I havent played the game in awhile but when you first enter the generator room you have to try to turn on the generator, it should need a battery.

Spoiler below!

to locate the fuse you need to destroy some barriers around that big pit in the corner of the room than drag one of the large boxes and drop it into the pit, than climb down to grab it afterwords you need to place the battery in the console.

If you already have the battery placed in the consoles and try to activate the generator the fuse should blow.
exit the generator to find the storage room ( i think there are maps that you can use placed around the tunnels.)

after you manage to reach the storage room there should be a broom.

Spoiler below!

the fuse is hidden on the top of one of the shelves. stack some objects up to reach the top shelf and hit the fuse with the broom

after you replace the old fuse you need to rotate the valves on the consoles

From left to right the valves are going to be called
5,4,3,
----2
----1

Spoiler below!

the order to rotate them i beleive is
Valve 4
Valve 3
Valve 1
Valve 2
Valve 5

after you rotated all the valves move up to the generator and pull the lever and than you are done!
