Malaysia’s Large-Scale Solar (LSS) program is the primary route for developers to build utility-scale solar farms and sell power to Tenaga Nasional Berhad (TNB) under a long-term Power Purchase Agreement. Unlike NEM 3.0 — which serves self-consumption customers — LSS is a competitive tender where developers bid on price. The lowest viable bids win. This guide covers the LSS program structure, tender history, eligibility, bid preparation, PPA terms, and the full project timeline from announcement to energisation.
LSS Is Not a Self-Consumption Scheme
LSS is designed for independent power producers selling electricity to TNB — not for factories or commercial buildings that want to reduce their own electricity bill. If you are a C&I buyer seeking solar for self-consumption, use NEM 3.0 or SELCO instead. LSS requires a generation licence, competitive bidding, and a 21-year PPA commitment. The regulatory complexity and capital requirement are an order of magnitude higher than rooftop NEM.
What Is the LSS Program?
The Large-Scale Solar (LSS) program was introduced by the Malaysian government to diversify the national energy mix and meet renewable energy targets under the Malaysia Renewable Energy Roadmap. LSS projects are ground-mounted or large rooftop solar farms that generate electricity for sale into the TNB grid — not for on-site consumption.
Key characteristics of LSS:
- Competitive bidding: Developers submit sealed bids with a proposed tariff (RM/kWh). The Energy Commission evaluates bids on price and technical merit.
- Fixed PPA price: The winning bid tariff is locked for 21 years with no escalation clause.
- TNB offtake: TNB purchases all generated electricity at the bid tariff under a standard-form PPA.
- Grid connection: Projects must connect to TNB’s transmission or distribution network at a technically feasible point.
- Development timeline: Winning bidders typically have 24–36 months from award to commercial operation date (COD).
LSS complements Malaysia’s other solar pathways:
| Pathway | System Size | Purpose | Revenue Model |
|---|---|---|---|
| NEM 3.0 | Domestic ≤12 kWp; Non-domestic ≤75% MD | Self-consumption with grid export | Bill offset (1:1 credit) |
| SELCO | Any size (within TNB limits) | Self-consumption only | Bill offset (no export) |
| LSS | >1 MW (tender-based) | Utility-scale generation for grid sale | PPA revenue from TNB |
LSS Tender Round History
Malaysia has run multiple LSS tender rounds since the program’s inception. Each round specifies the total capacity to be allocated, minimum project size, and any technology or location preferences.
Historical Tender Rounds
| Round | Year | Capacity Allocated | Notable Features |
|---|---|---|---|
| LSS 1 | 2016–2017 | 500 MW | First competitive solar tender in Malaysia |
| LSS 2 | 2017–2018 | 563 MW | Increased competition; tariffs declined |
| LSS 3 | 2019–2020 | ~1,000 MW | Larger round; more stringent technical criteria |
| LSS 4 | 2021–2022 | ~1,000 MW | Included floating solar and agrivoltaic categories |
| LSS 5 | 2023–2024 | ~2,000 MW | Largest round to date; accelerated timeline |
Tariff Trends
LSS tariffs have fallen sharply as competition intensified and technology costs declined:
| Period | Typical Winning Tariff Range |
|---|---|
| LSS 1 (2016) | RM 0.28–0.39/kWh |
| LSS 2 (2017) | RM 0.20–0.30/kWh |
| LSS 3 (2019) | RM 0.18–0.25/kWh |
| LSS 4 (2021) | RM 0.16–0.22/kWh |
| LSS 5 (2023–2024) | RM 0.15–0.20/kWh |
The downward trajectory reflects global module price declines, improved financing terms, and aggressive bidding by developers seeking market share. Bidders today must model costs precisely — margins are thin and underbidding can render a project unbankable.
Who Can Participate in LSS Tenders?
Eligibility Requirements
LSS tenders are open to companies and consortiums that meet the Energy Commission’s qualification criteria:
- Malaysian-registered company: The bidding entity must be incorporated in Malaysia. Foreign companies may participate through joint ventures with Malaysian partners.
