[2025] 8 S.C.R. 345 : 2025 INSC 922
Gujarat Urja Vikas Nigam Limited 
v. 
Green Infra Corporate Wind Private Limited  
and Others Etc.
(Civil Appeal No(s). 14098-14101 of 2015)
04 August 2025
[Sanjay Kumar* and Satish Chandra Sharma, JJ.]
Issue for Consideration
Whether the four respondent companies were entitled to 
approach the Gujarat Electricity Regulatory Commission (GERC) 
for determination of the tariff for procurement of power by  
Appellant-GUVNL from their wind energy projects.
Headnotes†
Electricity Act, 2003 – ss.61, 62, 64, 86 – Income Tax Act, 1961 – 
s.32 – Power Purchase Agreements (PPAs) entered into between 
GUVNL and the respondent companies containing a clause w.r.t 
the tariff applicable for purchase of power from the respondent 
companies’ wind energy projects – Respondent companies 
approached the GERC seeking project-wise determination of 
tariff, claiming that they had not availed accelerated depreciation 
under the Income Tax Act, 1961 – Claim contested by GUVNL, 
arguing that they had willingly entered into PPAs and were 
bound to the tariff rate of ₹3.56 per kWh, and therefore, could 
not seek determination of tariff on a case-to-case basis – GERC 
decided the issue in favour of respondent companies – Order 
confirmed by the APTEL – Correctness:
Held: GUVNL, an instrumentality of the State is bound to promote 
and give effect to the Government’s policy of encouraging generation 
of power from renewable energy sources – When the Government 
promulgated a policy in that regard, offering various incentives to 
wind energy projects, GUVNL cannot act contrary thereto by fixing a 
tariff for purchase of power from such wind energy projects contrary 
to the mandate of Order dated 30.01.2010 issued by GERC as per 
which the tariff of ₹3.56 per kWh was applicable only to those wind 
energy projects that availed the benefit of accelerated depreciation –

Supreme Court Reports
It is not disputed that the four respondent companies did not avail 
such benefit – Thus, the question of applying to them the tariff that 
was only meant for wind energy projects that did avail accelerated 
depreciation would not arise – GUVNL cannot be guided only by 
its own commercial interests, like a private business entity and it’s 
conduct, as a State instrumentality, must be of the standard of a 
model citizen – It cannot contend that the respondent companies are 
estopped from seeking determination of tariff by the GERC as they 
had willingly signed PPAs with it at the tariff fixed for wind energy 
projects availing accelerated depreciation – As GUVNL failed to 
obtain commitments from the respondent companies that they would 
only avail accelerated depreciation at the time they had to choose 
that option, GUVNL has no indefeasible right to bind them to a tariff 
which was applicable only to such wind energy projects that availed 
accelerated depreciation – Orders passed by the GERC and the 
APTEL not interfered with – Income Tax Rules, 1962. [Paras 24, 25]
