Global energy firm E.ON has joined a growing number of international firms that are switching from lead-acid to Saft’s latest generation nickel technology batteries.
The utility has upgraded one of its distribution substations in North West Hungary in a pilot project with the latest ‘plug-and-play’ version of Saft’s Uptimax nickel pocket plate battery.
The batteries will provide backup power to operate switchgear and monitoring and control systems in the case of an outage. Backup power at substations enables utilities to reconfigure the network and clear faults so that technicians can make repairs in safe conditions.
A defining benefit of this new-breed battery is that it can fully charge at a single rather than dual voltage levels, meaning E.ON can upgrade the batteries while retaining its existing charger. Previous models of nickel batteries required a higher charge voltage, which would imply the replacement of existing battery chargers or an upgrade to adjust the charge voltage. The new Uptimax battery requires only a 1.39 V/cell single level charge.
By installing our latest Uptimax nickel batteries, E.ON will benefit from long-term reliability, maintenancefree operation, and rapid return to service – all without replacing or upgrading its battery charger. We believe that this is the first of many successes for the new Uptimax.Roland Knobloch Saft’s Sales Manager for Central Europe.
The nickel technology batteries will provide lifetime savings for E.ON. Unlike lead-acid batteries, they are maintenance free and do not experience sudden death. They can accept fast charging that can achieve 95 percent State of Charge (SOC) in eight hours for a rapid return to service after a power failure.
Saft delivered two battery systems through partner Statron Hungary, the integrator for industrial power supplies. Each system is made up of 170 Uptimax 195 Ah cells.
These batteries are ideally suited for mission-critical applications where reliable backup power is essential, such as oil and gas exploration and production, as well as for utilities and manufacturing plants. Saft’s nickel battery technology offers long-term value over the lifetime of an installation. It provides a long operational life of more than 20 years, high availability and reliability, and a low TCO (Total Cost of Ownership).