- Technical capability: Demonstrated experience in solar project development, construction, or operation. The Energy Commission may require evidence of past projects or technical partnerships.
- Financial capacity: Proof of financial strength — typically through audited financial statements, bank references, or letters of support from financial institutions.
- Land control: Evidence of land access — either ownership, lease agreement, or letter of intent from the landowner. The land must have suitable solar resource and grid access.
- Equity requirement: Bidders must commit a minimum equity contribution (typically 20–30% of project cost) and demonstrate the ability to raise debt financing for the remainder.
Consortium Bidding
Many LSS bids are submitted by consortiums that combine:
- A local Malaysian partner (land access, regulatory knowledge, local relationships)
- An international developer or EPC contractor (technical expertise, equipment procurement)
- A financial investor (equity capital, project finance relationships)
The consortium agreement must define each party’s role, equity split, and decision-making authority. The Energy Commission evaluates the consortium’s combined capability as a single bidding entity.
The LSS Bidding Process
Step 1: Tender Announcement
The Energy Commission publishes a tender notice on st.gov.my specifying:
- Total capacity to be allocated (MW)
- Minimum and maximum project size per bid
- Application deadline
- Bid bond amount and format
- Evaluation criteria (price weighting, technical score)
- Any special categories (floating solar, agrivoltaic, BIPV)
Register on the Energy Commission website for email notifications of new tender rounds.
Step 2: Pre-Bid Preparation
Before submitting a bid, developers must:
- Secure land: Identify and secure land with suitable solar irradiance (4.5–5.5 PSH), flat or gently sloping terrain, and proximity to TNB grid infrastructure.
- Conduct feasibility study: Assess grid connection feasibility, environmental impact, and land use restrictions.
- Form bidding entity: Establish the Malaysian-registered company or consortium that will submit the bid.
- Arrange financing: Secure indicative financing terms from banks or financial institutions.
- Prepare technical design: Develop a preliminary engineering design including array layout, inverter configuration, and grid connection design.
Step 3: Bid Submission
The bid submission typically includes:
| Document | Purpose |
|---|---|
| Technical proposal | System design, equipment specifications, construction plan |
| Financial proposal | Bid tariff (RM/kWh), financial model, funding plan |
| Environmental Impact Assessment (EIA) | Compliance with Department of Environment requirements |
| Land documents | Proof of ownership, lease, or land use agreement |
| Company credentials | Registration documents, financial statements, past project experience |
| Bid bond | Bank guarantee or cash deposit (typically 1–2% of project value) |
Late submissions are rejected. Incomplete submissions may be disqualified or scored lower.
Step 4: Bid Evaluation
The Energy Commission evaluates bids using a weighted scoring system. Typical weightings:
- Price (tariff bid): 60–70% of total score
- Technical merit: 20–30% (design quality, experience, track record)
- Local content / other criteria: 10–20% (Malaysian participation, technology innovation)
The lowest tariff does not always win — a bid with a very low tariff but weak technical credentials may be rejected if the evaluator determines the tariff is not credible or the project is not deliverable.
Step 5: Award and PPA Negotiation
Winning bidders receive a Letter of Award from the Energy Commission. The next steps:
- Sign PPA with TNB: Negotiate and execute the standard-form Power Purchase Agreement. The PPA term is 21 years at the bid tariff.
- Obtain generation licence: Apply to the Energy Commission for a generation licence under the Electricity Supply Act 1990.
- Achieve financial close: Secure final project financing and satisfy lender conditions precedent.
- Commence construction: Begin engineering, procurement, and construction (EPC) within the timeline specified in the PPA.
Bidding Strategy: Model Costs Before Setting Tariff
The most common mistake in LSS bidding is setting a tariff based on competitor behaviour rather than project-specific costs. Build a detailed financial model that includes: module and inverter costs (with shipping and duties), EPC costs, land lease, grid connection costs, financing costs, O&M over 21 years, and contingency. Add a minimum equity return hurdle (typically 10–12% IRR) and solve for the tariff that meets it. Only then compare with market benchmarks. A bid that wins but cannot be financed wastes 18 months of development effort.
