Reliance Infrastructure, one of India’s top engineering and power sector companies, has secured a major contract from NHPC Limited to construct a 390MW solar power plant combined with a 780MWh BESS, representing a crucial milestone in the country’s clean energy growth. The deal – one of the biggest to date in the public sector for hybrid solar and storage – once again positions Reliance Infra as a preferred technology and execution partner for utility-scale renewables across India.

The greenfield project will be constructed amid NHPC’s drive to expand its renewable energy portfolio and aid grid resiliency as India races toward its national goals for green energy and enhanced electricity reliability. To be located strategically, the plant will provide clean, dispatchable power for daytime and evening loads, enhancing grid stability and reducing curtailment that occasionally impacts standalone solar arrays.

The order’s centrepiece is its pairing of massive solar generation with utility-scale battery storage, enabling the plant to store energy oversupplied during periods of peak sunshine and distribute it after sunset or during demand spikes. The 780 MWh BESS will use cutting-edge lithium-ion or flow battery technology—dependent on final vendor selection—optimised for fast response, cycling and sustained dispatch across multiple hours.

Reliance Infra’s responsibilities span engineering design, procurement of solar modules and energy storage systems, construction, commissioning and long-term maintenance. The company’s end-to-end project management feature will manage site development, environmental planning, grid connection, and remote operation technology. Executives point to the contract as a sign of increasing confidence in private sector expertise and ingenuity to complete complex hybrid projects on budget and on time.

For NHPC, the collaboration represents a step change in its clean energy transition. Known for hydropower, NHPC is now branching out into solar, wind, and storage, pairing battery assets with the majority of new renewables. This hybrid approach holds the promise of not just greener power, but also more reliable power—a necessity as India’s grid grows more complex with its mix of sources and variable demand.

Industry experts see the initiative as a sign of the direction India’s renewables market is headed—from one-off plants to hybrid flexible assets that can provide 24/7 low carbon power. The shift echoes state mandates for grid-forming storage in new public-sector and utility-scale renewable tenders—a development likely to deepen as the nation aims for 500 GW of non-fossil capacity by 2030.

Other wins should come in the form of jobs, technical training for regional workers, and supply chain growth around premium high-tech battery components, solar PV modules, and grid-balancing software. Environmental impact assessments and safety processes are baked into project planning, targeting minimum land use and local involvement.

Challenges abound: marrying massive BESS with India’s aged grid, sourcing batteries affordably, and watching for thermal, operational risks in peak demand. But early research from project partners indicate dependable business case economics as battery prices continue their descent and grid management software matures.

Reliance Infra’s winning bid also crates for it additional runway for expansion in India’s rapidly-evolving hybrid energy and storage market, establishing a standard for effortless synchronization of renewable generation and flexible storage. With strong government and stakeholder support, the plant will help define best practices and pave the way for future projects throughout the region.

Amid rising energy needs, climate adaptation and the transition from coal-heavy systems, Reliance Infra’s joint venture with NHPC serves as a prototype for future power infrastructure, powering both sustainability ambitions and energy independence.
