CRESS: Corporate Renewable Energy Supply Scheme

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.
