Tesvolt storage system reduces fish farm’s energy costs

Over 150,000 euros in savings per generation of salmon

Wittenberg/Germany, 12 November 2019. The Norwegian fish farming company Kvarøy uses a large-scale storage system developed by Tesvolt at its salmon farm located off the island of Selsøyvær 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’ operating time down from 24 hours each day to just three. In raising a generation of salmon — a process which takes about 18 months — 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’s requirements.

Storage system cuts diesel use in half

Kvarøy, 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 — 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.

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’s total diesel consumption of up to 60 percent.

“Tesvolt 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,” Jonas A. Kverneland, Technical Director of Kverneland Energi, reports on his market research. “Many suppliers only enable one storage system charge and discharge cycle per day, which wouldn’t have worked for the salmon farm.”

Monthly oil changes reduced to twice a year

Helping to cut costs, the Kvarøy team now only needs to change the diesel generators’ 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.
“The starkly decreased consumption of diesel contributes to climate conservation and keeps water pollution as low as possible,” Kverneland says — a key concern of the Norwegian government. And one of the managing directors of Kvarøy and Kverneland customer Gjermund Olsen is equally pleased, stating, “We purchased, installed and forgot about the rechargeable battery. It runs on its own and is totally maintenance-free.”

Less noise and fewer emissions

His employees, who visit the platform to conduct maintenance work once a week on average, don’t 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.

Europe’s first gigafactory for battery storage systems

Wittenberg/Germany, 6 May 2019 — Europe’s first gigafactory for battery storage systems is being put into operation in Lutherstadt Wittenberg, Germany. Tesvolt, a manufacturer of energy storage systems for industry and commerce, is working to establish new production facilities for lithium storage systems with an annual production capacity of over one gigawatt hour (GWh). Innovations in the production process ensure that the storage systems can be both flexibly and efficiently mass produced. Tesvolt is financing its multimillion-euro investment in the gigafactory without any outside funding, while the EU will lend its support merely to finance around 10 percent of the production line costs. The new production line, warehouse and offices will be fully supplied with solar energy.

The first phase of renovation yielding 12,000 sqm of floor space will be finished in June, and by the final phase, annual production will have reached over one GWh in an area of 20,000 sqm. By then, it is estimated that the number of employees will have risen from today’s 60 to between 100 and 120.

“The world market for stationary energy storage systems has already reached a total capacity of 16 GWh. Europeans are calling for an end to harmful coal-fired power plants and diesel scandals. They want a future free of environmental disasters,” says Daniel Hannemann, who founded Tesvolt five years ago with partner Simon Schandert. “We want the gigafactory to be our contribution to reaching this goal, making clean and affordable energy possible anywhere in the world.”

Innovations in production facilities

The technology for the factory’s new semi-automated production line comes from teamtechnik, a mechanical engineering company known for equipping many reputable automobile manufacturers with production and testing lines. Well-versed in both hardware and software, teamtechnik’s cooperation ensures efficient and safe serial production of battery storage systems. Every battery module will be automatically tested for full functionality, and data from each process step will be recorded for seamless retracing capability.

Carbon-neutral production facilities

The gigafactory is designed for the fully carbon-neutral production of Tesvolt battery storage systems. A photovoltaic installation with a 200 kWp power output will supply the electricity needed for the offices and storage system production. Any excess electrical energy will be stored in the factory’s own Tesvolt batteries, which will have a capacity of 350 kWh. Tesvolt will also employ innovative high-temperature heating pump technology, reliant exclusively on a natural refrigerant, so that even the facility’s heating system will run on solar power.

An agile office concept

The building complex will also house the new office spaces, which are set to be occupied in June. A year ago, Tesvolt introduced an agile organization structure — meaning no more hierarchies. Any and all decisions are made as a team. “Our new office layout reflects this — a generous, open floorplan complemented with many collaboration spaces and quiet zones. We want everyone to feel comfortable here. For us, that is work 2.0,” says co-founder Simon Schandert. “We don’t want to mindlessly process; we want to create innovative solutions. The agile organization makes us more efficient, enabling us to better respond to the rapidly changing battery market.”

As part of the Intersolar Europe exhibition in Munich, Tesvolt will be showcasing its products at the energy storage exhibition ees from 15–17 May 2019.

Tesvolt wins international award for rural electrification

Award ceremony in Ivory Coast

Wittenberg/Germany, Abidjan/Africa, 14 March 2019 – Tesvolt has been presented with an international award for rural electrification. The German manufacturer of power storage systems for agriculture and commerce received the prize in the category Private Sector in Australia, Europe and North America for establishing a sustainable energy supply on an avocado farm in Australia. The award was presented yesterday evening during a ceremony hosted by the Alliance for Rural Electrification (ARE) at the headquarters of the African Development Bank in Abidjan. Last year, the Australian project already won The smarter E AWARD at the Intersolar exhibition.

“This award honours the most passionate and innovative players working to provide people with access to energy. Tesvolt submitted a well-rounded concept which stood out against the rest, particularly with regard to its effectiveness and potential for use in other areas,” said Guilherme Collares Pereira, head judge and ARE Vice President. The international industry organization has approximately 150 members, mostly project developers and technology providers. It has been campaigning for over ten years for low- to middle-income households in rural regions, in particular, to receive access to affordable, safe and clean energy. About 1 billion people worldwide do not have an energy supply, most of them living in Africa, Asia and Latin America.

