Onshore wind reaching grid parity - Why not top it?

According to MAKE’s recent study, onshore wind energy is very close to grid parity with conventional generation (see image). Despite the odds, mostly policy uncertainty that applies globally, the wind industry has managed to improve its cost competitiveness and is becoming a more and more lucrative investment. Us at Moventas play an important, dual part in this development: making wind energy cost effective throughout its lifecycle with reliable technology and preventive maintenance.

Our design philosophy is to make the gearbox itself as small, lightweight and reliable as possible to reduce cost throughout machinery lifetime. All our gearboxes are based on trusted, existing technologies that we have over thirty years of experience with. We continuously innovate together with our customers to reduce the cost, weight and size of the gearbox while maintaining low noise and vibration levels, as well as absolute reliability that affects the entire drivetrain of the turbine.

Our service philosophy is that prevention is better than cure. With the seven parametres that our CMaS condition management system uses, problems can be avoided before they occur. We service and repair our own and third party made gearboxes based on our knowledge and experience, with the help of our own as well as partner workshop network and field teams, both onshore and offshore.
 

"There’s no reason why the proportion of unplanned operations and maintenance costs should remain as high as it is now; 75%"
 

There are uncertainties we must live with and those we don’t. While weather poses a risk for wind energy, and always will, there’s no reason why the proportion of unplanned operations and maintenance costs should remain as high as it is now; 75% according to MAKE. Preventive maintenance can genuinely avoid surprising costs and unplanned interruptions to energy generation.

Onshore wind is already very close to grid parity and expected to meet it in most relevant wind markets during the next 2-3 years. Offshore wind still needs another 10 years to reach these levels. The main drivers towards grid parity for wind are scale, technical innovations and preventive service concepts – all underlying themes in our operations.

Utilizing these together as an industry we can even outperform conventional energy sources.
