Areva's troublesome EPR reactor project in Finland received a clean bill of health after welding work overseen by Bouygues, the French nuclear group's subcontractor, was called into question.

Petteri Tiippana, assistant director of STUK, the Finnish nuclear safety authority, said that a government-commissioned inquiry into quality and safety allegations made by the environmental lobby group Greenpeace had found no evidence of transgressions.

On the 35 load-bearing welded joints inspected by STUK, "the welding procedures, the qualification of the welders, the welds themselves are well done", he said.

On the thousands of non-load bearing joints which are not inspected by STUK, "the welds were made by qualified welders and systematic inspections were made", he went on to point out.

Mr Tiippana also refuted allegations made in a television documentary broadcast that Bouygues employees had been banned from discussing safety concerns.

The inquiry found no such rules and STUK inspectors had not had any problems discussing safety with them. However, workers had to seek approval before talking to anyone off-site, such as journalists.

STUK said it had been convinced by the Bouygues project manager "that all employees are obliged to report... any safety-related deviances.

"Deviances are documented and fixed according to the quality system."

STUK said it would check this documentation.

Bouygues said that the issue was now closed and it would not comment further.

Nonetheless, the controversy was taken seriously by the French construction group, which this summer was criticized along with power utility EDF for organisation of work on concrete reinforcement in a EPR reactor which is being built in Normandy.

Areva said it was delighted with STUK's public statement as "delivering a safe EPR reactor is an absolute priority for us".

Finland's Olkiluoto3 EPR reactor is being built by a consortium led by Areva.

It is the world's first so-called third-generation nuclear reactor, an Areva design and the group's first turnkey project, has been fraught with problems and is currently running two years late and at least €1bn ($1.47bn) over budget.

The Power Sector’s Most Crucial COVID-19 Mitigation Strategies

ESCC COVID-19 Resource Guide outlines control center continuity, sequestration, social distancing, remote operations, testing priorities, mutual assistance, supply chain risk, and PPE protocols to sustain grid reliability and plant operations during the COVID-19 pandemic.

 

Key Points

An industry guide to COVID-19 mitigation for the power sector covering control centers, testing, PPE, and mutual aid.

✅ Control center continuity: segregation, remote ops, reserve shifts

✅ Sequestration triggers, testing priorities, and PPE protocols

✅ Mutual assistance, supply chain risk, and workforce planning

 

The latest version of the Electricity Subsector Coordinating Council’s (ESCC’s) resource guide to assess and mitigate COVID-19 suggests the U.S. power sector continues to grapple with key concerns involving control center continuity, power plant continuity, access to restricted and quarantined areas, mutual assistance, and supply chain challenges, alongside urban demand shifts seen in Ottawa’s electricity demand during closures.

In its fifth and sixth versions of the “ESCC Resource Guide—Assessing and Mitigating the Novel Coronavirus (COVID-19),” released on April 16 and April 20, respectively, the ESCC expanded its guidance as it relates to social distancing and sequestration within tight power sector environments like control centers, crucial mitigation strategies that are designed to avoid attrition of essential workers.

The CEO-led power sector group that serves as a liaison with the federal government during emergencies introduced the guide on March 23, and it provides periodic updates  sourced from “tiger teams,” which are made up of representatives from investor-owned electric companies, public power utilities, electric cooperatives, independent power producers (IPPs), and other stakeholders. Collating regulatory updates and emerging resources, it serves as a general shareable blueprint for generators,  transmission and distribution (T&D) facilities, reliability coordinators, and balancing authorities across the nation on issues the sector is facing as the COVID-19 pandemic endures.

Controlling Spread at Control Centers
While control centers are typically well-isolated, physically secure, and may be conducive to on-site sequestration, the guide is emphatic that staff at these facilities are typically limited and they need long lead times to be trained to properly use the information technology (IT) and operational technology (OT) tools to keep control centers functioning and maintain grid visibility. Control room operators generally include: reliability engineers, dispatchers, area controllers, and their shift supervisors. Staff that directly support these function, also considered critical, consist of employees who maintain and secure the functionality of the IT and OT tools used by the control room operators.

In its latest update, the ESCC notes that many entities took “proactive steps to isolate their control center facilities from external visitors and non-essential employees early in the pandemic, leveraging the presence of back-up control centers, self-quarantining of employees, and multiple shifts to maximize social distancing.” To ensure all levels of logistical and operational challenges posed by the pandemic are addressed, it envisions several scenarios ranging from mild contagion—where a single operator is affected at one of two control center sites to the compromise of both sites.

