Helping to meet ChinaÂ’s strict emission standards, Jiangsu Tianue Energy & Chemical Group Co. Ltd is building a high-efficiency gas turbine power plant to utilize industrial dismissed gas into power and steam to meet increasing energy needs in the region.

The power plant will be equipped with three GE aeroderivative gas turbines, which are the first LM2500+G4 units sold in China.

“GE’s innovative technology allows us to turn a previously environmentally harmful gas into a useful tool to produce energy for our customers. In addition, we will be able to reduce CO2 emissions by 300,000 tons per year and supply stable electricity to Pei County,” said Teng Daochun, chairman, Jiangsu Tianue Energy & Chemical Group Co. Ltd. “This project is an important step in increasing the value of coke oven gas.”

GEÂ’s LM2500+G4 aeroderivative gas turbines will use coke oven gas COG as fuel and turn it into electricity for the region. COG is a byproduct of the coking manufacturing process. Among all of the current treatment methods, GEÂ’s solution is more reliable, cleaner for the environment and uses the residual energy at a higher efficiency rate. GE also is providing a 12-year services agreement with one spare engine to ensure maximum operability at the new plant.

“Our LM2500+G4 is a powerful gas turbine with high efficiency, which has the potential to translate into operational savings and increased revenue potential for the customer’s operations,” said Darryl Wilson, vice president — aeroderivative gas turbines for GE Power & Water. “Using our aeroderivative technology for low-calorie, coke-oven gas is a technology breakthrough, and this project is another example of GE’s commitment to invest in progressive solutions to meet environmental challenges throughout the world. Through this endeavor, GE and Tianue are responding to the Chinese government’s call to reduce greenhouse gas emissions by conserving energy and making contributions to a cleaner economy in the country.”

The announcement is part of a series of commitments GE has made in China. On November 9, 2010, GE announced plans to invest more than $2 billion into its efforts in China through 2012 to help tackle the countryÂ’s pressing energy and infrastructure needs. GE Chairman and CEO Jeff Immelt announced that the company plans to commit $500 million to enhance China R&D capabilities and establish new Customer Innovation Centers to better serve west, north, central and south China.

On the same day, as part of the $2 billion investment, GE and State Grid Corporation of China SGCC, ChinaÂ’s top power distributor and one of the worldÂ’s largest utilities, announced plans for several joint ventures to address ChinaÂ’s growing energy needs and to electrify its vast transportation infrastructure. These joint ventures will play a vital role in supporting the countryÂ’s energy demand through the development of a smarter grid that will help achieve environmental and economical goals.

Time running out for Ontario to formally request Pickering nuclear power station extension

Pickering Nuclear Plant Extension faces CNSC approval as Ontario Power Generation pursues license renewal before the June 30, 2023 deadline, amid a 2025 capacity crunch and grid reliability risks from decommissioning and overlapping nuclear outages.

 

Key Points

A plan to run Pickering past 2024 to Sept 2026, pending CNSC license renewal to address Ontario's 2025 capacity gap.

✅ CNSC approval needed for operation beyond Dec 31, 2024

✅ OPG aims to file by June 30, 2023 deadline

✅ Extension targets grid reliability through 2026

 

Ontario’s electricity generator has yet to file an official application to extend the life of the Pickering nuclear power plant, more than eight months after the Ford government announced a plan to continue operating Pickering for longer.

As the province faces an electricity shortfall in 2025 and beyond, the Ford government scrambled to prolong the Pickering power plant until September 2026, in order to guarantee a steady supply of power as the province experiences a rise in demand and shutdowns at other nuclear power plants.

The life extension may come down to the wire, however, as the Canadian Nuclear Safety Commission (CNSC), the federal regulator tasked with approving or denying the extension, tells Global News the province has yet to file key paperwork.

The information is required for the application, including materials related to the proposed Pickering B refurbishment, and the government now has a month before the deadline runs out.

“The Commission requires that Ontario Power Generation submit specific information by June 30, 2023, if it intends to operate the Pickering Nuclear Generating Station beyond December 31, 2024,” the CNSC told Global News in a statement. “The Commission Registry has not yet received an application from Ontario Power Generation.”

If Ontario doesn’t receive the green light, the power plant which currently is responsible for 14 per cent of the province’s energy grid will be decommissioned in 2025, leaving the province with a significant electricity supply gap if replacement sources are not secured.

For its part, the Ford government doesn’t seem concerned about the impending timeline, even though the station was slated to close as planned, suggesting the Crown corporation responsible for the application will get it in on time.

“OPG is on track to submit their application before the end of June and has already started to submit supporting materials as part of the regulatory process toward clean power goals,” a spokesperson for energy minister Todd Smith said.

