United, by nature: Siemens Wind Power and Gamesa

United, by nature: Siemens Wind Power and Gamesa

The Current Situation

Global onshore growth

Today, the critical need for sustainable sources of energy has become a pressing global issue. Over the last few decades, onshore wind power has emerged as the favored solution, and has developed into one of the most valued sources of renewable energy worldwide.

Onshore wind power contributes to local economies and creates jobs, with projects being developed by an increasingly diverse range of interest groups, from private individuals to large corporations. As high demand continues, considerable technological advances have been made. As a result, onshore wind has become one of the most competitive and cost-effective renewable energy sources, accounting for 97% of global wind power installations in 2015.

Onshore Wind power in numbers

Onshore Wind power is a well-established source of energy that provides clean, sustainable power to many countries around the world. Asia has the greatest number of installations, followed by Europe and America.


Understanding the different markets

The onshore wind industry is not without its challenges. Different locations, environments, and country regulations create a growing range of aspects to consider when planning and executing a wind power project.

When undertaking an onshore wind power project, often complex factors come into play – how is the local grid connection? Are there political restrictions or local laws that could complicate the development?


In addition, localized environmental restrictions such as turbine height, noise level, and wildlife endangerment all need to be taken into account. Further, different locations offer varying degrees of wind, which also change from hour to hour.



Unique needs – tailored solution

Onshore success depends on solutions that meet divergent needs – often a tailored response is needed. No matter how complex or challenging the site, Siemens is able to optimize it for best performance by leveraging every single step of a project’s lifecycle.

Onshore Direct Drive wind turbines

Innovations throughout a project’s entire lifetime

It’s by listening to stakeholder feedback and interests that successful onshore solutions are developed. More than 30 years of experience has given Siemens peerless insight into the industry, which is integrated into successful 360-degree onshore solutions.

A versatile, thoroughly researched product portfolio and a global network that extends throughout 190 countries allow Siemens to answer the unique needs and expectations that can arise anywhere in the world with local expertise.


Siemens matches unique customer requirements further with extended-scope solutions. Before considering financing and the actual construction of a wind power plant, the ideal site layout has to be defined. We analyze the site with data collection and modeling according to technical standards and specific site conditions apply local expertise and recommend the optimized layout. Additional solutions include project management consultancy, financial solutions, grid access, custom service solutions, and general support throughout the lifetime of a renewable energy project. 


Terabytes of data collected and analyzed during operation drives innovations, and all members of the supply chain work in close cooperation to ensure that feedback is implemented into future developments – whether a new wind turbine or improvements to an existing product. Applying this data for immediate ROI, our Remote Diagnostic Services (RDS) encompasses a set of service functions to increase production and optimize performance through monitoring

How technical features improve turbine performance

Two platforms for every opportunity

Two main wind turbine families, geared and direct drive onshore wind turbines, serve all IEC wind classes and respectively satisfy the capacity and positional constraints unique to each onshore customer’s needs. We are continuing with our heritage of innovation with the new OptimaFlex concept for onshore direct drive turbines. OptimaFlex represents an entirely fresh approach to wind power that gives our customers unprecedented levels of flexibility at every stage of the project lifecycle.


Location-specific innovations also meet individual customer needs – such as the de-icing system, which allows turbines to operate in harsh ice conditions and avoid shutdown events from cold. Or the noise Restricted Operation, a functionality that allows turbines to switch from normal to low noise operation as necessary for local regulations – optimizing maximum power output to noise emission trade-off.


Individuals committed to technological progress

Special solutions come from special people. Experts all over the world are constantly working on improving current technology and finding new ways to make onshore wind power even more attractive. Find out more about what Siemens employees do to support the rise of green energy.

Per Egedal introduces the power boost function.

Engineers such as Per Egedal work to ensure that we’re pushing the boundaries of what’s possible by anticipating customer needs. Per’s data tool helps customers make challenging investment decisions by using big data and giving a very precise prediction of the increased output you’ll see after installing the power boost function.

Driving down costs

But it’s not only about increasing output. By reexamining every facet of the process, Liann Graakjaer, Kim Joergensen, and their teams don’t just keep transport costs level – they reduce them. Thanks to these teams, through cost savings the turbines start to give returns before they’ve even completed their first revolution.
