The Proof & Experimental Establishment (PXE), a key laboratory under the Defence Research and Development Organisation (DRDO), has issued an Expression of Interest (EOI) for the development of a 5 MW grid-connected solar power project integrated with a Battery Energy Storage System (BESS) at its Chandipur facility in Balasore district, Odisha.
The proposed project forms part of PXE’s strategy to strengthen energy security for its critical defence testing operations while advancing the adoption of clean and sustainable energy solutions. PXE plays a crucial role in proof and flight testing of armament stores and artillery systems, making reliable and uninterrupted power supply essential for its operations.
The project will involve the installation of a ground-mounted solar photovoltaic (PV) plant along with a battery energy storage system to enhance power reliability, manage intermittency in solar generation, and support grid stability. The integration of energy storage is expected to ensure a consistent power supply, particularly during peak demand periods and grid fluctuations.
The project will be executed under the Renewable Energy Service Company (RESCO) model, wherein a Solar Power Developer (SPD) will be selected to undertake the end-to-end responsibility for the project. This includes design, financing, engineering, procurement, construction, testing, and commissioning of the solar-plus-storage facility. Post commissioning, the developer will also be responsible for operating and maintaining the plant for a period of 25 years.
PXE has earmarked approximately 25 acres of land within its Chandipur campus for the installation of the solar PV and BESS infrastructure. While the entire project cost, including the construction of evacuation infrastructure up to the nearest state substation, will be borne by the selected developer, PXE will provide administrative and facilitation support. The establishment will also assist in enabling the execution of a Power Purchase Agreement (PPA) with the local electricity distribution utility to ensure seamless power offtake.
The EOI is open to Indian companies and consortiums meeting defined technical and financial eligibility criteria. On the technical front, bidders must demonstrate prior experience in developing at least 25 MW of cumulative grid-connected solar capacity, including at least one project of 5 MW or above. Additionally, applicants must have a minimum of six months of operation and maintenance experience for a solar project of similar scale.
Financial eligibility requirements include submission of audited financial statements for the last three financial years and proof of positive net worth, ensuring participation by financially stable and credible developers.
Interested bidders are required to submit detailed proposals, including concept notes, project execution strategies, and supporting technical and financial documentation. The EOI document does not specify submission deadlines, pre-bid meeting schedules, or details related to earnest money deposit and performance bank guarantees, which are expected to be outlined during the subsequent Request for Proposal (RFP) stage following shortlisting.
