The company operates three core solution areas — Customer Solutions, Business/Technology & Operations Solutions, and Grid Solutions — plus a specialized Water Loss Consulting practice and recurring data/API products (Business Energy Advisor, Battery Forecast Database, Energy AdVision, DSM Evaluation Library).
