Central China faces power deficit

Texas Power Grid Blackouts loom as ERCOT forecasts record air conditioning load, tight reserve margins, peak demand spikes, and rising natural gas prices; heatwaves could trigger brownouts without added solar, storage, and demand response.

Key Points

Texas Power Grid Blackouts are outages when AC-driven peak demand and ERCOT reserves outstrip supply during heatwaves.

✅ ERCOT forecasts record AC load and tight reserve margins.

✅ Coal retirements cut capacity; gas and solar additions lag.

✅ Peak prices, brownouts likely without storage and demand response.

U.S. Air conditioning related electricity usage will break records and may cause blackouts across the U.S. and in Texas this summer. Power grid operators are forecasting that electricity supplies will exceed demands during the summer months.

Most of Texas will face severe electricity shortages because of hot temperatures, air conditioning, and a strong economy, with millions at risk of electricity shut-offs during extreme heat, Bill Magness the president of the Electric Reliability Council of Texas (ERCOT) told the Associated Press. Magness thinks the large numbers people moving to Texas for retirement will increase the demand for air conditioning and electricity use. Retired people are more likely to be home during the day when temperatures are high – so they are more likely to turn up the air conditioner.

Around 50% of all electricity in Texas is used for air conditioning and 100% of homes in Texas have air conditioners, Forbes reported. That means just a few hot days can strain the grid and a heatwave can trigger brownouts and blackouts, in a system with more blackouts than other developed countries on average.

The situation was made worse by Vistra Energy’s decision to close more coal-fired power plants last year, The Austin American Statesman reported. The closed plants; Big Brown, Sadow, and Monticello, generated around 4,100 megawatts (4.1 million watts) of electricity, enough generation capacity to power two million homes, The Waco Herald-Tribune reported.

Texas Electric Grid Might Not Meet Demand

Texas’s grid has never operated without those plants will make this summer a test of its capacity. Texas only has a 6% reserve of electricity that might fall will because of problems like downed lines or a power plant going offline.

A Vistra subsidiary called Luminant has added around 8,000 megawatts of generation capacity from natural-gas burning plants, The Herald-Tribune reported. Luminant also plans to open a giant solar power plant in Texas to increase grid capacity.

The Texas grid already reached peak capacity in May because of unexpectedly high demand and technical problems that reflect more frequent outages in many states, Houston Public Media reported. Grid capacity fell because portions of the system were offline for maintenance.

Some analysts have suggested starting schools after Labor Day to shift peak August demand, potentially easing stress on the grid.

Electricity Reserves are Tight in Texas

Electricity reserves will be very tight on hot summer days in Texas this summer, Magness predicted. When the thermometer rises, people crank up the air conditioner which burns more electricity.

The grid operator ERCOT anticipates that Texas will need an additional 1,600 megawatts of electricity this summer, but record-high temperatures can significantly increase the demand. If everything is running correctly, Texas’s grid can produce up to 78,184 megawatts of electricity.

“The margin between absolute peak power usage and available peak supply is tighter than in years past,” Andrew Barlow, a spokesman for Texas’s Public Utility Commission admitted.

Around 90% of Texas’s grid has enough generating capacity, ERCOT estimated. That means 10% of Texas’s power grid lacks sufficient generating capacity which increases the possibility of blackouts.

Even if the electricity supply is adequate electricity prices can go up in Texas because of higher natural gas prices, Forbes reported. Natural gas prices might go up over the summer because of increased electricity demands. Texas uses between 8% and 9% of America’s natural gas supply to generate electricity for air conditioning in the summer.

Be Prepared For Blackouts This Summer.

Texas’s problems might affect other regions including neighboring states such as Oklahoma, Arkansas, Louisiana, and New Mexico and parts of Mexico, as lawmakers push to connect Texas’s grid to the rest of the nation to improve resilience because those areas are connected to the same grid. Electricity from states like Colorado might be diverted to Texas in case of power shortages there.

Beyond the U.S., Canadian electricity grids are increasingly exposed to harsh weather that can ripple across markets as well.

