Chapter 1. Annual Report on Technical Performance of Kulhal HEP
1.1 Overview
1.1.1 The petitioner in compliance of the Regulations 12 and 13 of UERC (Terms and
Conditions for determination of Tariff) Regulations, 2011 is providing
information with regard to the operational performance related to technical
parameters of Kulhal Hydro Power Station.
1.1.2 The information provided in this chapter relates to actual and expected
performance in FY 2011-12, FY 2012-13, FY 2013-14, FY 2014-15 & FY 2015-16.
The operational parameters considered are:
(a) Gross generation
(b) Auxiliary consumption and Transformation losses
(c) Plant Availability factor (PAF)
1.2 Power Station Description
1.2.1.1 The Kulhal Power Station with an installed capacity of 30 MW (3X10 MW) is
located on the downstream of the Asan Barrage at a distance of 4.0 km on the
power channel which takes off from the Asan Barrage. The Power Station was
commissioned in the year 1975. The surface Power Station comprising 3 units
of 10 MW each with Kaplan turbines is located on the power channel which
terminates in 39.2 m wide and 6.9 m deep fore bay. There are three 30 m long
and 4.5 m dia. steel lined penstocks, one for each unit. In case of tripping of
machines full discharge gets bye-passed through a 21m wide gated bye pass
channel. The water from the tail race flows towards Khara Power Station in UP.
The Kulhal Power Station is a low head scheme located on power channel with
a design head of 18 m and design discharge of 198 cum.
1.2.1.2 There are three generating units having vertical Kaplan turbine directly coupled
with synchronous generator. The turbine output is 10.4 MW for a rated net
head of 18 m. The generators are designed for a nominal output of 11.1 MVA
with lagging power factor of 0.9 and class “B” insulation.

1.2.1.3 This Power Station was commissioned in the year 1975. Due to continuous
operations of machines for past 38 years, efficiency of machines has substantially
decreased despite the regular and timely maintenance of the machine by
Petitioner.
1.2.2 Salient features of the Power Station are provided in form F 2.3 of this petition.
1.3 Energy Generation
1.3.1 The actual Gross and Net Energy generated in FY 2011-12, FY 2012-13 & FY
2013-14 is given in the table below:

1.3.2 The Gross and Net Energy expected to be generated in FY 2014-15 and FY
2015-16 is given in the table below:

Kulhal HEP November 2014 Page 3
1.3.3 From the above table it is evident that gross generation in the FY 2014-15 is
expected to be more than the design energy of the Power Station but it is
expected to be marginally less than DE in 2015-16.
1.3.4 The auxiliary and transformation losses in FY 2014-15 are expected to be more
than the normative level. However, the petitioner is investigating the reasons
for higher losses and will take appropriate steps to bring them to the
normative level.
1.4 Plant Availability Factor
1.4.1 The recovery of the Annual Fixed Charges is dependent on the Plant
Availability achieved by the Power Station. The principle for recovery of fixed
charges on the basis of the availability achieved by the plant has been
introduced by the Hon’ble Commission by its regulations UERC (Terms and
Conditions for Determination of tariff) Regulations, 2011 from the FY 2013-14.
The petitioner has started computing this factor as per the provisions of the
above regulations from FY 2013-14

1.4.2 PAFM: Kulhal Hydro Power Station is likely to achieve the normative plant
availability factor determined by the Hon’ble Commission for the FY 2014-15
and FY 2015-16 as well.
The PAFM fixed by Hon’ble UERC during FY 2013-14 could be achieved
through optimum availability of water in the river and performance of Ichari

dam,Dakpathar Barrage & Asan Barrage and no major problems faced in the
machines resulting in better availability of machines.
The Petitioner does not seek any deviation in NAPAF from the norms as
determined by Hon’ble Commission in its order dated 03.09.2013.
