Inside TotalEnergies’ cloud-based data marketplace: a blueprint

TotalEnergies is working to expand its gross installed renewable electricity generation capacity from 26 GW in 2024 to 100 GW by 2030. The Company is building an integrated power business model, being involved in every step of the process of producing and selling renewable electricity. To achieve this transformation, TotalEnergies needed not only technical solutions but also a new operational model with clear data ownership and governance structures. This meant establishing new roles such as data domain owners and data product owners to facilitate high-quality data sharing across business units while maintaining security and compliance.

At the time, much of TotalEnergies’ integrated power data was siloed. Each business unit had its own data that wasn’t shared with other business units, and data management varied by country. TotalEnergies also foresaw that these siloes would make it difficult for research and development teams to deploy ideas as the Company expanded. “With our exponential growth targets, we needed an environment that could scale with our ambitions,” says Severine Lalande, program manager at TotalEnergies. “This meant creating standardized approaches for onboarding new geographies and assets, integrating weather data for operations, and facilitating both near real-time operational data and historical analytics—all while maintaining security and compliance.”

TotalEnergies worked with AWS Professional Services as well as Accenture to create a data marketplace, called eSpark, built on AWS infrastructure. Using eSpark, teams across TotalEnergies can create and share high-quality data products within a secure governed space. The data marketplace went live in early 2025.

eSpark operates as a comprehensive data marketplace that makes it possible to seamlessly publish, share, discover, and subscribe to data products—packaged, consumable sets of data designed to meet the needs of specific consumers—across TotalEnergies. The solution revolutionizes data sharing across the integrated power value chain. eSpark also delivers strategic data products that facilitate high-value business use cases, and it aligns with business road maps to continue adding value. Now, using eSpark, consumers who previously spent days compiling data for reports can access quality data products in a secure environment within minutes. Additionally, operations teams can now share near real-time operational data from wind and solar facilities to support performance, market activities, and data science efforts.

eSpark uses Amazon Simple Storage Service (Amazon S3), an object storage service. The eSpark architecture was specifically designed to support TotalEnergies’ ambition to increase its electricity production to more than 100 TWh by 2030. It gives TotalEnergies a standard way to integrate varied systems from different geographies, rapidly scale its operations, and remain flexible to continue growing.

eSpark provides a unified governance layer with centralized access control, auditing, and lineage tracking. TotalEnergies implemented robust security controls using AWS Identity and Access Management (AWS IAM) to securely manage identities and access to AWS services and resources. Through the data marketplace, users can perform analytics and create dashboards using third-party integrations such as Databricks. eSpark supports both historical analysis and near real-time operational data, and for data that requires low latency, the solution uses Amazon Kinesis Data Streams to easily stream data at any scale.

Implementing eSpark took teamwork from AWS Professional Services, Accenture, and stakeholders across TotalEnergies. Eight business leaders from four business units drove potential use cases, with other key users involved in testing. TotalEnergies IT architects and cyber experts worked alongside AWS and Accenture to integrate legacy systems and data sources. AWS Professional Services and Accenture contributed the methodology, the product operating model, and the key roles to be included in the program, which helped the team to begin quickly and focus on successive goals as the project went on. “AWS Professional Services and Accenture brought a clear vision and expertise, which helped accelerate the project,” says Lalande. “Their support was important in helping us grow, build momentum, and transition the program to our internal teams.”

The data marketplace reduces times to access data from days to minutes. It also adds value to that data by encouraging the creation of data products that cater to multiple use cases. “By structuring the data in a way that is usable to multiple teams from the beginning, we increase the associated value,” says Lalande.

Just 4 months after going live, eSpark had already onboarded more than 200 users. Creators have deployed data products that serve the entire value chain from renewable operations to trading and analytics teams. The eSpark platform has successfully integrated hundreds of renewable and flexible assets.

Building the eSpark platform on AWS has accelerated TotalEnergies on its journey to use data to effectively reach its renewable energy integration goals. eSpark is creating a data-driven community through structured stakeholder engagement and training programs. “The transformation goes beyond technology—we’ve established new ways of working with clear accountability structures and automated workflows,” says Lalande. “This has facilitated true collaboration across departments, fundamentally changing how teams work with data.”
