Maharashtra Mandates 100 GWh of Storage in Sweeping New Renewable Policy

• What happened: India's Maharashtra state has issued a landmark renewable energy policy requiring all new projects above 100 kW to integrate battery storage capacity, effective April 1, 2026. The initial requirement is set at 50% of project capacity for a minimum of two hours, with a total mandate of 100 GWh of storage statewide.
• Why it matters: This is one of the most aggressive storage-pairing mandates enacted by any subnational government. By tying storage directly to new renewable capacity, Maharashtra is addressing grid stability concerns that have historically slowed large-scale renewable integration in India. The policy sets a template other Indian states may follow.
• Scale: 100 GWh mandatory storage target; applies to all new renewable projects above 100 kW from April 1, 2026.

U.S. Interior Bends on Solar, But Wind on Public Lands Remains Stalled

• What happened: The U.S. Interior Department has shown some willingness to advance solar energy permitting on public lands, but wind energy projects that were in the Biden-era Bureau of Land Management (BLM) pipeline have largely been dropped from the permitting queue entirely.
• Why it matters: With U.S. electricity demand rising, the continued stall on wind permitting on public lands represents a significant bottleneck for the energy transition. The divergence between solar and wind treatment signals a politically driven bifurcation in federal clean energy policy, which could have long-term consequences for energy mix diversification and grid reliability.
• Scale: Most Biden-era BLM wind farm applications are no longer active in the permitting pipeline, according to E&E News.

India's National Green Hydrogen Mission Approaches $2/kg Cost Target

• What happened: India's green hydrogen production costs have hit record lows, driven by policy support under the National Green Hydrogen Mission and scaled-up deployment. The country is now within striking distance of its ambitious $2/kg production cost target.
• Why it matters: The $2/kg threshold is widely considered the point at which green hydrogen becomes economically competitive with fossil-fuel-derived hydrogen at scale. India reaching this benchmark would mark a major inflection point for the global hydrogen economy and could position the country as a major green hydrogen exporter. The trajectory also signals that large-scale policy commitments — rather than technology alone — are the key driver of cost reduction.
• Scale: National-level mission; record-low auction prices driving cost trajectory toward $2/kg.

Global Solar Panel Market Growth Fueled by Surging Adoption

• What happened: A new market analysis published March 20, 2026 projects that the global solar panel industry is on a strong growth trajectory, driven by expanded use across residential, commercial, and industrial segments, alongside rising demand for renewable energy sources.
• Why it matters: The report underlines that solar remains the dominant driver of new renewable capacity worldwide. The combination of falling manufacturing costs, policy incentives, and rising electricity demand is sustaining market expansion even amid political headwinds in some jurisdictions.
• Scale: Global renewable energy market projected to reach $1,571.93 billion by 2032, growing at a 9.1% CAGR.

Policy & Regulation

• India (Maharashtra): Effective April 1, 2026, all new renewable energy projects above 100 kW must integrate battery storage at 50% of project capacity for at least two hours, as part of a sweeping new state energy policy targeting 100 GWh of total storage.

• United States: The Interior Department is advancing some solar permitting on federal public lands but has effectively stalled wind energy development — most Biden-era BLM wind projects are no longer in the permitting pipeline, creating uncertainty for the wind sector even as electricity demand climbs.

• India (National): The National Green Hydrogen Mission is delivering measurable cost reductions, with production prices approaching the landmark $2/kg target that would make green hydrogen cost-competitive with fossil alternatives.

Investment & Finance

• ATCO (Canada/Alberta): ATCO, the Calgary-based energy conglomerate, has devalued its wind and solar project portfolio by $408 million CAD due to Alberta's provincial power policy reforms. ATCO warned of potential "legal recourse" if the province does not alter the reforms that are harming its renewable assets.

• AlphaESS / Energy Spurt (Australia): AlphaESS and distribution partner Energy Spurt have unveiled a new line of battery storage systems specifically designed to qualify for Australia's 2026 federal rebate programs. The partnership aims to help Australian households and businesses maximize savings under the new subsidy era.

India's Battery Storage on Track for 346 GWh by 2033

A new industry paper published this week projects that India's installed battery energy storage capacity will reach 346 GWh by 2033, up dramatically from current levels. The growth is being driven by government initiatives — including the Maharashtra storage mandate and the National Green Hydrogen Mission — alongside rapidly increasing demand for grid flexibility as variable solar and wind generation expands. Battery energy storage systems (BESS) are cited as the primary vehicle for this scale-up, with Indian grid operators increasingly requiring storage to accompany new renewable capacity.

RenewSys Commissions 3 GW Solar Module Factory in Maharashtra

Indian solar manufacturer RenewSys commissioned a new 3 GW solar module manufacturing facility in Maharashtra this week, bringing the company's total module production capacity to 5.6 GW. The facility expansion also follows a February 2026 agreement with ENGIE to supply 125 MWp of modules. The commissioning adds significant domestic manufacturing capacity at a moment when India is pushing hard to reduce dependence on imported solar components.

What to Watch Next Week

• Alberta policy standoff: Watch for any response from the Alberta provincial government to ATCO's $408 million writedown and legal threats — this dispute could set a precedent for how Canadian provinces handle retroactive changes to renewable energy policy frameworks.
• Maharashtra storage implementation: As April 1, 2026 approaches, track whether developers and regulators in Maharashtra publish implementation guidance for the new 100 GWh storage mandate — particularly how compliance will be measured for projects already in the pipeline.
• India green hydrogen auctions: With production costs approaching $2/kg, watch for new tender announcements under the National Green Hydrogen Mission that could lock in competitive pricing and accelerate deployment timelines.
