How to use this dossier: Diffusion Engineers is a listed, promoter-led welding consumables and heavy-engineering group with four MSEDCL HT plants in Nagpur plus a Nov 2025 greenfield line — not a single-campus chemical complex. Stamped wins here by speaking electrode baking-oven idle hold, wire-drawing and flux-cored line MD overlap, open-arc wear-plate baseload, and Nimji CNC/fabrication startup sequencing on the MSEDCL bill. Read §2 (MSEDCL) and §3.1 (process loads) before picking a champion. Campaign revenue anchor ₹278 Cr FY24; latest FY25 ₹316 Cr and 9M FY26 ₹265 Cr. Legal name Diffusion Engineers Limited; NSE DIFFNKG, BSE 544264, CIN L99999MH2000PLC124154.

1. Company overview & snapshot

1.1 Legal identity & corporate structure

Promoter group: Garg family — founded by Mr. N. K. Garg (1982). Current leadership:

Professional management (post-IPO):

Shareholding / capital: IPO raised ₹145 Cr equity (Oct 2024). Paid-up capital ₹37.43 Cr [IPO DRHP]; face value ₹10. Net worth ₹369 Cr as on 31 Mar 2025 (CRISIL). Gearing 0.06× — low leverage, strong balance sheet.

Charges / debt: Bank facilities ₹65 Cr (CC ₹47 Cr, BG ₹13 Cr, LC ₹5 Cr); utilisation ~27% through Aug 2025. No debt-funded capex planned (CRISIL outlook).

Related entities (group map — do not confuse billing entity):

Former names / CIN history: Two previous CINs per aggregators — current L99999MH2000PLC124154 is authoritative.

1.2 What they make & where money comes from

Diffusion Engineers manufactures special-purpose welding consumables, wear plates and wear parts, and heavy engineering equipment, plus job-work welding/reconditioning services for cement, steel, power, mining, sugar, defence, oil & gas, and engineering sectors.

Product families (IPO DRHP + investor PPT FY25):

End markets: 84+ established clients; 503+ customers historically; 30+ export countries (USA, UAE, China, South Korea, Bangladesh, Kenya, Tanzania, Sri Lanka, Indonesia, Germany, etc.). 95 domestic distributors + 9 overseas distributors. Top 10 customers 25–30% of revenue (CRISIL FY25).

Capacity & throughput:

Revenue trajectory:

Competitive position: Mid-cap Indian specialist in hard-facing and special electrodes — competes with Ador Welding, ESAB India, Mailam India, local unorganised rod makers. Differentiation: backward integration (flux-cored wire → wear plates), DSIR R&D lab, NABL ISO 17025 testing, heavy-engineering fabrication at Nimji, SME100 brand, defence/railway order wins.

Raw material exposure: Steel and ferro-alloys 55–65% of operating revenue (CRISIL); powdered metals (Cr, Ni, Mo, Mn); volatility compresses margin between 11.8–14.9% over five fiscals.

1.3 Plants, addresses & footprint

Important: Investor presentation unit numbering differs from current website contact page. Use website mapping for outreach; reconcile on first call.

Manufacturing plants (all Nagpur district, MSEDCL territory):

Investor PPT alternate numbering (legacy — crosswalk):

Non-manufacturing / sales:

Contact phones (verified):

Emails (verified patterns):

Recommended pilot site: Unit III (N-78/N-79 Hingna) — largest Hingna lease campus (13k sq.m), flux-cored wire + wear-plate lines (continuous thermal loads), dedicated maintenance leadership on LinkedIn, separate phone/email channel. Secondary: Unit IV Nimji if HT meter is cleaner on heavy-engineering bay (higher MD, 1.1 MW solar interconnection complexity).

1.4 Leadership & CRM map

Tier 0 — Board & promoters (economic / policy)

Tier 1 — Operations & plant maintenance (champion hunting)

Gap: No public Head of Electrical, Plant Head, or VP Operations title found on LinkedIn or website. Champion hunt must go through maintenance manager tier → CEO → CFO. [!] Pradeep Kumar Singh LinkedIn hit is different company (textile plant) — do not use.

