“A lot of unknowns:” Why states may go their own way in “balkanisation” of Australi... - Renew Economy

Renewable Energy Minister Chris Bowen warned that states pursuing separate energy policies risk fragmenting Australia's grid and undermining the national interest. The comment arose amid discussion of states acting independently on renewable energy targets and infrastructure investment, with Bowen flagging "a lot of unknowns" about the consequences of uncoordinated state action.

Where this fits

Fragmented state-by-state energy policy splinters the grid into inefficient silos and prevents the economies of scale that lower whole-system costs. Each state building its own renewable capacity and storage without coordination wastes capital, duplicates transmission infrastructure, and forces each jurisdiction to over-build to meet local demand peaks. This is a cost and reliability problem: the National Electricity Market depends on interconnection and dispatch across state borders to smooth supply variability and balance load. Uncoordinated investment undermines that architecture.

What it means

Balkanisation of energy policy will raise electricity prices and reduce grid stability. States facing pressure to hit renewable targets independently will be forced to invest in local storage and firming capacity that a coordinated national system could provide more cheaply from central generators. The risk compounds if states lock in incompatible transmission standards or pursue conflicting reserve margins. The cure is not faster renewable deployment but clearer national coordination on generation adequacy, interconnection standards, and the role of firm dispatchable power (whether gas, nuclear, or hydro) in meeting reliability obligations. Without it, Australia pays the cost of redundant infrastructure while getting worse resilience.
