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 team for all the hard work over the past few months. The team has greatly appreciated your support with our queries and the technical knowledge of your team. We definitely hope we cross paths again in future tenders or work with the TNEI team.”
“Thank you for all the support you have provided throughout the ESR process. We truly appreciate the effort and expertise you have contributed and are very pleased with the quality of the three reports. We look forward to the opportunity to collaborate again should we be successful with the ESR bids.”
“A sincere thank you to the TNEI team for your support in carrying out the network modelling for these sites. Your efforts are greatly appreciated and will undoubtedly strengthen our bid submissions. Thank you again for your hard work and diligence. We look forward to the opportunity to collaborate again in the future.”