Previous versions of the guide have set out universal mitigation strategies—such as clear symptom reporting, cleaning, and travel guidance. To ensure continuity even in the most dire of circumstances, for example, it recommends segregating shifts, and even sequestering a “complete healthy shift” as a “reserve” for times when minimum staffing levels cannot be met. It also encourages companies to develop a backup staff of retirees, supervisors, managers, and engineers that could backfill staffing needs.

Meanwhile, though social distancing has always been a universal mitigation strategy, the ESCC last week detailed what social distancing at a control room could look like. It says, for example, that entities should consider if personnel can do their jobs in spaces adjacent to the existing control room; moving workstations to allow at least six feet of space between employees; or designating workstations for individual operators. The guide also suggests remote operations outside of a single control room as an option, and some markets are exploring virtual power plant models in the UK to support flexibility, though it underscores that not all control center operations can be performed remotely, and remote operations increase the potential for security vulnerabilities. “The NERC [North American Electric Reliability Corp.] Reliability Standards address requirements for BES [bulk electric system] control centers and security controls for remote access of systems, applications, or data,” the resource guide notes.

Sequestration—Highly Effective but Difficult
Significantly, the new update also clarifies circumstances that could “trigger” sequestration—or keeping mission-essential workers at facilities. Sequestration, it notes, “is likely to be the most effective means of reducing risk to critical control center employees during a pandemic, but it is also the most resource- and cost-intensive option to implement.”

It is unclear exactly how many power sector workers are currently being sequestered at facilities. According to the  American Public Power Association (APPA), as of last week, the New York Power Authority was sequestering 82 power plant control room and transmission control operator, amid New York City’s shifting electric rhythms during COVID-19; the Sacramento Municipal Utility District (SMUD) in California had begun sequestering critical employees; and the Electric & Gas Utility at the City of Tallahassee had 44 workers being rotated in and out of sequestration. Another 37 workers from the New York ISO were already being sequestered or housed onsite as of April 9. PJM began sequestering a team of operators on April 11, and National Grid was sequestering 200 employees as of April 12. 

Decisions to trigger sequestration at T&D and other grid monitoring facilities are typically driven by entities’ risk assessment, ESCC noted. Considerations may involve: 

The number of people showing symptoms or testing positive as a percentage of the population in a county or municipality where the control center is sited. One organization, for example, is considering a lower threshold of 10% community infection as a trigger of “officer-level decision” to determine whether to sequester. A higher threshold of 20% “mandates a move to sequestration,” ESCC said.
The number of essential workers showing symptoms or having tested positive. “Acceptable risk should be based on the minimum staffing requirements of the control center and should include the availability of a reserve shift for critical position backfills. For example, shift supervisors are commonly certified in all positions in the control center, and the unavailability of more than one-third of a single organization’s shift supervisors could compromise operations,” it said.
The rate of infection spread across a geographic region. In the April 20 version, the guide removes specific mention that cases are doubling “every 3–5 days or more frequently in some areas.” It now says:  “Considering the rapid spread of COVID-19, special care should be taken to identify the point at which control center personnel are more likely than not to come into contact with an infected individual during their off-shift hours.”
Generator Sequestration Measures Vary
Generators, meanwhile, have taken different approaches to sequester generation operators. Some have reacted to statewide outbreaks, others to low reserves, and others still, as with one IPP, to control exposure to smaller staffs, which cannot afford attrition. The IPP, for example, decided sequestration was necessary because it “did not want to wait for confirmed cases in the workforce.” That company sequestered all its control room operators, outside operators, and instrumentation and control technicians.

The ESCC resource guide says workers are being sequestered in several ways. On-site, these could range from housing workers in two separate areas, for example, or in trailers brought in. Off-site, workers may be housed in hotel rooms, which the guide notes, “are plentiful.”

Location makes a difference, it said: “Onsite requires more logistical co-ordination for accommodations, food, room sanitization, linens, and entertainment.”  To accommodate sequestered workers, generators have to consider off-site food and laundry services (left at gates for pick-up)—and even extending Wi-Fi for personal use. Generators are learning from each other about all aspects of sequestration—including how to pay sequestered workers. It suggests sequestered workers should receive pay for all hours inside the plant, including straight time for regularly scheduled hours and time-and-a-half for all other hours. To maintain non-sequestered employees, who are following stay-at-home protocols, pay should remain regularly scheduled, it says.

Testing Remains a Formidable Hurdle
Though decisions to sequester differ among different power entities, they appear commonly complicated by one prominent issue: a dearth of testing.

