India’s utility-scale solar market continues to attract new investment, with Bihar emerging as another important destination for renewable energy development. In the latest development, Oriana Power has secured a major Bihar Solar EPC Project order from Bellwether and its group companies for ground-mounted solar installations across several locations in the state.
The Engineering, Procurement and Construction (EPC) assignment covers a combined solar project capacity reported at 25.138 MW/31.423 MWp, with an overall order value of approximately ₹94.5 crore.
The development adds to Bihar’s growing pipeline of solar projects and reflects the increasing geographical expansion of India’s renewable energy sector beyond the country’s traditional solar markets.
Oriana Power Wins Major Solar EPC Order
Oriana Power received a Letter of Award (LoA) to execute the solar EPC projects for Bellwether and associated group entities, including BW V Energy Pvt. Ltd., BW I Energy Pvt. Ltd. and BW III Energy Pvt. Ltd.
The projects will be developed across multiple locations in Bihar, including Barhat, MangoBandar, Shankarpur, Murliganj, Goradih, Dhuraiya, Jagdishpur and Manikpur.
According to the project details, the EPC contract is expected to be completed within six months from the date of the Letter of Award.
Such a relatively short execution period highlights the importance of efficient engineering, equipment procurement, logistics, civil works, installation and project commissioning in utility-scale solar development.
What Does a Solar EPC Project Include?
Engineering, Procurement and Construction plays a central role in the development of large solar power plants.
The engineering stage generally involves site assessment, plant layout, electrical design, structural engineering and energy-generation planning.
Procurement involves sourcing major equipment such as solar PV modules, inverters, mounting structures, transformers, cables and electrical protection systems.
Construction brings these components together through civil works, module mounting, electrical installation, testing and commissioning.
For multi-location projects such as the Bihar portfolio, project coordination becomes particularly important because equipment, manpower and construction schedules must be managed simultaneously across different sites.
Bihar’s Solar Market Is Expanding
Bihar has traditionally had a smaller renewable energy footprint compared with states such as Rajasthan, Gujarat, Karnataka and Tamil Nadu.
However, recent project activity indicates that the state is gradually increasing its solar infrastructure.
Large ground-mounted installations can help Bihar diversify its electricity supply while supporting India’s wider transition towards cleaner sources of power.
The latest Oriana Power project follows other significant renewable energy developments in the state.
75 MW Jamui Solar Project Adds Momentum
Another notable development has been the commissioning of the 75 MW Jamui Solar Power Project.
The project was developed through SJVN Green Energy Limited and is located around Hadhadiya and Kakanchaur villages in Bihar’s Jamui district.
The solar facility occupies a large land area and represents another significant addition to Bihar’s renewable energy portfolio.
Projects of this scale demonstrate how utility solar can become an increasingly important component of the state’s future electricity infrastructure.
Why Bihar Has Significant Solar Potential
Bihar’s growing electricity requirements create opportunities for additional renewable generation.
Solar projects can contribute to the state’s power requirements while reducing the carbon intensity associated with electricity generation.
Ground-mounted solar installations also offer the advantage of being developed at substantially larger capacities than most rooftop systems.
As additional projects enter operation, Bihar could benefit from:
- Increased renewable electricity generation
- Greater diversification of the state’s power mix
- New investment in energy infrastructure
- Employment during project construction and operation
- Development of supporting electrical and engineering industries
- Progress towards India’s renewable energy targets
The expansion of transmission infrastructure will also be important for efficiently integrating additional solar capacity into the electricity network.
India’s Solar EPC Market Continues to Grow
The Bihar projects are part of a much larger transformation taking place across India’s power sector.
Utility-scale solar installations, commercial and industrial projects, open-access solar and residential rooftop systems are all contributing to increasing solar deployment.
This expansion is creating opportunities throughout the solar value chain.
Solar module manufacturers, inverter suppliers, electrical equipment companies, EPC contractors, logistics providers and operations and maintenance companies can all benefit as new capacity is developed.
The EPC segment is particularly important because project performance depends heavily on engineering quality and installation standards.
Quality Equipment Matters in Large Solar Projects
The long-term performance of a solar power plant depends on much more than installed capacity.
Equipment selection, engineering design and installation quality can influence electricity generation throughout the operational life of the project.
Solar modules are generally designed to operate for decades. Therefore, selecting reliable equipment and implementing proper engineering standards during construction is critical.
Inverters, mounting structures, cables, transformers and protection systems must also be appropriately selected according to site conditions and project requirements.
Proper operations and maintenance after commissioning further help maintain plant performance.
Utility Solar and Rooftop Solar Serve Different Needs
Large projects such as the Bihar Solar EPC Project primarily contribute electricity at utility or commercial scale.
Rooftop solar, meanwhile, enables homes and businesses to generate electricity directly at their own premises.
Both models are important for India’s clean-energy transition.
Utility-scale plants can deliver substantial renewable capacity, while rooftop installations can reduce electricity consumption from the grid at the point of use.
For commercial and industrial businesses, rooftop solar can also convert unused roof areas into productive energy-generating assets.
Solar Growth Creates Opportunities for Businesses
India’s continued solar expansion is not limited to power developers.
Businesses with significant daytime electricity consumption can also participate in the transition by installing rooftop solar systems.
Factories, warehouses, hospitals, hotels, educational institutions and commercial buildings can use solar generation to reduce their dependence on grid electricity.
A correctly designed commercial solar installation can provide electricity savings over many years while supporting corporate sustainability targets.
The appropriate system capacity should be calculated based on electricity consumption, sanctioned load, available installation area and the applicable electricity regulations.

India’s Solar Expansion Is Reaching New Markets
The latest ₹94.5 crore Bihar solar EPC order demonstrates how renewable energy development is expanding across different parts of India.
With projects planned across multiple Bihar locations and additional utility-scale developments already entering operation, the state’s solar market is gaining momentum.
Continued investment in generation, transmission and supporting infrastructure could further strengthen Bihar’s role in India’s renewable-energy transition.
As India continues expanding solar capacity, both large utility projects and distributed rooftop systems will contribute towards building a cleaner, more diversified and resilient electricity system.
