// ROI: 3.5–4.5 YRS | POST-GITA: ~2.8 YRS
Pulau Indah's unique position — Malaysia's designated halal manufacturing zone adjacent to Port Klang — creates a diverse mix of food-grade, cold chain and heavy logistics operations with excellent solar economics.
Nestle, Fonterra, Dutch Lady
Food-grade factories with large flat rooftops. Two-shift operations. High daytime baseload matches solar yield perfectly.
DHL Cold Chain, Yusen Logistics
Continuous refrigeration load. BESS + solar combination cuts MD spikes during inbound cargo offloading shifts.
Westports service vendors
Warehousing and cargo processing. Large single-storey rooftops ideal for high-density panel installations.
PETRONAS downstream, Vopak
Tank farms and chemical storage facilities. Solar on office and utility buildings captures significant savings.
Various SME manufacturers
Smaller factories with moderate energy needs. Best fit for fully self-consumed NEM CAS configurations.
Large-footprint logistics and food manufacturing facilities make PIIP one of Selangor's highest per-site yield parks.
Estimated savings: RM250K–500K/yr
Estimated savings: RM120K–250K/yr
Estimated savings: RM80K–120K/yr
Pulau Indah Industrial Park occupies a purpose-reclaimed island in the Port Klang area, directly adjacent to Westports — Malaysia's busiest container port with over 13 million TEUs handled annually. The park is accessible via the dedicated Pulau Indah Expressway connecting to the North Port and South Port terminals.
As Malaysia's premier Halal Industrial Park Zone (HIPZ), PIIP attracts food & beverage manufacturers requiring halal certification, cold chain logistics operators, and port-support industries. The consistently high daytime occupancy and two-shift food manufacturing cycles create ideal conditions for solar self-consumption.
Average peak sun hours at PIIP: 4.9–5.3 hours/day. Grid voltage: 33kV Medium Voltage via dedicated PIIP substation.

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 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. Explore our BESS solutions page for detailed cold chain case studies.
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.
