T&D stands for Transmission and distribution, an energy abbreviation.
Network that carries electricity from power plants to consumers: high-voltage transmission lines move bulk power over long distances, and lower-voltage distribution lines deliver it to homes and businesses. T&D costs make up a large share of electricity bills.
Example: The utility's rate increase funds T&D upgrades, including new substations and buried lines.
Usage notes
About 5% of electricity generated in the United States is lost in T&D, mostly as heat in lines and transformers. Aging lines have been linked to wildfires, prompting undergrounding programs in California. Expanding transmission is widely seen as a bottleneck for connecting new renewable projects.
