🌍🔋 A recent survey of 149 senior data center professionals revealed a staggering 44% are facing utility wait times exceeding four years for new project connections. With such delays becoming the norm, the shift towards on-site energy generation and long-duration energy storage (LDES) is more critical than ever for the industry to scale. Discover how innovations like ESS' Energy Base™ can power data centers with unparalleled flexibility and cost effectiveness compared to other LDES technologies: hubs.li/Q03mlbw90

Building a clean, resilient energy infrastructure will require significant long-duration energy storage (LDES) to meet growing demand from AI data centers and enable intermittent energy sources to provide 24/7 green baseload power. 🌍⚡️ Our field-proven iron flow technology delivers unlimited cycling with zero capacity degradation over a 25-year design life. This means our solutions can be charged and discharged multiple times each day, providing our customers the flexibility to serve multiple use cases with the same asset and optimize the value of excess clean energy.

At ESS, we're redefining long-duration energy storage with our safe, grid-scale iron flow technology—built with earth-abundant, domestically sourced materials and designed to support growing demand from AI data centers and our increasingly electrified society. 🌍 No rare minerals ⚡ Up to 12 hours of energy storage 🔁 25+ year lifespan with no capacity fade Discover the chemistry behind our technology: 👉 hubs.li/Q03lH4D00

A recent study of data center executives highlights the industry’s growing “time to power” challenge, prompting a shift towards alternative solutions to traditional grid power. 44% of respondents said their quoted utility wait times are longer than four years. Consequently, data center operators and businesses are in a unique position to drive this transition to sustainable energy and cannot afford to wait. When paired with solar or other generation sources, ESS’s field-proven iron flow technology can accelerate the deployment of new data center facilities by mitigating interconnection delays and freeing hyperscalers from the constraints of traditional grid power. With onsite long-duration energy storage (LDES) that offers up to 22 hours of backup energy, it allows for unprecedented flexibility in establishing new locations.
