Service guarantees have traditionally been based on an amount of time that a manufacturer claims they will work for, typically 97%.
The new Vestas product will take this a step further and take into account the amount of energy a turbine would produce at certain times of the year.
Maintenance would be planned for times of the year when wind is low.
Compensation for unexpected outages would then be calculated more accurately by taking into account the average wind speed that could be expected at that time of year.
For example, a customer would receive more money for a turbine being down in January, when winds are high, than they would in July, when they are lower.
The product will be available for both onshore and offshore turbines, in all markets where Vestas operates.
