Snowy Mountains Hydro-Electric Authority was corporatised under the Snowy Hydro
Corporatisation Act 1997. The Snowy Water Licence was issued in 2002 under the
Corporatisation Act and is administered by New South Wales (Department of Industry –
Lands & Water).
The NSW Government stated that the sale of the Snowy Mountains Hydro-electric
Scheme will not influence the operation of the Snowy Water Licence or the outcomes

Implementation Deed
The Snowy Water Licence is
subject to mandatory reviews
under the Snowy Hydro
Corporatisation Act 1997. The
first was due after five years
from Corporatisation and
done from the years of 2007
to 2009.
5-year Review

No new dams are being built!
How does pumped hydro work?
Water released during
periods of high demand
when electricity prices
are high.
Water pumped during
periods of low demand
when electricity prices
are low

Required Annual ReleaseThe minimum volume SHL is required to release in one year to either Snowy-Tumut Development or Snowy-MurrayDevelopment. RAR volume contributes to water allocations from the 1 July.
RAR
Dry Inflow Sequence VolumeA measure against the ‘design drought’ of 1936 to 1946.An increase in DISV reduces the RAR and protects the remaining water in Snowy storages.
DISV
Below Target WaterWater in each development of the Snowy Scheme which is intended specifically to meet RAR.
BTW
Above Target WaterWater in each development of the Snowy Scheme which is either available for a particular purpose or can be released at SHL’sdiscretion. Inflows are allocated to ATW when the volume of BTW in storage is high enough to meet future RAR requirements.
ATW
Intended to allow RAR to be reduced if all downstream water needs are met.Relaxation
The Snowy Hydro - commonly used abbreviations
Snowy Hydro 2.0

!
Reasons for building Snowy Hydro 2.0
Providing energy security and reliability to the National Energy Market.
1
Having responsive dispatchable energy generation able to adapt to changing market conditions.
2
Complying with emission reduction targets.3
Also: It provides Snowy Hydro Limited with the ability to expand the offer of financial contracts from future energy generation (‘option contracts’).
The Core Project
Linked to the DISV it was introduced as a Licence amendment in 2011. They are reserves kept as ATW and can be called out ifinflows reach critically low levels. Accounts in each Development are credited with water when a recovery occurs following aperiod when a DISV is triggered.
