Reliance Industries Ltd (RIL) has proposed an investment of around ₹2.73 lakh crore over 30 years to develop what could become India’s first integrated Underground Coal Gasification (UCG) complex in Andhra Pradesh’s Eluru district. The proposal involves using deep coal reserves in the Chintalapudi and Recherla blocks to produce synthetic gas, or syngas, which can then be used as an industrial feedstock.
The project is still at a preliminary stage and is contingent on exploration establishing the commercial viability of the coal reserves and the UCG technology. RIL has proposed an initial ₹3,000 crore exploration and pilot phase, after which larger investments would be made if the project proves commercially viable. The scale of the proposed investment makes it one of the largest industrial projects currently being considered in Andhra Pradesh.
RIL Plans ₹2.73 Lakh Crore UCG Project
RIL has submitted a proposal to the Andhra Pradesh government for an integrated underground coal gasification complex in Eluru district.
Unlike conventional coal mining, UCG converts coal into gas while it remains underground. The process involves injecting air, oxygen or another gasification agent into an underground coal seam and converting the coal into syngas.
Project At A Glance
| Parameter | Details |
|---|---|
| Company | Reliance Industries Ltd |
| Location | Eluru district, Andhra Pradesh |
| Proposed investment | ₹2.73 lakh crore |
| Investment period | 30 years |
| Initial exploration/pilot investment | ₹3,000 crore |

The ₹2.73 lakh crore figure represents the proposed investment over the entire 30-year project period, rather than an immediate capital expenditure commitment.
How Underground Coal Gasification Works
UCG differs from conventional mining because the coal does not need to be brought to the surface before being converted into gas.
Instead, wells are drilled into the coal seam. Gasification agents are introduced underground, triggering chemical reactions that convert coal into syngas.

The resulting syngas can contain gases such as hydrogen, carbon monoxide, methane and carbon dioxide. Its eventual use depends on how the gas is processed and the economics of the project.
₹3,000 Crore Exploration Phase Comes First
RIL’s proposal is structured in stages rather than requiring the entire ₹2.73 lakh crore to be invested immediately.
The first phase involves approximately ₹3,000 crore for exploration and pilot testing. The objective will be to determine whether the deep coal resources can be economically converted into syngas using UCG technology.
Proposed Investment Roadmap
| Phase | Focus | Proposed Investment |
|---|---|---|
| Phase 1 | Exploration and pilot testing | ₹3,000 crore |
| Phase 2 | Development | Subject to viability |
| Phase 3 | Production and integrated complex | Part of ₹2.73 lakh crore |
| Overall project period | Long-term development | ₹2.73 lakh crore / 30 years |
This phased approach reduces the risk of committing the entire investment before the geological and technological feasibility of the project is established.
Deep Coal Reserves Are At The Centre Of The Project
The proposed complex will focus on coal resources in the Chintalapudi and Recherla blocks in Andhra Pradesh.
Reports indicate that the targeted coal seams are located deep underground, making conventional mining more difficult and potentially providing a case for UCG technology.
Why Deep Coal Matters
| Conventional Mining Challenge | Potential UCG Advantage |
|---|---|
| Very deep coal seams | Coal can be gasified underground |
| Large surface infrastructure | Reduced need for conventional extraction |
| Mining and transportation | Gas can be brought to the surface |
| Difficult extraction economics | Technology may unlock otherwise challenging resources |
However, these potential advantages depend heavily on geological conditions and the ability to control the underground gasification process.
What Is Syngas And Why Does It Matter?
Syngas, short for synthetic gas, is a mixture of gases produced when carbon-based materials such as coal undergo gasification.
It can serve as an intermediate feedstock for several industrial applications.

Industrial Products
Depending on the final configuration, syngas can potentially be used to produce chemicals, fuels, hydrogen and other industrial products.
For RIL, the project could therefore create a domestic feedstock source for parts of its large energy and chemicals businesses.
The Project Could Support India’s Import-Reduction Strategy
One of the potential strategic benefits is the ability to convert domestic coal resources into useful industrial feedstock.
India imports significant quantities of hydrocarbons and chemical feedstocks. Producing syngas domestically could potentially reduce some import dependence if the resulting economics are competitive.
The project therefore sits at the intersection of India’s domestic-resource strategy and its effort to develop more local industrial value chains.
Potential Strategic Benefits
| Area | Potential Impact |
|---|---|
| Domestic coal utilisation | Unlocks deep coal resources |
| Syngas production | Creates domestic industrial feedstock |
| Import substitution | Could reduce selected feedstock imports |
| Chemicals | Potential downstream applications |
| Energy security | Diversifies domestic resource utilisation |
| Industrial development | Supports a large integrated complex |
| Regional investment | Could create jobs and infrastructure |
The actual import-substitution benefit, however, cannot be determined until the project’s production capacity and economics are established.
RIL’s Proposed Investment Is Massive In Scale
The ₹2.73 lakh crore proposal is equivalent to approximately ₹2.73 trillion.
That makes the project substantially larger than the initial ₹3,000 crore exploration programme.

The ₹2.73 lakh crore figure is a long-term proposal; the ₹3,000 crore figure is the initial exploration and pilot phase.
The comparison highlights how much larger the potential development phase would be if the initial exploration establishes commercial viability.
Project Could Create Thousands Of Jobs
The proposed complex could also have a significant economic impact on the Eluru region.
Reports indicate the project could create up to 5,000 direct jobs and as many as 35,000 indirect and induced livelihoods if it reaches full development.
Potential Employment Impact
| Employment Category | Potential Jobs / Livelihoods |
|---|---|
| Direct employment | Up to 5,000 |
| Indirect + induced livelihoods | Up to 35,000 |
| Potential total impact | Up to 40,000 |
These figures represent potential employment associated with the project and should not be treated as guaranteed jobs at the current proposal stage.
Why Andhra Pradesh Could Benefit
A project of this scale could generate demand across several parts of the regional economy.
Construction, engineering, equipment manufacturing, transportation, utilities and supporting services could all benefit if the project progresses.

