Public infrastructure finance company REC has floated an expression of interest (EoI) for participation in an Indian Energy Stack (IES) pilot focused on an interstate peer-to-peer (P2P) energy trading use case.

Participants can demonstrate their platform’s ability to deliver secure, interoperable integrations and conformance to the Application Programming Interface (API) within a scalable, multi-stakeholder ecosystem.

Participants can also contribute to a flagship IES use case.

Bids must be submitted by January 16, 2026.

IES is a digital public infrastructure for identifying and connecting stakeholders to assets. REC said this infrastructure will facilitate open data exchange in the power system through uniform specifications and standards, and unlock transparent, inclusive, reliable, affordable, and efficient energy access.

The energy trading pilot will deploy IES specifications for the interstate P2P trading workflow. This process will involve testing end-to-end interoperability, including consent-based data exchange, standard payloads, auditability, and integration with utility and market-relevant systems.

The scope of work entails building or adapting a P2P trading platform. It also involves integration of the platform with an IES-compliant interstate P2P network.

The trading platform will be used by consumers and prosumers to trade as per IES specifications.

The platform must integrate with utility systems, such as master data management, enterprise resource planning, risk management, and billing, via open APIs, webhooks, or secure file interfaces.

The onboarding date is January 17, 2026. The final delivery date of the trading platform is February 5, 2026.

Bidders must be technical service providers with experience in power markets, digital platforms, energy systems, and fintech firms. It must also support consent-based data exchange, audibility, and interoperable payloads per the IES specifications.

Last June, the Ministry of Power launched a task force to establish the IES, aiming to address India’s fragmented energy systems and a lack of seamless digital integration. These issues are hurdles to energy transformation, despite the accelerated growth in the country’s renewable energy and electric vehicle sectors.

In 2024, the regulatory commissions of Karnataka and Delhi issued guidelines for P2P buy-sell electricity transactions using blockchain technology.