U.S. Electricity Sales Projections Continue to Fall

US Electricity Demand Outlook examines EIA forecasts, GDP decoupling, energy efficiency, electrification, electric vehicles, grid load growth, and weather variability to frame long term demand trends and utility planning scenarios.

 

Key Points

An analysis of EIA projections showing demand decoupling from GDP, with EV adoption and efficiency shaping future grid load.

✅ EIA lowers load growth; demand decouples from GDP.

✅ Efficiency and sector shifts depress kWh sales.

✅ EV adoption could revive load and capacity needs.

 

Electricity producers and distributors are in an unusual business. The product they provide is available to all customers instantaneously, literally at the flip of a switch. But the large amount of equipment, both hardware and software to do this takes years to design, site and install.

From a long range planning perspective, just as important as a good engineering design is an accurate sales projections. For the US electric utility industry the most authoritative electricity demand projec-tions come from the Department of Energy’s Energy Information Administration (EIA). EIA's compre-hensive reports combine econometric analysis with judgment calls on social and economic trends like the adoption rate of new technologies that could affect future electricity demand, things like LED light-ing and battery powered cars, and the rise of renewables overtaking coal in generation.

Before the Great Recession almost a decade ago, the EIA projected annual growth in US electricity production at roughly 1.5 percent per year. After the Great Recession began, the EIA lowered its projections of US electricity consumption growth to below 1 percent. Actual growth has been closer to zero. While the EIA did not antici-pate the last recession or its aftermath, we cannot fault them on that.

After the event, though, the EIA also trimmed its estimates of economic growth. For the 2015-2030 period it now predicts 2.1 percent economic and 0.3 percent electricity growth, down from previously projections of 2.7 percent and 1.3 percent respectively. (See Figures 1 and 2.)



 

Table 1. EIA electric generation projections by year of forecast (kWh billions)

 


 

Table 2. EIA forecast of GDP by year of forecast (billion 2009 $)

Back in 2007, the EIA figured that every one percent increase in economic activity required a 0.48 percent in-crease in electric generation to support it. By 2017, the EIA calculated that a 1 percent growth in economic activity now only required a 0.14 percent increase in electric output. What accounts for such a downgrade or disconnect between electricity usage and economic growth? And what factors might turn the numbers 
around?

First, the US economy lost energy intensive heavy industry like smelting, steel mills and refineries; patterns in China's electricity sector highlight how industrial shifts can reshape power demand. A more service oriented economy (think health care) relies more heavily on the movement of data or information and uses far less power than a manufacturing-oriented economy.

A small volcano in Argentina is about to fuel the next tech boom – and a little known company is going to be right at the center. Early investors stand to gain incredible profits and you can too. Read the report.

Second, internet shopping has hurt so-called "brick and mortar" retailers. Despite the departure of heavy industry, in years past a burgeoning US commercial sector increased its demand and usage of electricity to offset the industrial decline. But not anymore. Energy efficiency measures as well as per-haps greater concern about global warming and greenhouse gas emissions and have cut into electricity sales. “Do more with less” has the right ring to it.

But there may be other components to the ongoing decline in electricity usage. Academic studies show that electricity usage seems to increase with income along an S curve, and flattens out after a certain income level. That is, if you earn $1 billion per year you do not (or cannot) use ten times a much electricity as someone earning only $100 million.

But people at typical, middle income levels increase or decrease electricity usage when incomes rise or fall. The squeeze on middle income families was discussed often in the late presidential campaign. In recent decades an increasing percentage of income has gone to a small percentage of the population at the top of the income scale. This trend probably accounts for some weakness in residential sales. This suggests that government policy addressing income inequality would also boost electricity sales.

Population growth affects demand for electricity as well as the economy as a whole. The EIA has made few changes in its projections, showing 0.7 percent per year population growth in 2015- 2030 in both the 2007 and 2017 forecasts. Recent studies, however, have shown a drop in the birth rate to record lows. More troubling, from a national health perspective is that the average age of death may have stopped rising. Those two factors point to lower population growth, especially if the government also restricts immi-gration. Thus, the US may be approaching a period of rather modest population growth.

All of the above factors point to minimal sales growth for electricity producers in the US--perhaps even lower than the seemingly conservative EIA estimates. But the cloud on the horizon has a silver lining in the shape of an electric car. Both the United Kingdom and France have set dates to end of production of automobiles with internal combustion engines. Several European car makers have declared that 20 percent of their output will be electric vehicles by the early 2020s. If we adopt automobiles powered by electricity and not gasoline or diesel, electricity sales would increase by one third. For the power indus-try, electric vehicles represent the next big thing.

