REG(E) carbon abatement cost and verification plan

A REG(E) carbon abatement case must connect engineering change, annual emissions reduction, qualifying cost and post-project verification. The Resource Efficiency Grant for Emissions supports eligible industrial projects with measurable and verifiable abatement, but an early estimate is not the same as a defensible project baseline. The company needs one model that engineering, finance and management can all trace.

Confirm the project sits within REG(E)

The current EDB REG(E) information sheet covers eligible manufacturing facilities and data centres in Singapore. It requires measurable and verifiable emissions reduction of at least 250 tonnes per year and states that support is based on abatement, subject to a cap on qualifying costs.

Record the applicant, site, current process, proposed equipment or system and emissions sources affected. If the project is mainly a building retrofit or small equipment replacement, compare the current programme routes rather than forcing it into REG(E). The REG(E) and EEG route comparison explains that initial choice.

Freeze a credible baseline

Define the baseline period, production level, operating hours, energy sources, meters and data quality. Retain utility bills, meter exports, production records and process assumptions. Explain abnormal shutdowns, expansions or product-mix changes that affect comparability.

Choose a normalisation method where output or weather materially changes consumption. State equations, units, conversion factors and their official source. A single annual total without operating context can overstate the effect of the proposed project.

Model the project case

Describe the physical change and how it reduces energy or emissions. Use supplier specifications, engineering calculations, load profiles and operating assumptions. Identify interactions with production capacity, reliability, maintenance and product quality. Preserve calculation versions and reviewer comments.

Calculate annual abatement in tonnes of carbon dioxide equivalent and show each conversion. Separate direct fuel, purchased electricity and other relevant sources. Do not combine avoided costs with emissions reduction. The model should allow a reviewer to reproduce the result from source data.

Build a qualifying-cost schedule

List equipment, installation, professional services, measurement work and other project costs with supplier, amount, tax treatment and purpose. Separate ordinary replacement, maintenance, financing, internal overhead and unrelated expansion. Link each proposed cost to the physical abatement project.

The official sheet states that support is capped at 50 per cent of qualifying costs and is based on the amount of carbon abatement. A company should not apply the cap as an assumed award rate. Model the investment at full cost and treat any potential support as subject to assessment and approval.

Plan measurement and verification

Specify meters, locations, calibration, sampling frequency, production data and responsibility before implementation. Define how the post-project period will be compared with the baseline and how changes in output or operating conditions will be handled. Budget the required verification work.

The scheme provides for one-time disbursement after project completion and verification of actual emissions reduction. A measurement plan designed after commissioning may be unable to reconstruct missing baseline data. Involve the people responsible for instruments, operations and records at the design stage.

Test operational and financial resilience

Model energy savings, maintenance, downtime, training, replacement parts and useful life separately from the grant calculation. Run downside cases for lower operating hours, weaker efficiency and delayed commissioning. State what remains valuable if support is lower than expected.

Identify safety, environmental, planning and technical approvals that may affect schedule. The current programme is open to the end of financial year 2030, with final approvals by 31 March 2031, but those dates do not guarantee that a late or incomplete project can be assessed in time.

Create the decision and evidence file

Keep the baseline, engineering design, abatement model, cost schedule, quotations, approvals, implementation plan and measurement plan together. Give each calculation a date, owner and source. Record uncertain inputs and the work needed to resolve them.

Have engineering confirm feasibility, finance confirm costs and management confirm the investment case. The EDB incentives directory should be checked for the current route and documents before external submission.

Manage completion as an operating change

During delivery, preserve purchase, installation, commissioning and training evidence. Reconcile changes against the approved scope before committing. After commissioning, collect measurement data using the planned method and retain records supporting the verified result.

Assign ongoing ownership for performance, maintenance and reporting. A successful emissions project should continue to deliver after disbursement. Management should review actual abatement, cost and operational impact against the original model and explain material differences.

Set commissioning acceptance criteria

Define what the contractor must demonstrate at commissioning: installed configuration, safe operation, metering, load performance, controls, operator training and documentation. Link each test to the design assumption used in the abatement model. Record temporary operating conditions that make a test unrepresentative. Acceptance should not depend only on equipment turning on or a supplier stating that expected savings will follow.

Schedule a stabilisation review after the process has run under normal production. Compare measured consumption, output, downtime and quality with the expected range. Investigate drift before the formal verification period is compromised. Keep responsibility for operational tuning separate from independent verification, and record changes to set points or equipment that affect the emissions calculation. This turns measurement into an active management process rather than a final administrative exercise.

Document the counterfactual

Record what would happen without the project: continued operation, planned replacement, production expansion or another technical change. This counterfactual helps reviewers distinguish project-driven abatement from savings that would occur anyway. Support it with asset condition, maintenance and investment records.

Update the counterfactual only when new facts arise and preserve the earlier version. A transparent change record is preferable to adjusting assumptions after results are known. Engineering and finance should approve any material revision.

The REG(E) carbon abatement file is strongest when one transparent chain runs from baseline data to engineering change, cost, verification and ongoing operation. That discipline helps management judge the project before any incentive outcome is known.
