A panel studying a deadly power plant explosion wants state regulators to consider stronger licensing and training rules on a common industrial pipe-cleaning practice used nationwide.

If adopted, the regulations would make Connecticut the first state to add extra oversight to the "gas blow" procedure, in which high-pressure natural gas is blown through pipes in some power plants and factories to clear debris.

Five workers were killed instantly and a sixth man died later of injuries from the February 7 blast at the under-construction Kleen Energy Systems plant in Middletown.

The plant exploded when something ignited the 400,000 cubic feet of gas and air that had accumulated in tight quarters during the gas blow procedure. The ignition source is still under investigation.

Retired U.S. District Court Judge Alan Nevas, chairman of the Connecticut panel that issued its recommendations Thursday, said government agency leaders in the group found that permits were in place for all of the regulated procedures at the plant.

But they also discovered that state law doesn't require special training, licensing or oversight for employees performing the gas blow — and their research found no such special regulations in other states, he said.

"This is a process that appears, to me at least, to have fallen between the cracks," Nevas said. "We live in a very highly regulated society, and to find that this was not regulated was surprising."

The law doesn't require companies to notify regulators and nearby residents before performing a gas blow.

It also doesn't address whether materials used have to meet certain standards, whether it should be prohibited during certain weather conditions that could affect how the gas disperses, and whether workers' hours should be limited so they aren't fatigued when they start the procedure.

State reviews of work records from contractors at the Kleen Energy plant found a majority of workers were on the job for more than 40 hours a week, and that some worked as many as 90 hours per week.

Linda Agnew, acting commissioner of the state Department of Labor, said there are no laws limiting work hours at private workplaces. She said their review found minor violations in record-keeping, but nothing suggesting those violations could be blamed for the long work hours or blast.

Gov. M. Jodi Rell created the panel to review the explosion and make recommendations to a second commission, which now receives the report that was just finalized. The second commission will report to Connecticut legislators in time for possible action in the 2011 legislative session, which starts in January.

Kleen Energy's permit for its Middletown plant construction expires November 30 of this year, so no new laws would be in place before it applies for renewal or an extension.

The panel advised the Connecticut Siting Council, which handles those permits, to include its recommendations as mandatory conditions if it renews the Kleen Energy permits.

Middletown detectives and state police are investigating whether any people or businesses should face criminal charges in connection with the explosion and deaths.

Robert Reardon, one of four attorneys representing 10 injured and deceased workers in civil lawsuits, said there is "no question in our minds" that the blast could have been avoided if the general contractor had faced the kind of stricter regulations that the commission advised.

"I think that the commission is on the right track. Unfortunately, sometimes industry has to be regulated by the state and federal government when they fail to regulate themselves properly, and this is one of these instances," Reardon said.

The U.S. Chemical Safety Board, which criticizes gas blows as inherently unsafe, also is investigating and plans to hold a June 28 public hearing in Portland, Conn., about dangers and alternatives to the procedure.

Several other industrial accidents involving natural gas have occurred in recent years, including one that killed four people last year at the ConAgra Foods Inc. plant in Garner, North Carolina, and another in 1999 at a Ford Motor Co. power plant in Dearborn, Michigan, that killed six.

Typical Ontario electricity bill set to increase nearly 2% as fixed pricing ends

Ontario Electricity Rates update: OEB sets time-of-use and tiered pricing for residential customers, with kWh charges for peak, mid-peak, and off-peak periods reflecting COVID-19 impacts on demand, supply costs, and pricing.

 

Key Points

Ontario Electricity Rates are OEB-set time-of-use and tiered prices that set per-kWh costs for residential customers.

✅ Time-of-use: 21.7 peak, 15.0 mid-peak, 10.5 off-peak cents/kWh

✅ Tiered: 12.6 cents/kWh up to 1000 kWh, then 14.6 cents/kWh

✅ Average 700 kWh home pays about $2.24 more per month

 

Energy bills for the typical Ontario home are going up by about two per cent with fixed pricing coming to an end on Nov. 1, the Ontario Energy Board says. 

The province's electricity regulator has released new time-of-use pricing and says the rate for the average residential customer using 700 kWh per month will increase by about $2.24.

The change comes as Ontario stretches into its eight month of the COVID-19 pandemic with new case counts reaching levels higher than ever seen before.

