The Duke Energy Kentucky Inc. unit of Duke Energy Corp. told the Kentucky Public Service Commission in a Sept. 29 filing that appeals court rulings striking down two federal air emissions rules are having little effect at the moment on its coal-fired power facilities.

DE-Kentucky was answering a question posed by the PSC as part of an ongoing integrated resource plan review process. The commission asked about the impact earlier this year of two federal appeals courts striking down the federal Clean Air Interstate Rule and the companion Clean Air Mercury Rule.

"The recent court decision to vacate the CAIR (& CAMR) results in DE-Kentucky being required to continue to comply with the existing Acid Rain SO2 cap & trade program and the ozone season NOx Budget Trading Program," said the utility. "However, states will immediately begin to revise their State Implementation Plans to attain the fine particulate matter National Ambient Air Quality Standard, since their previous submittal relied on CAIR.

It is likely that equipment installed to comply with CAlR will be mandated to operate annually to meet new SIP requirements very soon. Furthermore, in order to address emissions transport, the U.S. Congress may act to reinstate CAIR or more stringent multi-pollutant legislation or states may file Section 126 petitions with USEPA against upwind states. DE-Kentucky is actively monitoring these activities."

DE-Kentucky was also asked about plans to operate the selective catalytic reduction system for NOx control at the East Bend plant for an additional time in 2008 in order to earn NOx Compliance Supplement Pool Allowances.

"With the court decision to vacate CAIR, there is no immediate requirement to operate the East Bend Station SCR outside of the ozone season — either to earn early reduction credits or the January 2009 implementation date. However, as stated in [the prior answer about CAIR and CAMR being struck down], the Kentucky DEP will be revising its fine particulate matter SIP very quickly and will likely require the operation of installed controls to attain the NAAQS."

In response to another PSC question, DE-Kentucky attached a fact sheet describing a small CO2 sequestration demonstration project at East Bend. "Duke Energy has volunteered to take part in a field test of a promising technique for permanently storing carbon dioxide deep under its East Bend Generating Station," according to the fact sheet. "The test is one of several being conducted in the Midwest by the U.S. Department of Energy's (USDOE's) Midwest Regional Carbon Sequestration Partnership (MRCSP)."

DE-Kentucky added: "Although the field test at East Bend is a very small-scale test, it represents an important step in building our knowledge and helping future generations to address climate change. If successful, geologic sequestration could also be economically important to Kentucky and other Midwestern states by allowing the region to produce carbon-neutral, affordable energy to support our region's economy in the future."

DE-Kentucky said various project activities will be spread over a period of about three years. The exact timing of individual activities will depend on what is learned during the previous step, as well as on the availability of needed equipment. Before injecting CO2, Duke Energy will prepare an application for a permit to the U.S. Environmental Protection Agency Region 4 office.

The permit application requires an operational plan, which will include factors such as determining the pressure at which the CO2 should be injected and a plan for monitoring the safety of the operations. These activities are expected to take place during 2008.

In the project, a very small amount of CO2 will be injected over a period of one to three months. Before injection, the CO2 will be compressed to a liquid-like state. It will then be injected through a well into rock formations filled with saline water. Injection will occur at a depth of 3,000 to 3,500 feet, far below drinking water sources, which are at a depth of less than 100 feet in this region.

Nuclear helps Belgium increase electricity exports in 2019

Belgium Energy Mix 2019 shows strong nuclear output, rising offshore wind, net electricity exports, and robust interconnections, per Elia, as the nuclear phaseout drives 3.9GW new capacity needs after improved reactor availability.

 

Key Points

High nuclear share, offshore wind, net exports, interconnections; 3.9GW capacity needed amid nuclear phaseout.

✅ Nuclear supplied 48.8% of generation in 2019.

✅ Net exporter: 1.8 TWh, aided by interconnections.

✅ Elia projects 3.9GW new capacity for phaseout.

 

Belgium's electricity transmission system operator, Elia, said that the major trends in 2019 were a steady increase in (mainly offshore) renewable power generation, illustrated by EU wind and solar records across the bloc, better availability of nuclear-generating facilities and an increase in electricity exports.

In 2019, 48.8% of the power generated in Belgium came from nuclear plants. This was in line with the total for 2017 (50%) and significantly more than in 2018 (31.2%) when several reactors were unavailable amid stunted hydro and nuclear output in Europe as well.

