Eraring Power Station, New South Wales
- Eraring Power Station, New South Wales
Introduction
Eraring Power Station is one of two coal fired electricity power stations on the shores of Lake Macquarie. Eraring is located on the western shore of the lake, near the township of Dora Creek. It has four steam driven turbine generators, with a total capacity of 2,640 MW of electricity (660MW each).
Development
The first turbine generator was brought online in 1982, with the second and third generators in 1983, and the fourth in 1984. There are plans to upgrade generating capacity of each of the four turbines.
The process of upgrading the control room to a fully digital system was completed in 2005.
Plant Details
Eraring Power Station uses salt water from Lake Macquarie for cooling. This is supplied through a concrete tunnel which passes under Dora Creek and up to the station via open canal. Reclaimed sewerage water which is heavily purified is used to generate steam for the turbines as opposed to the salt water supplies. The salt water helps in the cooling of the superheated steam as well as moderation of the temperature of outlet water to minimise thermal pollution.
The coal for Eraring comes from five mines in the local area, delivered by conveyor, rail and private road. There is significant coal storage capacity on site. Eraring power station employs a system of dust collection where particulate emissions resulting from coal combustion are captured as opposed to being released into the atmosphere. Some of this material is stored in an area nearby while some is taken and used as a component of road base.
Electricity generated at the station is transmitted through high voltage transmission lines. Turbines 1 and 2 are connected to a 330kV transmission line while turbines 3 and 4 are connected to a 500kV transmission line.
