Follow the pipe from the FUEL TANK down into the hole in the ground.

Jump into the freezing water, quickly swim under the ice ledge, surface, and climb out on the far side of the pool. Or, if you'd rather not get wet, back up to the wall near the pipe and take a standing jump with Action to land on the snowy ledge. Then take a running jump to the far ledge.

Turn right and climb the short ladder.

Above is a low tunnel with a series of VALVES. Arrange the fuel valves to match the diagram you saw earlier.

The first gauge already points to red, so leave the first valve alone.

Stand close to the second valve and press Action to turn it so the gauge reads green.

Leave the third valve alone (the gauge already reads red).

Grab the save/power-up crystal.

Then turn the fourth valve so the gauge reads green. When the valves are positioned correctly, a door opens nearby.

NOTE: If you make a mistake, don't worry. You can turn the valves again to reset them.

Wade through the water and climb the ladder into the GENERATOR SHED.

Turn around, hop across the hole in the floor, and go through the open door to the generator. (If you explored here before turning the valves, this door would have been closed.)

Pick up a large medi pack in the back right corner. Then use the switch on the wall between the two machines to turn on the power.
