Compensation clause for 30% dry energy.



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

PLF*
65%
*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)
