High-voltage substations in the United Kingdom - Wikipedia

Some substations in urban areas were installed in enclosed structures but the majority were in the open. The appearance of substations, and their visual impact, was improved using earth mounds and trees. Between 1968 and 1973, 725,000 tall trees, 915,400 smaller trees and 17,600 ground cover plants had been used to screen substations.Get price
