Exploring options to connect multiple customers to renewable energy
National Grid Electricity Transmission signed a contract with a solar developer to connect 37.5 megawatts of solar generation to the 275-kilovolt Hartmoor substation. They appointed us to investigate options on how to proceed with reconfiguring the site to accommodate substantial layout changes and accommodate the connection of multiple customers.
Our services included high voltage electrical design, review of the existing service and utility drawings, and cable entry route options. We also conducted a feasibility assessment for a banked connection and combined layout and elevation drawings showing electrical clearances, maintenance access, and an overall layout detailing the full extent of works needed.
The existing layout of the substation presented a major technical challenge to adapting the site. However, through detailed review during the optioneering process, we determined a layout for Hartmoor that will enable NGET to connect new customers to the substation.
Following completion of the feasibility study, National Grid awarded us the next phase of front end engineering design (FEED) works, which includes more detailed site surveys and intrusive ground investigation works.