Tier 2 — Sales / BD (not first call)

Decision path for 90-day pilot:

1. Technical champion: Manojkumar Kolhe (maintenance) + Sagar Bagade (electrical) — bill pain + machine/oven access.
2. Production ally: Ravi Pancheshwar or unnamed Unit III production head [TBD].
3. Plant P&L sponsor: Ramesh Kumar N (CEO) — cross-unit ops since Feb 2025.
4. Commercial: Abhishek Mehta (CFO) — ₹2–5L proof-run fee; receptive if ₹ savings clear on MSEDCL bill.
5. MD escalation: Prashant Garg only if pilot proves ₹20L+/month line item or ties to IPO solar ROI narrative.

1.5 Recent news (24 months) & timing for Stamped

Outreach timing: Now (Q1 FY27 / Aug 2026) — post Nov 2025 new line stabilisation; before monsoon maintenance shutdown (Jul–Sep [~]). Avoid Mar year-end audit freeze if possible.

2. Energy profile

DISCOM / supply: Maharashtra State Electricity Distribution Co. Ltd. (MSEDCL) for all Nagpur plants (Hingna MIDC + Nimji/Khapri rural industrial feeders). Not Tata Power Nagpur franchise in MIDC industrial estates — verify exact circle/division on bill header (e.g. Hingna / Nagpur Urban / Rural).

2.1 Bill band, tariff & demand

Reported energy posture (AR FY25 + concall May 2025):

Electricity consumption estimate [~] (no BRSR published — listed SME transition):

ICP gate: Pass — conservative bottom ₹40L/month exceeds ₹30L HT minimum; likely ₹60L–1 Cr with Nimji heavy engineering.

MSEDCL HT Industrial tariff (5th control period, MERC MYT Order 28 Mar 2025, Case 217/2024):

CMD/MD hypothesis [~]:

Multi-feeder risk: Each MIDC plot likely has separate HT connections — MD penalties multiply if electrode ovens and wire lines start simultaneously across units in Slot 4. Stamped value: cross-unit stagger awareness even without central EMS.

Penalty exposure: PF <0.95, MD exceedance after new line commissioning, ToD slot-4 oven preheat, demand ratchet post-expansion.

2.2 Generation, fuel & renewables

Solar interaction with Stamped: Solar reduces energy charge but not necessarily MD — Stamped still valuable for MD/ToD/idle optimisation; position as complementary not competing with IPO solar capex.

2.3 EnMS, PAT, ISO, BRSR

Quality policy energy line (website): “Intensify efforts in conservation of key natural resources like petroleum products, electricity, water and wood.”

2.4 Likely ₹ leak categories (hypothesis)

3. Operations, equipment & digital stack

3.1 Process flow & critical loads

A. Special-purpose electrode manufacturing (Unit I + Proposed Facility):

1. Wire rod preparation — cleaning, straightening
2. Dry mix / flux preparation — blending minerals, ferro-alloys
3. Extrusion coating — wire through flux extruder 15–40 kW
4. Baking/drying oven — 200–400°C tunnel or batch ovens 100–500 kW equivalent → dominant thermal load
5. Cooling & inspection — conveyors, NDT
6. Packaging

B. Flux-cored wire (Unit III + Unit IV):

1. Strip forming from steel coil
2. Powder fill — mineral flux core
3. Closing/forming rolls — 30–80 kW drives
4. Multi-pass wire drawing — 50–200 kW cumulative per line
5. Annealing — electric furnace 50–150 kW
6. Spooling & packaging

C. Wear plate / wear parts (Unit III + IV):

1. Steel plate preparation — cutting, bevelling
2. Open-arc or SAW hard-facing — 300–800 A arcs — high instantaneous load; often dedicated transformers
3. Stress relief / slow cool — optional furnace
4. Machining/finishing — CNC/plasma

D. Heavy engineering (Unit IV Nimji):

1. Fabrication — welding, plate rolling
2. CNC machining — VMC, lathe, boring 20–100 kW each
3. Assembly — cranes, hydro tests
4. Paint shop — blowers, ovens

Specific energy benchmarks (industry [~]):

Critical loads ranked by kWh + MD impact:

1. Electrode baking ovens (Units I + Proposed)
2. Wire drawing blocks (Unit III/IV)
3. Open-arc / SAW cladding stations
4. Nimji CNC/machine shop
5. Annealing furnaces
6. Compressed air
7. Flux mixing motors
8. HVAC / lighting (minor)

3.2 Shifts, seasonality, production pattern

3.3 Automation, metering, SCADA/EMS/DCS

Named vendors: Siemens CNC, Fanuc [LinkedIn skills on Kolhe]; no public EMS vendor.

