GIS for DISCOMs: Network Mapping, Loss Reduction and Field Efficiency

A power distribution utility sells a product that travels along wires to millions of fixed addresses, so almost every decision it makes is a location decision. Which feeder serves which colony, which transformer a meter hangs from, where energy leaks between the substation and the bill: these questions only have answers when the network and the consumers sit on one accurate map. GIS turns scattered registers, single line diagrams and billing files into a connected network model. That model lets a DISCOM audit energy by feeder and transformer, find losses, plan works and direct field crews from the same source of truth.

What the evidence shows

21.91% to 16.16%[3]

National AT&C loss, FY2021 to FY2025

The Ministry of Power reported this decline as RDSS and related reforms took hold. Further gains depend on locating the remaining losses at feeder and transformer level.

India's distribution sector: large reform funding, tight loss targets

The Revamped Distribution Sector Scheme (RDSS), launched by the Ministry of Power in 2021, carries an outlay of Rs 3,03,758 crore with an estimated central grant of Rs 97,631 crore. Its stated goals are to bring aggregate technical and commercial (AT&C) losses down to a pan-India band of 12 to 15 percent and to close the gap between the average cost of supply and average revenue realised. Grant release is linked to how each utility performs against these loss and finance parameters, so measurement quality now has a direct effect on funding.

Progress is real but uneven. The Ministry reported that national AT&C losses fell from 21.91 percent in FY2021 to 16.16 percent in FY2025, and DISCOMs recorded a combined profit of over Rs 2,700 crore in 2024-25. That followed a difficult stretch: PRS Legislative Research noted state-owned DISCOMs reported losses of Rs 68,832 crore in 2022-23 and carried outstanding debt of Rs 6.61 lakh crore. Holding these gains requires losses to be located and fixed feeder by feeder, not just averaged at state level.

The work is spatial at every level. RDSS has sanctioned smart metering for 19.79 crore consumers, 52.53 lakh distribution transformers and 2.05 lakh feeders, and its guidelines call for an automated feeder and DT level energy accounting system. Meter data only becomes an energy audit when each consumer is correctly linked to its transformer and feeder. The earlier R-APDRP programme had already made consumer indexing, GIS mapping and asset mapping of the network at and below 11 kV, including poles and LT lines, a precondition for funding.

The challenges

Where productivity is lost today

01

Broken consumer-to-network links

Billing systems often record a consumer's address but not the transformer, LT circuit and pole that actually serve them. When feeders are reconfigured or new connections are added without field updates, the links decay. Energy audits then show false losses on one transformer and impossible gains on another, and loss reduction effort is spent in the wrong places.

02

Outdated asset and network maps

Many utilities still rely on maps created during R-APDRP or on paper single line diagrams that no longer match the ground. Missing poles, re-routed lines and unrecorded transformers make planning, load balancing and outage tracing slow, and capital works under RDSS risk being designed against a network that has already changed.

03

Smart meter data without spatial context

Prepaid smart meters, DT meters and feeder meters generate large volumes of interval data. Without a reliable network hierarchy and a location for each meter, utilities struggle to turn that data into transformer-level loss figures, tamper hotspots or reliability indices that field offices can act on.

04

Locating commercial losses

Theft, bypassed meters and unbilled connections concentrate in specific pockets, yet inspection teams are often routed by complaint or by rota rather than by evidence. Untargeted raids cost staff time, strain community relations and leave high-loss areas unvisited, while the AT&C figure drives grant eligibility.

05

Slow outage response and limited crew visibility

When a fault occurs, control rooms may not know quickly which consumers are affected or where the nearest crew is. Without live crew positions and a mapped network, restoration depends on phone calls and local memory, which stretches outage durations and weakens supply reliability scores.

06

Vegetation and right-of-way exposure

Overhead lines run through trees, plantations and encroached corridors. Vegetation contact is widely recognised as a leading cause of outages on overhead networks, but clearance work is often scheduled on fixed cycles rather than actual risk, so crews trim low-risk spans while high-risk spans fail during storms.

How GLOBEIR helps

Business needs and how we solve them

Each solution starts from a need Power Distribution Utilities (DISCOMs) faces today, then shows how GLOBEIR delivers it and what changes as a result.

01 · The business need

RDSS has sanctioned Rs 1.53 lakh crore of loss reduction infrastructure works such as reconductoring, LT aerial bunched cable and DT augmentation. Designing and verifying those works needs a network map that matches the ground today. Maps built a decade ago under R-APDRP, or paper single line diagrams, no longer show where the network has changed.[3]

GIS Mapping

Electrical network and asset GIS

GLOBEIR builds a connected GIS of the distribution network from substation to service point: 33 kV and 11 kV feeders, distribution transformers, LT circuits, poles, switches and meters. Topology rules check that every asset is connected and every consumer traces back through one DT and one feeder. Existing R-APDRP layers, single line diagrams and survey data are reconciled into one geodatabase that planning, operations and billing teams can share.

