Why Union Budget 2026 Matters for the Energy & Power Sector
For over a decade, India’s energy policy revolved around one clear metric: capacity addition. Megawatts added became the headline number. However, as renewable penetration rises beyond 40 percent in several states, the conversation is finally changing.
Union Budget 2026 is expected to reflect this maturity. The focus is shifting from just adding green capacity to ensuring grid stability, round-the-clock availability, and energy security. This transition has meaningful implications for listed power, energy, capital goods and infrastructure companies.
For investors tracking the Union Budget 2026 Energy & Power Sector Outlook, this is less about ideology and more about execution.
Battery Energy Storage Systems: Storage Is King
Among all budget expectations, Battery Energy Storage Systems are emerging as the single most critical theme. India’s renewable push has created a new problem: power is available, but not always when needed.
Solar peaks during the day. Wind is seasonal. Demand peaks in the evening.
This mismatch is where battery storage becomes essential.
What the industry expects
- Faster rollout of Viability Gap Funding for BESS projects
- Reduction in GST on batteries from 18 percent to align with electricity which is exempt
- Long duration storage tenders by SECI and state discoms
Market impact
A GST rationalisation alone can materially improve project IRRs. Companies involved in storage solutions, EPC players, and grid-linked infrastructure providers stand to benefit. Over time, BESS also reduces discom stress by lowering peak power procurement costs.
Real world example: States like Tamil Nadu and Karnataka have already begun piloting storage-linked renewable tenders, signalling what could scale nationally post Budget.
Green Hydrogen and the SIGHT 2.0 Push
The National Green Hydrogen Mission remains a long-term strategic pillar, and Budget 2026 is expected to deepen this commitment rather than expand it blindly.
The focus is likely to be sharper execution through the SIGHT program.
Key expectations
- Continued allocation for SIGHT Phase 2
- Targeted incentives for electrolyser manufacturing
- Support to reduce reliance on imported electrolysers
Why this matters
Electrolysers account for a large part of green hydrogen project costs. Domestic manufacturing can significantly lower costs and improve scalability. This also aligns with India’s broader manufacturing and self-reliance goals.
For investors, this creates opportunities across industrial gases, capital goods, and select renewable companies positioning for hydrogen value chains.
Transmission Capex: Solving the Evacuation Bottleneck
Adding renewable capacity is meaningless if power cannot reach consumption centres. This is where transmission infrastructure becomes the unsung hero of the energy transition.
Union Budget 2026 is expected to allocate meaningful capital towards Green Energy Corridor Phase III.
Focus areas
- Rajasthan and Gujarat renewable evacuation
- Inter-state transmission systems
- Grid modernisation and balancing infrastructure
Investment relevance
Transmission projects offer regulated returns, long visibility, and relatively lower risk. Increased capex here benefits power grid operators, EPC companies, and electrical equipment manufacturers.
From a market standpoint, this improves renewable project viability and reduces stranded capacity risks.
Solar Manufacturing: Moving Up the Value Chain
India’s Production Linked Incentive scheme has helped kick-start domestic module assembly. However, dependence on imported upstream components remains high.
Budget 2026 may address this gap.
Expected policy direction
- PLI expansion to polysilicon, ingots and wafers
- Incentives for integrated manufacturing
- Reduced vulnerability to global supply disruptions
Why markets care
Upstream integration improves margins, stabilises supply chains, and strengthens India’s competitiveness against Chinese dominance. Over the medium term, this can reshape profitability dynamics within the solar manufacturing ecosystem.
