Government Takes Multi-Pronged Steps to Scale Up Energy Storage Capacity in the Country

1. At a Glance

• India's transition to a high-RE grid hinges on firming intermittent solar/wind with storage; CEA pegs the 2029-30 storage need at 60.63 GW / 336.4 GWh [S1][S2].
• The Centre is using a policy + fiscal + regulatory bundle (national framework, VGF, PLI-ACC, ISTS waiver, Energy Storage Obligation) — a classic GS-III "Energy/Infrastructure" case study [S1][S2].
• Relevant for Prelims (schemes, ministries, numbers) and Mains (energy transition, federal financing, climate commitments).

2. Why in the News

• 3 February 2026 PIB release by Ministry of New and Renewable Energy (MNRE) titled "Government Takes Multi-Pronged Steps to Scale Up Energy Storage Capacity" consolidating measures for PSP and BESS rollout [S1].
• Follows June 2025 Cabinet/Ministry of Power approval of a ₹5,400 crore VGF for an additional 30 GWh BESS funded through the Power System Development Fund (PSDF) [S2].

3. Background & Evolution

• August 2023: Ministry of Power issued the National Framework for Promoting Energy Storage Systems [S3].
• September 2023: Cabinet approved the VGF Scheme for BESS (originally 4,000 MWh by 2030-31, up to 40% capital cost) [S2].
• March 2024: VGF scheme operationalised with ₹3,760 crore outlay for 13,220 MWh at ₹27 lakh/MWh [S2].
• June 2025: Additional 30 GWh BESS VGF via ₹5,400 crore PSDF at ₹18 lakh/MWh [S2].
• 2026: MNRE consolidates measures including ISTS waiver and ESO trajectory [S1].

4. Core Static Facts

• Source document: CEA Report on "Optimal Generation Mix 2030" [S1].
• Storage need by 2029-30: 60.63 GW = 18.98 GW PSP + 41.65 GW BESS; 336.4 GWh = 128.15 GWh PSP + 208.25 GWh BESS [S1][S2].
• Nodal Ministry: MNRE (with Ministry of Power for transmission/regulatory matters) [S1].
• Key Instruments:
• Guidelines for Procurement & Utilisation of BESS as Gen/Trans/Discom & Ancillary asset [S1].
• National Framework for Promoting Energy Storage Systems (Aug 2023) [S3].
• Guidelines to promote Pumped Storage Projects (PSP) [S1].
• 100% ISTS charges waiver — PSPs awarded on or before 30 June 2028; same for co-located BESS [S2].
• Energy Storage Obligation (ESO) trajectory: 1% (FY24) → 4% (FY30), +0.5% p.a.; ≥85% of energy stored must come from RE [S2].
• PLI-ACC (Advanced Chemistry Cell) scheme of Ministry of Heavy Industries supports domestic battery manufacturing [S1].
• Statutory anchor: Electricity Act, 2003 + CERC/SERC regulations.

5. Multi-Dimensional Analysis

Economic - VGF lowers tariff: discovered storage cost was ₹10.18/kWh before VGF/PLI interventions [S2]. - Total VGF commitment so far: ₹3,760 cr (13.2 GWh) + ₹5,400 cr (30 GWh) [S2]. - ESO creates assured offtake demand for storage investors.

Environmental / Climate - Storage is critical to meet 500 GW non-fossil capacity by 2030 and net-zero by 2070 pledges under UNFCCC [S4]. - Enables higher RE penetration without curtailment, reducing reliance on coal-fired balancing.

Scientific / Technological - Twin-track: PSP (mature, long-duration) + BESS (Li-ion, modular, fast response). - PLI-ACC (50 GWh) targets indigenisation; reduces import dependence on China for cells [S1].

Administrative / Federal - ISTS waiver is a central lever; DISCOMs (State) must sign PPAs/ESPAs — MNRE actively facilitating PPA signing [S1]. - ESO is enforced via SERCs; uneven state compliance is a bottleneck.

Geostrategic - Battery supply chain (Li, Co, Ni) ties into Critical Minerals Mission 2025 and KABIL's overseas acquisitions.

6. Recent Developments (last 12-18 months)

• 3 Feb 2026: MNRE consolidation release on multi-pronged steps [S1].
• June 2025: ₹5,400 cr VGF for 30 GWh BESS via PSDF [S2].
• 2024: ISTS waiver extended to co-located BESS commissioned by 30 June 2028 [S2].
• March 2024: First VGF tranche operationalised (13,220 MWh) [S2].

7. Prelims Hooks

• CEA report "Optimal Generation Mix 2030" projects 60.63 GW storage need by 2029-30 [S1].
• Of this, 18.98 GW PSP + 41.65 GW BESS [S1].
• Total energy storage need: 336.4 GWh [S2].
• National Framework for Promoting ESS issued in August 2023 by Ministry of Power [S3].
• VGF for BESS: ₹3,760 cr for 13,220 MWh at ₹27 lakh/MWh (2024) [S2].
• Second VGF: ₹5,400 cr for 30 GWh at ₹18 lakh/MWh via PSDF (2025) [S2].
• ISTS waiver valid for PSP/BESS awarded by 30 June 2028 [S2].
• ESO trajectory: 1% in FY24 → 4% in FY30, rising 0.5% annually [S2].
• ESO compliance requires ≥85% RE-sourced stored energy [S2].
• PLI-ACC is administered by Ministry of Heavy Industries (not MNRE) [S1].
• At least 85% of VGF-funded BESS output must first be offered to DISCOMs [S2].
• Nodal ministry for the Feb 2026 release: MNRE [S1].

8. Mains Relevance

• GS-III: Infrastructure — Energy; Environment — Climate change mitigation; Indian Economy — Investment models.
• GS-II: Government policies for sectors; Centre-State relations (DISCOMs).
• Possible question stems:
• "Energy storage is the missing link in India's renewable energy transition. Examine the policy and fiscal architecture being built to bridge it."
• "Discuss the role of Viability Gap Funding and Energy Storage Obligations in de-risking BESS investments in India."
• "Compare Pumped Storage Projects and Battery Energy Storage Systems as instruments of grid balancing in India's net-zero pathway."

9. Related Topics to Study Next

• National Electricity Plan 2023 — projects 236 GWh BESS by 2031-32 [S2].
• PLI Scheme for Advanced Chemistry Cells (50 GWh) — manufacturing leg of storage push.
• Green Hydrogen Mission — competing/complementary storage vector.
• CERC regulations on Ancillary Services — market design context.
• Renewable Purchase Obligation (RPO) — parallel obligation regime.
• Critical Minerals Mission, KABIL — upstream supply chain for batteries.
• One Sun One World One Grid (OSOWOG) / ISA — international RE integration.
• Discom finances & RDSS — without solvent buyers, storage PPAs stall.

10. Common Errors / Trap Areas

• Ministry confusion: National Framework (Aug 2023) was issued by Ministry of Power, not MNRE; PLI-ACC by Ministry of Heavy Industries.
• Number mix-up: 60.63 GW is capacity; 336.4 GWh is energy — not interchangeable.
• ESO ≠ RPO: ESO is sub-set of obligations specific to stored energy; trajectory peaks at 4% by FY30 (not 10% or higher).
• ISTS waiver cut-off: it is 30 June 2028 (commissioning/award date) — not 2030.
• Source document name: "Optimal Generation Mix 2030" is by CEA, not NITI Aayog.