At the center of a scuffle between the federal and state governments of late, the number of tests has not kept pace with the severity of the pandemic, and while President Trump has for some weeks claimed that “Testing is a local thing,” state officials, business leaders—including from the power sector—and public health experts say that it is far short of the several hundred thousands or perhaps even millions of daily tests it might take to safely restart the economy, even as calls to keep electricity options open grow among policymakers, a three-phase approach for which the Trump administration rolled out this week. While the White House said the approach is “based on the advice of public health experts, the suggestions do not indicate a specific timeframe. Some hard-hit states have committed to keeping current restrictions in place. New York on April 16 said it would maintain a shutdown order through May 15, while California published its own guidelines and states in the Northeast, Midwest, and West Coast entered regional pacts that may involve interstate coordination on COVID-19–related policy going forward.

On Sunday, responding to a call by governors across the political spectrum that insisted the federal government should step up efforts to help states obtain vital supplies for tests, Trump said the federal government will be “using” and “preparing to use” the Defense Production Act to increase swab production.

For the power entities that are part of the ESCC, widespread testing underlies many mitigation strategies. The group’s generation owners and operating companies, which include members from the full power spectrum, have said testing is central to “successful mitigation of risk to control center continuity.”

In the updated guide, the entities recommend requesting that governmental authorities—it is unclear whether the focus should be on the federal or state governments—“direct medical facilities to prioritize testing for asymptomatic generation control room operators, operator technicians, instrument and control technicians, and the operations supervisor (treat comparable to first responders) in advance of sequestered, extended-duration shifts; and obtain state regulatory approval for corporate health services organizations to administer testing for coronavirus to essential employees, if applicable.”

The second priority, as crucial, involves asking the government to direct medical facilities to prioritize testing for control room operators before they are sequestered or go into extended-duration shifts.

Generators also want local, regional, state, and federal governments to ensure operators of generating facilities are allowed to move freely if “populace-wide quarantine/curfew or other travel restrictions” are enacted. Meanwhile,  they have also asked federal agencies and state permitting agencies to allow for non-compliance operations of generating facilities in case enough workers are not available.

Lower on its list, but still “medium priority,” is that the government should obtain authority for priority supply of sanitizing supplies and personal protective equipment (PPE) for generating facilities. They are also asking states to allow power plant employees (as opposed to crucially redirected medical personnel) to administer health questionnaires and temperature checks without Americans with Disabilities Act or other legal constraints. Newly highlighted in the update, meanwhile, is an emphasis on enough fire retardant (FR) vests and hoods and PPE, including masks and face coverings, so technicians don’t have to share them.

The worst-case scenario envisioned for generators involves a 40% workforce attrition, a nine-month pandemic, and no mutual assistance. As the update suggests, along with universal mitigation strategies, some power companies are eliminating non-essential work that would require close contact, altering assignments so work tasks are done by paired teams that do not rotate, and ensuring workers wear masks. The resource guide includes case studies and lessons learned so far, and all suggest pandemic planning was crucial to response. 

Gearing Up for Mutual Assistance—Even for Generation—During COVID-19
Meanwhile, though the guide recognizes that protecting employees is a key priority for many entities, it also lauds the crucial role mutual assistance plays in the sector’s collective response to the pandemic, even as coal and nuclear plant closures test just transition planning across regions. Mutual assistance is a long-standing power sector practice in the U.S. Last week, for example, as severe weather impacted the southern and eastern portions of the U.S., causing power outages for 1.3 million customers at the peak, the sector demonstrated the “versatility of mutual assistance processes,” bringing in additional workers and equipment from nearby utilities and contractors to assist with assessment and repair. “Crews utilized PPE and social distancing per the CDC [Centers for Disease Control and Prevention] and OSHA [Occupational Safety and Health Administration] guidelines to perform their restoration duties,” the Energy Department told POWER.

But as the ESCC’s guide points out, mutual assistance has traditionally been deployed to help restore electric service to customers, typically focused on T&D infrastructure. The COVID-19 pandemic, uniquely, “has motivated generation entities to consider the use of mutual assistance for generation plant operation” it notes. As with the model it proposes to ensure continuity of control centers, mutual aid poses key challenges, such as for task variance, knowledge of operational practice, system customization, and legal indemnification.

Among guidelines ESCC proposes for generators are to use existing employee work stoppage plans as a resource in planning for the use of personnel not currently assigned to plant operation. It urges, for example, that generators keep a list of workers with skills who can be called from corporate/tech support (such as former operators or plant engineers/managers), or retirees and other individuals who could be called upon to help operate the control room first. ESCC also recommends considering the use of third-party contractor operations to supplement plant operations.

