Power System Utilization
Transmission & Distribution System Loss
Loss\% = ((Generation - Delivered) / Generation) \times 100
Variables
| Loss% | System loss percentage | % |
| Generation | Total energy generated/purchased | kWh |
| Delivered | Energy actually billed/delivered | kWh |
Engineering Example
A utility generating 1,000,000 kWh and billing 880,000 kWh: Loss% = (1,000,000−880,000)/1,000,000×100 = 12%.
Practical Site Example
The headline figure utilities like Nepal Electricity Authority track and publish annually as a key efficiency target.
