In this episode of the Connectology® podcast, Connectologists® Kyle Murchie and Pete Aston break down two major updates that could change the game for energy developers.

First up: CMP446. Ofgem has approved a big shift—raising the Transmission Impact Assessment (TIA) threshold in England and Wales from 1MW to 5MW (based on export capacity). That means fewer small and mid-sized projects need to go through the slow and complex TIA process. It’s great news for community energy schemes and demand-heavy sites—but Scotland is left out, with the threshold still set at 200kW.

Then, we dive into the hot topic of queue management. The new rules bring in stricter deadlines—especially the tough two-month window to submit planning after accepting a DNO offer. Miss it, and your project could be kicked out of the queue. Kyle and Pete raise serious concerns about the lack of formal consultation and how this shift could hurt good projects simply due to unrealistic timelines. This episode is packed with practical insights and a clear message: developers need to speak up now.

These changes are coming fast—and feedback from the frontlines could help shape a better, fairer system.

In this episode, Connectologists® Philip Bale and Pete Aston dive deep into Engineering Recommendation EREP130, specifically focusing on its application to embedded battery storage connections under technical limits scenarios. They explore whether it's appropriate for DNOs to enforce EREP130 clauses when offering early connections under Technical Limits, and what this means for customers.

🧠 Key Topics:

• The origin and intent behind EREP130 and how it evolved to handle battery storage.
• How treating batteries as non-firm demand helps avoid costly and unnecessary network reinforcements.
• The controversial application of EREP130 clauses in variations of previously accepted schemes.
• The implications for customers accepting accelerated connections under technical limits — including the risk of losing firm access rights.
• The need for transparency from DNOs and DSOs regarding how these clauses are applied and communicated.
• Real-world examples where the clause was buried in T&Cs, potentially catching developers off guard.
• A call for clearer definitions of "variation" and better industry-wide communication.

💡 Takeaway: If you're a developer or stakeholder in battery storage, this episode is essential listening. Understand what you might be giving up when you accept technical limits offers, and why reading the fine print — and demanding clarity — is more critical than ever.

GC0117 refers to a Grid Code change proposal, initially raised back in June 2018, aimed at improving transparency and consistency of access arrangements for generation and storage connections across Great Britain by creating a common set of requirements. Specifically, the proposal seeks to reduce the existing three thresholds of Small, Medium and Large generators to two, defining Large Power Stations as those with a Registered Capacity of 10MW and above, and Small Power Stations as those below 10MW. Thus, the Medium category would be removed in England and Wales.

Ofgem have opened a consultation on their minded to decision to approve the Original Proposal with the response deadline 11 April 2025. In a departure from the norm, the Connectologists discuss the proposal in the context of 2025 with none of the team supporting implementation. Our Connectologists can almost always debate a topic with the merits of all options discussed, yet in the case of GC0117 this was not straightforward. Listen to Philip Bale, Catherine Cleary, Pete Aston and Kyle Murchie as they draw out some of their key concerns and suggestions.

This episode delves into the complexities of Connections Reform in Great Britain, specifically focusing on the end-to-end review of the grid connection process.

The discussion highlights concerns about the current system, including long queues, potential unfairness for distribution customers, and the need for improved data transparency and communication.

Key takeaways include the importance of:

• Balancing speed and thoroughness: ensuring a robust reform process while maintaining the urgency of addressing the energy transition
• Fairness and transparency in Reform: ensuring decisions on project prioritisation are truly equitable
• Noting transmission vs. distribution challenges: including concerns about underrepresentation for distribution-level projects, and emphasising the urgency of aligning distribution processes with overarching reforms
• Meaningful industry consultation: actively seeking and incorporating feedback from all developers throughout the reform process, especially those who are less involved in industry consultations.
• Improving data availability: enhancing data transparency, quality and accessibility to empower developers and improve decision-making
• Rebalancing obligations: ensuring fair treatment for both developers and network operators
• Ofgem’s end-to-end review: the episode concludes with a call to action for industry stakeholders to actively participate in the end-to-end review consultation by submitting their feedback and concerns to Ofgem by 13 January

This episode provides valuable insights into the challenges and opportunities presented by Connections Reform and offers a crucial platform for industry stakeholders to voice their concerns and help shape the future of grid connections in Great Britain.