The project’s long 30-year investment horizon could also create opportunities for ancillary industries around the gasification complex.
Commercial Viability Is The Biggest Question
Despite the headline investment figure, RIL has not committed the entire ₹2.73 lakh crore at this stage.
The project depends on exploration and pilot testing demonstrating commercial viability.
Several factors will determine whether UCG can become economically attractive in the targeted coal blocks.
Key Viability Factors
| Factor | Why It Matters |
|---|---|
| Coal seam quality | Determines gas output |
| Depth and geology | Affects technical feasibility |
| Gasification efficiency | Determines production economics |
| Syngas quality | Determines downstream applications |
| Water requirements | Important for operations |
| Environmental controls | Determines regulatory feasibility |
| Capital cost | Influences project returns |
| Gas prices | Determines competitiveness |
| Downstream demand | Supports project economics |
The exploration phase will therefore be crucial before RIL moves toward the larger investment stages.
Environmental Concerns Will Need Attention
Underground coal gasification is often presented as an alternative to conventional coal extraction, but it is not free of environmental risks.
Potential concerns include groundwater contamination, subsurface control, carbon emissions and management of underground gasification zones.
The environmental performance of the proposed Andhra project will therefore depend on the specific geology, technology and monitoring systems adopted.
Environmental Questions
| Issue | Key Question |
|---|---|
| Groundwater | Can contamination be prevented? |
| Carbon emissions | How much CO₂ will the process generate? |
| Underground control | Can gasification remain within the intended zone? |
| Land impact | How much surface infrastructure is required? |
| Water | What will be the project’s water demand? |
| Monitoring | How will underground conditions be tracked? |
The project’s commercial viability and regulatory approvals will need to address these issues before full-scale development.
RIL Could Build An Integrated Value Chain
The word integrated in the proposal is significant.
Rather than simply producing syngas, an integrated complex could connect the gasification operation with downstream chemical, fuel or industrial production.

Such integration could potentially improve economics by allowing RIL to capture value across multiple stages of the production chain.
The exact downstream configuration, however, remains dependent on the project’s development plans.
RIL’s Move Expands Its Energy And Materials Footprint
Reliance has historically operated across oil refining and petrochemicals, while in recent years it has also invested heavily in new energy, digital infrastructure, retail and other businesses.
The proposed UCG complex would add another large-scale industrial project to its energy and materials portfolio.
The project could also complement RIL’s existing capabilities in gas processing and chemicals, although the exact integration with its existing operations has not yet been disclosed.
India’s Coal Strategy Is Evolving
The proposed project comes at a time when India continues to rely heavily on coal for its energy needs while also pursuing renewable-energy expansion.
Coal remains an important domestic resource because it provides energy security and supports industrial activity. Technologies such as gasification are being explored as ways to extract additional value from coal beyond direct combustion.
Traditional Coal Vs Gasification
| Conventional Coal | Coal Gasification |
|---|---|
| Coal extracted | Coal converted into gas |
| Burned directly | Syngas used as feedstock |
| Primarily energy use | Energy + chemical applications |
| Requires mining | UCG can gasify underground |
| Transport coal | Potentially transport/process gas |
The UCG model is therefore less about eliminating coal use and more about converting coal into a different form that can potentially be used across industrial applications.
Reliance Industries Stock Reacts To The Proposal
RIL shares gained around 0.45% to ₹1,313.35 in early trading after reports of the proposed project emerged, according to Business Standard.
The relatively modest stock reaction suggests that investors may be treating the project as a long-term strategic proposal rather than immediately assigning the entire ₹2.73 lakh crore investment to RIL’s valuation.
Market Reaction
| Metric | Figure |
|---|---|
| RIL share price cited | ₹1,313.35 |
| Early-session move | +0.45% |
| Proposed project investment | ₹2.73 lakh crore |
| Project horizon | 30 years |
This distinction is important because the proposed investment is spread across three decades and remains contingent on commercial viability.
What Investors Should Watch
For RIL investors, the most important developments will be the results of exploration and pilot testing rather than the headline investment number.
The company will need to establish that the coal blocks can produce syngas at commercially competitive costs.

The Bigger Picture
Reliance Industries’ proposed ₹2.73 lakh crore, 30-year investment in an integrated Underground Coal Gasification complex could become a major industrial project for Andhra Pradesh and potentially a landmark development for India’s coal-gasification sector. The project would target deep coal reserves in the Chintalapudi and Recherla blocks and convert them into syngas for potential industrial applications.
However, the headline investment should not be interpreted as an immediate ₹2.73 lakh crore commitment. RIL’s first step is a ₹3,000 crore exploration and pilot programme, and the larger development depends on proving the technology and coal resources commercially viable. Environmental, geological, regulatory and downstream-demand factors will all determine whether the proposed complex moves from an ambitious plan to a large-scale operating project.
Looking Ahead
The next major milestone will be the exploration and pilot phase in Andhra Pradesh. RIL will need to establish the quality and accessibility of the targeted coal resources while demonstrating that underground gasification can be operated safely and economically. Only after those tests will the company be in a position to make larger investment decisions.
If successful, the project could create a new domestic pathway for converting difficult-to-mine coal into syngas and potentially supporting chemicals, fuels and other industrial applications. For Andhra Pradesh, the project could bring substantial long-term investment and employment, while for RIL it could create another large industrial platform. The scale of the proposal is significant, but its ultimate impact will depend on whether the first ₹3,000 crore phase proves the commercial case for the much larger ₹2.73 lakh crore vision