3.4 Capex / tech projects affecting energy

4. Stamped Energy fit analysis

4.1 ICP scorecard

4.2 Fit score rationale

Fit score: 9/10

−1 point: No named Head of Electrical/Plant Head; revenue-per-employee high may mean smaller absolute kWh than revenue suggests; geography outside core belt.

4.3 Wedge (parser-critical)

The strongest wedge is: Unit III Hingna (N-78/79) flux-cored wire and wear-plate oven/drawing idle-load verification on the MSEDCL HT bill — read-only on existing meters, assigning baking-oven hold and wire-line startup MD leaks to specific lines in ₹/month, proven on the next invoice within 90 days, without PLC writes or capex.

4.4 Objections & competitors

4.5 Pilot design

5. Before you reach out

5.1 Discovery checklist

• Confirm legal entity on MSEDCL bill matches Diffusion Engineers Limited
• Obtain 12 months HT bills per unit (Unit III first)
• Count HT connections — separate vs pooled across Hingna plots
• Verify billed MD vs connected load per unit
• Map sub-meter coverage on oven mains and wire drawers
• Identify shift pattern and ToD slot utilisation
• Confirm Proposed Facility on separate meter (Nov 2025)
• Ask about 1.1 MW Nimji solar — commissioned? net-metering arrangement?
• Route: Manoj Kolhe → Ramesh Kumar N → Abhishek Mehta
• Reconcile Unit numbering (website vs old PPT)
• Validate email manoj.kolhe@diffusionengineers.com before send
• Check defence/railway order rush — production schedule impact

5.2 Do not lead with

• Do not lead with dashboards, AI buzzwords, or ESG-first pitch
• Do not cite obsolete revenue ₹278 Cr without noting FY25 ₹316 Cr growth
• Do not promise to replace solar IPO capex — complement it
• Do not confuse with Diffusion Software or other “Diffusion” brands
• Do not contact Pradeep Kumar Singh (wrong company on LinkedIn search)
• Do not lead with Hurun family business ranking — sounds like flattery

5.3 Opening hooks (email / call / WhatsApp)

Email hook: “Four Nagpur plants — I’d verify electrode oven idle hold and wire-line MD overlap on your MSEDCL bill before you commission more baking capacity at Hingna.”

Call hook: “Unit III N-78 is the obvious first feeder: flux-cored wire plus wear-plate thermal lines, separate phone line, and your maintenance team on LinkedIn — we prove ₹ on the next MSEDCL invoice in 90 days, read-only.”

6. Risks, flags, controversies & sources

6.1 Integrity / controversy / regulatory (search explicitly)

Searches conducted (Aug 2026): "Diffusion Engineers" fraud; "Diffusion Engineers" NGT; "Diffusion Engineers" PCB; "Diffusion Engineers" lawsuit; "Diffusion Engineers" labour; "Diffusion Engineers" SEBI penalty; promoter Garg controversy.

Conclusion: Clean public profile suitable for outbound.

6.2 Data quality flags

• Unit numbering differs between investor PPT and website — reconcile on call.
• Revenue figures vary: ₹257 Cr company-only vs ₹278 Cr consolidated FY24 in DRHP — use ₹316 Cr FY25 for current sizing.
• Employee count LinkedIn 150–200 vs likely 400–600 [~] with shop-floor — verify AR.
• No BRSR energy tables yet — all kWh figures are [~] estimates.
• Manoj Kolhe email inferred — not verified.
• Pradeep Kumar Singh false positive on LinkedIn — exclude.

Appendix A — MSEDCL deep reference (Nagpur / Hingna industrial)

A.1 DISCOM territory confirmation

MIDC Hingna Industrial Area (Nagpur) and Uma Khapri / Nimji (Kalmeshwar road, Nagpur rural) are served by MSEDCL. Nagpur city has some SNDL (Sponge Iron & Steel … [verify] — actually SNDL is separate franchise in parts of Nagpur; MIDC industrial estates typically remain MSEDCL HT). Confirm on bill header — expect Maharashtra State Electricity Distribution Co. Ltd.

