Power is a chain. It breaks at the weakest link.
Gas, generation, transmission and distribution must all improve together — fixing one alone delivers little.
- Built (nameplate)13,625 MW
- Ready to generate4,286 MW
−9,339 MW lost at this step
- Actually sent to grid4,048 MW
−238 MW lost at this step
Then transmission and distribution lose more before power reaches homes. Source: NERC, April 2026.
ATC&C losses: where the DisCo money leaks
EstimateATC&C = Aggregate Technical, Commercial & Collection losses. Every lost or unpaid kWh still has to be bought — so it pushes up the true price and the government's subsidy bill.

This is roughly today's loss level. Move a slider down to see how much subsidy fixing it would save.
Illustrative split of a ~30% ATC&C loss into technical, commercial and collection losses. Not an official NERC breakdown. Shortfall is HYPOTHETICAL: billed kWh from today's utilised MW × (true cost − average tariff paid). Formula: ATC&C = 1 − (1 − technical)(1 − commercial)(1 − collection).

- Gas: supply interruptions and unpaid debts leave plants idle.
- Generation: units break down and wait for parts and maintenance.
- Transmission: lines and substations limit how much power can be moved.
- Distribution: weak local networks and collection losses cap what homes receive.
