The European Investment Bank (EIB) has invested €24 million (US$28 million) in cloud-based battery data analytics provider TWAICE.
Germany-headquartered predictive analytics software company TWAICE announced the EIB’s venture financing commitment yesterday (5 February).
The money is provided as a long-term venture debt loan and is backed by the InvestEU programme, formerly the European Fund for Strategic Investments, an initiative to boost the European Union (EU) economy, particularly in the aftermath of the coronavirus pandemic.
The funding will be applied to the company’s activities in both the battery energy storage system (BESS) and electric vehicle (EV) markets, including accelerating product development and expanding its global customer base.

TWAICE and other battery analytics providers collect and analyse millions of data points from batteries, enabling asset owners and operators to gain better visibility into their health, performance, and lifetime. While the analytics primarily assess battery cells, their insights can be leveraged all the way up to the system level.
While BESS manufacturers and system integrators provide their own analytics solutions, specialist analytics providers argue that their platforms enable independent, third-party perspectives and often have longer track records, stemming from participation in the more established EV sector.
TWAICE claimed that its analytics have helped battery storage customers’ systems increase recoverable energy by more than 5% on average and reduce the time taken to analyse performance by 80-90%.
Last week, the CEO of rival analytics company ACCURE, also headquartered in Germany, told ESN Premium that during the recent winter cold weather in Texas, customer assets performed competitively due to the software’s ability to accurately estimate battery state of health (SoH) and state of charge (SoC), among other metrics.
“We’re able to warn owners and operators about potential shortcomings in operation and performance and capacity before they become relevant,” ACCURE’s Kai-Philipp Kairies said.
“Predictive analytics will really tell you exactly what power and energy you can get out of your battery, and if it’s not 100% what you can do to unlock it before [electricity wholesale] prices go up.”
EIB is ‘supporting innovation that enables smarter, more efficient use of clean energy’
Other applications of analytics include increasing the safety of systems, which, along with the obvious advantages, has the business benefit of helping asset owners get improved insurance terms, as ACCURE has done for owner-investor Gore Street.
Another is TWAICE’s recent partnership with battery storage market intelligence firm Modo, in which TWAICE’s analytics are integrated with Modo’s forecasting of market conditions and potential BESS revenues in the ERCOT market.
A statement from TWAICE co-CEO Dr Stephan Rohr emphasised the growing role analytics is playing in the energy storage space, as owners shift from a project-by-project focus to portfolio or fleet management amid rapid industry scaling. The company said its BESS business nearly tripled last year.
TWAICE also works to onboard its battery insights into customer products in the BESS and EV sectors.
“Batteries sit at the heart of Europe’s clean energy future – powering electric mobility, stabilising grids with renewable energy and making our energy systems more resilient,” EIB VP Nicola Beer said.
“By backing TWAICE, we are not only reinforcing Europe’s technological leadership in advanced battery analytics, we are also supporting innovation that enables smarter, more efficient use of clean energy across the economy.”
The EIB invests in energy tech in line with the EU’s Paris Agreement commitments on climate change. It has also made other recent energy storage-related investments in technologies such as Energy Dome’s CO2 Battery and pumped hydro energy storage (PHES) via two projects from Iberdrola, and solar-plus-storage through Mytilineos (now known as Metlen Energy & Metals).
Yesterday, TWAICE published the second edition of its annual BESS Pros Survey, a report compiled through surveys of 117 industry respondents spanning independent power producers (IPPs), asset management and operations and maintenance (O&M), system integrators, EPCs and others.
The survey found that 45% of BESS operators surveyed experience unexpected issues at project sites at least once a month, while the two most critical challenges they face are in system performance and availability (50% of respondents) and revenue optimisation and market participation (44%).
Lennart Hinrichs, TWAICE executive VP and general manager Americas, took part in Energy-Storage.news‘ recent Year in Review 2025 series of interviews, arguing that “analytics providers must move from reactive to proactive operations.”
“Analytics should move away from merely alerting to automated, prescriptive actions that prevent downtime and penalties, translate failure modes into dollar impact (e.g., US$/MWh, avoided fines), and provide audit-ready evidence for lenders, insurers, and warranty claims,” Hinrichs said.
Lennart Hinrichs is taking part in the upcoming free Energy-Storage.news webinar, ‘The Gap Between Data and Insights in Bess Operations,’ sponsored by TWAICE. This session will spotlight key findings from TWAICE’s new 2026 BESS Pros Survey and translate them into practical takeaways for owners, operators, and teams responsible for performance, availability, safety, and revenue.
It takes place Wednesday 11 February 2026 at 2pm EST/11am PST and can be registered for here.