A.2 HT Industrial tariff structure (FY25-26 baseline)

Per MERC MYT Order (Case 217/2024), HT I (A) HT-Industry:

Worked example — Unit III N-78/79 [~]:

• Billed MD: 2,000 kVA
• Demand charge: 2,000 × ₹555 = ₹11.1L/month
• Energy: 400,000 kWh × ₹7.5 = ₹30.0L/month
• Total ≈ ₹41L/month (before FAC, taxes, penalties)

If 10% oven idle-load reduction saves 40,000 kWh: ₹3.0L/month energy + possible 150 kVA MD reduction → ₹0.83L/month demand = ₹3.8L/month ≈ ₹46L/year.

A.3 ToD optimisation playbook for electrode/wire plants

A.4 Power factor & harmonics

Wire drawing VFDs and CNC drives create harmonics. Verify:

• PF on bill >0.95 lagging
• No reactive penalty line items
• Capacitor bank maintenance logs

A.5 Nagpur-specific notes

• Central India grid — summer peak (Apr–Jun) high ambient → oven losses ↑
• Monsoon (Jun–Sep) — humidity affects flux drying time → longer oven residence
• Winter (Nov–Feb) — lower cooling load on Nimji shop

Appendix B — Electrode manufacturing energy engineering

B.1 Baking oven thermodynamics

Tunnel oven typical profile:

[Feed] → [Pre-heat zone 150°C] → [Dry zone 250°C] → [Bake zone 350-400°C] → [Cool] → [Outfeed]
         20-40 kW/zone              40-80 kW/zone       80-200 kW/zone

Idle hold leak:

• Oven on standby between batches: 40–60% of full-run thermal input to maintain wall temperature
• If 2 tunnel ovens idle 45 min/shift unnecessary: 2 × 80 kW × 0.75 h × 2 shifts × 26 days = 6,240 kWh/month ≈ ₹47,000/month [~] per oven pair

B.2 Extrusion coating line

Extruder motor 15–40 kW — runs only during coating; lower idle risk than oven.

B.3 Prescription examples Stamped would generate

1. “Oven O-2: reduce soak setpoint 15°C in job gap — est. ₹28,000/month”
2. “Line E-4: schedule batch start 06:15 not 17:30 — est. ₹19,000/month ToD”
3. “Drawing block DB-3: stagger start with DB-2 — est. ₹45,000/month MD”

Appendix C — Flux-cored wire line energy

C.1 Process energy map

[Decoil] → [Forming rolls] → [Fill] → [Close] → [Draw blocks ×4-8] → [Anneal] → [Spool]
  5 kW        30-50 kW         10 kW    20 kW      50-200 kW total    50-150 kW

C.2 Drawing block MD model

Scenario: 4 blocks × 45 kW start within 10 minutes:

• Simultaneous inrush + steady ≈ 180 kW → 189 kVA at 0.95 PF
• If 3 lines start together on same HT point: 567 kVA spike

Stagger 8 minutes apart: peak ~189 kVA — 67% MD reduction on startup window.

C.3 Annealing furnace

Batch annealing 50–150 kW — cycle 2–4 hours. Leaving furnace on between small batches = classic idle hold.

Appendix D — Wear plate open-arc / SAW cladding

D.1 Arc load characteristics

Open-arc welding 300–800 A at 30–40 V = 9–32 kW per arc — but duty cycle matters:

• Active arc: high load
• Positioning/idling: 10–25 kW transformer/motor standby

D.2 Multi-station overlap

3 cladding stations idling between plates: 3 × 15 kW × 0.4 h × 16 h/day × 26 days = 74,880 kWh/month [~] if poorly managed.

D.3 Prescription angle

“SAW-2: inter-pass delay timer → auto transformer tap down — est. ₹52,000/month”

Appendix E — Nimji heavy engineering / CNC energy

E.1 Machine shop loads

E.2 Morning startup sequence

Nimji likely 08:00–08:30 machine starts for defence/cement orders — uncoordinated = MD spike on rural feeder.

