transmission charges on this basis would work out to Ps 8.75/kWh. The Commission is also not in a position to consider the subsequent claim of KSEB for a total wheeling charge of Ps.147, since the supporting information called for by the Commission has not yet been furnished by the Board.
The Commission is therefore not agreeable to fix the transmission charges on the basis of the calculations furnished by the KSEB for working out charges for usage of the transmission system.
The Commission recognizes that there are different methods for working out the transmission charges, viz., pooled cost (postage stamp) method, contracted path method, MW-KM method, etc. In the particular case of import of 30 MW of power by Indal, as per the existing system configuration and operating conditions, most of the power would be received at Madakkathara 400 kV sub station. However, a part of the power, though small in quantum, may find its path over the other interconnecting lines. The situation may further change after the commissioning of the 400 kV Madurai-Thiruvananthapurm line, when a small portion of the power may find its path over this line also. This would mean that it would be difficult to distinctly identify the transmission path for transfer of 30 MW of power by Indal through the KSEB system. The Commission is therefore of the view that the most preferable method of determining the transmission charge is on the basis of the pooled cost of 220 kV transmission system in Kerala including the Kayamkulam transmission system. To this, the charges for usage of 110 kV transmission system from Kalamassery to Indal could be added. However, the KSEB was not in a position to furnish the cost details needed for arriving at the transmission charges on this basis.
Under the circumstances, the only option before the Commission is to arrive at the charges on the basis of the cost of a fairly new dedicated transmission system from Madakkathara to Alupuram, if constructed for transmission of 30 MW of power. The
