Executive Summary: GreenEnergy Corp struggled to balance the grid due to the unpredictable nature of renewable energy. We implemented a BigQuery-based forecasting system that predicts energy output with 88% accuracy, allowing for smarter grid management and reduced carbon emissions.
The Challenge
A regional energy provider transitioning toward majority-renewable generation. However, they faced significant hurdles:
- Unpredictability: Cloud cover or low wind caused sudden power drops.
- Legacy Systems: 30-year-old grid software couldn't handle real-time data.
- Penalties: Fines for failing to supply promised load.
Our Solution
We created a forecasting model on Google Cloud:
- Weather Integration: Ingested real-time satellite weather data.
- BigQuery: Analyzed historical production data against weather patterns.
- AI Forecasting: Predicted power output 12 hours in advance with 88% accuracy.
