How Does the Electric System Work?
New York’s electric grid consists of high-voltage transmission lines and low-voltage distribution lines that transport electricity from power generation plants to areas that need electricity throughout the state.
- New York electricity generators include both regulated electric utilities and independent power producers with diverse energy sources of generation.
- Natural gas, nuclear power, and hydroelectricity typically provide nine-tenths of net electricity generation, with wind, biomass, coal, and petroleum making up the balance.
- Near generation facilities, power enters a "step-up" substation that increases the voltage.
- High-voltage transmission lines carry the power over long distances to various parts of the state.
- The high-voltage lines enter a "step-down" substation, where they are transformed into a lower-voltage for transmission within the region.
- Many large industrial and commercial customers receive service directly from the lower voltage transmission lines.
- For distribution to smaller residential and commercial areas, the lines enter another step-down substation.
- Distribution lines carry the power through towns and neighborhoods. Small transformers on the poles reduce the electricity to 120-240 volts for each home's use.
