Enel, EDF move ahead on Italian nuclear projects

US Nuclear Generating Costs 2017 show USD33.50/MWh for nuclear energy, the lowest since 2008, as capital expenditures, fuel costs, and operating costs declined after license renewals and uprates, supporting a reliable, low-carbon grid.

Key Points

The 2017 US nuclear average was USD33.50/MWh, lowest since 2008, driven by reduced capital, fuel, and operating costs.

✅ Average cost USD33.50/MWh, lowest since 2008

✅ Capital, fuel, O&M costs fell sharply since 2012 peak

✅ License renewals, uprates, market reforms shape competitiveness

Average total generating costs for nuclear energy in 2017 in the USA were at their lowest since 2008, according to a study released by the Nuclear Energy Institute (NEI), amid a continuing nuclear decline debate in other regions.

The report, Nuclear Costs in Context, found that in 2017 the average total generating cost - which includes capital, fuel and operating costs - for nuclear energy was USD33.50 per megawatt-hour (MWh), even as interest in next-generation nuclear designs grows among stakeholders. This is 3.3% lower than in 2016 and more than 19% below 2012's peak. The reduction in costs since 2012 is due to a 40.8% reduction in capital expenditures, a 17.2% reduction in fuel costs and an 8.7% reduction in operating costs, the organisation said.

The year-on-year decline in capital costs over the past five years reflects the completion by most plants of efforts to prepare for operation beyond their initial 40-year licence. A few major items - a series of vessel head replacements; steam generator replacements and other upgrades as companies prepared for continued operation, and power uprates to increase output from existing plants - caused capital investment to increase to a peak in 2012. "As a result of these investments, 86 of the [USA's] 99 operating reactors in 2017 have received 20-year licence renewals and 92 of the operating reactors have been approved for uprates that have added over 7900 megawatts of electricity capacity. Capital spending on uprates and items necessary for operation beyond 40 years has moderated as most plants are completing these efforts," it says.

Since 2013, seven US nuclear reactors have shut down permanently, with the Three Mile Island debate highlighting wider policy questions, and another 12 have announced their permanent shutdown. The early closure for economic reasons of reliable nuclear plants with high capacity factors and relatively low generating costs will have long-term economic consequences, the report warns: replacement generating capacity, when needed, will produce more costly electricity, fewer jobs that will pay less, and, for net-zero emissions objectives, more pollution, it says.

NEI Vice President of Policy Development and Public Affairs John Kotek said the "hardworking men and women of the nuclear industry" had done an "amazing job" reducing costs through the institute's Delivering the Nuclear Promise campaign and other initiatives, in line with IAEA low-carbon lessons from the pandemic. "As we continue to face economic headwinds in markets which do not properly compensate nuclear plants, the industry has been doing its part to reduce costs to remain competitive," he said.

"Some things are in urgent need of change if we are to keep the nation's nuclear plants running and enjoy their contribution to a reliable, resilient and low-carbon grid. Namely, we need to put in place market reforms that fairly compensate nuclear similar to those already in place in New York, Illinois and other states," Kotek added.

Cost information in the study was collected by the Electric Utility Cost Group with prior years converted to 2017 dollars for accurate historical comparison.

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

Lebanon-ENOC Fuel Swap secures Iraqi high sulphur fuel oil, Grade B fuel oil, and gasoil via tender, easing electricity generation shortfalls, diesel shortages, and grid outages amid Lebanon's energy crisis and power sector emergency.

Key Points

A tender-based exchange trading Iraqi HSFO for cleaner fuel oil and gasoil to stabilize Lebanon's electricity generation.

✅ Swaps 84,000t Iraqi HSFO for 30,000t Grade B fuel oil and 33,000t gasoil

✅ Supports state electricity generation during acute power shortages

✅ Tender won by ENOC under Lebanon-Iraq goods-for-fuel deal

Lebanon's energy ministry said it had picked Dubai's ENOC in a tender to swap 84,000 tonnes of Iraqi high sulphur fuel oil, as LNG export authorizations expand globally, with 30,000 tonnes of Grade B fuel oil and 33,000 tonnes of gasoil.

ENOC won the tender, part of a deal between the two countries that allows the cash-strapped Lebanese government, even as electricity tensions persist, to pay for 1 million tonnes of Iraqi heavy fuel oil a year in goods and services.

As Lebanon suffers what the World Bank has described as one of the deepest depressions of modern history, shortages of fuel this month have meant state-powered electricity, alongside ongoing electricity sector reform, has been available for barely a few hours a day if at all.

