Clean Green Power for EP
have recently announced the development of a 100 MW wind farm
on the coastline south of Elliston. This major infrastructure
investment in Eyre Peninsula will provide
clean green renewable energy to over 50,000 households in
this State. What's this got to do with water you might ask?
The Tod trunk main is 380 km from the Tod Reservoir (Knotts
Hill) to Thevenard and with its numerous smaller reticulation
mains, it is the aorta of life for the Eyre Peninsula. Within
the Elliston District, and 39 km from the site of the Elliston
Wind Farm is the Polda pump station which pumps Polda Basin
underground water into the Tod main trunk via the Lock Booster
Pump Station. Power for the Polda Pump Station comes from
the electrical mains
substation co-located at the site.
Now, in order for the wind farms to supply electricity to
the grid they are going to build a high voltage transmission
line to the Polda Substation.
This creates the opportunity to construct a major Desalination
plant in proximity of the wind farms, which could utilise
the high voltage energy required to desalinate seawater. The
desalinated seawater could be then pumped (through a supply
main) along the the same corridor as the wind farm transmission
line to Polda substation /pumpstation. It would then be pumped
to the Lock Booster (through the Polda pipeline) which, as
the Eyre regional booster, can supply all connections on the
By utilising existing pumping stations at Polda and Lock
and with construction of a major seawater desalination plant
next to the wind farms there is opportunity to supply all
of Eyre Peninsulas needs both now and into the future.
The other bonus is the wind farms generate electricity through
the day and could pump water at off peak times (its easier
to store water than electricity).
