THE VACA DIXON Power Center PROJECT
The Vaca Dixon Power Center Project is a progressive battery energy storage system (BESS) in Vacaville, California, is designed to support the state’s clean energy transition and the region’s growing demand for electricity.
Project Components
The Vaca Dixon Power Center Project will consist of two components:
Component 1
Vaca Dixon BESS
Component one will consist of a 57-megawatt, 1-hour (57-megawatt hour) battery energy storage solution (BESS) to support California’s decarbonization goals and growing electricity demand. The project will use a collection of one-hour batteries housed in 21 low-profile enclosures, a design that minimizes visual impact while ensuring safe and efficient operations.
Component 2
Arges BESS
Component 2 will include a 100-megawatt, 4-hour BESS (400-megawatt hours) with 50 enclosures of the same low-profile design. The project is ideally sited among similar infrastructure and will feature a creative landscape design including native shrubs and trees, improving the area’s overall beautification.

Strategic Location
Located in Vacaville, California, adjacent to Interstate 80 and near the existing Vaca Dixon Peaker Plant and the PG&E Vaca-Dixon Substation, the project is strategically located to interconnect to the electrical grid and increase grid stability. The Vaca Dixon 57-megawatt hour BESS component is designed to operate in lieu of the Vaca Dixon Peaker Plant which will reduce emissions from gas fueled electricity generation. The overall project will help lower energy costs, improve grid reliability, and strengthen California’s transition to a more resilient, clean energy future.
Project Features
One of the most common questions we receive is: Why here? The answer is usually a combination of factors including:
1. Electricity Demand.
The location is near where more electricity is needed
2. Interconnection.
There is room on the transmission grid to accept and transport more electricity
3. Responsibly Sited.
The project site is well-suited for this infrastructure and any impacts can be mitigated
4. State Policy.
California energy policy has led to greater electricity use and important decarbonization goals
What makes the Vaca Dixon site ideal?

Located where there is a growing need for more electricity

The new infrastructure (transmission and batteries) will be placed in an area near to similar types of infrastructure

The battery system will operate in coordination with the existing natural gas generation; delivering a reliable and cost effective way to meet the demand for electricity
Meeting California's Leadership on Decarbonization
California and Middle River Power are moving fast to cut carbon and meet growing power needs. Our project helps deliver on that goal – adding clean energy while keeping the grid reliable, costs in check, and communities safe.
