Study on `Impact of Restructuring of SEBs’
The ARR for the three years thus worked out is as under:
Table: Aggregate Revenue Requirement for MSETCL
(Rs crore)
Particulars
2004-05
Un-audited
2005-06
April-March
2006-07
Forecast
Total revenue expenditure 1378.37 1402.64 1491.89
Return on equity capital 155.52 313.03 376.45
Aggregate revenue requirement 1533.89 1715.66 1868.34
Energy delivered (MU) 63808.73 64845.70 73359.28
Transmission charges (Rs/kWh) 0.24 0.26 0.25
It is seen from the above that transmission charges work out to 26 paise per kWh of
energy delivered, for the year 2005-06 and 25 paise for the period 2006-07. These
charges include return on equity amounts of Rs 313.03 crore for 2005-06 and Rs
376.45 crore for the year 2006-07. The ARR is awaiting approval of MERC.
Way forward
A few of the areas needing close attention in the immediate future are listed below:
i) The company should form a core group to identify its total requirements of all
relevant data. This should be attended to on top priority so that when the holding
company of MSEB takes action of implementation of the computerised
Information System MSETCL would have finalised its own requirements.
ii) Data Acquisition System (DAS) should be provided at EHV sub-stations to help,
inter-alia, collection of energy meter readings without any manual intervention.
Priority should be given in installing such systems in sub-stations feeding energy
in MSEDCL system at 11/22/33 kV level and in these sub-stations further
prioritising in interfacing the energy meters to the DAS. Presently, sub-stationwise
data of consumption of energy in auxiliaries, losses in transformers, etc., is
not available. MSETCL proposes to undertake this in immediate future.
Energy meters should be fixed on the incoming and outgoing of all EHV
transformers directly feeding energy in DISCOM’s 33, 22 and 11 kV network as
well as on associated 33, 22 and 11 kV feeders emanating from such
transformers (wherever not done already). This will help in tallying the
difference between readings of incoming and outgoing energy meters on
transformers (representing transformer loss, which typically should be of the
order of less than 1 per cent for EHV transformer) as well as tallying incoming
energy and sum of energy on the outgoing feeders flowing out to the distributing
company and the feeder supplying sub-station auxiliaries/colony (should be
nearing zero or negligible).
