What Smart Wires does
Smart Wires is a privately held grid solutions company founded in 2010 and headquartered in Durham, North Carolina, that develops and sells grid-enhancing technologies for electricity transmission systems. The company's flagship product, SmartValve, is a modular Static Synchronous Series Compensator (SSSC) device that pushes power off overloaded transmission lines or pulls power onto underutilized lines, delivering firm, controllable capacity on existing infrastructure within 12–18 months versus the multi-year timelines typical of new transmission builds. Smart Wires complements SmartValve with SUMO, a network-wide dynamic line rating software that identifies spare capacity above static thermal limits and is compliant with FERC Order 881, and with Analytics, an engineering advisory service staffed by former TSO planners that supports interconnection studies and SmartValve integration.
The business is structured as a platform-plus-modules hardware-and-software portfolio. Smart Wires generates revenue primarily through project-based SmartValve hardware sales, with software licensing for SUMO and professional services for Analytics providing complementary streams. Pricing is enterprise, project-based, and negotiated directly with utility customers under multi-year framework agreements; disclosed contract values include a $29–31M National Grid award and an $18–20M ISA Transelca project over 2022–2024. Go-to-market is enterprise field sales targeting transmission owners and electric utilities in lighthouse markets (UK, Australia, Colombia), with regional leadership across the Americas, Europe, and Germany and channel partners (e.g., Operato, Omexom) supporting deployment and software reselling.
The company is privately held following its delisting from Nasdaq First North Growth Market in March 2023. It has raised more than $200M cumulatively across debt and equity instruments, most recently a $65M growth capital round in January 2025 led by BP Energy Partners with Keystone Group, and has secured named deployments with National Grid, PG&E, EPM, ISA Transelca, GEB, Transgrid, AusNet, and Amprion across more than 15 countries and 40 transmission circuits.
