Why Is DLF Putting Huge Generators So Close To Homes And School?

Is the Pattern of DG Sets in Parks, Green Belts and Now Beside Residences Evidence of Systemic Disregard for Pollution Norms Across DLF Colonies?

The National Green Tribunal is currently seized of Original Application proceedings in which residents of the National Media Centre Co-operative House Building Society have laid out a detailed record of alleged non-compliance by DLF Limited. The core allegation is straightforward yet grave: twenty-four diesel generator sets with a combined capacity of 67,500 KVA, six sets of 2,250 KVA and eighteen of 3,000 KVA, are being installed, along with cooling towers and associated utility infrastructure, on a land parcel designated as Part B in the zoning plan.

That parcel, residents submit, falls outside the 32.3-acre (or, in related filings, approximately 36.36-acre) commercial project area for which environmental clearances were granted on 6 May 2019 and 9 April 2023. The clearances, they argue, do not extend to this separate portion. Construction and installation on land lacking specific environmental clearance constitutes a direct breach of the Environment (Protection) Act framework and the conditions attached to the clearances themselves.

What makes the scale of this capacity particularly concerning is not merely the number of machines but the continuous pollution load they represent once operational. A single 3,000 KVA diesel generator is an industrial-scale unit. Eighteen such units, plus six of 2,250 KVA, produce a concentrated source of particulate matter, nitrogen oxides, sulphur dioxide, carbon monoxide and noise. In a city already ranked among the most polluted urban centres in the National Capital Region, the cumulative addition of this capacity next to residential buildings, a school and a day-care centre raises immediate questions about cumulative impact assessment.

No public document produced in the proceedings demonstrates that such cumulative assessment was ever performed for the Part B location. The human consequences are not abstract. Children in the adjacent pre-primary facility, elderly residents with respiratory vulnerabilities, and families living within metres of the proposed DG rooms will inhale the exhaust plume whenever the sets operate. Noise levels from banks of large generators routinely exceed permissible residential limits, yet the proximity leaves little buffer for attenuation. The critique writes itself: if the clearances required consultation with the Haryana State Pollution Control Board precisely to evaluate such impacts, and that consultation never took place, how can the installation be treated as compliant?

The distance figures themselves demand multi-layered scrutiny. According to the developer’s own statements recorded in the residents’ submissions, the nearest DG set is approximately 15 metres from the foundation of the elevated Moulsari Avenue Rapid Metro station. Underground high-speed diesel storage in the associated yard is stated to be around 60 metres away. 15 metres is not a planning buffer; it is the width of a typical urban road. An elevated metro structure carries trains, passengers and high-voltage systems.

Vibration, heat, exhaust gases and the theoretical risk of fire or explosion from bulk diesel storage must be evaluated by the authority responsible for the metro corridor—Haryana Mass Rapid Transport Corporation Limited. Residents note that DLF has maintained no HMRTC approval is required, while the metro authorities have placed no structural or safety assessment on record.

The absence of that assessment is not a minor procedural gap. It is a failure to answer the most basic safety question: what happens to the elevated corridor, its foundations and its electrical systems if a fire or large-scale emission event occurs 15 metres away? Until that question is answered with independent engineering analysis, continued installation constitutes an ongoing gamble with public infrastructure and human life.

The environmental clearance history compounds the concern. Documents cited by residents refer to an earlier clearance dated 30 July 2007 for a proposed Mall of India shopping/commercial complex at Block V, DLF City Phase III, Sector 25A. Site preparation and excavation were carried out after that clearance, yet no construction followed and the clearance expired after five years. Fresh clearances were then obtained in 2019 and expanded in 2023.

Residents ask how the fresh clearances were granted without reference to the earlier one, and why the excavation that altered the natural contour of the land—admitted in the developer’s own documents—did not trigger fresh scrutiny of the entire site, including the Part B parcel now being used for DG sets. Concealment or misrepresentation of prior activity, if established, would undermine the validity of the later clearances. The NGT has not yet ruled on these points; the allegations remain contested. Yet the unanswered questions persist: why was the 2007 history omitted from the 2019 and 2023 applications, and why was the altered contour treated as irrelevant to the location of high-capacity generators?

Equally troubling is the documented failure of mandatory consultation. Both the 2019 and 2023 clearances required the project proponent to decide the location of DG sets only after consultation with the Haryana State Pollution Control Board. An RTI reply dated 24 July 2025, cited by residents, confirmed that the location of the DG sets and cooling substations had not been specified or decided in consultation with the Board. In a subsequent reply dated 8 January 2026, HSPCB stated that finalisation of the location of DG sets and construction of the cooling tower did not fall within its ambit.

Residents correctly challenge this position: if consultation was made a specific condition of the clearance, the Board cannot later disclaim responsibility. The condition exists precisely to ensure that pollution control expertise is applied before irreversible construction begins. When that condition is ignored, the entire regulatory chain collapses. Work continues regardless. HSPCB’s January 2026 reply indicated that DG sets had not yet been installed and the cooling tower not constructed; a later DLF communication in March 2026 stated that installation was ongoing. The timeline itself becomes evidence of persistence in the face of unresolved regulatory objections.

