Critical Solar Powered Systems – ( Solar Thermal Magazine)
Saft, has been awarded around 10 million dollar contract by Kentz, a member of the SNC-Lavalin Group and global engineering specialist solutions provider, to supply its Sunica.plus batteries for critical solar powered systems serving Qatar Petroleum’s Dukhan oilfield.
Over the next two years, some 40,000 of the nickel-based Sunica.plus batteries will be deployed at around 775 wells across the oilfield, where they will provide energy storage and backup power for wellhead industrial control systems and corrosion protection systems.
Kentz is currently working on a 190 million dollar contract for Qatar Petroleum to provide a dedicated Supervisory Control and Data Acquisition (SCADA) network infrastructure to monitor the 775 wellheads in the Dukhan Oilfield from designated stations. Kentz’s scope of work also includes the prevention of external corrosion damage to the oilfield’s well casings by installing an impressed current cathodic protection system.
The SCADA network and the corrosion protection systems will be powered by solar photovoltaic (PV) panels working in combination with the Sunica.plus batteries to provide the essential energy storage and backup power to ensure their total continuity of operation. Saft has developed the Sunica.plus battery specifically for this type of stand alone, off-grid solar installation, where its robust nickel-based construction and high cycling capability ensures long life and low maintenance requirements, even when subjected to erratic charging conditions and operating temperatures fluctuating from – 20˚C to + 50˚C.
“Thousands of Saft Sunica.plus batteries are currently deployed at off-grid solar powered sites around the world, where they have demonstrated unrivalled performance and long-life. Kentz’s decision to select them for this very prestigious project for Qatar Petroleum’s Dukhan oilfield is further confirmation thatSunica.plus is the ideal choice for remote, hard to access installations where absolute reliability is essential and routine maintenance is time-consuming and expensive,” says Xavier Delacroix, General Manager of Saft’s Industrial Battery Group Division.