Technical challenge

“We are particularly proud of this international award for rural electrification because Tesvolt holds fast to the vision of providing affordable, clean electricity to every corner of the world,” says Marcus Kruckow, Vice President of Internationalization at Tesvolt. “And we don’t just provide energy storage, we offer the entire energy solution. With the avocado farm, we were faced with the challenge of combining our lithium storage system with sodium-ion batteries – something never before achieved.”

100% self-sufficient avocado farm

The farm, located in Pemberton in the South West region of Western Australia, produces 90 tonnes of avocados a year on 5 hectares of land. Since they require a very large amount of water and sunlight to develop optimal flavour, the avocados are watered over the hot, dry Australian summer via hydraulic water pumps drawing from underground tanks. The tanks fill up with water over the very rainy winter.

Thanks to the intelligent power storage solution, the farm can now operate with 100 percent solar energy. A photovoltaic installation with a capacity of 53 kilowatt peak (kWp) covers the base load together with a 160 kWh sodium ion-based storage system. The 48 kWh Tesvolt storage system supplies the electricity for the hydraulic water pumps, which require a particularly large amount of electricity upon startup. The sodium-ion batteries are unable to absorb these peak loads as they don’t discharge fast enough. By contrast, the Tesvolt storage system charges and discharges very quickly since it is equipped with Samsung SDI’s high-efficiency prismatic lithium cells. Due to its high performance, this type of battery cell is also used in modern electric cars, for example.


Marketing expert Thomas Franken augments the Tesvolt team

Wittenberg, 8 January 2019 — The beginning of January marks the addition of Thomas Franken, a native of Germany’s Rhineland region, as Tesvolt’s Senior Director of International Marketing. Following stints as a marketing director at SolarEdge, Q CELLS and Hanwha Solar, Franken wishes to boost the international growth of Tesvolt, already a leading manufacturer of storage systems for industry and commerce.

The area with the strongest growth outlook

“Until now, commercial storage systems have represented the smallest area of the battery storage system market — but the one with the strongest outlook for growth. Tesvolt’s special battery management system has already earned it the title of technology leader. But I want to help the company earn the title of market leader,” Thomas Franken explains.

He has been working in the photovoltaics industry for over 30 years and was most recently employed at SolarEdge as Senior Director of Marketing & Communications for Europe, sharing responsibility for the company’s resounding market growth. At Hanwha Q CELLS, he drove the successful repositioning of the Q CELLS and Hanwha Solar brands as the director of global marketing.

Tesvolt opts for agile organization

“Thomas Franken is an extraordinary marketing expert. We’re delighted to welcome him on board,” says Daniel Hannemann, who founded the company four years ago together with Simon Schandert. “At the beginning of this year we got rid of all company hierarchies. This allows us to take decisions more quickly, making us extremely agile and efficient. In keeping with this policy, all the employees in the marketing department decided as one that Thomas should take on our international marketing.”

Tesvolt’s battery management system — a unique selling point

Franken characterizes Tesvolt’s battery management system in particular as a unique selling point: “Tesvolt has huge potential, in great part due to the battery management system developed by the company itself. This is what makes the storage systems especially durable and economical.”

Tesvolt’s battery management system ensures that the battery cells are always optimally charged and discharged. The active cell balancing is not just limited to the cells within a battery module, but also optimizes the different battery modules to fit with each other. The temperature, voltage and state of charge of each individual cell or battery module is monitored, significantly boosting the cells’ lifespan. This gives Tesvolt storage systems a service life of up to 30 years, equivalent to around 8,000 complete charge cycles with a depth of discharge (DoD) of 100 percent.


Tesvolt receives EU funding for high-voltage storage

Brussels / Wittenberg, 4 December 2018

Tesvolt, manufacturer of electricity storage systems for trade and industry, receives 2.15 million euros in EU funding. The European Union sees in Tesvolt's high-voltage storage facility the potential to change the electricity storage market. That is why it supports the Wittenberg-based company as part of its SME support program for series production and the global market launch of lithium high-voltage storage systems. A total of 1,658 companies from all over Europe applied for funding under the SME II program, with 63 companies eventually being awarded the contract.

Halve the cost of commercial electricity storage

"We are looking for the innovation leaders of tomorrow. We regard Tesvolt's high-voltage storage as a disruptive product because it could more than halve the cost of storing electricity, "says Marco Rubinato, EU Program Officer. Instead of previously around 18 cents per stored kilowatt-hour of electricity, the cost could be 7 cents in the future, as soon as Tesvolt produces its high-voltage storage in series. In addition to the construction of semi-automated series production at the Wittenberg site, the funding will also flow into the global marketing of the innovative electricity storage system. The funding is designed for two years.

First European series production for commercial storage

"The EU has recognized that Germany is an important location for battery technology. We are very happy about the financial support and want to build Europe's first serial production for commercial storage, "says Daniel Hannemann, who founded the company four years ago together with Simon Schandert.

Storage technology convinced EU

"Above all, the EU has also convinced our self-developed battery control. It makes our storage systems particularly durable and economical, "explains Simon Schandert. The battery control ensures that the battery cells are always optimally loaded and unloaded. The active cell balancing is not limited to the cells within a battery module, but also optimizes the various battery modules with each other. Temperature, voltage and state of charge of each cell or battery module are monitored, which significantly increases the life of the cells. This means that Tesvolt's electricity storage systems can last up to 30 years. This corresponds to around 8,000 full charge cycles with a total discharge (DoD) of 100 percent.

About Tesvolt
