Powering Data Centers in Santa Clara
Analysis of Powering Data Centers in Santa Clara, based on "Presentation | Powering Data Centers in the South Bay | Sustainable Data Centers Symposium" | Stanford ENERGY.
OPEN SOURCESilicon Valley Power, led by Nico Procos, plays a crucial role in supporting data centers in Santa Clara, focusing on reliability, affordability, and innovation. The utility operates within a compact area, managing a peak demand of 746 megawatts and serving 58 data centers, which are integral to the local economy.
Santa Clara boasts a high energy density of approximately 37 megawatts per square mile, significantly surpassing nearby San Jose. This positions Silicon Valley Power as one of the most energy-dense utilities in California, providing competitive electricity rates that benefit both data centers and local residents.
Data center demand in Santa Clara has increased by 7% from fiscal year 2024, reflecting the industry's expanding operations. Silicon Valley Power is investing around $500 million to enhance its infrastructure, including new transmission lines and upgrades to receiving stations, to support this growing load.
The utility has implemented new strategies to manage rapid load growth, including a substation agreement that enhances control over data center load side breakers. This allows for improved power distribution management during contingencies, addressing the unpredictable behavior of energy-intensive loads.
The Flexible Load Interruption Program, developed in partnership with Emerald AI, aims to increase grid flexibility by enabling data centers to adjust their energy loads in real time. This pilot program is designed to be scalable, allowing for specified ramp-ups and ramp-downs to effectively manage energy demands.

- Data centers are experiencing rapid load growth, requiring increased power and capacity commitments from major customers
- Unpredictable behavior from energy-intensive loads can lead to significant power loss, especially when data centers disconnect during voltage drops
- A new substation agreement enhances control over data center load side breakers, improving power distribution management during contingencies
- The Flexible Load Interruption Program, developed with Emerald AI, aims to increase grid flexibility and accommodate more data centers while managing risks during extreme temperatures
- The electric grids dynamic nature is evolving, indicating that traditional growth management strategies may be inadequate due to the influx of large loads

- The Emerald platform facilitates real-time communication with data centers, enabling them to adjust compute loads or reduce non-critical loads in response to utility signals, thereby enhancing grid reliability
- A pilot program allows the utility to send signals to data centers for managing energy demands during peak usage, with a curtailment provision as a backup if responses are insufficient
- Data centers participate in the program for increased energy access, although they do not receive direct compensation for their flexibility
- Key features of the program include advanced forecasting, historical analysis of past curtailments, event monitoring, and real-time energy dispatch capabilities
- Currently operating at six megawatts, the pilot program is designed to be scalable, allowing for specified ramp-ups and ramp-downs to effectively manage energy loads
The discussion on energy density assumes that current demand patterns will persist, overlooking potential shifts in technology or policy that could alter energy needs. Inference: The historical low growth in energy demand may not be a reliable predictor of future trends, especially with the rise of AI and data centers. Missing variables include the impact of regulatory changes and advancements in energy efficiency, which could significantly affect both demand and supply dynamics.
