TLT secures same day consents for two major solar developments

UK national law firm TLT has secured Development Consent Orders (DCO) for two Nationally Significant Infrastructure Projects (NSIPs), securing in a single day the combined generation of half a gigawatt of new renewable energy development.

The Dean Moor Solar Farm in West Cumbria - a joint venture between renewable energy developers ib vogt and Firma Energy - is expected to generate approximately 150 MegaWatts (MW) of clean energy, with the potential to power more than 50,000 homes.  

The TLT team played a critical role in shaping and refining the DCO approach, providing extensive legal oversight and strategic input at each stage from project inception through to determination. The process required close collaboration, working alongside global sustainable design and engineering firm Stantec to meet the rigorous legal and procedural requirements of the DCO regime.  

Daniel Kiremidjian (Director of UK & Nordics, ib vogt) said: "We are delighted that development consent has been granted for Dean Moor Solar Farm. This is a significant milestone for ib vogt in the UK — and notably, the first project within our UK portfolio to achieve a Development Consent Order from the Planning Inspectorate. Our success would not have been possible without the dedication, professionalism and knowledge of our legal team at TLT, led by Richard Marsh, who were extremely helpful at every step of the way.”

Richard Marsh, Partner at TLT said: “We were pleased to support such an important infrastructure project and to work closely with our partners at Stantec. It is an exciting time to be involved in nationally significant infrastructure, and we are proud to play a role in delivering projects that are critical to the UK’s future energy and infrastructure needs.”

Richard Marsh, Partner in the firm’s planning team, led the TLT Future Energy team advising on Dean Moor supported throughout the planning process by Lee Tearle Legal Director, Jessica Graham and Rahil Haq, Senior Associates, and a team of Associates.

Consent was also granted by the Secretary of State for Energy Security and Net Zero on the 2^nd July 2026 for the Peartree Hill Solar Farm DCO project. Located in the East Riding of Yorkshire, the Peartree Hill Solar Farm will provide 320MW of clean energy, sufficient to power 167,000 homes.    

The decision marks the culmination of several years' work by the TLT project teams, including a six-month independent examination which closed in January 2026.   

Nadine Janecke, Director of Development UK at RWE said: “We are delighted to have secured the Peartree Hill DCO and would like to thank TLT for their expert DCO guidance, advice and advocacy throughout Examination.”

TLT advised RWE Renewables UK Solar and Storage Ltd on securing consent for Peartree Hill, led by Mustafa Latif-Aramesh, and Tom McNamara, Partner and Legal Director respectively in the firm’s Planning, Environment, Parliamentary and Compulsory Purchase team, supported throughout by Sophie Reese, Managing Associate, Lauren Spencer, Legal Director, Aranya Tharumakunarajah, Senior Associate, and Beth King and Sophie Bloom, Associates.  

Commenting on both transactions, Maria Connolly, Partner and Head of TLT’s Future Energy sector said: “Securing consent for these two major projects on the same day is a fantastic achievement for our clients and a testament to the dedication and expertise of our teams. Together, these projects will deliver clean energy to the equivalent of more than 200,000 homes, making a significant contribution to the UK’s energy transition and energy security ambitions.

“These consents also demonstrate the increasingly important role that innovative legal and technical collaboration plays in delivering nationally significant infrastructure. Across both projects, our teams worked closely with developers, consultants and stakeholders to navigate the complexities of the DCO regime and help bring forward projects that will have a lasting impact on communities and the wider economy.

“We are so proud to be advising on some of the UK’s most impactful energy and infrastructure projects. As investment in renewable energy continues to accelerate, we remain committed to helping clients deliver the large-scale developments that will support the country’s net zero ambitions and future growth.”
