A space-weather analysis system for power grid operators: it predicts grid failures triggered by solar flares and serves up 7-day forecasts, risk thresholds and recommended actions, applying data engineering and ML to critical-infrastructure resilience.
What carried this one is that it does not stop at a prediction — it stops just short of a decision. Seven-day forecasts plus risk thresholds plus recommended actions means the team thought about what a grid operator does after looking at the screen, whereas most analytics entries end at a dashboard. Running a full pipeline from data engineering through ML on the free tier also makes the platform itself look capable, which is the quiet point of a Free Edition hackathon.