  1. 1Audit existing R-APDRP layers, single line diagrams and asset registers for gaps
  2. 2Digitise and update feeders, DTs, poles and LT lines from imagery and survey
  3. 3Apply topology rules so every consumer traces to one DT and feeder

The result

Planners and field engineers work from one current network model instead of reconciling paper diagrams and spreadsheets.

02 · The business need

RDSS calls for an automated energy accounting system at feeder and DT level, and that only works if every consumer is linked to the transformer that serves it. Billing addresses do not carry that link, and indexing done years ago has decayed with new connections and network changes, so a fresh, validated field survey is needed.[1]

Field Validation

Consumer indexing and door-to-door field survey

Field teams using the My GLOBEIR mobile survey app visit each service connection, capture GPS position, meter number, photographs and the pole and transformer it is fed from, and flag unmetered or unauthorised connections. Records are checked on the device against the network map and pushed to a central database, so mismatches between billing and the ground are caught during the survey rather than months later.

  1. 1Plan survey zones by feeder and DT using the network map
  2. 2Capture GPS, meter, photographs and supplying pole for each connection in-app
  3. 3Validate records against the map and re-check a sample in the field

The result

Each consumer is tagged to its feeder and DT, which is the foundation for a credible energy audit.

03 · The business need

Grant release under RDSS is linked to AT&C loss and ACS-ARR performance, so DISCOMs must show where losses sit and whether works are reducing them. National AT&C loss was 16.16 percent in FY2025 against a 12 to 15 percent target band. Manual, state-level loss estimates cannot point managers to the specific feeders and transformers responsible.[3]

Data Analysis

Feeder and DT level energy audit

GLOBEIR links feeder and DT meter readings with consumer billing through the indexed network hierarchy and computes input energy, billed energy and loss for each feeder and transformer. Results are mapped so that high-loss transformers, overloaded circuits and indexing errors stand out geographically. Month-on-month comparison shows whether loss reduction works and meter replacements are actually moving the numbers.

  1. 1Link feeder, DT and consumer meter data through the indexed hierarchy
  2. 2Compute monthly input, billed energy and loss per feeder and DT
  3. 3Map and rank high-loss assets and flag likely indexing errors

The result

Loss reduction effort moves from state averages to a ranked list of specific feeders and transformers.

04 · The business need

With 19.79 crore consumer smart meters sanctioned under RDSS, utilities are receiving far more consumption data than vigilance teams can review by hand. Commercial losses such as theft and bypassing still weigh on AT&C figures, and inspections routed by complaint or rota miss many of them while consuming scarce staff time.[2]

Machine Learning

Loss and theft hotspot detection

Machine learning models score consumers and transformers for suspected non-technical loss using smart meter consumption patterns, energy balance gaps, tamper events and neighbourhood context. Clustering and anomaly detection methods of the kind described in research on smart meter data highlight unusual consumption profiles, and spatial hotspot analysis groups them into inspection zones. Inspection outcomes feed back to improve the models over time.

  1. 1Combine meter patterns, tamper events and DT energy balance gaps into features
  2. 2Train anomaly and classification models and group flagged cases into hotspots
  3. 3Feed inspection outcomes back to retrain models and refine targeting

The result

Vigilance teams inspect the connections most likely to show losses instead of working by rota.

05 · The business need

RDSS aims to improve the quality and reliability of supply, and its guidelines note that many consumers still do not get reliable 24x7 power. Restoring supply quickly depends on sending the nearest suitable crew, but most field offices still coordinate by phone without knowing where crews are or what they have completed.[1]

Live Tracking

Field crew tracking and work dispatch

Line crews, meter installers and inspection teams carry the mobile app, which reports their location and job status to a control room map. Supervisors see which crews are nearest to a fault or a pending installation and assign work on the map. Completed jobs return with photographs, timestamps and asset updates, so the GIS stays current as work is done.

  1. 1Equip line, metering and inspection crews with the mobile tracking app
  2. 2Show crew positions and open jobs on a shared control room map
  3. 3Close jobs with photographs and timestamps that update the GIS

The result

Faster crew assignment and verified job completion with less phone-based coordination.

06 · The business need

RDSS guidelines require communicable meters on all feeders so that energy accounting and reliability indices such as SAIFI and SAIDI can be calculated. Utilities now have the readings but often lack a single view that ties outages to affected consumers, crews and repeat fault locations, which is what managers need to act and to report.[1]

Monitoring Systems

Outage and reliability monitoring dashboards

GLOBEIR builds web dashboards that combine the network GIS with outage logs, feeder meter data and crew positions. When a feeder or transformer trips, the dashboard shows affected consumers and areas, active crews and restoration status. Over time the same data supports feeder-wise reliability reporting and helps managers see where repeated faults justify reconductoring or other infrastructure works.

