disadvantage of renewables is that they’re only intermittently reliable; when the sun doesn’t shine, or the wind
stops blowing the energy generation capacity of these infrastructures tapers off. In light of these changes there

allow for legacy infrastructures, that would otherwise be a liability for the community, to now be used in a

the way in which such a project would fit within the national electricity market, as well as the limitations and
barriers to implementation it might face before making some brief recommendations on changes that would
benefit other such schemes in the future.
1. Introduction
Metropolitan Bendigo is a regional town of approximately 113,000
people, located 132km North-West of Melbourne (Profile.ID, 2017).
This site has been selected as the case study of this research paper due
to the unique intersection of issues in the energy regulatory environ-
ment (including planning regimes, regulations, and statutes about re-
newable energy generation). This scheme is in the advanced planning
stage,havingalreadycompletedapre-feasibilitystudyitwasfoundthat
not only was the project viable, but that it should continue to be in-
vestigated(DepartmentofEnvironment,Land,WaterandPlanningand
City of Greater Bendigo, 2018).
Also of interest because this technology has the ability to dynami-
cally stabilize energy demand in the grid, whilst simultaneously low-
ering electricity prices in the Bendigo region. As a result of the sus-
tained political uncertainty about the future of the electricity grid in
Australia,andexponentialincreasesinelectricitypricesthroughoutthe
market, the Bendigo local business community has begun to invest in
small-medium scale renewable projects with a view to a more afford-
able,local,andreliablesourceofelectricity(Vallely,2017).Inaddition,
local community activism has driven strong demand for installation of
solar photo-voltaic cells used in rooftop systems (Corr, 2017). Pumped
HydroElectricitySchemes(‘PHES’)operatesasa‘rechargeablebattery’,
which can ‘charge’ from excess energy being produced by such re-
newables, and discharge back into the local energy grid when the re-
newable electricity generators ‘switch off’.
As other PHES projects are now beginning to be researched and
planned throughout Victoria, the case for robust analysis of the issues
surrounding this proposal are warranted. The BSG PHES could become
the blueprint for future PHES within Victoria.
This paper intends to first detail the context in which this idea was

ments will follow, before delving into the administrative competencies

counter (Parliament of Victoria and Economic, Education, Jobs and
Skills Committee, 2017). Concluding remarks then follow.
2. Context
Bendigo has a rich history of gold mining. Beneath the town, nu-
merous mining shafts exist because of gold prospecting and production
from slate belt/turbidite quartz veins that has occurred since the mid
1850′s (Department of Economic Development and Jobs, 2015). This
