Electricity is the lifeblood of the modern world, but ensuring a stable and efficient grid is becoming increasingly complex.

The challenge is particularly acute in the transition to renewable energy such as wind and solar power.

Unlike traditional fossil fuels, these renewables are inherently variable, meaning their output fluctuates depending on weather conditions.

The solution lies in international cooperation. Imagine a network where excess solar power from a sunny country such as Singapore could be transmitted to a neighbour experiencing a cloudy day. This interconnected grid concept could optimise energy use and maximise the benefits of renewables.

However, achieving this level of international cooperation requires overcoming several hurdles. Regulatory hurdles are a prime example, as exemplified by a recent ABC News report, in which the author of the Northern Territory Government's renewables road map criticised regulation of solar farms amid calls for further investment.

The report highlighted the need for streamlined regulations and clear frameworks to facilitate cross-border energy trade.

The case of idle solar farms in the NT further illustrates the complexities. Four large-scale solar farms near Darwin and Katherine sit idle because of concerns about destabilising the grid with their variable power generation.

The NT Government is exploring solutions. Its recent commitment to building new battery storage projects aims to address the variability issue and pave the way for integrating these solar farms.

Chief Minister Eva Lawler has proposed purchasing the idle farms, potentially giving the Government greater control over energy generation and expediting grid integration.

This case study underscores the critical needs for:

• Clear and efficient regulations which are essential to encourage investment in renewables and facilitate cross-border energy trade.
• Upgrading existing grids and building new transmission lines which are crucial for large-scale renewable energy integration.
• Battery storage which plays a vital role in managing the variability of renewable sources and ensuring grid stability.
• Collaboration between countries which is necessary to optimise energy use and maximise the benefits of renewables globally.

This discussion merely scratches the surface of this complex issue. Continued international dialogue and collaboration are crucial to ensure a stable and sustainable energy future for all.
