Are renewables cheaper? Here’s the cost of the alternative

Australians have consistently been told renewables would be cheaper but between 2021 and 2024 household electricity tariffs spiked by around a third.

This uncomfortable fact has been seized on by many to argue the price of the energy transition is too high.

But what if Australia’s energy market had a sliding doors moment at the start of the decade, and instead of renewables, new market entrants were coal and gas-fired generators?

New analysis finds while coal and gas were once unambiguously the National Electricity Market’s lowest cost entrants, sticking with them would see wholesale market costs and prices ~30-50% higher.

Expert view

"The modelling shows recent investment commitments comprising wind, solar, gas turbines, and storage assets present as lowest cost. This should come as no surprise — If there was a lower cost alternative, forward prices would be pointing southwards towards such an outcome, and energy companies would be investing in these alternate supply options. But this is not the case.

Governments can always alter economic gravity in energy markets by underwriting specific plants, old coal or new renewables, using taxpayer funds. But policymakers should work with capital markets and supply chains which are under pressure from equity and debt capital markets to decarbonise.

Conversely, capital markets and supply chains need to acknowledge the political economy of stable electricity prices and the reliability of supply – the market is not ready for a procession of incumbent coal plant exits.”

Finding a future for energy-intensive industry

Doubt over the future of Glencore’s Mount Isa copper smelter and broader supply chain prompted high-level talks with federal and state government ministers in the outback city.

“The Mount Isa copper smelter is a cornerstone of Queensland’s economy and supports the viability of nationally significant supply chain infrastructure like the Mount Isa to Townsville rail line and the Port of Townsville. But we can’t make decisions for Glencore. We are continuing to engage in good faith with Glencore, and we expect Glencore to do the same,” Queensland Minister for Natural Resources and Mines Dale Last said after Friday’s talks.

“The Australian Government is closely monitoring the situation at the Mount Isa copper smelter and we are committed to working with the Queensland Government on the best path forward. As a vital industrial site for the Mount Isa community and the broader region, any closure of the Mount Isa copper smelter would have a detrimental impact on Australia’s sovereign capability and other facilities downstream that rely on the smelter.” — Federal Minister for Industry Tim Ayres

Glencore has requested financial support to keep the smelter viable, citing market conditions, high energy costs, and a shortage of copper concentrates.

“We want to keep the Mount Isa Smelter and Townsville Refinery in operation and are working with all levels of government, to weather the challenges of uncertain global markets and high costs in Australia, particularly gas and energy,” Glencore has said.

COP30 expectation management heats up

Physicist and climate scientist Bill Hare handed a letter from over 250 scientists to Brazilian President Luiz Inácio Lula da Silva to champion “a fast, fair, effective, and full phaseout of fossil fuels” in the lead-up to the COP30 climate talks in Brazil, which mark the 10-year anniversary of the Paris Agreement.

Aiming to bolster global climate efforts following the US withdrawal from the Paris Agreement, Brazil has proposed expanding emissions reduction commitments to include pledges from non-state actors - companies, states, and cities. (Reuters)

Countries are being urged by the United Nations to submit updated emissions reduction targets by September after many, including Australia, missed a February deadline.

Brazil’s president and UN Secretary-General Antonio Guterres hosted 17 leaders of large economies and small islands to a closed online meeting to talk about stronger commitments for their 2035 emission targets.

Meanwhile Brazil is expanding its oil and gas exploration and production to boost the economy. (Oil Price)

Roiled markets are primed, with investors considering all scenarios. “We have completed our very successful attack on three nuclear sites in Iran … A full payload of BOMBS was dropped on the primary site, Fordow,” US President Donald Trump posted, calling for peace.

Any closure or threat to the Strait of Hormuz, through which nearly 20% of the world’s oil flows, would send prices sharply higher. Some analysts warn crude could spike toward US$130 per barrel, depending on Iran’s next move.