Key to these efforts is to “Create a thorough list of experience and qualifications needed to operate a particular unit. Important details include fuel type, OEM [original equipment manufacturer] technology, DCS [distributed control system] type, environmental controls, certifications, etc,” it says. “Consider proactively sharing this information internally within your company first and then with neighboring companies”—and that includes sufficient detail from manufacturers (such as Emerson Ovation, GE Mark VI, ABB, Honeywell)—“without exposing proprietary information.” One way to control this information is to develop a mutual assistance agreement with “strategic” companies within the region or system, it says.

Of specific interest is that the ESCC also recommends that generators consider “leaving units in extended or planned maintenance outage in that state as long as possible.” That’s because, “Operators at these offline sites could be considered available for a site responding to pandemic challenges,” it says.

However, these guidelines differ by resource. Nuclear generators, for example, already have robust emergency plans that include minimum staffing requirements, and owing to regulations, mutual aid is managed by each license holder, it says. However, to provide possible relief for attrition at operating nuclear plants, the Nuclear Regulatory Commission (NRC) on March 28 outlined a streamlined process that could allow nuclear operators to obtain exemptions from work hour rules, while organizations also point to IAEA low-carbon electricity lessons for future planning.

Uncertainty of Supply Chain Endurance
As the guide stresses, operational continuity during the pandemic will require that all power entities maintain supply of inputs and physical equipment. To help entities plan ahead—by determining volumes needed and geographic location of suppliers—it lists the most important materials needed for power delivery and bulk chemicals. “Clearly, the extent and duration of this emergency will influence the importance of one supply chain component compared to another,” it says.

As Massachusetts Institute of Technology supply chain expert David Simchi-Levi noted on April 13, global supply chains have been heavily taxed by the pandemic, and manufacturing activities in the European Union and North America are still going offline. China is showing signs of slow recovery. Even in the best-case scenario, however—even if North America and Europe manage to control and reduce the pandemic—the supply chain will likely experience significant logistical capacity shortages, from transportation to warehousing. Owing to variability in timing, he suggested that companies plan to reconfigure supply chains and reposition inventory in case suppliers go out of business or face quarantine, while some industry groups urge investing in hydropower as part of resilient recovery strategies.

Also in short supply, according to ESCC, is industry-critical PPE. “While our sector recognizes that the priority is to ensure that PPE is available for workers in the healthcare sector and first responders, a reliable energy supply is required for healthcare and other sectors to deliver their critical services,” its resource guide notes. “The sector is not looking for PPE for the entire workforce. Rather, we are working to prioritize supplies for mission-essential workers – a subset of highly skilled energy workers who are unable to work remotely and who are mission-essential during this extraordinary time.”

Among critical industry PPE needs are nitrile gloves, shoe covers, Tyvek suits, goggles/glasses, hand sanitizer, dust masks, N95 respirators, antibacterial soap, and trashbags. While it provides a list of non-governmental PPE vendors and suppliers, the guide also provides several “creative” solutions. These include, for example, formulations for effective hand sanitizer; 3D printer face shield files; methods for decontaminating face piece respirators and other PPE; and instructions for homemade masks with pockets for high-efficiency particulate air (HEPA) filter inserts.

China's nuclear energy on steady development track, say experts

China Nuclear Power Expansion accelerates with reactor approvals, Hualong One and CAP1400 deployments, rising gigawatts, clean energy targets, carbon neutrality goals, and grid reliability benefits to meet coastal demand and reduce emissions.

 

Key Points

An accelerated reactor buildout to add clean capacity, curb emissions, and improve grid reliability nationwide.

✅ Approvals surge for Hualong One and CAP1400 third-gen reactors

✅ Capacity targets approach 100 GW installed by 2030

✅ Supports carbon neutrality, energy security, and lower costs

 

While China has failed to accomplish its 2020 nuclear target of 58 gigawatts under operation and 30 GW under construction, insiders are optimistic about prospects for the nonpolluting energy resource in China over the next five years as the country has stepped up nuclear approvals and construction since 2020.

China expects to record 49 operating nuclear facilities and capacity of more than 51 GW as of the end of 2020. Nuclear power currently makes up around 2.4 percent of the country's total installed energy capacity, said the China Nuclear Energy Association. There are 19 facilities that have received approval and are under construction, with capacity exceeding 20 GW, ranking top globally as nuclear project milestones worldwide continue, it said.

"With surging power demand from coastal regions, more domestic technology, including next-gen nuclear, will be adopted with installations likely nearing 100 GW by the end of 2030," said Wei Hanyang, a power market analyst at Bloomberg New Energy.

Following the Fukushima nuclear reactor disaster in 2011 in Japan, China has, like many countries including Japan, Germany and Switzerland, suspended nuclear power project approvals for a period, including construction of the pilot project of Shidaowan nuclear power plant in Shandong province that uses CAP1400 technology, based on third-generation Westinghouse AP1000 reactor technology.

