Disturbance of archaeological sites is a possibility during the construction of the city's massive new hybrid gas-solar power plant north of the airport.

At a recent meeting designed to resolve air-quality, water-quality, wildlife and cultural issues, officials with the California Energy Commission outlined three sites that need to be examined and secured before construction can proceed. The 563-megawatt project, to be built on 388 acres, would meet the electricity needs of about half a million people, providing energy directly to Southern California's grid.

The solar component will take up 250 acres. One site is a prehistoric area dating back 4,000 years that contains "trackways" of human and animal footprints dried in the clay about a foot under the earth's surface, said Mike Lerch, a consultant with the CEC who is tackling the cultural aspect of the permitting process.

Victorville, as the applicant in the process, had recommended that the sites were not significant, according to a CEC report, adding that such a recommendation was based on superficial observation alone and that greater scrutiny was needed.

The other two sites are pre-1952 houses, and all three "could have subsurface deposits that could yield data important in history or prehistory," according to a CEC report. The exact location of the three sites is confidential for their protection, Lerch said. The Mojave footprint site is currently deeded to the San Bernardino County Museum, he added. The site is near the water reclamation line at the Victor Valley Wastewater Reclamation Authority, which is set to provide reclaimed water to cool the power plant's heating tower.

The Mojave's footprint sites have features that stand out among cultural sites in the United States, Lerch said, referring to the way the footprints are preserved. The CEC does not have information exactly how far the footprints extend, so the next step is to take an accounting of what is really out there. "We don't want to disturb anything so we try to work around it," Lerch said.

Archeological sites were not the only things on the minds of those who attended the meeting. Frank Chaves, feeling a little outnumbered, appeared to be the only landowner who attended. He owns 160 acres on or near the site for the power plant.

Already he has sold a right-of-way to Victorville to install infrastructure. "I'd like to keep our property but what do we do?" said Chaves, a real estate investor who was hoping to develop the land for industrial use. The trading of pollution credits is still under scrutiny by the CEC.

One official noted that both volatile organic compounds and nitrous oxide are related to depletion of the ozone layer. Victorville 2 needs about 50 tons per year of VOCs and 150 tons per year of NOx . Translated to credits that amount to about 455 tons per year, meaning the city will be paying about $3.5 million to the South Coast Air Quality Management District to get the credits.

Electricity prices spike in Alberta

Alberta electricity price spike drives 25% CPI surge amid heatwave demand, coal-to-gas conversions, hydro shortfalls, and outages; consumers weigh fixed-rate plans, solar panels, home retrofits, and variable rates to manage bills and grid volatility.

 

Key Points

A recent 25% monthly rise in Alberta power prices driven by heatwave demand, constraints, outages, and fuel shifts.

✅ Heatwave pushed summer peak demand near record

✅ Coal-to-gas conversions and outages tightened supply

✅ Fixed-rate plans, solar, retrofits can reduce bill risk

 

Albertans might notice they are paying more when the next electricity bill comes in as bills on the rise in Calgary alongside provincial trends.

According to the consumer price index, Alberta saw its largest monthly increase since July 2015 as the price of electricity in Alberta rose 25 per cent amid rising electricity prices across the province.

“So I paid negative $70 last month. I actually made money. To supply power to the grid,” said Conrad Nobert, with Climate Action Edmonton.

Norbert is an environmental activist who favours solar power and is warning that prices will continue to go up along with the rising effects from climate change.

“My thoughts are that we can mitigate the price of power going up by taking climate action.”

Alberta experienced one of the hottest summers on record and many people were left scrambling to buy air conditioners.

That demand, along with a number of other factors, drove up prices, prompting some households to lock in rates for protection, says an assistant professor at the University of Calgary who teaches electricity systems.

“At the end of June, during the heatwave, we were a couple megawatts shy of setting an all-time record demand for electricity in the province. That would have been the first time that record for demand in the summer. Traditionally Alberta is a winter peaking province, as shown by an electricity usage record during a deep freeze not long ago,” explained Sara Hastings Simon, an assistant professor at the University of Calgary.

Other reasons for the spike: Alberta’s continuing shift from coal to natural-gas-fired power and changes to electricity production and pricing across the market.

There are a few ways consumers can save money on their power bill; installing solar panels and retrofitting your home to opting for a fixed-rate plan, or considering protections like a consumer price cap where applicable.

