The Challenge of the electric grid

The electricity you are using right now was generated less than a second ago. The amount of electricity put into the grid must always balance with the electricity being consumed. A Smarter Grid provides grid operators with advanced tools that allow enhanced knowledge of what the demand truly is.

With improved management tools, grid operators can quickly react to rapid changes in consumer demand by adjusting the electricity on the grid to match. Grid operators can also manage grid resources to account for variable generation of electricity, say from wind or solar.

These Smart Grid developments will allow Californians to benefit from greater energy reliability while also using more energy from renewable sources — a win for customers, the environment and all of California.
