The EU Data Act came into full force on September 12, 2025, and the energy sector stands at the threshold of a dramatic transformation. This landmark regulation doesn’t just require compliance but it’s a catalyst for a new era of innovation, transparency, and growth across the industry. Energy companies, platform providers, and manufacturers now have unprecedented opportunities to collaborate and deliver smarter, user-centric services.
This shift builds on years of momentum. In recent times, manufacturers and technology partners have taken the lead in developing seamless, secure integrations for connected devices—from heat pumps and EV chargers to batteries and solar inverters. The drive for user choice, data privacy, and true interoperability has gone from being an aspiration to becoming an essential standard shaping the future of energy, and the EU Data Act is the accelerant that will propel these values into the mainstream.
What changes with the EU Data Act? At its core, the EU Data Act puts device users in the driver’s seat. If a device generates data, the person or organization using it owns the right to access that data, control it, and share it securely and by consent with the third parties they trust.
For manufacturers, this means that products sold in the EU must enable easy, secure data access and sharing via standardized, machine-readable formats. Consumers and businesses must be able to authorize energy companies, platforms, or service providers to read or use their device data without being tied to a closed ecosystem.
Manufacturers will need to implement robust consent flows and open up APIs to remain compliant.
For energy companies, this unlocks new ways to engage consumers, optimize assets, and innovate in service delivery. The days of walled gardens and data lock-in are ending.
And for consumers and business end-users, this regulation means genuine freedom: choose the best products, platforms, and energy services powered by their own device data, wherever it lives.
A milestone moment: From closed to open by default The EU Data Act signals a pivotal shift toward open data access across the energy sector, building on years of momentum from forward-thinking manufacturers. Those brands that anticipated this change and invested early in open, secure APIs and user-driven data sharing are now ahead of the curve, ready to thrive in this new regulatory environment.
As the industry embraces this new standard, energy companies have a unique opportunity to move faster and deliver richer, more user-centric services thanks to the new era of interoperability. Kapacity.io is now positioned to help energy companies unlock even greater value by providing streamlined integrations and scalable, compliant solutions that take full advantage of newly opened manufacturer data channels.
But the EU Data Act also levels the playing field. No more proprietary-only data silos. Manufacturers who lag behind risk missing out on integrations, partnerships, and new revenue streams as energy companies seek interoperable solutions. Just like Open Banking transformed finance by unleashing new services and competition, the Data Act is set to unlock a surge of innovation in the energy sector.
Why this benefits everyone Manufacturers can differentiate themselves through transparency and customer-centric design, gaining trust and new partnership opportunities. Energy companies can attract and retain customers by building smarter, more integrated services across brands and device types. Consumers and businesses receive more options to choose the best solution: whether it’s the lowest-cost charging schedule, integrating their battery with an energy app, or gaining new insights into their usage. And crucially, all of this happens with the end-user’s explicit consent and privacy protections at the forefront.
What does a winning solution look like? With the EU Data Act opening a new era of data-driven collaboration, strong solutions stand out by enabling secure, flexible, and user-centric experiences. Here’s what we see as key ingredients for success:
For Manufacturers:
Designing products with seamless, standardized data access, using robust, secure APIs, positions brands to integrate easily with a wide ecosystem of partners. Transparent consent flows and clear privacy controls empower users and build customer trust. Embracing openness and interoperability not only meets regulatory expectations but enhances reputation and fosters innovation partnerships. For Energy Companies and Platforms:
A future-ready roadmap includes services that leverage live device data (with user consent) to deliver value, whether that's dynamic energy optimization, real-time insights, or personalized solutions. Strategic partnerships with manufacturers who are open-data ready will make integration faster, simpler, and more scalable. The ability to offer cross-device, cross-brand solutions will be a differentiator in attracting and retaining modern energy consumers. Collaboration, openness, and a focus on user empowerment will define the market leaders as energy data becomes truly portable and actionable.
