Energy storage company Ingrid Capacity is rapidly building battery storage parks. 14 parks will be operational this autumn. To optimize the use of these parks, the company is developing new digital tools and recruiting more data experts.

Ingrid Capacity recently opened a 12 MW battery park (12 MWh) outside Gävle, which is connected to Gävle Energi and approved by the Swedish National Grid. This is one of the company's 14 battery storage parks, totaling about 200 MW, which will be operational in autumn 2024 and will be used mainly for the fast-growing ancillary services market on the Swedish grid. In addition, another 200 MW of energy storage facilities will enter the construction phase this autumn. Since its establishment in 2022, the company has expanded rapidly with external funding and aims to install 8 GW of capacity across Europe by 2030.

Extremely data-driven

But the company’s expansion is not limited to hardware, with an increasing focus on software development – ​​using technologies such as artificial intelligence to develop new digital tools for grid analysis and trading to optimize battery use.

“We are extremely data-driven across the entire value chain,” said Andreas Langholz, Ingrid Capacity’s new head of digital strategy. “This is particularly important in our engagement with grid companies – we are able to show how battery storage can improve local infrastructure through data simulations and show the impact of different options on grid stability.”

Ingrid Capacity has already conducted similar data simulations across the country, analyzing factors such as power demand, grid sites, and demographic development, which provide a basis for the selection of locations for battery storage parks that are about to be put into operation.

Rapid development

According to Andreas Langholz, increasing the level of digitalization is a necessary condition for optimizing the operation of battery parks. Langholz previously led the application of AI in the energy and industrial sectors at McKinsey. He pointed out that energy companies need to pay more attention to the development of digitalization and AI, and said: "In the past year, technologies such as Chat GPT and generative AI have developed rapidly, and they can be widely used in internal processes such as document management, procurement and contract processing."

Ingrid Capacity plans to combine generative AI with machine learning, mathematical optimization and software development, and explore how to combine energy network simulation with visual recognition systems to discover the potential for improvement in power grid infrastructure.

Demand for IT developers

In the past six months, Ingrid Capacity has rapidly expanded its data team, with data experts and software developers accounting for an increasing proportion. By 2030, the company expects to hire 150 to 200 employees, of which the data team will be the largest part. However, finding the right IT talent is not easy.

"IT talent resources are limited, and we are looking for mathematicians, statisticians, data engineers with doctoral degrees, and talents familiar with infrastructure and API management." Langholz said.

He also advised other energy companies to ensure that they have modern infrastructure and high-quality data when using AI to develop data tools, and to start with a few projects and move forward step by step, while encouraging risk-taking.

On August 28, the CEO of South Korean lithium battery company Aricell was arrested in connection with the "Hwaseong Battery Factory Fire" accident, which killed 23 people and injured 9 people.

On the same day, a South Korean court approved an arrest warrant for Park Chun-gwan. Investigators said Aricell's management was suspected of violating workplace safety regulations. The fire was one of the worst factory disasters in South Korea in recent years. Aricell's parent company S-Connect did not respond.

After the fire, Park Chun-gwan issued an apology statement: "We are deeply saddened by the loss of life and express our deepest condolences and apologies to the families of the victims."

He added: "We bear a huge responsibility and will do everything possible to sincerely support the deceased and their families."



At the same time, the court also approved a detention order for Park Chun-gwan's son, who is a senior executive of the company.

Authorities investigating the fire released a report on Friday, saying that the rush to meet supply deadlines and the lack of action to address signs of dangerous quality defects in the batteries produced led to the fire.

Police and labor ministry officials said that hiring temporary workers who had not received proper safety and emergency escape training to make up for the backlog of production led to a large number of casualties.

Aricell is a Korean lithium battery manufacturer established in 2020 by a certain Innovation and a certain Technology. The joint venture's equity is mainly held by Nasdaq-listed S Connect. Aricell focuses on the production of lithium thionyl chloride batteries and is a leading company in the Korean market in this field.
