Project-specific tariff shall be determined in the following cases:

  • Small hydro projects (1 MW to 25 MW).
  • For renewable energy projects which have been commissioned before 31 March 2017 without a power purchase agreement, the project’s tariff shall be determined on an annual basis.
  • Solar PV.
  • Wind energy.
  • MSW and RDF based projects with Rankine cycle technology.
  • Hybrid projects approved by MNRE.
  • Any other new renewable energy technologies approved by MNRE.

 

Financial and operational norms specified in the regulations will be ceiling norms.

 

Capital Cost

All capital costs are for FY 2018-19, and the same for subsequent years are determined using indexation formula given in Regulations.
