(2.) THE generating station having a capacity of 540 MW is located in the State of Himachal Pradesh and was declared under commercial operation on 1.5.1994. The tariff of the generating station for the period from 1.4.2004 to 31.3.2009 was approved by the Commission vide its order dated 9.5.2006 in Petition No. 39/2005 and was revised by order dated 5.2.2007 in Review Petition No. 64/2006 (in Petition No. 39/2005). Aggrieved by the said order, the petitioner had filed Appeal No. 84/2007 before the Appellate Tribunal for Electricity (the Tribunal) raising the issues namely, (a) Allocation of additional capitalization for the period 1.4.2001 to 31.3.2004 towards debt and equity(b) on adoption of new debt equity ratio, the calculations of gross loan, return on equity and interest on loan have been completely distorted; and (c) Error in calculation of depreciable value in respect of unclassified land.

Accordingly, the Tribunal by order dated 5.2.2008 directed the Commission to pass consequential orders. The relevant extract of the order dated 5.2.2008 is as under: "Having considered the whole matter we allow the appeal only to the extent of the two grounds mentioned above and set aside the impugned order and remand the matter to the CERC for reconsideration of the appellants claim. "1. With regard to the apportioning of the additional capitalization (including de -capitalization and FERV) for the period 1.4.2001 to 31.3.2004 in the same debt -equity ratio of 68.99:31.01 as admitted in the previous tariff period and 2. With regard to the adoption of new debt equity ratio, the calculations of gross loan, RoE and Interest on loan. The Commission is at liberty to give further relief which will be consequent upon the Commission decision on the two above issues. The appellant as well as other respondents will be at liberty to challenge the order that CERC may now pass consequent upon the present directions."
(3.) BASED on this, the only issue considered by the Tribunal in the said appeal was the error in the calculation of depreciable value of unclassified land and the same was dismissed by the Tribunal vide judgment dated 23.12.2009.