Residents turning to private generators for their power supply face diesel shortages, even as other countries roll out measures to secure electricity supplies to mitigate risks.

The swap tenders are essential as Iraqi fuel is unsuitable for Lebanese electricity generation, and regional projects like the Jordan-Saudi electricity linkage underscore broader grid strategies.

Lebanese caretaker Energy Minister Raymond Ghajar said in July the fuel from the Iraqi deal would be used for electricity generation by the state provider, even as France advances a new electricity pricing scheme in Europe, and was enough for around four months.

ENOC is set to receive the Iraq fuel between Sept. 3-5 and will deliver it to Lebanon two weeks after, the energy ministry said, following a recent deal on electricity prices abroad that could influence markets.

Denmark 2019 electricity CO2 intensity shows record-low emissions as renewable energy surges, wind power dominates, offshore wind expands, and coal phase-out accelerates Denmark's energy transition and grid decarbonization, driven by higher CO2 prices and flexibility.

Key Points

It is 135 g CO2/kWh, a record low enabled by wind power growth, offshore wind, and a sharp coal decline.

✅ Average emissions fell to 135 g CO2/kWh, the lowest on record

✅ Wind and solar supplied 49.9% of national electricity use

✅ Coal consumption dropped 46% as CO2 allowance prices rose

Danish electricity producers set a new green record in 2019, when an average produced kilowatt-hour emitted 135 gr CO2 / kWh.

It is the lowest CO2 emission ever measured in Denmark and about one-seventh of what the electricity producers emitted in 1990.

Never has a kilowatt-hour produced emitted as little CO2 as it did in 2019. And that's according to Energinet's recently published annual Environmental Report on Danish electricity generation and cogeneration, two primary causes.

One reason is that more green power has been produced because the Horns Rev 3 offshore wind farm, which can produce electricity for 425,000 households, was commissioned in 2019. The other is that Danish coal consumption fell by 46 percent from 2018 to 2019, as coal phase-out plans gathered pace across the sector. the dramatic decline in coal consumption is partly due a significant increase in the price of CO2 quotas, and thus also the price of CO2 emissions.

'Historically, 135 gr CO2 / kWh is a really, really low figure, showing the impressive green travel that the Danish electricity system has been on. In 1990, a kilowatt-hour produced emitted over 1000 grams of CO2, ie about seven times as much as today, 'says Hanne Storm Edlefsen, area manager in Energinet Power Systems Responsibility.

Wind energy is the dominant form of electricity generation in Denmark, a pattern the UK wind beat coal in 2016 when shifting away from fossil fuels.

17.1 TWh. Danish wind turbines and solar cells generated so much electricity in 2019, corresponding to 49.9 per cent. of Danish electricity consumption, reflecting broader EU wind and solar growth trends as well. An increase of 15 per cent. The wind turbines alone produced 16 TWh, which is not only a new green record, but also puts a thick line that wind energy is by far the most dominant form of electricity generation in Denmark.

'Thanks to our large wind resources, turbines are by far the largest supplier of renewable energy in Denmark, and this will be for many years to come. The large price drop in new wind energy in recent years - for both onshore and offshore winds - will ensure that wind energy will drive a large part of the growth in renewable energy in the coming years, as new wind generation records are set in markets like the UK, 'says Soren Klinge, electricity market manager at Wind Denmark.

Conversely, total electricity generation from fossil and bio-based fuels decreased by 26 PJ (petajoule ed.), Corresponding to 34 per cent. from 2018 to 2019, mirroring renewables overtaking coal in Germany. Nevertheless, net electricity generation was just under 30 TWh both years.

'It is worth noting that while fossil fuels are being phased out, Denmark maintains its annual net production of electricity. The green, so to speak, replaces the black. It once again underpins that green conversion, high security of supply and an affordable electricity price can go hand in hand, 'says Hanne Storm Edlefsen.

Danish power system is ready for a green future

Including trade in electricity with neighboring countries, 1 kWh in a Danish outlet generates 145 gr CO2 / kWh.

'There has been a very significant development in the Danish electricity system in recent years, where the electricity system can now be operated solely on the renewable energy. It is a remarkable development, also from an international perspective where low-carbon progress stalled in the UK in 2019, that one would not have thought possible for just a few years ago, 'he says.

