Mohali, Punjab | October 2026: Hartek Group, a leading Engineering, Procurement and Construction (EPC) company in India’s power and renewable energy sector, continues to strengthen its engineering and execution capabilities across utility-scale solar projects and high-voltage transmission infrastructure. With expertise spanning renewable energy generation, grid connectivity and extra-high-voltage substations, the company is supporting the development of infrastructure required to meet India’s growing electricity demand.

As India accelerates renewable energy deployment, the need for coordinated development of solar generation and transmission networks is becoming increasingly important. Utility-scale solar projects require more than generation capacity alone. Effective engineering, power evacuation planning, substation development and grid interconnection are essential to transferring electricity from generation sites to the wider power network.

Strengthening Utility-Scale Solar EPC Capabilities

Hartek’s Renewables business delivers engineering, procurement and construction solutions for large-scale solar projects. Its capabilities cover key project stages, including engineering design, equipment procurement, construction coordination, grid interconnection and commissioning, subject to the requirements of each project.

In July 2026, Hartek Power secured a 400 MW utility-scale solar EPC project in Rajasthan. The project comprises two solar power plants of 200 MW each, with a combined capacity of 299.2 MW AC and 400 MW DC. The scope also includes grid interconnection, management of owner-supplied equipment and final commissioning.

The project reflects the growing importance of engineering coordination in large renewable energy developments. From site-specific design considerations to equipment integration and commissioning, each stage requires careful planning to support project performance, quality and timely execution.

Hartek has connected more than 10 GW of solar capacity to the national grid, strengthening its position in India’s renewable energy EPC sector. Its experience across utility-scale and other solar segments supports the company’s continued participation in the country’s expanding clean energy infrastructure.

Advancing Transmission and Substation Infrastructure

Transmission infrastructure plays a critical role in enabling renewable energy projects to deliver electricity to the grid. High-voltage and extra-high-voltage substations facilitate power transfer, while effective network planning helps address the connection requirements of new generation capacity.

Hartek’s Power Systems business has delivered more than 400 EHV and HV substation and turnkey projects across over 21 Indian states, with operational capabilities extending up to 765 kV. Its services include engineering, procurement, construction, testing and commissioning for power transmission and distribution projects.

The company’s transmission portfolio includes a ₹138 crore contract awarded by Power Grid Corporation of India Limited in 2025 for a 400 kV air-insulated substation package associated with renewable energy zone integration in Karnataka. The project demonstrates the importance of transmission infrastructure in connecting renewable generation to the wider electricity network.

By developing capabilities across solar EPC and high-voltage power systems, Hartek is positioned to contribute to projects where generation infrastructure and grid connectivity must be planned and executed in coordination.

An Integrated Approach to Power Infrastructure

The growing scale of renewable energy deployment is increasing the need for coordination among developers, engineering teams, equipment suppliers, utilities and transmission stakeholders. Design accuracy, procurement planning, construction management, testing and commissioning all influence the delivery of complex infrastructure projects.

Hartek’s presence across Power Systems, Renewables and Power Distribution Products brings together capabilities across multiple segments of the energy value chain. This portfolio supports its work across grid infrastructure, renewable power generation and electrical distribution solutions.

As India expands its clean energy capacity, continued investment in transmission networks and grid integration will remain important to ensuring that new generation assets can connect effectively with the power system.

Supporting India’s Evolving Energy Needs

Established in 1991, Hartek Group continues to participate in India’s power infrastructure development through its engineering, procurement and construction capabilities. With more than 10 GW of solar capacity connected to the grid and over 400 EHV and HV substation projects delivered, the company brings experience across renewable generation and high-voltage infrastructure.

Through continued development of its engineering and project execution capabilities, Hartek Group aims to contribute to the infrastructure needed for India’s evolving energy landscape, supporting the expansion of renewable energy and the development of transmission networks that connect generation with demand.
