Ofgem: UK grid connection reform mishandled
Ofgem, the UK's energy regulator, has found that the reform of Great Britain’s grid connections queue was mishandled1, highlighting significant challenges in the nation's energy transition. This critical assessment pointed to missed deadlines, inaccurate connection offers, poor engagement with developers, and substantial digitalisation issues, particularly with the online connections portal. While the grid operator, the National Energy System Operator (NESO), delivered a "good performance" overall in meeting most of its obligations, connections reform was deemed a "critical" objective where improvements are clearly needed.
The mishandling of grid connection reform exemplifies how an outdated system can perpetuate scarcity, hindering the UK's transition to energy abundance. Addressing these bottlenecks requires more than incremental fixes; it demands a fundamental rethinking and rebuilding of energy infrastructure to support a future with "power to play with."
The challenges in grid connections underscore the need for a more efficient and transparent energy system. Fuse Energy is working to build a future where energy is abundant and accessible, making it easier for homes to benefit from modern energy solutions. Click here to switch to Fuse Energy today.

The critical state of UK grid connection reform
Ofgem's assessment of the connections queue
Ofgem's recent assessment revealed that the reform process for Great Britain's grid connections queue fell short of expectations. The regulator's report, examining NESO’s performance during its first full financial year 2025 to 2026, confirmed issues that UK developers had previously raised. These included a failure to implement reforms on time, missed deadlines, and the distribution of inaccurate connection offers. Furthermore, engagement with developers was described as poor, and the rollout of a critical online connections portal faced multiple technical and usability challenges that "could have been mitigated at the time".
The importance of efficient grid connections
Efficient and transparent grid connections are paramount for the UK's energy transition, particularly for integrating new renewable and storage projects. Delays and inefficiencies in this process can significantly impede the deployment of clean energy infrastructure, making it harder to achieve the UK's ambitious decarbonisation targets. The grid connection queue has seen a substantial number of projects, with figures indicating that the capacity in the queue far exceeds what is required to meet clean power goals. Many homeowners are also looking into solar panel installation to generate their own power, further emphasising the need for a robust grid.
Key challenges identified by the regulator
Missed deadlines and inaccurate connection offers
A core finding of Ofgem's assessment was the prevalence of missed deadlines and the issuance of inaccurate connection offers. These operational failures have direct financial implications for developers. Chris Hewett, Chief Executive of Solar Energy UK, highlighted the severity of the issue, stating, "Lots of those offers are way higher than they were expecting, and some of them are wrong, and some are millions of pounds in excess of what they were suggested". Such discrepancies create uncertainty and can derail project financing and planning.
Poor developer engagement and digitalisation issues
The regulator also criticised NESO for poor engagement with developers throughout the reform process. This lack of effective communication, coupled with significant digitalisation issues, particularly concerning the online connections portal, exacerbated the challenges. The portal, described by Ofgem as "critical for delivery," experienced technical and usability problems that could have been mitigated.
What is NESO?
The NESO is a government-owned entity responsible for managing and planning Great Britain's electricity networks. Formed in October 2024 after the UK government acquired the electricity system operator from National Grid plc, NESO's purpose is to facilitate the country's transition to net zero while ensuring energy system reliability and security.
The impact on renewable energy projects
The issues identified by Ofgem directly impact the progress of renewable energy projects, including solar and battery energy storage systems. Delays in securing grid connections can lead to increased costs, extended project timelines, and even the abandonment of viable projects. While reforms aimed to shift from a "first come, "first served" to a "first ready, first served" approach, the execution challenges have created a difficult environment for developers striving to contribute to the UK's clean energy goals.
NESO's performance and response
Overall performance against obligations
Despite the criticisms regarding connections reform, Ofgem noted that NESO delivered a "good performance" overall. The grid operator met or exceeded expectations in seven of its eight performance obligations set by the regulator. This indicates that while the connections reform was a significant area of concern, NESO demonstrated competence in other aspects of its mandate during its first full financial year. NESO was formed in October 2024 when the British government acquired the electricity system operator from National Grid plc.
Acknowledgement of 'difficult reading' on connections reform
Zoe Morrisey, NESO's Director of Legal and Regulation, acknowledged the gravity of Ofgem's findings regarding connections reform. She noted that the section on connections reform "made for difficult reading". Morrisey recognised that the transformation of the grid connections process had not been easy and that the journey had been harder than anticipated.
"We also recognize Ofgem’s feedback that we must find a clearer way of demonstrating value for money, particularly at a time where energy costs are high." — Zoe Morrisey, Director of Legal and Regulation at NESO
Commitment to demonstrating value for money
In response to Ofgem's feedback, NESO has committed to improving its demonstration of value for money. Morrisey stated that NESO is already taking steps to strengthen performance in this area, which is particularly crucial given the current high energy costs. This commitment signals an understanding of the need for greater transparency and efficiency in grid services.
Implications for developers and the energy transition
Navigating an oversubscribed grid connection queue
Developers of renewable energy projects face the ongoing challenge of navigating an oversubscribed grid connection queue. While reforms have aimed to clear projects with queue positions but no real progress, the remaining queue still presents significant hurdles. Projects must now demonstrate readiness and strategic alignment to secure their place, a process complicated by the very issues Ofgem identified. Modern solutions like smart meter installation can help improve data flow and grid management.
The cost and timeline challenges for new projects
The mishandling of grid connection reform translates directly into increased costs and extended timelines for new energy projects. Inaccurate offers and delays force developers to factor in higher financial risks and longer development periods, potentially deterring investment in crucial clean energy infrastructure. This directly impacts the economic viability of projects essential for the UK's energy future.
Accelerating the UK's renewable energy deployment
The success of grid connection reform is intrinsically linked to the UK's ability to accelerate its renewable energy deployment. Without efficient and reliable grid access, the ambitious targets for solar, wind, and battery storage cannot be met. The challenges highlighted by Ofgem underscore the urgent need for robust, well-executed reforms to unlock the full potential of the UK's renewable energy sector.
Towards a rebuilt energy system: a Fuse perspective
The findings from Ofgem's assessment of UK grid connection reform underscore a fundamental truth: the current energy system, designed for a different era, struggles to accommodate the demands of a rapid energy transition. At Fuse, we believe that the persistent bottlenecks in grid connections are not merely operational glitches but symptoms of an underlying system built on a "scarcity story."
Beyond incremental fixes: the need for systemic change
While regulatory oversight and operational improvements from NESO are vital, true progress requires a more profound transformation. Incremental fixes, though necessary, will only ever patch over systemic issues. To truly unlock the UK's clean energy potential, we must move beyond simply managing scarcity and instead focus on rebuilding the energy system from scratch. This means reimagining infrastructure, processes, and regulatory frameworks to support an abundant, decentralised, and resilient energy future.
Unlocking 'power to play with' through grid modernisation
A modernised grid, free from the inefficiencies and inaccuracies highlighted by Ofgem, is central to achieving a future with "power to play with." This vision entails an energy system where connections are swift, transparent, and cost-effective, enabling developers to bring clean energy projects online without undue delay or financial burden. It's about creating an infrastructure that empowers, rather than hinders, the deployment of renewable generation and storage.
The future of UK energy infrastructure
The future of UK energy infrastructure must be one that actively facilitates, rather than constrains, the energy transition. This requires a commitment to not settling for the status quo, but instead rigorously pursuing fundamental change. By addressing the root causes of grid connection challenges and embracing a forward-looking approach, the UK can build an energy system that is not only robust and efficient but also capable of delivering energy abundance for all.
