With
new guidelines effective from this year, there is an option of 30% dry energy
for RoR projects. In this option, hydropower projects will receive NRs. 8.40
per kWh for six months (Mangsir 16 – Jestha 15) and NRs. 4.80 for the remaining
6 months (Jestha-16 to Mangsir 15). However, the total dry energy should be more
than 30% of the total energy supplied. Any projects suppling dry energy below
30% will be penalized. The formula for such compensation to NEA will be the
following
Compensation
Amount = (Total energy supplied in a year – Total annual estimated energy based
on 30% dry season energy) x PPA rate of the wet season applicable for the
fiscal year.
Apart
from “Total annual estimated energy based on 30% dry season energy”, other
terms are very clear. So, what is Total annual estimated energy based on 30%
dry season energy?
According
to NEA’s decision
Suppose:
Annual contract energy (X) = 100 GWh
Minimum
dry energy to be supplied = 0.3X
Suppose:
dry energy supplied in a year (Y) = 29 GWh
Total
annual estimated energy based on 30% dry season energy = Y/0.3=96.67
Before
doing an assessment to find out its practical implications, it should be noted
that many hydropower projects in Nepal are struggling to supply contracted
energy. There is a huge variation in Contract Energy and the Actual Energy
supplied by hydropower project (Disappointing PLF).
Now let’s do an assessment. Before that, below are some practical assumptions

*To
meet the criteria of 30% dry energy, I guess projects have to be designed above
of Q40. So, I think 65% PLF is quite reasonable.
Based
on above PLF, the energy generation will be the following

Above
calculation is based on the first year of generation.
There
will be sufficient discharge in wet season which is a typical nature of this
country. However, projects are likely to suffer during wet season. The above
figures show that the compensation clause on 30% dry energy option should not
be taken lightly by the stakeholders (developers, investors and banks)
