Building a Lightweight Feature Store for Electricity Grid Forecasts with Polars
Robin Troesch

Get a firsthand look at how we built a lightweight feature store to accelerate electricity grid forecasting. We’ll cover our decision process, design choices, and implementation using Polars and Google Cloud Storage. Expect lessons learned, real-world bumps, and a clear view of the costs, trade-offs and benefits of our solution.
