Kulim Hi-Tech Park: Why Semiconductor Factories Suit Solar

Kulim Hi-Tech Park (KHTP) was established in 1996 as a dedicated hi-tech industrial zone — purpose-built to attract high-value advanced manufacturing that required exceptional infrastructure, stable power supply, and proximity to a skilled technical workforce. Today, KHTP is located in Kulim, Kedah, hosting semiconductor, photovoltaic, power-electronics and optoelectronics manufacturers.

What makes KHTP attractive for solar is the combination of three factors: very large single-storey factory footprints, a northern Peninsular location with irradiance confirmed per site, and the high electricity consumption intensity of semiconductor and electronics manufacturing.

Semiconductor Energy Profiles: Why Solar Is Especially Well-Suited

Semiconductor wafer fabrication is one of the most energy-intensive manufacturing processes. While KHTP's facilities are primarily back-end (assembly, test, and packaging) rather than front-end fabrication, they run continuous, high-baseload operations all year round. This continuous, predictable baseload is exactly what makes solar + BESS integration economically compelling:

• High self-consumption ratio: Because KHTP fabs never shut down, virtually all solar generation during daylight hours is immediately consumed — little export to grid, so output is valued at the full energy rate.
• Stable Maximum Demand profile: Unlike batch factories where MD spikes during production ramp-up, semiconductor operations maintain a near-flat demand curve. This means BESS can be sized for MD shaving specifically, not general load smoothing.
• Critical power requirements drive BESS sizing: Cleanroom equipment requires uninterruptible power. Solar + BESS proposals for KHTP are designed with N+1 redundancy on non-critical building circuits, so that solar integration does not compromise production-critical power quality.
• Long remaining facility life: Most KHTP facilities have 25 to 40 years of remaining operational life — well beyond the 25-year solar system design life, ensuring full value capture.

Solar PV Manufacturers Installing Solar on Their Own Roofs

Solar PV manufacturers are among the sectors at KHTP. Export-oriented manufacturers have historically prioritised capex on production equipment over facilities infrastructure. This is changing rapidly as corporate sustainability mandates from US and European headquarters require Scope 2 emissions reductions.

For solar manufacturers at KHTP, the solar PV system installed on the manufacturer's own factory roof can qualify for the 60% Green Investment Tax Allowance regardless of what the facility produces, subject to MGTC verification. An illustrative 500 kWp system at RM 1.2 million capex (RM2,400/kWp before SST) generates a GITA allowance of RM 720,000 — worth up to RM 172,800 in tax at the 24% corporate rate if fully absorbed, reducing effective cost to RM 1,027,200. At about RM 187,900 in annual electricity savings (MV General energy rate, all output used on site), post-GITA payback is about 5.5 years.

Solar Irradiance at Kulim: Confirmed Per Site

Annual irradiance at Kulim is confirmed per site during the feasibility study. Our illustrative savings use the same 3.5 peak sun hours for every site, so no irradiance advantage over other parks is counted in the estimate.

During the Northeast Monsoon season (November to March), peninsular east coast states experience heavy rainfall and cloud cover. Kulim is on the west side of the peninsula and is generally less exposed to this, although seasonal yield variation still applies.

Grid Supply at KHTP: Confirmed With TNB Per Site

KHTP is reported to be served by a dedicated TNB 275kV/33kV substation. Supply voltage and power quality are confirmed with TNB for each site, and our modelled yield does not assume any inverter-efficiency or clipping benefit from the grid supply.
