The renewable energy sector of India is expanding at a fast pace as the number of projects is increasing in solar power, wind energy, and green hydrogen projects. As these projects grow, developers need to support the infrastructure that can be built quickly and cost-efficiently. Most of the renewable energy facilities depend on buildings for operations, equipment storage, maintenance, and workforce management.
Pre-engineered buildings are a practical solution for meeting the infrastructure needs in the renewable energy sector. Since PEB components are manufactured off-site and can be assembled at the project location, it provides design flexibility and long-term durability. In this blog, we will explain how the pre-engineered building supports India’s renewable energy revolution.
India’s Renewable Energy Growth
Renewable energy is a major part of the long-term energy strategy of India, and the government has made significant investments in clean power generation. Due to favourable weather conditions, technical advancements and an increasing number of utility-scale rooftop installations. Wind energy is also important, while hybrid renewable projects are becoming popular for energy reliability.
Another emerging sector that is in demand is green hydrogen. When new renewable energy facilities are developed, the need for buildings to support workforce accommodation, maintenance and equipment storage increases. This has increased demand for construction methods that support the project timeline requirements.
Why Renewable Energy Projects Need Fast Construction
Most of the renewable energy projects are situated in the remote areas of the country. In these areas, access to labour, construction materials and other supporting infrastructure can be limited. Any delay in the construction of operational buildings for infrastructure development has the potential to postpone equipment installation, project commissioning and power generation. So the developers need construction solutions that can significantly reduce on-site work so that the projects become operational as early as possible.
Pre-engineered buildings can solve these challenges as it is constructed in a factory environment. While site foundations are being prepared, the structural components can be fabricated simultaneously. And, when the site becomes ready, the installation process can be started easily. This approach can significantly reduce the construction timelines and improve the project efficiency.
PEB vs RCC for Solar and Wind Infrastructure
Choosing between PEB and RCC for solar and wind infrastructure depends on construction speed, project cost, structural requirements, durability and future expansion needs.
| Factor | PEB | RCC |
| Speed | Faster | Slower |
| Cost | Often lower | Can be higher |
| Weight | Lightweight | Heavy |
| Labour | Less on-site work | More on-site work |
| Flexibility | Easy to expand | Harder to modify |
| Maintenance | Needs corrosion protection | Needs crack and leak repairs |
| Best for | Offices, storage and inverter rooms | Heavy-duty and permanent structures |
Why Pre-Engineered Buildings Are Preferred for Renewable Energy Projects
Pre-engineered buildings are chosen for various requirements of energy facilities as they can be built more easily, are flexible, and are durable. As the structural components are manufactured at the factory, installation of a PEB structure on-site is faster than traditional methods. So, when the project schedules are tight, supporting infrastructure can be completed more easily.
Another advantage of a pre-engineered building is the lightweight steel manufacturing. This reduces the foundation requirements, which simplifies transportation and installation. Also, the PEB buildings are easy to customise for different operational needs in the renewable energy sector. If the project requirements change in the future, then PEB structures can be expanded or modified accordingly.
What Are the Applications of Pre-Engineered Buildings in Renewable Energy Projects
Pre-engineered buildings are used in different renewable energy projects since they offer functional, durable and adaptable infrastructure. Also, the modular design of pre-engineered buildings is beneficial to the developers as they can construct essential facilities quickly and meet the operational requirements of solar parks, wind farms, and green hydrogen plants.
Solar Inverter Rooms
The equipment that converts direct current(DC) generated from solar panels to alternating current(AC) for transmission to the power grid is placed inside solar inverter rooms in the renewable energy project site. Pre-engineered buildings help to protect sensitive electrical equipment from various external factors like dust, moisture, and harsh weather conditions and provide sufficient ventilation and access for maintenance services.
Control Buildings
The operational hub of renewable energy projects is control buildings. Monitoring systems, communication equipment, control panels and electrical systems can be accommodated in such buildings. Here, operators can monitor plant performance and manage grid connections efficiently.
O&M Offices
Operations and maintenance (O&M) offices provide reliable workspace for engineers, supervisors, and technicians who ensure smooth operation of renewable energy facilities. Pre-engineered buildings can be used as offices, meeting rooms, and rest areas to support daily operations of the renewable energy project site.
Equipment Storage Sheds
Renewable energy projects usually need secure storage space for tools, spare parts, electrical components, cables, and maintenance equipment. Pre-engineered storage sheds are useful to keep these materials organised and protected from harsh environmental conditions. Also, technicians can use the equipment when maintenance work is needed.
Warehouses
Large-scale renewable energy projects need warehouses for storing essential equipment like solar modules, turbine components, batteries, and transformers. PEB buildings used as warehouses offer spacious interiors which can be customised to accommodate large storage systems, loading areas, and material handling equipment.
Worker Accommodation
Most of the renewable energy projects are located in remote areas, and temporary accommodations are needed for the construction teams. Pre-engineered buildings can be customised with comfortable accommodation facilities with sleeping areas, dining spaces, restrooms, and recreational areas.
Security Cabins
Security cabins provide a comfortable workspace for security personnel working in renewable energy facilities. Pre-engineered security cabins can be installed easily at the entry gate or at strategic locations in the project site.
Cost and Construction Timeline Comparison
PEB structures are often more cost-effective and faster to construct than RCC buildings for renewable energy facilities, although the final cost depends on design, size, location, materials and project requirements
| Factor | PEB | RCC |
| Construction cost | Often lower for large-span buildings | Usually higher for similar structures |
| Construction time | Around 8–16 weeks for medium buildings | Can take 6–18 months |
| Foundation cost | Lower due to lightweight structure | Higher due to heavier structure |
| Labour requirement | Less site labour | More site labour |
| Cost savings | Reduced wastage and faster completion | Higher formwork and material costs |
| Best suited for | Inverter rooms, warehouses, offices and storage sheds | Heavy-duty and permanent structures |
Sustainability Benefits of Pre-Engineered Buildings
Pre-engineered buildings help in faster construction and project completion at the renewable energy project site. Moreover, it also helps in promoting sustainable infrastructure development. Factory-based manufacturing improves material utilisation and reduces construction waste compared to the traditional site-based method.
Steel components used in the PEB building are also recyclable. This makes PEB buildings a more resource-efficient option for a wide variety of renewable energy projects. PEB structures use insulated panels, natural lighting, and energy-efficient ventilation systems. Also, PEB buildings have the ability to reduce site disturbance, making them well suited for renewable energy projects.
