thermal power development - Infraline

Central electricity authority Annual Report 2009-10
3.8.4 Advice to CERC on connectivity
of small hydro projects as well as
on different transmission related
issues
‣ The CERC Regulations do not allow direct
connectivity to ISTS for power stations of
capacity less than 25 MW. It is expected
that hydro stations of less than 25 MW
would first get connected to the STU. It was
brought to the notice of CERC that STUs
of States like Sikkim, Arunachal Pradesh,
Himachal Pradesh etc. are not equipped to
provide connectivity to generating stations
to the State Grid and such a dispensation
would jeopardise the development of IPP
hydro projects. CEA has already prepared
Master Plan for Sikkim, HP, Uttaranchal
etc. for providing direct connectivity to
a number of HEPs in the range of 90-250
MW. CERC was advised to review their
regulations for Long Term Access.
3.8.5 Vetting of price variation in bills of
transmission works under Kabul-
Phul-e-Khumri transmission system
in Afghanistan.
3.9 Study, analysis and formulation of
policies on specific issues relating to
transmission
3.9.1 Long Term Planning Studies
Transmission system planning studies
were carried out to evolve a composite system
for evacuation of power from generation projects
envisaged beyond 11 th Plan. Studies were carried
out to identify long-term system strengthening
requirements in various regions/States. A list of
studies carried out to evolve long term perspective
plan are as below:
‣ Transmission System for Evacuation of
Power from Yeramaras (2x800 MW) &
Edlapur (1x800 MW) Generation Projects
of KPCL near Raichur in Karnataka.
‣ Establishing connectivity to Yelahanka
2x500 MVA,400/220 kV S/S and Additional
ISTS In-feed for Bangalore.
‣ System studies for Strengthening/
Restructuring of Bangalore 400kV ring
arrangement.
‣ VIP Strengthening connectivity of SV
Chatram 400 kV S/S of TNEB.
‣ Transmission System studies for evacuation
of power from Udangudi TPS (2x800 MW)
project.
‣ Power system studies were carried out
to evolve the transmission system for
evacuation of power from generation
projects envisaged during 12 th Plan for
NEP.
‣ System strengthening scheme of Haryana,
keeping in view various thermal projects.
‣ System strengthening scheme of Rajasthan,
keeping in view various thermal projects.
‣ System strengthening scheme of Punjab,
keeping in view various thermal projects.
‣ Transmission planning studies for
strengthening of Northern Region network
i.e Northern Regional System Strengthening
Scheme – XXI, XXII, XXIII.
‣ Transmission system associated with the
Tilaiya Ultra Mega Power Project (4000
MW) in Jharkhand, Nabinagar (1000MW)
of Railways and NTPC, Barh-II (1320
MW) and IPPs in Jharkhand, Orissa, MP,
Chattisgarh and Maharashtra.
‣ System Studies for Sasan / Vindyachal pool
connectivity / Power evacuation system
from Rihand-III TPS (2x500 MW).
3.9.2 Short Term Planning Studies
System studies were carried out for
evolving transmission system for evacuation
of power from generation projects anticipated
during 10 th Plan. A list of the studies carried out
is given below:
