TVA energy plan pays off

U.S. Natural Gas Power Demand is surging for electricity generation amid summer heat, with ERCOT, Texas grid reserves tight, EIA reporting coal and nuclear retirements, renewables intermittency, and pipeline expansions supporting combined-cycle capacity and prices.

Key Points

It is rising use of natural gas for power, driven by summer heat, plant retirements, and new combined-cycle capacity.

✅ ERCOT reserve margin 9%, below 14% target in Texas

✅ Gas share of U.S. power near 40-43% this summer

✅ Coal and nuclear retirements shift capacity to combined cycle

As the hot months linger, it will be natural gas that is leaned on most to supply the electricity that we need to run our air conditioning loads on the grid and keep us cool.

And this is surely a great and important thing: "Heat causes most weather-related deaths, National Weather Service says."

Generally, U.S. gas demand for power in summer is 35-40% higher than what it was five years ago, with so much more coming (see Figure).

The good news is regions across the country are expected to have plenty of reserves to keep up with power demand.

The only exception is ERCOT, covering 90% of the electric load in Texas, where a 9% reserve margin is expected, below the desired 14%.

Last summer, however, ERCOT’s reserve margin also was below the desired level, yet the grid operator maintained system reliability with no load curtailments.

Simply put, other states are very lucky that Texas has been able to maintain gas at 50% of its generation, despite being more than justified to drastically increase that.

At about 1,600 Bcf per year, the flatness of gas for power demand in Texas since 2000 has been truly remarkable, especially since Lone Star State production is up 50% since then.

Increasingly, other U.S. states (and even countries) are wanting to import huge amounts of gas from Texas, a state that yields over 25% of all U.S. output.

Yet if Texas justifiably ever wants to utilize more of its own gas, others would be significantly impacted.

At ~480 TWh per year, if Texas was a country, it would be 9th globally for power use, even ahead of Brazil, a fast growing economy with 212 million people, and France, a developed economy with 68 million people.

In the near-term, this explains why a sweltering prolonged heat wave in July in Texas, with a hot Houston summer setting new electricity records, is the critical factor that could push up still very low gas prices.

But for California, our second highest gas using state, above-average snowpack should provide a stronger hydropower for this summer season relative to 2018.

Combined, Texas and California consume about 25% of U.S. gas, with Texas' use double that of California.

Across the U.S., gas could supply a record 40-43% of U.S. electricity this summer even as the EIA expects solar and wind to be larger sources of generation across the mix

Our gas used for power has increased 35-40% over the past five years, and January power generation also jumped on the year, highlighting broad momentum.

Indeed, U.S. natural gas for electricity has continued to soar, even as overall electricity consumption has trended lower in some years, at nearly 10,700 Bcf last year, a 16% rise from 2017 and easily the highest ever.

Gas is expected to supply 37% of U.S. power this year, even as coal-fired generation saw a brief uptick in 2021 in EIA data, versus 27% just five years ago (see Figure).

Capacity wise, gas is sure to continue to surge its share 45% share of the U.S. power system.

"More than 60% of electric generating capacity installed in 2018 was fueled by natural gas."

We know that natural gas will continue to be the go-to power source: coal and nuclear plants are retiring, and while growing, wind and solar are too intermittent, geography limited, and transmission short to compensate like natural gas can.

"U.S. coal power capacity has fallen by a third since 2010," and last year "16 gigawatts (16,000 MW) of U.S. coal-fired power plants retired."

This year, some 2,000 MW of coal was retired in February alone, with 7,420 MW expected to be closed in 2019.

Ditto for nuclear.

Nuclear retirements this year include Pilgrim, Massachusetts’s only nuclear plant, and Three Mile Island in Pennsylvania.

This will take a combined ~1,600 MW of nuclear capacity offline.

Another 2,500 MW and 4,300 MW of nuclear are expected to be leaving the U.S. power system in 2020 and 2021, respectively.

As more nuclear plants close, EIA projects that net electricity generation from U.S. nuclear power reactors will fall by 17% by 2025.

