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.

How Electricity Gets Priced in Europe and How That May Change

EU Power Market Overhaul targets soaring electricity prices by decoupling gas from power, boosting renewables, refining price caps, and stabilizing grids amid inflation, supply shocks, droughts, nuclear outages, and intermittent wind and solar.

 

Key Points

EU plan to redesign electricity pricing, curb gas-driven costs, boost renewables, and protect consumers from volatility.

✅ Decouples power prices from marginal gas generation

✅ Caps non-gas revenues to fund consumer relief

✅ Supports grid stability with storage, demand response, LNG

 

While energy prices are soaring around the world, Europe is in a particularly tight spot. Its heavy dependence on Russian gas -- on top of droughts, heat waves, an unreliable fleet of French nuclear reactors and a continent-wide shift to greener but more intermittent sources like solar and wind -- has been driving electricity bills up and feeding the highest inflation in decades. As Europe stands on the brink of a recession, and with the winter heating season approaching, officials are considering a major overhaul of the region’s power market to reflect the ongoing shift from fossil fuels to renewables.

1. How is electricity priced? 
Unlike oil or natural gas, there’s no efficient way to save lots of electricity to use in the future, though projects to store electricity in gas pipes are emerging. Commercial use of large-scale batteries is still years away. So power prices have been set by the availability at any given moment. When it’s really windy or sunny, for example, then more is produced relatively cheaply and prices are lower. If that supply shrinks, then prices rise because more generators are brought online to help meet demand -- fueled by more expensive sources. The way the market has long worked is that it is that final technology, or type of plant, needed to meet the last unit of consumption that sets the price for everyone. In Europe this year, that has usually meant natural gas. 

2. What is the relationship between power and gas? 
Very close. Across western Europe, gas plants have been a vital part of the energy infrastructure for decades, with Irish price spikes highlighting dispatchable power risks, fed in large part by supplies piped in from Siberia. Gas-fired plants were relatively quick to build and the technology straightforward, at least compared with nuclear plants and burns cleaner than coal. About 18% of Europe’s electricity was generated at gas plants last year; in 2020 about 43% of the imported gas came from Russia. Even during the depths of the Cold War, there’d never been a serious supply problem -- until the relationship with Russia deteriorated this year after it invaded Ukraine. Diversifying away from Russia, such as by increasing imports of liquefied natural gas, requires new infrastructure that takes a lot of time and money.

3. Why does it work this way? 
In theory, the relationship isn’t different from that with coal, for example. But production hiccups and heatwave curbs on plants from nuclear in France to hydro in Spain and Norway significantly changed the generation picture this year, and power hit records as plants buckled in the heat. Since coal-fired and nuclear plants are generally running all the time anyway, gas plants were being called upon more often -- at times just to keep the lights on as summer temperatures hit records. And with the war in Ukraine resulting in record gas prices, that pushed up overall production costs. It’s that relationship that has made the surging gas price the driver for electricity prices. And since the continent is all connected, it has pushed up prices across the region. The value of the European power market jumped threefold last year, to a record 836 billion euros ($827 billion today).

4. What’s being considered? 
With large parts of European industry on its knees and households facing jumps in energy bills of several hundred percent, as record electricity prices ripple through markets, the pressure on governments and the European Union to intervene has never been higher. One major proposal is to impose a price cap on electricity from non-gas producers, with the difference between that and the market price channeled to relief for consumers. While it sounds simple, any such changes would rip up a market design that’s worked for decades and could threaten future investments because of unintended consequences.


5. How did this market evolve?
The Nordic region and the British market were front-runners in the 1990s, then Germany followed and is now the largest by far. A trader can buy and sell electricity delivered later on same day in blocks of an hour or even down to 15-minute periods, to meet sudden demand or take advantage of price differentials. The price for these contracts is decided entirely by the supply and demand, how much the wind is blowing or which coal plants are operating, for example. Demand tends to surge early in the morning and late afternoon. This system was designed when fossil fuels provided the bulk of power. Now there are more renewables, which are less predictable, with wind and solar surpassing gas in EU generation last year, and the proposed changes reflect that shift. 

6. What else have governments done?
There are also traders who focus on longer-dated contracts covering periods several years ahead, where broader factors such as expected economic output and the extent to which renewables are crowding out gas help drive prices. This year’s wild price swings have prompted countries including Germany, Sweden and Finland to earmark billions of euros in emergency liquidity loans to backstop utilities hit with sudden margin calls on their trading.