Home and business owners can avoid summer blackouts by tapping sources of Off-Grid electricity. The two best sources are backup battery storage and solar panels which can run your home or business if the grid runs dry.

If you have family members with health problems who need air conditioning, or you rely on a business or freelance work that requires electricity for income, backup power is vital. Those who need backup electricity for their business should be able to use the expense of installing it as a tax deduction.

Having backup electricity available might be the only way for Texans to keep cool this summer.

Hydro One investment risk reflects Ontario government influence, board shakeup, Avista acquisition uncertainty, regulatory hearings, dividend growth prospects, and utility M&A moves in Peterborough, with stock volatility since the 2015 IPO.

Key Points

Hydro One investment risk stems from political control, governance turnover, regulatory outcomes, and uncertain M&A.

✅ Ontario retains near-50% stake, affecting autonomy and policy risk

✅ Board overhaul and CEO exit create governance uncertainty

✅ Avista deal, OEB hearings, local utility M&A drive outcomes

Hydro One may be only half-owned by the province on Ontario but that’s enough to cause uncertainty about the company’s future, thus making for an investment risk, says Douglas Kee of Leon Frazer & Associates.

Since its IPO in November of 2015, Hydro One has seen its share of ups and downs, including a Q2 profit decline earlier this year, mostly downs at this point. Currently trading at $19.87, the stock has lost 11 per cent of its value in 2018 and 12 per cent over the last 12 months, despite a one-time gain boosting Q2 profit that followed a court ruling.

This year has been a turbulent one, to say the least, as newly elected Ontario premier Doug Ford made good this summer on his campaign promise re Hydro One by forcing the resignation of the company’s 14-person board of directors along with the retirement of its chief executive, an event that saw Hydro One shares fall amid the turmoil. An interim CEO has been found and a new 10-person board and chairman put in place, but Kee says it’s unclear what impact the shakeup will ultimately have, other than delaying a promising-looking deal to purchase US utility Avista Corp, with the companies moving to ask the U.S. regulator to reconsider the order.

Douglas Kee’s take on Hydro One stock

“We looked at Hydro One a couple of times two years ago and just decided that with the Ontario government’s still owning a big chunk of the company … there are other public companies where you get the same kind of yield, the same kind of dividend growth, so we just avoided it,” says Kee, managing director and chief investment officer with Leon Frazer & Associates, to BNN Bloomberg.

“The old board versus the new board, I’m not sure that there’s much of an improvement. It was politics more than anything,” he says. “The unfortunate part is that the acquisition they were making in the United States is kind of on hold for now. The regulatory procedures have gone ahead but they are worried, and I guess the new board has to make a decision whether to go ahead with it or not.”

“Their transmissions side is coming up for regulatory hearings next year, which could be difficult in Ontario,” says Kee. “The offset to that is that there are a lot of municipal distributions systems in Ontario that may be sold — they bought one in Peterborough recently, which was a good deal for them. There may be more of that coming too.”

Last month, Hydro One reached an agreement with the City of Peterborough to buy its Peterborough Distribution utility which serves about 37,000 customers for $105 million. Another deal to purchase Orillia Power Distribution Corp for $41 million has been cancelled after an appeal to the Ontario Energy Board was denied in late August. Hydro One’s sought-after Avista Corp acquisition is reported to be worth $7 billion.

Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

Nuclear Power Resilience During COVID-19 shows low-carbon electricity supporting renewables integration with grid flexibility, reliability, and inertia, sustaining decarbonization, stable baseload, and system security while prices fell and demand dropped across markets.

Key Points

It shows nuclear plants providing reliable, low-carbon power and supporting grid stability despite demand declines.

✅ Low prices challenge investment; lifetime extensions are cost-effective.

✅ Nuclear provides inertia, reliability, and dispatchable capacity.

✅ Market reforms should reward flexibility and grid services.

The COVID-19 pandemic has transformed the operation of power systems across the globe, including European responses that many argue accelerated the transition, and offered a glimpse of a future electricity mix dominated by low carbon sources.

The performance of nuclear power, in particular, demonstrates how it can support the transition to a resilient, clean energy system well beyond the COVID-19 recovery phase, and its role in net-zero pathways is increasingly highlighted by analysts today.

