Under an LTSA contract, Ansaldo Energia provides a number of winning features.

Guaranteed availability on the Power Generation groups
Clearly, availability directly and heavily impacts on the customer's return of the investment. Under an LTSA, Ansaldo Energia can take up to the full responsibility of the availability and productivity of the power train.

Remote Monitoring & Diagnostics
Remote Monitoring & Diagnostics (RM&D) is the base for predictive maintenance. In Ansaldo Energia's experience, it is demonstrated that swift problem solving and smart decision making are facilitated when expertise, pulled together from different Engineering & Field Service Dept's, can check in real time the trends of the key operating parameters and consequently simulate different scenarios (e.g.: design and off-design). The value added by Ansaldo Energia Service is no longer delivered exclusively during overhauls, but also by Ansaldo's ability to monitor the power plant components throughout their operating lives.
Ansaldo Energia developed the TVA System as the most suitable tool to collect critical data, assess operating conditions, store information and deliver it to a remote location for examination by expert maintenance technicians. Such a RM&D tool therefore enters into a troubleshooting cycle which provides swift, proper answers to the Customer as a valuable decision making support.

Management and Pooling of Spare parts
Ansaldo Energia's stock management is becoming a cornerstone of LTSA productivity. Parts are classified within categories, each of which is treated differently according to availability, replenish and repair criteria.
It is part of Ansaldo Energia's LTSA approach to provide customers with several different proposals for spare parts management.
Considering the high economic value of several strategic and non-strategic spare parts, stock management becomes a significant factor in the lifetime cost of a power plant. Ansaldo Energia has invested in advanced statistical software tools which allow optimisation of pooling across a large customer base. The outputs are directly connected to the supply chain management system, thus guaranteeing a fast execution response and allowing a case-by-case sizing of the total stock on which the pool is based. Not less than 99,99% availability level of strategic parts is granted in any prospective scenario. For an extensive reference list of LTSA, please refer to the relevant add-on.
