How will renewable power affect the reliability of your electricity?

Reliability’ describes how often power outages happen and how quickly the power Wind farm - with logocomes back on. Today, Santa Clara has a high overall system reliability that is aided by our diverse power mix.

What happens when renewable power is added? For utilities and state operators, maintaining reliability will become more complex. Renewable electricity can come from small energy producers in many different locations. For instance, each home with a solar rooftop system produces energy that affects the grid. This can make planning for a steady supply of electricity difficult.

However, even with a more complex process, we will continue providing the same reliable power you expect. Our team is exploring new technologies and processes, like energy storage, that will help us adopt a cleaner power mix and maintain high‑quality service.

The California Independent System Operator (CAISO), the body that manages California’s electric grid, is in charge of planning how renewables will flow on the grid. CAISO is currently testing tools such as demand response, a larger regional power market to balance electricity flow and energy storage to support this increase in renewables.

Utilities will be a key part of this change. Utility employees will need to develop new skills and styles of teamwork. They will also need to use new automation tools to support renewable power and manage the flow of electricity. Operators will watch automated models, check for correctness and take over manually when needed. The process will look like a pilot flying a modern commercial plane, using automation for most of the flight.

Adopting renewables helps us secure a clean future, but the process requires a careful balance in our operations. Our team is dedicated to managing the process while focusing on our customers’ needs. Visit our website for more information on reliability and our power mix.