E.3 Solar 1.1 MW interaction

Stamped value post-solar: maximise self-consumption + MD/ToD still open.

Appendix F — Compressed air & utilities

F.1 Typical CA system

F.2 Flux pneumatic handling

Pneumatic flux transfer — leaks cause continuous unload cycles.

Target: 8–12% CA electricity — ₹8–15L/year group [~].

Appendix G — Champion hunting playbook (Diffusion-specific)

G.1 Primary target profile

G.2 Secondary targets

G.3 Email pattern hypotheses

G.4 Phone routing

G.5 LinkedIn DM sequence

1. Day 0: Connect with note — “Nagpur electrode/wire plant — MSEDCL bill question”
2. Day 3: DM if accepted — WhatsApp script from kit
3. Day 7: Email to inferred address + info@ fallback

Appendix H — Group structure & billing entities

H.1 Consolidation for energy sales

Bill likely issued to Diffusion Engineers Limited for all Nagpur plants — subsidiaries are trading/services, not separate industrial HT [~].

H.2 Subsidiary energy (out of scope for pilot)

Appendix I — IPO objects & capex energy impact

I.1 IPO use of proceeds (DRHP summary)

I.2 Energy implication

New capacity without sequencing discipline = higher MD ratchet for 12 months post-commissioning.

Appendix J — Competitive landscape (welding consumables)

Appendix K — Customer segment energy linkage

Stamped angle: Diffusion’s own Nagpur plant bill — not customer sites.

Appendix L — Raw material / margin / energy nexus

Steel 55–65% of revenue → margin 11.8–14.9% band → every 1% electricity save ≈ 0.1–0.15% EBITDA margin [~] at ₹316 Cr revenue:

• 10% bill save on ₹80L/month = ₹96L/yr ≈ 30 bps EBITDA — meaningful to CFO.

Appendix M — Financial snapshot tables

M.1 Quarterly performance (₹ Mn)

*Excluding other income

M.2 Balance sheet highlights (31 Mar 2025)

Appendix N — Plant-by-plant energy estimate detail

Appendix O — Shift & production pattern detail

Appendix P — Metering & SCADA entry paths

P.1 Path A — MSEDCL AMR + HT bill

• Monthly bill PDF + AMR interval data if available
• Stamped correlates MD events to production log

P.2 Path B — Sub-meter retrofit

P.3 Path C — PLC read-only

Siemens/Fanuc CNC — OPC read if IT allows VLAN.

Appendix S — MSEDCL consumer onboarding checklist

• Consumer numbers all units
• Sanctioned load letters
• Single-line diagrams Unit III
• Oven/kW nameplate list
• Drawing block motor specs
• Last energy audit if any
• Solar net-meter agreement Nimji
• Shift roster

Appendix T — Electrode oven types reference

Appendix U — Flux chemistry & mixing energy

Flux mixing motors 5–20 kW — often left running during breaks. Low-hanging fruit for shift SOP.

Appendix V — Defence & railway order implications

HVF flux-cored wire order (May 2025 MD letter) → quality runs may resist oven setback — pitch MD/ToD not temperature reduction on qualified batches.

Appendix W — Export vs domestic mix

Export 30+ countries — may run night shifts for container loading → ToD Slot 4 exposure.

Appendix X — R&D lab Unit I (DSIR)

R&D oven tests small batch — separate from production ovens; exclude from pilot scope unless shared HT.

Appendix Y — NABL lab electricity

Testing equipment intermittent — minor load; not pilot focus.

Appendix Z — Environmental compliance

ISO 14001 certified — environmental audits exist; energy data may be in EMS manual — request on discovery.

Appendix AA — NHAI land acquisition Unit IV

2018 NHAI acquisition ~3,191 sq.m — reduced campus; verify no feeder relocation affected HT point.

Appendix AB — Lease vs owned plants

Units I–III + Proposed on lease — long-term energy retrofit approval from landlord MIDC [~] usually straightforward for tenant improvements.

Appendix AC — Water-energy nexus

Flux preparation, cooling water for wire drawing — pump energy 5–10 kW continuous.

Appendix AD — DG set & backup power

Appendix AE — Seasonality detail

Appendix AF — Order book execution energy

₹193 Cr backlog → high utilisation → fewer intentional shutdowns → idle hold leaks dominate over turn-off savings.

