Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets.

Energy Secretary Rick Perry wants to know if wind and solar are compromising the reliability of the grid and hurting coal power. The answer lies in his home state of Texas.
Locking down the federal government.

President Trump's new executive order on cybersecurity signals some significant new federal cybersecurity efforts.
Western Australia’s largest private solar array covers the roof of this food distribution centre in Perth’s south.
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.
Just think of it as a battery that can also take you to the shops.

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 long view: energy policy needs to stay firmly focused on the horizon.
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.
Old school: Much of the power plant and transmission network we rely on has been around for decades.
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.
A cyberattack on the electricity grid happened in Ukraine – could it happen here too?
The power grid is increasingly computerized. That opens it to attacks and requires new defenses.
The rules were written at a time when coal and gas were the only major options.

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electricity woes: the rules that govern decisions about what infrastructure to build, and when, are inflexible and outdated.
It’s time to take the political heat out of electricity grids.

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.
High gas prices have left Adelaide’s Pelican Point power station running at less than half its capacity.
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.
Solar panels can be both a headache and an opportunity for network companies.

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.
With the right mix, the grid can go fully renewable for the same cost and reliability as fossil fuels.
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.
You shouldn’t have to crank up the aircon.
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.
Was Liberal backbencher Craig Kelly right about the relative cost of electricity in Australia and the US?

Liberal MP Craig Kelly said businesses and households in Australia are paying twice as much as Americans for their electricity. Is that true?
Batteries may be a good way to store energy in the home.

Batteries aren't the only type of storage, and all types of storage have their role to play in the future grid.
Lights out for Hazelwood, but other power stations can pick up the slack.

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.
Australa’s electricity network is going through a period of major transformation.

Australia's electricity market will be reviewed over the next six months, following South Australia's state-wide blackout.
South Australia’s wind energy is providing secure energy to the state.
