Summary:

—-

**Notified on March 18, 2026** — This landmark policy establishes Maharashtra as India’s first state to mandate energy storage as a core requirement for renewable energy integration, fundamentally reshaping procurement, project development, and financing.

—

| Metric | Target ||——–|——–|| **RE Share by FY30** | 50% (rising to **65% by FY2036**) || **Storage Obligation by FY2036** | 10% of DISCOM demand || **RE Capacity Needed by FY2036** | 100 GW (implied equivalent) || **Storage Required by FY2036** | 100 GWh/day (~20 GW at 5-hour duration) || **Storage Charging Mandate** | Minimum **85% of stored energy must come from RE sources** annually |

—

### Co-located Storage Mandates

| Timeline | Target | Storage Requirement ||———-|——–|———————|| By FY 2029-30 | 10 GW new solar/wind/hybrid with storage | Minimum 50% of RE capacity with 2-hour duration || By FY 2035-36 | 25 GW total | Minimum 4-hour duration for projects post-FY2030 |

### Stand-Alone Storage– Technology-agnostic tenders encouraged– Storage-as-a-service and ancillary service models explicitly recognized– Pumped Storage (PSP) remains a key long-duration pathway alongside BESS

—

### Charge Relief for Storage ProjectsEnergy Storage Systems (ESS) drawing power for **in-state use** are exempt from:

| Charge Type | Waiver Status ||————-|—————|| Transmission Charges | ✓ Exempt || Distribution Demand & Wheeling Charges | ✓ Exempt || Electricity Duty | ✓ Exempt || Cross-Subsidy Surcharge | ✓ Exempt |

*This dramatically improves project economics for both co-located and stand-alone storage developers.*

### Land Availability| Land Type | Terms ||———–|——-|| **Government Land** | Nominal lease of **₹1/year for 30 years** || **Private Land** | Higher of 6% of land value or **₹1.25 lakh/hectare/year**, with **3% annual escalation** || **NA Tax/Premium** | **Fully waived** for RE and storage projects || **RE Industrial Zones** | 10 zones by FY30, 15 by FY36; **₹500 crore budgetary support** |

—

### 1. Distributed Storage (≈10% of Total Target)– Explicit earmark for **decentralized ESS** — a major distributed market signal– Targets rural feeders, critical social loads, and high-rooftop-penetration areas

### 2. Urban Solar+Storage Hubs– **100-250 MW hubs** near major cities and industrial clusters– Designed for C&I buyers seeking reliable, firm, green power– Reduces grid congestion and transmission losses

### 3. Rooftop Storage MandateFor projects >100 kW seeking connectivity from **April 1, 2026**:– Mandatory storage at **50% of RE capacity with 2-hour duration**– Existing rooftop solar projects encouraged to add storage
