Case Study: A2A achieves 65 MW/GT minimum load and rapid ±50 MW/min ramping with GE Digital Operations Optimization

A2A - Customer Case Study

A2A, Italy’s largest multi-utility, needed to modernize its Chivasso combined‑cycle power plant to lower emissions, cut operating costs and become responsive enough to compete in the ancillary services market. A2A engaged GE Digital, deploying GE’s Operations Optimization software and upgrading two 9FA gas turbines with GE’s Dry Low NOx 2.6+ combustion technology to prove the plant could meet stricter load and environmental requirements.

GE Digital implemented Operations Optimization across nine 9FA turbines (four combined‑cycle sites) to collect sensor data, apply analytics and drive advanced controls. The solution delivered measurable gains: a 65 MW per‑GT minimum load (best in the GE 9FA fleet), load ramping up to ±50 MW/min (2.5× normal), reduced fuel start costs and hundreds of hours of stable operation since the plant returned online in November 2015, enabling A2A to respond quickly to market demands.
