L.T.S.A.

Maintenance strategies, due to the constant challenges of the power market, are becoming even more a key factor of success for Power Producers.
The clear evolution of the energy market has been changing the characteristics of the scenario. Liberalisation, competition, floating electricity prices have been making power generation more of a profitably run business than a state-subsidised infrastructure. Likewise, maintenance strategies have moved from a preservation-and-protection concept to the asset management and optimisation.

With this respect, Power Producers need to adopt carefully personalised global maintenance strategies covering the entire lifecycle of the power plant.
