Grid Assurance

What Grid Assurance does

Grid Assurance LLC is a US-based, privately held limited liability company formed in Ohio in 2016 by American Electric Power, Berkshire Hathaway Energy, and FirstEnergy, later expanded to include Duke Energy, Edison International, Eversource Energy, Great Plains Energy, and National Grid as founding members. The company operates a pooled, subscription-based grid resilience solution that gives transmission-owning utilities expedited access to a dedicated inventory of long-lead-time extra high voltage (EHV) equipment—including large power transformers (230kV and higher in seven rating classes), EHV circuit breakers (three rating tiers), and EHV bushings—stored across multiple secure US warehouses near rail, highway, and water transport corridors. The service is differentiated by pre-approved railroad, state, and local transportation routes, risk-analysis modeling tools that target a 97-98% service level, and 30-year manufacturer warranties, reducing projected delivery time after a catastrophic event from 1+ years for new procurement (or 9-16 weeks via third parties) to 4-6 weeks. The offering is being extended in 2025 to include Generator Step-Up (GSU) transformers and circuit breakers for renewable generation (wind and solar), addressing revenue losses tied to downtime at generation facilities.

Revenues are generated entirely through cost-based, FERC-modeled subscription fees paid by transmission-owning utility affiliates under multi-year contracts, enabling subscribers to recover their expenses and achieving cost economics of 3-5x less than individual utility stockpiling of spares. Subscriber base has grown from the initial 6 utilities and 31 transmission-owning affiliates in May 2018 to 32 transmission-owned affiliates across 23 states. The company is operationally active with a small leadership team (11-50 employees total), maintains strategic warehouse locations whose specific sites are kept confidential for security purposes, and benefits from FERC regulatory clarity established through orders EL15-76 and EL16-20—the only FERC-approved industry-led solution of its kind. Leadership transitioned from founding-era CEO Michael Deggendorf to David E. Rupert in September 2021, and most recently to Stacey Burbure in 2025, drawing leadership from founding owner AEP's transmission regulatory practice.

Core offering

Grid Assurance provides transmission-owning utilities with subscription-based access to a pooled, ready-to-deploy inventory of critical long-lead-time equipment (EHV transformers, EHV circuit breakers and EHV bushings) stored in secure warehouses across the United States. Subscribers benefit from pre-approved transportation routes with rail, state and local authorities, enabling 4–6 week delivery to event sites versus 12+ months for new procurement. The offering is governed by FERC-approved subscription agreements that allow utilities to recover subscription costs through regulated transmission tariffs.

Product overview

Grid Assurance provides an industry-led grid resilience solution built around a shared inventory of critical long lead-time transmission equipment. The core product portfolio includes EHV Transformers (230kV and higher in seven ratings classes), EHV Circuit Breakers (three EHV ratings), EHV Bushings, and GSU Transformers and Circuit Breakers for renewable generation (wind and solar). These equipment products are stored in strategic, secure warehouses geographically distributed across the country and combined with pre-approved delivery logistics to enable rapid grid restoration after catastrophic events including extreme weather, physical attacks, cyberattacks, and natural disasters. The solution addresses high-impact, low-frequency events where equipment would normally take 12-48 months to procure, with Grid Assurance reducing delivery times to 4-6 weeks. Additional product offerings are expected in 2025. Subscribers access pooled assets at costs up to three to five times less than individual stockpiling.