From 2019-2025 alone, EIA expects U.S. coal capacity to plummet nearly 25% to 176,000 MW, with nuclear falling 15% to 83,000 MW.

In contrast, new combined cycle gas plants will grow capacity almost 30% to around 310,000 MW.

Lower and lower projected commodity prices for gas encourage this immense gas build-out, not to mention non-stop increases in efficiency for gas-based units.

Remember that these are official U.S. Department of Energy estimates, not coming from the industry itself.

In other words, our Department of Energy concludes that gas is the future.

Our hotter and hotter summers are therefore more and more becoming: "summers for natural gas"

Ultimately, this shows why the anti-pipeline movement is so dangerous.

"Affordable Energy Coalition Highlights Ripple Effect of Natural Gas Moratorium."

In April, President Trump signed two executive orders to promote energy infrastructure by directing federal agencies to remove bottlenecks for gas transport into the Northeast in particular, where New England oil-fired generation has spiked, and to streamline federal reviews of border-crossing pipelines and other infrastructure.

Builders, however, are not relying on outside help: all they know is that more U.S. gas demand is a constant, so more infrastructure is mandatory.

They are moving forward diligently: for example, there are now some 27 pipelines worth $33 billion already in the works in Appalachia.

National Grid Cybersecurity Component Removal signals NCSC and GCHQ oversight of critical infrastructure, replacing NR Electric and Nari Technology grid control systems to mitigate supply chain risk, cyber threats, and blackout risk.

Key Points

A UK move to remove China-linked grid components after NCSC/GCHQ advice, reducing cyber and blackout risks.

✅ NCSC advice to remove NR Electric components

✅ GCHQ-linked review flags critical infrastructure risks

✅ Aims to cut blackout risk and supply chain exposure

Britain's National Grid has started removing components supplied by a unit of China-backed Nari Technology's from the electricity transmission network over cybersecurity fears, reflecting a wider push on protecting the power grid across critical sectors.

The decision came in April after the utility sought advice from the National Cyber Security Center (NCSC), a branch of the nation's signals intelligence agency, Government Communications Headquarters (GCHQ), amid campaigns like the Dragonfly campaign documented by Symantec, the newspaper quoted a Whitehall official as saying.

National Grid declined to comment citing "confidential contractual matters." "We take the security of our infrastructure very seriously and have effective controls in place to protect our employees and critical assets, while preparing for an independent operator transition in Great Britain, to ensure we can continue to reliably, safely and securely transmit electricity," it said in a statement.

The report said an employee at the Nari subsidiary, NR Electric Company-U.K., had said the company no longer had access to sites where the components were installed, at a time when utilities worldwide have faced control-room intrusions by state-linked hackers, and that National Grid did not disclose a reason for terminating the contracts.

It quoted another person it did not name as saying the decision was based on NR Electric Company-U.K.'s components that help control and balance the grid, respond to work-from-home demand shifts, and minimize the risk of blackouts.

It was unclear whether the components remained in the electricity transmission network, the report said, amid reports of U.S. power plant breaches that have heightened vigilance.

NR Electric Company-U.K., GCHQ and the Chinese Embassy in London did not immediately respond to requests for comment outside of business hours.

Britain's Department for Energy Security and Net Zero said that it did not comment on the individual business decisions taken by private organizations. "As a government department we work closely with the private sector to safeguard our national security, and to support efforts to fast-track grid connections across the network," it said in a statement.

Vietnam Offshore Wind Regulations expand coastal zones to six nautical miles, remove water depth limits, streamline permits, and boost investment, grid integration, and renewable energy capacity across deeper offshore wind resource areas.

Key Points

Policies extend sites to six nautical miles, scrap depth limits, and speed permits to scale offshore wind.

✅ Extends offshore zones to six nautical miles from shore

✅ Removes water depth limits to access stronger winds

✅ Streamlines permits, aiding grid integration and finance

Vietnam has recently redefined its regulations for offshore wind power projects, marking a significant development in the country's renewable energy ambitions. This strategic shift aims to streamline regulatory processes, enhance project feasibility, and accelerate the deployment of offshore wind energy in Vietnam's coastal regions, amid a trillion-dollar offshore wind market globally.