Time-of-use pricing had been scrapped for residential bills for much for the pandemic with a single fixed COVID-19 hydro rate set for all hours of the day. The move, which came into effect June 1, was meant "to support families, small business and farms while Ontario plans for the safe and gradual reopening of the province," the OEB said at the time.

Ontario later set the off-peak price until February 7 around the clock to provide additional relief.

Fixed pricing meant customers' bills reflected how much power they used, rather than when they used it. Customers were charged 12.8 cents/kWh under the COVID-19 recovery rate no matter their time of use.

Beginning November, the province says customers can choose between time-of-use and tiered pricing options. Rates for time-of-use plans will be 21.7 cents/kWh during peak hours, 15 cents/kWh for mid-peak use and 10.5 cents/kWh for off-peak use. 

Customers choosing tiered pricing will pay 12.6 cents/kWh for the first 1000 kWh each month and then 14.6 cents/kWh for any power used beyond that.

The energy board says the increase in pricing reflects "a combination of factors, including those associated with the COVID-19 pandemic, that have affected demand, supply costs and prices in the summer and fall of 2020."

Asked for his reaction to the move Tuesday, Premier Doug Ford said, "I hate it," adding the province inherited an energy "mess" from the previous Liberal government and are "chipping away at it."

NRC Makes Available Turkey Point Renewal Application

Turkey Point Subsequent License Renewal seeks NRC approval for FP&L to extend Units 3 and 4, three-loop pressurized water reactors near Homestead, Miami; public review, docketing, and an Atomic Safety and Licensing Board hearing.

 

Key Points

The NRC is reviewing FP&L's request to extend Turkey Point Units 3 and 4 operating licenses by 20 years.

✅ NRC will docket if application is complete

✅ Public review and opportunity for adjudicatory hearing

✅ Units commissioned in 1972 and 1973, near Miami

 

The U.S. Nuclear Regulatory Commission said Thursday that it had made available the first-ever "subsequent license renewal application," amid milestones at nuclear power projects worldwide, which came from Florida Power and Light and applies to the company's Turkey Point Nuclear Generating Station's Units 3 and 4.

The Nuclear Regulatory Commission recently made available for public review the first-ever subsequent license renewal application, which Florida Power & Light Company submitted on Jan. 1.

In the application, FP&L requests an additional 20 years for the operating licenses of Turkey Point Nuclear Generating Units 3 and 4, three-loop, pressurized water reactors located in Homestead, Florida, where the Florida PSC recently approved a municipal solid waste energy purchase, approximately 40 miles south of Miami.

The NRC approved the initial license renewal in June 2002, as new reactors at Georgia's Vogtle plant continue to take shape nationwide. Unit 3 is currently licensed to operate through July 19, 2032. Unit 4 is licensed to operate through April 10, 2033.

NRC staff is currently reviewing the application, while a new U.S. reactor has recently started up, underscoring broader industry momentum. If the staff determines the application is complete, they will docket it and publish a notice of opportunity to request an adjudicatory hearing before the NRC’s Atomic Safety and Licensing Board.

The first-ever subsequent license renewal application, submitted by Florida Power & Light Company asks for an additional 20 years for the already-renewed operating licenses of Turkey Point, even as India moves to revive its nuclear program internationally, which are currently set to expire in July of 2032 and April of 2033. The two thee-loop, pressurized water reactors, located about 40 miles south of Miami, were commissioned in July 1972 and April 1973.

If the application is determined to be complete, the staff will docket it and publish a notice of opportunity to request an adjudicatory hearing before the NRC’s Atomic Safety and Licensing Board, the agency said.

The application is available for public review on the NRC website. Copies of the application will be available at the Homestead Branch Library in Homestead, the Naraja Branch Library in Homestead and the South Dade Regional Library in Miami.

Magnitude 5 quake strikes near Iran nuclear plant

Iran Bushehr Earthquake rattles southern province near the Bushehr nuclear power plant, USGS reports M5.1 at 38 km depth; seismic activity along major fault lines raises safety, damage, and monitoring concerns.

 

Key Points

A magnitude 5.1 quake near Bushehr nuclear plant at 38 km depth, with no damage reported, per USGS.