Restrictions on economic and social activity during the COVID-19 outbreak have led to an unprecedented and sustained decline in demand for electricity in many countries, in the order of 10% or more relative to 2019 levels over a period of a few months, thereby creating challenging conditions for both electricity generators and system operators (Fig. 1). The recent Sustainable Recovery Report by the International Energy Agency (IEA) projects a 5% reduction in global electricity usage for the entire year 2020, with a record 5.7% decline foreseen in the United States alone. The sustainable economic recovery will be discussed at today's IEA Clean Energy Transitions Summit, where Fatih Birol's call to keep options open will be prominent as IAEA Director General Rafael Mariano Grossi participates.

Electricity generation from fossil fuels has been hard hit, due to relatively high operating costs compared to nuclear power and renewables, as well as simple price-setting mechanisms on electricity markets. By contrast, low-carbon electricity prevailed during these extraordinary circumstances, with the contribution of renewable electricity rising in a number of countries as analyses see renewables eclipsing coal by 2025, due to an obligation on transmission system operators to schedule and dispatch renewable electricity ahead of other generators, as well as due to favourable weather conditions.

Nuclear power generation also proved to be resilient, reliable and adaptable. The nuclear industry rapidly implemented special measures to cope with the pandemic, avoiding the need to shut down plants due to the effects of COVID-19 on the workforce or supply chains. Nuclear generators also swiftly adapted to the changed market conditions. For example, EDF Energy was able to respond to the need of the UK grid operator by curtailing sporadically the generation of its Sizewell B reactor and maintain a cost-efficient and secure electricity service for consumers.

Despite the nuclear industry's performance during the pandemic, faced with significant decreases in demand, many generators have still needed to reduce their overall output appreciably, for example in France, Sweden, Ukraine, the UK and to a lesser extent Germany (Fig. 2), even as the nuclear decline debate continues in Europe. Declining demand in France up to the end of March already contributed to a 1% drop in first quarter revenues at EDF, with nuclear output more than 9% lower than in the year before. Similarly, Russia's Rosatom experienced a significant demand contraction in April and May, contributing to an 11% decline in revenues for the first five months of the year.

Overall, the competitiveness and resilience of low carbon technologies have resulted in higher market shares for nuclear, solar and wind power in many countries since the start of lockdowns (Fig. 3), and low-emissions sources to meet demand growth over the next three years. The share of nuclear generation in South Korea rose by almost 9 percentage points during the pandemic, while in the UK, nuclear played a big part in almost eliminating coal generation for a period of two months. For the whole of 2020, the US Energy Information Administration's Short-Term Energy Outlook sees the share of nuclear generation increasing by more than one percentage point compared to 2019. In China, power production decreased during January-February 2020 by more than 8% year on year: coal power decreased by nearly 9%, hydropower by nearly 12%. Nuclear has proved more resilient with a 2% reduction only. The benefits of these higher shares of clean energy in terms of reduced emissions of greenhouse gases and other air pollutants have been on full display worldwide over the past months.

Challenges for the future

Despite the demonstrated performance of a cleaner energy system through the crisis - including the capacity of existing nuclear power plants to deliver a competitive, reliable, and low carbon electricity service when needed - both short- and long-term challenges remain.

In the shorter term, the collapse in electricity demand has accelerated recent falls in electricity prices, particularly in Europe (Fig. 4), from already economically unsustainable levels. According to Standard and Poor's Midyear Update, the large price drops in Europe result from not only COVID-19 lockdown measures but also collapsing demand due to an unusually warm winter, increased supply from renewables in a context of lower gas prices and CO2 allowances . Such low prices further exacerbate the challenging environment faced by many electricity generators, including nuclear plants. These may impede the required investments in the clean energy transition, with longer term consequences on the achievement of climate goals.

