Drumil Joshi, Monitoring & Diagnostics Analyst, Southern Power Company
- Drumil Joshi, a Monitoring & Diagnostics Analyst at Southern Power Company, fused his childhood fascination with electronics and a passion for data science to become the solo analyst for a $450 million renewable energy fleet.
- Inspired by a childhood in Mumbai where renewable energy was a daily necessity, Joshi saw renewable assets as living organisms waiting for algorithmic stethoscopes to reveal their hidden signals.
- Joshi overcame challenges in predictive maintenance by using reverse-labeling with physics, cluster-aware meta-learning, SHAP gatekeeper, and edge de-noise loop to improve ice prediction on wind turbines.
- His real-time oscillation detection system for battery storage prevented site trips, preserved energy capacity, and reduced mean time to repair, enhancing operational efficiency at Southern Power.
- Joshi developed the Operational Stability Index (OSI) to assess asset behavior, with real-world application preventing outages, saving revenue, and improving maintenance scheduling.
- His data-engineering architecture optimized with Azure Databricks, PySpark, and Airflow reduced manual work hours, improved dataset freshness, enabled faster ad-hoc analyses, and boosted asset availability.
- Joshi's approach to executive dashboards focuses on headlines, color-coded metrics, embedded stories, and ease of understanding, facilitating informed decision-making for non-technical stakeholders.
- One of Joshi's patents, the Air Quality Monitoring System Powered by Renewable Energy, improved energy yield at solar farms, demonstrating the future potential of self-powered environmental monitoring.
- In preparing for the future, Joshi envisions federated, multimodal learning in renewable energy systems using edge nano-ML kits, federated orchestration, multimodal digital twins, and LLM-powered root-cause chat for real-time insights.
- Joshi extends an invitation for collaboration to advance clean energy and emphasizes the importance of human-centric AI in making predictive insights accessible and actionable, aiming to inspire engineers to make greener energy solutions.
