Case Study: Green Mountain Power achieves real-time customer insights and 10x faster analytics with Cloudera

Green Mountain Power reducing utility rates with improved customer insight and operational visibility

Green Mountain Power, Vermont’s largest utility serving 80% of residents and recognized for energy innovation and high customer satisfaction, faced a major data challenge after deploying advanced metering infrastructure: meter reads increased from one per day to 96 per day across multiple channels (480 reads per customer daily). The company’s legacy Exadata platform couldn’t scale or deliver timely analytics to meet operational, billing, and customer-insight needs.

GMP implemented a Cloudera modern data warehouse to store, process, and analyze IoT meter data in real time, enabling dashboards and self-service analytics for executives, operations, energy management teams, and customers. The platform now handles ~150 million meter readings daily, accelerates ETL 10x, cuts report times from 30 minutes to 30 seconds, supports personalized billing insights and faster demand response, and delivered operational gains such as identifying and disabling underperforming turbines.
