Pulau Indah
Industrial Park

Pulau Indah Industrial Park (PIIP) occupies a purpose-reclaimed island in the Klang Strait, connected to the Selangor mainland via the dedicated Pulau Indah Expressway. Adjacent to Westports — Malaysia's busiest container port handling over 13 million TEUs annually — PIIP has evolved into two complementary zones: the halal-certified Halal Industrial Park Zone (HIPZ)hosting food and pharmaceutical manufacturers, and the Port Klang Free Zone (PKFZ) serving transhipment, bonded logistics, and export-processing tenants.

Factory sizes at PIIP are generally larger than the Klang Valley average. Single-storey logistics and food processing facilities range from 8,000 to 30,000 m², supporting 200 to 500 kWp rooftop solar systems. The dedicated 132kV/33kV Pulau Indah substation provides stable grid supply with medium voltage feeders to individual industrial plots, ensuring that NEM CAS net-metering applications process through standard TNB channels without the complications seen at some older industrial zones.

Cold Storage & Logistics: The High-Energy Profile

Cold chain facilities at PIIP represent some of the highest energy intensity operations in Malaysia. Refrigerated warehouses running continuous compressor loads consume 800,000 to 3,000,000 kWh per monthdepending on temperature zone and throughput. Unlike standard manufacturing operations, cold chain facilities run 24 hours a day — meaning solar generation only directly covers the daytime portion of consumption, typically 40–60% of total daily load.

This is precisely where a Solar + BESS (Battery Energy Storage System) combination delivers superior economics. Excess solar generation during midday peak hours charges the BESS; that stored energy discharges during early-morning and evening peak-demand windows — the hours when cold chain compressors spike the TNB maximum demand reading. By capping the MD reading, a 300 kWp solar system paired with a 300 kWh BESS can reduce MD charges by 25–35% beyond what solar alone achieves.

GITA for Free Industrial Zone Companies

Companies operating within the Port Klang Free Zone are sometimes uncertain about GITA eligibility given their FIZ tax status. The key determinant is whether the entity pays Malaysian corporate income tax on domestic income — many PKFZ operators do, particularly those with both domestic and export sales streams. GITA applies to qualifying solar capex regardless of FIZ status, provided the installation is commissioned before 31 December 2026 and the entity is the tax-paying owner of the solar system.

For a 300 kWp system at approximately RM 900,000 capex, the 60% GITA provides RM 540,000 in tax allowance. Combined with annual savings of approximately RM 250,000–300,000, the post-tax payback compresses to under 2.8 years — one of the strongest ROI cases in Selangor.
