Find out how the Smart Grid balances the PG&E electric system

The electricity you are using right now was made less than a second ago. The amount of electricity put into the grid must always balance the amount of electricity that is being used. The Smart Grid gives grid operators tools to help them better understand the electric demand.

Grid operators can quickly react to rapid changes in consumer demand. The operators can adjust the electricity on the grid to match the demand. Grid operators can also manage power sources with variable generation of electricity. The sources include wind or solar energy.

Smart Grid upgrades can benefit Californians with greater energy reliability. The Smart Grid allows PG&E to gain more energy from renewable sources. This innovation is a win for customers, the environment and all of California.