  1. 1Connect the network GIS with outage logs, feeder meters and crew data
  2. 2Build WebGIS dashboards showing affected consumers and restoration status
  3. 3Add feeder-wise reliability reports and repeat fault maps for planning

The result

Control rooms and management see outages, affected consumers and restoration progress in one view.

07 · The business need

PM Surya Ghar targets rooftop solar for 1 crore households by March 2027, adding generation at the edge of LT networks that were designed for one-way flow. At the same time, tree contact is widely seen as a leading cause of overhead line outages. Fixed trimming cycles and connection-by-connection solar approvals do not show where risk is building.[6]

Remote Sensing

Vegetation, right-of-way and rooftop solar mapping

High resolution satellite or drone imagery is used to map tree cover and encroachment along overhead line corridors, ranking spans by vegetation risk so clearance work targets the right places. The same imagery supports rooftop mapping that estimates usable roof area at feeder and DT level, helping a DISCOM anticipate where rooftop solar under PM Surya Ghar will add generation or reverse power flow.

  1. 1Acquire recent high resolution satellite or drone imagery over line corridors
  2. 2Map vegetation and encroachment by span and usable rooftop area by DT
  3. 3Rank spans for clearance and DTs for solar impact in dashboards

The result

Vegetation work and distributed solar planning are driven by mapped evidence rather than fixed cycles and guesswork.

1. RDSS Works Monitoring and Results Evidence

The Revamped Distribution Sector Scheme is results-linked: money flows only when a utility shows progress against loss and finance parameters. Under the scheme, projects worth Rs 2.83 lakh crore have been sanctioned, of which Rs 1.53 lakh crore is for distribution infrastructure such as conductor replacement, LT aerial bunched cable, transformer augmentation and agricultural feeder segregation [3]. Smart metering works alone cover 45 distribution utilities in 28 States and UTs [2].

The guidelines go beyond physical works. They provide for SCADA and Distribution Management Systems in about 100 larger towns and basic SCADA in 3,875 other statutory towns through district or circle-level control centres, require all feeders to be integrated with a National Feeder Monitoring System, and fund AI and ML tools that turn the monthly energy accounting reports into actionable management information on loss reduction, demand forecasting, asset management and renewable integration [1]. Each of these outputs is organised by feeder, transformer, town or circle, which means each one is a map layer as much as a table.

In practice, a single DISCOM may be running hundreds of work packages at once across many divisions, executed by several contractors, with a Project Management Agency appointed to support implementation [1]. Tracking whether a sanctioned reconductoring stretch, a new DT or an AB cable section was actually built where the DPR said, and whether it moved the loss figure on that feeder, is a spatial reconciliation problem.

Business problem

  • Progress on RDSS works is often reported as counts and percentages per circle, with no reliable link to the feeder or DT the work was meant to fix. Managers cannot easily see whether money is going to the highest-loss parts of the network.
  • Contractor claims, PMA verification and utility records are kept in separate spreadsheets, so disputes over what was done, where and when take time to resolve.
  • Grant release depends on demonstrated loss and ACS-ARR performance [3], yet the evidence trail from a physical work to a measured result on a specific feeder is rarely assembled in one place.

Our solution

  • A works monitoring layer on top of the network GIS: every sanctioned package is mapped to the feeders, DTs and line sections it covers, with planned versus executed geometry.
  • Field verification through the My GLOBEIR app: geotagged, timestamped photographs and checklists for each completed work, captured by utility engineers or PMA staff and reviewed on a WebMap dashboard.
  • Administration monitoring dashboards that roll up progress by division, circle and contractor, alongside the before-and-after loss trend on each treated feeder.
  • Exportable evidence packs for review meetings, organised by feeder and work type.

Benefits

  • One view of what was sanctioned, what was built and where, replacing manual reconciliation of contractor and utility records.
  • Investment can be checked against the loss map, so works target the feeders that need them most. RDSS itself links fund release to AT&C and ACS-ARR performance (industry context) [3].
  • Faster resolution of measurement and completion disputes because each claim carries a location, photograph and timestamp.
  • A ready base for the AI and ML analytics that the scheme explicitly encourages on monthly energy accounting data (industry context) [1].

Privacy & data security

  • Data involved: asset locations, works photographs, contractor and staff identities, and the GPS positions of field verifiers during inspections.
  • Role-based access: contractors see only their own packages; PMA, division and headquarters users see what their role requires, with audit logs of every change.
  • Critical infrastructure care: detailed network and substation layers are treated as sensitive operational data and kept on India-hosted or utility-controlled infrastructure, in line with the power sector's cyber security expectations [12].

2. Consumer Indexing and Network Asset Mapping

Consumer indexing ties every service connection to the pole, LT circuit, distribution transformer and feeder that supplies it. Asset mapping records the network itself: substations, HT and LT lines, poles, transformers, switches and meters, with their connectivity. Together they form the hierarchy that energy accounting depends on.