As China promotes greener development and prioritizes safety and security of nuclear power plant construction, it has pledged to hit peak emissions before 2030 and achieve carbon neutrality by 2060, with electricity meeting 60% of energy use by 2060 according to Shell, the Shidaowan plant, originally scheduled to launch construction in 2014 and enter service in 2018, is expected to start fuel loading and begin operations this year.

Joseph Jacobelli, an independent energy analyst and executive vice-president for Asia business at Cenfura Ltd, a smart energy services company, said recent developments confirm China's ongoing commitment to further boost the country's nuclear sector.

"The nuclear plants can help meet China's goal of reducing greenhouse gas emissions as the country reduces coal power production and provide air pollution-free energy at a lower cost to consumers. China's need for clean energy means that nuclear power generation definitely has an important place in the long-term energy mix," Jacobelli said.

He added that Chinese companies' cost control capabilities and technological advancements, and operational performance improvements such as the AP1000 refueling outage record, are also likely to continue providing domestic companies with advantages, as the cost per kilowatt-hour is very important, especially as solar, wind and other clean energy solutions become even cheaper over the next few years.

China approved two nuclear projects in 2020- Hainan Changjiang nuclear power plant unit 2 and Zhejiang San'ao nuclear power plant unit 1. This is after the country launched three new nuclear power plants in 2019 in the provinces of Shandong, Fujian and Guangdong, which marked the end of a moratorium on new projects.

The Zhejiang San'ao nuclear power plant saw concrete poured for unit 1 on Dec 31, according to its operator China General Nuclear. It will be the first of six Hualong One pressurized water reactors to be built at the site as well as the first Chinese nuclear power plant project to involve private capital.

Jointly invested, constructed and operated by CGN, Zheneng Electric Power, Wenzhou Nuclear Energy Development, Cangnan County Haixi Construction Development and Geely Maijie Investment, the project creates a new model of mixed ownership of nuclear power enterprises, said CGN.

The world's first Hualong One reactor at unit 5 of China National Nuclear Corp's Fuqing nuclear plant in Fujian province was connected to the grid in November. With the start of work on San'ao unit 1, China now has further seven Hualong One units under construction, including Fuqing 6, which is scheduled to go online this year.

CNNC is also constructing one unit at Taipingling in Guangdong and two at Zhangzhou in Fujian province. CGN is building two at its Fangchenggang site in Guangxi Zhuang autonomous region. In addition, two Hualong One units are under construction at Karachi in Pakistan, while CGN proposes to use a UK version of the Hualong One at Bradwell in the United Kingdom, aligning with the country's green industrial revolution strategy.

5 ways Texas can improve electricity reliability and save our economy

Texas Power Grid Reliability faces ERCOT blackouts and winter storm risks; solutions span weatherization, natural gas coordination, PUC-ERCOT reform, capacity market signals, demand response, grid batteries, and geothermal to maintain resilient electricity supply.

 

Key Points

Texas Power Grid Reliability is ERCOT's ability to keep electricity flowing during extreme weather and demand spikes.

✅ Weatherize power plants and gas supply to prevent freeze-offs

✅ Merge PUC and Railroad Commission for end-to-end oversight

✅ Pay for firm capacity, demand response, and grid storage

 

The blackouts in February shined a light on the fragile infrastructure that supports modern life. More and more, every task in life requires electricity, and no one is in charge of making sure Texans have enough.

Of the 4.5 million Texans who lost power last winter, many of them also lost heat and at least 100 froze to death. Wi-Fi stopped working and phones soon lost their charges, making it harder for people to get help, find someplace warm to go or to check in on loved ones.

In some places pipes froze, and people couldn’t get water to drink or flush after power and water failures disrupted systems, and low water pressure left some health care facilities unable to properly care for patients. Many folks looking for gasoline were out of luck; pumps run on electricity.

But rather than scouting for ways to use less electricity, we keep plugging in more things. Automatic faucets and toilets, security systems and locks. Now we want to plug in our cars, so that if the grid goes down, we have to hope our Teslas have enough juice to get to Oklahoma.

The February freeze illuminated two problems with electricity sufficiency. First, power plants had mechanical failures, triggering outages for days. But also, Texans demanded a lot more electricity than usual as heaters kicked on because of the cold. The ugly truth is, the Texas power grid probably couldn’t have generated enough electricity to meet demand, even if the plants kept whirring. And that is what should chill us now.

The stories of the people who died because the electricity went out during the freeze are difficult to read. A paletero and cotton-candy vendor well known in Old East Dallas, Leobardo Torres Sánchez, was found dead in his armchair, bundled in quilts beside two heaters that had no power.

