Introduction: Machkund & India's Inter-State Hydropower Landscape
📖 Introduction — Machkund Hydroelectric Fire & Inter-State Energy Governance
What Is the Machkund Hydroelectric Project?
The Machkund Hydroelectric Project is a 120 MW inter-state hydropower facility jointly owned and operated by the governments of Andhra Pradesh and Odisha. Located at the foot of the Eastern Ghats near the celebrated Duduma Falls in Koraput district, Odisha, the project harnesses the flow of the Machkund River — locally called the Sileru — which is a tributary of the Sabari River, itself part of the Godavari basin (India's second longest river). With six turbine units commissioned in 1955, this project is not merely a power station — it is a symbol of post-independence cooperative federalism, inaugurated by India's first President, Dr. Rajendra Prasad, and built on an agreement dating to 1945.
The fire of 24 May 2026, caused by a suspected short circuit in the turbine room, which damaged two turbines and may disrupt power generation for up to six months, forces a reckoning with two intersecting policy failures that UPSC examiners find analytically rich: the structural vulnerability of ageing inter-state energy infrastructure and the governance gap in disaster response when jurisdiction is shared between states.
Why This Matters: India's Hydropower Dependence & the 500 GW Target
Hydropower is India's most important source of dispatchable renewable energy — unlike solar or wind, it can be ramped up within minutes to meet peak demand and stabilise the grid. As of March 2026, India's total installed power capacity stands at 533 GW, with large hydro contributing 51.41 GW and small hydro 5.17 GW. The country reached the milestone of 50% non-fossil installed capacity in June 2025, five years ahead of its NDC target. The government's Small Hydro Power Development Scheme (2026–31), approved with an outlay of ₹2,584.60 crore, aims to add 1,500 MW of new small hydro capacity by 2031.
Yet even as India adds new capacity, it has consistently neglected the safety and operational resilience of its legacy hydro assets — many commissioned in the 1950s–70s. Machkund, at 70+ years of age, is emblematic of this neglect. India has identified a total hydroelectric potential of 1,45,320 MW, of which only about 32% has been harnessed; but the infrastructure already in place is deteriorating faster than it is being upgraded.
🔥 Ageing Infrastructure Problem
- Many Indian hydro plants are 50–70 years old
- Turbine rooms using mid-20th century electrical systems
- Renovation and Modernisation (R&M) funds often disputed between co-owning states
- Remote locations hinder rapid emergency response
- No unified inter-state disaster protocol for energy infrastructure
🏛 Inter-State Governance Complexity
- Joint ownership means shared liability — often nobody acts first
- 70:30 (AP:Odisha) power ratio changed to 50:50 only in 2020
- Electricity Act 2003 and State Electricity Boards operate independently
- NDMA guidelines do not specifically address inter-state energy facility disasters
- Fire services are a State subject (12th Schedule), complicating joint response
📌 Scale in Context
India's total large hydro capacity of 51.41 GW (March 2026) provides critical grid-balancing services that no other renewable source can replicate. A single inter-state project failure ripples across two state grids simultaneously — with no pre-defined crisis management ownership.
Analytical Takeaway: The Machkund fire is not merely an industrial accident — it is a governance stress-test that reveals the fault lines of India's cooperative federalism in energy infrastructure: shared ownership without shared safety protocols, ageing assets without mandatory renewal timelines, and disaster management frameworks that treat state borders as real barriers in an emergency.

The Machkund Project: History, Geography & Inter-State Architecture
Historical Origin: From a Princely Vision to Post-Independence Symbol
The genesis of the Machkund Hydroelectric Project lies in an unlikely place: the vision of Maharaja Vikram Dev Varma of Jeypore, who in the 1920s proposed harnessing the Machkund River's considerable fall to electrify his villages. This early vision anticipated what would become one of India's earliest and most significant inter-state cooperative energy projects. The Inter-State Agreement formalising the project was signed on 14 January 1945, with the power and cost to be shared in a 70:30 ratio (Andhra Pradesh : Odisha) — a ratio that reflected the relative population and industrial needs of the day.
Construction commenced in 1948, one year after Independence, and the project entered commercial operation in 1955. Its formal inauguration by Dr. Rajendra Prasad, India's first President, bestowed on it a stature beyond mere infrastructure — it represented the early federal promise of shared development. In October 2020, a revised agreement between AP and Odisha changed the cost and benefit-sharing ratio to 50:50 for Renovation, Modernisation, and Upgradation (R, M & U) works, reflecting Odisha's growing energy needs over seven decades.

