A new analysis by Ember shows that solar energy, combined with battery storage, could meet up to 90% of India’s electricity demand at a lower cost than what most states currently pay for power. The findings highlight a major shift: clean energy is no longer just sustainable—it is becoming the most economical option.
India’s solar journey has already begun, but the real opportunity lies in scaling it up and making it available round the clock.
India’s Solar Potential Is Massive but Underused
India’s cumulative solar capacity as of March 2026 was 150.26 GW. While this sounds significant, the Ember report states that it represents only about 4% of the country’s estimated 3,343 GW ground-mounted solar potential. In simple terms, India has barely tapped into its solar resources.
This untapped capacity is enormous. The total feasible solar potential could generate nearly three times the country’s electricity demand in 2024. Even more striking, this estimate uses only a small portion of available land—just 6.7% of suitable wasteland, which is less than 1% of India’s total land area.
Moreover, this figure excludes other major opportunities. Rooftop solar alone could add over 600 GW, while floating solar projects may contribute up to 300 GW. Technologies like agrivoltaics, which combine farming with solar panels, could further expand capacity.
Solar power is already making a visible impact. In 2025, it contributed 9.4% of India’s electricity. During peak sunny hours, it met nearly a quarter of demand. However, the challenge remains clear: solar stops working after sunset. To fully unlock its potential, India must solve the “night problem.”
Why Solar + Storage Makes 90% Clean Power Possible
Now, battery storage is the missing piece. It allows excess solar power generated during the day to be stored and used at night. Thanks to falling battery costs, this solution is now economically viable.
- According to Ember’s modeling, solar combined with batteries can meet up to 90% of India’s electricity demand at a levelized cost of electricity (LCOE) of about INR 5.06 per kWh. This is cheaper than the average power purchase cost in many states today.
However, reaching 100% solar is not as simple. Each additional percentage beyond 90% requires significantly more solar panels and storage capacity. This leads to rising costs, making 90% the most practical and cost-effective target.
To meet this level of demand, India would need around 930 GW of solar capacity. This is still less than one-third of its total feasible ground-mounted potential. Alongside this, about 2,560 gigawatt-hours (GWh) of battery storage would be required.
In practical terms, for every 1 GW of average demand, the system would need about 4.9 GW of solar capacity and 13.5 GWh of storage.

Seasonal Patterns Shape Solar Performance
Solar energy does not perform the same way throughout the year. Its effectiveness depends heavily on seasonal patterns and weather conditions.
The Ember report further highlighted that during the early months of the year, from January to April, solar radiation is strong. In this period, solar and batteries can meet nearly 100% of daily electricity demand. Batteries store excess energy during the day and release it at night, ensuring a stable supply.
In peak summer months like May and June, electricity demand rises by about 10%. Even then, solar and storage can still meet around 88% of demand.
The real challenge appears during the monsoon season. Cloud cover reduces solar output significantly, especially in July. During this time, solar and batteries can meet only about 66% of demand.
This limitation is not due to battery capacity. Instead, it is caused by reduced solar generation over several cloudy days. Batteries can shift energy from day to night, but they cannot store large amounts of power for extended low-sunlight periods.
This is why a balanced energy mix is essential.
Wind and Hydro Will Fill the Gaps
India does not need to rely on solar alone. Other clean energy sources can complement solar power effectively.
Wind energy is especially important. It tends to generate more power during the monsoon months, when solar output is low. This natural balance helps stabilize the overall energy system.
Hydropower and nuclear energy can also provide steady, reliable electricity. Together, these sources reduce the need for excessive solar and battery capacity, keeping costs under control.
As a result, solar becomes the backbone of the system, while other clean sources fill in the gaps. Looking ahead, solar will play a major role in meeting energy demand. Around 50% of India’s additional electricity demand through 2030 is expected to come from solar power.
State-Level Trends Show Strong Potential
The feasibility of solar-plus-battery systems varies across states. This depends not only on sunlight availability but also on how and when electricity is used.
