In India, electricity deficits are overcome by the engineering dominance — that is what has been the ethos at the Bharat Electricity Summit 2026. Here, what emerged wasn’t event rhetoric. It was a shift in how the country is thinking about power, industry, and global positioning. Beneath the presentation numbers lay a deeper industrial signal of India building an electricity system that could redraw cost curves for energy-intensive sectors like aluminium.

Start with the baseline. India has crossed 520 GW of installed capacity, with over 40 per cent already coming from non-fossil sources. A decade ago, the country was running a power deficit of around 4-5 per cent. Today, it is operating close to surplus, with a grid sophisticated enough to handle 15-minute scheduling and increasingly layered with smart metering and digital controls.

From megawatts to markets

The Indian power sector is moving beyond capacity addition into system management. Between April 2025 and January 2026 alone, India added a record 52.5 GW of new capacity, taking total installed capacity to 520 GW. Crucially, over 52 per cent of this capacity (272 GW) now comes from non-fossil sources, compared to just 32 per cent a decade ago.
At the same time, renewable additions are accelerating faster than conventional infrastructure as India added 44.5 GW of renewable capacity in 2025, nearly double the previous year’s pace.
This scale has forced a shift in policy focus. With generation no longer the primary bottleneck, the emphasis is now on integrating variable renewable energy into the grid through storage, market-based dispatch, and digital load management, rather than simply adding more plants.

This shift is underpinned by a structural balancing act. India has already met 50 per cent non-fossil installed capacity — 5 years ahead of its 2030 target, while continuing to serve the world’s third-largest electricity demand base.
At the same time, electricity demand continues to rise alongside industrialisation and electrification, with coal still accounting for over 70 per cent of actual generation, highlighting the gap between clean capacity and reliable supply.
This creates a measurable tension: India must expand clean energy without disrupting affordability or reliability across a grid serving over a billion people.

For aluminium producers, this shift is critical as power accounts for roughly 35-40 per cent of smelting costs. The promise of sub-INR 4 per unit renewable tariffs, now increasingly paired with storage, signals an easing of input costs over the medium term.

The storage and grid equation

Of the four-day-long international conference and exhibition, Day 1 laid out ambition, Day 2 exposed the constraints, and the solutions.

Energy storage emerged as the linchpin of India’s next phase. With a roadmap targeting integration of over 900 GW of non-fossil capacity by 2035-36, storage has become foundational for the sustainable and stable power supply.

Sessions on battery ecosystems, grid flexibility, and decentralised generation underscored a hard truth: renewable expansion without storage simply shifts volatility across the system.
