The Appellate Tribunal for Electricity rejected an appeal by a rooftop solar consumer seeking enforcement of a tariff of ₹9.56 (~$0.11)/kWh for a rooftop solar system, as per an initial Power Purchase Agreement (PPA) signed on December 10, 2015. Instead, the Tribunal upheld a revised tariff of ₹5.67 (~$0.067)/kWh, as outlined in a supplementary PPA executed on March 21, 2017. The Tribunal said the petitioner had neither challenged the supplementary agreement nor demonstrated that it was signed under protest, rendering the revised terms binding.