✅ USGS lists magnitude 5.1 at 38 km depth

✅ Near Bushehr nuclear power plant; built for stronger quakes

✅ Iran lies on major fault lines; quake risk is frequent

 

A magnitude 5 earthquake struck southern Iran early Friday near the Islamic Republic's only nuclear power plant. There were no immediate reports of damage or injuries as Iran continues combined-cycle conversions across its power sector.

The quake hit Iran's Bushehr province at 5:23 a.m., according to the U.S. Geological Survey. It put the magnitude at 5.1 and the depth of the earthquake at 38 kilometres (24 miles), in a province tied to efforts to transmit electricity to Europe in coming years.

Iranian state media did not immediately report on the quake. However, the Bushehr nuclear power plant was designed to withstand much stronger earthquakes, a notable consideration as Iraq plans nuclear power plants to address shortages.

A magnitude 5 earthquake can cause considerable damage, including power disruptions that have seen blackouts spark protests in some Iranian cities.

Iran sits on major fault lines and is prone to near-daily earthquakes, yet it remains a key player in regional power, with Iran-Iraq energy cooperation ongoing. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people, and today Iran supplies 40% of Iraq's electricity through cross-border power deals. Bam is near the Bushehr nuclear plant, which wasn’t damaged at that time, while more recently Iran finalized deals to rehabilitate Iraq's power grid to improve resilience.

Romania moves to terminate talks with Chinese partner in nuke project

Romania Ends CGN Cernavoda Nuclear Deal, as Nuclearelectrica moves to terminate negotiations on reactors 3 and 4, citing the EU Green Deal, US partnership, NATO, and a shift to alternative nuclear capacity options.

 

Key Points

Romania orders Nuclearelectrica to end CGN talks on Cernavoda units 3-4 and pursue alternative nuclear options.

✅ Negotiations on Cernavoda units 3-4 to be formally terminated

✅ EU Green Deal and US partnership cited over security concerns

✅ Board to draft strategies for new domestic nuclear capacity

 

Romania's government has mandated the managing board of local nuclear power producer Nuclearelectrica to initiate procedures for terminating negotiations with China General Nuclear Power Group (CGN) on building two new reactors at the Cernavoda nuclear power plant, where IAEA safety reports continue to shape operations.

The government also mandated the managing board to analyse and draw up strategic options on the construction of new electricity generation capacities from nuclear sources, as other countries such as India take steps to get nuclear back on track in response to demand.

The company will negotiate the termination of the agreement signed in 2015 for developing and operating units 3 and 4 at Cernavoda, even as Germany turns away from nuclear within the European landscape. 

At the end of last month, Economy Minister Virgil Popescu said that the collaboration with the Chinese company couldn't continue as it has yielded no results in seven years, despite China's nuclear program expanding steadily elsewhere.

"We have a strategic partnership with the US, and we hold on to it, we respect our partners. We are members of the EU and Nato, even as Germany's final reactor closures unfold in Europe. Aside from that, I think that seven years since this collaboration with the Chinese company began is enough to realise that we can't move on," Popescu said at that time.

Liberal Prime Minister Ludovic Orban announced in January that the government would exit the deal with its Chinese partner. He invoked the European Union's Green Deal rather than security issues or cost concerns circulated previously as the main reason behind a potential end of the deal with CGN to expand Romania's only nuclear power plant, amid concerns that Europe is losing nuclear power when it needs energy.

In August last year, the US included CGN on a blacklist for allegedly trying to get nuclear technology from the US to be used for military purposes in China, even as nuclear cooperation with Cambodia expands in the region.

British Columbia Accelerates Clean Energy Shift

BC Hydro Grid Modernization accelerates clean energy and electrification, upgrading transmission lines, substations, and hydro dams to deliver renewable power for EVs and heat pumps, strengthen grid reliability, and enable industrial decarbonization in British Columbia.

 

Key Points

A $36B, 10-year plan to expand and upgrade B.C.'s clean grid for electrification, reliability, and industrial growth.

✅ $36B for lines, substations, and hydro dam upgrades

✅ Enables EV charging, heat pumps, and smart demand response

✅ Prioritizes industrial electrification and Indigenous partnerships

 

In a significant move towards a clean energy transition, British Columbia has announced a substantial $36-billion investment to enlarge and upgrade its electricity grid over the next ten years. The announcement last Tuesday from BC Hydro indicates a substantial 50 percent increase from its prior capital plan. A major portion of this investment is directed towards new consumer connections and improving current infrastructure, including substations, transmission lines, and hydro dams for more efficient power generation.

