The recent revisions to the National Planning Policy Framework (NPPF) by the UK government have prompted a renewed focus on the potential for renewable energy projects across England. These reforms, which entail significant changes to the thresholds for Nationally Significant Infrastructure Projects (NSIPs), are designed to promote the development of solar and onshore wind projects, aligning with the UK’s long-term energy and climate objectives. However, the path to implementation is not without its challenges, and understanding the nuances of these reforms is crucial for stakeholders in the renewable energy sector.

One of the most notable aspects of the revised NPPF is the reduction of the NSIP threshold for solar and onshore wind projects to 100 MW. This adjustment is intended to streamline the approval process for larger projects, providing a more straightforward pathway for developers seeking to contribute to the UK’s renewable energy capacity. The inclusion of onshore wind within the NSIP framework, following the lifting of a de facto ban that had been in place since 2015, is particularly significant. It opens up new opportunities for harnessing wind energy, which has been underutilised in recent years due to previous regulatory constraints.
The decision to lower the NSIP threshold reflects a broader policy shift towards facilitating the growth of renewable energy infrastructure. However, projects falling below the 100 MW threshold will still be subject to local planning authority (LPA) decision-making. This decentralised approach allows for more localised control over project approvals but also introduces variability, as LPAs have historically faced challenges in granting planning permission for renewable energy projects. Concerns over landscape impact, visual aesthetics, and the utilisation of agricultural land have often led to contentious planning debates, particularly for solar projects.
The revised NPPF aims to address some of these challenges by explicitly stating that the planning system should support renewable and low carbon energy infrastructure. While this is a positive step, the framework stops short of mandating LPAs to designate specific sites for renewable energy in their local plans. This discretionary approach has been met with mixed reactions from industry stakeholders, some of whom argue that a more prescriptive policy could accelerate the deployment of renewable energy technologies.
Gareth Phillips, a renewables expert at Pinsent Masons, has expressed cautious optimism about the reforms. He notes that they provide a more encouraging environment for developers of low carbon infrastructure. However, he also highlights the potential for increased planning appeals, particularly for solar projects that exceed the typical 49 MW threshold that many LPAs have found politically challenging to approve. The success of these appeals will depend on the ability of developers to address local concerns and demonstrate the broader benefits of renewable energy projects. This underscores the necessity for developers to engage proactively with both LPAs and local communities, building support for their projects while addressing environmental and land use concerns.
The government’s commitment to revising the energy National Policy Statements (NPSs) by 2025 is another critical component of the planning reforms. These updates are expected to provide clearer guidance for NSIP applicants and decision-makers, ensuring that the planning system aligns with the UK’s clean power 2030 action plan. By updating the NPSs, the government aims to create a more cohesive policy framework that supports the rapid deployment of renewable energy infrastructure.
Despite these positive developments, the implementation of the planning reforms will require careful navigation by all stakeholders involved. LPAs will need to balance the demands of local constituents with the broader national interest in expanding renewable energy capacity. Moreover, they will need to consider the potential for local opposition, often fuelled by concerns over landscape changes and the impact on agricultural lands.
Ultimately, the planning reforms outlined in the revised NPPF represent a significant opportunity for advancing renewable energy projects in England. By lowering the NSIP threshold for solar and onshore wind projects and reintroducing onshore wind into the NSIP framework, the government is signalling its commitment to accelerating the transition to a low carbon energy system. While challenges remain, particularly at the local planning level, the changes provide a more supportive framework for the growth of renewable energy infrastructure. The successful implementation of these reforms hinges on fostering collaboration between developers, LPAs, and local communities, thus paving the way for a cleaner, more sustainable energy future in the UK.
