About The Customer
A2A is the largest Italian multi-utility company. The company operates in the sectors of energy production and distribution, environment, water, and electric mobility. A2A was faced with the challenge of modernizing their Chivasso power plants to become more responsive to changing grid demands and to boost productivity in a competitive market. The company needed to reopen the plant with compelling improvements to efficiency and a lower impact on the environment. Achieving the lowest emissions compliant load level was a critical success factor for A2A to compete successfully in the ancillary services market space, particularly in their location.
The Challenge
A2A, the largest Italian multi-utility company, was faced with the challenge of modernizing their Chivasso power plants to become more responsive to changing grid demands and to boost productivity in a competitive market. The company needed to reopen the plant with compelling improvements to efficiency and a lower impact on the environment. Achieving the lowest emissions compliant load level was a critical success factor for A2A to compete successfully in the ancillary services market space, particularly in their location.
The Solution
GE worked closely with A2A traders, engineers, and production team to prove that the Chivasso plant could be improved to succeed in a competitive market. The team began by installing GE’s Operations Optimization software to nine 9FA gas turbines at four combined-cycle power plants in Lombardia in northern Italy, and, at the Chivasso plant, GE upgraded two 9FA gas turbines with GE’s Dry Low NOx 2.6+ combustion technology. GE’s Operations Optimization solution was applied to gather machine sensor data, apply analytics and help A2A plant management understand how to engage GE’s controls software to better react to market conditions, lower operating costs and reduce the plant’s environmental footprint.
Operational Impact
  • A2A now has the necessary visibility and operational flexibility to bring the plant online effectively and economically, responding to dynamic market conditions.
  • GE’s solution helped achieve a 65MW per GT minimum load level — the best in the GE 9FA fleet.
  • The Operations Optimization solution enabled load ramping at up to ±50 MW/min, 2.5 times the normal rate, permitting A2A to react quickly to market demands.
  • A2A’s power block is now producing hundreds of hours of electricity since coming back online in November 2015 and is able to be competitive in their market.
  • By increasing plant responsiveness, A2A is better able to meet fast-changing grid demands.
Quantitative Benefit
  • Achieved 65 MW per GT Min load level
  • Minimized fuel start costs
  • Load ramping at up to ±50 MW/min, 2.5 X normal rate
