NHPC Limited disclosed a revision in its Environmental, Social and Governance (ESG) score by S&P Global. The rating agency updated the score to 57 as on August 28, 2026, down from the previous score of 61 awarded in February 2026.
The downgrade stems from the 'Media and Stakeholder Analysis' of the Teesta VI Hydroelectric Project (HEP) incident that occurred on July 20, 2026. NHPC informed stock exchanges about the change in compliance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.
Score Breakdown

| Governance (G) | Reduced |
| Environment (E) | No change |
The Environmental pillar score remained unchanged despite the overall drop.
Company Response
NHPC has raised its concerns with S&P Global regarding the deduction. The company has requested appropriate justification for the reduction in its ESG score. This disclosure follows an earlier communication dated February 14, 2026.
