Six-Month Energy Pattern

Feb–Jun 2026 from the supplied monthly extract, plus the Jul 2026 billing statement. Average draw is ~57,430 KWH per month (≈689 MWH annually).

Reading: Fixed Charge is Rs. 566,250 — a large standing cost that signals a substantial sanctioned load. The all-in effective rate (~48.5 PKR/unit) is dominated by taxes and surcharges layered on the ~23.5 PKR energy component.
03 — Demand & MDI

Maximum Demand Position

Demand charges are driven by Maximum Demand Indicator (MDI). Solar that covers the daytime peak trims MDI.

ItemValue
Baseline MDI (Jun 2026)440 kW
Sanctioned load (from FIX-CHRG)≈ 566 kW
Post-solar MDI (applied factor)396 kW
MDI reduction≈ 10%
Baseline MDI uses the latest printed record (Jun 2026, 440 kW); the Jul 2026 extract did not print MDI. Sanctioned load is derived from the Rs. 566,250 fixed charge (~Rs. 1,000/kW·month).
Client-provided assumption: after solar installation, MDI reduces to 90% of the pre-solar value. This is applied as a planning factor based on experience from a comparable pharmaceutical installation. The post-solar MDI of 396 kW is therefore a planning estimate, not a measured result.
  • Why it matters: lower MDI reduces the fixed/demand portion of every future bill, independent of the energy saving.
  • To confirm: supply the printed MDI figure from the Jul 2026 statement so the baseline can be fixed exactly.
04 — Solar PV Proposal

Recommended Self-Consumption System

Sized to the annual consumption, assuming all generation is self-consumed (zero export) — the conservative, hardware-only base case.

System Size
~393 kWp
≈ 546 × Trina Vertex N 720W modules
Annual Generation
~689 MWh
at Punjab PSH 4.8, net yield
Self-Consumption
~95%
generation < consumption ⇒ minimal export
Sizing logic: Annual consumption ≈ 689,156 KWH. At Punjab Performance Ratio / peak-sun 4.8, required capacity = 689,156 ÷ (4.8 × 365) ≈ 393 kWp. Because projected generation stays at or below consumption, the zero-export base case holds: every solar unit displaces an imported unit rather than being sold back.
  • No solar currently installed — this is a greenfield proposal for the account.
  • Modules: Trina Vertex N 720W (N-type TOPCon, bifacial) — high yield per string, suitable for industrial roofs/ground-mount.
  • Configuration: string inverters sized to the load profile, with a zero-export controller if export is not permitted by the distributor.
05 — Financial Case

Savings & Payback (Base Case)

Base case = solar hardware only. Regulatory levers (tax waivers, tariff changes) are excluded and shown separately as conditional upside.

MetricValue
Energy displaced / year≈ 654,400 KWH
Saving @ energy rate (23.5)Rs. 15.4 M / yr
Saving @ variable rate (38.2)Rs. 25.0 M / yr
Indicative capex (@ ~Rs.130/Wp)Rs. 51.1 M
Simple payback (low / high)3.3 yr / 2.0 yr
Capex is an indicative all-in turnkey figure for planning; a firm quotation is required. Saving range reflects the rate basis (energy-only vs. variable).

Conditional Upside subject to approval

  • Sales-Tax registration → potential E-Tax + F-Tax waiver (~Rs. 0.49 M on the Jul bill alone).
  • MDI / Fixed-Charge revision → further reduction beyond the 90% solar effect.
  • DG-capacity enhancement → headroom for future load.
  • Fixed export tariff → only if export is permitted by the distributor.
None of the above is assumed in the base-case payback. Each is "Subject to LESCO approval / tax-advisor confirmation / interconnection review."
06 — Basis & Next Steps

Assumptions & Open Items

Working Assumptions

  • Consumption: 6-month actuals (Feb–Jul 2026); annualised linearly.
  • PV yield: Punjab peak-sun 4.8, net of system losses.
  • Self-consumption 95%; zero export assumed (generation ≤ consumption).
  • Post-solar MDI = 90% of baseline (client-provided factor).
  • No solar currently installed on site.

To Finalise the Proposal

  • Confirm the printed MDI on the Jul 2026 statement.
  • Confirm export policy — zero-export or net-metered.
  • Roof / ground area & orientation survey for layout.
  • Firm turnkey quotation to replace the indicative capex.
Bottom line: A ~393 kWp self-consumption system offsets nearly the entire annual energy draw, delivering an indicative Rs. 15–25 M/year saving and a ~2–3 year payback on hardware-only economics — before any conditional regulatory upside.