“So by default, people are put into a variable rate plan, that changes month to month and that helps to manage prices so you don’t get that big surprise at where prices might be. I think we will get a lot more people looking at that option.”

A statement provided by Dale Nally, Alberta’s Associate Minister of natural gas and electricity, noted recent policy changes including the carbon tax repeal and price cap now in place that affect consumers, says in part:

“This period of high market prices is driven by low supplies of hydro-generated electricity from British Columbia and the pacific northwest, scheduled outages for coal-gas-conversions, unplanned infrastructure outages and unprecedented, and record-breaking high demand due to hot weather. We expect some of the factors that have caused recent increases in prices will be short-term.”

India’s Kakrapur 3 achieves criticality

Kakrapar Unit 3 700MWe PHWR achieved first criticality, showcasing indigenously designed nuclear power, NPCIL operations, Make in India manufacturing, advanced safety systems, grid integration, and closed-fuel-cycle strategy for India's expansion of pressurised heavy water reactors.

 

Key Points

India's first indigenous 700MWe PHWR at Kakrapar reached criticality, advancing NPCIL's Make in India nuclear power.

✅ First indigenous 700MWe PHWR achieves criticality

✅ NPCIL-built, Make in India components and contractors

✅ Advanced safety: passive decay heat removal, containment spray

 

Unit 3 of India’s Kakrapar nuclear plant in Gujarat achieved criticality on 22 July, as milestones at nuclear projects worldwide continue to be reached. It is India’s first indigenously designed 700MWe pressurised heavy water reactor (PHWR) to achieve this milestone.

Prime Minister Narendra Modi congratulated nuclear scientists, saying the reactor is a shining example of the 'Make in India' campaign and of the government's steps to get nuclear back on track in recent years, and a trailblazer for many such future achievements. 

India developed its own nuclear power generation technology as it faced sanctions from the international community following its first nuclear weapons test in in 1974. It has not signed the Nuclear Non-Proliferation Treaty, while China's nuclear energy development is on a steady track according to experts. India has developed a three-stage nuclear programme based on a closed-fuel cycle, where the used fuel of one stage is reprocessed to produce fuel for the next stage.

Kakrapar 3 was developed and is operated by state-owned Nuclear Power Corporation of India Ltd (NPCIL), while in Europe KHNP considered for a Bulgarian project as countries weigh options. The first two units are 220MWe PHWRs commissioned in 1993 and 1995. NPCIL said in a statement that the components and equipment for Kakrapur 3 were “manufactured by lndian industries and the construction and erection was undertaken by various lndian contractors”.

The 700MWe PHWRs have advanced safety features such as steel lined inner containment, a passive decay heat removal system, a containment spray system, hydrogen management systems etc, the statement added.

Fuel loading was completed by mid-March, a crucial step in Abu Dhabi during its commissioning as well. “Thereafter, many tests and procedures were carried out during the lockdown period following all COVlD-19 guidelines.”

“As a next step, various experiments / tests will be conducted and power will be increased progressively, a path also followed by Barakah Unit 1 reaching 100% power before commercial operations.” Kakrapur 3 will be connected to the western grid and will be India’s 23rd nuclear power reactor.

Kakrapur 3 “is the front runner in a series of 16 indigenous 700MWe PHWRs which have been accorded administrative approval and financial sanction by the government and are at various stages of implementation”. Five similar units are under construction at Kakarapur 4, Rajasthan 7&8 and Gorakhpur1&2.

DAE said in January 2019 that India planned to put 21 new nuclear units with a combined generating capacity of 15,700MWe into operation by 2031, including ten indigenously designed PHWRs, while Bangladesh develops nuclear power with IAEA assistance.

Cheap material converts heat to electricity

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

 

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

 

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

Iran eyes transmitting electricity to Europe as region’s power hub

Iran Electricity Grid Synchronization enables regional interconnection, cross-border transmission, and Caspian-Europe energy corridors, linking Iraq, Azerbaijan, Russia, and Qatar to West Asia and European markets with reliable, flexible power exchange.

 

Key Points

Iran's initiative to link West Asian and European power grids for trade, transit, reliability, and regional influence.

✅ Synchronizes grids with Iraq, Azerbaijan, Russia, and potential Qatar link

✅ Enables east-to-Europe electricity transit via Caspian energy corridors

✅ Backed by gas-fueled and combined-cycle generation capacity

 

Following a plan for becoming West Asia’s electricity hub, Iran has been taking serious steps for joining its electricity network with neighbors in the past few years.

