Press release<\/p>\n
Wittenberg\/Germany, 12 November 2019. The Norwegian fish farming company Kvar\u00f8y uses a large-scale storage system developed by Tesvolt at its salmon farm located off the island of Sels\u00f8yv\u00e6r in the Norwegian Sea. Mounted on a floating platform, lithium batteries with a total storage capacity of 158 kilowatt hours (kWh) have brought the diesel generators\u2019 operating time down from 24 hours each day to just three. In raising a generation of salmon \u2014 a process which takes about 18 months \u2014 the company saves between 150,000 and 200,000 euros and also reduces its carbon footprint. German commercial storage system manufacturer Tesvolt worked together with Norwegian partner company Kverneland Energi to custom develop, deliver and install the battery system in accordance with the fish farm\u2019s requirements. <\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n Press photos are available here: www.tesvolt.com\/en\/presse\/tesvolt-storage-system-reduces-fish-farm\u2019s-energy-costs.html<\/a><\/p>\n Kvar\u00f8y, a third-generation family-run company, has taken it upon itself to run its fish farm sustainably. A major factor in implementing this policy was reducing the high rates of diesel consumption for operating the fish farm and the feeding systems. Two large diesel generators and one small one are in operation on the anchored concrete platforms. At least one of them must always be running since there is no power connection onboard. At the same time, the electricity demand fluctuates greatly within the course of a day \u2014 at feeding times, the systems require a lot of energy, whereas at other times, only the light on the approximately 20 m by 20 m large motorless ship is shining. Due to long operating periods and poor diesel combustion in the generators, each kilowatt hour of electricity brought with it considerable costs. Additionally, a large portion of the diesel was only used to keep the engine warm while a small portion actually drove the system. On top of that, the fuel has to be transported by boat to the salmon farm, which of course means additional energy and incurred costs.<\/p>\n For this unusual operating location, Tesvolt and Kverneland Energi came up with a special battery system solution. With its 120 kW peak power capacity, the battery system can be monitored and controlled from land over the internet. Power electronics from Siemens control all energy flows on the working platform fully autonomously and deliver electricity to all consuming elements. A diesel generator creates electricity for the batteries at full capacity operation and the electrical energy consumers are supplied by the batteries with the necessary electricity. The generator is not switched on and the batteries are not recharged until the state of charge is low. The battery system allows for a reduction in the fish farm\u2019s total diesel consumption of up to 60 percent.<\/p>\n \u201cTesvolt battery storage systems are the only ones on the market that can be fully charged and discharged twice in one day and still maintain their long service life<\/em>,\u201d Jonas A. Kverneland, Technical Director of Kverneland Energi, reports on his market research. \u201cMany suppliers only enable one storage system charge and discharge cycle per day, which wouldn\u2019t have worked for the salmon farm.\u201d<\/em><\/p>\n Helping to cut costs, the Kvar\u00f8y team now only needs to change the diesel generators\u2019 oil biannually instead of each month. An oil change takes an entire day and costs up to 1,000 euros. That means that the company now saves ten working days and 10,000 euros each year in oil changes alone.<\/p>\n \u201cThe starkly decreased consumption of diesel contributes to climate conservation and keeps water pollution as low as possible,\u201d<\/em> Kverneland says \u2014 a key concern of the Norwegian government. And one of the managing directors of Kvar\u00f8y and Kverneland customer Gjermund Olsen is equally pleased, stating, \u201cWe purchased, installed and forgot about the rechargeable battery. It runs on its own and is totally maintenance-free.\u201d<\/em><\/p>\n His employees, who visit the platform to conduct maintenance work once a week on average, don\u2019t even have to perform additional work thanks to the new energy system. On the contrary: they benefit from improved working conditions. Since the diesel generators are only rarely in operation, noise levels and vibration effects are lowered and the fish farm produces fewer emissions.<\/p>\n For further information, please visit<\/strong><\/p>\n Tesvolt: www.tesvolt.com\/de \u00a0<\/a> About Tesvolt<\/strong><\/p>\n TESVOLT specializes in commercial battery storage systems. The innovative company from Lutherstadt Wittenberg produces storage systems with state-of-the-art prismatic lithium battery cells from Samsung SDI, based on nickel manganese cobalt oxide.