Arnulfo Escalante Lopez, 41, and Jose Anguiano Torres, 28, died from carbon monoxide poisoning after using a gas-powered generator to heat their apartment in Garland.

Pramod Bhattarai, 23, a college student from Nepal, died from carbon monoxide after using a charcoal grill to heat his home in Houston, according to news reports. And Loan Le, 75; Olivia Nguyen, 11; Edison Nguyen, 8; and Colette Nguyen, 5, died in Sugar Land after losing control of a fire they started in the fireplace to keep warm.

A 65-year-old San Antonio man with esophageal cancer died after power outages cut off supply from his oxygen machine. And local Abilene media reported that a man died in a local hospital when a loss of water pressure prevented staff from treating him.

Gloria Jones of Hillsboro, 87, was living by herself, healthy and social. According to the Houston Chronicle, as the cold weather descended, she told her friends and family she was fine. But when her children checked on her after she didn’t answer her phone, they found her on the floor beside her bed. Hospital workers tried to warm her, but they soon pronounced her dead.

Officials said in July that 210 people died because of the freezing weather, including those who died in car crashes and other weather-related causes, but that figure will be updated. The Department of State Health Services said most of those deaths were due to hypothermia.


Policy recommendation: Weatherize power plants and fuel suppliers

Texas could have avoided those deaths if power plants had worked properly. It’s mechanically possible to generate electricity in freezing temperatures; the Swedes and Finns have electricity in winter. But preparing equipment for the winter costs money, and now that the Public Utility Commission set new requirements for plant owners to weatherize equipment, we expect better reliability.

The PUC officials certainly expect better performance. Chairman Peter Lake earlier this month promised: “We go into this winter knowing that because of all these efforts the lights will stay on.”

Yet, there’s no matching requirement to weatherize key fuel supplies for natural gas-fired power plants. While the PUC and the Electric Reliability Council of Texas were busy this year coming up with standards and enforcement processes, the Texas Railroad Commission, which regulates oil and gas production, was not.

The Railroad Commission is working to ensure that natural gas producers who supply power plants have filed the proper paperwork so that they do not lose electricity in a blackout, rendering them unable to provide vital fuel. But weatherization regulations will not happen for some months, not in time for this winter.


Policy recommendation: Combine the state’s Public Utility Commission and Railroad Commission into one energy agency

Electricity and natural gas regulators came to realize the importance of natural gas suppliers communicating their electricity needs with the PUC to avoid getting cut off when the fuel is needed the most. Not last year; they realized this ten years ago, when the same thing happened and triggered a day of rolling outages.

Why did it take a decade for the companies regulated by one agency to get their paperwork in order with a separate agency? It makes more sense for a single agency to regulate the entire energy process, from wellhead to lightbulb. (Or well-to-wheel, as cars increasingly need electricity, too.)

Over the years, various legislative sunset commissions have recommended combining the agencies, with different governance suggestions, none of which passed the Legislature. We urge lawmakers in 2023 to take up the idea in earnest, hammer out the governance details, and make sure the resulting agency has the heft and resources to regulate energy in a way that keeps the industry healthy and holds it accountable.


Policy recommendation: Incentivize building more power plants

Regardless, if energy companies in February had operated their equipment exactly right, the lights likely would have still gone out. Perhaps for a shorter period, perhaps in a more shared way, allowing people to keep homes above freezing and phones charged between rolling blackouts. But Texas was heading for trouble.

Before the winter freeze, ERCOT anticipated Texas would have 74,000 MW of power generation capacity for the winter of 2021. That’s less than the usual summer fleet as some plants go down for maintenance in the winter, but sufficient to meet their wildest predictions of winter electricity demand. The power generation on hand for the winter would have met the historic record winter demand, at 65,918 MW. Even in ERCOT’s planning scenario with extreme generator failures, the grid had enough capacity.

But during the second week of February, as weather forecasts became more dire, grid operators began rapidly hiking their estimates of electricity demand. On Valentine’s Day, ERCOT estimated demand would rise to 75,573 MW in the coming week.

Clearly that is more demand than all of Texas’ winter power generation fleet of 74,000 MW could handle. Demand never reached that level because ERCOT turned off service to millions of customers when power plants failed.

This raises questions about whether the Texas grid has enough power plants to remain resilient as climate change brings more frequent bouts of extreme weather and blackout risks across the U.S. Or if we have enough power to grow, as more people and companies, more homes and businesses and manufacturing plants, move to Texas.

What a shame if the Texas Miracle, our robust and growing economy, died because we ran out of electricity.