Regulatory Changes

The Vietnamese government has adjusted offshore wind power regulations by extending the allowable distance from shore for wind farms to six nautical miles (approximately 11 kilometers), a move that aligns with evolving global practices such as Canada's offshore wind plan announced recently by regulators. This expansion from previous limits aims to unlock new areas for development and maximize the utilization of Vietnam's vast offshore wind potential.

Scrapping Depth Restrictions

In addition to extending offshore boundaries, Vietnam has removed restrictions on water depth for offshore wind projects. This revision allows developers to explore deeper waters, where wind resources may be more abundant, thereby diversifying project opportunities and optimizing energy generation capacity.

Strategic Implications

The redefined regulations are expected to stimulate investment in Vietnam's renewable energy sector, attracting domestic and international stakeholders keen on capitalizing on the country's favorable wind resources, with World Bank support for wind underscoring the growing pipeline in developing markets. The move aligns with Vietnam's broader energy diversification goals and commitment to reducing reliance on fossil fuels.

Economic Opportunities

The expansion of offshore wind development zones creates economic opportunities across the value chain, from project planning and construction to operation and maintenance. The influx of investments is anticipated to spur job creation, technology transfer, and infrastructure development in coastal communities, as industry groups like Marine Renewables Canada shift toward offshore wind specialization.

Environmental and Energy Security Benefits

Harnessing offshore wind power contributes to Vietnam's efforts to mitigate greenhouse gas emissions and combat climate change. By integrating renewable energy sources into its energy mix, Vietnam enhances energy security, as seen in the UK offshore wind expansion, reduces dependency on imported fuels, and promotes sustainable economic growth.

Challenges and Considerations

Despite the promising outlook, offshore wind projects face challenges such as technical complexities, environmental impact assessments, and grid integration, as well as exposure to policy risk exemplified by U.S. opposition to offshore wind debates.

Future Outlook

Looking ahead, Vietnam's redefined offshore wind regulations position the country as a key player in the global renewable energy transition, a trend reinforced by progress in offshore wind in Europe elsewhere. Continued policy support, investment facilitation, and technological innovation will be critical in unlocking the full potential of offshore wind power and achieving Vietnam's renewable energy targets.

Conclusion

Vietnam's revision of offshore wind power regulations reflects a proactive approach to advancing renewable energy development and fostering a conducive investment environment. By expanding development zones and eliminating depth restrictions, Vietnam sets the stage for accelerated growth in offshore wind capacity, contributing to both economic prosperity and environmental stewardship. As stakeholders seize opportunities in this evolving landscape, collaboration and innovation will drive Vietnam towards a sustainable energy future powered by offshore wind.

Iraq Electricity Crisis intensifies as summer heat drives demand; households face power outages, reliance on private generators, distorted tariffs, and strained grid capacity despite government reforms, Siemens upgrades, and IEA warnings.

Key Points

A supply-demand gap causing outages, generator reliance, and grid inefficiencies across Iraq, worsened by summer peaks.

✅ Siemens deal to upgrade generation and grid

✅ Progressive tariffs to curb demand and waste

✅ Private generators fill gaps but raise costs

At a demonstration in June 2018, protesters in Basra loaded a black box resembling a coffin with the inscription “Electricity” onto the roof of a car. This was one demonstration of how much of a political issue electricity is in Iraq.

With what is likely to be another hot summer ahead, there is increasing pressure on the Baghdad government to improve access to electricity and water.

Many Iraqis blame the government for not providing adequate services despite the country’s oil wealth. Protests in southern Iraq last year turned violent, with demonstrators attacking governmental and political parties’ buildings; in neighboring Iran, blackouts also sparked protests over outages.

“It is very hard” to deal with the electricity issues, said Iraqi journalist Methaq al-Fayyadh, adding that the lack of reliable electricity was not a new problem and affects most parts of the country.

