Shah Alam
Seksyen 15/16

Shah Alam has been the backbone of Malaysia's manufacturing economy since the 1970s industrialisation drive. Seksyen 15 and 16 represent the city's original heavy industrial zones — where household brand names in food, automotive, and consumer electronics first established their Malaysian operations. This industrial heritage means the zone has fully depreciated buildings, stable grid infrastructure, and most importantly, factory owners who are ready to deploy capital into energy rather than structure upgrades.

Today the zone houses facilities spanning food and beverage processing, automotive components, consumer electronics assembly, and cold storage distribution. Factory rooftops in Seksyen 15 typically suit 100 to 250 kWp rooftop solar systems that deliver strong self-consumption without oversizing relative to the load (Solar ATAP is capped at 1,000 kWac, with capacity capped at 100% of MD, which is not an MD charge reduction).

The Port Klang Logistics Angle

Shah Alam's position 25 km from Port Klang (Westports and Northports) makes it a natural hub for import-dependent manufacturers and export-oriented consumer goods producers. Several large logistics and distribution centres have established operations in Seksyen 15 and adjacent sections specifically to serve the port corridor — and these facilities carry large roof areas and high energy profiles.

A typical logistics distribution centre in Seksyen 15 with a large single-storey warehouse can install a 150–200 kWp rooftop system, generating approximately 189,000–252,000 kWh annually. At the Medium Voltage General energy rate (RM0.2983/kWh), this offsets about RM 56,000–75,000 in annual electricity spend, if all output is used on site. Maximum demand savings are not counted.

Selangor TNB Tariff Context

Industrial consumers in Shah Alam are typically supplied at 33kV and billed under TNB's Medium Voltage General or Medium Voltage Time of Use tariff (these replaced the old E1/E2 tariffs on 1 July 2025). The maximum demand charge on MV General is RM 89.27 per kW per month under RP4 (RM 97.06 on MV ToU peak-period demand), and the MV General energy charge is RM 0.2983/kWh. For a typical F&B factory with a 400 kW MD reading, the monthly MD bill alone exceeds RM 35,700 — so maximum demand is checked separately from your own bills when sizing solar.

Illustrative Scenario: 150 kWp F&B Factory, Seksyen 15

A food manufacturing facility running two daily shifts (6am–10pm), installs a 150 kWp rooftop system comprising about 242 Jinko 620 W panels on aluminium sub-frames. Annual yield: approximately 189,000 kWh (3.5 peak sun-hours). If all output is used on site, annual savings at the Medium Voltage General energy rate (RM0.2983/kWh) are approximately RM 56,400. Indicative price: RM 360,000 plus SST (RM2,400/kWp); a Low Voltage site at RM0.5068/kWh would save about RM 95,800 a year. Pre-GITA payback: about 6.4 years. With 60% GITA applied (RM 51,840 of tax value if fully absorbed at a 24% tax rate): effective post-GITA payback of about 5.5 years. This is an illustrative scenario, not a Trexon project.