India has done this before, but not everywhere. R-APDRP made consumer indexing, GIS mapping and asset mapping of the network at and below 11 kV a part of baseline data preparation, but its project area was urban towns and cities with a population above 30,000, or above 10,000 in special category States [5]. Rural networks and smaller towns were largely outside that scope, and the urban data has aged as cities have grown. RDSS notes that IT measures under IPDS and R-APDRP, including GIS mapping of consumers and asset mapping, were carried out mainly in urban areas [1].

The pace of new connections makes the problem worse. The Electricity (Rights of Consumers) Rules, as amended in 2024, require a new connection within 3 days in metropolitan areas, 7 days in other municipal areas and 15 days in rural areas [15]. Connections released that quickly are rarely indexed to the correct DT at the same time unless indexing is built into the connection workflow.

Business problem

  • Indexing done a decade ago no longer matches the ground. Feeder reconfigurations, new DTs and load shifting have moved consumers between transformers without the records following them.
  • Rural and peri-urban networks, where many RDSS loss reduction works are planned, often have no reliable digital map at all.
  • Time-bound connection rules push field offices to release connections quickly, and the network link is the field most often skipped [15].
  • Survey campaigns run by multiple agencies produce inconsistent data that is hard to merge into the utility's GIS and billing systems.

Our solution

  • Gap assessment of existing R-APDRP and IPDS layers against recent imagery and billing extracts, to decide where to update and where to map afresh.
  • Network digitisation from high resolution imagery and field survey, following the utility's data model and topology rules, delivered through GIS mapping and cartography services.
  • Door-to-door indexing with the My GLOBEIR app under mobile GIS workflows: offline capture, mandatory fields, photographs of meter and pole, and on-device checks against the mapped network.
  • Digital micro mapping of dense areas where individual buildings, lanes and service cables must be resolved precisely.
  • A maintenance workflow so that every new connection, shifting or disconnection updates the consumer-to-DT link at the time it is executed, not in the next survey cycle.

Benefits

  • A consumer-to-DT-to-feeder hierarchy that energy accounting can trust, which R-APDRP treated as a prerequisite for measuring losses (industry context) [5].
  • Extension of mapping to rural and smaller-town networks that earlier programmes did not cover (industry context) [5].
  • Fewer false loss signals caused by mis-indexed consumers, so field effort goes where losses are real.
  • A living map that stays current as connections are released within the regulated timelines [15].

Privacy & data security

  • Data involved: consumer names, account and meter numbers, premises locations and photographs of meters and buildings. Location plus account identity is personal data under the DPDP Act [19].
  • Minimum necessary capture: survey forms collect only what indexing needs; photographs are framed on the meter and pole, not on people or interiors.
  • Encrypted capture: app data is encrypted on upload (TLS 1.2 or higher) and stored with AES-256 encryption at rest, with offline records synced only to the agreed server.
  • India-only processing: detailed network and premises mapping is stored and processed in India, consistent with the DST geospatial guidelines [22].

3. AT&C Loss and Theft Hotspot Analysis

AT&C loss combines technical loss in wires and transformers with commercial loss from unmetered, under-billed, stolen or unpaid energy. National figures have improved, but the remaining loss sits in specific feeders, transformers and pockets. RDSS requires a feeder and DT level automated online energy accounting system and funds AI and ML tools to turn those accounts into monthly actionable reports [1].

The method is straightforward once indexing is sound. Input energy at the feeder and DT meter is compared with the sum of billed consumption beneath it. Large gaps flag a problem; spatial analysis then shows whether high-loss DTs cluster, whether they share a feeder or a type of area, and whether a gap is more likely a technical issue (long LT runs, overloaded or undersized conductors) or a commercial one. Research on smart meter data shows that consumption patterns themselves can reveal likely theft: a study combining principal component analysis with mean shift clustering reported encouraging results in detecting power theft among residential consumers [11].

Earlier programmes used independent verification of input energy and collection over at least three billing cycles to fix a baseline loss level [5]. The same discipline of verified baselines and repeat measurement is what lets a utility show that a loss reduction work actually delivered.

Business problem

  • Loss figures are often reliable only at division or circle level, so action is spread thinly instead of concentrated on the DTs that account for most of the gap.
  • Indexing errors, defective meters and real theft all look the same in a raw energy balance, and inspection teams waste visits separating them.
  • Vigilance work routed by complaint or rota misses persistent hotspots and risks repeated visits to the same compliant consumers.
  • Without a before-and-after comparison by feeder, it is hard to prove which interventions worked.

Our solution

  • Monthly feeder and DT energy audit computed through the indexed hierarchy, with loss maps and ranked lists, built with geospatial data science workflows.
  • Error triage that separates likely indexing errors, metering faults and suspected commercial loss before any field visit.
  • Anomaly detection and hotspot analysis on meter data, tamper events and DT energy gaps using AI/ML geospatial models, with results shown as heat maps at DT and feeder level.
  • Inspection planning that groups flagged connections into efficient routes and records each inspection outcome in the mobile app, feeding back into model training.