Belgium exported more electricity in 2019, as neighbors like Germany saw renewables overtake coal and nuclear generation, with net exports of 1.8TWh (2.1% of the energy mix), in contrast to 2018 when Belgium imported 17.5TWh (20%).

Elia said this “should be viewed in its wider context, of declining nuclear capacity in Europe and regional market shifts, against the backdrop of an increasingly Europeanised market, and can be explained primarily by the good availability of Belgium's generating facilities (especially its nuclear power stations).”

The development of interconnections was also a key factor in the circulation of these electricity flows, as seen with Irish grid price spikes highlighting regional stress, Elia noted.

“Belgium had not been a net exporter of electricity for almost 10 years, the last time being in 2009 and 2010, when total net exports represented 2.8% and 0.2% respectively of Belgium’s energy mix,” it said.

Belgian has seven nuclear reactors – three at Tihange near Liege and four at Doel near Antwerp – and, regionally, nuclear-powered France faces outage risks that influence cross-border reliability.

In 2003, Belgium decided to phase out nuclear power and passed a law to that effect, with neighbors like Germany navigating a balancing act during their energy transition, which was reaffirmed in 2015 and 2018.

A commission appointed to assess the impact of the nuclear phaseout is scheduled to be completed in 2025 but has yet to report any findings.

Elia estimates that some 3.9GW of new power generating capacity will be needed to compensate for Belgium's nuclear phaseout.

Nova Scotia can't order electric utility to lower power rates, minister says

Nova Scotia Power Rate Regulation explains how the privately owned utility is governed by the Utility Review Board, limiting government authority, while COVID-19 relief measures include suspended disconnections, waived fees, payment plans, and emergency assistance.

 

Key Points

URB oversight where the board, not the province, sets power rates, with COVID-19 relief pausing disconnections and fees.

✅ Province lacks authority to order rate cuts

✅ URB regulates Nova Scotia Power rates

✅ Relief: no disconnections, waived fees, payment plans

 

The province can't ask Nova Scotia Power to lower its rates to ease the financial pressure on out-of-work residents because it lacks the authority to take that kind of action, even as the Nova Scotia regulator approved a 14% hike in a separate proceeding, the provincial energy minister said Thursday.

Derek Mombourquette said he is in "constant contact" with the privately owned utility.

"The conversations are ongoing with Nova Scotia Power," he said after a cabinet meeting.

When asked if the Liberal government would order the utility to lower electricity rates as households and businesses struggle with the financial fallout from the COVID-19 pandemic, Mombourquette said there was nothing he could do.

"We don't have the regulatory authority as a government to reduce the rates," he told reporters during a conference call.

"They're independent, and they are regulated through the (Nova Scotia Utility Review Board). My conversations with Nova Scotia Power essentially have been to do whatever they can to support Nova Scotians, whether it's residents or businesses in this very difficult time."

Asked if the board would take action, the minister said: "I'm not aware of that," despite the premier's appeals to regulators in separate rate cases.

However, the minister noted that the utility, owned by Emera Inc., has suspended disconnections for bill non-payment for at least 90 days, a step similar to reconnection efforts by Hydro One announced in Ontario.

It has also relaxed payment timelines and waived penalties and fees, while some jurisdictions offered lump-sum credits to help with bills.

Nova Scotia Power CEO Wayne O'Connor has also said the company is making additional donations to a fund available to help low-income individuals and families pay their energy bills.

In late March, Ontario cut electricity rates for residential consumers, farms and small businesses in response to a surge in people forced to work from home as a result of the pandemic, alongside bill support measures for ratepayers.

Premier Doug Ford said there would be a 45-day switch to off-peak rates, later moving to a recovery rate framework, which meant electricity consumers would be paying the lowest rate possible at any time of day.

The change was expected to cost the province about $162 million.

N.S. approves new attempt to harness Bay of Fundy's powerful tides

Bay of Fundy Tidal Energy advances as Nova Scotia permits Jupiter Hydro to test floating barge platforms with helical turbines in Minas Passage, supporting renewable power, grid-ready pilots, and green jobs in rural communities.

 

Key Points

A Nova Scotia tidal energy project using helical turbines to generate clean power and create local jobs.