Dozens of people protested June 1 in Karbala against prices for new generators and demanded an improvement to the electricity situation.

In anticipation of high temperatures during Eid al-Fitr, the Electricity Ministry called on governorates to adhere to allocated quotas and told the public to ration electricity.

“Outages remain a daily occurrence for most households because increasing generating capacity has been outrun by increasing demand for electricity, as surging demand worldwide demonstrates,” noted the International Energy Agency (IAE) in April.

This is particularly the case, the authors said, as the hot summer months, when temperatures can top 50 degrees Celsius, drive up the use of air conditioning.

The Iraqi government has made improving the electricity supply one of its priorities, including nuclear power plans under consideration. The Electricity Ministry, headed by Luay al-Khatteeb, announced in May that national electricity production had reached 17 gigawatts.

Khatteeb presented comparative electricity data for May from 2018 and 2019, indicating production increases on every day of the month. IEA data indicate that available electricity supply has increased over the past five years and the gap between supply and demand has widened.

The government signed an agreement with German company Siemens this year to upgrade Iraq’s electricity grid, and in parallel deals with Iran to rehabilitate and develop the grid were finalized, according to Iranian officials. The agreement “includes the addition of new and highly efficient power generation capacity, rehabilitation and upgrade of existing plants and the expansion of transmission and distribution networks,” Siemens said.

The Iraqi prime minister’s office said the 4-year plan would be worth $15.7 billion. The first phase includes the installation of 13 transformer stations, cooling systems for power stations and building a 500-megawatt, gas-fired power plant south of Baghdad.

In an interview with Al-Monitor, Khatteeb said radical changes would happen in 2020, stating that the current situation was not “ideal” but “better” because of steps taken to create more energy, amid discussions on energy cooperation with Iran that could shape implementation.

Robert Tollast, of the Iraq Energy Institute, said the economics of the electricity system is distorted. Subsidies ensured that electricity provided by the national grid is almost free, he said. However, while the subsidies were designed to help the poor, the tariff system disadvantages them and does not create incentives to consume electricity more efficiently, he said.

A large part of families’ electricity expenditures goes to operators of privately owned generators, which run on fuel. These neighbourhood generators are used to close gaps in the electricity supply but are expensive, and regional fuel arrangements such as ENOC’s swap of Iraqi fuel have highlighted supply constraints. Generator operators have sometimes worked with armed groups to prevent upgrades to the grid that could hurt their business.

Until 1990, the Iraq electricity sector was considered among the best in the region. That legacy was destroyed by successive wars and international sanctions. With Iraq’s population growing at a rate of 1 million per year, peak demand is projected to double by 2030 if left unchecked, the IEA estimated.

Tollast said efforts to improve the distribution system and increase capacity are key but it is important “to tackle the problem from the demand side.” This entails implementing a progressive tariff scheme so users pay more if they consume more, he said. There is a “tremendous use of energy per capita in Iraq,” Tollast said.

In the current tariff structure, consumers pay a fixed price if they use more than 4,000-kilowatt hours per year, a relatively low amount, meaning the price per unit drops the more one consumes.

Any change to the tariff system must be accompanied by a “political campaign” to explain the changes, said Tollast, adding that more investment in the electricity sector and a “change in culture” of using electricity was needed. “The current system is unsustainable, even with high oil prices,” he said.

Fayyadh said people don’t expect the government will be able to fix the electricity issue before summer, having failed to do so in the past.

Tollast struck a more optimistic tone, saying it was unlikely that Iran, which supplies about 40% of Iraq’s power, would cut its export of electricity to Iraq this year as it did in 2018. He added that the water situation was better than last year when the country experienced drought. Iraq has also been processing more flare gas, which can be used to generate electricity.

“There is an expectation that this year might not be as bad as last year,” he concluded.

Pickering Nuclear False Alert Investigation probes Ontario's emergency alert system after a provincewide cellphone, radio, and TV warning, assessing human error, Pelmorex safeguards, Emergency Management Ontario oversight, and communication delays.