This is no exaggeration. In November, ERCOT released its seasonal assessment of whether Texas will have enough electricity resources for the coming winter. If weather is normal, yes, Texas will be in good shape. But if extreme weather again pushes Texas to use an inordinate amount of electricity for heat, and if wind and solar output are low, there won’t be enough. In that scenario, even if power plants mostly continue to operate properly, we should brace for outages.

Further, there are few investors planning to build more power plants in Texas, other than solar and wind. Renewable plants have many good qualities, but reliability isn’t one of them. Some investors are building grid-scale batteries, a technology that promises to add reliability to the grid.

How come power plant developers aren’t building more generators, especially with flat electricity demand in many markets today?


Policy recommendation: Incentivize reliability

The Texas electrical grid, independent of the rest of the U.S., operates as a competitive market. No regulator plans a power plant; investors choose to build plants based on expectations of profit.

How it works is, power generators offer their electricity into the market at the price of their choosing. ERCOT accepts the lowest bids first, working up to higher bids as demand for power increases in the course of a day.

The idea is that Texans always get the lowest possible price, and if prices rise high, investors will build more power plants. Basic supply and demand. When the market was first set up, this worked pretty well, because the big, reliable baseload generators, the coal and nuclear industries, were the cheapest to operate and bid their power at prices that kept them online all the time. The more agile natural gas-fired plants ramped up and down to meet demand minute-by-minute, at higher prices.

Renewable energy disrupts the market in ways that are great, generating cheap, clean power that has forced some high-polluting coal plants to mothball. But the disruption also undermines reliability. Wind and solar plants are the cheapest and quickest power generation to build and they have the lowest operating cost, allowing them to bid very low prices into the power market. Wind tends to blow hardest in West Texas at night, so the abundance of wind turbines has pushed many of those old baseload plants out of the market.

That’s how markets work, and we’re not crying for coal plant operators. But ERCOT has to figure out how to operate the market differently to keep the lights on.

The PUC announced a slew of electricity market reforms last week to address this very problem, including new to market pricing and an emergency reliability service for ERCOT to contract for more back-up power. These changes cost money, but failing to make any changes could cost more lives.

Texas became the No. 1 wind state thanks in part to a smart renewable energy credit system that created financial incentives to erect wind turbines. But those credits mean that sometimes at night, wind generators bid electricity into the market at negative prices, because they will make money off of the renewable energy credits.

It’s time for the Legislature to review the credit program to determine if it’s still needed, of a similar program could be added to incentivize reliability. The market-based program worked better than anyone could have expected to produce clean energy. Why not use this approach to create what we need now: clean and reliable energy?

We were pleased that PUC commissioners discussed last week an idea that would create a market for reliable power generation capacity by adding requirements that power market participants meet a standard of reliability guarantees.

A market for reliable electricity capacity will cost more, and we hope regulators keep the requirements as modest as possible. Renewable requirements were modest, but turned out to be powerful in a competitive market.

We expect a reliability program to be flexible enough that entrepreneurs can participate with new technology, such as batteries or geothermal energy or something that hasn’t been invented yet, rather than just old reliable fossil fuels.

We also welcome the PUC’s review of pricing rules for the market. Commissioners intend for a new pricing formula to offer early price signals of pending scarcity, to allow time for industrial customers to reduce consumption or suppliers to ramp up. This is intriguing, but we hope the final implementation keeps market interventions at a minimum.

We witnessed in February a scenario in which extremely high prices on the power market did nothing to attract more electricity into the market. Power plants broke down; there was no way to generate more power, no matter how high market prices went. So the PUC was silly to intervene in the market and keep prices artificially high; the outcome was billions of dollars of debt and a proposed electricity market bailout that electricity customers will end up paying.

Nor did this PUC pricing intervention prompt power generation developers to say: “I tell you what, let’s build more plants in Texas.” In the next few years, ERCOT can expect more solar power generation to come online, but little else.

Natural gas plant operators have told the PUC that market price signals show that a new plant wouldn’t be profitable. Natural gas plants are cheaper and faster to build than nuclear reactors; if those developers cannot figure out how to make money, then the prospect of a new nuclear reactor in Texas is a fantasy, even setting aside the environmental and political opposition.


Policy proposal: Use less energy

Politicians like to imagine that technology will solve our energy problem. But the quickest, cheapest, cleanest solution to all of our energy problems is to use less. Investing some federal infrastructure money to make homes more energy efficient would cut energy use, and could help homes retain heat in an emergency.

The PUC’s plan to offer more incentives for major power users to reduce demand in a grid emergency is a good idea. Bravo – next let’s take this benefit to the masses.

Upgrading building codes to require efficiency for office buildings and apartments can help, and might have prevented the frozen pipes in so many multifamily housing units that left people without water.

