India energy storage policy framework: where the rules actually are in 2026
India's energy storage policy framework spans MNRE, CERC, MoP, and CEA — without a single comprehensive statute. Key 2025–2026 developments include CERC ancillary services regulation, draft Energy Storage Obligation policy, and PLI for advanced cell manufacturing. The fragmentation creates predictable regulatory friction for developers.
In 50 words: India's energy storage policy framework spans MNRE, CERC, MoP, and CEA without a single comprehensive statute. Key 2025–2026 developments: CERC ancillary services regulation, draft Energy Storage Obligation policy, PLI for advanced cell manufacturing. The fragmentation creates predictable regulatory friction for developers.
The fragmented landscape
Energy storage policy in India is spread across:
- MNRE: scheme design for hybrid PPA, viability gap funding, PLI for ACC manufacturing
- CERC: market participation rules, ancillary services framework, tariff policies for storage
- MoP: Energy Storage Obligation (draft), Resource Adequacy framework
- CEA: technical standards, grid code integration
- State SERCs: state-level retail tariff structures affecting BTM BESS economics
Key 2025–2026 developments
- CERC Ancillary Services Regulation (March 2026) — opened revenue stacking for BESS in primary, secondary, and tertiary reserves
- Draft Energy Storage Obligation Policy — would mandate DISCOMs procure minimum storage capacity, modeled on RPO
- PLI for ACC manufacturing — Phase 2 round expected in H2 2026
- MoP Resource Adequacy Framework draft — would mandate firm capacity contracting, indirectly favouring storage
- MNRE Standalone BESS tender Series IV — June 2026 expected, building on the 4.2 GW awarded in Q1
What's missing
The absence of a comprehensive Energy Storage Act creates:
- Definitional ambiguity (is BESS a generator, a transmission asset, or both?)
- Tax treatment uncertainty (GST classification varies by state)
- Land use classification disputes
- Insurance and lender underwriting complexity
What developers should know
For 2026 BESS projects:
- Standalone merchant BESS: revenue stacking now possible under CERC rules
- Hybrid solar+BESS: SECI PPA framework is well-developed
- BTM BESS: state-level tariff structures dominate; check ToD and demand charges
- Captive BESS: increasingly relevant for corporate renewable procurement
What's coming
Expected through 2026–2027:
- Formal Energy Storage Obligation notification (would create guaranteed demand)
- BESS-specific tariff structures from major SERCs
- ALMM-equivalent quality framework for BESS systems
- Updated CEA grid integration standards for grid-forming BESS
What to watch next
The Energy Storage Obligation notification timing — currently in stakeholder consultation — could be the single most consequential storage policy of the decade in India. Notification expected before end of FY 2027.
