ACCURE Battery Intelligence has received a strategic investment from Copec WIND Ventures, the corporate venture capital arm of Latin American energy company Copec, as the battery analytics company expands into the active operation and optimization of grid-scale battery energy storage systems. Financial terms of the investment were not disclosed.
The transaction follows ACCURE’s $16 million Series B financing completed in 2025 and establishes a strategic partnership focused on Copec’s growing battery storage portfolio in Latin America.
Under the partnership, ACCURE will work with Copec to develop AI-optimized technical asset management capabilities for grid-scale battery energy storage systems, commonly known as BESS.
The agreement represents an expansion of ACCURE’s business model beyond analytics and performance engineering. The company will now use its technology and battery expertise to actively improve the operation and maintenance of assets at scale.
ACCURE’s platform combines artificial intelligence with physics-based battery models to provide owners and operators with visibility into performance across their portfolios, individual systems and battery cells.
The company’s performance engineers use those insights to support operational and commercial decisions intended to increase revenue, reduce operating expenses and mitigate safety and performance risks.
ACCURE currently supports more than 24 gigawatt-hours of battery storage capacity worldwide across more than 100 grid-scale sites.
Battery energy storage systems are becoming an increasingly important part of electricity infrastructure as utilities and energy companies add renewable generation to their grids.
Solar and wind resources can produce substantial amounts of electricity, but their output changes based on weather conditions and time of day. Battery systems can store excess energy when production is high and discharge it when electricity demand increases or renewable output declines.
Grid-scale batteries can also provide frequency regulation, reserve capacity and other services that help maintain power system reliability.
However, battery storage assets differ from conventional power plants because their financial and operational performance can depend on how individual cells age, how accurately their state of charge is measured and how frequently the systems are charged and discharged.
Small inaccuracies can create significant financial consequences across large portfolios.
ACCURE estimates that state-of-charge inaccuracies alone cost battery storage operators more than $1 million per gigawatt-hour annually.
State of charge measures the amount of usable energy remaining in a battery. If the reported level is inaccurate, operators may believe they have more or less capacity available than the system can actually provide.
This can affect trading strategies, dispatch schedules, warranty management and participation in electricity markets.
ACCURE previously addressed a state-of-charge issue at Gore Street Capital’s Dogfish battery storage project in the Electric Reliability Council of Texas market.
By correcting the problem, ACCURE identified an estimated trading revenue increase of more than 5% for the asset.
The company said this example demonstrates how detailed battery analytics can translate into measurable improvements in commercial performance.
ACCURE’s independent data and monitoring capabilities are also used by insurers evaluating battery storage risks.
The company works with insurers including HDI and kWh Analytics, which recognize continuous battery safety monitoring as part of their risk assessment frameworks.
Battery storage projects can face risks involving thermal events, premature degradation, equipment failures, performance shortfalls and warranty disputes.
Continuous monitoring can help owners identify unusual behavior before it develops into a larger operational or safety issue.
ACCURE’s platform evaluates battery performance using both real-world operating data and models based on battery chemistry and physics.
This combined approach is designed to identify issues that may not be visible through conventional dashboards or battery management systems.
The company can examine differences between expected and actual performance, evaluate degradation patterns and identify individual components contributing to portfolio-level underperformance.
Through the Copec partnership, ACCURE will apply these capabilities directly to the operation of battery storage assets rather than limiting its role to providing recommendations.
The companies plan to integrate ACCURE’s predictive analytics and performance engineering into Copec’s asset management practices.
The objective is to improve operational reliability, maximize financial returns and reduce risk across Copec’s battery storage pipeline.
Copec’s investment reflects its continued expansion into the large-scale utility and energy storage markets in Chile and other parts of Latin America.
The region is investing in grid modernization to support growing renewable energy capacity, creating greater demand for storage systems and specialized battery management technology.
Chile has become one of Latin America’s leading markets for renewable energy and grid-scale battery projects.
The country has significant solar generation in its northern regions and expanding wind capacity, but transmission constraints and differences between production and demand create a need for storage.
Battery systems can help reduce renewable energy curtailment by storing electricity that might otherwise be wasted and delivering it when grid conditions are more favorable.
As the number and size of these projects increase, owners need technology that can evaluate battery health, optimize operating strategies and identify performance problems across different equipment suppliers and market environments.
Copec selected ACCURE based on the company’s experience supporting battery projects in established storage markets including the United States, the United Kingdom and Australia.
ACCURE expects to transfer the knowledge gained in those markets to Copec’s Latin American portfolio.
The company was founded by battery researchers from RWTH Aachen University, a European institution known for battery and energy technology research.
Its technical team combines expertise in battery science, artificial intelligence, engineering and energy markets.
ACCURE’s systems are designed to give asset owners an independent view of performance rather than relying exclusively on information supplied by battery manufacturers or equipment vendors.
This independence can be important when owners evaluate whether an asset is meeting contractual guarantees, operating within warranty conditions or generating the financial returns expected when the project was developed.
Independent analytics may also help investors, lenders and insurers assess the quality and risk profile of battery storage portfolios.
The partnership with Copec gives ACCURE an opportunity to demonstrate how its analytics can support a more comprehensive asset management service.
Rather than identifying an issue and leaving implementation to the customer, ACCURE will become more directly involved in the decisions and operating practices used to improve the assets.
The company believes this model reflects a broader shift in the battery storage industry toward specialized, data-driven operations.
As BESS projects mature, owners are increasingly focused on maximizing lifetime value rather than simply bringing additional capacity online.
That requires careful management of battery degradation, maintenance schedules, warranties, market participation and operational risk.
Aggressive trading can increase short-term revenue but may accelerate battery degradation. Conservative operation may protect the equipment but leave potential revenue unrealized.
ACCURE’s platform is designed to help owners balance these considerations by combining technical battery information with operational and commercial objectives.
The strategic investment from Copec WIND Ventures will support ACCURE as it develops these capabilities and expands its presence in Latin America.
The partnership also gives Copec access to battery expertise developed across major international storage markets as it builds a larger portfolio of utility-scale assets.
KEY QUOTES:
“The BESS market is maturing quickly, and asset owners need partners who understand battery performance at a level that goes well beyond monitoring. ACCURE has built that depth supporting more than 24 GWh of assets globally. We partnered with the company because we believe that an analytical and performance engineering foundation is what responsible, returns-focused asset management should be built on.”
Brian Walsh, Global Head of Copec WIND Ventures
“Copec’s investment is a clear signal: the industry is moving toward specialized, data-driven battery operations. Batteries are different from any other generation asset. They require different tools, different expertise and different operating practices. We’re bringing what we’ve learned across more than 100 grid-scale battery storage sites to Copec’s portfolio to minimize risk and extract maximum value from every asset, and this time, we’re not just advising, we’re running them.”