Geography: The Machkund/Sileru River & the Godavari Basin
The Machkund River is a significant left-bank tributary of the Sabari River (also called Sileru), which in turn joins the Godavari — India's Dakshina Ganga and its second-longest river at approximately 1,465 km. The Machkund rises in the Mudugal Hills of what is now Alluri Sitharama Raju district, Andhra Pradesh, and flows northward through the high-altitude Eastern Ghats plateau, forming the state boundary between AP and Odisha. Its dramatic 157-metre drop over the Duduma Falls — one of the tallest waterfalls in peninsular India — is the geographic engine of the power project.
The project infrastructure consists of: (a) the Jalaput Dam — an earth-fill dam of 60.65 m height and 419 m length, impounding 34 TMCft gross capacity in the Jalaput Reservoir (surface area: 97.12 sq km); (b) a diversion dam, 17 km downstream of Jalaput, to channel water into the power canal; and (c) the powerhouse with 6 turbine units (3 × 17 MW + 3 × 23 MW = 120 MW installed capacity), operated by APGENCO (Andhra Pradesh Power Generation Corporation) with OHPC holding Odisha's stake.

✅ River System Note
The Sileru/Machkund river flows through the tri-junction of Andhra Pradesh, Chhattisgarh, and Odisha before joining the Sabari and ultimately the Godavari. This hydrological geography makes it simultaneously a boundary marker, a biodiversity corridor, and a contested resource — making any disaster on this river system instantly a multi-state concern.
Analytical Takeaway: The Machkund project's 70-year history illustrates how cooperative federalism in energy was built on colonial-era agreements and has since evolved through renegotiation (1945 → 2020) — but without ever establishing a unified safety and disaster response framework commensurate with the infrastructure's shared risk.

Structural, Governance & Safety Vulnerabilities
⚡ Issues — Inter-State Energy Infrastructure & Disaster Management Failures
Issue 1: Ageing Infrastructure with Deferred Modernisation
At over 70 years of operation, the Machkund project's turbines, electrical systems, and turbine room infrastructure date to mid-20th century design standards. The suspected short circuit in the turbine room that triggered the May 2026 fire is a symptom of a broader crisis: India's legacy hydropower assets have received inadequate Renovation, Modernisation, and Upgradation (R, M & U) investment. In the case of joint inter-state projects, R&M works are complicated by the need for bilateral agreement, cost-sharing negotiations, and joint approvals — all of which create delays. The revised 50:50 cost-sharing agreement of October 2020 was itself a belated recognition of the need for shared investment, but structural upgrades on ageing electrical systems have not kept pace with the risk.
🔍 Critical Analysis: The Deferred Maintenance Trap
Joint infrastructure projects fall into a structural governance trap where both owners expect the other to bear the burden of maintenance. When cost ratios are unequal (as the original 70:30 split), the minority stakeholder often resists large capital expenditure. Even after the 2020 equalisation, the political and bureaucratic cycles of two state governments must align before a major R&M project can be approved and funded. This creates windows of structural risk that can last years or even decades — during which ageing equipment operates without proper safety upgrades.
Issue 2: The Inter-State Command Vacuum in Emergency Response
When the fire broke out, fire and emergency services — classified as a State subject under the 12th Schedule of the Constitution — were dispatched from Koraput, Odisha. But the project is jointly managed by APGENCO (an AP body) and OHPC (an Odisha body). This dual administrative ownership means there is no single Incident Commander with authority to direct the combined resource of both states' emergency services. The Srisailam hydroelectric plant fire of August 2020 — which killed nine workers including five engineers in Telangana — had already demonstrated the catastrophic cost of poor emergency preparedness at underground hydroelectric plants. The Machkund fire reveals that lessons from Srisailam have not been institutionalised into inter-state project safety protocols.
Issue 3: Remote Location and Response Lag
The Machkund powerhouse is located approximately 92 km from Koraput and 176 km from Visakhapatnam — the nearest major cities on either state side. This remoteness means that specialised fire-fighting equipment for an industrial electrical fire, and medical support for burn injuries, can take considerable time to reach the site. The Disaster Management Amendment Act 2025 mandates mandatory safety drills twice a year and disaster audits for infrastructure projects, but implementation in remote tribal districts remains weak due to administrative capacity constraints and jurisdictional ambiguity between APGENCO and OHPC.