The Iranian Energy Ministry has been negotiating with the neighboring countries including Iraq for the connection of their power networks with Iran, discussing Iran-Iraq energy cooperation as well as ties with Russia, Afghanistan, Azerbaijan, and Qatar to make them enable to import or transmit their electricity to new destination markets through Iran.

The synchronization of power grids with the neighboring countries, not only enhances Iran’s electricity exchanges with them, but it will also increase the political stance of the country in the region.

So far, Iran’s electricity network has been synchronized with Iraq, where Iran is supplying 40% of Iraq's power today, and back in September, the Energy Minister Reza Ardakanian announced that the electricity networks of Russia and Azerbaijan are the next in line for becoming linked with the Iranian grid in the coming months.

“Within the next few months, the study project of synchronization of the electricity networks of Iran, Azerbaijan, and Russia will be completed and then the executive operations will begin,” the minister said.

Meanwhile, Ardakanian and Qatari Minister of State for Energy Affairs Saad Sherida Al-Kaabi held an online meeting in late September to discuss joining the two countries' electricity networks via sea.

During the online meeting, Al-Kaabi said: "Electricity transfer between the two countries is possible and this proposal should be worked on.”

Now, taking a new step toward becoming the region’s power hub, Iran has suggested becoming a bridge between East and Europe for transmitting electricity.

In a virtual conference dubbed 1st Caspian Europe Forum hosted by Berlin on Thursday, the Iranian energy minister has expressed the country’s readiness for joining its electricity network with Europe.

"We are ready to connect Iran's electricity network, as the largest power generation power in West Asia, with the European countries and to provide the ground for the exchange of electricity with Europe," Ardakanian said addressing the online event.

Iran's energy infrastructure in the oil, gas, and electricity sectors can be used as good platforms for the transfer of energy from east to Europe, he noted.

In the event, which was aimed to study issues related to the development of economic cooperation, especially energy, between the countries of the Caspian Sea region, the official added that Iran, with its huge energy resources and having skilled manpower and advanced facilities in the field of energy, can pave the ground for the prosperity of international transport and energy corridors.

"In order to help promote communication between our landlocked neighbors with international markets, as Uzbekistan aims to export power to Afghanistan across the region, we have created a huge transit infrastructure in our country and have demonstrated in practice our commitment to regional development and peace and stability," Ardakanian said.

He pointed out that having a major percentage of proven oil and gas resources in the world, regional states need to strengthen relations in a bid to regulate production and export policies of these huge resources and potentially play a role in determining the price and supply of these resources worldwide.

“EU countries can join our regional cooperation in the framework of bilateral or multilateral mechanisms such as ECO,” he said.

Given the growing regional and global energy needs and the insufficient investment in the field, with parts of Central Asia facing severe electricity shortages today, as well as Europe's increasing needs, this area can become a sustainable area of cooperation, he noted.

Ardakanian also said that by investing in energy production in Iran, Europe can meet part of its future energy needs on a sustainable basis.

In Iraq, plans for nuclear power plants are being pursued to tackle chronic electricity shortages, reflecting parallel efforts to diversify generation.

Iran currently has electricity exchange with Armenia, Azerbaijan, Iraq, where grid rehabilitation deals have been finalized, Turkmenistan, and Afghanistan.

The country’s total electricity exports vary depending on the hot and cold seasons of the year, since during the hot season which is the peak consumption period, the country’s electricity exports decreases, however electrical communication with neighboring countries continues.

Enjoying abundant gas resources, which is the main fuel for the majority of the country’s power plants, Iran has the capacity to produce about 85,500 megawatts [85.5 gigawatts (GW)] of electricity.

Currently, combined cycle power plants account for the biggest share in the country’s total power generation capacity as Iran is turning thermal plants to combined cycle to save energy, followed by gas power plants.

Tube Strikes Disrupt London Economy

London Tube Strikes Economic Impact highlights transport disruption reducing foot traffic, commuter flows, and tourism, squeezing small businesses, hospitality revenue, and citywide growth while business leaders urge negotiations, resolution, and policy responses to stabilize operations.

 

Key Points

Reduced transport options cut foot traffic and sales, straining small businesses and slowing London-wide growth.

