Texas-based Fractal EMS has released version 23.9 of its energy storage and hybrid technoeconomic modelling software, Fractal Model.

Fractal Model is a techno-economic system modelling tool for energy storage and hybrid projects. It provides investment grade analysis while simulating performance, degradation, warranty, costs and revenue to optimise the economics of energy storage and hybrid projects.

The release includes features that empower users with the latest benchmark curves for energy storage procurement and construction expense. It also includes new features to sensitise availability impact on project returns. The availability impact on storage returns can be more significant compared with solar and wind projects. Finally, the release also provides users an intuitive and transparent mechanism to perform deep diligence on storage dispatch optimisation.

“The Fractal Model strives to be the most robust energy storage and hybrid modelling software, properly balancing physics and financials, to enable real-world technoeconomic analysis and due diligence of battery storage and hybrid projects,” said CEO Daniel Crotze. “Our no-black-box approach allows auditing to support investment decisions, project finance and tax equity. We’ve been fortunate to have a sophisticated global client base over the years that has allowed us to make cutting-edge advancements as the markets and technology changes.”

The next software release is scheduled for December and will feature capability to model Ercot’s new ECRS service in Fractal Model. The release will also feature additional modules for hydrogen-based technologies and long duration storage technologies.

Fractal EMS ( is a vertical, onsite controls platform that includes controls, networking, scada, historian, integration and HMI with optional monitoring, maintenance and bid optimisation. It provides full command, control, monitoring and management for storage and solar projects. Fractal has 5GWh in operation and over 16GWh of awarded projects.
