Where are we heading? We
are only talking about and expecting the reduction of the number of hours of
power cut per day. In fact this is not the solution for the present power
crisis. It is already in the eleventh hour, however not too late to act. It is also
time to think about a long term, permanent solution.
The recent improvements
due to the power supply; about 70MW from the mid-Marshyangdi Hydroelectric
Project, and 15MW because the government stopped uninterrupted power supply for
VIP, and also due to the increase in temperature, which will increase the water
level that increases the efficiency of existing power plants like Kulekhani and
others.
More
crises are inevitable if the NEA and the government do not take proper actions,
right now. That should include the construction of short; medium and long range
hydropower generation plants as well as adequate transmission lines. All of the
existing 132kV to 220 kV (where required) are highly recommended for an upgrade
and the existing ring (transmission line in
Power Generation and
the Potential Market:
There is possible
power generation of the 457-MW Upper -Tamakoshi, 30-MW Chamelia and 60-MW
Kulekhani III among others, which according to the NEA is underway. If it takes
place right away usually it will take 5-7 yrs. That means there is some hope to
meet the growing annual load demand of 10.2%. But the NEA or the government
must continue planning for other short, medium and long range terms of
hydropower generation. If we (

are lots of reports and information, which are not only ignored but neglected,
by the Nepal Electricity Authority (NEA) and the Government of Nepal that have

So
it is not only the question of the power cut crisis which we are facing but the
real issue must be the electrification of the entire nation. We need to look at
other strategies for adequate planning and migrating policies to bring the
spread of villagers together as required for building a new

main goal of the NEA and the government should be focused on the hydropower

given to the public sector and to improving the Hydropower Development Policy
of 1992. Bureaucracy and corruption not only bring power cuts but it dooms the
long-term future development of
It is time to start new culture of
transparency, dynamic policy and smart negotiations within the country and with

Rich
Hydro-Power Potential (White Gold) Scenario; Serious Consumption of Wood Fuel:
However, the present situation is that
We should not only be
talking about the 40% of people with access to electricity but all the people.
We need to think and act to make electrification of the whole country possible
by using hydropower as a backbone for the development of the nation. This is
possible and we need to point the nation in that direction. We must leave
behind 60% of the people who still do not have access to the electrical power
grid. Power cuts have serious consequences as not only the 40% of people with
electricity suffer but industries and the nation as a whole are in trouble. We
can not take steps backward in this competitive world but we definitely need to
move forward and we must not forget the backbone of
Tentative Cost of
Projects Based on Examples; Can we afford them and what shall we do?
The total power
generation of the 600 MW Sun-Kosi 1, which will be about $2500 per 1kW
generation cost. So we know it will cost about 1.5 billion dollars; about the
size of 600MW and about 400MW like Tamar about 1 billion dollars. Turnkey
project completion will be about 7 yrs including feasibility studies to the
completion.
The NEA is also
planning the generations that include the 457-MW Upper -Tamakoshi, 30-MW
Chamelia and 60-MW Kulekhani III among others per recent comment.
Here we are talking
approximately about 1.14 billion 75 million dollars for Chamelia.
We need about 150 million dollars for Kulekhani Projects. So funding is crucial
and the NEA and the Nepalese government must work intensively on it.
If it can be generated
within 5-7 yrs, it can meet the demand and may give min. surplus of about 47 MW
during the summertime however in the wintertime we need to have face with the
power cut as we still may not be able to meet peak demand load.
As we have the
potential hydropower for development there is always a potential consumer, if
the country can achieve political stability this will help move towards the industrialization
of the country and then the whole scenario will change and there will be sudden
increase in peak load demand that will be more than 10.2% annually. So we have
to be prepared for such possible scenario also.
Recommendations for
Planning and Controlling the Consumption of Energy:
Load Forecasting:
Forecasting of power
requirements found a minimum of about a 6% error. I wrote my thesis, “Power
System Planning” in 1986 using
Leakage Control:
There are a few things we have to look at seriously; for
example leakage of electricity in
Cluster analysis may be great tool to use for reducing
leakage beside technical and other options.
An Energy Compliance Code:
An Energy Compliance Code needs to be introduced in densely
populated, developed areas that may apply both Industrial/Commercial and
Residential Sectors that will have some control of energy consumptions as well
as help to provide only optimum energy for the consumer. This new compliance
will provide not only an energy saving policy but it will also play in major
role in fighting back the energy crisis.
Here is an example of the Title 24 compliance code from the
state of
For a commercial building in an office you can use only 1.2
watt/square foot (sf), for corridor/toilet only 0.6
watt/sf, restaurant 1.6 watt/sf,
lobby 1.1 watt/sf, retail store 1.6 watt/sf, this is just one simple example. Also there is a new
rebate policy if someone can generate solar energy and if clients have excess
energy this energy can be sent to the utility grid providing rebate policy. NEA
can initiate such projects and encourage the NEA customers.
Electrical retrofit will be another issue; implementing a
policy to replace all the existing lighting and encouraging clients of the NEA
to begin using energy efficient light fixtures such as energy efficient
fluorescent compact fixtures, bringing mandatory rules for using
time-clock/Photo-Cell/Occupancy sensor for exterior and interior lighting
control for commercial buildings, industrial facilities and large residential
buildings, school, colleges, universities.
How to Provide Power to Remote Places?
There are possibilities to begin using solar power that will
definitely improve the health of villagers and give them an opportunity to have
at least some light. However there is
still a tough question, shall we go for solar tuki (as
recommended by renewable energy groups) or should the country adopt a new
policy re-grouping migration policy that not only looks at the adequate supply
of lighting but the entire socio-economic structure based on possible
agriculture and the development of light industries exploiting hydropower.
Regarding wind-power there are possibilities in
(as a pilot study) is evaluated for less than 1 MW wind power.
But it is also felt that, only in the
Kagbeni area, there is feasibility of more than 25 MW of wind power. In
the past we have installed two small wind-power stations which were complete
failures due to technical unreliability and such things cannot be repeated.
So
although hydropower/micro-hydropower plants come first in possible remote areas
one should look at renewable energy and the cost and then compare them to hydropower
generation and begin work in the right direction. We should not rule out that we must have
several approaches for building a new
Recommendations to Resolve
the Current Power Crisis:
Many experts on
1. There is an existing power exchange agreement between
2. Alternatives can be a temporary diesel plant of about
100MW just to match the current peak demand. We should minimize the usage of diesel
plants which are expensive and not environmentally friendly.
3. Identify immediately short, medium and long range
potential hydropower plants that can be started immediately; such as short
range projects between 100MW-500MW and complete within 5-7 yrs. The NEA and the
government must work with neighboring countries like
4. Attract private
parties both domestic and foreign. The private sector needs to be an important
stakeholder in the entire process as well as collaborating with both domestic
and foreign parties.
5. An independent regulator is needed to oversee generation,
transmission and distribution of electricity thorough the country. This
encompasses greater importance when power is to be traded across international
borders.
6. Sound regulatory and policy reforms are required to
attract both national and foreign investors. Sound reforms allow for purchasing
power and the selling and sharing of technology and services in
7. Hydropower development in
8. Studies and plans for alternative energies such as wind
and solar need to be conducted. But the MAJOR goal needs to be hydropower
development.