Issue 4: Absence of a Critical Energy Infrastructure Protection (CEIP) Framework
India does not have a dedicated Critical Energy Infrastructure Protection (CEIP) framework comparable to those in the United States (Energy Policy Act), the EU (European Programme for Critical Infrastructure Protection), or China's grid security protocols. The National Electricity Plan 2023–32 and the Electricity Act 2003 focus primarily on capacity addition and power procurement — not on the safety, resilience, and disaster management of existing assets. NDMA guidelines on fire safety cover industrial and urban establishments but do not specifically address the unique hazards of underground turbine rooms, high-voltage equipment fires, and inter-state command in jointly managed hydropower facilities.
🔍 Critical Analysis: Federal Fault Line in Fire Services
Fire services in India are a State subject. In a joint project spanning two states, the question "whose fire brigade responds first?" sounds simple but is legally and administratively complex. APGENCO's jurisdiction is in AP; OHPC's is in Odisha. The plant is in Odisha — so Odisha's fire services responded. But the primary technical operator (APGENCO) is an AP body. This disjunction between operational control and territorial emergency response is a constitutional design gap that the Disaster Management Amendment Act 2025, despite its improvements, has not fully resolved for jointly owned infrastructure.
⚠ Mains Answer Trap
Do not frame the Machkund issue as simply an "industrial accident" or a "maintenance failure." The analytically richer framing for Mains is: it is a cooperative federalism failure — where shared ownership without shared safety governance creates systemic risk. Always connect infrastructure disasters to the federal structure and the constitutional division of powers.
Analytical Takeaway: The Machkund fire reveals four overlapping failures: deferred modernisation of ageing assets, the inter-state command vacuum in emergencies, remote-location response lag, and the absence of a dedicated Critical Energy Infrastructure Protection framework — all of which are structurally embedded in India's federal arrangement around jointly owned infrastructure.

Ecological & Environmental Dimensions of the Machkund Region
The Eastern Ghats: A Biodiversity Hotspot Under Pressure
The Machkund project is embedded within the Eastern Ghats — a discontinuous range of hills running from Odisha through Andhra Pradesh and into Tamil Nadu, recognised as one of India's richest biodiversity zones. The Koraput district of Odisha, where the project is located, sits in a transitional ecological zone between the Eastern Ghats highlands and the Godavari plains — characterised by tropical semi-evergreen forests, sal and teak-dominated deciduous forests, and a remarkable diversity of endemic flora. The Eastern Ghats Biodiversity Strategy acknowledges that hydroelectric projects including Machkund have submerged considerable portions of forest, and that settlements around these projects drive further exploitation of surrounding woodland.
The Koraput–Kolab–Duduma landscape is one of the last refuges of several endemic and endangered species in peninsular India. The hill streams of the Sabari/Sileru river system — studied for freshwater fish diversity — host at least 36 species of freshwater fish across 24 genera, including endemic cyprinids that are vulnerable to changes in water temperature, flow, and chemical composition. An industrial fire involving electrical oils, transformer fluids, and burning plastics introduces the risk of chemical runoff into the Machkund/Sileru river — a concern that must be factored into the post-incident environmental audit.
Tribal Communities: The Invisible Stakeholders
The hills surrounding the Machkund project and Duduma Falls are home to the Bonda, Gadaba, and Paraja tribes — among the most geographically isolated and anthropologically distinct tribal communities in India. The Bondas of the Malkangiri–Koraput plateau are classified as a Particularly Vulnerable Tribal Group (PVTG). Their livelihoods, cultural practices, and food security are deeply tied to the forests and streams of the Eastern Ghats. The Machkund reservoir (Jalaput) has historically displaced communities and submerged forests — a displacement whose full social and ecological cost has never been comprehensively assessed. Any prolonged outage, fire-related chemical contamination of the river, or expanded industrial activity for reconstruction work would compound this already fragile situation.
The Reservoir, Duduma Falls & Downstream Ecology
The Jalaput Reservoir (surface area: 97.12 sq km) is not merely a storage body — it is an altered riparian ecosystem that now supports its own aquatic food web, influenced by sedimentation, thermal stratification, and variable water levels. The Duduma Falls (157 m, one of the tallest in peninsular India) — fed by the Machkund's regulated flow — is a critical ecological node: the waterfall's mist creates a unique microclimate that sustains rare mosses, ferns, and amphibian communities on surrounding rocks. Disrupted water flow due to turbine outage, or contamination from fire suppression chemicals, could temporarily alter the falls' ecology. More critically, the Sabari River downstream — which forms the Telangana–AP border and supports significant agricultural activity — would be affected by any contamination event that traverses the Machkund–Sileru–Sabari–Godavari chain.

