Efficient, flexible generation for a decarbonizing system
Sener designs and delivers combined cycle solutions that provide high-efficiency, low-emission power and heat, while preparing assets for the transition to renewable gases. Our expertise covers open and combined cycle configurations, multi- or single-shaft layouts, multiple fuels, and various cooling systems, always targeting best-in-class performance and reliability.
Our CCGT designs are conceived for fuel flexibility, CHP integration and future green hydrogen use. We apply proven methods—optimal shaft selection, advanced heat-recovery steam cycle design, and cooling choices (tower or air condenser)—to minimize heat rate and emissions while maximizing availability. With lifecycle service packages, we preserve performance as fuel blends evolve and operating regimes become more dynamic.
For decades, Sener has engineered complex thermal assets and hybrid plants, applying a technology-agnostic approach to deliver efficiency and lower CO₂. In Germany, together with GE Vernova and Bonatti, we are replacing two coal power plants with hydrogen-ready CCGT stations totaling 1.4 GW at Heilbronn and Altbach/Deizisau for EnBW—projects that include construction and long-term servicing. They will operate initially on natural gas and progressively adapt to burn 100% hydrogen from the 2030s, supporting EnBW’s goal of climate neutrality by 2035. This combination of engineering capability and delivery track record positions Sener as a trusted partner for utilities and industry.
We follow a structured methodology across four stages. In monitoring, we assess load, heat demand (for CHP), fuel logistics, grid interconnection and environmental constraints. During optimization, we simulate plant cycles, define shaft configuration, select gas turbines, and evaluate hydrogen-readiness (materials, combustion, and safety). Transformation executes EPC with rigorous QA/QC, SCADA integration and compliance testing. Finally, management sustains performance via predictive maintenance, degradation tracking and phased upgrades that enable increasing hydrogen shares without compromising safety or output.
Sener combines advanced modeling with materials and structural know-how to size critical systems correctly and plan upgrades over time. This approach reduces lifecycle cost, stabilizes efficiency under transient conditions, and accelerates the path from natural gas to renewable gases—keeping assets compliant and competitive in evolving markets.
Sener brings broad energy infrastructure experience in Spain, the Netherlands, Belgium and Morocco, integrating gas and power systems, large-scale terminals and hybrid plants that inform our CCGT delivery and interconnection capabilities.
We execute combined cycle power plants and CHP projects end-to-end: feasibility and conceptual design, detailed engineering, procurement, construction, commissioning, and long-term services.
