Energy prices soar after volatile wind saw heavier gas, hydro and battery use, Australian regulator says

Posted on by

But wholesale prices are down by 25% compared with the June quarter in New South Wales, down 9% in Victoria and down 12% in Tasmania

Wholesale power prices across much of eastern Australia were sharply higher in the September quarter from a year earlier because of increased reliance on gas, hydro and batteries, the Australian Energy Regulator said in its quarterly report.

Average prices ranged from $114/megawatt-hour in Queensland to $201/MWh in South Australia. The biggest year-on-year increases were in Tasmania, with prices up 290%, Victoria’s increasing 114% and SA’s 76% higher.

US admits dams in Pacific north-west have devastated Native Americans

US says dams killed off salmon, inundated villages and burial grounds, and spirited wealth away from tribes

The US government, in a report published on Tuesday, acknowledged for the first time the harms that federal dams have inflicted on Native American tribes in the US Pacific north-west.

The report by the interior department details the “historic, ongoing and cumulative impacts of federal Columbia River dams on Columbia River Basin Tribes”, including how dams on the Columbia and Snake Rivers have devastated salmon runs, inundated villages and burial grounds, and deprived tribal members of the ability to exercise traditional ways of life.

Concern has been raised about the water levels of Loch Ness and the River Ness amid the protracted dry spell affecting Scotland and the rest of the UK.

Brian Shaw, the director of Ness District Salmon Fishery Board, said there had been a dramatic shrinkage in the size of the River Ness. He told the BBC: “These conditions are not normally good for angling.

Ukrainian authorities call for people living downstream of Nova Kakhovka dam to evacuate in face of potentially deadly flooding

Thousands of people have been forced to flee their homes and an ecological disaster has been unleashed on southern Ukraine by the collapse of a major hydroelectric dam on the Dnipro River, which Kyiv said was blown up by Russia in a desperate attempt to ward off a Ukrainian counteroffensive.

Ukraine’s president, Volodymyr Zelenskiy, declared the destruction of the Nova Kakhovka dam an “environmental bomb of mass destruction” and said only liberating the entire country could guarantee against new “terrorist” acts.

Spy boss says terrorism threat lower – as it happened

This blog is now closed.

The conversation moves on to Stan Grant and whether Richard Marles agrees with some of the comments ABC news boss Justin Stevens has made about the criticism Grant experienced by organisations like News Corp and its “relentless campaign”.

Marles is asked whether he has read some of the comments under articles about ABC staff which appear in newspapers like the Australian.

Should those newspapers be dealing with the consequences and the commentary? I’ve read some of them I’ve read some of them about myself, too. They’re revolting.

Look, I mean, they are revolting. It’s it’s an area in an age of social media where – where there are comments that are posted, well – anyone who engages in social media, I think we all need to do much better.

And the answer the question about why I haven’t read all them is precisely because of the impact which one has when you do read them all.

Australia at risk of electricity supply shortages as renewable projects lag behind coal plant closures

Posted on by

Successive La Niñas have eased demand but with many renewable and storage projects now delayed, the energy market operator has revised its projections

Australia’s main electricity grid will probably avoid major supply shortages next summer, but risks escalate in later years as ageing coal plants exit potentially faster than new renewables and storage projects come on line.

The projections are contained in the Australian Energy Market Operator’s (Aemo) updated Electricity Statement of Opportunities (Esoo) report, released on Tuesday.

Water levels in southern Norway so low domestic consumers may be prioritised over international customers

British consumers could face even higher bills and potential energy shortages this winter after Norway threatened to ration electricity exports.

The UK receives hydroelectric power from Norway through a subsea interconnector cable running beneath the North Sea.

As the temperature cools, the heat is on Chris Bowen

Gas shortages, reported delays to major projects and coal-fired power woes are among the gifts handed to the new energy minister

It’s a shame Chris Bowen can’t harness some of the heat from his baptism of fire as new energy minister because it could come in handy this winter.

Even before he’d been sworn in, Victoria nearly ran out of gas. This week, there were more coal-fired power woes – with AGL Energy down to six of its 11 units operating – and a new winter demand record in Queensland for electricity.

Land defenders: will the Cáceres verdict break the ‘cycle of violence’ in Honduras?

Conviction of businessman who conspired in murder of indigenous rights activist Berta Cáceres raises hopes of end to impunity

When Bertha Zuñiga heard that a former Honduran army intelligence officer and businessman had been found guilty of collaborating in the murder of her mother, Berta Cáceres, she breathed a big sigh of relief. Five years after the environmental campaigner was assassinated by hired hitmen, this was the verdict her family and friends had been waiting for.

“I know there is still a long road, maybe very long and very hard, but to have achieved a guilty verdict against the [former] president of a corporation, [who is] connected to the armed forces: it is unprecedented in our country,” says Zuñiga, 30.

Egypt fears hydroelectric project will restrict limited waters on which its population depends

Ethiopia has allowed a controversial dam built across the headwaters of the Nile to fill with rain water, raising tensions with Egypt and Sudan.

The huge hydroelectric project on the Blue Nile, known as the Grand Renaissance dam, is at the centre of Ethiopia’s plan to become Africa’s biggest power exporter, but Egypt fears already limited Nile waters, on which its population of more than 100 million people depends, might be restricted.

Group calls for independent review of project it says would permanently damage Kosciuszko national park

Engineers, economists, energy specialists and environmentalists are calling for a final decision on the Snowy Hydro 2.0 project to be delayed to allow an independent review, claiming it will cost far more and deliver far less than has been promised.

The group of 30 said the 2,000-megawatt pumped hydro storage project in the Snowy Mountains would permanently damage the Kosciuszko national park.

Poorly planned Amazon dam project ‘poses serious threat to life’

Operator faces choice of weakening 14km barrier or potentially devastating a biodiversity hotspot

The biggest hydroelectric project in the Amazon rainforest has a design flaw that poses a “very serious” threat to human life and globally important ecosystems, according to documents and expert testimony received by the Guardian.

The studies suggest engineers failed to anticipate the impact of water shortages on the Pimental dam at Belo Monte, which has been closed and turned into a barrier. This is forcing the operators to choose between a structural weakening of the 14km-wide compacted-earth barrier and a reallocation of water in the reservoir or on the Xingu river, which is home to indigenous communities, fishing villages and some of the world’s most endangered species.

Ancient Turkish town begins to disappear underwater – in pictures

Posted on by

The small town of Hasankeyf, in Turkey’s Kurdish-majority south-east, is doomed to disappear in the coming months after being inhabited for 12,000 years. An artificial lake, part of the Ilısu hydroelectric dam project, will swallow it up. The huge dam, Turkey’s second largest, is being filled further down the Tigris River, despite protests that it will displace thousands of people and risks creating water shortages downstream, namely in Iraq. Residents are being moved from the ancient town to New Hasankeyf nearby, while historic artefacts have also been transported out of the area
