PVFARM Commercially Launches Energy Storage Design Platform RE STACK

PVFARM launched the commercial version of its platform for utility-scale battery energy storage (BESS) layout exploration, RE STACK. Together with PVFARM, RE STACK forms an expanding suite of tools for utility-scale renewable energy design that enable teams to explore a wide range of layout options before progressing into detailed engineering.

RE STACK integrates into the PVFARM workflow, unlocking BESS layout exploration.

RE STACK allows users to compare and select equipment such as battery containers, PCS or inverter units, transformers, auxiliary equipment, spacing rules, among other vendor-specific requirements.

RE STACK enables engineers to configure utility-scale BESS projects from manufacturer specifications and rapidly explore site layouts, road concepts, and medium-voltage collection topologies before detailed engineering begins.

Key features include

  • Battery recommendation
  • Equipment configuration
  • BESS layout generation
  • Road strategy planning
  • Medium-voltage collection topology planning

Collaboration with over 80 companies during RE STACK and RE PILOT's beta testing directly shaped the platforms' capabilities. Throughout the beta testing process, participants provided feedback on critical design considerations, ranging from equipment selection to power conversion system (PCS) architecture, augmentation planning, fire safety access, and site topology. Beyond ensuring that the platforms solve real-world project challenges, this extensive collaboration also provided the insight needed to shape RE STACK and RE PILOT so they could deliver intuitive, informed decision-making while reflecting the latest technology and market dynamics.

"A lot of software takes forever to make even small changes, but RE STACK stands out from the competition. At Sun2O, we've received a lot of value and saved a lot of time from the platform. RE STACK is a highly useful tool for evaluating our sites, understanding the challenges we face, and being able to leverage PVFARM's existing grading capabilities alongside it," said Vatan Kumar, Vice President, Development Engineering at Sun2O. "Overall, PVFARM's drive to capture all the detailed project inputs and challenge the norm is what impresses me most about RE STACK."

"The future of engineering isn't just designing faster. It's exploring more before you design," said Maksim Markevich, Chief Technology Officer of PVFARM. "With RE STACK and RE PILOT, we're giving engineering teams the ability to evaluate far more possibilities before committing to detailed engineering. The result is better-informed decisions, greater confidence, and a workflow that keeps pace with the growing complexity of utility-scale renewable energy projects."

The International Energy Agency has called energy storage the "fastest-growing power technology today," and the response to RE STACK's beta test program underscores that: 45 organizations enrolled in under a month. Yet, BESS projects often need repeated manual layout concepts before a workable site plan emerges. Stuck between increasing design work and widening applications, developer and EPC teams can rely on RE STACK to generate, evaluate, and compare alternatives earlier by generating BESS layouts automatically, exploring thousands of layout alternatives, testing different road configurations, and MV collection strategies.
