Critical Loop, an industrial power solutions company, announced the close of a $26 million Series A funding round led by Conifer Infrastructure Partners and Hanover, with participation from Better Ventures, Climate Capital, Adapt Nation Capital, and Cyrus Ventures.
The funding brings the company’s total committed equity and debt financing to $49 million and will support expansion of its modular hardware and software platform designed to accelerate grid interconnection timelines for industrial sites, data centers, and critical infrastructure.
Critical Loop aims to address a key bottleneck in U.S. energy infrastructure, where businesses and utilities often face multi-year delays to connect to or expand grid capacity. Its approach combines battery storage, generation, and its software-defined power controller, Cygnus, into a deployable system capable of delivering power in days or weeks.
The company’s flagship CLB-5100 system is a scalable 1 MW integrated battery platform that can connect to on-site generation, existing grid infrastructure, and distributed energy sources. The system is designed to be relocatable, enabling utilities and operators to address capacity constraints while permanent infrastructure upgrades are underway.
Critical Loop is working with partners including San Diego International Airport and has secured a supply agreement with LG Energy Solution Vertech for domestically manufactured battery systems. The company has also deployed microgrid solutions across industrial and infrastructure use cases, including maintaining operations during outages and enabling faster deployment of EV charging capacity.
The company is currently focused on operations in California and plans to expand into additional regions experiencing similar grid constraints, as demand for power continues to rise due to electrification and digital infrastructure growth.
KEY QUOTES:
“In just a couple of years, we’ve built a software and hardware stack that has the potential to accelerate time to power from years to days, and with this team, we believe we can keep doing things that were previously considered impossible.”
Bala Ramamurthy, Co-Founder and CEO, Critical Loop
“Grid interconnection queues are limiting industrial growth, and the current solutions are mostly slow to deploy and inflexible, which does not meet current need. Critical Loop is working on a timeline that actually matches what customers are dealing with. Critical Loop is delivering a real and immediate solution while also offering customers long-term value beyond solving for today’s need for power, and this team has shown they can deliver on that.”
Nick Stork, Founder and Managing Partner, Conifer Infrastructure Partners
“Moore’s Law-style effects are beginning to deliver in energy and the impact for America is profound. After years of working on advanced technologies, including gallium nitride (GaN) in power conversion and silicon-based lithium-ion batteries, I am excited to be bringing a full-stack industrial and commercial power system to power-hungry companies and grid operators alike. Critical Loop’s CLB-5100 speeds time-to-power and buys down net power cost – adding resilience to the grid while unlocking predictable costs for companies whose growth is at stake. This is quite literally the prerequisite to a new industrial revolution. I am immensely proud of the world-class team delivering the CLB product line with quality and speed.”
Joe Malchow, Founder and General Partner, HNVR Technology Investment Management
“The industrial real estate market in Northern California runs on timelines that cannot afford to sit idle for years. When Critical Loop can get a facility connected in weeks or months, that changes what developers and tenants can commit to.”
Greg Matter, Vice Chairman, Head of Advanced Manufacturing, JLL
