Energy Management: The Economics of Saving Energy
Judge an energy-saving project like a CFO would — how energy becomes cost, how to tame TNB maximum demand, and how to build a defensible business case with payback, NPV, IRR, life-cycle cost and the abatement curve.

Why Saving Energy Is Really About Money (and Carbon)
Energy management economics starts here: every kilowatt-hour you save is a ringgit kept and a kilogram of carbon avoided. See why efficiency is the first fuel.

Power vs Energy: What You Actually Pay For
Power (kW) is the rate right now; energy (kWh) is power times time. Understand the difference — and why nothing runs at nameplate — before you chase savings.

How to Read a TNB Bill: Energy, Capacity, Network and AFA
Decode Malaysia's new TNB tariff structure 2025: the five charge lines, why AFA is RM0.00/kWh, and how voltage decides whether you pay per kWh or per kW.
- 4
Maximum Demand: Why One Bad Half-Hour Costs So Much
Your maximum demand charge in Malaysia is set by your building's worst 30 minutes of the month, billed in ringgit per kW. Here's how to spot it and clip it.
- 5
Time-of-Use, Green Tariffs and Avoidable Penalties
How Malaysian facility managers cut the electricity rate itself: shift load off-peak, buy green power, and stop power-factor and demand penalties leaking cash.
- 6
Fuel, Heat and Why Thermal Savings Are the Big Money
Boiler efficiency, comparing fuels fairly on RM/GJ, and why a thermal upgrade can be worth roughly ten times a good electrical project in ringgit per year.
- 7
From Kilowatt-Hours to Ringgit and Tonnes of CO₂
A reusable six-step method to turn any energy efficiency measure into annual ringgit saved and tonnes of CO₂ avoided, with two fully worked Malaysian cases.

Simple Payback and ROI: The Quick Screening Tools
Simple payback and ROI are the fastest yardsticks for an energy project. Learn what each one really tells you, the worked maths, and their honest blind spots.
- 9
The Time Value of Money: NPV and IRR Explained Simply
Why a ringgit next year is worth less than one today, and how NPV and IRR turn that idea into go/no-go decisions on energy-efficiency projects. Worked in full.

SIR, BCR and Discounted Payback: Completing the Toolkit
Learn discounted payback, savings-to-investment ratio and benefit-cost ratio, and get a clear decision table for picking the right metric for each audience.
- 11
Building an Energy Project Cash-Flow Model
Build the year-by-year cash-flow model every energy project needs — capex, savings, escalation, replacement, and carbon — with a full 10-year worked capstone.
- 12
Life-Cycle Costing: The Cheapest to Buy Is Often the Costliest to Own
Sticker price is a rounding error over 15 years. Learn life cycle costing for equipment — LCC, NPV, EAC and the CAPEX trap that hides the real lifetime bill.
- 13
The Abatement Cost Curve: Which Measures to Do First
The marginal abatement cost curve (MACC) ranks every energy measure by cost per tonne of CO2 avoided — and shows which carbon cuts are literally free money.
- 14
Sensitivity and Risk: Stress-Testing the Business Case
One NPV number lies; a range tells the truth. Learn one-at-a-time sensitivity, scenario analysis, risk mitigation, and the decision matrix that picks a winner.

Making the Case: A Full Energy Project Appraisal, Start to Finish
A full energy efficiency business case on one boiler upgrade: savings, carbon, LCC, NPV, payback, IRR and sensitivity, ranked in the 5R net-zero hierarchy.