For nuclear power, maintaining and extending the operation of existing plants is essential to support and accelerate the transition to low carbon energy systems. With a supportive investment environment, a 10-20 year lifetime extension can be realized at an average cost of US $30-40/MW*h, making it among the most cost-effective low-carbon options, while also maintaining dispatchable capacity and lowering the overall cost of the clean energy transition. The IEA Sustainable Recovery report indicates that without such extensions 40% of the nuclear fleet in developed economies may be retired within a decade, adding around US$ 80 billion per year to electricity bills. The IEA note the potential for nuclear plant maintenance and extension programmes to support recovery measures by generating significant economic activity and employment.

The need for flexibility

New nuclear power projects can provide similar economic and environmental benefits and applications beyond electricity, but will be all the more challenging to finance without strong policy support and more substantive power market reforms, including improved frameworks for remunerating reliability, flexibility and other services. The need for flexibility in electricity generation and system operation - a trend accelerated by the crisis - will increasingly characterize future energy systems over the medium to longer term.

Looking further ahead, while generators and system operators successfully responded to the crisis, the observed decline in fossil fuel generation draws attention to additional grid stability challenges likely to emerge further into the energy transition. Heavy rotating steam and gas turbines provide mechanical inertia to an electricity system, thereby maintaining its balance. Replacing these capacities with variable renewables may result in greater instability, poorer power quality and increased incidence of blackouts. Large nuclear power plants along with other technologies can fill this role, alleviating the risk of supply disruptions in fully decarbonized electricity systems.

The challenges created by COVID-19 have also brought into focus the need to ensure resilience is built-in to future energy systems to cope with a broader range of external shocks, including more variable and extreme weather patterns expected from climate change.

The performance of nuclear power during the crisis provides a timely reminder of its ongoing contribution and future potential in creating a more sustainable, reliable, low carbon energy system.

Renewable Energy Cost Trends highlight IRENA data showing solar and wind undercut coal, as utility-scale projects drive lower levelized electricity costs worldwide, with the Middle East and UAE advancing mega solar parks.

Key Points

They track how solar and wind undercut new fossil fuels as utility-scale costs drop and investment accelerates.

✅ IRENA reports renewables cheapest for new installations

✅ Solar and wind LCOE fell sharply since 2010

✅ Middle East and UAE scale mega utility projects

Renewable energy is now the cheapest option for new electricity installation in most of the world, a report from the International Renewable Energy Agency (IRENA) on Tuesday said.

Renewable power projects have undercut traditional coal fuel plants, with solar and wind power costs in particular falling as record-breaking growth continues worldwide.

“Installing new renewables increasingly costs less than the cheapest fossil fuels. With or without the health and economic crisis, dirty coal plants were overdue to be consigned to the past, said Francesco La Camera, director-general of IRENA said in the report.

In 2019, renewables accounted for around 72 percent of all new capacity added worldwide, IRENA said, following a 2016 record year that highlighted the momentum, with lowering costs and technological improvements in solar and wind power helping this dynamic. For solar energy, IRENA notes that the cost for electricity from utility-scale plants fell by 82 percent in the decade between 2010 and 2019, as China's solar PV growth underscored in 2016.

“More than half of the renewable capacity added in 2019 achieved lower electricity costs than new coal, while new solar and wind projects are also undercutting the cheapest and least sustainable of existing coal-fired plants,” Camera added.

Costs for solar and wind power also fell year-on-year by 13 and 9 percent, respectively, with offshore wind costs showing steep declines as well. In 2019, more than half of all newly commissioned utility-scale renewable power plants provided electricity cheaper than the lowest cost of a new fossil fuel plant.

The Middle East

In mid-May, a report by UK-based law firm Ashurst suggested the Middle East is the second most popular region for renewable energy investment after North America, at a time when clean energy investment is outpacing fossil fuels.

The region is home to some of the largest renewable energy bets in the world, with Saudi wind expansion gathering pace. The UAE, for instance, is currently developing the Mohammed Bin Rashid Solar Park, the world’s largest concentrated solar power project in the world.

Around 26 percent of Middle East respondents in Ashurst’s survey said that they were presently investing in energy transition, marking the region as the most popular for current investment in renewables, while 11 percent added that they were considering investing.

In North America, the most popular region, 28 percent said that they were currently investing, with 11 percent stating they are considering investing.