The catalyst behind this major investment is the escalating demand for clean energy across residential, commercial, and industrial sectors in British Columbia. Projections show a 15 percent rise in electricity demand by 2030. According to the Canadian Climate Institute's models, achieving Canada’s climate goals will require extensive electrification across various sectors, raising questions about a net-zero grid by 2050 nationwide.

BC Hydro is planning substantial upgrades to the electrical grid to meet the needs of a growing population, decreasing industry carbon emissions, and the shift towards clean technology. This is vital, especially as the province works towards improving housing affordability and as households face escalating costs from the impacts of climate change and increasing exposure to harsh weather events. Affordable, reliable power and access to clean technologies such as electric vehicles and heat pumps are becoming increasingly important for households.

British Columbia is witnessing a significant shift from fossil fuels to clean electricity in powering homes, vehicles, and workplaces. Electric vehicle usage in B.C. has increased twentyfold in the past six years. Last year, one in every five new light-duty passenger vehicles sold in B.C. was electric – the highest rate in Canada. Additionally, over 200,000 B.C. homes are now equipped with heat pumps, indicating a growing preference for the province’s 98 percent renewable electricity.

The investment also targets reducing industrial emissions and attracting industrial investment. For instance, the demand for transmission along the North Coastline, from Prince George to Terrace, is expected to double this decade, especially from sectors like mining. Mining companies are increasingly looking for locations with access to clean power to reduce their carbon footprint.

This grid enhancement plan in B.C. is reflective of similar initiatives in provinces like Quebec and the legacy of Manitoba hydro history in building provincial systems. Hydro-Québec announced a substantial $155 to $185 billion investment in its 2035 Action Plan last year, aimed at supporting decarbonization and economic growth. By 2050, Hydro-Québec predicts a doubling of electricity demand in the province.

Both utilities’ strategies focus on constructing new facilities and enhancing existing assets, like upgrading dams and transmission lines. Hydro-Québec, for instance, includes energy efficiency goals in its plan to double customer savings and potentially save over 3,500 megawatts of power.

However, with this level of investment, provinces need to engage in dialogue about priorities and the optimal use of clean electricity resources, with concepts like macrogrids offering potential benefits. Quebec, for instance, has shifted from a first-come, first-served basis to a strategic review process for significant new industrial power requests.

B.C. is also moving towards strategic prioritization in its energy strategy, evident in its recent moratorium on new connections for virtual currency mining due to their high energy consumption.

Indigenous partnership and leadership are also key in this massive grid expansion. B.C.’s forthcoming Call for Power and Quebec’s financial partnerships with Indigenous communities indicate a commitment to collaborative approaches. British Columbia has also allocated $140 million to support Indigenous-led power projects.

Regarding the rest of Canada, electricity planning varies in provinces with deregulated markets like Ontario and Alberta. However, these provinces are adapting too, and the federal government has funded an Atlantic grid study to improve regional planning efforts. Ontario, for example, has provided clear guidance to its system operator, mirroring the ambition in B.C. and Quebec.

Utilities are rapidly working to not only expand and modernize energy grids but also to make them more resilient, affordable, and smarter, as demonstrated by recent California grid upgrades funding announcements across the sector. Hydro-Québec focuses on grid reliability and affordability, while B.C. experiments with smart-grid technologies.

Both Ontario and B.C. have programs encouraging consumers to reduce consumption in real-time, demonstrating the potential of demand-side management. A recent instance in Alberta showed how customer participation could prevent rolling blackouts by reducing demand by 150 megawatts.

This is a crucial time for all Canadian provinces to develop larger, smarter energy grids, including a coordinated western Canadian electricity grid approach for a sustainable future. Utilities are making significant strides towards this goal.

Are Norwegian energy firms ‘best in class’ for environmental management?

CO2 Tax for UK Offshore Energy Efficiency can accelerate adoption of aero-derivative gas turbines, flare gas recovery, and combined cycle power, reducing emissions on platforms like Equinor's Mariner and supporting net zero goals.

