2. With renewable deployment increasing, what are the key challenges Hartek sees in ensuring reliability, power quality, and safety in hybrid or microgrid environments — and how is Hartek innovating to address them?
Integrating hybrid and microgrid systems in India requires robust solutions to address challenges of reliability, power quality, and safety. The variable nature of renewable generation creates fluctuations in voltage and frequency, while the widespread use of inverter-based resources demands new approaches to reactive power support and grid stability. Safety is equally critical, particularly with the growing adoption of battery energy storage systems (BESS), which require advanced monitoring and emergency response mechanisms.
Hartek Group, as one of India’s top three EPC players in C&I rooftop solar, has connected over 10 GW of solar capacity to the grid, demonstrating leadership in scaling the country’s renewable energy footprint. Our EPC portfolio — which includes utility-scale solar projects, GIS substations, and 765 kV transmission systems — is designed to integrate renewables seamlessly into the grid. By deploying smart inverters, modern protection relays, and SCADA-based monitoring, we ensure stable operation, minimize harmonics, and maintain consistent power quality across hybrid networks.
Energy storage remains a key focus. In line with the Central Electricity Authority’s 2025 safety guidelines, we embed multi-layered protections — advanced BMS, thermal sensors, and fire suppression systems — into our BESS projects. These measures mitigate operational risks and enhance the reliability of microgrids, enabling round-the-clock clean power delivery.
Digital solutions further strengthen our approach. Through predictive analytics, AI-driven diagnostics, and IoT-enabled asset monitoring, we are shifting operations and maintenance from reactive to proactive, reducing downtime and improving lifecycle performance.
Beyond technology, Hartek’s leadership actively advocates for policy collaboration, Make in India initiatives, and industry-led decarbonization, while fostering skill development and indigenous innovation. By combining advanced engineering, digital innovation, and stringent safety standards, we are shaping India’s solar journey responsibly, building hybrid and microgrid systems that are reliable, resilient, and future-ready aligned with our Mission 2030 strategy in solar, storage, and smart grid infrastructure.