We don’t pretend to know how electric car sales will progress. But assume vehicle turnover rates re-main at the current 7 percent per year and electric cars account for 5 percent of sales in the first five years (as op-posed to 1 percent now), 20 percent in the next five years and 50 percent in the third five year period. Wildly optimistic assumptions? Maybe. By 2030, electric cars would constitute 28 percent of the vehicle fleet. They would add about 10 percent to kilowatt hour sales by that date, assuming that battery efficiencies do not improved by then. Those added sales would require increased electric generation output, with low-emissions sources expected to cover almost all the growth globally. They would also raise long term growth rates for 2015-2030 from the present 0.3 percent to 1.0 percent. The slow upturn in demand should give the electric companies time to gear up so to speak.

In the meantime, weather will continue to play a big role in electricity consumption. Record heat-induced demand peaks are being set here in the US even as surging global demand puts power systems under strain worldwide.

Can we discern a pattern in weather conditions 15 years out? Maybe we can, but that is one topic we don’t expect a government agency to tackle in public right now. Meantime, weather will affect sales more than anything else and we cannot predict the weather. Or can we?

New England Emergency fuel stock to cost millions

Inventoried Energy Program pays ISO-NE generators for fuel security to boost winter reliability, with FERC approval, covering fossil, nuclear, hydropower, and batteries, complementing capacity markets to enhance grid resilience during severe cold snaps.

 

Key Points

ISO-NE program paying generators to hold fuel or energy reserves for emergencies, boosting winter reliability.

✅ FERC-approved stopgap for 2023 and 2024 winter seasons

✅ Pays for on-site fuel or stored energy during cold-trigger events

✅ Open to fossil, nuclear, hydro, batteries; limited gas participation

 

Electricity ratepayers in New England will pay tens of millions of dollars to fossil fuel and nuclear power plants later this decade under a program that proponents say is needed to keep the lights on during severe winters but which critics call a subsidy with little benefit to consumers or the grid, even as Connecticut is pushing a market overhaul across the region.

Last week the Federal Energy Regulatory Commission said ISO-New England, which runs the six-state power grid, can create what it calls the Inventoried Energy Program or IEP. This basically will pay certain power plants to stockpile of fuel for use in emergencies during two upcoming winters as longer-term solutions are developed.

The federal commission called it a reasonable short-term solution to avoid brownouts which doesn’t favor any given technology.

Not all agree, however, including FERC Commissioner Richard Glick, who wrote a fiery dissent to the other three commissioners.

“The program will hand out tens of millions of dollars to nuclear, coal and hydropower generators without any indication that those payments will cause the slightest change in those generators’ behavior,” Glick wrote. “Handing out money for nothing is a windfall, not a just and reasonable rate.”

The program is the latest reaction by ISO-NE to the winter of 2013-14 when New England almost saw brownouts because of a shortage of natural gas to create electricity during a pair of week-long deep freezes.

ISO-New England says the situation is more critical now because of the possible retirement of the gas-fired Mystic Generating Station in Massachusetts. As with closed nuclear plants such as Vermont Yankee and Pilgrim in Massachusetts, power plant owners say lower electricity prices, partly due to cheap renewables and partly to stagnant demand, means they can’t be profitable just by selling power.

Programs like the IEP are meant to subsidize such plants – “incentivize” is the industry term – even though some argue there is no need to subsidize nuclear in deregulated markets so they’ll stay open if they are needed.

The IEP approved last week will be applied to the winters of 2023 and 2024, after a different subsidy program expires. It sets prices, despite warnings about rushing pricing changes from industry groups, for stocking certain amounts of fuel and payments during any “trigger” event, defined as a day when the average of high and low temperatures at Bradley International Airport in Connecticut is no more than 17 degrees Fahrenheit.

These payments will be made on top of a complex system of grid auctions used to decide how much various plants get paid for generating electricity at which times.

ISO-NE estimates the new program will cost between $102 million and $148 million each winter, depending on weather and market conditions.

It says the payments are open to plants that burn oil, coal, nuclear fuel, wood chips or trash; utility-scale battery storage facilities; and hydropower dams “that store water in a pond or reservoir.” Natural gas plants can participate if they guarantee to have fuel available, but that seems less likely because of winter heating contracts.

A major complaint and groups that filed petitions opposing the project is that ISO-NE presented little supporting evidence of how prices, amount and overall cost were determined. ISO-NE argued that there wasn’t time for such analysis before the Mystic shutdown, and FERC agreed.

“The proposal is a step in the right direction … while ISO-NE finishes developing a long-term market solution,” the commission said in its ruling.

The program is the latest example of complexities facing the nation’s electricity system evolves in the face of solar and wind power, which produce electricity so cheaply that they can render traditional power uneconomic but which can’t always produce power on demand, prompting discussions of Texas grid improvements among policymakers. Another major factor is climate change, which has increased the pressure to support renewable alternatives to plants that burn fossil fuels, as well as stagnant electricity demand caused by increased efficiency.

