thermal power development - Infraline

Central electricity authority Annual Report 2009-10
It can be seen from the above data that the
number of cases received for PTCC route
approval have increased by 38%. The total
circuit kilometers of the EHT lines (Total
length of 220 kV, 400 kV & 500 kV HVDC)
for which PTCC route approval has been
accorded, has increased by 15%.
4.8.1 Computerisation of PTCC
In order to cut down the processing time
of PTCC route approval, a proposal for the
computerization of PTCC process was forwarded
to Ministry of Power for sanction and is under
process by MoP. The estimated cost of the
scheme is Rs. 1466 Lakhs. A budget provision
of Rs.100 Lakhs has been kept for the year 2010-
11 towards appointing the consultant.
4.9 Establishment of Load Despatch
& Telecommunication Facilities
for Power Sector
All the five Unified Load Despatch
and Communication (ULDC) schemes are in
operation for about last 8 years. Unified Load
Despatch Scheme Monitoring Group (USMG)
which has been inter-alia entrusted the work of
formulating minimum standard requirements
for ULDC scheme (phase-II) for replacement /
upgradation / expansion and O&M of the
ULDC system in Northern Region, CEA has
been providing technical input to the Group /
Committee.
4.10 National Load Despatch Centre
(NLDC)
The National Load Despatch Centre
(NLDC) was commissioned last year and the
same has been running successfully.
4.11 Frequency Allocation Coordination
for Microwave
and Power Line Carrier
Communication (PLCC)
CEA co-ordinates and follows up with
Wireless Planning and Co-ordination (WPC)
Wing of Department of Telecommunications
(DoT) to accord frequency allocation for
PLCC system of new power transmission
lines and VHF/ UHF / Microwave systems of
power utilities.
As per the WPC, the frequency band 2.3-
2.4 GHz used for microwave communication
in the ULDC schemes for Load Despatch
systems is to be vacated. CEA examined the
case and has been providing required technical
input to the Ministry of Power.
During the financial year 2009-
10, frequency allocations for PLCC for
"Electricity is life: Conserve it."
