Generation Based Incentive: Powering India Renewable Revolution in 2025

Generation based incentive schemes have transformed India’s renewable energy landscape, rewarding producers for each unit of clean electricity generated and fed into the grid.

Launched by the Ministry of New and Renewable Energy (MNRE), these incentives aim to boost power generation from solar power and wind energy, with the GBI scheme providing up to Rs 0.50 per kWh for eligible projects.

As of September 2025, India’s renewable capacity has surged to over 226 GW, with 30 GW added this year alone, driven by such policies.

The Indian Renewable Energy Development Agency (IREDA) plays a pivotal role in disbursing these funds, ensuring developers can avail financial support while accelerating the shift to sustainable energy generation.

What Is a Generation Based Incentive Scheme?

A generation based incentive is a financial mechanism under the GBI scheme that compensates wind power producers and solar power developers for the actual electricity generated.

Unlike fixed tariffs, this incentive ties rewards directly to output, measured in kWh, encouraging efficient operations and higher capacity utilization.

In 2025, with India’s renewable targets pushing for 500 GW by 2030, the scheme remains a cornerstone, supporting grid interactive projects that supply clean power to utilities.

The GBI focuses on new and renewable energy sources, particularly wind and solar, where incentives are disbursed over 10 years at rates like Rs 0.50 per kWh for wind power projects.

This structure has led to a CAGR of 11.26% in wind energy capacity from 2025 to 2030, projecting growth from 48.16 GW to 89.49 GW. For solar PV plants, similar benefits apply, making the scheme vital for reducing reliance on fossil fuels.

How Does the GBI Scheme Operate?

The GBI scheme operates through quarterly claims processed by IREDA, verifying power generated and ensuring compliance with eligibility criteria like grid connectivity.

Developers submit meter readings and audited data, receiving payments that offset high cost installations. In 2025, enhancements include streamlined digital portals for faster disbursement, reducing delays from months to weeks.

For eligible projects, the incentive caps at Rs 1 crore per MW, with annual disbursements limited to one-fourth of the total over the first four years.

This phased approach motivates sustained performance, as seen in solar power generation where GBI claims have supported over 123 GW cumulative solar capacity.

Transitioning to this model, MNRE integrates it with other tools like accelerated depreciation, amplifying returns for project developers.

Eligibility Criteria for Generation Based Incentives

To qualify for generation based incentive, projects must meet strict eligibility standards set by MNRE, including a minimum capacity of 5 MW for wind power and grid interactive setup.

Solar power projects need approved technology and third-party certification, excluding captive or merchant sales initially. In 2025, updates emphasize compliance with Approved List of Models and Manufacturers (ALMM) for solar PV plants.

Key criterion include:

• Installation post-commissioning date, with projects commissioned before March 2017 for legacy GBI.
• No overlap with tariff benefits from SERC or central subsidies.
• Maximum limit on total incentive per MW, ensuring equitable distribution.

These rules ensure only viable renewable energy initiatives benefit, fostering a robust ecosystem for wind and solar energy.
