India’s Peak Power Demand to Hit 459 GW by FY36 as Green Energy Surges
A new report reveals India's peak power demand will surge to 459 GW by FY36, with non-fossil fuel generation expected to reach 48%.

India is bracing for a massive surge in electricity requirements, with peak power demand projected to climb from the current 245 GW to a staggering 459 GW by the 2035-36 fiscal year. This rapid growth in consumption is being met by a significant shift toward cleaner energy, as non-fossil fuel generation is expected to rise from 29 per cent to 48 per cent during the same period.
According to a recent research report by Anand Rathi, the renewable energy sector in India is undergoing a fundamental transformation. The industry is moving away from merely adding basic capacity toward a model focused on providing firm, contracted, and reliable electricity.
A Shift from Low Tariffs to Grid Reliability
The way electricity is bought and sold in India is changing. In the past, the market operated on a "lowest tariff wins" model, where the cheapest bidder secured the contract. However, the report highlights that the industry has transitioned to a "lowest delivered cost wins" philosophy. This means that the focus is no longer just on the cost of generation, but on the ability to deliver power reliably when it is needed most.
The mantra in the industry is shifting from "generation is the product" to "dispatchability is the product." To meet this need, procurement patterns are evolving:
- Hybrid and Round-the-Clock (RTC) models: These are becoming the standard for new projects.
- Firm and Dispatchable Renewable Energy (FDRE): This ensures power is available even when the sun isn't shining or the wind isn't blowing.
- Storage Solutions: Battery and other storage technologies are becoming the essential enablers for grid stability and commercial optimization.
This shift is reflected in tender data. In FY24, hybrid, RTC, and firm renewable energy options accounted for 44 per cent of tenders. By FY26, this figure is expected to jump to 86 per cent.
New Demand Drivers: Data Centres and Industry
While state distribution utilities remain the primary buyers, new players are entering the market. Commercial and industrial (C&I) consumers, merchant traders, and data centres are emerging as significant off-takers of power.
The demand from the technology sector is particularly noteworthy. The renewable power required specifically for data centres is projected to grow from 16.1 GW to 32.4 GW between the years 2026 and 2030. Additionally, conventional commercial and industrial demand is set to expand to 121 GW.
The Premium on Firm Supply
As the need for reliability grows, so does the price for guaranteed power. The report notes that "firm supply commands a premium," with tariffs for assured-peak FDRE being approximately twice as high as those for standard utility solar combined with Battery Energy Storage Systems (BESS).
Challenges in Infrastructure and Execution
Despite the optimistic growth projections, significant hurdles remain in the path of India's energy transition. The report identifies several critical bottlenecks:
- Transmission Gaps: Only about 48 GW of the required 335 GW inter-state renewable transmission system has been completed to meet the 2030 target.
- Contractual Delays: Approximately 45 GW of awarded utility capacity is currently stuck without signed power purchase agreements.
- Policy Changes: The waiver on inter-state transmission system charges is set to gradually decrease from 75 per cent in FY26 to zero by July 2028, which could impact project economics.
As India races toward its green energy goals, the ability to execute large-scale projects and expand grid capacity will be the deciding factor in managing the massive leap in power demand.