✅ Permits enable 1-2 MW prototypes near Minas Passage

✅ Floating barge platforms with patented helical turbines

✅ PPA at $0.50/kWh with Nova Scotia Power

 

An Alberta-based company has been granted permission to try to harness electricity from the powerful tides of the Bay of Fundy.

Nova Scotia has issued two renewable energy permits to Jupiter Hydro.

Backers have long touted the massive energy potential of Fundy's tides -- they are among the world's most powerful -- but large-scale commercial efforts to harness them have borne little fruit so far, even as a Scottish tidal project recently generated enough power to supply nearly 4,000 homes elsewhere.

The Jupiter application says it will use three "floating barge type platforms" carrying its patented technology. The company says it uses helical turbines mounted as if they were outboard motors.

"Having another company test their technology in the Bay of Fundy shows that this early-stage industry continues to grow and create green jobs in our rural communities," Energy and Mines Minister Derek Mombourquette said in a statement.

The first permit allows the company to test a one-megawatt prototype that is not connected to the electricity grid.

The second -- a five-year permit for up to two megawatts -- is renewable if the company meets performance standards, environmental requirements and community engagement conditions.

Mombourquette also authorized a power purchase agreement that allows the company to sell the electricity it generates to the Nova Scotia grid through Nova Scotia Power for 50 cents per kilowatt hour.

On its web site, Jupiter says it believes its approach "will prove to be the most cost effective marine energy conversion technology in the world," even as other regional utilities consider initiatives like NB Power's Belledune concept for turning seawater into electricity.

The one megawatt unit would have screws which are about 5.5 metres in diameter.

The project is required to obtain all other necessary approvals, permits and authorizations.

It will be located near the Fundy Ocean Research Center for Energy in the Minas Passage and will use existing electricity grid connections.

A study commissioned by the Offshore Energy Research Association of Nova Scotia says by 2040, the tidal energy industry could contribute up to $1.7 billion to Nova Scotia's gross domestic product and create up to 22,000 full-time jobs, a transition that some argue should be planned by an independent body to ensure reliability.

Last month, Nova Scotia Power said it now generates 30 per cent of its power from renewables, as the province moves to increase wind and solar projects after abandoning the Atlantic Loop.

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 across its fleet.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke, even as environmental advocates push to reduce biomass use in the mix. Another 13 per cent come from burning natural gas and five per cent from imports.

Blackout-Prone California Is Exporting Its Energy Policies To Western States, Electricity Will Become More Costly And Unreliable

California Blackouts expose grid reliability risks as PG&E deenergizes lines during high winds. Mandated solar and wind displace dispatchable natural gas, straining ISO load balancing, transmission maintenance, and battery storage planning amid escalating wildfire liability.

 

Key Points

California grid shutoffs stem from wildfire risk, renewables, and deferred transmission maintenance under mandates.

✅ PG&E deenergizes lines to reduce wildfire ignition during high winds.

✅ Mandated solar and wind displace dispatchable gas, raising balancing costs.

✅ Storage, reliability pricing, and grid upgrades are needed to stabilize supply.

 

California is again facing widespread blackouts this season. Politicians are scrambling to assign blame to Pacific Gas & Electric (PG&E) a heavily regulated utility that can only do what the politically appointed regulators say it can do. In recent years this has meant building a bunch of solar and wind projects, while decommissioning reliable sources of power and scrimping on power line maintenance and upgrades.

The blackouts are connected with the legal liability from old and improperly maintained power lines being blamed for sparking fires—in hopes that deenergizing the grid during high winds reduces the likelihood of fires. 

How did the land of Silicon Valley and Hollywood come to have developing world electricity?

California’s Democratic majority, from Gov. Gavin Newsom to the solidly progressive legislature, to the regulators they appoint, have demanded huge increases in renewable energy. Renewable electricity targets have been pushed up, and policymakers are weighing a revamp of electricity rates to clean the grid, with the state expected to reach a goal of 33% of its power from renewable sources, mostly solar and wind, by next year, and 60% of its electricity from renewables by 2030.

In 2018, 31% of the electricity Californians purchased at the retail level came from approved renewables. But when rooftop solar is added to the mix, about 34% of California’s electricity came from renewables in 2018. Solar photovoltaic (PV) systems installed “behind-the-meter” (BTM) displace utility-supplied generation, but still affect the grid at large, as electricity must be generated at the moment it is consumed. PV installations in California grew 20% from 2017 to 2018, benefiting from the state’s Self-Generation Incentive Program that offers hefty rebates through 2025, as well as a 30% federal tax credit.

