Delivered Power

When we say green power is delivered or is a "delivered product," it means that the green power is fed into the same electric transmission and distribution system that serves the end user. For example, a local wind farm feeds its generated power into the local transmission and distribution system of the local utility, which sells and delivers electricity to a local EPA laboratory. Since the wind power enters the same grid from which the laboratory receives its electricity, the laboratory is said to receive a "delivered" product. While there is no direct electric line between the green power source and the purchaser, green power enters the local grid and replaces electricity that would have been generated from power sources with greater environmental impacts. The purchaser of green power pays more (7.5 cents per kWh) because it costs slightly more to produce the green power.

Electricity enters the power grid through a large number of power generation plants. These plants supply electricity to a large network of transmission and distribution lines, which transmit energy to thousands of end users. Since the electricity from each power plant flows through.

This displacement of an electricity source that has greater environmental impacts with an electricity source that has fewer environmental impacts is the key to green power.

out the entire distribution system, end users have no way of knowing which plant generates their power.