Ontario Providing Electricity Relief to Families, Small Businesses and Farms During COVID-19

Ontario TOU Electricity Rate Relief offers 24/7 fixed off-peak pricing at 10.1¢/kWh, suspending time-of-use tiers to support residential customers, small businesses, and farms, coordinated by the Ontario Energy Board during COVID-19.

 

Key Points

A 45-day policy fixing TOU power at 10.1¢/kWh 24/7 off-peak to ease costs for residents, small businesses, and farms.

✅ Applies 24/7 off-peak 10.1¢/kWh to all TOU electricity customers.

✅ Automatic bill credit; no application or enrollment required.

✅ Covers residential, small businesses, and farms; OEB coordination.

 

To support Ontarians through the rapidly evolving COVID-19 situation, the Government of Ontario is providing immediate electricity rate relief for families, small businesses and farms paying time-of-use (TOU) rates.

For a 45-day period, the government is working to suspend time-of-use electricity rates, holding electricity prices to the off-peak rate of 10.1 cents-per-kilowatt-hour. This reduced price will be available 24 hours per day, seven days a week to all time-of-use customers, who make up the majority of electricity consumers in the province. By switching to a fixed off-peak rate, time-of-use customers will see rate reductions of over 50 per cent compared to on-peak rates now in effect.

To deliver savings as quickly and conveniently as possible, this discount will be applied automatically to electricity bills without the need for customers to fill out an application form.

"During this unprecedented time, we are providing much-needed relief to Ontarians, specifically helping those who are doing the right thing by staying home and small businesses that have closed or are seeing fewer customers," said Premier Doug Ford. "By adopting a fixed, 24/7 off-peak rate, aligned with ultra-low overnight pricing options, we are making things a little easier during these difficult times and putting more money in people's pockets for other important priorities and necessities."

The Government of Ontario issued an Emergency Order under the Emergency Management and Civil Protection Act to apply the off-peak TOU electricity rate for residential, small businesses, and farm customers who currently pay TOU rates.

"Ontario is fortunate to have a strong electricity system we can rely on during these exceptional times, even as Ottawa's electricity consumption decreased during the pandemic, and our government is proud to provide additional relief to Ontarians who are doing their part to stay home," said Greg Rickford, Minister of Energy, Northern Development and Mines.

"We thank the Ontario Energy Board and our partners at local distribution companies across the province, including initiatives like Hydro One's Ultra-Low Overnight Price Plan that support customers, for taking quick action to make this change and provide immediate support for hardworking people of Ontario," said Bill Walker, Associate Minister of Energy.

Quick Facts

  • The Ontario Energy Board sets time-of-use electricity rates for residential and small business customers through the Regulated Price Plan, and provides stable electricity pricing for industrial and commercial companies through separate programs.
  • Time-of-use prices as of November, 2019 ― Off-Peak: 10.1₵/kWh, Mid-Peak: 14.4₵/kWh, On-Peak: 20.8₵/kWh
  • Depending on billing cycles, some customers will see these changes on their next electricity bill. TOU customers whose billing cycle ended before their local distribution company implemented this change will receive the reduced rate as a credit on a future bill.
  • The Ontario Electricity Rebate (OER) will continue to provide a 31.8 per cent rebate on the sub-total bill amount for all existing Regulated Price Plan (RPP) consumers.
  • There are approximately five million residential consumers, farms and some small businesses billed using time-of-use (TOU) electricity prices under the RPP.
  • The Ontario Energy Board has extended the winter ban on disconnections to July 31st.

Military Is Ramping Up Preparation For Major U.S. Power Grid Hack

DARPA RADICS Power Grid Security targets DoD resilience to cyber attacks, delivering early warning, detection, isolation, and characterization tools, plus a secure emergency network to protect critical infrastructure and speed grid restoration and communications.

 

Key Points

A DoD/DARPA initiative to detect, contain, and rapidly recover the U.S. grid from sophisticated cyber attacks.

✅ Early warning separates attacks from routine outages

✅ Pinpoints intrusion points and malware used

✅ Builds secure emergency network for rapid restoration

 

The U.S. Department of Defense is growing increasingly concerned about hackers taking down our power grid and crippling the nation, reflecting a renewed focus on grid protection across agencies, which is why the Pentagon has created a $77-million security plan that it hopes will be up and running by 2020.