Increasingly large amounts of periodic, renewable power comes at a price—the more there is, the more difficult it is to keep the power grid stable and energized. Since electricity must be consumed the instant it is generated, and because wind and solar produce what they will whenever they do, the rest of the grid’s power producers—mostly natural gas plants—have to make up any differences between supply and immediate demand. This load balancing is vital, because without it, the grid will crash and widespread blackouts will ensue.

California often produces a surplus of mandated solar and wind power, generated for 5 to 8 cents per kilowatt hour. This power displaces dispatchable power from natural gas, coal and nuclear plants, resulting in reliable power plants spending less time online and driving up electricity prices as the plants operate for fewer hours of the day. Subsidized and mandated solar power, along with a law passed in California in 2006 (SB 1638) that bans the renewal of coal-fired power contracts, has placed enormous economic pressure on the Western region’s coal power plants—among them, the nation’s largest, Navajo Generating Station. As these plants go off line, the Western power grid will become increasingly unstable. Eventually, the states that share their electric power in the Western Interconnect may have to act to either subsidize dispatchable power or place a value on reliability—something that was taken for granted in the growth of the America’s electrical system and its regulatory scheme.

California law regarding electricity explicitly states that “a violation of the Public Utilities Act is a crime” and that it is “…the intent of the Legislature to provide for the evolution of the ISO (California’s Independent System Operator—the entity that manages California’s grid) into a regional organization to promote the development of regional electricity transmission markets in the western states.” In other words, California expects to dictate how the Western grid operates.

One last note as to what drives much of California’s energy policy: politics. California State Senator Kevin de León (the author served with him in the State Assembly) drafted SB 350, the Clean Energy and Pollution Reduction Act. It became law in 2015. Sen. de León followed up with SB 100 in 2018, signed into law weeks before the 2018 election. SB 100 increased California’s renewable portfolio standard to 60% by 2030 and further requires all the state’s electricity to come from carbon-free sources by 2045, a capstone of the state’s climate policies that factor into the blackout debate.  

Sen. de León used his environmental credentials to burnish his run for the U.S. Senate against Sen. Dianne Feinstein, eventually capturing the endorsements of the California Democratic Party and billionaire environmentalist Tom Steyer, now running for president. Feinstein and de León advanced to the general in California’s jungle primary, where Feinstein won reelection 54.2% to 45.8%.

De León may have lost his race for the U.S. Senate, but his legacy will live on in increasingly unaffordable electricity and blackouts, not only in California, but in the rest of the Western United States—unless federal or state regulators begin to place a value on reliability. This could be done by requiring utility scale renewable power providers to guarantee dispatchable power, as policymakers try to avert a looming shortage of firm capacity, either through purchase agreements with thermal power plants or through the installation of giant and costly battery farms or other energy storage means.

How vehicle-to-building charging can save costs, reduce GHGs and help balance the grid: study

Ontario EV Battery Storage ROI leverages V2B, V2G, two-way charging, demand response, and second-life batteries to monetize peak pricing, cut GHG emissions, and unlock up to $38,000 in lifetime value for commuters and buildings.

 

Key Points

The economic return from V2B/V2G two-way charging and second-life storage using EV batteries within Ontario's grid.

✅ Monetize peak pricing via workplace V2B discharging

✅ Earn up to $8,400 per EV over vehicle life

✅ Reduce gas generation and GHGs with demand response

 

The payback that usually comes to mind when people buy an electric vehicle is to drive an emissions-free, low-maintenance, better-performing mode of transportation.

On top of that, you can now add $38,000.

That, according to a new report from Ontario electric vehicle education and advocacy nonprofit, Plug‘n Drive, is the potential lifetime return for an electric car driven as a commuter vehicle while also being used as an electricity storage option amid an energy storage crunch in Ontario’s electricity system.

“EVs contain large batteries that store electric energy,” says the report. “Besides driving the car, [those] batteries have two other potentially useful applications: mobile storage via vehicle-to-grid while they are installed in the vehicle, and second-life storage after the vehicle batteries are retired.”

Pricing and demand differentials
The study, prepared by the research firm Strategic Policy Economics, modeled a two-stage scenario calculating the total benefits from both mobile and second-life storage when taking advantage of differences in daytime and nighttime electricity pricing and demand.


