Solar Energy Infrastructure

Published on 25 Feb 2025

Solar Energy Infrastructure in India

• Installed Capacity: India’s solar power capacity surpassed 175 GW by mid-2024, making it one of the largest solar energy markets globally. The country aims to achieve 280 GW by 2030.

• Major Solar Parks:

• Bhadla Solar Park: Located in Rajasthan, it is the world’s largest solar park with a capacity of 2.5 GW.

• Pavagada Solar Park: In Karnataka, this park has a capacity of 2 GW and is among the largest in the world.

• Government Initiatives and Policies:

• National Solar Mission: Launched in 2010, it targets 100 GW of solar power by 2022, later revised to 280 GW by 2030.

• Production Linked Incentive (PLI) Scheme: Introduced to boost domestic manufacturing of solar modules, aiming to enhance self-reliance and reduce import dependency.

• Solar Rooftop Projects: India’s rooftop solar installations have exceeded 10 GW, supported by incentives and subsidies under the Grid-Connected Rooftop Solar Scheme, promoting decentralized power generation.

• Investment and Financing: The solar sector has attracted over $30 billion in investment, driven by both domestic and international investors. The Solar Energy Corporation of India (SECI) plays a pivotal role in facilitating these investments.

• Technological Advancements: Adoption of cutting-edge technologies such as bifacial panels and advanced inverters has increased efficiency and reduced costs. Innovations are also being driven by research in solar storage and hybrid systems.

• Job Creation: The solar sector has created over 700,000 jobs, including in manufacturing, installation, and maintenance, contributing significantly to employment and skill development.

• Export Potential: India is becoming a key player in the global solar supply chain, exporting solar panels and components. The country’s focus on boosting domestic manufacturing is aimed at capturing a larger share of the global market.

• Integration with Grids: Solar power integration into the national grid is being enhanced through the development of smart grids and energy storage solutions, ensuring stable and reliable power supply.

• Environmental Impact: Solar energy helps avoid around 120 million tonnes of CO2 emissions annually, contributing to India’s climate goals and improving air quality.

Challenges faced by Solar energy infrastructure in India

• High Initial Costs: Setting up solar power plants requires substantial investment, with costs around ₹40-₹50 lakh per MW, making it a significant barrier for new projects.

• Land Acquisition Issues: Large solar farms, such as the 2.5 GW Bhadla Solar Park, require approximately 14,000 hectares of land, which can be difficult to acquire in densely populated or ecologically sensitive areas.

• Intermittency and Storage: Solar power output fluctuates with weather and time of day. Current battery storage solutions, essential for addressing intermittency, have costs of ₹4,000-₹5,000 per kWh, impacting widespread adoption.

• Grid Integration: Integrating solar energy into the grid requires upgrades. For example, the integration of 1 GW of solar capacity into the grid can demand investments of over ₹1,000 crore for infrastructure enhancements.

• Policy and Regulatory Hurdles: Solar projects face delays in approvals and clearances. For instance, projects can experience up to 6-12 months of delays due to complex environmental and land use regulations.

• Technological Challenges: Current solar panels have an average efficiency of around 15-18%, meaning a significant portion of sunlight is not converted into electricity, affecting overall performance.

• Financing Issues: Solar projects often struggle with financing due to perceived risks. Approximately 30% of proposed projects face challenges in securing required funds due to high perceived financial risks.

• Maintenance and Durability: Solar panels require maintenance and have a typical lifespan of 25-30 years. Maintenance costs can amount to about 1-2% of the initial investment annually, impacting long-term profitability.

One Sun, One World, One Grid

The One Sun, One World, One Grid (OSOWOG) initiative is a global effort aimed at creating a unified, interconnected solar power grid across multiple countries.

• Objective:  OSOWOG aims to create a unified solar power grid, enabling solar energy exchange between regions. It targets connecting over 100 GW of solar capacity across participating countries by 2030.

• Geographic Scope: Initially focuses on South Asia, Southeast Asia, the Middle East, and Africa, with India leading the initiative. The goal is to connect grids in over 20 countries within these regions.

• Economic Benefit: The interconnected grid can lower solar power costs by up to 20% through shared resources and economies of scale, optimizing energy use across borders.

• Energy Security: By linking multiple countries, OSOWOG reduces reliance on any single nation's energy infrastructure, enhancing overall energy security and stability.

• Environmental Impact: The initiative supports global climate goals by promoting solar energy, which can reduce CO2 emissions by approximately 150 million tonnes annually.

• Technical Integration: The grid will utilize advanced technologies for efficient energy transmission, requiring an estimated $50 billion in infrastructure investments for seamless integration.

• International Partnerships: India is a major proponent, working with countries and organizations like the International Solar Alliance (ISA) to advance the initiative. Collaboration is key to the project's success.

• Future Expansion: OSOWOG envisions expanding beyond the initial regions to a global network, aiming to connect over 500 GW of solar capacity by 2040.