When North Texas power-line utility Oncor invested in smart grid technology in past decades, part of the promise was to help users reduce demand when electricity prices rise or in emergencies. A review and upgrade of the smart technology could allow more customers to benefit from discounts in exchange for turning things off when electricity supply is tight.

Problem is, we seem to be going in the opposite direction as consumers. Forget turning off the TV and unplugging the coffee machine as we leave the house each morning; now everything is always-on and always connected to Wi-Fi. Our appliances, electronics and the services that operate them can text us when anything interesting happens, like the laundry finishes or somebody opens the patio door or the first season of Murder She Wrote is available for streaming.

As Texans plug in electric vehicles, we will need even more power generation capacity. Researchers at the University of Texas at Austin estimated that if every Texan switched to an electric vehicle, demand for electricity would rise about 30%.

Texans will need to think realistically and rationally about where that electricity is going to come from. Before we march toward a utopian vision of an all-electric world, we need to make sure we have enough electricity.

Getting this right is a matter of life and death for each of one us and for Texas.

'Unlayering' peak demand could accelerate energy storage adoption

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

 

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

 

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

 

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

 

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.

Australian operator warns of reduced power reserves

Australia Electricity Supply Shortfall highlights AEMO's warning of reduced reserves as coal retirements outpace capacity, risking load shedding. Calls for 1GW strategic reserves and investment in renewables, storage, and dispatchable power in Victoria.

 

Key Points

It is AEMO's forecast of reduced reserves, higher outage risk, and a need for 1GW strategic backup capacity.

✅ Coal retirements outpacing firm, dispatchable capacity

✅ AEMO urges 1GW strategic reserves in Victoria and South Australia

✅ Investment needed: renewables, storage, grid and reliability services

 

Australia’s electricity operator has warned of threats to electricity supply including a shortfall in generation and reduced power reserves on the horizon.

The Australian Energy Market Operator (AEMO) has called for further investment in the country’s energy portfolio as retiring coal plants are replaced by intermittent renewables poised to eclipse coal, leaving the grid with less back-up capacity.

AEMO has said this increases the chances of supply interruption and load shedding.

It added the federal government should target 1GW of strategic reserves in the states most at risk – Victoria and South Australia, even as the Prime Minister has ruled out taxpayer-funded power plants in the current energy battle.

CEO of the Clean Energy Council, Kane Thornton, said the shortfall in generation, reflected in a short supply of electricity, was due a decade of indecisiveness and debate leading to a “policy vacuum”.

He added: “The AEMO report revealed that the new projects added to the system under the renewable energy target will help to improve reliability over the next few years.

“We need to accept that the energy system is in transition, with lessons from dispatchable power shortages in Europe, and long term policy is now essential to ensure private investment in the most efficient new energy technology and solutions.”

Florida PSC approves Gulf Power’s purchase of renewable energy produced at municipal solid waste plant

Gulf Power renewable energy contract underscores a Florida PSC-approved power purchase from Bay County's municipal solid waste plant, delivering 13.65 MW at a fixed price, boosting fuel diversity, lowering landfill waste, and saving customers money.

 

Key Points

A fixed-price PPA for 13.65 MW from Bay County's waste-to-energy plant, approved by Florida PSC to cut costs.

✅ Fixed-price purchase; pay only for energy produced.

✅ 13.65 MW from Bay County waste-to-energy facility.

✅ Cuts landfill waste and natural gas dependency.

 

The Florida Public Service Commission (PSC) approved Tuesday a contract under which Gulf Power Company will purchase all the electricity generated by the Bay County Resource Recovery Facility, a municipal solid waste plant, similar to SaskPower-Manitoba Hydro deal structures seen elsewhere, over the next six years.

“Gulf’s renewable energy purchase promotes Florida’s fuel diversity, further reducing our dependency on natural gas,” PSC Chairperson Julie Brown said. “This renewable energy option also reduces landfill waste, saves customers money, and serves the public interest.”

The contract provides for Gulf to acquire the Panama City facility’s 13.65 megawatts of renewable generation for its customers beginning in July 2017. Gulf will pay a fixed price, aligned with approaches in Alberta's clean electricity RFP programs, and only pays for the energy produced. The contract is expected to save approximately $250,000 and provides security for customers, a contrast to overruns at the Kemper power plant project, because if the plant does not supply energy, Gulf does not have to provide payment.

This contract is the third renewable energy contract between Gulf and Bay County, at a time when the Southern California plant closures may be postponed, continuing agreements approved in 2008 and 2014. In making the decision, the PSC considered Gulf’s need for power and developments such as the Turkey Point license renewal process, as well as the contract’s cost-effectiveness, payment provisions, and performance guarantees, as required by rule.