✍ Mains Tip
For GS-III (Environment) answers on hydropower and disasters, always bring in the ecosystem services angle: the Machkund region provides provisioning (fisheries, water), regulating (flood moderation, water purification), and cultural (tribal, pilgrimage) services that industrial accidents can damage. Quantify where possible — 36 freshwater fish species, PVTG communities, 97 sq km reservoir ecosystem — to show evidence-based reasoning.
🔍 Critical Analysis: Legacy Environmental Deficit of Inter-State Hydro Projects
Projects like Machkund were built before India's environmental regulatory framework existed (the Environment Protection Act came in 1986, EIA notification in 1994). They carry a legacy environmental deficit — submerged forests, displaced communities, and altered river ecologies — for which no retrospective environmental liability or ecological restoration plan exists. When such projects also become disaster sites, the compound ecological impact (construction-era damage + operational-era alteration + disaster contamination) must be assessed as a whole-system problem, not just an incident-response question.
Analytical Takeaway: The Machkund fire's ecological significance extends far beyond the turbine room — it threatens the biodiversity of the Eastern Ghats, the river ecology of the Sabari–Godavari chain, the livelihoods of PVTG tribal communities, and the downstream agricultural systems across three states — a cascade of impacts invisible in conventional energy-sector disaster assessments.

Energy Security, Federal & Disaster Governance Implications
🔗 Implications — For India's Energy System, Federal Structure & Disaster Architecture
Implication 1: Immediate Energy Security Impact on AP and Odisha
The outage of the Machkund project's full 120 MW capacity — or at minimum the two damaged turbines — for an estimated six months has direct grid consequences for both Andhra Pradesh and Odisha. While 120 MW may appear modest against India's 533 GW installed base, at the state grid level it represents a meaningful fraction of firm, dispatchable renewable capacity. Odisha's per-capita electricity consumption remains below the national average, and its grid is heavily reliant on its hydro fleet (Hirakud, Balimela, Rengali, Upper Indravati, and Machkund). For Andhra Pradesh, APGENCO manages a diverse generation portfolio, but the loss of reliable peaking power from Machkund — particularly during monsoon season when hydro output is highest — creates a dispatching challenge.
Implication 2: A Stress-Test for India's Cooperative Federalism in Energy
The post-fire situation will immediately raise questions that go to the heart of cooperative federalism in energy: Who bears the reconstruction cost? What is the liability for the four workers with burn injuries — APGENCO, OHPC, or both? Which state's labour laws apply? Who controls the site investigation? Under the Electricity Act 2003, the Central Electricity Authority (CEA) has technical oversight of generation schemes, but regulatory jurisdiction for state-owned generation assets lies with the respective State Electricity Regulatory Commissions (SERCs) — in this case, the APERC and the OERC. Neither has a joint or concurrent authority over the Machkund plant as an inter-state entity. This jurisdictional ambiguity will slow every phase of the disaster response — from immediate investigation to long-term reconstruction financing.
🔍 Critical Analysis: Federal Fragmentation as an Energy Risk
India's energy federalism assigns generation to states but keeps transmission and grid operation under central oversight (PGCIL, POSOCO). For jointly owned generation assets, this creates a structural anomaly: the asset is sub-national, but its failure has supra-state consequences. The Inter-State River Water Disputes Act addresses water — not the power plants on those rivers. The absence of a Joint Inter-State Infrastructure Regulatory Authority for assets like Machkund means that every decision — safety upgrades, emergency response, reconstruction costs, environmental liability — must be negotiated bilaterally, with the attendant delays that political cycles between two different state governments inevitably produce.
Implication 3: Shadow on India's 500 GW Non-Fossil Target
India achieved 51.93% non-fossil installed capacity as of March 2026 — surpassing its NDC milestone five years early. Large hydro (51.41 GW) is central to this achievement, providing the grid-balancing backbone that allows large volumes of intermittent solar and wind capacity to be absorbed reliably. If legacy hydro plants like Machkund are not systematically upgraded for fire safety and structural resilience, the risk of cascading outages across India's ageing hydro fleet could undermine the very grid stability on which the renewable energy expansion depends. The Machkund fire is thus not an isolated event — it is a signal about the systemic vulnerability of India's legacy hydro asset base at a moment when the grid most needs its reliability.