Benefits

  • Loss reduction effort concentrated on the specific DTs and feeders that drive the gap, in line with the RDSS emphasis on DT level accounting (industry context) [1].
  • Higher inspection productivity because likely indexing and metering faults are fixed first, without a vigilance visit.
  • Data mining on smart meter consumption has shown encouraging results for residential theft detection in published research (industry example) [11].
  • Evidence of impact by feeder, supporting the results-linked funding conditions of RDSS (industry context) [3].

Privacy & data security

  • Asset-first analysis: models score meters, DTs and feeders on energy and consumption behaviour. No analysis uses personal or community attributes of consumers.
  • Pseudonymised modelling: consumption series are analysed against meter identifiers; names and contact details are joined only for confirmed inspection lists, and only for authorised vigilance staff.
  • Human decision: a model flag is a reason to inspect, not a finding. Final decisions remain with authorised utility officers under the utility's procedures.
  • Purpose limitation: consumption data is used only for the agreed loss reduction purpose and never used to train models for other clients.

4. Smart Meter Rollout Planning and AMI Integration

RDSS has turned smart metering into the largest field programme in Indian distribution. Against 19.79 crore sanctioned consumer meters, 3.90 crore had been installed under the scheme by 31 December 2025, and 5.28 crore smart meters had been installed across all schemes [2]. The gap between sanction and installation is a logistics challenge spread over millions of premises.

The guidelines set clear priorities for the first phase: all Union Territories, electricity divisions in AMRUT cities with AT&C losses above 15 percent, industrial and commercial consumers, government offices at block level and above, and other high-loss divisions [1]. Areas without a communication network may take prepayment meters instead, and all DTs other than those feeding only agricultural consumers and those below 25 kVA are to carry communicable meters [1]. Every one of these rules is easier to apply on a map than in a list: AMRUT boundaries, loss levels by division, network coverage and DT capacity can all be overlaid.

Consumer trust matters as much as installation speed. Since 2024, a utility must install an additional check meter within five days of a consumer complaint that the meter reading does not match actual consumption, and use it for at least three months [15]. A REC and PFC feedback survey found that of 1,24,590 consumers who had downloaded the smart meter app, 54,321 were aware of its real-time consumption feature [2], which shows how much awareness work remains.

Business problem

  • Installation agencies need daily targets by area, but sanctioned quantities are held as division totals with no premises-level plan.
  • Meters installed without a verified location and network link create AMI data that cannot be used for DT energy accounting.
  • Communication coverage gaps are discovered at installation time, causing repeat visits and stranded meters.
  • Complaints about readings and prepaid balances cluster in particular areas, and utilities often cannot see the pattern quickly enough to respond with awareness drives or meter testing.

Our solution

  • Rollout planning maps that combine indexed consumers, AMRUT and loss boundaries, DT capacity and communication coverage to sequence installation by priority category [1].
  • Installer tracking through Live Tracking and the My GLOBEIR app: each installation is logged with GPS, old and new meter photographs and seal details, and validated against the GIS record.
  • AMI-GIS reconciliation that flags meters reporting from the wrong DT, non-communicating meters and duplicate identifiers.
  • Complaint and awareness dashboards on WebGIS that map check meter requests, recharge issues and app adoption by area, so awareness camps go where they are needed.

Benefits

  • A premises-level plan for converting sanctioned quantities into installed meters; nationally, 3.90 crore of 19.79 crore sanctioned consumer meters were in place by December 2025 (industry context) [2].
  • AMI data that is usable for DT and feeder accounting from the day of installation.
  • Fewer repeat visits through upfront planning of communication gaps and prepayment meter areas [1].
  • Faster, location-aware response to consumer complaints within regulated timelines [15].

Privacy & data security

  • Data involved: interval consumption, prepaid balance and recharge records, tamper events, meter locations and installer movements. Fine-grained consumption can reveal household routines and is personal data under the DPDP Act [19].
  • Aggregation by default: rollout and adoption dashboards show area or DT level summaries; individual consumption is visible only to authorised roles.
  • Aligned with procurement terms: the RDSS Standard Bidding Document for smart metering already covers communication security, cloud security, incident management and DPDP compliance [2]; GLOBEIR follows the client's SBD obligations and security policies.
  • Installer tracking is work-only: background tracking in the app is optional and opt-in, with a persistent notification while it runs.

5. Outage Management, Field Crews and Vegetation Along Lines

The Electricity (Rights of Consumers) Rules require distribution licensees to supply power 24x7 to all consumers, with lower hours permitted for some categories such as agriculture, and to put in place a mechanism, preferably with automated tools, for monitoring and restoring outages [14]. Automatic compensation is to be paid for performance standards that can be monitored remotely, including no supply beyond a specified duration and interruptions beyond specified limits [14]. Feeder metering under RDSS exists partly so that SAIFI and SAIDI can be calculated [1].

