For decades Gas Turbine World has been serving the global community of gas turbine designers, manufacturers, buyers and users through targeted peer-to-peer publications that address their need for practical information in easily referenced formats.

Our suite of printed publications comprises a bimonthly magazine complemented by the annual Performance Specs issue and the GTW Handbook, which has become an industry-benchmark project reference for power plant planning, evaluation and equipment procurement.


A practical information resource for reference during all phases of project planning and development from preliminary engineering and economic studies, bid specifications, evaluation and equipment selection, through plant commissioning and operation and maintenance.

Annually updated and timely, material covers new additions to production series gas turbines; latest OEM design performance specifications; estimated $/kW prices for simple cycle and combined cycle plants, annual project orders and installations around the world.

Used by application engineers, developers, owner-operators, consultants, buyers and specifiers working on new gas turbine projects and conversion or expansion of existing gas turbine assets.

Performance Specs

Updated OEM performance ratings of all gas turbine models  on the market for electric utility, oil & gas, petrochemical, industrial and marine power projects.

Separate reference sections, by application, for simple cycle, combined cycle, mechanical drive and marine operation. Listings are searchable by OEM name and model designation.

Performance data based on ISO standard conditions, but correction factors are provided to estimate adjustments  for non-standard site and operating conditions.

Widely used by application engineers, owner-operators, consultants  and prospective end users to select and evaluate gas turbine models best suited to project interests and requirements.


Founded in 1970, at the dawn of widespread industrial and electric utility acceptance of gas turbines for power generation, the magazine has been steadily reporting on development and deployment of gas turbines around the world in technical depth and real world context.

We write for a tough, demanding readership of practitioners: a mix of gas turbine designers, specifiers and builders, project application engineers, developers, owners, operators and consultants who share a common interest in the effective and profitable application of gas turbine power.

What sets us apart is our emphasis on the development and application of advanced technologies that extend the envelope of gas turbine performance in measures running the gamut from power rating, efficiency and emissions to plant reliability, operating flexibility, durability and life-cycle costs.

We take the job seriously – providing technical insight that addresses the practical interests of gas turbine engineers, buyers and end users.


GTW’s 10-year forecast is used by gas turbine OEMs, supply-chain equipment vendors and aftermarket product and service providers for market planning.

Updated annually to assess the likely impact of changing industry demand and supply on near-term and long range market potential, product sales, engineering, R&D, manufacturing, scheduling, staffing, budgeting and operations.

Deliverables include 38-page analysis and market sector data plus Excel file of baseline, upside and downside forecasts of OEM gas turbine model unit orders, year-by-year, and model market value.

Coal to gas conversions, profitably

TransAlta is converting its Sundance and Keephills coal fired plants to natural gas, with Emerson leading the design, procurement, installation and commissioning in the replacement of the full automation system for the converted projects. The conversions are part of a strategy that will see TransAlta transition to clean energy by 2025.

Keeping up with the cyber threat

The rapid adoption of connected power generation, transmission, distribution, and end-use assets are enabling utilities to move away from centralized power generation technologies, and towards distributed energy. But it is a shift that opens utilities to cyberattacks.
