Case Study: Fysiko Aerio Ellados improves natural gas demand forecasting accuracy with Ex Machina

Attiki Gas Supply Company improves daily gas forecasting accuracy with Ex Machina for 330,000 households

Fysiko Aerio Ellados, formerly Attiki Gas Supply Company, is Greece's largest city-gas distributor. Its core challenge was accurately forecasting daily natural gas demand for its regulatory capacity declarations, as errors resulted in significant financial penalties. The demand was highly sensitive to local weather, and the company needed a partner to provide high-quality, high-resolution weather data to feed its machine learning forecasting system. It engaged Ex Machina for this weather data service.

Ex Machina built a precision weather data pipeline by identifying optimal monitoring points across the Attica basin and providing clean, multi-year historical data for model training. They then delivered a daily automated feed of forecast-ready weather data. This solution from Ex Machina provided the reliable data foundation needed, leading to improved forecast accuracy, direct cost savings from reduced imbalance charges, and greater operational confidence for the customer. The partnership has been live since 2016.