If done systematically and at scale, the combined benefits to EV owners, building operators and the electricity system in Ontario could reach $129 million per year by 2035, according to the report. Along with the financial gains, the province would also cut GHG emissions by up to 67.2 kilotons annually.

The math might sound complicated, but the concepts are simple. All it requires is for drivers to charge their batteries with low-cost electricity overnight at home, then plug them into two-way EV charging stations at work and discharge their stored electricity for use by the building by day when buying power from the grid is more expensive.

“Workplace buildings could avoid high daytime prices by purchasing electricity from EVs parked onsite and enjoy savings as a result,” says the report.

Based on average commuting distances, EVs in this scenario could make half their storage capacity available for discharge. Drivers would be paid out of the building’s savings, effectively selling electricity back to the grid and earning up to $8,400 over the life of their vehicle.

According to the report, Ontario could have as many as 18,555 vehicles participating in mobile storage by 2030. At this level, the daily electricity demand would be reduced by 565 MWh. This, in turn, would reduce demand for natural gas-fired electricity generation, a fossil-fuel electricity source, avoiding the expense of gas purchases while reducing GHG emissions.

The second-life storage opportunity begins when the vehicle lifespan ends. “EV batteries will still have over 80% of their storage capacity after being driven for 13 years and providing mobile storage,” the report states. “Those-second life batteries could provide a low-cost energy storage solution for the electricity grid and enhance grid stability over time.”

Some of the savings could be shared with EV owners in the form of a rebate worth up to 20 per cent of the batteries’ initial cost.

Call to action
The report concludes with a call to action for EV advocates to press policy makers and other stakeholders to take actions on building codes, the federal Clean Fuel Standard and other business models in order to maximize the benefits of using EV batteries for the electricity system in this way, even as growing adoption could challenge power grids in some regions.

“EVs are often approached as an environmental solution to climate change,” says Cara Clairman, Plug’n Drive president and CEO. “While this is true, there are significant economic opportunities that are often overlooked.”

Iran, Iraq Discuss Further Cooperation in Energy Sector

Iran-Iraq Electricity Cooperation advances with power grid synchronization, cross-border energy trade, 400-kV transmission lines, and education partnerships, boosting grid reliability, infrastructure investment, and electricity exports between Tehran and Baghdad for improved supply and stability.

 

Key Points

A bilateral initiative to synchronize grids, expand networks, and sustain electricity exports, improving reliability.

✅ 400-kV Amarah-Karkheh line enables synchronized operations.

✅ Extends electricity export contracts to meet Iraq demand.

✅ Enhances grid reliability, training, and infrastructure investment.

 

Aradakanian has focused his one-day visit to Iraq on discussions pertaining to promoting bilateral collaboration between the two neighboring nations in the field of electricity, grid development deals and synchronizing power grid between Tehran and Baghdad, cooperating in education, and expansion of power networks.

He is also scheduled to meet with Iraqi top officials in a bid to boost cooperation in the relevant fields.

Back in December 2019, Ardakanian announced that Iran will continue exports of electricity to Iraq by renewing earlier contract as it is supplying about 40% of Iraq's power today.

"Iran has signed a 3-year-long cooperation agreement with Iraq to help the country's power industry in different aspects. The documents states at its end that we will export electricity to Iraq as far as they need," Ardakanian told FNA on December 9, 2019.

The contract to "export Iran's electricity" to Iraq will be extended, he added.

Ardakanian also said that Iran and Iraq's power grids have become synchronized in a move that supports Iran's regional power hub plans since a month ago.

In 2004 Iran started selling electricity to Iraq. Iran electricity exports to the western neighbor are at its highest level of 1,361 megawatts per day now, as the country weighs summer power sufficiency ahead of peak demand.

The new Amarah-Karkheh 400-KV transmission line stretching over 73 kilometers, is now synchronized to provide electricity to both countries, reflecting regional power export trends as well. It also paves the way for increasing export to power-hungry Iraq in the near future.

With synchronization of the two grids, the quality of electricity in Iraq will improve as the country explores nuclear power options to tackle shortages.

According to official data, 82% of Iraq's electricity is generated by thermal power plants that use gas as feedstock, while Iran is converting thermal plants to combined cycle to save energy. This is expected to reach 84% by 2027.
