“8.7 We have considered the submissions of the learned counsel appearing for the Appellant as well as Respondent Nos. 3, 4 & 6 relating to this issue. The main issue for the rival contentions is consideration of the zero date for the start up of project work and the time period considered for completion of the generating units for CoD. While the Appellant has repeatedly argued for zero date as date of final investment sanction i.e. 16.06.2008, the Respondents have contested that the project gets started immediately after the LoA and timeline to be considered for commissioning up of the project as stipulated in the LoA gets reckoned from the date of LoA. In the present case, being a project of National Importance, envisaging power supply to DTL for Commonwealth Games, 2010, the preparatory works for investment approval and placement of LoA was required to be expedited to meet the deadline matching with the commencement of Commonwealth Games. It is significant to note that with this clear objective for the project keeping in mind, the DVC Management approved the implementation of the project with the investment approval on 30.04.2007 stipulating completion period of 36-38 months for both the units in order to complete the project in all respects and to start generation well before the Commonwealth Games. Further, as a general practice, the projects being implemented by CPSUs’ or other utilities get similar approvals by their respective Board with specific timelines for completion. The final investment sanction by GOI/CPSU Board in fact, reduces to a mere formality and cannot be considered as zero date as being claimed in the present case. Admittedly, if one considers the date of final investment sanction by MOP/DVC (16.06.2008) as zero date, the project cannot be completed in two years and three months and resultantly, cannot yield in power supply to DTL as envisaged from the project for the Commonwealth Games (October, 2010). Hence, we find no legal infirmity or ambiguity in the impugned order of the Central Commission so far as the issue of computation of completion period of the project considering the zero date from LOA (27.07.2007) is concerned.”
