Coal Plant Efficiency & Decarbonisation Programme
Group ESG Lead
B. Baseline
Current Situation
Two 500MW units operating at current heat rate of 9,800 kJ/kWh, no carbon capture
Baseline Date
Data Quality
Baseline Metrics
Counterfactual
Without intervention, emissions intensity remains flat while carbon price exposure increases
C. Objectives
Intended Change
Reduce heat rate by 4% and Scope 1 intensity by 8% through combustion optimisation and boiler upgrades
Target
Target Date
Affected Stakeholders
Expected Benefits
Reduced fuel cost, reduced emissions, reduced regulatory exposure
D. Options
Alternatives Considered
Full fuel switch to gas (rejected - grid stability risk), carbon capture retrofit (rejected - cost prohibitive at this stage), combustion optimisation (selected)
Do-Nothing Case
Continue current operations with rising carbon cost exposure and no efficiency gain
Reason Selected
Combustion optimisation offers best near-term risk-adjusted return while transition strategy is developed
E. Cross-Pillar Effects Review
Could solving this problem create a different environmental, social or governance problem?
Potential Trade-offs / Unintended Consequences
Improved efficiency could extend asset life, potentially delaying broader decarbonisation transition - to be monitored against group net-zero pathway
This project has completed its Cross-Pillar Effects Review
F. Safeguards
Rights & Stakeholder Impacts
No adverse rights impacts identified
Environmental Impacts
Reduced local air pollutant emissions as co-benefit
Community Impacts
Improved community air quality perception
Mitigation Measures
Continuous emissions monitoring maintained throughout
Grievance Requirements
Community grievance channel remains open
