This hydroelectric power plant was a power facility located on Szurdok Ridge at Ütközet in the Viery Territory on planet Reach. It provided energy for every settlement in the territory.[2][1]


Circa 2507, a large river that had previously run down from the plateau to the basin, was harnessed by Reach's settlers to produce energy.[1]

At some point before August 11, 2552, the Covenant occupied the entirety of Szurdok Ridge and placed a stealth pylon in the power plant.[3]

On the night of August 11, 2552, Recon Team Bravo discovered a team of Colonial Militia fighting off the Covenant in the upper part of the facility. After assisting them, Recon Team Bravo traveled down to where the Covenant pylon was and planted explosives on it.[3]

On August 12, 2552, Catherine-B320 detonated the explosive and destroyed the pylon.[4]


The power station itself followed the general architectural direction of Reach's pioneer structures; it was composed of multiple rounded sections of structures and built mostly of concrete.[2][3]


This power plant was located in a barren and mountainous region of Reach, on a mountain ridge overlooking a desert basin. A dam was constructed in a narrow canyon not far from the cliff edge. With the dam in place, most of the river's former bed below it had turned into dry land, where the power station had also been constructed. A small fraction of the river ran through the facility, down to the bottom of the basin, where the river had eroded a wide and deep canyon, which now had water only in its very bottom.[2][3]


  • This is the location of the Halo: Reach multiplayer map Powerhouse.
  • This Hydroelectric Plant also forms a latter part of the campaign level Nightfall.