Implication 4: The Disaster Management Accountability Gap
The Disaster Management (Amendment) Act 2025 — which came into force on 9 April 2025 — introduced mandatory disaster audits for infrastructure projects, annual updates to State Disaster Management Plans, and Disaster Management Training Units for civil servants and first responders. However, critics have noted that the Act strengthens centralised and top-down mechanisms without sufficient provisions for the specific challenges of inter-state infrastructure disasters. When an industrial fire occurs in a remote tribal district on a state border, managed by two state-owned corporations, the chain of command runs: District Disaster Management Authority (DDMA, Koraput) → Odisha SDMA → NDMA. AP's emergency machinery is structurally excluded from this chain even though it co-owns the facility. This is not a failure of individuals — it is a failure of institutional design.

Analytical Takeaway: The Machkund fire's implications span four dimensions: immediate grid supply disruption for both states; a federalism stress-test exposing the jurisdictional vacuum in jointly owned infrastructure; a systemic warning for India's legacy hydro fleet at a critical juncture for its renewable energy programme; and a concrete demonstration of the Disaster Management Act 2025's residual institutional gap for inter-state industrial disasters.

Constitutional & Legal Framework Governing Inter-State Hydropower Disasters
Constitutional Architecture: Water, Power, and Disaster
The constitutional division of powers creates overlapping and sometimes conflicting jurisdictions for a project like Machkund. Entry 17, State List (7th Schedule) grants states authority over water supply, irrigation, canals, and hydropower. However, Entry 56, Union List empowers Parliament to regulate and develop inter-state rivers and river valleys in public interest — the constitutional hook for central intervention. Article 262 further allows Parliament to bar courts from adjudicating inter-state water disputes, channelling them to tribunals instead. The net effect is that water and the power generated from it sits in a constitutional grey zone — predominantly State jurisdiction, but subject to Union regulation when the resource crosses state lines.
Fire services, meanwhile, are a State subject and listed in the 12th Schedule (municipal functions). Disaster management overall is governed by the Disaster Management Act, 2005 — a Central legislation operative through NDMA (headed by the Prime Minister) → SDMA (headed by Chief Minister) → DDMA (headed by District Collector). There is no mechanism in the DMA framework specifically for inter-state infrastructure disasters where both states have co-ownership of the disaster site.
Constitutional & Legal Framework — Inter-State Hydropower & Disaster Management
| Provision | Key Content | Relevance to Machkund |
|---|
| Entry 17, State List | Water, irrigation, hydropower — State domain | AP and Odisha both claim jurisdictional authority over their shares of Machkund |
| Entry 56, Union List | Parliament can regulate inter-state rivers in public interest | Central basis to intervene in Machkund's operational/safety standards |
| Article 262 | Adjudication of inter-state water disputes; bars court jurisdiction | Water-sharing aspect of Machkund governed by 1945/2020 inter-state agreements |
| ISRWDA 1956 | Inter-State River Water Disputes Act — tribunal mechanism | Broader Godavari and Vamsadhara disputes involving AP & Odisha as context |
| Electricity Act 2003 | CEA technical oversight; SERCs regulate state generation | Dual SERC (APERC + OERC) jurisdiction with no joint authority for Machkund |
| DMA 2005 | NDMA, SDMA, DDMA hierarchy; response framework | Koraput DDMA leads on-ground response — AP SDMA structurally excluded |
| DM Amendment Act 2025 | Disaster audits for infrastructure; UDMA; strengthened NDMA autonomy; mandatory drills twice/year | Applies in principle to Machkund but no inter-state industrial disaster protocol created |
| 12th Schedule | Fire services — municipal/state subject | Odisha fire services respond; AP fire services have no automatic mandate on Odisha soil |
⚖ Precedent: Srisailam Hydroelectric Plant Fire — August 2020
A fire in the underground powerhouse of the Srisailam dam (Telangana–Andhra Pradesh border project) killed 9 workers including 5 engineers on 20 August 2020. The fire began from an electrical short circuit at the left bank powerhouse. Though Srisailam is primarily a Telangana project, the incident led to calls for mandatory fire safety audits for all underground and enclosed turbine rooms across India. Five years later, a comparable turbine-room fire at Machkund reveals that no systematic national-level safety upgradation of such facilities has been mandated or implemented.
