Complete Coal Fired Steam Turbine Power Plant (350 MW) 65'000 operative hours

Description

a 350 MW subcritical coal-fired power plant, commissioned in 2012 and remained operational 7 years until 2022.

Equipped with modern environmental controls, it played a crucial role in Chile’s electricity generation before its retirement.

The unit is state of the art design rules and allows to acheive 37% efficiency.

The chosen solution ensures high reliabilility and high availability of baseload power, providing some flexibility by allowing turndown capability to 40%.

The 350 MW power block is designed to deliver reliable, scalable, and efficient energy production by repurposing the infrastructure of a former coal power plant.
This innovative approach maximizes value from existing assets while supporting the global transition to sustainable energy.
