Helping ESG scale up their capabilities and implement digital changes faster

The Mission

ESG Global, a leading provider of energy software solutions, faced a critical challenge: their existing energy billing platform was aging and unable to handle the new SMETS2 smart meter data reads. With the UK energy sector rapidly transitioning to smart metering, ESG Global needed a modern, scalable, and efficient solution to process real-time meter readings and ensure compliance with industry standards.

ClearSky Logic was engaged to overhaul and modernise the billing system, ensuring seamless integration with SMETS2 data and improving the overall performance, scalability, and reliability of the platform.
