Pasir Gudang
Industrial Area

Pasir Gudang Industrial Area (PGIA) is a continuous heavy industrial corridor along the eastern Johor coastline. Established in the 1970s as a petrochemical and oleochemical hub anchored by Pasir Gudang Port, the zone today hosts major facilities spanning petrochemicals, oleochemicals, polymer processing, heavy engineering fabrication, and port-support logistics. The port provides direct sea access for raw material imports and finished goods exports.

Industrial tenants at PGIA are large energy consumers, running continuous petrochemical and oleochemical operations. This creates a fundamentally different solar economics case compared to lighter industrial parks: even a large 500 kWp or 1 MWp rooftop system covers only a small fraction of total site consumption — meaning every kWh generated is self-consumed at full tariff value with near-zero export waste.

Maximum Demand Management at PGIA

Under TNB's Medium Voltage General tariff, the maximum demand (MD) charge is RM 89.27 per kW per month (RP4, post-July 2025; RM 97.06 on MV ToU, RM 31.21–44.82 at high voltage). A heavy manufacturing facility on MV General with a 2,000 kW MD reading pays RM 178,540 per month in MD charges alone — before a single kWh of energy consumption is billed. Solar alone does not reliably cut MD, so peak-demand management (including BESS) is assessed separately from your own bills. An illustrative 1 MWp rooftop system generating about 1.26 million kWh annually saves approximately RM 376,000 a year in energy chargesat the MV General energy rate (RM0.2983/kWh), if all output is used on site. Payback is about 6.4 years at RM2,400/kWp before SST, or about 5.5 years after GITA (up to RM 345,600 of tax value at a 24% tax rate).

CBAM Compliance: Solar as an Export Competitiveness Tool

The EU Carbon Border Adjustment Mechanism (CBAM) — fully enforced from January 2026 — imposes carbon levies on exports of steel, aluminium, cement, fertilisers, electricity, and hydrogen into the EU market. PGIA manufacturers of these goods that export to the EU may be exposed. On-site renewable generation via solar PV reduces your Scope 2 emissions and ESG footprint. For CBAM, indirect (electricity) emissions count only for cement and fertilisers in the transition phase, so for steel and aluminium it does not change the CBAM figure. Whether CBAM applies depends on what your site produces.
