OCGT – Open-Cycle Gas Turbines

From shaft selection to auxiliary systems, we optimize OCGT layouts for response time, part-load efficiency and availability. Our designs accommodate multiple liquid and gaseous fuels and are engineered to fit continuous or discontinuous production regimes—maintaining stability and emissions within permitted values in demanding industrial contexts

Why choose us 

Sener brings decades of generation and industrial experience (particularly in oil & gas) to open cycle gas turbine power plant projects. Our teams have specialized in complex facilities that demand high flexibility while guaranteeing operation when integrated with existing industrial processes. This background underpins our ability to specify OCGT architectures that prioritize rapid start-up, grid code compliance and resilient performance across diverse duty cycles. 

How we work 

We start by characterizing demand (power, ramping, cycling) and site constraints. Using Sener’s modeling and engineering methods, we assess open-cycle options (multi-/single-shaft, fuel strategy, cooling choices) to match performance, cost and regulatory objectives. During execution, we deliver turnkey EPC—engineering, procurement, construction and start-up—with rigorous QA/QC, protections and SCADA integration. Post-COD, we provide monitoring and O&M services to sustain efficiency and availability under evolving operating profiles. 

Lifecycle value with future-ready engineering 

We design OCGT assets so they can evolve with market and process needs: upgrading controls, tuning for cycling, and integrating with plant-wide energy strategies. By coupling robust mechanical design with digital supervision and maintenance, we preserve output, lower lifetime costs and align with tightening environmental standards across the asset’s life.