The U.S. power grid is threatened every few days. While these physical and cyber attacks have never led to wide-scale outages, attacks are getting more sophisticated. According to a 494-page report released by the Department of Energy in January and a new grid report card, the nation’s grid “faces imminent danger from cyber attacks.” Such a major, sweeping attack could threaten “U.S. lifeline networks, critical defense infrastructure, and much of the economy; it could also endanger the health and safety of millions of citizens.” If it were to happen today, America could be powered-down and vulnerable for weeks.

#google#

The DoD is working on an automated system to speed up recovery time to a week or less — what it calls the Rapid Attack Detection, Isolation, and Characterization (RADICS) program. DARPA, the Pentagon’s research arm, originally solicited proposals in late 2015, asking for technology that did three things. Primarily, it had to detect early warning signs and distinguish between attacks and normal outages, especially after intrusions at U.S. electric utilities underscored the risk, but it also had to pinpoint the access point of the attack and determine what malicious software was used. Finally, it must include an emergency system that can rapidly connect various power-supply centers, without any human coordination. This would allow emergency and military responders to have an ad hoc communication system in place moments after an attack.

“If a well-coordinated cyberattack on the nation’s power grid were to occur today, the time it would take to restore power would pose daunting national security challenges,” said DARPA program manager John Everett, in a statement, at the time. “Beyond the severe domestic impacts, including economic and human costs, prolonged disruption of the grid would hamper military mobilization and logistics, impairing the government’s ability to project force or pursue solutions to international crises.”

DARPA plans to spend $77 million on RADICS, while DOE funding to improve the grid complements these initiatives. Last November, SRI International announced it had received $7.3 million from the program. In December, Raython was granted $9 million. The latest addition is BAE Systems, which received $8.6 million last month to develop technology that detects and contains power-grid threats, and creates a secure emergency provisional system that restores some power and communication in the wake of an attack — what is being called a secure emergency network.

According to the military news site Defense Systems, BAE’s SEN would rely on radio, satellite, or wireless internet — particularly as ransomware attacks continue to rise — whatever is available that allows the grid to continue working. The SEN would serve as a wireless connection between separate power grid stations.

While the ultimate goal of the RADICS program will be the restoration of civilian power and communications, the SEN will prioritize communication networks that would be used for defense or combat, so the U.S. government can still wage war while the rest of us are in the dark.

To further support customers who may be impacted by the pandemic, PG&E will offer its most flexible pay plans to customers who indicate either an impact or hardship as a result of COVID-19. PG&E will continue to monitor current events and identify opportunities to support our customers and communities through concrete actions.

In addition to the moratorium on service shut-offs, PG&E’s response to the COVID-19 pandemic is focused on efforts to protect the health and safety of its customers, employees, contractors and the communities it serves, including ongoing wildfire risk reduction efforts that continue alongside its pandemic response. Actions the company has taken include providing guidance for employees who have direct customer contact to take social distancing precautionary measures, such as avoiding handshakes and wearing disposable nitrile gloves while in customers' homes, and continuing safety work related to power line-related fires across its service area.

Customers who visit local offices to pay bills and are sick or experiencing symptoms are being asked to use other payment options such as online or by phone, as seen when Texas utilities waived fees during the pandemic, at 1-877-704-8470.

“We recognize that this is a rapidly changing situation and an uncertain time for many of our customers. Our most important responsibility is the health and safety of our customers and employees. We also want to provide some relief from the stress and financial challenges many are facing during this worldwide, public health crisis, and with rates set to stabilize in 2025 the company remains focused on affordability. We understand that many of our customers may experience a personal financial strain due to the slowdown in the economy related to the pandemic, and programs like the Wildfire Assistance Program can help eligible customers,” said Chief Customer Officer and Senior Vice President Laurie Giammona.

Internally, the company is taking advanced cleaning measures, communicating best practices frequently with employees, and is asking its leaders to let employees work remotely if their job allows, while avoiding critical business disruption. PG&E has activated an enterprise-wide incident response team and is vigilantly monitoring the Centers for Disease Control and Prevention and World Health Organization for updates related to the virus. The company is committed to continue addressing customer service needs and does not expect any disruption in gas or electric service due to the public health crisis.

Nova Scotia Power says it now generates 30 per cent of its power from renewables

Nova Scotia Power Renewable Energy delivers 30% in 2018, led by wind power, hydroelectric and biomass, with coal and natural gas declining, as Muskrat Falls imports from Labrador target 40% renewables to cut emissions.

