Utilities cost breakdown: transmission loss stands in for scrap

This guide uses electricity generation as the lead example because it's the most universally understood, but the exact same structure applies to water utilities - just swap "fuel" for water treatment chemicals and "transmission loss" for pipeline water loss.

The costing unit: ONE KWH DELIVERED TO THE CUSTOMER (not one kWh generated at the plant) - because the gap between the two measurement points IS transmission loss, this industry's most distinctive cost.

The generation and distribution sequence

1. Fuel intake - coal, gas, oil (thermal plants) or no fuel at all (hydro, wind, solar).
2. Boiler/turbine operation - burning fuel to raise steam, or converting natural energy directly.
3. Power generation through the generator.
4. High-voltage transmission to regional substations.
5. Low-voltage distribution to end customers.
6. Metering & billing.

Two features unique to this industry

1. Fuel cost - can be ZERO for renewables

Thermal plants (coal, gas, oil) have fuel as their largest cost, fluctuating heavily with market prices. Hydro, wind and solar plants have NO fuel cost at all - the entire cost sits in equipment depreciation (dams, wind turbines, solar panels), which is very large from the initial investment. The two plant types have nearly opposite cost structures despite selling an identical product (electricity).

2. Transmission & distribution loss - a percentage of TOTAL output, not per-unit defects

Electricity is naturally lost along the line to resistance and transformers - unlike discrete-product scrap (individual failed units), this is a PERCENTAGE applied continuously across the ENTIRE generated output. Generated output minus loss equals what's actually delivered to customers - and revenue is only earned on the delivered portion.

Everything else

Equipment (turbines, generators, dams/panels - very large fixed assets, 20-30 year depreciation), labor (plant operations, grid repair), consumables (turbine lubricant, cooling-water treatment chemicals), subcontracted work (specialized turbine maintenance from the original equipment manufacturer), rework (fixing grid faults), freight (nearly absent - electricity travels by wire, no physical transport needed), overhead (operations management, electrical safety).
