| Abstract | This paper presents a methodology composed of two parts to facilitate the decision making process of hydrothermal generation companies (gencos) during the negotiation of bilateral contracts. In the first part is established a procedure for determining the risk of deficit of Energy Availability (EA) introduced by a new contract under negotiation given the uncertainty in the concept of ensured energy (EE) of hydro units. In the second part, the required buyer modulation along the period of contracts due to load seasonal variation is analyzed in terms of the impact on the gencos risk to unfavorable prices (or negative spot exposition) given the uncertainty in spot prices. Furthermore, the impact on the risk of negative spot exposition is also analyzed with respect to the offered monthly flexibility option to the buyer for compensating unpredicted load variations. Results show that using this tool, gencos can have important information during the negotiation process. This information includes obtaining the risk of EA deficit, the more convenient contractual price, the risk of negative exposition to the spot market price and the maximum convenient flexibility conditions. Several numerical cases are presented to illustrate how this tool supports the decision process during the negotiation of the contractual conditions. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
