Business case

Building foundations for Lifelong energy security

In a decisive step towards building a future-ready and resilient solar ecosystem, we have committed ₹6,500 crore to enter the upstream Solar PV ingot and wafer manufacturing segment.

This marks more than a capacity expansion; it is a strategic move ensuring stronger and more resilient supply chains and long-term value creation. By integrating backward into a traditionally import-dependent segment, we strengthen supply chain security, reduce external risks, and enhance operational efficiency. The development of 10 GW (in two phases of 5 GW each) capacity is expected to bring scalable and disciplined growth.

The initiative offers multiple strategic advantages, including improved margins through vertical integration and secure raw material availability for downstream operations. Entry into an emerging, capacity-constrained domestic market also provides a strong first-mover advantage, backed by robust demand visibility and an expected payback of around five years.

Beyond business benefits, the investment supports India's vision of energy security and manufacturing self-reliance by building indigenous ingot and wafer manufacturing capabilities. It reduces import dependence, strengthens the domestic solar value chain, and accelerates the transition towards clean energy.

Aligned with evolving policy frameworks and government incentives, the initiative reflects our commitment to driving business growth while supporting India's ambition to become a global solar manufacturing hub.

The project is structured as a joint venture, with DGPC holding the majority stake and we participating as the private partner. Designed as a run-of-the-river scheme, it comprises six generating units of 187.5 MW each. This project represents one of the largest private-public hydroelectric initiatives in Bhutan and reinforces our strategic focus on clean energy and regional cooperation.

A significant portion of the power generated is earmarked for export to India, contributing to long-term energy security and optimised capacity utilisation. The Dorjilung project benefits from robust financial structuring and international support. Upon commissioning, it will enhance our hydropower portfolio and deliver sustainable value to stakeholders through stable long-term returns.

Leveraging our strategic presence in the Western Ghats to enable round-the-clock (RTC) green energy solutions

As India accelerates its clean energy transition, the need for Round-the-Clock (RTC) Renewable Power is becoming increasingly important to ensure both energy security and decarbonisation. While solar and wind capacities continue to expand rapidly, their intermittent nature creates challenges for grid stability and reliable power supply. Addressing this challenge requires large-scale energy storage solutions capable of converting variable renewable energy into firm, dispatchable power.

Our long-standing presence in the Western Ghats provides us with a strategic advantage in advancing Pumped Storage Projects (PSPs), leveraging the region's favourable hydro-geographical characteristics. Building on this advantage, we are progressing large-scale PSP developments in Maharashtra with an estimated investment of approximately ₹13,000 crore. This includes two projects with a combined planned capacity of 2,800 MW: the 1,800 MW Shirwata PSP and the 1,000 MW Bhivpuri PSP.

Enabling reliable renewable energy integration

As renewable energy penetration increases, ensuring grid flexibility and reliability becomes critical. PSPs play an important role in balancing renewable generation by storing surplus energy during periods of high generation and supplying power during peak demand. These projects provide large-scale, long-duration energy storage, support grid balancing, improve renewable integration, and enhance system reliability through rapid response capabilities.

By utilising the natural elevation and reservoir potential of the Western Ghats, our PSPs are designed to operate as efficient, long-life energy storage assets that support the transition towards a cleaner and more resilient energy system.

We are strategically integrating PSPs with our solar and wind portfolio to deliver firm and reliable green power. This integrated renewable energy-storage model enables us to store surplus renewable energy during off-peak periods and optimise dispatch during peak demand hours, while reducing renewable curtailment and improving asset utilisation. Supported by advanced scheduling and energy management systems, the model helps convert variable renewable generation into stable, grid-quality power supply.

Progress on key projects

We have made significant progress on both flagship PSPs.

Creating long-term value

RTC Renewable Power is becoming increasingly important for commercial and industrial customers seeking reliable and sustainable energy solutions. Our integrated RE-PSP model supports customers through reliable clean power supply, reduced exposure to peak power costs and tariff volatility, and accelerated progress towards sustainability and net-zero goals.

For utilities and grid operators, PSP-integrated renewable solutions enhance grid resilience by providing peak load and balancing support, supporting frequency regulation and reserve management, and enabling higher renewable energy integration at the system level.

Through our PSP-led renewable energy strategy, we are strengthening our portfolio of firm and dispatchable green energy while supporting India's broader clean energy ambitions. Beyond enabling decarbonisation and energy security, these projects are also expected to contribute to regional economic development, employment generation, and long-term infrastructure creation.

By leveraging our strategic footprint in the Western Ghats, we are enabling scalable RTC green power solutions that balance reliability, affordability, and sustainability, reinforcing our commitment to building a resilient and low-carbon energy future.