Key Points

An Ontario probe into the erroneous Pickering nuclear alert, focusing on human error, system safeguards, and oversight.

✅ Human error during routine testing suspected

✅ Pelmorex safeguards and EMO protocols under review

✅ Two-hour all-clear delay prompts communication fixes

An investigation into a mistaken Pickering alert warning of an incident at the Pickering Nuclear Generating Station will be completed fairly quickly, Ontario's solicitor general said.

Sylvia Jones tapped the chief of Emergency Management Ontario to investigate how the alert warning of an unspecified problem at the facility was sent in error to cellphones, radios and TVs across the province at about 7:30 a.m. Sunday.

"It's very important for me, for the people of Ontario, to know exactly what happened on Sunday morning," said Jones. "Having said that, I do not anticipate this is going to be a long, drawn-out investigation. I want to know what happened and equally important, I want some recommendations on insurances and changes we can make to the system to make sure it doesn't happen again."

Initial observations suggest human error was responsible for the alert that was sent out during routine tests of the emergency alert, Jones said.

"This has never happened in the history of the tests that they do every day, twice a day, but I do want to know exactly all of the issues related to it, whether it was one human error or whether it was a series of things."

Martin Belanger, the director of public alerting for Pelmorex, a company that operates the alert system, said there are a number of safeguards built in, including having two separate platforms for training and live alerts.

"The software has some steps and some features built in to minimize that risk and to make sure that users will be able to know whether or not they're sending an alert through the...training platform or whether they're accessing the live system in the case of a real emergency," he said.

Only authorized users have access to the system and the province manages that, Belanger said. Once in the live system, features make the user aware of which platform they are using, with various prompts and messages requiring the user's confirmation. There is a final step that also requires the user to confirm their intent of issuing an alert to cellphones, radio and TVs, Belanger said.

On Sunday, a follow-up alert was sent to cellphones nearly two hours after the original notification, and similar grid alerts in Alberta underscore timing and public expectations.

NDP energy critic Peter Tabuns is critical of that delay, noting that ongoing utility scam warnings can further erode public trust.

"That's a long time for people to be waiting to find out what's really going on," he said. "If people lose confidence in this system, the ability to use it when there is a real emergency will be impaired. That's dangerous."

Treasury Board President Peter Bethlenfalvy, who represents the riding of Pickering-Uxbridge, said getting that alert Sunday morning was "a shock to the system," and he too wants the investigation to address the reason for the all-clear delay.

"We all have a lot of questions," he said. "I think the public has every right to know exactly what went on and we feel exactly the same way."

People in the community know the facility is safe, Bethlenfalvy said.

"We have some of the safest nuclear assets in the world -- the safest -- at 60 per cent of Ontario's electricity," he said.

A poll released Monday found that 82 per cent of Canadians are concerned about spills from nuclear reactors contaminating drinking water and 77 per cent are concerned about neighbourhood safety and security risks for those living close to nuclear plants. Oraclepoll Research surveyed 2,094 people across the country on behalf of Friends of the Earth between Jan. 2 and 12, the day of the false alert. The have a margin of error of plus or minus 2.1 per cent, 19 times out of 20.

The wording of Sunday's alert caused much initial confusion, and events like a power outage in London show how morning disruptions can amplify concern, warning residents within 10 kilometres of the plant of "an incident," though there was no "abnormal" release of radioactivity and residents didn't need to take protective steps, but emergency crews were responding.

In the event of a real emergency, the wording would be different, Jones said.

"There are a number of different alerts that are already prepared and are ready to go," she said. "We have the ability to localize it to the communities that are impacted, but because this was a test, it went provincewide."

Jones said she expects the results of the probe to be made public.

The Pickering nuclear plant has been operating since 1971, and had been scheduled to be decommissioned this year, but the former Liberal government -- and the current Progressive Conservative government -- committed to keeping it open until 2024. Decommissioning is now set to start in 2028.

