renewable Energy World | Posted 09/04/2025

Utilities, states, and ISOs are aware of the challenges with long-term load and distributed energy resource (DER) forecasting, but the traditional focus on total annual energy and peak demand for this type of planning made those difficulties manageable. However, factors like the integration of renewables, extreme weather events, and the expansion of customer-sited energy resources have meant that a traditional focus is no longer enough.
AI generated summary
Modernized energy forecasting is crucial for improving grid operations as traditional methods are becoming inadequate due to factors like renewable integration, extreme weather, and the rise of distributed energy resources (DERs). A report by the Energy Systems Integration Group emphasizes the need for utilities to shift from historical-based forecasting to time-based and scenario-based approaches. This evolution is necessary to address the complexities of modern energy demands and ensure reliable grid management.
Key challenges include the need for a mindset shift among utilities, as they must now consider intricate relationships between various factors influencing energy consumption. The report highlights the risks of uniform modeling, which can lead to misallocated resources and infrastructure investments. Ultimately, the report advocates for a comprehensive understanding of the evolving energy landscape, urging utilities to modernize their forecasting methods to avoid becoming bottlenecks in accommodating new energy demands and to support a successful energy transition.
