On-Site Solar vs CRESS vs GET vs RECs: A Corporate Renewable-Energy Buyer’s Guide

By: Progressture Solar | Last verified: 29 July 2026

There is no single “best” Malaysian renewable-electricity product. On-site solar changes a site’s physical generation and imported electricity; CRESS is a direct procurement framework that enables eligible Green Consumers in Peninsular Malaysia to source renewable electricity from a developer through open access to the grid; GET is TNB’s tariff subscription with bundled Malaysia RECs; and standalone RECs are contractual environmental-attribute instruments whose quality and claims depend on their issuance, retirement and your reporting rules. Buyers should select a portfolio based on load, site control, contract appetite, desired claims, supply term and evidence—not on marketing labels alone.

At a glance: what are you buying?

Option • What changes physically? • Contract/evidence core • Best initial fit • Major caution

On-site solar (SELCO/other applicable route) • PV generation at/for the site; load consumes it first under the applicable programme/design. • Asset/EPC or PPA/lease; interconnection and programme documentation; production and import/export metering. • Sites with suitable roof/land, daytime load and control of premises. • SELCO says excess is not allowed to be exported; confirm the applicable programme, sizing and approvals.

CRESS • Remote/new green-energy plant energy is wheeled through the electricity supply network; the utility remains supplier of last resort. • Bilateral Energy Supply Contract, CRESA and related NEDA/system-access arrangements. • Large/strategic buyer seeking a longer-term direct renewable-energy contract and able to manage process risk. • CRESS is not a simple tariff add-on; grid studies, contracts, SAC and delivery/imbalance risks matter.

GET • Grid supply stays grid supply; buyer subscribes to a green tariff product. • GET agreement, subscription/billing and mREC issued after calendar year-end. • Buyers needing a relatively accessible green-electricity subscription without installing solar. • Quota/terms are subject to review; buyer cannot choose renewable source in bundled mREC programme.

RECs • No direct change to a buyer’s physical electricity flow. • Credible certificate issuance, ownership transfer and retirement/cancellation record matched to use period and reporting boundary. • Residual electricity after operational solutions, or sites unable to use other options. • A purchase is not proof of physical delivery to the site and should not be double-counted or over-claimed.

Option 1: On-site solar—when physical self-generation is the priority

SEDA describes SELCO as electricity generated for own usage, with excess not allowed to be exported to the grid. For a buyer, on-site solar can reduce imported energy when production and consumption coincide. It may also create an operational asset, lease/PPA relationship or rooftop-use agreement depending on procurement model.

Ask before choosing it

• Do we control the roof/land and have a lease term that supports the project?

• What is our daytime interval load and what percentage of solar output can we use on site?

• Is SELCO, Solar ATAP or another current route applicable to this customer/site?

• Who owns the asset, carries performance risk and captures any relevant incentive?

• How will curtailment/export, metering, maintenance, fire safety and end-of-term removal be handled?

Option 2: CRESS—when a direct grid-access renewable contract is worth the complexity

The Energy Commission’s current CRESS guideline describes direct procurement from a Green Energy Plant owned by a Renewable Energy Developer to a Green Consumer via the electricity supply network in Peninsular Malaysia. CRESS uses the NEDA framework; the developer develops/owns/operates a new plant, energy is wheeled subject to System Access Charge (SAC), and the utility remains supplier of last resort where the developer cannot generate and supply.

CRESS due-diligence questions

• Are our premise, demand arrangement and new/additional-demand position eligible under the current guideline and utility requirements?

• What are the proposed PPA/Bilateral Energy Supply Contract price, term, volume shape, indexation, credit support and termination rights?

• What do power-system studies, connection, SAC, balancing/imbalance, curtailment and congestion assumptions do to the economics?

• How are renewable certificates allocated, retired and evidenced? The guideline addresses RECs, but the contract must make ownership/retirement unambiguous.

• What happens when the plant under-produces, the grid is constrained, or our consumption changes?

Option 3: GET—when simplicity and bundled certificates are the priority

TNB says GET lets consumers purchase low-carbon electricity supply without installing their own solar/RE installation. GET customers pay the normal applicable tariff plus a GET subscription charge, and receive Malaysia Renewable Energy Certificates (mRECs) after the end of the calendar year. TNB says the customer cannot select the renewable-energy source in this bundled mREC programme.

Current official product details to recheck before publication or subscription

• GET is offered to TNB consumers; non-domestic blocks are 1,000 kWh minimum and subscription can be up to 130% of average monthly consumption, subject to TNB conditions and quota.

• The cited TNB page states 1 July 2025 premium rates of 5 sen/kWh (one year), 4 sen/kWh (two years), 3 sen/kWh (three years) and notes terms/quota can change.

• GET’s Greenpath programme addresses qualifying tenant-account arrangements and states an additional 0.2 sen/kWh administration/operational charge.

Use these figures only after live re-verification; they are product terms, not a financial recommendation.

Option 4: RECs—when the environmental attribute is the product

A REC is not an electron-delivery contract. It is evidence associated with renewable electricity attributes, so its usefulness depends on programme rules and credible issuance, ownership transfer and retirement/cancellation. GET is one route to bundled mRECs; a corporate may also encounter other REC offerings. Before making a Scope 2, “renewable electricity” or “100% renewable” statement, align with the applicable reporting standard, client requirements and certificate programme rules.

REC controls checklist

• Specify the certificate programme, generation country/location, technology, vintage and volume.

• Obtain serialised issuance/transfer/retirement evidence and retire once only for the claimed period.

• Establish who owns certificates under a PPA, CRESS or solar lease; do not assume the electricity buyer automatically does.

• Avoid using the same MWh for more than one claim or multiple entities.

• Have sustainability/legal reviewers approve the exact public claim and reporting boundary.

A decision path for CFOs, sustainability teams and operations

1. Start with load and sites: interval consumption, peak demand, roof/land, tenancy and future load changes.

2. Set the objective: cost exposure, resilience, operational decarbonisation, renewable-electricity claims, or a mix.

3. Model on-site solar first where viable: it is the most direct physical intervention but depends on site/load match.

4. Assess CRESS for strategic scale/term: obtain a realistic grid and contractual risk model—not just a PPA headline price.

5. Use GET for a simpler TNB-account option: verify live quota, pricing and certificate timing.

6. Use RECs with claims discipline: buy only with a retirement and disclosure plan.

7. Build a portfolio: on-site generation plus a grid product/certificates may be more suitable than trying to force one option across every site.

GET quota, premium, AFA treatment and terms can change. Do not claim any option makes electricity “physically 100% renewable” at all times, guarantees Scope 2 treatment, or makes a REC claim valid without a certificate retirement and reporting review.
