How Does Reliance Power Operate its Power Plants?

Reliance Power's operational framework is built on a diverse portfolio of power generation assets. Its core strategy involves using stable, high-performing thermal plants to generate consistent cash flow while aggressively expanding its footprint in the high-growth renewable energy sector.

Core Thermal Assets: The Foundation of Revenue

These coal-based plants are the company's primary workhorses.

• Sasan Ultra Mega Power Project (UMPP): With a massive capacity of 3,960 MW, this is the company's flagship asset in Madhya Pradesh. In FY 2024-25, it achieved an exceptional Plant Load Factor (PLF) of 90.6%, far exceeding the national average of around 69%. This high efficiency translates directly into higher power generation (31,425 million units in FY25). A key advantage is its integration with captive coal mines, which protects it from fuel price fluctuations.
• Rosa Coal-based Power Project: This 1,200 MW plant in Uttar Pradesh is another consistent performer, generating 7,403 million units in FY25. Its revenue is secured by a "cost-plus" Power Purchase Agreement (PPA), which guarantees stable returns by covering costs and adding a fixed profit margin.

Strategic Pivot: The Shift to a Greener Future

The company is actively pursuing a "Resurgent Reliance" theme, focused on adapting to India's energy transition.

• Asset Monetisation: Management is selling equipment from its non-operational gas-based plant in Samalkot. One module has been exported for a joint-venture project in Bangladesh, with the proceeds used to reduce company debt.
• Expansion into Renewables and Battery Storage: This is the most crucial part of its future strategy. A subsidiary has signed a landmark agreement with the Solar Energy Corporation of India (SECI) to develop a 930 MW solar project combined with a 465 MW/1,860 MWh Battery Energy Storage System (BESS). This project positions Reliance Power as a leader in India's burgeoning energy storage market.
• Existing Renewable Operations: The company already operates a 40 MW solar photovoltaic plant and a 100 MW concentrated solar power (CSP) project in Jaisalmer, Rajasthan, both secured with long-term PPAs.

What Are Reliance Power's Main Sources of Revenue?

Understanding how revenue flows into the company is important. Here's the revenue break for the financial year 2025 (FY25).

1. Sale of Power via Long-Term Agreements (PPAs): This is the primary source of income. Reliance Power sells the electricity it generates to state power distribution companies (DISCOMs) through long-term Power Purchase Agreements (PPAs). These contracts typically last for 25 years and lock in the price (tariff) at which electricity is sold, ensuring a stable and predictable revenue stream. For example, the Sasan plant supplies power to 14 DISCOMs across seven states under a competitively bid tariff.
2. Income on Finance Leases: For certain projects, like the Rosa Power Plant, the PPA is structured so that a portion of the fixed charges received is accounted for as "Income on assets given on finance lease." This is an accounting treatment but forms a part of the structured revenue flow from the PPA.
3. Other Income: This category includes supplementary revenue sources such as interest from customers on delayed payments

• 350 MW Solar + 700 MWh BESS Project: Secured by its subsidiary, Reliance NU Energies, through a competitive auction.

International Power Generation Projects:

• 718 MW Gas Power Plant in Bangladesh: An ongoing project near Dhaka in partnership with JERA Power International of Japan.
• 500 MW Solar Joint Venture in Bhutan: A 50:50 joint venture with the investment arm of the Bhutan government to develop the country's largest solar project.

Frequently Asked Questions (FAQs)

Q1: What is Reliance Power's main business?
Reliance Power's primary business is power generation. It operates large-scale thermal (coal-based) power plants that generate stable revenue and is now expanding aggressively into renewable energy, specifically solar power and battery energy storage systems (BESS).

Q2: How does Reliance Power guarantee its income?
The company guarantees its income primarily through long-term Power Purchase Agreements (PPAs), which are typically 25-year contracts with state and central government entities. These agreements lock in the price of electricity, providing highly predictable and stable, long-term revenue streams.

Q3: Is Reliance Power shifting away from coal?
Yes, Reliance Power is making a significant strategic pivot towards renewable energy. While its coal plants currently form the bedrock of its revenue, its future growth strategy is heavily focused on developing large-scale solar power projects and battery storage systems, both in India and internationally.

Q4: What is a Battery Energy Storage System (BESS) and why is it important for Reliance Power?
A Battery Energy Storage System (BESS) stores electrical energy for later use. It is crucial for renewable energy sources like solar, which are intermittent (only generating power when the sun shines). By investing in BESS, Reliance Power can provide reliable, round-the-clock power from its solar projects, making it a more competitive and future-ready energy provider.

Q5: What do Reliance Power's international projects involve?
Reliance Power is expanding its presence beyond India. Its key international projects include a 718 MW gas-fired power plant in Bangladesh, developed in partnership with Japan's JERA, and a major 500 MW solar project in Bhutan, developed as a joint venture with the Bhutanese government's investment arm.
