@oetenergy.bsky.social
A non-profit software company aiming for fast and reliable energy transition globally. We empower energy planners and decision-makers with energy transition studies, flexible open-source platforms, and expert training and support.
@mapyourgrid.bsky.social is an open data and open-source initiative that empowers communities and individuals to map grid data worldwide — and assess its quality. All data must be verifiable by satellite imagery or street view imagery and mapped manually, by humans.
Better grid data = better energy planning. At #FOSDEM2026, Andreas Hernandez Denyer & François Lacombe showed why open and verifiable grid data matters. #MapYourGrid invites mappers & validators to help build it.

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...
#OpenSource
Open energy models are already used across the industry. Catalysing funding is more important than ever! At #FOSDEM2026, Maximilian explained how scaling open models requires redefining their value for the different audiences & measuring success by ecosystem growth & impact 🔗 youtu.be/txeHo2jj_RE
Finding the right #OpenEnergyModelling tool just got easier! The Open Energy Modelling Tool Tracker ranks open tools on development activity, source code interactions, and downloads.
