Three of India's biggest central state-owned enterprises -- Coal India Limited (CIL), NTPC, and Indian Railways -- can help the country reach its climate goals while seizing a share of the clean energy market and mitigating an estimated 22-28 per cent cash flow gap by 2050 as India gears itself towards net-zero, a new report by the International Institute for Sustainable Development (IISD) said on Tuesday.

The study, India's state-owned Energy Enterprises, 2020-2050: Identifying Evidence-Based Diversification Strategies, uses public sector undertakings (PSUs) in the coal sector to show how energy businesses can identify their future uncertainties while also identifying opportunities in the changing energy system.

"State-owned companies can be part of India's clean energy future while continuing to bring revenues to the government, creating jobs, and supporting local communities," says co-author of the report Balasubramanian Viswanathan, Policy Advisor at IISD.

"Our evidence-based approach shows pathways for how this can be achieved."

The study finds that between 2020 and 2050, under the net-zero-aligned pathway, CIL and Indian Railways could face a Rs 415 billion (28 per cent) and a Rs 2,112 billion (22 per cent) reduction in cash flow, respectively, while NTPC's cash flow could drop by Rs 404 billion (22 per cent) compared with a business-as-usual scenario.

But taking a few concrete measures in the next few years to diversify their businesses can allow these firms -- and other similar PSUs in India -- to alleviate future uncertainty and avoid revenue gaps, argue the authors of the report.

The report favors early diversification.

For instance, the study finds that PSUs must create net-zero roadmaps with interim targets for the firm, which can become a guide for future decisions, and develop in-house estimates on the financial impact of the changing energy landscape.

They can also use their ability to raise capital at favorable rates to identify diversification strategies and become early adopters of clean energy technologies.

To do so, firms should set clean energy targets in proportion to the potential scale and speed of the financial implications, and periodically increase the ambition of these targets, the experts recommend.

Furthermore, building strategic partnerships among PSUs to exchange expertise and invest in research and development can help PSUs build internal capacity in new and emerging clean energy technologies.

Finally, making their ambitions toward achieving a clean energy transition public can send positive market signals that can further strengthen previously mentioned measures.

"As major employers in the conventional energy sector, PSUs are key actors in reaching India's climate and energy targets, and they should involve other relevant stakeholders in the decision-making process," says Viswanathan.

The authors of the report encourage all state-owned energy enterprises to adopt this approach to produce their detailed internal assessments and an evidence-based strategy for transition into a clean energy business. (AA/IANS)
