As the energy transition accelerates, so does the demand for smarter, more resilient infrastructure. Battery Energy Storage Systems (BESS) are now a critical part of this transformation—providing the flexibility, reliability, and stability that modern grids need. At Siemens Financial Services (SFS), we recognize that financing is more than capital—it’s a catalyst for innovation and impact.
Across the U.S., SFS is playing a pivotal role in enabling next-generation storage projects. By teaming up with industry leaders and structuring tailored financing solutions, we’re helping bridge the gap between ambition and implementation. Here’s how.
Wolf Tank: Enabling flexibility in South Texas
Grid flexibility is essential in energy-intensive markets like Texas. That’s why SFS, along with CIT (a division of First Citizens Bank), acted as Lead Arrangers for an $84.5 million project financing package for the Wolf Tank energy storage project—a 173 MWh standalone BESS which began commercial operations in 2023.This project supports the South Texas market with much-needed flexible capacity, helping to manage peak load demands and advance grid reliability. Just as importantly, it aligns with SFS’s sustainability principles—helping decarbonize energy supply while delivering tangible operational value.
Bypass: Delivering grid resilience in a rapidly growing market
The Texas grid continues to evolve at a rapid pace—and the demand for scalable storage is growing with it. As Joint Lead Arranger, SFS helped close a $190 million financing package for Project Bypass, a 200 MW / 400 MWh battery storage project near Houston. Bypass is among the first fully contracted energy storage projects in ERCOT (Electric Reliability Council of Texas), making it a blueprint for how innovative financing can drive sustainable infrastructure. Over its lifetime, the project is expected to deliver $20 million in local tax revenue and create hundreds of jobs—demonstrating how impact-driven finance can benefit communities as well as the climate.
Vidal: Supporting California's clean energy goals
California’s commitment to 100% carbon-free electricity by 2045 demands integrated, scalable solutions. For Project Vidal in San Bernardino County, SFS provided structured debt financing to support a hybrid facility combining 160 MW of solar generation with 160 MW / 640 MWh of battery storage. This solar-plus-storage model provides dispatchable clean energy to bolster grid reliability and contribute to California’s long-term decarbonization strategy. Beyond energy delivery, the project also brings economic benefit—generating over $13.5 million in local value and creating up to 260 construction jobs. At SFS, we see long-term customer relationships as a lever for systemic change. Our involvement in these battery storage projects reflects a broader commitment to enabling resilient energy systems, supporting net-zero goals, and unlocking new value across the energy landscape. The transition to a more sustainable, resilient, and economically viable energy future will depend on how well we finance it. We’re proud to help lead that transition. With an experienced and passionate team, we remain committed to enabling the technologies and infrastructure that make net zero not just possible, but inevitable.