It operates six CANDU reactors, generates 14 per cent of Ontario's electricity and is responsible for 4,500 jobs across the region, according to OPG, and OPG's credit rating remains stable.

During the COVID-19 pandemic, Hydro One employees supported the Province of Ontario in the fight against COVID-19.

The Green party is calling on the province to use this opportunity to review its nuclear emergency response plan, including pandemic staffing contingencies, last updated in 2017 and subject to review every five years.

Toronto Mayor John Tory praised Ontario for swiftly launching an investigation, but said communication between city and provincial officials wasn't what it should have been under the circumstances.

"It was a poor showing and I think everybody involved knows that," he said. "We've got to make sure it's not repeated."

Puerto Rico Tesla Solar Power enables resilient microgrids using batteries, renewable energy, and energy storage to rebuild the hurricane-damaged grid, reduce fossil fuels, cut costs, and accelerate recovery with scalable solar-plus-storage solutions.

Key Points

A solar-plus-storage plan using Tesla microgrids and batteries to restore Puerto Rico's cleaner, resilient power.

✅ Microgrids cut diesel reliance and harden critical facilities.

✅ Batteries stabilize the grid and shave peak demand costs.

✅ Scalable solar enables faster, modular disaster recovery.

Puerto Rico’s governor Ricardo Rossello has said that he will speak to Elon Musk after the Tesla inventor said his innovative solar and battery systems could be used to restore electricity on the island.

Mr Musk was mentioned in a tweet, referencing an article discussing ways to restore Puerto Rico’s power grid, which was knocked out by Hurricane Maria on September 20.

Restoring the ageing and already-weakened network has proved slow: as of Friday 90 per cent of the island remained without power. The island’s electricity company was declared bankrupt in July.

Mr Musk was asked: “Could @ElonMusk go in and rebuild #PuertoRico’s electricity system with independent solar & battery systems?”

The South African entrepreneur replied: “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too.

“Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR.”

His suggestion was seized upon by Mr Rossello, who then tweeted: “@ElonMusk Let's talk. Do you want to show the world the power and scalability of your #TeslaTechnologies?

“PR could be that flagship project.”

Mr Musk replied that he was happy to talk.

Restoring power to the battered island is a priority for the government, and improving grid resilience remains critical, with hospitals still running on generators and the 3.5 million people struggling with a lack of refrigeration or air conditioning.

Radios broadcast messages advising people how to keep their insulin cool, and doctors are concerned about people not being able to access dialysis.

And, with its power grid wiped out, the Caribbean island could totally rethink the way it meets its energy needs, drawing on examples like a resilient school microgrid built locally. 

“This is an opportunity to completely transform the way electricity is generated in Puerto Rico and the federal government should support this,” said Judith Enck, the former administrator for the region with the environmental protection agency.

“They need a clean energy renewables plan and not spending hurricane money propping up the old fossil fuel infrastructure.”

Forty-seven per cent of Puerto Rico’s power needs were met by burning oil last year - a very expensive and outdated method of electricity generation. For the US as a whole, petroleum accounted for just 0.3 per cent of all electricity generated in 2016 even as the grid isn’t yet running on 100% renewable energy nationwide.

The majority of the rest of Puerto Rico’s energy came courtesy of coal and natural gas, with renewables, which later faced pandemic-related setbacks, accounting for only two per cent of electricity generation.

“In that time of extreme petroleum prices, the utility was borrowing money and buying oil in order to keep those plants operating,” said Luis Martinez, a lawyer at natural resources defense council and former special aide to the president of Puerto Rico’s environmental quality board.

“That precipitated the bankruptcy that followed. It was in pretty poor shape before the storm. Once the storm got there, it finished the job.”

But Mr Martinez told the website Earther that it might be difficult to secure the financing for rebuilding Puerto Rico with renewables from FEMA (Federal Emergency Management Agency) funds.

“A lot of distribution lines were on wood poles,” he said.

“Concrete would make them more resistant to winds, but that would potentially not be authorized under the use of FEMA funds.

"We’re looking into if some of those requirements can be waived so rebuilding can be more resilient.”