The Disaster Management Amendment Act 2025: What It Does and What It Misses
The Disaster Management (Amendment) Act, 2025 received Presidential assent on 29 March 2025 and came into force on 9 April 2025. Its key additions relevant to energy infrastructure include: mandatory disaster audits for infrastructure projects; Disaster Management Training Units for civil servants and first responders; mandatory safety drills twice a year for schools, hospitals, and industrial units; strengthened NDMA autonomy to directly coordinate with central ministries; and the creation of Urban Disaster Management Authorities (UDMAs) for large cities. However, as critics in the Economic and Political Weekly have noted, the Amendment Act predominantly strengthens the centralised, top-down architecture of the 2005 framework without creating horizontal coordination mechanisms between states for jointly owned inter-state infrastructure. This is the precise gap the Machkund fire exposes.
🌱 Constitutional Reform Suggestion
A Joint Disaster Management Protocol (JDMP) — modelled on inter-state police cooperation agreements — could be formalised under Article 263 (Inter-State Council) for all nationally critical infrastructure jointly owned by two or more states. Such a protocol would pre-define incident command, cost-sharing for emergency response, joint investigation mechanisms, and environmental liability for inter-state projects, overriding the current situation where every inter-state industrial disaster requires ad hoc bilateral negotiation under crisis conditions.
Analytical Takeaway: India's constitutional and legal framework for inter-state energy infrastructure disasters remains a patchwork — with water under Entry 17/56, electricity under the Electricity Act, fire services in the 12th Schedule, and disaster management under the DMA 2005/2025. No single instrument integrates these overlapping authorities for a scenario like Machkund, where all four domains intersect simultaneously in a remote, ecologically sensitive, tribally inhabited inter-state location.

Initiatives, Policy Responses & the Way Forward
🏛 Initiatives — Policy Frameworks & Way Forward
Existing Initiatives: What India Has Done
Several policy initiatives provide the institutional scaffolding within which the Machkund fire response and reconstruction must operate. These include both legacy frameworks and recent policy developments:
- APGENCO–OHPC Revised Agreement (Oct 2020): Changed cost-benefit sharing from 70:30 to 50:50 for R, M & U works — the first formal acknowledgment of shared modernisation responsibility. This agreement is the legal basis for cost-sharing in the fire-damage reconstruction.
- Disaster Management (Amendment) Act 2025 (in force 9 April 2025): Mandates disaster audits for infrastructure projects and mandatory safety drills twice annually for industrial units. Applies directly to Machkund and all jointly owned hydro facilities.
- Small Hydro Power (SHP) Development Scheme 2026–31: Union Cabinet-approved scheme with ₹2,584.60 crore outlay to add 1,500 MW of small hydro (1–25 MW). Prioritises hilly and North-Eastern states. Provides a model for decentralised, resilient energy systems that reduce dependence on large inter-state projects.
- National Electricity Plan 2023–32: Outlines ₹9.15 lakh crore investment in power infrastructure, projected to meet 458 GW peak demand by 2032. Includes provisions for hydro capacity addition but lacks specific R&M mandates for legacy assets.
- Coalition for Disaster Resilient Infrastructure (CDRI): Launched by PM Modi at the UN Climate Action Summit, September 2019; currently with 53 countries and 12 international organisations. CDRI's mandate covers resilient infrastructure against climate-induced and industrial disasters — directly relevant to the Machkund situation. India can leverage CDRI frameworks for developing inter-state hydropower safety standards.
- NDMA Guidelines on Industrial Disasters: NDMA has released guidelines on industrial disaster management, including fire safety. However, these do not specifically address the command-and-control challenges of inter-state industrial facilities.
✅ India's Renewable Energy Position (Context for Hydropower's Importance)
As of 31 March 2026: India's total non-fossil installed capacity = 283.46 GW (target: 500 GW by 2030). Large hydro contributes 51.41 GW of this total — representing ~18% of non-fossil capacity, and critically, nearly all of India's dispatchable renewable capacity. Protecting this legacy fleet is as important as building new capacity. (Source: PIB/Ministry of New & Renewable Energy, April 2026)
What Needs to Be Done: The Way Forward
🌱 Way Forward 1: Mandatory Hydro Asset Safety Audit & R&M Timeline
The Central Electricity Authority (CEA), in consultation with NDMA and state electricity regulators, should mandate a comprehensive safety audit of all hydropower plants over 25 years of age — with specific focus on electrical systems, turbine room fire suppression, and structural integrity of turbine chambers. For inter-state projects, the audit should be jointly conducted and funded, with a time-bound R&M plan (5-year rolling schedule) as a condition of continued generation licence under the Electricity Act 2003.