A revised building plan approved on 1 May 2026 shows the project spanning Sectors 24, 25 and 25A, while the earlier clearances describe it in Sector 25. Authorities have not clarified whether the additional Part B parcel is covered by any environmental clearance. The discrepancy is not semantic. Sectoral boundaries determine the applicability of clearances, zoning plans and consent-to-establish conditions issued by HSPCB.

When the physical footprint expands beyond the cleared area without corresponding amendment of the environmental clearance, the project operates in a legal grey zone. Residents have sought cancellation of the later clearances and action for alleged concealment. These prayers remain pending; the next hearing is listed for 19 November 2026. Until then, the construction proceeds under a cloud of unresolved jurisdiction.

The human scale of exposure cannot be reduced to statistics. The society houses between 3,500 and 4,000 residents. Adjacent facilities include a pre-primary school and day-care centre. Children spend their formative hours metres from a site that will house industrial generators and bulk diesel.

Elderly residents with limited mobility and higher susceptibility to particulate pollution face chronic exposure. Noise from continuous or frequent DG operation will penetrate residential windows. Fire risk is not theoretical; large diesel storage yards have produced catastrophic incidents elsewhere when containment or firefighting access proved inadequate. The proximity to a live metro corridor multiplies the potential consequences. Evacuation routes, emergency response times and secondary effects on the elevated structure have not been publicly assessed. The absence of such assessment is itself a regulatory failure.

This case does not stand in isolation. Parallel proceedings before the NGT concern the installation of approximately 30 industrial-scale diesel and gas generator sets in nine designated public parks and green belts across DLF Phase 1. Notices have been issued to CAQM, HSPCB, DTCP, Municipal Corporation Gurugram, DHBVNL and DLF entities. A similar matter relating to Malibu Towne is already pending. Separately, the Department of Town and Country Planning has placed more than 50 DG sets located in green belts, parks, road margins and other public spaces across DLF Phases 1 to 4 under scrutiny, seeking permissions, NOCs and statutory approvals.

The pattern that emerges is one of repeated placement of high-capacity generators in spaces never intended for industrial equipment—parks meant for recreation, green belts meant for ecological buffering, and now a parcel adjacent to homes and metro infrastructure that was never covered by the project’s environmental clearances. Each instance raises the same fundamental questions: who authorised the location, what pollution modelling was performed, and why were residential and public amenities treated as acceptable externalities?

Air quality data for the National Capital Region consistently identify diesel generators as significant contributors to particulate and black carbon loads. Studies cited in regulatory discussions estimate that DG sets across the NCR release tens of thousands of tonnes of PM10 and PM2.5 annually, along with substantial quantities of nitrogen oxides and carbon monoxide. Adding 67,500 KVA of new capacity in a dense residential-metro interface does not occur in a vacuum; it adds to an already overloaded atmospheric system.

The Commission for Air Quality Management has imposed strict conditions on DG operation in the NCR, including requirements for emission-control devices or dual-fuel kits. Whether the sets under installation will meet those standards, and whether continuous monitoring will be enforced, remains unaddressed in the public record of this case. The critique is unavoidable: regulators possess the legal tools to demand compliance; their failure to apply those tools before construction advances converts environmental law into an after-the-fact exercise.

The procedural sequence itself invites interrogation. Environmental clearances impose conditions. Those conditions require consultation. Consultation does not occur. Construction proceeds. RTI replies confirm the gap. HSPCB later claims the matter is outside its ambit. Metro authorities remain silent on structural assessment. Building plans expand sectoral coverage without corresponding clearance amendment. Residents are left to litigate each discrete violation while the physical installation continues. This sequence is not the product of isolated oversight; it is the predictable outcome of a regulatory culture that treats developer timelines as more urgent than precautionary principle. The National Green Tribunal exists precisely to interrupt that culture. Whether it will do so before the generators become operational is the open question listed for November 2026.

Fire and explosion risk deserve independent, exhaustive examination. Bulk diesel storage underground, even at 60 metres, creates a hazard envelope. Diesel vapour, ignition sources from electrical systems or maintenance activity, and the proximity of high-voltage metro infrastructure form a combination that standard industrial safety protocols would subject to quantitative risk assessment. No such assessment appears on the public record. The developer’s assertion that no HMRTC approval is required does not substitute for independent evaluation. When critical public infrastructure is placed at risk, the burden of proof cannot rest on residents to prove danger; it must rest on the proponent to demonstrate safety beyond reasonable doubt. That demonstration has not been made.

Noise pollution from banks of large DG sets is another dimension routinely underestimated. Industrial generators operating under load produce continuous broadband noise that travels through open windows and building structures. Residential ambient standards under the Noise Pollution (Regulation and Control) Rules are strict. The absence of a dedicated noise modelling study for the specific topography and building layout adjacent to the Moulsari Avenue site leaves residents without assurance that those standards will be met. Cooling towers add their own mechanical noise. The cumulative acoustic environment has not been publicly characterised.