PPA Terms and Structure
The LSS PPA is a standard-form agreement between the project company and TNB. Key terms include:
Tariff and Payment
- Fixed tariff: The bid tariff applies for the full 21-year term with no annual escalation.
- Payment mechanism: TNB pays for all metered generation (kWh) at the tariff rate.
- Billing cycle: Monthly invoicing based on TNB meter readings.
- Currency: Ringgit Malaysia (RM).
Commercial Operation Date (COD)
- Target COD: Typically 24–36 months from PPA execution.
- Liquidated damages: Delayed COD may trigger liquidated damages payable to TNB.
- Early COD: Projects may achieve COD early if construction finishes ahead of schedule.
Performance Obligations
- Availability requirement: The plant must maintain a minimum availability factor (typically 80–85%).
- Degradation allowance: Module degradation is factored into the expected output profile.
- Force majeure: Defined events (natural disasters, grid failure beyond project control) excuse non-performance.
Termination
- TNB termination: TNB may terminate for persistent non-performance, failure to achieve COD, or insolvency.
- Developer termination: Limited — typically only for persistent TNB payment default or grid unavailability.
- Early termination compensation: Calculated based on outstanding debt and equity return.
LSS Project Timeline
The full LSS lifecycle from tender announcement to commercial operation:
| Phase | Duration | Key Milestones |
|---|---|---|
| Tender announcement and bidding | 3–6 months | Tender published; bids prepared and submitted |
| Bid evaluation and award | 2–4 months | Technical and financial evaluation; Letter of Award issued |
| Financial close and land acquisition | 6–12 months | PPA signed; financing secured; land formalised |
| Construction (EPC) | 12–18 months | Engineering, procurement, construction; grid connection built |
| Commissioning and COD | 2–3 months | TNB inspection; performance tests; PPA activation |
Total timeline: 24–36 months from tender announcement to COD for a typical ground-mounted project. Floating solar or complex grid connections may extend this.
Financing LSS Projects
LSS projects are typically financed through project finance structures:
- Debt-to-equity ratio: Typically 70:30 to 80:20
- Debt tenor: 15–18 years (shorter than the 21-year PPA)
- Interest rate: Based on Malaysian reference rates plus margin
- Security package: PPA cash flows, project assets, land rights, and sponsor guarantees
Lenders conduct detailed due diligence on:
- PPA bankability (tariff sufficiency, TNB credit risk)
- EPC contractor track record
- Technology risk (module degradation, inverter reliability)
- Grid connection feasibility
- Environmental and social compliance
Land and Grid Connection Considerations
Land Requirements
- Size: Approximately 2–2.5 hectares per MW for ground-mounted systems
- Terrain: Flat or gently sloping; avoid flood-prone areas
- Land use: Must be permissible for solar under local planning regulations
- Access: Road access for construction and O&M vehicles
- Grid proximity: Within economically viable distance of TNB substation or transmission line
Grid Connection
- Voltage level: Typically 33 kV or 132 kV depending on project size and grid capacity
- Connection cost: Borne by the developer; can be significant for remote sites
- Grid impact study: TNB conducts a grid impact study to assess the effect of the solar injection on the local network
- Timeline: Grid connection approvals can take 6–12 months; start early in the development process
Environmental and Social Compliance
LSS projects require:
- Environmental Impact Assessment (EIA): For projects above certain size thresholds, a full EIA is required by the Department of Environment (DOE).
- Social impact assessment: For projects affecting local communities, particularly on agricultural land.
- Permits: Planning permission, land conversion (if agricultural), watercourse permits, and any other local approvals.
Environmental compliance is a bid evaluation criterion and a PPA condition. Projects that fail to secure environmental approvals risk PPA termination.

LSS vs NEM vs SELCO: Which Pathway?
