The number of energy communities in Austria is growing rapidly. Their operation primarily relies on standardized processes for data collection, communication, and billing. Beyond collective accounting within the community, further optimizations—such as maximizing self-consumption and minimizing grid feed-in—are severely limited by the lack of real-time data. Accessing real-time energy data directly via the smart meter customer interface and aggregating it at the community level enables more precise load balancing and better utilization of renewable energy sources. This paper presents the Community Aggregation Tool, a modular software solution designed to collect, harmonize, and aggregate real-time energy data from diverse metering systems and protocols. The tool integrates multiple data sources and leverages existing open-source solutions for its implementation. Initial deployments in selected energy communities demonstrate its potential to address key challenges, such as limited data granularity and the heterogeneity of household devices.
