Without transparent energy planning, the lights could go out A team from Open Energy Transition discusses the benefits of open energy system modelling in assessing resources, including energy storage of varying durations.

Open models should be the standard in energy storage planning. We conducted a study with Form Energy showing that multi-day storage can cut curtailment, lower prices, and boost resilience.

Energy models are critical infrastructure. If licensing terms or vendor priorities on proprietary software change, who controls Europe’s energy planning backbone? Open models strengthen #DigitalSovereignty, transparency & continuity: www.openenergytransition.org/posts/protec...
