Chris Pepper (Head of Environment and Consents), Ryan Llewellyn (Consenting Lead), and Ben Parkins (Principal Consultant) recently visited London for a catch up with existing and prospective clients. Pinballing through the ‘Big Smoke’, Chris, Ryan, and Ben spent three days visiting client offices to discuss project progress, explore any market concerns and where future time and energy would be focused, and review whether there were any further ways that TNEI could support in the future. A key theme raised on several occasions was grid reform and all its associated key issues! It was clear that the need to have applications for consent submitted to support grid application is a key consideration for progressing renewable energy projects. A wide breadth of clients were visited, including those requiring TNEI support for due diligence work, noise assessments, battery projects and also electric vehicles, and solar schemes. The team also explored the topic of

We had a vibrant and memorable Onam celebration at TNEI India on 29th August.  Onam, a traditional harvest festival of Kerala, is celebrated in honour of the legendary King Mahabali, who is remembered for his selfless sacrifice and deep love for his people. The festivities at our office were filled with energy and togetherness. Highlights included: Floral Carpet Competition (Pookalam): Our team secured the first prize yet again! Tug of War: Another first prize victory that brought cheers all around. Musical chairs and dance performances kept the spirits high. The celebrations concluded with a sumptuous Sadya served on banana leaves, featuring over 20 authentic dishes. Sarees with jasmine flowers and traditional mundus set the perfect festive mood. It was truly a day of unity, and cultural pride.

The Gate 2 evidence submission window has been extended following an announcement from NESO on Friday (25th July). All projects will now have up until at least the 18th August to submit their Gate 2 evidence to NESO or their relevant DNO. The Story So FarThe DNO evidence submission window has been open since 20th May 2025. This was followed by the NESO submission window which opened on the 8th July, with both windows originally due to close on 29th July. However, on 16th July NESO announced that it would be extending the evidence submission window by a further 5 working days due to a significant number of problems faced by users attempting to submit evidence through the NESO portal. On Friday last week (25th July) NESO announced that the submission window is to be further extended. NESO intend to provide notice of the window closure 10 working days in

In future energy systems, the optimal operation of integrated energy networks – electrical, blended natural gas and hydrogen, pure hydrogen and heat – will require much greater coordination between them, including through storage import and export decisions and power to gas (P2G) plant actions. The feedback loop created by the widespread power-to-gas and gas-to-power will add substantial complexity to system operation.   Many current power-to-gas models adopt certain simplifications to remain manageable. These often involve using broader time or location scales, assuming predictable outcomes, and modelling markets in an idealised way.  But these trade-offs come at a cost. They risk underestimating the complexity of operating integrated energy systems, the assets required, and the investment needed.  For example, models may ignore short-term forecast errors, assume perfect foresight, or drop critical constraints like total energy budgets.  This can lead to inefficient infrastructure planning and operational decisions that compromise energy security or inflate consumer

Since the launch of NESO’s ESR tender in 2022, TNEI has assessed the capability of over 3.9GW of transmission and distribution connected assets to support in restoration service provision. The 19th of May 2025 ITT2 submission deadline for the South West & Midlands ESR tender marked the end of NESO’s first set of tenders for system restoration. TNEI has supported ten clients through all stages of the ESR tender process in the South East, Northern, and South West & Midlands tenders. We used our expertise to provide technical advice to our clients and perform technical studies in assessing the capability of their sites to meet the requirements of the different ESR services – Primary, Top-Up, Anchor (DR) and Top-Up (DR). Client Feedback The following is just some of the positive feedback we received from our clients in supporting them with their technical submissions: “We wanted to thank you and your
