Overview
Ostrom in Berlin delivers 100% green electricity to German households through a subscription that charges a flat monthly fee and provides electricity at market cost. The service includes two tariffs—SimplyFair for predictable bills and SimplyDynamic with hourly, real-time pricing using smart meters—accessible via a mobile app that shows consumption and lets customers adjust tariffs in real time. Ostrom differentiates itself by aligning its incentives with customers’ energy use, promoting demand-side flexibility, and building Germany’s largest Virtual Power Plant to coordinate decentralized assets like EVs for grid stability. Its goal is to lower energy costs for customers, accelerate smart-meter rollout, and scale a VPP to enable a cleaner, more flexible energy system.
