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 — a major container port in Malaysia — 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 are large, supporting rooftop solar systems sized per site (Solar ATAP is capped at 1,000 kWac, with capacity capped at 100% of MD, which is not an MD charge reduction). The grid connection and medium voltage feeders to individual industrial plots are confirmed with TNB during the feasibility study, and Solar ATAP export applications are processed through standard TNB channels.

Cold Storage & Logistics: The High-Energy Profile

Cold chain facilities at PIIP are high energy-intensity operations. Refrigerated warehouses running continuous compressor loads consume large volumes of electricity depending 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.

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 BESS can reduce MD charges, which solar alone does not reliably do; the saving depends on your load profile. Explore our BESS solutions page for more detail.

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 system is commissioned and the application submitted to MGTC by 31 December 2026, and the entity is the tax-paying owner of the solar system.

For an illustrative 300 kWp system at RM 720,000 capex (RM2,400/kWp before SST), the 60% GITA provides RM 432,000 in tax allowance (worth up to RM 103,680 at a 24% tax rate if fully absorbed). Combined with annual savings of approximately RM 113,000 at the MV General energy rate, the post-GITA payback is about 5.5 years (about 6.4 years before GITA).
