Sustainability efforts

India is the third-largest energy consumer in the world after USA and China with the fifth largest installed thermal power capacity in the world.

However, it also ranks third in emissions of greenhouse gases.

Therefore it is very important for the companies in this sector to reduce their carbon footprint.

Both Adani Green and Tata Power are increasing their investments in renewable energy space to produce green energy.

Adani Green has been providing green energy for several years now and is investing to increase its renewable energy mix. The company is also focusing on reducing its consumption of resources and efficiently managing its waste.

On the other hand, Tata Power is phasing out its existing thermal capacities and has stopped investing in new ones. It is concentrating on using resources responsibly, foraying into renewable energy at a faster pace.

The company has also been making its sustainable offerings in the consumer business more affordable and accessible to encourage its consumers to adopt a sustainable lifestyle.

Impact of Covid-19

The pandemic had disrupted the demand for power in the country in the first half of the financial year 2021. There were supply chain bottlenecks and significant changes in the energy consumption patterns.

As a result, the revenue and profitability of both companies were impacted at the time. However, the demand picked up once the lockdown restrictions were eased, and the power consumption in India was the highest at 190 gigawatts (GW).

Going forward, the demand for power will continue to rise as India's population grows. Government initiatives such as 'Power for all' will also increase energy consumption in the country.

Future prospects look bright

India's per capita energy consumption is less than half the global average. With rising population and government initiatives to make India a manufacturing hub, the energy usage in the country is expected to grow.

The government is encouraging energy companies to produce cleaner power by giving high incentives and subsidies. This has given a much-needed boost to the renewable energy space.

Tata Power is continuing to expand across all its businesses. It is aggressively investing to increase its renewable energy portfolio.

It is also collaborating with automobile companies and original equipment manufacturers (OEMs) to roll out EV charging infrastructure in the country.

On the other hand, Adani Green's partnership with Total, a French energy company, is expected to increase its in footprint in the clean energy space.

The company has also secured many orders indicating a solid revenue growth in the medium term.

Which is better?

Though Tata Power's revenues are almost 20 times Adani Green's, it has a lower revenue and volume growth.

However, Tata Power is leading in terms of net margin. It also pays higher dividends to its shareholders, has a lower debt-to-equity ratio, and gives a higher return to its shareholders.

With its presence across the energy value chain, Tata Power is looking to capitalize on the entire growth in the power sector.

Adani Green, on the other hand, has a higher share of renewables in its power portfolio. It also has a high operating margin, indicating its operational efficiency.

In terms of valuations, Tata Power is leading. Its shares are less expensive than Adani Green.

While both the companies are dominant players in the energy space, before taking a leap and investing in them, go through the fundamentals and valuations of both the companies. It will help in your decision-making process.
