DESNZ: navigating UK energy data standardisation
We transformed a complex digital standards environment into a clear roadmap, helping the UK’s Department for Energy Security & Net Zero (DESNZ) understand the role of energy data standards, paving the way for a more interoperable energy future.
Project overview:
- Energy sector faces growing complexity in aligning digital standards across systems, devices, and organisations
- AI-accelerated analysis identifies 50+ high-relevance standards and helps develop a standards hierarchy to serve as a foundation for enabling interoperable data exchange
- Recommendations provide a clear roadmap to accelerate sector-wide coordination
Data interoperability: the key to a resilient energy ecosystem
The energy sector is becoming increasingly complex and undergoing a significant digital transformation towards a more resilient, efficient, and future-proof energy ecosystem. At the heart of this digital evolution is the ability to seamlessly share and integrate data across the sector. Effective data interoperability is therefore a critical enabler of this transition, and achieving it requires establishing and adopting common standards across diverse systems and stakeholders.
The Department for Energy Security & Net Zero (DESNZ) is a ministerial department responsible for UK energy security, protecting billpayers, and reaching net zero. It plays a key role in moving the UK energy sector forward.
In August 2024, DESNZ published the Digital Spine Feasibility Study, investigating how to develop a data sharing infrastructure for the UK energy sector. The study identified priority use cases that would benefit from data interoperability. The next step was to outline recommendations for developing future standards that would enable interoperable data sharing across the energy system infrastructure.
What is data interoperability and why is it crucial for the future of energy?
Data interoperability refers to the ability of different systems, organisations, and technologies to access, exchange, understand, and use data seamlessly, without the need for extensive reformatting or manual intervention.
As technologies like solar panels, heat pumps, electric vehicles, and grid infrastructure become more connected, there’s a growing need for their software systems to ‘speak the same language’.
Data interoperability is what facilitates this. It enables seamless consumer operations and the ability for the energy sector to future-plan. Data standarisation and therefore data standards are at the heart of this and form the foundation for interoperability.
Turning thousands of data types into a coherent strategy
Thanks to our expertise in energy sector digitalisation and successful collaborations with Ofgem and National Grid ESO, DESNZ turned to us for support.
We conducted a comprehensive review of digital standards within the UK energy sector, focusing on how to enable effective data interoperability across an increasingly complex ecosystem. What we found is a patchwork landscape. Different organisations and devices often use their own approaches, creating fragmentation. While some standards exist, such as those for household appliances, many gaps remain, with various players attempting to fill them independently.
To move towards actionable recommendations, we scanned tens of thousands of data types relevant to the energy sector. Next, we used an AI-accelerated process to systematically map these data types to existing standards, identifying which ones best support interoperability. This funnelled approach, helped us shortlist 50 of the most relevant standards.
Our experts then conducted an in-depth review of 8 core families of standards, evaluating their applicability and maturity. Based on this, we developed a high-level hierarchy of standards that can serve as a foundation for interoperable data exchange across the sector. This framework represents an essential first step toward a digitally integrated, future-proof energy system.
Our team emphasised the need for formal information modelling to underpin interoperability. We also identified a need for institutional leadership to facilitate in a central coordinating role to advance this work across the industry.
Charting the path toward interoperable energy data
We helped DESNZ gain a clearer understanding of what standards currently exist, identified critical gaps within those standards, and defined a path forward for a more integrated and future-proof digital energy system.
Our analysis accelerated DESNZ’s progress by simplifying a complex and fragmented standards environment into a more practical, actionable framework.
This was achieved through a number of deliverables:
- 50+ high-relevance standards identified and mapped to energy data types: using an AI-accelerated review process and expert validation, we distilled tens of thousands of potential data types to a focused shortlist of 50 standards most likely to support interoperability. This gave DESNZ a clear, evidence-based starting point for decision-making, cutting through complexity and reducing research overhead by months.
- Comprehensive review of 8 key standard families: our deep-dive analysis of the most critical standard families provided DESNZ with confidence on where to align current and future efforts, avoiding duplication and ensuring compatibility across initiatives.
- Actionable recommendations aligned to sector-wide gaps: we delivered a detailed set of recommendations; each linked to specific actions and responsible stakeholders. This provides DESNZ and the wider energy industry a practical roadmap for progress, offering not just analysis, but direction.
At Zühlke, we see this work as the foundation of a long-term sector capability. Achieving truly interoperable data exchanges won’t happen overnight, but through pragmatic, incremental progress. We’re proud to support this journey and look forward to continuing our work with the UK’s energy leaders as they build a more efficient, resilient, and sustainable energy future.