Appendix AG — ESOP 700,000 shares

Retention tool for maintenance talent — Kolhe may stay through pilot if ESOP eligible [~].

Appendix AH — Dividend policy signal

15% final dividend FY25 — cash-rich; not capital-constrained for ₹3–5L pilot.

Appendix AI — CRISIL rating sensitivities

Downside if cash accruals <₹25 Cr — energy save supports upside sensitivity (>₹55 Cr accruals).

Appendix AJ — Working capital & energy

GCA 310 days — efficiency improves margin without WC injection.

Appendix AK — Competitor Ador — PAT reference

Ador in PAT scheme — Diffusion not — no regulatory energy reporting obligation; less public energy data.

Appendix AL — Stamped deployment archetype match

Appendix AM — Pilot success metrics detail

Appendix AN — Rollout pricing [~]

Appendix AO — Travel & onsite logistics

Site visit: Day 1 Unit III meter map; Day 2 Unit IV Nimji if phase 2.

Appendix AP — Night shift & ToD analysis

If single-shift declared on MSEDCL — 40% MD discount possible [verify MERC schedule] — immediate trust-builder if misclassified.

Appendix AQ — Contract demand optimisation

If recorded MD never exceeds 70% of contract → recommend contract demand reduction with MSEDCL evidence from Stamped.

Appendix AR — Harmonic filter maintenance

No public harmonic filter install — VFDs on drawers may need PF correction audit.

Appendix AS — Integrated Management System (IMS)

ISO 9001/14001/45001 integrated — energy KPI could slot into management review if Stamped provides monthly ₹ ledger.

Appendix AT — Superconditioning services subsidiary

On-site customer work — not Nagpur plant load; exclude from pilot kWh baseline.

Appendix AU — LSN Diffusion UK JV

Powder metallurgy R&D — minimal Nagpur grid impact.

Appendix AV — Singapore export hub

Trading — not manufacturing HT.

Appendix AW — Heavy Vehicle Factory order

Defence flux-cored wire — prestige order — use as rapport, not primary energy hook.

Appendix AX — Cement HPGR opportunity

Company developing grinding rollers — future Nimji load growth; early EnMS embed wins long-term account.

Appendix AY — Indian Railways / Nuclear push

Management targeting new sectors — new product lines = new oven/drawing profiles = ongoing Stamped value.

Appendix AZ — LinkedIn hiring signals

Company LinkedIn active — growth hiring BDE, engineers. No energy manager hire — gap for Stamped as outsourced intelligence.

Appendix BA — Stock market context

NSE DIFFNKG — post-IPO performance strong; Q4 FY25 PAT margin 11.93%. Energy efficiency = margin expansion without steel price dependency.

Appendix BB — False champion exclusions

Appendix BC — Verified contact matrix

Appendix BD — GSTIN plant reconciliation

Single GSTIN 27AAACD8008L1ZK on all contact blocks — likely single legal entity billing all units.

Appendix BE — MIDC Hingna industrial cluster context

Neighbouring units: engineering, fabrication, auto components — typical 11 kV/33 kV HT supply pattern.

Appendix BF — Nimji rural feeder characteristics

Rural industrial feeders sometimes have lower reliability — DG test frequency may be higher; verify AMF settings.

Appendix BG — Cold repair compounds line

Polymer/ceramic mixing — lower thermal than electrodes; minor pilot scope.

Appendix BH — Trading segment energy

Thermal spray powder trading — warehouse only; minimal kWh.

Appendix BI — Job-work welding service

In-house job shop at plants — arc loads intermittent; sub-meter if significant.

Appendix BJ — Investor relations routing

For CFO approach: BSE/NSE filings portal + info@ → Company Secretary Chanchal Jaiswal.

Appendix BK — Ferro-alloy & powder handling energy

Ferro-chrome, ferro-manganese, nickel powder, and molybdenum additives are handled in closed or ventilated bays at Unit I and Unit III. Material handling includes:

Leak pattern: Baghouse and blender motors left running through 30-min tea breaks between electrode SKU changeovers. At Unit I with 2 blenders × 18 kW × 0.5 h × 2 breaks × 2 shifts × 26 days = 3,744 kWh/month ≈ ₹28,000/month [~].