More than expected have phased out coal

The electricity from the Danish sockets will be greener , predicts Energinet's environmental report , which expects CO2 intensity in the coming years. This is explained by an expectation of increased electrification of energy consumption, together with a continued expansion with wind and solar.

'Wind energy is the cornerstone of the green transition. With the commissioning of the Kriegers Flak offshore wind farm and several major onshore wind turbine projects within the next few years, we can well expect that only the wind's share of electricity consumption will exceed 50 per cent hopefully as early as 2021,' concludes Soren Klinge.

Miami Valley Windstorm Power Outages disrupted thousands as 60 mph gusts toppled trees, downed power lines, and damaged buildings. Utility crews and emergency services managed debris, while NWS alerts warned of extended restoration.

Key Points

Region-wide power losses from severe winds in the Miami Valley, causing damage, debris, and restoration.

✅ 60 mph gusts downed trees, snapped lines, blocked roads

✅ Crews from DP&L worked extended shifts to restore service

✅ NWS issued wind advisories; schools, businesses closed

On a recent day, powerful winds tore through the Miami Valley, causing significant disruption across the region. The storm, which was accompanied by gusts reaching dangerous speeds, led to windstorm power outages affecting thousands of homes and businesses. As trees fell and power lines were snapped, many residents found themselves without electricity for hours, and in some cases, even days.

The high winds, which were part of a larger weather system moving through the area, left a trail of destruction in their wake. In addition to power outages, there were reports of storm damage to buildings, vehicles, and other structures. The force of the wind uprooted trees, some of which fell on homes and vehicles, causing significant property damage. While the storm did not result in any fatalities, the destruction was widespread, with many communities experiencing debris-filled streets and blocked roads.

Utility companies in the Miami Valley, including Dayton Power & Light, quickly mobilized crews, similar to FPL's storm response in major events, to begin restoring power to the affected areas. However, the high winds presented a challenge for repair crews, as downed power lines and damaged equipment made restoration efforts more difficult. Many customers were left waiting for hours or even days for their power to be restored, and some neighborhoods were still experiencing outages several days after the storm had passed.

In response to the severe weather, local authorities issued warnings to residents, urging them to stay indoors and avoid unnecessary travel. Wind gusts of up to 60 miles per hour were reported, making driving hazardous, particularly on bridges and overpasses, similar to Quebec windstorm outages elsewhere. The National Weather Service also warned of the potential for further storm activity, advising people to remain vigilant as the system moved eastward.

The impact of the storm was felt not only in terms of power outages but also in the strain it placed on emergency services. With trees blocking roads and debris scattered across the area, first responders were required to work quickly and efficiently to clear paths and assist those in need. Many residents were left without heat, refrigeration, and in some cases, access to medical equipment that relied on electricity.

Local schools and businesses were also affected by the storm. Many schools had to cancel classes, either due to power outages or because roads were impassable. Businesses, particularly those in the retail and service sectors, faced disruptions in their operations as they struggled to stay open without power amid extended outages that lingered, or to address damage caused by fallen trees and debris.

In the aftermath of the storm, Miami Valley residents are working to clean up and assess the damage. Many homeowners are left dealing with the aftermath of tree removal, property repairs, and other challenges. Meanwhile, local governments are focusing on restoring infrastructure, as seen after Toronto's spring storm outages in recent years, and ensuring that the power grid is secured to prevent further outages.

While the winds have died down and conditions have improved, the storm’s impact will be felt for weeks to come, reflecting Florida's weeks-long restorations after severe storms. The region will continue to recover from the damage, but the event serves as a reminder of the power of nature and the resilience of communities in the face of adversity. For residents affected by the power outages, recovery will require patience as utility crews and local authorities work tirelessly to restore normalcy.

Looking ahead, experts are urging residents to prepare for the next storm season by ensuring that they have emergency kits, backup generators, and contingency plans in place. As climate change contributes to more extreme weather events, it is likely that storms of this magnitude will become more frequent. By taking steps to prepare in advance, communities across the Miami Valley can better handle whatever challenges come next.

Nova Scotia Integrated Resource Plan evaluates NSPI supply options, UARB oversight, Muskrat Falls imports, coal retirements, wind and biomass expansion, transmission upgrades, storage, and least-cost pathways to decarbonize the grid for ratepayers.

Key Points

A 25-year roadmap assessing supply, imports, costs, and emissions to guide least-cost decarbonization for Nova Scotia.

