Historic Sawyer Stream Hydroelectric Power Scheme
The hot baths and 1920s luxuries of the Southern Alps' most famous hotel were made possible by hydroelectricity.

Tourism in Southern Alps Railways Poster
The Hermitage hotel at Aoraki/Mount Cook has long been a poster image for high-end tourism in the Southern Alps. Behind the luxuries lay hydroelectricity. In 1925 a local hydro scheme was built to power the hot dinners, warm rooms and comforts in the remote mountain hotel. Electricity hugely improved the comfort of hotel guests who had previously depended on open fires and wood fuelled stoves. The hydro station was typical of those once common in remote areas of New Zealand before they were linked to the national electricity grid. The national grid reached Mt Cook in 1961.
It was backbreaking and dangerous work to construct the hydro scheme on the hostile terrain high above the valley floor. The half ton Penstock pipes were hauled up the perilous gradient by hand winched steel cable. The rest of the materials were carried on the backs of men up country only suitable for mountain goats. Accidents were a constant threat with falling rocks. Temperatures were so severe the concrete would not set without boiling the water.
Why visit
Penstock Pipes on Sawyer Stream
The site is of interest if you enjoy exploring industrial archaeology. Much evidence remains spread over the rugged terrain. The easiest site to visit is the powerhouse near the road. The Penstock route up Sawyer Stream is very steep and a visit should only be considered by those with climbing experience.
Conservation
The site is protected in an abandoned state. The old Pelton wheel and generator were relocated to Mt Potts Station and continue to operate.
Getting there
Stop your car about 50m past Unwin Hut, which is 4km before the Hermitage. The power station site is located about 50m east of the road towards the Sebastopol bluffs.