States like Andhra Pradesh, Maharashtra, Karnataka, Telangana, and Tamil Nadu show strong alignment between solar generation and electricity demand. In these regions, demand peaks during sunny months, making it easier for solar to meet a large share of electricity needs.
For example, demand in these states is often 10% to 29% higher than average during high-solar months. At the same time, demand drops during the monsoon, which helps offset lower solar output.
Other states like Gujarat, Rajasthan, and Madhya Pradesh also show favorable conditions. Their demand remains relatively stable throughout the year, which makes solar integration smoother.
However, not all states are equally suited. Uttar Pradesh and West Bengal face more challenges. In these regions, electricity demand peaks during the monsoon, when solar output is weakest. This mismatch makes it harder for solar-plus-storage systems to meet demand efficiently.
These differences explain why the same solar and battery setup performs better in some states than others.
Transmission Will Unlock National Benefits
India’s renewable energy strategy already reflects a smart approach. Large-scale solar projects are being developed in high-resource states with strong sunlight and available land. At the same time, the country is expanding its transmission network to move electricity across regions.
This interconnected system allows solar-rich states to supply power to areas with higher demand or lower solar potential. It also improves the overall efficiency of the grid.
As transmission infrastructure grows, the benefits of solar and storage will spread across the country.
The analysis makes one thing clear: India has the resources to transform its power system. Solar energy, backed by battery storage, can deliver clean, reliable, and affordable electricity at scale.
- In the broader context, the Asia-Pacific region led the global BESS market, generating USD 17.31 billion in 2025 and expected to reach USD 21.32 billion in 2026.
However, the transition will require careful planning. Seasonal variations, regional differences, and the need for complementary energy sources must all be considered.
Still, the direction is clear. With falling costs and abundant resources, solar plus storage is no longer a future possibility—it is a present-day solution.
India now stands at a turning point. By scaling up solar and investing in storage and grid infrastructure, the country can move closer to a low-cost, low-carbon energy system that meets demand day and night.

Nature-based carbon investments deserve consideration when they address a specific business dependency and produce outcomes you can measure. Imagine Moonbucks, a global coffee roaster planning next season’s espresso blend. It is considering natural Grade 4 coffee from Jimma, in southwestern Oromia, Ethiopia. Its sourcing decisions affect the roasting schedule and the cash tied up in coffee purchases. Moonbucks needs to understand which measures could protect that supply, what they would cost and how it would judge the results.
1. Define the sourcing problem before choosing a project
Moonbucks needs a dependable component for its espresso blend. Its procurement team wants continuity of volume and an agreed cup profile. Replacing a shipment at short notice could require new sample approval and changes to the blend, and given the schedules for cultivation, processing, and freight delivery, is practically impossible. Moonbucks needs to get this right, and its initial concern is inconsistent deliveries. It commissions an assessment of the supplying farms and post-harvest chain. The questions cover land condition, harvest availability and whether drying or storage problems are affecting saleable lots.
This distinction changes the investment brief. A tree-planting proposal cannot be assumed to fix drying problems. Better storage cannot restore eroded land. The team must establish which problem exists before selecting the response.
CCC’s guide to finding nature-based solutions in your supply chain explains where to look. Here, the next task is to turn a broad concern into a testable proposal.
2. Develop nature-based carbon investments around the actual supply chain
The assessment would trace Moonbucks’ purchases back through the exporter and supplying producer groups. Which farms supply the contracted lots? Who controls land-management decisions? How long does the buyer expect to maintain the purchasing relationship?
Furthermore, Jimma natural Grade 4 cannot be treated as interchangeable with every Ethiopian coffee. Moonbucks would need to test any substitute against its own blend and quality requirements.
Suppose Moonbucks’ assessment identifies an opportunity to maintain shade trees and restore vegetation along exposed streambanks. The IPCC describes agroforestry as a way to store carbon in vegetation and soil, with potential benefits for erosion control and water quality.1 Moonbucks would need local advice on species, growing conditions and maintenance before deciding how these measures fit its sourcing plan.
