Building a real-time power outage map with Next.js on Vercel

Endeavour Energy, one of Australia's largest electricity distributors, serving over 2.8 million people, faced challenges with their outage map during storms due to high traffic and outdated infrastructure. To address these issues, they migrated their system to Vercel, implementing a headless setup with Next.js for the frontend and Supabase for real-time data management, while maintaining their existing CMS for content editing. This transformation resulted in significantly faster deployments, with sub-second page loads even during peak storm traffic and a five-minute data sync cycle, replacing the previous manual and unreliable system. The incremental migration approach avoided service disruption, and Vercel's preview deployments facilitated quicker stakeholder approvals. The new system allows Endeavour Energy to focus on customer needs, ensuring the outage map provides timely and accurate information during storm seasons.
