The Energy and Resources Institute (TERI) organized a high-level stakeholder consultation focused on the potential of Concentrated Solar Power with Thermal Energy Storage (CSP-TES) to support the delivery of firm and dispatchable renewable energy in India. The event brought together policymakers, industry leaders, researchers, utilities, and technology experts to discuss the role of long-duration energy storage in strengthening the country’s clean energy transition.
As India continues to expand its renewable energy capacity, ensuring a stable and reliable power supply has become a key priority. During the consultation, participants highlighted the importance of integrating storage technologies that can provide electricity even when solar and wind resources are unavailable. CSP-TES was identified as a promising solution due to its capability to store thermal energy and generate power on demand, helping address the intermittency associated with renewable energy sources.
The discussions explored various aspects of CSP-TES deployment, including technology readiness, project economics, policy support mechanisms, financing requirements, and market opportunities. Experts noted that CSP-TES can complement other energy storage technologies such as battery energy storage systems and pumped hydro storage by offering long-duration storage and enhancing grid flexibility.
Stakeholders also emphasized the potential of CSP-TES to deliver round-the-clock renewable power, improve grid reliability, and support emerging applications such as green hydrogen production and industrial decarbonization. Participants underscored the need for supportive regulatory frameworks, targeted incentives, and pilot projects to accelerate the commercialization of the technology in India.
The consultation further examined ways to improve project bankability and attract investments into the sector. Discussions included procurement models, tariff structures, and policy measures that could help create a favorable ecosystem for large-scale CSP-TES deployment.
TERI highlighted that a diversified portfolio of energy storage solutions will be critical for achieving India’s clean energy ambitions while maintaining grid stability. The institute stressed the importance of collaboration among government agencies, financial institutions, developers, and technology providers to unlock the full potential of dispatchable renewable energy.
The outcomes of the consultation are expected to contribute to ongoing policy discussions and support efforts to develop a resilient, low-carbon power system capable of meeting India’s growing energy needs while advancing its long-term sustainability goals.