“That fundamentally changes the landscape for equity sectors, currencies, and credit,” Nigel Green, CEO of financial advisory giant deVere Group, said in an email. At the same time, there is likely to be “increased investor appetite” for oil and gas producers, while utility companies, with stable earnings profiles and pricing power, may also draw inflows in this higher-volatility environment, he said.

Private equity players are considering the possibility of bankrolling a merger between two Australian energy giants, the AFR’s Chanticleer reported. EnergyAustralia and Alinta Energy were cited given they‘ve both been open to deals in recent years, with past talks that have reportedly happened between the companies failing to find a worthwhile transaction.


Projects

A pilot project to convert a whole neighbourhood from gas to electricity has just completed its first stage. The Australian Renewable Energy Agency subsidised upfront costs, while Endeavour Energy is monitoring how best to manage energy loads. It's hoped the project will become a blueprint for making the most of community energy resources nationwide. (ABC)

Federal ministers are at odds over an NT gas pipeline decision, according to a brief released under FOI laws, about APA Group’s (ASX: APA) plan to build a pipeline to connect a fracking operation in the Beetaloo gas basin with the existing Amadeus pipeline. (The Guardian)


Policy

A Politico analysis identified almost 800 clean electricity generation projects, mostly in Republican areas, that could lose subsidies as the US Senate debates changes to the House megabill.

Joining a growing list of European economies, Ireland ended coal generation with the closure of Moneypoint Power Stations in County Clare, which has been repurposed as a backup oil-fired plant until 2029. Onshore and offshore wind will increasingly become Moneypoint’s focus, with the existing deep water port and other infrastructure to underpin what will become one of Ireland’s largest renewable energy hubs.

Regulation

The Australian Energy Regulator approved capital expenditure of $45.7 million for ElectraNet to undertake Stage 1a early works at its Mid North South Australia Renewable Energy Zone. The project cost will add an estimated $0.56 per annum to residential electricity bills in South Australia.


Technology

Already living the future, in a purpose-built sustainable estate on Victoria’s Bass Coast every home is powered without gas, using rooftop solar and passive solar design principles, and achieves an average 8-star NatHERS energy rating, which is well above the national average. (Yahoo)

While Goldman Sachs, Microsoft, and Amazon herald Small Modular Reactors as the solution to everything from AI’s energy hunger to coal’s decline, the nuclear vendors themselves won’t promise atomic power will be cheaper than renewables, writes nuclear veteran Arnie Gundersen.

Climate

The energy transition has become a key cornerstone underlying the EU's climate strategy, the European Green Deal, which requires developing a power system largely based on variable renewable electricity (VRE). Untapped geographic potentials of VRE remain large in Europe, according to research published in Advances in Applied Energy, which also assessed intercountry risk of concurrent renewable energy droughts.

Partner at Copenhagen Infrastructure Partners and Chief Commercial Officer at Stiesdal Offshore Mark Hannibal was appointed chair of the Global Wind Energy Council (GWEC).

“Wind energy delivers clean and secure energy and is critical to avoiding a climate catastrophe. It is an honour to support GWEC on its mission, and to advocate for the wind industry on the global stage. I would also like to congratulate my predecessor Jonathan Cole for his excellent leadership through the previous two years.” — CWEC Chair Mark Hannibal

Research

Emissions from LNG supply could be cut by more than 60% using today’s technologies, the International Energy Agency said, as it delivered new analysis on greenhouse gas emissions from across the global LNG supply chain.

The analysis covers 350 upstream assets in 22 countries including Australia, finding they emit roughly 350 million tonnes of carbon dioxide equivalent annually. The Agency said while LNG results in about 25% less emissions than coal, comparing it only to coal – the most carbon-intensive fuel – sets the bar too low, especially given the opportunities already available for improving the emissions performance of LNG supply. It called out Australia’s “strong geographic and regulatory advantages” for integrating carbon capture and storage with LNG production.
