Despite
having a rich potential in hydro, Mizoram is not having its own power generation
worth mentioning. At present, there are 22 (twenty two) isolated Diesel Power
stations scattered at various places and 9(nine) Mini/Micro Hydel stations in
operation. The above total installed capacity of diesel Power Station is 26.14MW
and Mini/Micro Hydel Station is 8.25MW. As per 16th Electric Power
Survey of India under CEA, Government of India, the restricted peak load demand
of the State during the year 2002-2003 is 102 MW. Against this, an effective
capacity of about 16MW from Diesel Power Stations and 6MW from Hydel Stations is
available from local generation at present.
The
requirement of power is mostly made up by importing energy from center sector,
generating stations and Mizoram share of 8MW from Rokhia-II in Tripura through
the North Eastern Grid looked after
by the Power Grid. In all, total availability of imported power rarely exceed 45
MW during peak hour. Therefore, there is a big gap between demand and
availability of power. The daily peek short fall at normal condition accounts
for about 34% to 40%.
Demand
for power arises out of many factors such as population growth, rising incomes,
urbanization and Industrial growth. If the state is to kick start its industrial
sector, there will have to be much faster power supply growth. If the power
deficit is to be brought to manageable levels, power supply has to grow along
with growth of annual demand in the future and if industry is to grow in Mizoram
the requirement of power would be significantly higher than 145 MW.

POTENTIAL
: POWER OPTIONS
-
Grid Power has its
downside because of uncertainty of supply and poor transmission etc. but
grid-based power is cheap. Hence grid-based power is now available. Therefore,
the strategic advantages of grid-based power should be realised, and Government
of Mizoram endeavour to push for an improvement in the transmission mechanism of
power, and even more power from the grid. The government also endeavour to
augment and improve the transmission systems so as to improve the reliability
and availability of power supplies.
-
Mizoram is being a hilly
terrain, steep, and separated by rivers flowing either to the north or to the
south, creating deep gorges between the hill ranges, there are potential for
small and seasonal small hydro project. Small hydel plants thus have advantage
of modest front-end costs and benefits that are not far off in time. It is
claimed that Mizoram state has as many as 73 possible locations for small hydel
plants. The state government have 11 projects sites cleared already, that can be
implemented subject to availability of fund. The Ministry of Renewable Energy is
offering a subsidy of 50% on the project cost in case of small hydel plant upto
3 MW of capacity.
-
Solar Energy is one of
the potential areas for investment in Mizoram. About 58 villages are electrified
by Solar energy in Mizoram. However, an attempt should be made to increase this
number with the help of International energy and environmental devilment
agencies.
-
The state Government is
actively considered investing in a thermal power plant which will relieve the
most urgent short term need and besides help to cope with peak demand.
-
Furnace oil based power
plant could be built as part of a multi-pronged package of Industry promotion,
raising the efficiency of the power sector, increasing energy efficiency and PLF,
and reducing transmission and distribution losses. Involving entrepreneurs
wanting to start Industries in Mizoram in the financing of the furnace oil
plant, in exchange for concessions from the Government, is one option.