✅ Compares wind, biomass, gas, imports, and storage costs

✅ Addresses coal retirements, emissions caps, and reliability

✅ Recommends transmission upgrades and Muskrat Falls utilization

Maintaining a viable electricity network requires good long-term planning and, as a recent grid operations report notes, ongoing operational improvements. The existing stock of generating assets can become obsolete through aging, changes in fuel prices or environmental considerations. Future changes in demand must be anticipated.

Periodically, an integrated resource plan is created to predict how all this will add up during the ensuing 25 years. That process is currently underway and is led by Nova Scotia Power Inc. (NSPI) and will be submitted for approval to the Utilities and Review Board (UARB).

Coal-fired plants are still the largest single source of electricity in Nova Scotia. They need to be replaced with more environmentally friendly sources when they reach the end of their useful lives. Other sources include wind, hydroelectricity from rivers, biomass, as seen in increased biomass use by NS Power, natural gas and imports from other jurisdictions.

Imports are used sparingly today but will be an important source when the electricity from Muskrat Falls comes on stream. That project has big capacity. It can produce all the power needed in Newfoundland and Labrador (NL), where Quebec's power ambitions influence regional flows, plus the amount already committed to Nova Scotia, and still have a lot left over.

Some sources of electricity are more valuable than others. The daily amount of power from wind and solar cannot be controlled. Fuel-based sources and hydro can.

Utilities make their profits by providing the capital necessary to build infrastructure. Most of the money is borrowed but a portion, typically 30 per cent, usually comes from NSPI or a sister company. On that they receive a rate of return of nine per cent. Nova Scotia can borrow money today at less than two per cent.

The largest single investment of that type is the $1.577-billion Maritime Link connecting power from Newfoundland to Nova Scotia. It continues through to the New Brunswick border to facilitate exports to the United States. NSPI’s sister company, NSP Maritime Link Inc. (NSPML), is making nine per cent on $473 million of the cost.

There is little unexploited hydro capacity in Nova Scotia and there will not be any new coal-fired plants. Large-scale solar is not competitive in Nova Scotia’s climate. Nova Scotia’s needs would not accommodate the amount of nuclear capacity needed to be cost-effective, even as New Brunswick explores small reactors in its strategy.

So the candidates for future generating resources are wind, natural gas, biomass (though biomass criticism remains) and imports from other jurisdictions. Tidal is a promising opportunity but is still searching for a commercially viable technology. 

NSPI is commendably transparent about its process (irp.nspower.ca). At this stage there is little indication of the conclusions they are reaching but that will presumably appear in due course.

The mountains of detail might obscure the fact that NSPI is not an unbiased arbiter of choices for the future.

It is reported that they want to prematurely close the Trenton 5 coal plant in 2023-25. It is valued at $88.5 million. If it is closed early, ratepayers will still have to pay off the remaining value even though the plant will be idle. NSPI wants to plan a decommissioning of five of its other seven plants. There is a federal emissions constraint but retiring coal plants earlier than needed will cost ratepayers a lot.

Whenever those plants are closed, there will be a need for new sources of power. NSPI is proposing to plan for new investments in new transmission infrastructure to facilitate imports. Other possibilities would be additional wind farms, consistent with the shift to more wind and solar projects, thermal plants that burn natural gas or biomass, or storage for excess wind power that arrives before it can be used. The investment in storage could be anywhere from $20 million to $200 million.

These will add to the asset burden funded by ratepayers, even as industrial customers seek discounts while still paying for shuttered coal infrastructure.

External sources of new power will not provide NSPI the same opportunity: wind power by independent producers might be less expensive because they are willing to settle for less than nine per cent or because they are more efficient. Buying more power from Muskrat Falls will use transmission infrastructure we are already paying for. If a successful tidal technology is found, it will not be owned by NSPI or a sister company, which are no longer trying to perfect the technology.

This is not to suggest that NSPI would misrepresent the alternatives. But they can tilt the discussion in their favour. How tough will they be negotiating for additional Muskrat Falls power when it hurts their profits? Arguing for premature coal retirement on environmental grounds is fair game but whether the cost should be accepted is a political choice. 

NSPI is in a conflict of interest. We need a different process. An independent body should author the integrated resource plan. They should be fully informed about NSPI’s views.

They should communicate directly with Newfoundland and Labrador for Muskrat power, with independent wind producers, and with tidal power companies. The UARB cannot do any of these things.

The resulting plan should undergo the same UARB review that NSPI’s version would. This enhances the likelihood that Nova Scotians will get the least-cost alternative.
