Which of these states do you think buy in on the Lazard calculation?
Must be Arkansas?
Yet again, the real world results completely contradict the theoretical models that Chuck presents in his repetitive cut and pastes.
It must be the real world results that are wrong though, couldn't possibly be Chuck's theoretical propaganda.
Lazard LCOE looks at the costs for new generation, not existing legacy generation. Generation capacity has to increase. So what are the best and lower cost ways to increase capacity while providing affordable, stable supply with low carbon emissions? Lazard provides some of that information in their LCOE.
And that's why Transalta is bullish on renewables.
Solar PV utility scale $24 - $96 per MWh
Solar plus storage utility scale $46-$102 per MWh
Wind Onshore $24 - $75 per MWh Gas Peaking $115 - $221 per MWh Nuclear $141 - $221 per MWh
I see Crypto stuck his foot in his mouth claiming that the Unkrainian Canada trade agreement imposes a carbon tax on the Ukraine! Wrong!
The Ukraine already has a small carbon tax. They need a carbon tax to join the EU.
And the trade agreement with Canada doesn't impose one according to the agreement and the Ukrainian Embassy.
But Crypto assumes that everyone will fall for his lies and the result is the Conservatives look like they don't support the Ukraine.
And they are so obsessed with a carbon tax that they forget Saskatchewan and Alberta also have a carbon tax on larger emitters, with no plan to remove it.
And why isn't Saskatchewan cutting the PST and fuel tax like Manitoba, if they claim they are serious about affordability?
What's good for the goose should be good for the gander.

According to the AESO the average Wind capacity factor over the last 5 years is 34%. They don’t give one for Solar but I believe it is around 16%. The solar projects I have seen proposed with storage state they have enough storage for 1-2 hours. So in your above prices with wind as an example what does the electricity cost for the 66% of the time wind isn’t producing? Or conversely to compete with natural gas or nuclear what does a 24 hr. a day 365 days a year Solar or wind project actually cost per kwh??
Even gas plants and nuclear don't run 100% of the time as they get shutdown for maintenance and breakdowns.
LCOE are lifetime measurements.
"To calculate the LCOE, we need to take the present value of all costs associated with generating 1 kWh of electricity by a given system and divide it by the total number of kilowatt hours generated over the system's lifetime."

While we wait patiently for Chuck to answer this simple question, I will repeat how this is being done on remote oil and gas sites.
My neighbor is installing standalone solar with storage power sources for running the chemical pumps on oil wells not connected to the grid.
This is in Northern US and into canada.
They have established that they need to install three full months of storage in order for a solar system to provide reliable uninterrupted power.
I assume that is what Chuck is referring to when he quotes the cost of solar with storage, coming in at $46 per megawatt.
Anything less then 3 months would be virtue signaling window dressing.
Just waiting for him to provide the source of where this has been done.
I have infinite patience.
Solar on its own is not feasible unless it can produce ammonia and or hydrogen in sufficient quantities or massive amounts of long term storage. Paired with hydro, wind, and fossil fuels and maybe some nuclear it can reduce carbon emissions as is happening in Alberta.
Solar and wind are supplemental generation sources and don't have to replace all other sources to be valuable generation sources.
The LCOE shows that solar and wind are cheaper sources of generation over their lifetime than almost anything else. They don't have to cover all our needs to be valuable and effective at providing electricity.
"There's no maximum percentage of renewables per se, it's more a question of what portfolio gives you both cheap energy and sufficiency capacity when you need it."
From one of the Alberta energy economists who studies Alberta's system.
Meanwhile , China is building one new BIG coal generator every week and the green tree huggers in BC (promoting carbon tax) are supplying the coal . What a sick fu k en joke
China on course to hit wind and solar power target five years ahead of time
Beijing bolstering position as global renewables leader with solar capacity more than rest of world combined

China is shoring up its position as the world leader in renewable power and potentially outpacing its own ambitious energy targets, a report has found. China is set to double its capacity and produce 1,200 gigawatts of energy through wind and solar power by 2025, reaching its 2030 goal five years ahead of time, according to the report by Global Energy Monitor, a San Francisco-based NGO that tracks operating utility-scale wind and solar farms as well as future projects in the country.
It says that as of the first quarter of the year, China’s utility-scale solar capacity has reached 228GW, more than that of the rest of the world combined. The installations are concentrated in the country’s north and north-west provinces, such as Shanxi, Xinjiang and Hebei.
In addition, the group identified solar farms under construction that could add another 379GW in prospective capacity, triple that of the US and nearly double that of Europe.
China has also made huge strides in wind capacity: its combined onshore and offshore capacity now surpasses 310GW, double its 2017 level and roughly equivalent to the next top seven countries combined. With new projects in Inner Mongolia, Xinjiang, Gansu and along coastal areas, China is on course to add another 371GW before 2025, increasing the global wind fleet by nearly half.
“This new data provides unrivalled granularity about China’s jaw-dropping surge in solar and wind capacity,” said Dorothy Mei, a project manager at Global Energy ([url]https://www.theguardian.com/environment/energy[/url]) Monitor. “As we closely monitor the implementation of prospective projects, this detailed information becomes indispensable in navigating the country’s energy landscape.”
The findings are in line with previous reports and government data released ([url]https://www.scmp.com/business/china-business/article/3221970/solar-jump-renewable-energy-driving-seat-home-and-abroad-chinas-capacity-just-keeps-expanding[/url]) this year, which predicted that China could easily surpass its target of supplying a third of its power consumption through renewable sources by 2030.
China’s green energy drive is part of its effort to meet dual carbon goals set out in 2020. As the world’s second largest economy, it is the biggest emitter of greenhouse gases and accounts for half of the world’s coal consumption. The Chinese president, Xi Jinping, pledged in 2020 to achieve peak CO2 emissions before 2030 and carbon neutrality by 2060.
The report attributed China’s remarkable progress in expanding its non-fossil energy sources to the range of policies its government has implemented, including generous subsidies to incentivise developers as well as regulations to put pressure on provincial governments and generating companies.
China began operating the world’s largest hybrid solar-hydro power plant in the Tibetan plateau on Sunday. Named Kela, the plant can produce 2bn kW hours of electricity annually, equal to the energy consumption of more than 700,000 households.
Itis only the first phase of a massive clean energy project in the Yalong River basin. The installation has a 20GW capacity now and is expected to reach about 50GW by 2030. skip past newsletter promotion ([url]https://www.theguardian.com/world/2023/jun/29/china-wind-solar-power-global-renewable-energy-leader#EmailSignup-skip-link-13[/url]) Sign up to Down to Earth
