Manapouri Power Plant

The Manapouri Power Project develops the water resources of Lakes Manapouri and Te Anau for production of electric power by diverting the outflow from Manapouri through a powerhouse to the sea.

The Lakes’ storage, elevation and proximity to the sea make them ideal for hydro-electric development. The ultimate installed capacity of the scheme is 760,000 K.W.

The principal features of the scheme are:

  1. An underground powerhouse at West Arm.
  2. A tailrace tunnel from the powerhouse to the sea at Deep Cove.
  3. Transmission lines from West Arm to Bluff.
  4. Outflow controls of the Lakes (to be constructed).

Water from the Lakes is diverted through the turbines via seven concrete-lined penstocks, passing then through individual draft tubes into a manifold and a 30-foot diameter horseshoe section tailrace tunnel to the sea. The 6 1/4 mile tailrace tunnel runs below sea-level for its entire length to maintain submergence of the turbine runners at all times. A surge chamber and shaft are incorporated with the draft tube manifold to accommodate surge conditions.

The underground machine-hall 600 feet below Lake level is the largest in the Southern Hemisphere, 364 feet by 56 feet. Access to the machine hall for all major equipment is provided by a 1 1/4 mile long modified horseshoe tunnel spiralling down from the surface. Personnel access id by elevator shaft from the control building on the surface.

The machine-hall accommodates seven 142,000 H.P. turbines driving four 100,000 K.W. and three 120.000 K.W. generators. Transformers transform the power generated from 13.8 KV to the transmission voltage of 220 KV. Seven cable shafts connect to the switchyard on the surface above the machine hall.

The transmission line transmits power to the Comalco aluminium smelter near Bluff, 110 miles away, or alternatively into the national power grid.

Access to the site is by launch across Lake Manapouri, where tourists may visit the site and the information centre.