🌱 Way Forward 2: Joint Disaster Management Protocol for Inter-State Infrastructure
Under Article 263 (Inter-State Council) or through a dedicated amendment to the DMA 2005/2025, India should create a Joint Disaster Management Protocol (JDMP) for all infrastructure assets jointly owned by two or more states. The JDMP should pre-define: a unified Incident Command Structure; automatic cross-state deployment authority for fire and emergency services; joint investigation committees; and a pre-agreed cost-sharing formula for emergency response expenditure.
🌱 Way Forward 3: Critical Energy Infrastructure Protection (CEIP) Framework
India should develop a dedicated Critical Energy Infrastructure Protection (CEIP) policy — analogous to the US Energy Policy Act's critical infrastructure provisions — covering all power plants above 100 MW, all inter-state transmission corridors, and all reservoirs above 50 TMCft capacity. The CEIP framework should specify: minimum fire suppression standards for turbine rooms; mandatory real-time SCADA-based anomaly detection for electrical systems; emergency isolation protocols; and defined response time standards for remote-location incidents.
🌱 Way Forward 4: Ecological & Tribal Impact Assessment Post-Disaster
Every industrial disaster at a hydropower facility in or adjacent to a biodiversity-rich or tribally inhabited area should trigger an automatic Environmental & Social Impact Assessment (ESIA) under the MoEFCC. For Machkund specifically, this should assess: chemical contamination of the Sileru/Sabari river; impact on the 36+ freshwater fish species in the hill streams; air quality monitoring for Bonda, Gadaba, and Paraja tribal settlements; and a forest fire risk assessment for the Eastern Ghats dry deciduous belt surrounding the project.
🌱 Way Forward 5: Leverage CDRI for Inter-State Hydro Resilience Standards
As the founding country of the Coalition for Disaster Resilient Infrastructure (CDRI), India should develop, in collaboration with CDRI's 53 member countries, an International Hydropower Disaster Resilience Standard — covering design, maintenance, emergency response, and environmental liability for legacy hydro assets. This would simultaneously strengthen India's domestic practices and enhance its global soft-power as a leader in infrastructure resilience.
✍ Mains Tip: The Innovation I in 5I
For GS-III Mains answers on energy infrastructure disasters, the Innovation / Way Forward section earns marks when it is specific, institution-linked, and multi-dimensional. Generic suggestions ("improve maintenance," "create awareness") lose marks. Anchor each recommendation in a specific legal provision (Article 263, Electricity Act 2003, DMA 2005), a specific institution (CEA, NDMA, CDRI), and a specific mechanism (JDMP, CEIP, mandatory R&M timeline) — as done above.
Analytical Takeaway: Existing initiatives — from the 2020 AP–Odisha 50:50 agreement to the DMA Amendment 2025 to the CDRI — provide the building blocks for a robust response, but none individually addresses the full complexity of inter-state industrial disaster governance. The Way Forward requires a systems upgrade: not one new law, but an integrated package of safety mandates, federal coordination mechanisms, ecological protection protocols, and international standards — all anchored in India's existing constitutional framework.

📊 Current Affairs — PIB / Ministry of Jal Shakti · April 2025
The Disaster Management (Amendment) Act, 2025 received Presidential assent on 29 March 2025 and came into force on 9 April 2025. Key provisions include: mandatory disaster audits for infrastructure projects; mandatory safety drills twice annually for industrial units; Urban Disaster Management Authorities (UDMAs) for large cities; and strengthened NDMA operational autonomy. However, critics note the Act does not create dedicated protocols for inter-state industrial disasters at jointly owned infrastructure.
📊 Current Affairs — Union Cabinet / Ministry of New & Renewable Energy · April 2026
The Union Cabinet approved the Small Hydro Power (SHP) Development Scheme 2026–31 with a total outlay of ₹2,584.60 crore to add 1,500 MW of small hydro capacity (1–25 MW projects), especially in hilly and North-Eastern states. The scheme provides ₹2,584.60 crore in central support and is designed to strengthen grid resilience and energy security through decentralised, small-scale hydropower — a policy direction that would reduce dependence on large legacy assets like Machkund.