 

Key Points

A carbon price pushing operators to adopt efficient turbines, flare recovery, and combined cycle to cut emissions.

✅ Aero-derivative turbines beat industrial units on efficiency

✅ Flare gas recovery cuts routine flaring and fuel waste

✅ Combined cycle raises efficiency and lowers emissions

 

By Tom Baxter

The recent Energy Voice article from the Equinor chairman concerning the Mariner project heralding a ‘significant point of reference’ for growth highlighted the energy efficiency achievements associated with the platform.

I view energy efficiency as a key enabler to net zero, and alongside this the UK must start large-scale storage to meet system needs; it is a topic I have been involved with for many years.

As part of my energy efficiency work, I investigated Norwegian practices and compared them with the UK.

There were many differences, here are three;


1. Power for offshore installations is usually supplied from gas turbines burning fuel from the oil and gas processing plant, and even as the UK's offshore wind supply accelerates, installations convert that to electricity or couple the gas turbine to a machine such as a gas compressor.

There are two main generic types of gas turbine – aero-derivative and industrial. As the name implies aero-derivatives are aviation engines used in a static environment. Aero-derivative turbines are designed to be energy efficient as that is very import for the aviation industry.

Not so with industrial type gas turbines; they are typically 5-10% less efficient than a comparable aero-derivative.

Industrial machines do have some advantages – they can be cheaper, require less frequent maintenance, they have a wide fuel composition tolerance and they can be procured within a shorter time frame.

My comparison showed that aero-derivative machines prevailed in Norway because of the energy efficiency advantages – not the case in the UK where there are many more offshore industrial gas turbines.

2. Offshore gas flaring is probably the most obvious source of inefficient use of energy with consequent greenhouse gas emissions.

On UK installations gas is always flared due to the design of the oil and gas processing plant.

Though not a large quantity of gas, a continuous flow of gas is routinely sent to flare from some of the process plant.

In addition the flare requires pilot flames to be maintained burning at all times and, while Europe explores electricity storage in gas pipes, a purge of hydrocarbon gas is introduced into the pipes to prevent unsafe air ingress that could lead to an explosive mixture.

On many Norwegian installations the flare system is designed differently. Flare gas recovery systems are deployed which results in no flaring during continuous operations.

Flare gas recovery systems improve energy efficiency but they are costly and add additional operational complexity.


3. Returning to gas turbines, all UK offshore gas turbines are open cycle – gas is burned to produce energy and the very hot exhaust gases are vented to the atmosphere. Around 60 -70% of the energy is lost in the exhaust gases.

Some UK fields use this hot gas as a heat source for some of the oil and gas treatment operations hence improving energy efficiency.

There is another option for gas turbines that will significantly improve energy efficiency – combined cycle, and in parallel plans for nuclear power under the green industrial revolution aim to decarbonise supply.

Here the exhaust gases from an open cycle machine are taken to a separate turbine. This additional turbine utilises exhaust heat to produce steam with the steam used to drive a second turbine to generate supplementary electricity. It is the system used in most UK power stations, even as UK low-carbon generation stalled in 2019 across the grid.

Open cycle gas turbines are around 30 – 40% efficient whereas combined cycle turbines are typically 50 – 60%. Clearly deploying a combined cycle will result in a huge greenhouse gas saving.

I have worked on the development of many UK oil and gas fields and combined cycle has rarely been considered.

The reason being is that, despite the clear energy saving, they are too costly and complex to justify deploying offshore.

However that is not the case in Norway where combined cycle is used on Oseberg, Snorre and Eldfisk.

What makes the improved Norwegian energy efficiency practices different from the UK – the answer is clear; the Norwegian CO2 tax.

A tax that makes CO2 a significant part of offshore operating costs.

The consequence being that deploying energy efficient technology is much easier to justify in Norway when compared to the UK.

Do we need a CO2 tax in the UK to meet net zero – I am convinced we do. I am in good company. BP, Shell, ExxonMobil and Total are supporting a carbon tax.

Not without justification there has been much criticism of Labour’s recent oil tax plans, alongside proposals for state-owned electricity generation that aim to reshape the power market.

To my mind Labour’s laudable aims to tackle the Climate Emergency would be much better served by supporting a CO2 tax that complements the UK's coal-free energy record by strengthening renewable investment.
