Wattey monitors what a business pulls from the grid, Solar Performance Cloud monitors what its solar generates, and TenantBill handles multi-tenant billing. All three run real factories, solar plants, and shopping malls today — about 3 megawatts and growing. **Canonical URL:** https://alioahmed.com/work/bijli-bachao **Role:** Head of Product & Platforms — October 2025 – present **Summary:** Ali Ahmed designed, built, and runs Bijli Bachao’s three live IoT energy platforms — Wattey, Solar Performance Cloud, TenantBill — to IEC standards. ## Key figures - **3** — production platforms live - **~1.04 GWh** — grid energy monitored by Wattey - **56 sites** — solar plants on Solar Performance Cloud - **74 tenants** — billed through TenantBill at one mall BijliBachao.pk is Pakistan’s solar and energy-automation company, founded by Engr. Reyyan Niaz Khan — UET Lahore, 14+ years in Pakistan’s energy sector, and a pioneer of digital energy auditing in the country. Ali built the full platform stack for his company: one role, three platforms, one energy lifecycle. ### The three platforms - **Wattey — real-time IoT electricity monitoring** — 22 smart meters live across 8 client sectors — hotels, textile, paper, dairy, malls — with ~1.04 GWh monitored since January 2026. Three-minute live refresh, Pakistan-specific seasonal time-of-use tariffs, automatic generator detection, and solar import/export tracking. - ~500,000+ data points stored — voltage, current, power, energy, per phase - 459 kW highest peak load recorded at a single site - Multi-tenant dashboard: clients see only their own sites, 4 user roles - **Solar Performance Cloud — independent multi-brand solar monitoring** — Pakistan’s first independent multi-brand solar performance platform: 56 sites, 70 inverters, and 698 PV strings tracked individually across 5 brands (Huawei, Solis, Growatt, Sungrow, Canadian Solar) — 785 MWh tracked, 3.7 million+ readings, no hardware required. - Every string graded daily to the IEC 61724-1 performance-availability split - Fault diagnosis that names the issue: dust, shading, dead panel, sensor fault - Caught a 50% generation loss on one rooftop and a 33% loss at a mall the owner never knew about - **TenantBill by Wattey — photo-verified OCR billing** — Live at Mall of Muridke: 74 tenants, 469 meters, and 545 shops across 8 floor categories, every reading photo-verified and extracted by OCR at 85–95% confidence in under 2 seconds. A monthly billing cycle that took 15 days now takes 3 hours. - Month-close with frozen snapshots and a full audit trail - 95% error reduction, 80% faster invoicing, 70% fewer tenant complaints - 3 weeks from signed contract to live operation ### How it’s built — the engineering moat All three platforms share the same discipline, applied to Pakistani energy software from day one: - International standards: IEC 61724-1 health scoring and IEC 62446-1 five-state string classification — what utility-scale operators use globally. - Multi-tenant SaaS architecture with org-scoped data isolation and role-based access control, the way enterprise buyers expect SaaS to be built. - An observability baseline — error tracking, hourly system-health audits, health endpoints — plus enterprise-readiness audits across the suite. - Operator-handover discipline: runbooks, audit reports, and change logs, so the software is maintainable by any competent operator, not dependent on its builder. ### Who runs on it These are the platforms’ production clients — real Pakistani businesses: Lahore Continental Hotel, Mall of Mureedkay, Al Haram Paper Mill, FANZ Mills, Amna Dyeing & Finishing, Qadir Engineering, Zahoor Dairy Farm, and commercial sites in Gulberg, Lahore. Ali is the builder and Head of Product; operations stay with the BijliBachao team. ## FAQ ### Are the Bijli Bachao platforms actually live? Yes — all three run in production today. Wattey has monitored ~1.04 GWh across 22 smart meters since January 2026, Solar Performance Cloud tracks 56 solar sites with 3.7 million+ readings, and TenantBill generates real invoices at Mall of Muridke every month. ### What standards are they built to? Solar Performance Cloud ships IEC 61724-1 performance-availability health scoring and IEC 62446-1 five-state string classification — the international engineering standards used by utility-scale solar operators — and all three platforms share multi-tenant, role-based enterprise SaaS architecture. ### What is Ali Ahmed’s role at Bijli Bachao? Head of Product & Platforms, since October 2025. He designed and built the three platforms and the company website; BijliBachao was founded by Engr. Reyyan Niaz Khan, and daily operations stay with the BijliBachao team. --- Rendered from the structured content at https://alioahmed.com/work/bijli-bachao.
