What determines whether a large-scale solar project is commercially viable in Malaysia?

What We Know

#### 1. Route to market

A project needs a lawful and financeable means of selling or using its electricity. Current routes include:

• Large Scale Solar competitive procurement;
• CRESS arrangements with corporate green consumers;
• self-consumption and rooftop programmes;
• eligible renewable-energy programmes;
• utility or isolated-system procurement.

The Energy Commission administers LSS through competitive bidding for developers to construct, own and operate plants in Peninsular Malaysia. Energy Commission LSS programme

An attractive site without an award, customer or other route to market is an opportunity—not yet a viable project.

#### 2. Electricity price and contract

The project must produce electricity below its contracted revenue after accounting for:

• construction;
• land;
• grid connection;
• operating costs;
• degradation;
• financing;
• taxes;
• insurance;
• curtailment;
• decommissioning;
• development and contingency.

Contract tenure, indexation, delay provisions, termination rights and offtaker credit are as important as the headline tariff.

#### 3. Grid connection

Commercial viability depends on:

• available capacity at the proposed connection point;
• required connection voltage;
• distance and route to the substation;
• network reinforcement;
• power-system studies;
• loss allocation;
• curtailment risk;
• delivery schedule for grid works.

The Energy Commission’s LSS connection guidelines establish the development and network-connection process for prospective plants. LSS connection guidelines

#### 4. Solar resource and energy yield

The financial model should use site-specific irradiation, temperature, shading, soiling, rainfall and flooding information. Yield assumptions should include:

• module degradation;
• inverter and transformer losses;
• cable losses;
• mismatch;
• clipping;
• availability;
• scheduled outages;
• grid unavailability.

#### 5. Suitable and controllable land

The project needs sufficient contiguous land with:

• secure tenure for the full project life;
• appropriate title and permitted use;
• manageable terrain;
• suitable access;
• acceptable drainage and flood risk;
• limited shading;
• no unresolved encumbrances;
• feasible cable and transmission routes.

#### 6. Capital and financing

Solar economics depend on interest rates, gearing, debt tenure, currency exposure, sponsor strength and lender confidence. Imported equipment can create foreign-exchange and delivery risk.

#### 7. Construction and supply chain

The project must manage:

• module and inverter selection;
• equipment availability;
• warranty strength;
• civil and electrical contractor capability;
• interconnection equipment;
• construction weather;
• local-content or participation requirements;
• commissioning schedule.

#### 8. Storage obligations or opportunities

BESS may improve firming or grid integration but adds cost, losses and degradation. It should be included where regulation, connection requirements or incremental project value justify it—not automatically.

#### 9. Environmental and social acceptability

Planning, drainage, erosion, glare, biodiversity, community impacts and decommissioning can affect approval, cost and schedule.
