The Cloudsdale Power Station (name pending) is a location exclusive to My Little Pony: Trinity.
Located in Cloudsdale and one of it's oldest facilities for weather management, It is where electricity is made and clouds are charged with it to become storm clouds, a process that even by pegasi standards is rather dangerous. The facility is still active but with abandoned parts due to storm damage, thus obstacles like broken walkways, forgotten generators, rogue storm clouds and various electrical hazards.
This location fanon to the cartoon, but it is planned to be in the game My Little Pony: Trinity where the Shrine of Loyalty is located at the top of the clouds. However the Power Plant is invaided by pirate Razorbacks with the capability of flight, thus pigs will fly.
