Abstract | Diesel generation units are not often considered for replacement before they reach the manufacturer's recommended life, and sometimes only after it runs to failure. Although this can take better advantage of the unit life, it may not be the most cost effective strategy considering the fact that aging units often have higher operation and maintenance costs, and undesirable reliability consequences. In order to allow financial retain/replace decisions to be made; this paper proposes a cost effectiveness analysis method. Each generation unit under evaluation is given an asset health index (AHI), which is defined as the ratio of the NPV of running a unit to end of life over the NPV of immediate replacement. AHI is a self-explanatory quantitative indicator of the cost effectiveness for unit replacement. In-house software named asset health index calculator (HI) has been developed and an AHI has been produced for every diesel generation unit in service in the BC Hydro non-integrated areas (NIA) for the future 20 years, so planners can easily foresee when and which units should be replaced in this planning window. A performance evaluation of the generation units is also required by not discussed in this paper. The development of the AHI and the performance evaluation allow proactive fleet capacity planning and justifiable asset management expenditure. As an effective planning tool, the proposed AHI method can be extended to the evaluation for other aging assets |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