Restoration time is mostly a field problem: finding the fault, getting the right crew there and confirming the fix. A connected network GIS tells the control room which consumers sit downstream of a tripped switch; live crew positions tell it who can get there first.

Vegetation is a large and often unmapped cause of faults on overhead lines. The US Federal Energy Regulatory Commission's vegetation management review found that at many utilities, 80 to 90 percent of vegetation management funding and resources go to distribution rather than transmission, because distribution networks are so much longer [10]. It noted that most utilities did not have an inventory of the vegetation they manage, that trimming "cycles" across the industry ranged from 1 to more than 10 years, and that fixed cycles are not a sufficient way to ensure problems are addressed in time [10]. Imagery-based mapping of tree cover along corridors is the practical way to build that missing inventory.

Business problem

  • Fault calls arrive at call centres and sub-division offices, but there is no quick way to see which consumers are affected and whether several calls point to the same fault.
  • Crew dispatch relies on phone calls; supervisors do not know which crew is nearest or free.
  • Compensation obligations tied to outage duration and frequency [14] make long restorations a financial as well as a service problem.
  • Tree clearance follows fixed schedules or complaints rather than measured risk, so high-risk spans may fail in storms while low-risk spans are trimmed.

Our solution

  • Outage dashboards that trace affected consumers from the faulted device through the network GIS, cluster incoming complaints by location and show restoration status, built under monitoring systems and WebGIS services.
  • Crew tracking and dispatch with Live Tracking: nearest available crew, job assignment on the map and job closure with photographs and timestamps.
  • Repeat-fault mapping that shows which feeder sections and DTs trip most often, to guide reconductoring, AB cable and other RDSS works.
  • Vegetation risk mapping from high resolution satellite or drone imagery using remote sensing methods: canopy near conductors by span, ranked for clearance, with clearance work recorded and verified in the field app.

Benefits

  • Faster identification of affected consumers and crew assignment, supporting the monitoring and restoration mechanism the Rules call for (industry context) [14].
  • Evidence for feeder-wise reliability reporting based on the feeder metering that RDSS mandates (industry context) [1].
  • A vegetation inventory where most utilities have none, and a move away from fixed cycles that the FERC review considered insufficient (industry example) [10].
  • Clearance budgets directed to the spans that cause faults, where distribution can absorb 80 to 90 percent of vegetation spending (industry example) [10].

Privacy & data security

  • Data involved: crew GPS trails, consumer complaint records with phone numbers and addresses, and imagery of corridors that may include private property.
  • Opt-in work tracking: crew tracking runs only for work purposes, is optional and opt-in in the My GLOBEIR app, and shows a persistent notification while active.
  • Complaint data minimisation: outage maps show affected areas and counts; complainant contact details stay in the call-centre system and are visible only to authorised staff.
  • Imagery handling: high resolution corridor imagery and derived maps are stored and processed in India, as the DST guidelines require for finer-than-threshold data [22].

6. Rooftop Solar, Agricultural Feeders and DER Planning

Distributed generation is arriving on LT networks faster than many utilities planned for. PM Surya Ghar had more than 33 lakh rooftop systems installed by May 2026, adding over 12 GW, with a record 3.16 lakh installations in May 2026 alone and more than 65 lakh applications in the pipeline [16]. The Ministry expects to cross 75 lakh households by December 2026, and a Utility-Linked Aggregation model, under which about 30 lakh installations have been planned with utilities playing a key role, puts DISCOMs directly in the delivery chain [16].

Regulation has shifted the burden of network readiness to the utility. Since 2024, systems up to 10 kW no longer need a technical feasibility study; for larger systems the study must finish in 15 days or approval is deemed given; distribution strengthening needed for systems up to 5 kW is done at the DISCOM's own cost; and commissioning must happen within 15 days [15]. The utility therefore needs to know in advance which DTs are approaching their limits.

The same logic applies to agriculture. RDSS gives priority to segregating feeders that serve only agricultural load where they are to be solarised under PM-KUSUM, and once segregated those feeders are not to serve other consumers [1]. Identifying which feeders qualify, and where farm load and solar potential coincide, is a mapping exercise.

Business problem

  • Rooftop applications are approved one by one, so the cumulative effect on a DT or LT circuit is invisible until voltage or reverse flow problems appear.
  • With feasibility studies waived for small systems and strengthening costs falling on the DISCOM [15], unplanned DT upgrades can strain budgets.
  • Utility-led aggregation needs target lists of suitable roofs and households by DT, which most utilities do not have [16].
  • Agricultural feeder segregation and solarisation decisions depend on knowing which consumers sit on mixed feeders today [1].

Our solution

  • Rooftop potential mapping from high resolution imagery: usable roof area, shading and orientation, summarised by DT and feeder through 3D mapping and remote sensing workflows.
  • DER penetration dashboards that sum approved and commissioned rooftop capacity against DT rating and LT circuit length, flagging DTs likely to need strengthening before it becomes urgent.
  • Aggregation planning maps for utility-led rooftop programmes, showing clusters of suitable roofs on DTs with headroom.
  • Agricultural feeder analysis that maps farm connections, mixed feeders and candidate solarisation feeders using the indexed network.

