Executive Summary The Petitioner owns and operates an installed
power generation capacity of 420 MW with two units of 210 MW
each. Historically the generating units have been operating at
much below their potential because of transmission constraints
and frequent tripping of transmission lines. However, after
2006-07, the plant has shown an impressive performance and now
both the units are able to dispatch simultaneously.
Table 1 provides the performance of the
generating units during the period 2000-2009.

Data taken from
the letter of GM TTPS
The non-tariff income was Rs. 419.5 lakhs during the FY 2008-09
The sum of fixed
and energy costs gives the total revenue requirement of the
company for the FY 2008-09. The revenue requirement less other
income will be the revenue to be raised through tariff. This has
been worked out in the Table 5 below:

estimated a revenue requirement of Rs 473.98 Crores after
adjusting for its non-tariff income and derived the following
fixed and energy components of tariff:
