Buy physical green electricity directly from solar producers via the TNB grid. Malaysia's open access framework gives large corporations verified, location-based renewable energy for RE100 and ESG compliance.
The Corporate Renewable Energy Supply Scheme (CRESS) is Malaysia's open grid access framework that allows independent power producers to supply green electricity directly to corporate consumers via the TNB transmission network — without those consumers needing to own or operate any generation assets.
Unlike CGPP (which is a virtual, financial arrangement), CRESS involves physical electricity delivery. Green electrons generated by a solar farm are injected into the TNB grid and transmitted directly to your facility. The supply is physically traceable and certified as renewable.
This physical delivery model makes CRESS the most credible renewable energy procurement pathway in Malaysia — satisfying location-based Scope 2 reporting requirements under the GHG Protocol, and meeting the highest standard of RE100 qualification.
Unlike CGPP (financial settlement) or RECs (certificate-only), CRESS delivers actual green electricity to your meter via TNB open access.
Solar IPPs sell green electricity directly to corporates. TNB acts as the network operator — not the energy supplier under CRESS.
Physical delivery enables location-based Scope 2 accounting — more rigorous than market-based REC claims for international ESG auditors.
CRESS is governed by the Energy Commission under the Electricity Supply Act. Wheeling tariffs and access rights are regulated for fair corporate participation.
From solar farm generation to certified green electricity at your meter — CRESS uses TNB's existing grid infrastructure to deliver physical renewable electricity to large corporate consumers.
An independent solar power producer generates renewable electricity at a grid-connected solar farm and injects it into the TNB transmission network.
Electricity travels through TNB's open-access transmission infrastructure. Wheeling charges are applied for the use of the national grid.
Your facility receives certified green electricity — physically traceable renewable energy, not a virtual offset or financial settlement.
You receive two bills: the Independent Power Producer invoices for green electricity, TNB invoices for wheeling/distribution. Net cost is typically below standard TNB tariff.
Negotiated fixed rate for green electricity generated by the solar IPP. Typically lower than TNB retail tariff over the contract term.
Regulated transmission and distribution fee paid to TNB for transporting green electricity through the national grid to your facility.
CRESS total cost (IPP + wheeling) is structured to be below projected standard TNB tariff escalation over the contract term.
Three pathways to corporate renewable energy in Malaysia — physical delivery, virtual settlement, or on-site generation.
| Criteria | CRESS | CGPP (Virtual PPA) | Physical PPA |
|---|---|---|---|
| Electricity Delivery | Physical — via TNB grid | Virtual — financial settlement | Physical — on-site consumption |
| Roof or Premises Required | No — grid-delivered | No — remote solar farm | Yes — on your roof/premises |
| Scope 2 Reporting Method | Location-based (strongest) | Market-based (via RECs) | Location-based (on-site) |
| Contract Counterparty | IPP + TNB (wheeling) | Solar Power Producer | Solar service provider |
| Typical Contract Term | 10–21 years | 3–5 years | 10–20 years |
| Minimum Scale | 1 MW+ (HV-connected) | 1 MW+ | 50 kW+ |
CRESS = Corporate Renewable Energy Supply Scheme. CGPP = Corporate Green Power Programme. Physical PPA = on-site solar Power Purchase Agreement.
CRESS is designed for large corporate energy consumers — organisations with significant electricity demand and ESG commitments that require the most credible form of renewable energy procurement.
Manufacturing plants, data centres, and industrial parks connected to high-voltage TNB infrastructure with consistent high energy demand.
Facilities with peak demand exceeding 1 MW — typically connected to 132kV or above. Smaller consumers may aggregate demand across multiple sites.
Companies with science-based targets (SBTi), RE100 commitments, or investor ESG mandates requiring physically verifiable renewable energy procurement.
Multinational companies committed to 100% renewable electricity that need location-based Scope 2 reporting, the most credible RE100 compliance pathway.
GLCs and GLICs under government sustainability mandates who need auditable physical green electricity to support national Net Zero targets.
Malaysian manufacturers supplying to international brands (Apple, IKEA, Unilever) that require Scope 3 emissions disclosure from their supply chain partners.
Physical green electricity via open grid access — the most credible, scalable, and infrastructure-light pathway to 100% renewable energy in Malaysia.
Receive actual renewable electricity — not a certificate or financial offset. The strongest form of green energy procurement available in Malaysia.
Location-based Scope 2 reporting satisfies GHG Protocol, RE100, CDP, SBTi, and TCFD requirements. Internationally auditable and credible.
Physically displace grid electricity carbon intensity with verified zero-carbon solar generation directly attributed to your facility.
Lock in a fixed generation rate for 10–21 years, hedging against TNB tariff escalation and providing budget predictability for your energy costs.
CRESS is delivered via the TNB grid — no rooftop assessments, structural surveys, building management approvals, or on-site installation required.
CRESS can supply 100% of your facility's electricity demand from renewable sources — no partial coverage limitations unlike many on-site solar solutions.

Common questions from energy managers and sustainability leads evaluating physical green electricity procurement.
CRESS (Corporate Renewable Energy Supply Scheme) is an open grid access framework that allows corporate consumers to receive physical green electricity directly from independent solar power producers via the TNB transmission network. Unlike CGPP (Corporate Green Power Programme), which involves only financial settlement and virtual RECs, CRESS involves actual physical delivery of renewable electricity to the corporate consumer. Under CRESS, the green electrons physically flow from the solar farm through the grid to your facility.
Under CRESS, an independent power producer (IPP) generates solar electricity and injects it into the national grid. TNB facilitates open access — meaning the corporate consumer pays wheeling charges to transport that electricity through TNB's transmission infrastructure. The corporate consumer is then billed by both the IPP (for the green electricity) and TNB (for transmission and distribution services). The electricity received is certified as renewable, supporting location-based Scope 2 reporting under the GHG Protocol.
CRESS is designed for large energy consumers, typically those with peak demand exceeding 1 MW and connected to the high-voltage (132kV or above) transmission grid. Eligible consumers generally include large manufacturers, data centres, universities, and industrial parks. The Energy Commission sets specific eligibility criteria and these thresholds may be revised periodically. Trexon will assess your peak demand profile and advise on eligibility during initial consultation.
No major infrastructure changes to your building are required. Your existing TNB high-voltage connection remains in place. What changes is the billing and contractual arrangement — you will have a direct supply agreement with the CRESS-registered Independent Power Producer for the green electricity component, while TNB continues to charge for transmission, distribution, and any shortfall supply. The grid itself delivers the electricity seamlessly.
CRESS delivers physically traceable green electricity to your facility, enabling location-based Scope 2 reporting under the GHG Protocol — the most stringent form of renewable energy claim. This satisfies RE100's requirements for physical procurement, supports SBTi science-based targets, and provides verifiable evidence for CDP climate disclosures. Because the electricity is physically green (not just financially offset), CRESS claims are generally considered more robust than virtual PPA instruments by international sustainability auditors.
CRESS supply agreements are typically long-term contracts spanning 10 to 21 years, matching the operational life of the solar generation asset. Pricing is negotiated directly between the corporate consumer and the Independent Power Producer, with TNB wheeling tariffs regulated by the Energy Commission. The long-term fixed rate provides energy price certainty — a significant hedge against rising electricity tariffs. Trexon structures CRESS agreements to optimise the price spread between the agreed generation rate and projected TNB retail tariff escalation.
Trexon's corporate energy team will assess your demand profile, evaluate CRESS eligibility, and structure a physical renewable energy agreement tailored to your ESG targets.