Benefits

  • Visibility of cumulative rooftop capacity per DT at a time when installations exceed three lakh a month (industry context) [16].
  • Planned, budgeted strengthening for small systems that the DISCOM must now fund itself (industry context) [15].
  • Better targeting for utility-led aggregation, where about 30 lakh installations have been planned across States (industry context) [16].
  • A clear basis for prioritising agricultural feeder segregation under RDSS (industry context) [1].

Privacy & data security

  • Data involved: roof geometry from imagery, applicant details from the national portal or utility systems, and generation and export readings from net meters.
  • Analysis at DT level: rooftop potential and DER penetration are reported by DT and feeder; household-level outputs are limited to the utility's authorised programme teams.
  • Imagery and 3D models in India: building-level imagery and models are finer-than-threshold geospatial data and are kept on servers in India, never passed to non-Indian entities [22] [23].

7. Other Networked Utilities: City Gas and Water

The same building blocks of a connected network map, indexed customers, field-captured assets and tracked crews apply to other utilities with buried or overhead networks.

City gas distribution. City gas coverage has expanded to 307 geographical areas, and domestic PNG connections reached about 1.57 crore by September 2025, with over 8,400 CNG stations [18]. Every new connection and every metre of pipe laid needs an as-built record, because a buried steel or polyethylene main that is not on the map is a safety risk for every later excavation.

Rural and urban water supply. Jal Jeevan Mission had provided tap water connections to 15.19 crore rural households (78.58 percent) by October 2024, and its monitoring system includes geo-tagging of assets created, third-party inspection before payment and sensor-based IoT measurement of supply [17]. As the focus shifts from building connections to sustaining service, utilities need the asset map to plan operations, leak repair and quality testing.

Business problem

  • Gas and water networks are largely underground; as-built records captured on paper or by multiple contractors are incomplete and hard to merge.
  • Rapid connection drives in both sectors [17] [18] add assets faster than records are updated.
  • Field teams for meter reading, leak repair and emergency response are coordinated by phone, with limited visibility of where they are or what they found.

Our solution

Benefits

  • A verified record of buried assets as networks expand across 307 city gas geographical areas (industry context) [18].
  • Geo-tagged asset data of the kind Jal Jeevan Mission already uses for monitoring, extended into operations and maintenance (industry example) [17].
  • One platform and field app across a multi-utility organisation or a municipal body that runs several networks.

Privacy & data security

  • Data involved: customer addresses and connection details, pipeline routes and valve locations, and crew positions.
  • Sensitive network layers: detailed pipeline and plant locations are shared only with authorised roles, with audit logs of access and export.
  • Customer data minimisation: network analysis uses connection identifiers and aggregated counts; personal details remain in the utility's customer system.

How a project runs

From first data to daily decisions

  1. 1

    Baseline and data audit

    Collect existing GIS layers, R-APDRP data, single line diagrams, asset registers and billing extracts. Assess coverage, accuracy and gaps by circle and division, and agree a data model and topology rules with the utility's IT and operations teams.

  2. 2

    Network digitisation and field survey

    Digitise and update feeders, transformers, poles and LT lines, then run door-to-door consumer indexing with the mobile survey app. Each record carries GPS position, photographs and the supplying pole, DT and feeder, checked on the device.

  3. 3

    Integration with metering and billing

    Link the indexed network with smart meter, DT meter, feeder meter and billing systems using meter and account identifiers. Resolve mismatches through targeted field validation so the consumer-to-feeder hierarchy is reliable for energy accounting.

  4. 4

    Energy audit and analytics

    Run feeder and DT level energy audits, map losses, and apply machine learning and hotspot analysis to prioritise inspections. Produce ranked work lists for loss reduction, load balancing and infrastructure upgrades.

  5. 5

    Operations dashboards and crew tracking

    Deploy WebGIS dashboards for outages, reliability and crew positions, and connect field apps so completed jobs update the map. Train utility staff to maintain the GIS as connections and the network change.

Data we work with

  • Utility asset registers and single line diagrams

    Provide the starting inventory of substations, feeders, transformers and switching points to be reconciled with field data.

  • R-APDRP and IPDS era GIS data

    Existing network and consumer layers in many urban towns that can be updated rather than rebuilt from scratch.

  • Smart meter, DT meter and feeder meter data (AMI)

    Interval consumption and energy flow readings that drive energy accounting, tamper detection and loss analytics.

  • Billing and consumer master data

    Account numbers, tariffs, sanctioned load and billed energy used to compute losses for each feeder and transformer.

  • Field survey records from the mobile app

    GPS positions, photographs and network links for each consumer and pole captured during indexing and validation.

  • High resolution satellite and drone imagery

    Base mapping for network digitisation, vegetation and encroachment along line corridors, and rooftop area assessment.