The 2007 clearance history introduces a further layer of evaluative concern. Excavation that altered natural contours was undertaken under a clearance that later expired. Fresh clearances were obtained years later without apparent reference to that prior activity. Residents allege concealment and misrepresentation. If the altered contour affected drainage, soil stability or the suitability of adjacent parcels for heavy machinery, those effects should have been re-evaluated. The fact that they appear not to have been re-evaluated raises questions about the completeness of the environmental impact assessment process that underpinned the 2019 and 2023 clearances.

Sectoral description discrepancies in successive approvals further erode confidence. When a revised building plan suddenly encompasses additional sectors while the environmental clearances remain anchored to an earlier description, the legal coverage of the expanded footprint becomes ambiguous. Ambiguity in environmental law is not a technicality; it is a pathway for unassessed impacts. Authorities have not resolved the ambiguity. Until they do, every cubic metre of concrete poured on Part B stands on contested legal ground.

The broader pattern of DG placement across DLF colonies—parks in Phase 1, green belts in Phases 1–4, and now the Moulsari Avenue interface—suggests that the company has treated common and peripheral spaces as convenient locations for backup power infrastructure without rigorous adherence to land-use and environmental constraints. DTCP’s ongoing scrutiny of more than fifty such installations indicates that the problem is recognised at the planning department level. Recognition without enforcement, however, leaves residents exposed. The NGT’s parallel proceedings offer one avenue for accountability; the question is whether the institutional response will match the scale of the alleged non-compliance.

Every data point in this record invites the same interrogative stance. Why was the Part B parcel never brought under the environmental clearance? Why was the mandatory HSPCB consultation skipped? Why has no metro safety assessment been placed on record despite 15-metre proximity? Why does construction continue after RTI confirmation of non-consultation? Why was the 2007 excavation history omitted from later applications? Why do building plans expand sectoral coverage without corresponding clearance amendment?

Each unanswered question compounds the next. The human beings who live, learn and age within metres of the site cannot wait indefinitely for regulatory clarity. Their exposure is continuous and cumulative. The law exists to prevent precisely this outcome. Its selective application in the face of documented gaps is the central concern that the National Green Tribunal must now confront.

The capacity figure of 67,500 KVA itself requires further unpacking. Converting KVA to approximate real power (assuming a typical power factor) yields a multi-megawatt installation. Multi-megawatt diesel generation next to residential buildings is industrial activity by any ordinary planning definition. The environmental clearances were issued for a commercial project; the placement of industrial-scale generation plant on an uncleared adjacent parcel transforms the character of the development. That transformation should have triggered a fresh environmental impact assessment. It did not. The regulatory silence on this point is as troubling as the physical installation itself.

Cooling towers associated with the DG installation introduce additional water use, chemical treatment and potential drift emissions. Their location outside the cleared project area means that these secondary impacts were never evaluated under the original clearances. Cumulative water demand, wastewater quality and atmospheric emissions from the towers remain unassessed for the specific residential-metro context. Again, the precautionary principle is inverted: construction precedes evaluation.

The timeline of official replies reveals a pattern of delayed or incomplete engagement. HSPCB’s January 2026 statement that sets had not yet been installed was followed by DLF’s March 2026 acknowledgement that installation was under way. Residents rely on these successive replies to demonstrate ongoing activity despite unresolved objections. The gap between regulatory knowledge and enforcement action is the space in which irreversible facts on the ground are created. Once the generators are commissioned, removal or relocation becomes exponentially more difficult. The window for precautionary intervention is therefore closing.

Residents have not merely complained; they have produced documentary evidence drawn from the developer’s own environmental documents, zoning plans, RTI replies and successive official communications. The burden now shifts to the respondents, State of Haryana, SEIAA Haryana, HSPCB, HMRTC, DTCP and DLF itself, to demonstrate that every statutory condition has been met. The public record so far does not contain that demonstration.

Until it does, the installation of 24 high-capacity DG sets on land outside the cleared project area, without the required pollution-board consultation, and within metres of homes, a school and a live metro corridor, stands as a case study in regulatory failure and corporate persistence.

The interrogative tone of this article is not rhetorical flourish. It is the only appropriate response to a factual record that multiplies questions while answers remain scarce. How many more metres of proximity, how many more megawatts of capacity, how many more ignored conditions will be required before the institutional machinery of environmental governance asserts itself with the force the law contemplates?

The residents of National Media Centre, the children in the adjacent school, the passengers on the elevated metro, and the broader public that relies on both environmental law and public infrastructure deserve a clearer answer than continued construction under a cloud of unresolved allegations. The National Green Tribunal’s next hearing offers one opportunity. Whether that opportunity is seized with the seriousness the risks demand remains the open, urgent question.