For developers and investors deciding which Malaysian solar pathway to pursue:
| Factor | LSS | NEM 3.0 | SELCO |
|---|---|---|---|
| Project size | >1 MW | Domestic ≤12 kWp; Non-domestic ≤75% MD | Any size |
| Revenue model | PPA with TNB | Bill offset (1:1 credit) | Bill offset (no export) |
| Regulatory route | Energy Commission tender | SEDA quota + TNB connection | TNB connection only |
| Capital requirement | High (RM millions) | Low to moderate | Low to moderate |
| Development timeline | 24–36 months | 4–6 months | 2–4 months |
| Risk profile | Competitive bidding risk; long-term PPA commitment | Quota availability risk; straightforward | Lowest regulatory risk |
| Suitable for | Solar farm developers, IPPs, energy investors | Commercial building owners, factories | 24/7 operations with high self-consumption |
Choose LSS if: You are a developer or investor with access to land, capital, and project development expertise. You want to sell electricity to TNB as a business.
Choose NEM 3.0 if: You own or operate a commercial building and want to reduce your TNB bill through solar self-consumption and export credits.
Choose SELCO if: You have high 24/7 base load and want solar for self-consumption only, avoiding the SEDA quota process.

Common LSS Development Pitfalls
| Pitfall | Cause | Prevention |
|---|---|---|
| Underbidding and unbankable project | Tariff set below true cost to win bid | Build detailed cost model before bidding; set minimum IRR hurdle |
| Grid connection delay | Substation capacity constraints; remote site | Conduct grid feasibility study before bid submission |
| Land title issues | Agricultural land; unresolved ownership disputes | Secure clean land title or long-term lease before bidding |
| EIA rejection | Sensitive ecological area; community opposition | Conduct pre-application environmental screening |
| Financing failure | Weak sponsor balance sheet; non-bankable PPA terms | Secure indicative financing before bid; use experienced lenders |
| Construction delay | EPC contractor underperformance; equipment shortages | Engage proven EPC with track record; secure equipment early |

Frequently Asked Questions
Can a foreign company bid for LSS projects in Malaysia? Yes, foreign companies can participate in LSS tenders through joint ventures with Malaysian-registered partners. The bidding entity itself must be incorporated in Malaysia. Foreign ownership restrictions may apply depending on the tender round conditions — check the specific tender document for local content and equity requirements.
What happens if an LSS project fails to achieve COD on time? The PPA typically includes liquidated damages for delayed COD — a fixed amount per day of delay, capped at a maximum period. Persistent delay beyond the cap may trigger PPA termination. Developers should build contingency into construction schedules and secure EPC contracts with delay penalties that mirror the PPA liquidated damages.
Is the LSS tariff really fixed for 21 years with no escalation? Yes. The standard LSS PPA uses a fixed tariff with no annual escalation. This means the real value of the tariff erodes with inflation over time. Developers must model this erosion in their financial projections. Some developers have explored inflation-linked financing or hedging strategies to mitigate this risk.
Can LSS projects include battery storage? Battery storage is not a standard feature of LSS PPAs, but the Energy Commission has indicated openness to hybrid solar-plus-storage projects in recent tender rounds. Storage would require additional technical evaluation and may affect the bid tariff. Check the specific tender conditions for storage eligibility.
What is the difference between LSS and feed-in tariff (FiT) in Malaysia? Malaysia’s Renewable Energy Act 2011 originally introduced a feed-in tariff (FiT) mechanism where approved projects received a guaranteed tariff without competitive bidding. The FiT scheme has been largely replaced by competitive tender mechanisms (LSS for large projects, NEM for self-consumption). LSS projects compete on price; FiT projects received a fixed tariff set by the regulator. New FiT approvals are limited — LSS is now the primary route for utility-scale solar.
How does LSS interact with Malaysia’s renewable energy targets? LSS is a key mechanism for Malaysia to meet its renewable energy capacity targets under the Malaysia Renewable Energy Roadmap and Nationally Determined Contributions (NDC) under the Paris Agreement. The size and frequency of LSS tender rounds are calibrated to national target trajectories. Developers should monitor government policy announcements for signals on future round sizes and timelines.
