Tumut 3 Micro Hydro Generators

Cooling Water Micro-hydro Generators installed during 2003-2004 at Snowy Hydro Limited’s largest power station, Tumut 3, are GreenPower accredited.

Green Power is a national accreditation program that sets stringent environmental and reporting standards for renewable energy products offered by electricity suppliers to households and businesses across Australia.

Tumut 3 Power Station consists of six 250 megawatt (MW) hydro-electric generating units, all capable of either generating electricity or operating in synchronous condenser mode.  In addition, three of these generating units have 200 MW underslung pumps used to return water via the pressure pipelines to Talbingo Reservoir.

The Cooling Water Micro-hydro Generators, each with a generating capacity of approximately 120kW each, have been installed to replace pressure-reducing valves on the six generating unit’s cooling systems.

By installing these micro-hydro generators, Snowy Hydro Limited will be saving around 3137 tonnes of carbon dioxide each year that could otherwise be produced by coal burning power stations.  In addition, this installation not only captures previous wasted renewable energy, but also will be substantially reducing the noise that was associated with the previous pressure reducing valves.

Jindabyne Dam Mini Hydro Power Station

As part of the project works undertaken at Jindabyne Dam to allow for increased environmental water flows to the Snowy River, Snowy Hydro Limited constructed a 1.1 megawatt mini hydro power station.

This mini hydro power station utilises some of the environmental water flows to generate clean, renewable electricity.

The mini hydro power station is GreenPower accredited and will save around 5500 tonnes of carbon dioxide each year that could otherwise be produced by coal burning power stations.

Jounama Small Hydro Power Station

Snowy Hydro finished construction, in 2010, of a small hydro-electric power station attached to the existing river diversion conduit at Jounama Dam. The 14.4 megawatt (MW) small hydro enables renewable energy to be economically recovered from the release of waters to Blowering Reservoir and is GreenPower accredited.

If the equivalent amount of electricity was produced by a coal-fired power station, in the order of 53 500 tonnes of carbon dioxide equivalent would be emitted into the atmosphere every year. Construction and operation of the small hydro avoids the release of this amount of carbon dioxide to the atmosphere each year. The small hydro on average generates enough energy to power 6800 homes per annum.

What is GreenPower?

Green Power is a national accreditation program that sets stringent environmental and reporting standards for renewable energy products offered by electricity suppliers to households and businesses across Australia.

The aims of GreenPower are:

  • To facilitate the installation of new renewable energy generators across Australia, beyond mandatory renewable requirements, thereby decreasing greenhouse gas emissions.
  • To encourage growth in consumer demand for renewable energy.
  • To provide consumer choice for, and increase confidence in credible renewable energy products.
  • To promote the renewable energy industry through the rigorous accreditation of generators.
  • To increase consumer awareness of the benefits of renewable energy.
  • To increase the sustainability of Australia’s electricity supply.