  • Outage logs and crew GPS data

    Fault events, restoration times and crew positions that feed reliability dashboards and dispatch decisions.

KPIs you can track

  • AT&C loss by feeder and by distribution transformer
  • Share of consumers correctly indexed to DT and feeder
  • Share of feeders and DTs with a complete monthly energy audit
  • Inspection hit rate for suspected theft or tamper cases
  • Average time from fault report to crew assignment
  • Feeder-wise SAIFI and SAIDI
  • Smart meter installations validated against GIS location
  • Line kilometres with vegetation risk assessed and cleared

Privacy & data security

How we keep your data private and secure

A distribution utility's GIS holds two kinds of sensitive data at once. The first is personal: the location of every household, its meter number, its consumption pattern and its payment behaviour. Interval consumption from a smart meter can show when a home is occupied, so it needs the same care as any other personal data. The second is operational: the layout of substations, feeders and control systems is part of critical infrastructure, and the power sector has its own cyber security framework administered by the Central Electricity Authority. GLOBEIR designs utility GIS so that consumer data is minimised and pseudonymised wherever possible, and so that network data stays in India under the utility's control.

Regulations we design for

  • Digital Personal Data Protection Act 2023: consumer location, account and consumption records and geotagged photographs about an identifiable individual are personal data (s.2(t)); consent must be free, specific, informed, unconditional and unambiguous and limited to the data needed for the purpose; the utility remains responsible for processors it engages under contract (s.8) [19].
  • DPDP Rules 2025: notified on 13 November 2025 with phased commencement; security, breach notification and data principal rights provisions apply after 18 months (around May 2027). Reasonable safeguards include encryption or masking, access control, logging and backups; breaches must be reported to the Data Protection Board, with a detailed report within 72 hours [20].
  • CEA (Cyber Security in Power Sector) Guidelines 2021: mandatory for responsible entities in the power sector. They require hard isolation of OT systems from internet-facing IT systems, ISO/IEC 27001 certification of the responsible entity with sector controls under ISO/IEC 27019, a designated CISO, retention of logs for at least six months, sourcing of critical ICT equipment from trusted sources and reporting of cyber incidents in CERT-In formats [12].
  • CSIRT-Power and sectoral CERTs: the Ministry of Power set up CSIRT-Power at CEA on 5 April 2023 as an extended arm of CERT-In, with a dedicated sub-sectoral CERT for distribution; draft CEA Cyber Security Regulations 2025 were under finalisation as of December 2025, and audits are carried out by CERT-In empanelled auditors [13].
  • RDSS smart metering bid documents: the Standard Bidding Document for smart metering covers communication security, cloud security, cyber incident management and compliance with the DPDP Act [2].
  • CERT-In Directions (28 April 2022): report listed cyber incidents, including data breaches and unauthorised access, to CERT-In within 6 hours, and keep ICT system logs for a rolling 180 days within Indian jurisdiction [21].
  • DST Guidelines on Geospatial Data (2021): finer-than-threshold maps must be created and owned by Indian entities and stored and processed in India [22]; a 2022 DST clarification adds that such data must never reach servers of any non-Indian entity [23].
  • MeitY GI Cloud (MeghRaj) guidelines: advisory procurement guidelines for government cloud, with all data processing within India, relevant for State-owned DISCOMs [24].

Frequently asked questions

Why does a DISCOM need consumer indexing if it already has smart meters?

A smart meter tells the utility how much a consumer used, but not which transformer and feeder supplied that energy unless the link is recorded. Consumer indexing ties each meter to its pole, DT and feeder. Without that hierarchy, transformer and feeder level energy audits produce misleading loss figures, and loss reduction work is directed at the wrong places.

Can existing R-APDRP GIS data be reused?

Usually yes. Many urban towns were mapped under R-APDRP, which required consumer indexing and asset mapping of the network at and below 11 kV. That data is often outdated, so GLOBEIR can audit it, correct topology, update changed areas through field validation and extend coverage to rural and newly added areas instead of starting from zero.

How does GIS help with RDSS outcomes?

RDSS links grant release to AT&C loss and ACS-ARR performance and calls for automated feeder and DT level energy accounting. A connected network GIS with indexed consumers is what lets meter data be rolled up into credible feeder and transformer audits, so utilities can find losses, target works and report progress with evidence.

What does the field survey involve, and how is quality controlled?

Surveyors use a mobile GIS app to record each connection's GPS position, meter details, photographs and supplying pole and transformer. The app checks entries against the network map and mandatory fields before upload. Supervisors review records on a dashboard, and a sample is re-verified in the field so errors are corrected before the data is used for billing or audit.

Can GIS help DISCOMs plan for rooftop solar under PM Surya Ghar?

Yes. By mapping rooftops and existing solar connections against feeders and transformers, a utility can see where distributed generation is concentrating, which DTs may face reverse power flow or voltage issues, and where network upgrades or metering changes will be needed as more households install systems.
