Turnkey Power Generation Projects Built for Indian Site Conditions

Rai Power delivers complete EPC solutions for captive and standby power generation projects across India.

From equipment selection and system engineering to supply, installation, testing and commissioning, we help customers build dependable power systems for industrial, commercial, infrastructure, hospitality, healthcare, government and critical applications.

With over 70 years in the power generation industry, Rai Power brings together engineering experience, OEM relationships, project execution capability and practical site knowledge — helping customers move from project requirement to reliable commissioned power.

Our Legacy

Three Generations in
Indian Power Generation

Experience That Goes Beyond Equipment Supply

Rai Power has grown with India’s power generation industry for over seven decades.

What began as a power equipment and engine-support business has evolved into a complete power solutions company with capabilities across generating systems, EPC projects, technical services and spares support.

This matters because a power project does not end with equipment dispatch. It has to be selected correctly, engineered for the site, installed safely, commissioned properly and supported during operation.

Rai Power brings this full power generation understanding into every EPC project.

Site Engineering

Built for Indian
Site Conditions

Practical Engineering for Real Project Environments

Indian power projects are rarely textbook installations. Sites may have limited DG room space, difficult unloading access, changing civil conditions, consultant revisions, acoustic restrictions, ventilation challenges, fuel system constraints and tight commissioning timelines.

Rai Power designs and executes projects with these realities in mind.

Our focus is simple: the system should not only fit on paper — it should work reliably at site.

We help customers address practical site issues such as: 

01

Limited DG room space

Layout planning that works within tight room footprints and equipment access constraints.

06

Fuel piping & day tank

Fuel tank, day tank and piping layout planned for safe, efficient operation.

02

High ambient temperature

Ventilation and cooling planning suited to high ambient site temperatures.

07

Cable routing

Cable routing, trenches and termination planning coordinated with site layout.

03

Ventilation & hot-air discharge

Airflow paths designed to prevent hot-air recirculation around the genset.

08

Earthing

Earthing space and safety considerations built into the layout.

04

Exhaust routing

Exhaust routing and stack coordination planned with the site's structure.

09

Coordination with civil, electrical, HVAC & MEP teams

Close coordination with civil, electrical, HVAC, fire and MEP contractors.

05

Acoustic control

Acoustic treatment and noise control matched to site restrictions.

10

Maintenance access

Space reserved for future maintenance access.

Compliance

Compliance-Aware
Project Execution

Designed with Safety, Emissions and Documentation in Mind

Power generation projects in India must be executed with attention to applicable statutory, environmental, electrical and site-specific requirements.

Rai Power supports customers with technical inputs, documentation and execution aligned with relevant project requirements, including CPCB emission and noise norms, CEA electrical safety requirements, electrical inspectorate expectations, consultant specifications and site-level compliance needs.

CPCB emission & noise requirements

Technical inputs aligned with applicable CPCB emission and acoustic norms.

CEA electrical safety requirements

Engineering execution aligned with CEA electrical safety expectations.

Electrical inspectorate support

Coordination and documentation support for inspectorate review and approvals.

Consultant specifications

Execution planned to align equipment and layout with consultant specifications.

Testing & handover documentation

Testing, commissioning and handover records prepared for customer records.

  • Technical submittals
  • Equipment datasheets
  • General arrangement drawings
  • Acoustic & exhaust details
  • Panel & control system details
  • QAP & inspection requirements
  • FAT / inspection coordination
  • Dispatch documentation
  • Testing & commissioning reports
  • Handover documents

Project Coordination

Working with Consultants,
PMCs and Project Teams

Clear Coordination Across the Project Chain

Many power projects in India are consultant-led, BOQ-driven and dependent on coordination between multiple agencies. A technically sound solution can still face delays if scope boundaries, drawings, approvals, site readiness and documentation are not managed properly.

Rai Power works closely with project stakeholders to reduce these gaps.

Reducing Execution Risk in Power Projects

Solving the Gaps That Commonly Affect DG Projects

Power projects often face problems because equipment supply, low-side works, installation and commissioning are handled by different teams with limited accountability.

We help customers avoid common project issues such as:

  • Incorrect sizing or configuration
  • Incomplete low-side scope
  • Panel and synchronisation issues
  • Poor ventilation and overheating
  • Difficult service access
  • Delays due to documentation gaps
  • Inadequate acoustic planning
  • Exhaust and fuel system constraints
  • Poor coordination between supplier, contractor, consultant and site team

Rai Power’s Role Rai Power helps reduce these risks by bringing power generation knowledge and project
execution experience together.

Our project approach is built around one practical belief: a power system should be properly engineered, properly installed and practical to operate after commissioning.
