Transmission and distribution networks

Experienced with different
Transmission System Operators,
Distribution Network Operators
and with generators connecting to
these networks.

TNEI has many years of experience with different Transmission System Operators (TSOs) in different countries including: GB, Ireland, Nigeria, China. We liaise on a daily basis with UK Distribution Network Operators (DNOs) and with generators/developers connecting to these networks.


Some of our recent corporate experience covers the development of transmission master plans for future generation and demand scenarios for Eirgrid and NIE/SONI on projects such as the All Island Grid Study, North-South Interconnector Feasibility, Revision of GB SQSS, North-West Grid Reinforcement for the economically efficient connection of large scale wind generation.

Through the course of this activity we are both maintaining the skill level of our core staff, as well as pushing the boundaries on new analysis methodologies. The projects we are involved in typically provide us contact with the technology supply chain, which keeps us up to date with the current and future technology developments.


TNEI has considerable experience with UK distribution networks both in terms of supporting DNOs on the development of network development plans and technical analysis as well as supporting distribution network end-users such as industrial consumers and generators.

We have significant experience with network modelling and the development of specific applications to assist DNOs in evaluating the technical, investment and pricing implications of major reinforcement projects. A considerable amount of our work is for end users such as windfarm developers seeking distribution network connections. As such. we have experience with the availability and quality of network information, such as the LTDS, as well as the relative efficiency and effectiveness of the connection processes.
