Data centres are scaling fast and the energy systems behind them need to keep up. AI, cloud computing, and global connectivity are driving explosive demand, while grid volatility, rising costs, and zero tolerance for downtime push infrastructure to its limits. With global data center power consumption expected to double by 2030, energy storage is no longer optional, it’s essential to stabilise loads, maintain voltage and frequency, and ensure uninterrupted operations.
Wärtsilä’s energy storage solutions deliver the intelligence, flexibility, and resilience needed to keep data infrastructure running 24/7.
Data centres are the digital backbone of the global economy but the energy challenges they face are intensifying.
AI workloads shift faster than traditional power systems can respond, requiring control intelligence that reacts in milliseconds.
Engines, grid-scale batteries, UPSs, and renewables all behave differently and need coordinated, real‑time control to perform as one system.
Data centres must protect people, assets, and operations with robust safety, monitoring, and cyber‑resilient control.
Connection queues and congestion are slowing growth, making resilient on‑site power essential for expansion.
Wärtsilä delivers a unified solution for data centres - combining intelligent software, high-performance hardware, and expert lifecycle services to solve these challenges at scale.
GEMS is the control layer that keeps everything running. It delivers high uptime through layered redundancy, supports both grid-connected and islanded operations, and scales effortlessly across multi-GWh deployments, all while maintaining a hardened cybersecurity posture.
The GridSolve™ product suite is built for speed and resilience. With modular DC and AC block configurations, high power density, and a fully integrated system, it’s designed to support peak shaving, fast commissioning, and smooth the volatile load for critical data centre operations.
From 24/7 remote monitoring to proactive maintenance and end-of-life planning, Wärtsilä’s Lifecycle Services ensure your system performs optimally from day one and beyond.
This visual showcases how Wärtsilä’s integrated solution works together to deliver unmatched control, speed, and resilience for data-centre energy infrastructure. Whether a data centre is grid-tied, fully islanded, or seeking future grid interconnection, our controls and optimisation software, GEMS, manages all energy assets to ensure the most cost and energy efficient, reliable deployment.
Bankable partnerIn a new and innovative space like AI data centres, stability concerns go beyond the grid. The need for financially secure, proven partners is essential. Wärtsilä Energy Storage is a publicly listed company with over 191 years of experience delivering mission-critical energy solutions worldwide.
Safety as a Wärtsilä delivers industry-leading safety with a proven track record and advanced fire safety prevention technologies built into every energy storage solution to protect assets and reduce risk.
Uninterrupted operationsRapid response times and a seamless transition between on- and off-grid operation keep power quality strong even in the case of high voltage jumps or grid outages. Built-in redundancy means your system runs securely and reliably—24/7.
Maintained stabilityGEMS balances the delicate dispatch of renewables, thermal assets, and BESS to maintain consistent power supply while extending asset lifespan, maximising clean energy utilisation, and lowering fuel consumption to keep power costs low.