Stamped prescription format: “Blender BL-1: interlock with batch timer — auto stop at T+45 min if no load — est. ₹28,000/month.”

Appendix BL — Electrode quality vs energy trade-off

Diffusion’s special-purpose electrodes (defence, nuclear-adjacent, high-alloy) require tight baking curves. Maintenance will resist oven setback on qualified SKUs — correct objection handling:

Lead with scheduling and MD on all SKUs; offer thermal setback only where QA confirms no hydrogen pick-up risk.

Appendix BM — Wear plate backward integration energy chain

Investor narrative emphasises backward integration: flux-cored wire production feeds open-arc wear-plate cladding in-house. Energy flows across Unit III:

[Steel coil] → [FCW line — Appendix C] → [Wire spool to cladding] → [Open-arc deposit — Appendix D] → [Finished plate]

Cross-process leak: FCW line stops but cladding stations keep arc transformers energised waiting for next spool — 15–25 kW transformer idle each × 4 stations = significant baseload.

Pilot meter map suggestion: HT main → Oven feeder A → Drawing block bus → Cladding transformer bus → Compressor main.

Appendix BN — MSEDCL Nagpur circle / division lookup guide

On first HT bill, capture these fields for Stamped onboarding:

Expected division names [~]: Nagpur Rural, Hingna, or Nagpur Urban — all under MSEDCL post-merger structure.

Appendix BO — MERC regulatory calendar (2025–26)

Do not quote pre-Apr 2025 tariff rates on discovery calls — verify against actual Mar–Jun 2026 bills.

Appendix BP — Staggered startup simulation (Unit III wire drawing)

Scenario: 3 flux-cored wire lines, each with 6 drawing blocks × 40 kW, all started 08:00–08:20:

If contract demand 800 kVA → 30% exceedance penalty on incremental MD [~].

Stagger 12 minutes per line: peak ~522 kVA — within contract.

Stamped product: automated stagger schedule to shift supervisor WhatsApp with rupee penalty forecast.

Appendix BQ — Baking oven zone-wise setback protocol (SOP draft for discovery)

Proposed maintenance SOP Stamped would validate:

Measurement: Thermocouple log + HT main kW drop correlated — M&V for MSEDCL bill match.

Appendix BR — Nimji 1.1 MW solar technical parameters [~]

Stamped + solar stack: (1) maximise self-consumption by shifting non-critical loads to 10:00–15:00; (2) reduce MD before solar commissioning so ratchet baseline lower.

Appendix BS — Comparison to Stamped deployment peer set

Diffusion is only SME100 Tier A in campaign with electrode baking as primary thermal load — differentiate messaging from plastics/metals peers.

Appendix BT — Promoter engagement path (Prashant Garg)

Use only after technical pilot proof or if maintenance gate blocked:

Do not cold-email MD — route through Kolhe → CEO → MD.

Appendix BU — CFO commercial close (Abhishek Mehta)

Appendix BV — CEO operational sponsor (Ramesh Kumar N)

Appointed Feb 2025 — likely building professional ops layer over promoter shop-floor culture. Energy efficiency win = early CEO credibility metric.

Concall quote (May 2025): started monitoring energy consumption — CEO already has energy KPI on radar. Stamped = execution layer for his monitoring initiative.

Appendix BW — Unit numbering reconciliation script (call use)

Read to maintenance on first call:

“Your website lists Unit II at T-12 and Unit III at N-78/79, but your May 2025 investor deck labels N-78 as Unit II. We don’t care about the label — we care which HT consumer number covers the flux-cored wire and wear-plate ovens. Can you confirm?”

Appendix CB — WhatsApp message variants (BeHuman sweep)

Variant A (technical):

Manoj — Utso, Stamped Energy. We read your HT meter data only, find oven idle and morning MD leaks in rupees, verify on next MSEDCL bill. No PLC changes. Worth 15 min on Unit III N-78?

Variant B (post-expansion):

Manoj — with the new Hingna line and Nimji solar coming up, morning startup overlap on MSEDCL MD is the first thing I’d check. We do that read-only and prove savings on the bill. Quick call?
