The Danish cleantech company BattMan Energy, which specializes in implementing battery storage systems (BESS), has chosen Hitachi Energy as the battery energy storage system supplier for its three newest plants in Denmark. Some of the country''s largest BESS facilities, the plants will have a collective effect of 36 megawatts (MW)/72 megawatt-hours (MWh) and can supply around 6,000 Danish households with power for one day. The first two plants are expected to be ready in June 2025.
The agreement is an important milestone for both parties and supports Hitachi Energy''s Purpose of advancing a sustainable energy future for all. BattMan Energy aims to facilitate and execute investments of more than €100 million in batteries to stabilize the electricity grid by the end of 2024 and strengthen Denmark''s position as a global leader in sustainable energy.
He continues, "Together with Hitachi Energy, we have also begun the co-development of an approximately 500-MW/1.5-gigawatt-hour (GWh) BESS in Denmark, which will be a record-breaking project for us."
Claus Madsen, Country Managing Director of Hitachi Energy in Denmark, sees great potential in the battery plants, and says, "Battery energy storage systems are absolutely central to the clean transition, the stabilization of the grid and are a large part of the future energy system. I am delighted to work with innovative and driven customers like BattMan Energy to support the widespread adoption of such advanced technologies at the edge of the grid."
John Finney, Head of Grid Edge Solutions, adds, "Denmark is a clear leader in the energy transition, with a significant amount of generation coming from renewable sources, and storage added at the grid edge closer to where the power is consumed. As the traditional boundaries of the grid change, more energy management and optimization solutions are also needed. BattMan Energy is tapping into a unique and smart opportunity in the market, and we expect to see more of this type of model in Denmark and throughout Europe."
Hitachi Energy acquired eks Energy, a leading supplier of power electronics and energy management solutions for storage and renewables integration, based in Seville, Spain. The complementary advantages of Hitachi Energy''s e-mesh™ BESS system integration capabilities, combined with acquired power conversion solutions (PCS) from eks Energy, are also evident in this BattMan Energy project.
BESS developer and operator Dais Energy will reach ready-to-build (RTB) status on 190MW of a 250MW Denmark project portfolio in the coming months, CEO Daniel Connor has told Energy-Storage.news.
Dais has announced a strategic partnership with developer BattMan Energy to develop, build and operator a battery energy storage system (BESS) portfolio in Denmark, which Connor gave us more details on whilst at last week’s Energy Storage Summit Central and Eastern Europe (CEE) 2024in Warsaw, Poland.
Denmark is aiming for 100% renewable energy by 2050 but has been relatively quiet for large-scale energy storage project news to-date, with 10MWh and 12MWh BESS projects launched this year by Nordic Solar and Better Energy respectively, as well as thermal energy storage pilot projects from Hyme Energy and Kyoto Group.
We asked Connor therefore why Dais had chosen Denmark as a first market of entry and how it would approach commercialising the projects, which will be spread across the country’s two electricity zones – DK1, an EU market, and DK2, a Nordic one.
“Denmark has strong underlying merchant revenues. There is talk of capacity market (CM) and a few other things but we''d rather get in early, you can always take advantage of those later. The important thing is to get in before many others do, to pick up key grid nodes and build projects in the right places,” Connor said.
“Without something like the CM you need to find the right counterparty by talking at the right scale. And then you can either take structures that give revenue security on day-ahead markets which are available, and compare the cost of that to going fully merchant with the financiers who are prepared to back that. The latter is not the norm, I suppose, some of those are strategics.”
“We''ll use third-party traders for commercialising. If we go for the contracted structures that would be announced pretty soon before final investment decision (FID) obviously. If it was merchant we''d wait until we are already well into construction, as that''s where you''ll get the best terms.”
The firm is targeting Germany, Poland and Romania after the Denmark entry (hence his attendance at last week’s event). A lot of the discussions around Poland and CEE are about fine-tuning the business case, with next to none of its expected huge pipeline of grid-scale projects actually under construction yet.
“Everyone knows energy storage will work. You can spend a lot of time arguing about how exactly it will work in every single market but you can still get on with developing while you work that out,” Connor said.
Connor was formerly head of storage EMEA for oil and gas major BP’s clean energy arm Lightsource BP (covered extensively by our sister site Solar Power Portal). Before that, he was head of optimisation and storage sales for the large UK utility Centrica.
Danfoss has entered into a partnership with the Danish Technical University (DTU) to work alongside researchers and other business partners on installing Denmark''s largest grid-connected battery energy storage system (BESS) on the island of Bornholm.
For more than 100 years, fossil-fueled power plants have provided society with electricity, and although Denmark has successfully integrated a high share of renewables into the power grid, there is more work to be done. Today, the need for supply security and power system stability still requires the use of conventional power plants. However, as battery components become more affordable, battery energy storage systems have the potential to take over these services, according to DTU researcher, Dr. Seyedmostafa Hashemi Toghroljerdi.
Currently, we cannot utilize the surplus energy that is produced by renewable sources. The BESS will be able to store this energy, while balancing the grid. To explore the stability of such a smart grid with a high share of renewables combined with battery systems, the BOSS project will develop and demonstrate an advanced battery energy storage system with a total capacity of 1MWh/1MW.
Bornholm has bold ambitions when it comes to creating a green future for their island community. In 2008, the Regional Municipality has decided, that by 2025, the island will be a 100% sustainable and CO2-neutral community, using only renewable energy sources. The BOSS project could be a key enabler in achieving these goals. Bornholm was chosen as test site because it represents a scaled model of the Danish renewable integrated power system and is able to operate both in grid-connected, as well as in island mode.
Danfoss'' role in the project will be that of the converter specialist. For many years, converters have been at the core of the Danfoss Drives business. And just as we are leading experts in power to mechanic conversion, this project will allow Danfoss to further build our position as leading experts in the business of power to power converters.
"At Danfoss, we have a strong interest in learning more about the business value of our converter products in energy storage systems, and to explore how we can support the electricity grid as well as other possible applications of our solutions," explains Jakob Fredsted, Senior Vice President, Technology at Danfoss Drives. He adds, "furthermore, this is an excellent promotion platform for our power conversion business and allows us to show our customers what we are capable of in energy storage systems."
While the first phase of the project consisted mainly of planning and deciding what needs to go into the solution, the next steps will focus on the execution and the development of the BESS. Over the coming months, the team will implement and demonstrate a scaled BESS with the aim to install the utility-scale solution on Bornholm by the end of 2020.
With over 50 years of industry-dedicated experience, Danfoss Drives are experts in creating and sharing solutions that deliver better process precision and superior energy efficiency.