📝 Mains Answer Framework — Machkund & Inter-State Energy Infrastructure Disasters (150 / 250 words) · 5I Approach
📖 Introduction
Open with the Machkund fire (24 May 2026) — a 70-year-old 120 MW inter-state hydropower project jointly owned by AP and Odisha, disabled by a turbine-room short circuit. Frame the issue: India's 51.41 GW large hydro fleet is the backbone of grid-balancing for its 500 GW non-fossil target, yet legacy assets lack unified safety governance. Define the structural problem: cooperative federalism in energy without cooperative disaster management.
⚡ Issues
Four issues: (1) Ageing infrastructure with deferred R&M — 70-year-old turbine electrical systems in remote, jointly administered facilities. (2) Inter-state command vacuum — fire services are a State subject (12th Schedule), but Machkund is owned by two state bodies (APGENCO + OHPC) with no unified Incident Command Structure. (3) Absence of a Critical Energy Infrastructure Protection (CEIP) framework. (4) Precedent ignored — Srisailam 2020 (9 dead) from identical cause; no mandatory upgrades mandated post-incident.
🔗 Implications
For energy security: 6-month outage of dispatchable hydro capacity in two state grids. For federalism: jurisdictional vacuum between APERC, OERC, CEA, Koraput DDMA, and both SDMAs — reconstruction cost and liability unresolved. For ecology: Eastern Ghats biodiversity, Sileru–Godavari river chain, PVTG tribal communities (Bonda, Gadaba) at risk from chemical runoff and continued industrial activity. For India's climate targets: systemic legacy hydro vulnerability undermines the grid stability that makes the 500 GW non-fossil programme viable.
🏛 Initiatives
APGENCO–OHPC 50:50 revised agreement (Oct 2020) for R, M & U. DMA Amendment Act 2025 (9 April 2025) — mandatory disaster audits for infrastructure, mandatory safety drills twice annually. SHP Development Scheme 2026–31 (₹2,584.60 crore for 1,500 MW) as resilience alternative. CDRI (2019) — 53 countries — framework for resilient infrastructure. National Electricity Plan 2023–32 — ₹9.15 lakh crore infrastructure investment plan. Electricity Act 2003 — CEA technical oversight over generation schemes.
💡 Innovation
Way forward: (1) CEA-mandated rolling R&M safety audit for all hydro plants >25 years old, as licence condition under Electricity Act. (2) Joint Disaster Management Protocol (JDMP) under Article 263 for jointly owned inter-state infrastructure. (3) CEIP framework modelled on international best practices. (4) Mandatory Environmental & Social Impact Assessment (ESIA) post-industrial disaster near ecologically sensitive areas. (5) India to leverage CDRI for an International Hydropower Resilience Standard. Conclude: cooperative federalism in energy must evolve from shared ownership to shared safety — converting the Machkund fire from a warning into a reform catalyst.
Case Matrix — Hydropower Plant Fires in India
| Project | Year | Cause | Outcome | Lesson |
|---|
| Srisailam HEP | Aug 2020 | Short circuit, left bank underground powerhouse | 9 dead (5 engineers), 15 escaped | Underground turbine rooms require dedicated fire suppression; remote rescue is deadly |
| Kwar HEP Tunnel | Nov 2025 | Load carrier vehicle fire inside construction tunnel | 39–50 workers rescued | Construction-phase fires in Himalayan tunnels — critical evacuation protocols needed |
| Machkund HEP | May 2026 | Short circuit, turbine room, 2nd floor | 2 turbines damaged, 4 workers with burns, 6-month outage | Legacy inter-state assets: absence of unified command & safety protocols is the systemic risk |
✍ Mains Tip: GS Paper III vs GS Paper II Framing
GS-III (Environment, Disaster Management): Focus on ecology of Eastern Ghats, PVTG communities, ageing hydro asset risks, NDMA–SDMA response mechanism, DMA Amendment 2025, CEIP framework. GS-II (Governance, Federalism): Focus on Entry 17 vs Entry 56 tension, dual SERC jurisdiction, Electricity Act 2003, Article 263 Inter-State Council mechanism, cooperative federalism gap in jointly owned infrastructure. Both framings are valid and examiners may ask either — prepare both angles using the same factual base.
