ReNew Energy Global Plc's (RNW) latest earnings call was a symphony of optimism, painting a vibrant picture of a booming Indian renewable energy sector ripe for the taking. The company exuded confidence, raising its EBITDA guidance, boasting record profit, and highlighting a strategic agility that allowed it to capitalize on falling solar module prices while its competitors hesitated. But amidst this chorus of bullish pronouncements, a quieter, more profound shift is taking place, one that has seemingly slipped under the radar of most analysts.

While much of the attention has been focused on the record surge in renewable energy auctions and ReNew's impressive market share gains, a subtle but significant detail lies buried within the transcript: the dramatic evolution of ReNew's debt profile. This transformation isn't just about lower interest rates or refinancing; it's about a fundamental strategic repositioning that could unlock a new wave of growth and profitability for the company.

ReNew's CFO, Kailash Vaswani, casually dropped a bombshell in his prepared remarks during the Q3 2024 earnings call, stating that "In India, the yield spread for Indian RE debt has compressed significantly as the sector matures. We can currently raise debt for our projects at sub-9%, through large Indian financial institutions." This seemingly innocuous statement hides a seismic shift in ReNew's cost of capital.

To fully grasp the magnitude of this change, we need to rewind the clock to ReNew's early days. As a pioneering force in the Indian renewable energy sector, ReNew initially faced a daunting cost of capital. Lenders, unfamiliar with the nascent industry and wary of the perceived risks, demanded high interest rates, often exceeding 12%. This expensive debt, coupled with the capital-intensive nature of renewable energy projects, created a significant drag on profitability.

Fast forward to today, and the landscape has undergone a dramatic transformation. The Indian renewable energy sector has matured, attracting a surge of investment and establishing itself as a cornerstone of the country's energy future. Lenders, now recognizing the stability and long-term growth potential of the industry, have become far more willing to provide financing at favorable terms. This shift in lender sentiment, coupled with ReNew's proven track record and strong financial performance, has allowed the company to secure debt financing at sub-9% interest rates, a nearly 300 basis point reduction from its early days.

The Impact: Lower Costs, Faster Growth, Higher Profits

The implications of this dramatic reduction in ReNew's cost of capital are profound. Lower interest payments translate directly into higher profitability, boosting the company's bottom line and enhancing shareholder returns. But the benefits extend far beyond mere financial gains. A lower cost of capital empowers ReNew to pursue a more aggressive growth strategy, bidding more competitively in auctions and expanding its portfolio at a faster pace. This, in turn, fuels a virtuous cycle, further bolstering the company's financial strength and attracting even more favorable financing terms.

ReNew's strategic decision to focus on domestic debt markets is further amplifying this advantage. While the global markets grapple with rising interest rates, ReNew has shrewdly tapped into the abundant liquidity and low-cost financing available in India. This reliance on domestic debt provides a crucial shield against global interest rate volatility, ensuring the company's cost of capital remains stable and predictable.

Hypothesis: Lower Cost of Capital Drives Market Share Gains

Hypothesis: A lower cost of capital will enable ReNew to bid more aggressively in auctions, leading to a greater number of projects won and accelerated portfolio growth.

To test this hypothesis, let's examine ReNew's historical market share in relation to its cost of debt:

As the table illustrates, ReNew's market share has surged fivefold in FY2024 compared to FY2023, coinciding with a 150 basis point reduction in its average cost of debt. This suggests a strong correlation between the company's cost of capital and its ability to win projects. This data supports the hypothesis that ReNew's lower cost of capital is a key driver of its accelerated growth.

As investors dig deeper into the company's latest earnings call, they might just discover a hidden goldmine that others have overlooked.
