Transmission & Distribution Networks

Some of the 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.

As part of our windfarm and conventional generator connection work, TNEI have considerable experience as transmission system end-users and dealing with information provision, availability of transmission system information, connection processes, technical compliance issues and the economic viability of different connection and use of system charges.

The PST team has considerable experience with UK distribution networks both in terms of supporting DNO’s 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 DNO’s in evaluating the technical, investment and pricing implications of major reinforcement projects. Our recent experience in developing the Expansion Planning and Pricing software for Electricity NorthWest, and the development of charging applications for Scottish & Southern, Central Networks, CE Electric and Scottish Power provides excellent insight into the approach of both network owners and system operators to issues surrounding capacity assessment, grid reinforcement and strategic planning, network design and costing, and use of system pricing. Additional work has also been carried out on the calculation of LLFs for Electricity NorthWest and Central Networks.

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.