Opponents, including many environmental groups, say electricity utilities and regulators are too quick to prop up existing systems, as the 145-mile Maine transmission line debate shows, built when electricity was sent one way from a few big plants to many customers. They argue that to combat climate change as well as limit cost, the emphasis must be on developing “non-wire alternatives” such as smart systems for controlling demand, in order to take advantage of the current system in which electricity goes two ways, such as from rooftop solar back into the grid.

Nuclear alert investigation won't be long and drawn out, minister says

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."

Florida Court Blocks Push to Break Electricity Monopolies

Florida Electricity Deregulation Ruling highlights the Florida Supreme Court decision blocking a ballot measure on retail choice, preserving utility monopolies for NextEra and Duke Energy, while similar deregulation efforts arise in Virginia and Arizona.

 

Key Points

A high court decision removing a retail choice ballot measure, keeping Florida utility monopolies intact for incumbents.

✅ Petition language deemed misleading for 2020 ballot

✅ Preserves NextEra and Duke Energy market dominance

✅ Similar retail choice pushes in VA and AZ

 

Florida’s top court ruled against a proposed constitutional amendment that would have allowed customers to pick their electricity provider, even as Florida solar incentives face rejection by state leaders, threatening monopolies held by utilities such as NextEra Energy Inc. and Duke Energy Corp.

In a ruling Thursday, the court said the petition’s language is “misleading” and doesn’t comply with requirements to be included on the 2020 ballot, reflecting debates over electricity pricing changes at the federal level. The measure’s sponsor, Citizens for Energy Choice, said the move ends the initiative, even as electricity future advocacy continues nationwide.

“While we were confident in our plan to gather the remaining signatures required, we cannot overcome this last obstacle,” the group’s chair, Alex Patton, noting ongoing energy freedom in the South efforts, said in a statement.

The proposed measure was one of several efforts underway to deregulate U.S. electricity markets, including New York’s review of retail energy markets this year. Earlier this week, two Virginia state lawmakers unveiled a bill to allow residents and businesses to pick their electricity provider, threatening Dominion Energy Inc.’s longstanding local monopoly. And in Arizona, where Arizona Public Service Co. has long reigned, regulators are considering a similar move, while in New England Hydro-Quebec’s export bid has been energized by a court decision.

Ontario sending 200 workers to help restore power in Florida

Ontario Utilities Hurricane Irma Aid mobilizes Hydro One and Toronto Hydro crews to Tampa Bay, Florida, restoring power outages with bucket trucks, lineworkers, and mutual aid alongside Florida Power & Light after catastrophic damage.

 

Key Points

Mutual aid sending Hydro One and Toronto Hydro crews to Florida to restore power after Hurricane Irma.

✅ 205 workers, 52 bucket trucks, 30 support vehicles deployed

✅ Crews assist Tampa Bay under FPL mutual aid agreements

✅ Weeks-long restoration projected after catastrophic outages

 

Hurricane Irma has left nearly 7 million homes in the southern United States without power and two Ontario hydro utility companies are sending teams to help out as part of Canadian power crews responding to the disaster.

Toronto Hydro is sending 30 staffers to aid in the restoration efforts in Tampa Bay while Hydro One said Sunday night that it would send 175 employees after receiving a request from Florida Power and Light.

“I've been on other storms down in the states and they are pretty happy to see you especially when they find out you're from Canada,” Dean Edwards, one of the Hydro One employees heading to Florida, told CTV Toronto.

Most of the employees are expected to cross the border on Monday afternoon and arrive Wednesday.

Among the crews, Hydro One says it will send 150 lines and forestry staff, as well as 25 supporting resources, including mechanics, to help. Crews will bring 52 bucket trucks to Florida, as well as 30 other vehicles, reflecting their Ontario storm restoration experience with large-scale deployments, and pieces of equipment to transport and replace poles.

Hurricane Irma has claimed at least 45 lives in the Caribbean and United States thus far. Officials estimate that restoring power to Florida will take weeks to bring power back online.

“I’m sure a lot of people wish they could go down and help, fortunately our job is geared towards that so we're going to go down there to do our best and represent Canada,” said Blair Clarke, who’s making his first trip over the border.

Hydro One has reciprocal arrangements with other North American utilities to help with significant power outages, and its employees have provided COVID-19 support in Ontario as part of broader emergency efforts. All the costs are covered by the utility receiving the help.

In the past, the utility has sent crews to Massachusetts, Michigan, Florida, Ohio, Vermont, Washington, DC, and the Carolinas, while Sudbury Hydro crews have worked to reconnect service after storms at home as well. In 2012, 225 Hydro One employees travelled to Long Island, N.Y., to help out with Hurricane Sandy.

“This is what our guys and gals do,” Natalie Poole-Moffat, vice president of Corporate Affairs for Hydro One, told CP24. “They’re fabulous at it and we’re really proud of the work they do.”