✅ Hospitality venues report lower revenue and temporary closures

✅ Commuter and tourism declines reduce daily sales and bookings

✅ Business groups urge swift negotiations to restore services

 

London's economy is facing significant challenges due to ongoing tube strikes, challenges that are compounded by scrutiny of UK energy network profits and broader cost pressures across sectors, with businesses across the city experiencing disruptions that are impacting their operations and bottom lines.

Impact on Small Businesses

Small businesses, particularly those in the hospitality sector, are bearing the brunt of the disruptions caused by the strikes. Many establishments rely on the steady flow of commuters and tourists that the tube system facilitates, while also hoping for measures like temporary electricity bill relief that can ease operating costs during downturns. With reduced transportation options, foot traffic has dwindled, leading to decreased sales and, in some cases, temporary closures.

Economic Consequences

The strikes are not only affecting individual businesses but are also having a ripple effect on the broader economy, a dynamic seen when commercial electricity consumption plummeted in B.C. during the pandemic. The reduced activity in key sectors is contributing to a slowdown in economic growth, echoing periods when BC Hydro demand fell 10% and prompting policy responses such as Ontario electricity rate reductions for businesses, with potential long-term consequences if the disruptions continue.

Calls for Resolution

Business leaders and industry groups are urging for a swift resolution to the strikes. They emphasize the need for dialogue between the involved parties to reach an agreement that minimizes further economic damage and restores normalcy to the city's transportation system.

The ongoing tube strikes in London are causing significant disruptions to the city's economy, particularly affecting small businesses that depend on the efficient movement of people. Immediate action is needed to address the issues, drawing on tools like a subsidized hydro plan used elsewhere to spur recovery, to prevent further economic downturn.

California's future with income-based flat-fee utility bills is getting closer

California Income-Based Utility Fees would overhaul electricity bills as CPUC weighs fixed charges tied to income, grid maintenance costs, AB 205 changes, and per-kilowatt-hour rates, shifting from pure usage pricing to hybrid utility rate design.

 

Key Points

Income-based utility fees are fixed monthly charges tied to earnings, alongside per-kWh rates, to help fund grid costs.

✅ CPUC considers fixed charges by income under AB 205

✅ Separates grid costs from per-kWh energy charges

✅ Could shift rooftop solar and EV charging economics

 

Electricity bills in California are likely to change dramatically in 2026, with major changes under discussion statewide.

The California Public Utilities Commission (CPUC) is in the midst of an unprecedented overhaul of the way most of the state’s residents pay for electricity, as it considers revamping electricity rates to meet grid and climate goals.

Utility bills currently rely on a use-more pay-more system, where bills are directly tied to how much electricity a resident consumes, a setup that helps explain why prices are soaring for many households.

California lawmakers are asking regulators to take a different approach, and some are preparing to crack down on utility spending as oversight intensifies. Some of the bill will pay for the kilowatt hours a customer uses and a monthly fixed fee will help pay for expenses to maintain the electric grid: the poles, the substations, the batteries, and the wires that bring power to people’s homes.

The adjustments to the state’s public utility code, section 739.9, came about because of changes written into a sweeping energy bill passed last summer, AB 205, though some lawmakers now aim to overturn income-based charges in subsequent measures.

A stroke of a pen, a legislative vote, and the governor’s signature created a move toward unprecedented income-based fixed charges across the state.

“This was put in at the last minute,” said Ahmad Faruqui, a California economist with a long professional background in utility rates. “Nobody even knew it was happening. It was not debated on the floor of the assembly where it was supposedly passed. Of course, the governor signed it.”

Faruqui wonders who was responsible for legislation that was added to the energy bill during the budget writing process. That process is not transparent.

“It’s a very small clause in a very long bill, which is mostly about other issues,” Faruqui said.

But that small adjustment could have a massive impact on California residents, because it links the size of a monthly flat fee for utility service to a resident’s income. Earn more money and pay a higher flat fee.

That fee must be paid even before customers are charged for how much power they draw.

Regulators interpreted legislative change as a mandate, but Faruqui is not sold.

“They said the commission may consider or should consider,” Faruqui said. “They didn’t mandate it. It’s worth re-reading it.”

In fact, the legislative language says the commission “may” adopt income-based flat fees for utilities. It does not say the commission “should” adopt them.

Nevertheless, the CPUC has already requested and received nine proposals for how a flat fee should be implemented, as regulators face calls for action amid soaring electricity bills.

The suggestions came from consumer groups, environmentalists, the solar industry and utilities.
