EPC v/s Turnkey: What is the Difference?
Introduction: Clearing the Confusion
In the arena of infrastructure and solar energy projects, terms like EPC (Engineering, Procurement and Construction) and Turnkey are often used interchangeably. While they look familiar at the same time, they vary in scope, responsibilities and execution. From small to mid-sized businesses, these differences can help from miscommunication, unexpected price surges or delays.
This blog breaks down the ideas of EPC and Turnkey in layman’s language and helps you choose the Best Solar EPC Company for your next project.
What is EPC?
An EPC is a project delivery model in which a single contractor is responsible for the engineering (design), procurement (shopping for materials), and creation (building the project). The EPC contractor executes the venture in keeping with the purchaser’s specs and typically hands over the project when it’s ready for testing or commissioning.
Key Features:
- The contractor executes based on the customer's design inputs.
- Flexibility in choosing components and technology.
- The customer has greater control and involvement for the duration of the process.
Industries Commonly Using EPC:
- Solar Power Plants
- Roads & Highways
- Water Treatment Initiatives
- Industrial Infrastructure
Example: A solar EPC company will lay out the solar plant layout, buy solar panels and inverters, and build the setup. The customer can also be involved in choosing brands or reviewing the layout.
What is a Turnkey Contract?
A Turnkey contract refers to a venture wherein the contractor promises a totally functional, ready-to-use facility. Here, the consumer offers the initial requirements, and the contractor takes full responsibility entirety till the very last handover.
Key Features:
- The contractor takes end-to-end responsibility.
- Minimal involvement is required from the client.
- A fixed timeline and cost.
Industries Commonly Using Turnkey:
- Commercial Real Estate
- Cold Storage Units
- Data Centres
- Complete Solar Farm Setups
Example: In a turnkey solar company, the contractor handles the whole lot – site evaluation, permissions, component selection, construction, testing, and handover. The customer truly turns the important thing and starts the usage of the plant.

Industry Trends in India
India’s infrastructure and renewable electricity sectors are developing rapidly. According to the Ministry of New and Renewable Energy (MNRE), India added over 13 GW of solar capacity in 2023. More than 60% of these projects have been finished under EPC models.
However, the turnkey model is gaining traction in industries like:
- Data Centres
- EV Charging Stations
- Warehousing
These industries want quick deployment and minimum internal coordination, making turnkey a smarter preference.
