Despite its name, the National Electricity Market doesn’t reach WA. But those charged with guiding the eastern states’ energy transition should look west once in a while.
By boosting the demand for energy from the grid, electric cars could help create an incentive for more renewable energy investment, while smoothing over issues with supply and demand.
The current flurry of energy policy aims to make power cheaper and more reliable. But it will take more than that to meet vital longer-term goals like cutting carbon while keeping future prices low.
Trump has pledged to invest big in infrastructure. An analysis shows the electric grid will need hundreds of billions of dollars over the next decade just to keep things as they are.
South Australia is investing $550 million in a plan to improve the reliability of its electricity. But the side-effect is that the National Electricity Market will now be even harder to run.
The power grid is increasingly computerized. That opens it to attacks and requires new defenses.
Here’s the real problem behind Australia’s electricity woes: the rules that govern decisions about what infrastructure to build, and when, are inflexible and outdated.
Privatisation and competition were supposed to make electricity cheaper. Instead, Australia’s quasi-federal energy system has made it easier to pass the buck when things go wrong.
South Australia’s government was angry about the blackouts enforced by electricity regulators. But with much of the state’s gas power offline, the regulators had little choice.
Managing voltage on the electricity network has always been an issue. But solar panels have the potential to make the situation better, not worse as some have feared.
The Turnbull government is funding energy storage as a crucial missing piece of the electricity grid puzzle. Analysis suggests an affordable, fully renewable grid doesn’t require any heroic assumptions.
Power-hungry houses that rely on air conditioning to make up for their bad design mean that the electricity grid has to cope with summer demand peaks – and everybody pays.
Liberal MP Craig Kelly said businesses and households in Australia are paying twice as much as Americans for their electricity. Is that true?
Batteries aren’t the only type of storage, and all types of storage have their role to play in the future grid.
The potential shutdown of Victoria’s Hazelwood power station could leave a large gap in coal-fired baseload generation. But other coal power stations have plenty of spare capacity to fill the gap.
Australia’s electricity market will be reviewed over the next six months, following South Australia’s state-wide blackout.
In the wake of South Australia’s blackout, politicians have blamed renewables for decreasing the state’s energy security.
Energy isolation would be more expensive and less secure.
Rwanda has adopted a number of plans to improve its electricity output. There are valuable lessons other African countries can learn from it.
