UPS & STANDBY POWER FEATURE Powering up oil and gas giant’s UPS
Saft and Socomec have pooled resources to supply a high-performance UPS featuring lithium-ion data batteries for Total’s HPC data centre, Pangea II
Flex’ion battery system into Socomec’s DELPHYS Xtend GP UPS. Both components are modular, compact and energy efficient so that the UPS can be scaled to meet new additional power and energy requirements over time. The battery system was developed specifically for data centres and other mission-critical industries. Built with Saft’s Super Lithium Iron
O
il and gas exploration is both costly and challenging. Global giants like
Total view their high-performance computing (HPC) resources and internally developed software tools as critical competitive advantages. In combination with a growing reliance
on data and tightening environmental legislation, it means that operators need ever-higher levels of reliability, energy efficiency and performance. This impacts every area of data centre architecture, including the UPS. To protect Total’s critical information
and calculations, battery maker, Saft, and manufacturer, Socomec, pooled resources to supply a high-performance UPS featuring lithium-ion data batteries for Total’s HPC data centre, Pangea II - one of the world’s largest industrial supercomputers. A unique decision support tool used
for oil and gas exploration and field management, the supercomputer allows to improve the accuracy of subsurface imaging and optimise the development and production of Total’s fields. It also saves time by shortening the duration of studies. Research conducted by the Ponemon
Institute in early 2016 revealed that the average cost of unplanned outages, including direct costs for hardware, services, lost revenue, as well as lost business and reputational damage, is
$9,000 per minute. For the most data-dependent businesses, this figure can skyrocket to $17,000 per minute. Added to the fact that UPS system failure is considered to be the number one cause of unplanned data centre outages, operators are undeniably keen to enhance the reliability of all their UPS components, including the battery system. A high-performance UPS draws on
battery power for periods ranging from one to 15 minutes. This maintains power until the switchgear controls the shift to an alternative utility supply or to a backup diesel genset. In many cases, the UPS also acts as a power conditioner by absorbing or injecting power to overcome the short- term spikes and sags in mains power. The main criteria, therefore, for Total’s
high-performance UPS and battery system were low total cost of ownership (TCO), hot-swappability and full integration with Total’s monitoring systems without additional cost of new battery room infrastructure. The project scope also made provision for enhancing the environmental performance of the data centre through increased energy efficiency (which contributes to a data centre’s overall power utilisation effectiveness), and the ability to re-inject power from the UPS into the grid or to support other loads. To meet these requirements, Saft and Socomec teamed up to integrate a Saft
Phosphate (SLFP) technology, the lithium-ion battery system is sized to deliver 550kW for up to seven minutes after an operational life of 15 years, within the voltage window required by the UPS. The partners integrated two identical UPS with Flex’ion Li-ion batteries for redundancy. Supplementary to the battery system,
Socomec’s technology is hot-swappable to enable extension or maintenance without interrupting data centre operations. The UPS system can be extended by up to 2,400kW with additional 200kW modules. The lithium-ion battery technology
offers the benefits of low maintenance, safety, and high-power density, as well as a long life at elevated temperatures, which reduces the need for cooling and ventilation. In addition, Li-ion can be integrated
with electronic monitoring systems, enabling condition-based maintenance. Compared with lead-acid batteries that
are used widely in data centres, Li-ion brings higher power and energy density, meaning that it can deliver more power with less footprint and lower weight for more time over a longer life. With no risk of sudden death and low maintenance requirements, Flex’ion battery systems boasts high availability. This minimises the likelihood of an unplanned outage. In addition, they are amenable to fast charging, increasing system availability after an outage or discharge.
