Dynamic Grid Support feature for Vertiv Liebert® EXL S1 UPS
Data Centre Power Innovation of the Year
Entry Description
Dynamic Grid Support feature for Vertiv Liebert® EXL S1 UPS coupled with Vertiv HPL lithium-ion battery cabinet represents the first single-vendor integrated solution on the market combining grid support features, UPS and lithium-ion batteries.

Liebert EXL S1 with Dynamic Grid Support provides static and dynamic frequency regulation by controlling the input power and the batteries charge/discharge based on frequency activation thresholds. It also supports demand management services when the commands to modulate the UPS response are related to demand control flexibility. By enabling UPS grid services with elevated speed of response to frequency variations, Vertiv allows data centre owners to participate in specific demand and response programs (e.g. Fast Frequency Response, Peak Shaving).

A UPS with grid services can provide a rapid response to frequency variations, presenting an opportunity to create value for data center owners. A data center facility is the ideal candidate to implement grid-balancing services since it already has existing assets (i.e., battery energy storage) which usage could be maximized to generate a revenue stream for the owner. Cost Savings opportunities include Reduce transmission (e.g., TNUoS), distribution (e.g., DUoS) and balancing (BSUoS) energy costs with valuable programs (e.g., Triads avoidance targeting TNUos), Energy Arbitrage and Demand Management (Price Based Programs). Revenue potential opportunities include Frequency Response, Reserve, Demand Management (Incentive based programs). As an example, by deploying Liebert EXL S1 with Dynamic Grid Support, a Vertiv customer participating in Ireland’s DS3 Programme - Ireland Delivering a Secure, Sustainable Electricity System - with Enel X could, on average, potentially earn revenues of up to 1 million Euro per year for 10 MW of flexible load. The market for such grid services is strong and growing as both the country and Irish businesses look to decarbonize.

Data centers and other types of critical infrastructure have a key role to play in this shifting energy landscape and are the ideal candidate to implement balancing grid services. This is due to the presence of assets such as battery energy storage, which could be maximized to generate new revenue streams as well as cost saving opportunities, and ultimately alleviate grid infrastructure constraints.

UPS batteries can help in the shift to renewable energy. This is because, when natural energy sources such as solar and wind cannot meet demand, utilities often fall back on carbon-based sources. But the UPS can help maintain a consistent and reliable stream of power. Using the UPS in this way builds assurance amongst businesses that renewables can be used without risking power interruption. This approach could be replicated, enabling data centres to contribute to the efforts in embracing green sources. Using the UPS with Dynamic Grid Support and lithium-ion batteries during times of grid instability can ultimately contribute to decarbonization and transition to green energy, securing the supply of electricity by addressing the unbalance related to renewable power generation, in turn supporting global sustainability. This is critical for our planet as sustainable solutions for digital consumption will be a big part of global efforts to combat climate change and build a sustainable infrastructure fit for the future.