The proposal now has a defined sourcing connection and a candidate intervention. The next steps are to test its effect on production, assess carbon eligibility and build the financial case.
3. Compare the proposal with other ways to protect supply
WBCSD’s Nature-based Solutions Blueprint recommends comparing nature-based options with other responses across their benefits and costs.2 For Moonbucks, that means evaluating the landscape proposal alongside drying improvements, storage controls and alternative sourcing arrangements.
The product’s natural-process designation matters. Moonbucks should examine the drying and dry-milling chain alongside land conditions. Its team would check storage practices, contamination risks and incoming-lot quality to see whether problems arise before or after the coffee leaves the farms.
The revised proposal might combine land stewardship with separate post-harvest controls. Each component needs its own purpose and budget. A sustainability label should not obscure which activity is expected to solve which problem.
The project develops as the evidence improves. Its scope should follow the diagnosis rather than preserve the first idea unchanged.
4. Establish what the carbon outcome could count toward
Moonbucks’ sustainability team now tests the proposed carbon case separately from the sourcing case. Is the objective a measurable change in Moonbucks’ value-chain emissions, verified credits for separate voluntary use, or distinct outcomes under carefully defined arrangements?
Scope 3 covers value-chain emissions. A purchasing relationship alone does not prove that a farm intervention can be included in Moonbucks’ inventory. The team needs an applicable accounting method, defensible boundaries and evidence supporting attribution.
SBTi’s FLAG Guidance (forest, land and agriculture), version 1.2, says purchased credits used as offsets cannot meet near-term FLAG or energy and industry targets. Eligible land-based removals are subject to accounting requirements.3 Moonbucks needs to test its proposal against those rules before including an outcome in its targets.
For Moonbucks’ Jimma proposal, maintaining existing trees and establishing new vegetation could involve different carbon questions. Specialists must examine the baseline and additionality, meaning what changes because the project proceeds. They must also assess measurement and the risk that stored carbon is lost. CCC’s MRV and additionality article introduces those tests.
Until that work is complete, Moonbucks should not budget an assumed Scope 3 reduction or credit-sale receipt. Direct emissions reductions remain the priority.
5. Build a financial case that survives weaker assumptions
Moonbucks’ finance team would now build a multi-year budget. UNEP’s State of Finance for Nature 2023 compares current finance with the investment needed to meet climate, biodiversity and land-restoration goals.4 The company would cost its proposed activities, farmer participation and ongoing monitoring. Verification, where required, is a separate expense. Maintenance and responsibility for replacing failed plantings must remain visible after the initial establishment budget ends.
Operational benefits need equally careful treatment. If fewer rejected lots reduce emergency purchasing, count that saving once. Do not add “supply resilience” as another financial benefit when it represents the same avoided cost.
Moonbucks should compare a base case with slower benefits, higher implementation costs and no carbon revenue. It should also distinguish production outcomes from quality and shipment outcomes. A single good harvest would not prove that the landscape intervention caused better delivery performance.
A project can remain worth funding even when its carbon case needs more work. That decision must rest on the operational evidence and the company’s objectives, without unsupported environmental claims.
6. Fund a pilot with a clear expansion decision
Moonbucks’ first approval would fund a bounded pilot, rather than commit the entire sourcing program. Before spending, Moonbucks would agree on participating farms, responsibilities and the evidence needed at review.
Its scorecard could track farmer participation, implementation costs and plant survival, alongside accepted coffee volumes and lot-quality results. Carbon measurements would follow the selected method. Farm-level traceability must connect the intervention to the actual sourcing relationship.
Suppose Moonbucks’ review later finds that storage changes explain most quality improvements, while the land measures need longer observation. Those findings would shape the next decision: expand the proven component, adjust the landscape work or pause further spending. They would not justify crediting all improvements to tree planting.
This gives nature-based carbon investments a practical place in a multi-year strategy. Funding increases as the evidence supports it, and the project can change direction before a larger commitment.