 

Key Points

It is the utility's 30% 2018 renewable mix and plan to reach 40% via Muskrat Falls while reducing carbon emissions.

✅ 18% wind, 9% hydro and tidal, 3% biomass in 2018

✅ Coal reliance fell from 76% in 2007 to 52% in 2018

✅ 58% carbon emissions cut from 2005 levels projected by 2030

 

Nova Scotia's private utility says it has hit a new milestone in its delivery of electricity from renewable resources, a trend highlighted by Summerside wind generation in nearby P.E.I.

Nova Scotia Power says 30 per cent of the electricity it produced in 2018 came from renewable sources such as wind power.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke. Another 13 per cent come from burning natural gas and five per cent from imports, even as U.S. renewable generation hits record shares.

The utility says that since 2007, the province's reliance on coal-fired plants has dropped from 76 per cent of electricity generated to 52 per cent last year, as Prairie renewables growth accelerates nationally.

It says it expects to meet the province's legislated renewable target of 40 per cent in 2020, when it begins accessing hydroelectricity from the Muskrat Falls project in Labrador.

"We have made greener, cleaner energy a priority," utility president and CEO Karen Hutt said in a news release.

"As we continue to achieve new records in renewable electricity, we remain focused on ensuring electricity prices stay predictable and affordable for our customers, including solar customers across the province."

Nova Scotia Power also projects achieving a 58 per cent reduction in carbon emissions from 2005 levels by 2030.

Avista Commissions Largest Solar Array in Washington

Adams Nielson Solar Array, a 28 MW DC utility-scale project in Lind, WA, spans 200 acres with 81,700 panels, powering about 4,000 homes, supporting Avista’s Solar Select program and renewable energy, sustainability, and carbon reduction.

 

Key Points

Adams Nielson Solar Array is a 28 MW DC facility in Lind, WA, powering ~4,000 homes via Avista’s Solar Select.

✅ 81,700 panels across 200 acres in Eastern Washington

✅ Offsets emissions equal to removing 7,300 cars annually

✅ Collaboration by Avista, Strata Solar, WUTC, WSU Energy

 

Official commissioning of the Adams Nielson solar array located in Lind, WA occurred today. The 28 Megawatt DC array is comprised of 81,700 panels that span 200 acres and generates enough electricity to supply the equivalent of approximately 4,000 homes annually, similar to a new co-op solar project serving South Metro members.

“Avista’s interest in the development of Solar Select, a voluntary commercial solar program reflecting broader corporate adoption such as a corporate solar power plant commissioned by Arvato, is consistent with the Company’s ongoing commitment to provide customers with renewable energy choices at reasonable cost,” said Dennis Vermillion, president, Avista Corporation. “In recent years, an increasing number of Avista customers have expressed their expectations and challenges in acquiring renewable energy. Avista is pleased to lead this effort and develop renewable energy products that meet our customers’ needs today and into the future.” This interest is being generated by a mix of local and national customers across a variety of industries, including Huckleberry’s, Gonzaga University, Community Colleges of Spokane, Hotstart, Central Pre-Mix Concrete, a CRH Co., independently owned McDonald's franchise locations, Spokane City, Main Market and Community Building and VA Medical Center.

Jim Simon, director of sustainability at Gonzaga University said, “The Solar Select program helps Gonzaga University move even closer to achieving its goal of climate neutrality by 2050 by continuing to prioritize renewables in our energy portfolio, as other communities add projects like a municipal solar project to boost local supply. We are grateful for Avista’s leadership in this project and look forward to other opportunities to reduce our greenhouse gas emissions.”

Spokane Mayor David Condon said, “The City of Spokane is pleased to partner with Avista through the Solar Select Program, as we continue to seek out opportunities that are both environmentally and financially responsible. The City already is a net producer of energy, generating more clean, green energy than our use of electricity, natural gas, and fuel, a milestone also seen with North Carolina's first wind farm now fully operational. We are excited to add even more clean energy to power City Hall.”

The Solar Select program created a cost-effective structure to bring solar energy to large business customers in Eastern Washington, allowing them to advance their desired sustainability goals and benefiting from industry service innovations led by companies like Omnidian expanding their global reach. The array is projected to deliver the environmental benefit equivalent of more than 7,300 cars removed from the road each year. This renewable energy program was made possible through a collaboration of Avista, Strata Solar, the Washington Utilities and Transportation Commission, and the WSU Energy Program.
