Automation and digitisation advancing grid stability

Grid-scale BESS stores surplus energy for use during periods of low renewable output, enhancing grid flexibility and stability.

Due to increasing renewable energy integration, the power grid is evolving into a more distributed system. Learn more from Sanjiv Prasad from Reliance.

How can automation and digitisation stabilise power grids with increasing renewable energy integration variability?

The power grid is evolving from a centralised system to a distributed network due to renewable energy integration’s increasing variability and capacity. This transformation demands advancements in automation and digitisation to provide generators and distributors with real-time data access. Such innovations enable better management of generation variability, ensuring stable grid operations. By incorporating these technologies, the grid can support a seamless transition to renewable energy while maintaining sustainability and adaptability for future changes. These advancements are critical in balancing supply and demand, optimising performance, and fostering a resilient energy ecosystem aligned with global renewable energy goals.

How can power reliability be enhanced through T&D automation and energy storage solutions?

T&D (Transmission and Distribution) automation plays a crucial role in improving the reliability of power delivery and reducing outages. Key elements include developing solutions through advanced design and engineering, integrating substations with SCADA systems for real-time communication, and upgrading electrical control systems using numerical relays, advanced switchgear, and diagnostics. These measures enhance operational efficiency, fault detection, and response times.

The growing adoption of renewable energy sources, characterised by intermittent power generation, highlights the need for balancing resources like energy storage to maintain grid stability. By 2030, India aims to install approximately 34 GW (136 GWh) of battery energy storage systems (BESS).

BESS integration can occur at various levels. Behind-the-meter BESS provides backup during outages and stores excess rooftop solar photovoltaic (PV) generation, catering to residential and commercial users. On a larger scale, grid-scale BESS stores surplus energy for use during periods of low renewable output, enhancing grid flexibility and stability.

While pump hydro storage remains geographically constrained, BESS is expected to witness significant growth post-2030 due to decreasing capital costs and increased renewable energy deployment. These advancements are pivotal in transitioning to a sustainable, resilient, reliable energy future.

How can India overcome rural electrification challenges and ensure sustainable energy access for all?

The rural electrification in India faces challenges such as high T&D losses, frequent grid disruptions and the financial strain of extending grids to remote sparsely populated villages with low peak loads. The poor financial health of state electricity boards further exacerbates the issue hindering sustainable energy access for rural and remote communities. Access to electricity in remote areas has been regarded as synonymous with rural electrification, implemented through the grid extension. Rural electrification is a declared objective of India’s central and state governments and has been accorded high priority.

NEP emphasises that for decentralised electricity generation, both renewable energy-based and conventional (non-renewable) technologies, whichever is suitable and economical, would be deployed. It envisages achieving targeted expansion in access to electricity for rural households in the desired time frame.

How can the upcoming Union Budget drive innovations in sustainable infrastructure development, and how do you see Elecrama?

The Union Budget 2025-26 is expected to prioritise tax reforms, infrastructure development, and incentives for sustainable growth, with higher allocations for renewable power, EV charging infrastructure, and eco-friendly housing. It may also offer tax relief for green finance, such as exempting income from green bonds. ELECRAMA, scheduled from February 22–26, 2025, will showcase the latest innovations in electrical and allied industries. Key takeaways will include advancements in sustainable energy, fostering a greener and more resilient energy ecosystem, and innovations in renewable energy and storage technologies. These trends will shape the future of clean, efficient energy solutions.
