American Transmission Co.Â’s $1.7 billion investment in reliability and efficiency upgrades to the transmission grid over the past seven years also has contributed to energy savings and reduced carbon emissions.

ATC demonstrates in recently released figures that its more robust high-voltage transmission system has helped reduce electrical output at peak times equivalent to a 125-megawatt generating plant.

“Our investment may be one of the largest energy savings programs in the Upper Midwest,” said José Delgado, ATC president and chief executive officer. “The more efficient high-voltage lines and newer infrastructure that we’ve placed in service results in lower line losses. We can translate this into significant environmental benefits. With the recent approval of the final report by Wisconsin Governor Jim Doyle’s Task Force on Global Warming, this is good news.”

Flora Flygt, director of ATC Transmission Planning, explained, “Transmission system improvements also function as major energy efficiency upgrades on the electric system because of the sheer volume of energy they carry. Even a small increase in the efficiency of the grid’s power-carrying capabilities can yield significant energy-saving and carbon-reducing results.”

She said the savings are due to reduced electricity losses. “In simple terms, our improvements mean that the wires do not get as hot, which results in substantially lower electricity losses in the process of moving power into communities,” said Flygt.

Lower losses between the generation source and the delivery point mean a reduction in the required electricity output needed to transport power and meet demand. If the generation source is a fossil-fueled power plant, the result is lower carbon emissions. Losses on ATCÂ’s high-voltage network are relatively low at around 2.2 percent of energy carried.

ATCÂ’s energy savings calculation compares the companyÂ’s system as it was in summer 2001 with the improved system in place by summer 2007. The reduced losses over the 40-year life of these projects equate to:

• 16.2 million megawatt hours of electricity saved (enough to power 38,000 homes each year).

• 15 million tons of CO2 emissions associated with producing lost energy are eliminated.

• The equivalent of a 125-megawatt generating plant not having to be built to serve peak demand.

The figures above do not include the savings from the 220-mile Arrowhead-Weston 345-kilovolt transmission line, which ATC placed in service in January 2008. The reduction of losses associated with the Arrowhead-Weston transmission line is estimated at roughly 24 megawatts of on-peak usage.

ATCÂ’s program of rebuilding and up-rating existing transmission lines and constructing new ones results in power being carried more efficiently than it would be over the older, lower-voltage grid in three ways:

• Rebuilding existing power lines using a larger conductor enhances efficiency. The larger conductor reduces the resistance of the lines, which reduces losses.

• Adding new transmission lines to an overloaded system divides power flows over multiple paths, which reduces electric current and losses on each individual power line.

• Installing higher voltage lines allows demand to be met with lower levels of current and lower line resistance, which also reduces losses.

On the transmission system, extra-high voltage lines typically provide the greatest potential for energy loss reduction. ATC expects to add four additional 345-kilovolt transmission lines in the next five years, which will reduce losses even further:

• Gardner Park – Central Wisconsin is a 50-mile project in Central Wisconsin scheduled to be energized in spring 2009.

• Morgan - Werner West is a 50-mile project in Central Wisconsin scheduled to be energized in spring 2009.

• Paddock - Rockdale is a 35-mile project in Southern Wisconsin expected to be on line in April 2010.

• Rockdale - West Middleton is a 35-55 mile proposed project in South Central Wisconsin slated to be in service in spring 2013.

Duke solar solicitation nearly 6x over-subscribed

Duke Energy Carolinas Solar RFP draws 3.9 GW of utility-scale bids, oversubscribed in DEP and DEC, below avoided cost rates, minimal battery storage, strict PPA terms, and interconnection challenges across North and South Carolina.

 

Key Points

Utility-scale solar procurement in DEC and DEP, evaluated against avoided cost, with few storage bids and PPA terms.

✅ 3.9 GW bids for 680 MW; DEP most oversubscribed

✅ Most projects 7-80 MWac; few include battery storage

✅ Bids must price below 20-year avoided cost estimate

 

Last week the independent administrator for Duke’s 680 MW solar solicitation revealed data about the projects which have bid in response to the offer, showing a massive amount of interest in the opportunity.

Overall, 18 individuals submitted bids for projects in Duke Energy Carolinas (DEC) territory and 10 in Duke Energy Progress (DEP), with a total of more than 3.9 GW of proposals – more nearly 6x the available volume. DEP was relatively more over-subscribed, with 1.2 GWac of projects vying for only 80 MW of available capacity.

This is despite a requirement that such projects come in below the estimate of Duke’s avoided cost for the next 20 years, and amid changes in solar compensation that could affect project economics. Individual projects varied in capacity from 7-80 MWac, with most coming within the upper portion of that range.

These bids will be evaluated in the spring of 2019, and as Duke Energy Renewables continues to expand its portfolio, Duke Energy Communications Manager Randy Wheeless says he expects the plants to come online in a year or two.

 

Lack of storage

Despite recent trends in affordable batteries, of the 78 bids that came in only four included integrated battery storage. Tyler Norris, Cypress Creek Renewables’ market lead for North Carolina, says that this reflects that the methodology used is not properly valuing storage.

“The lack of storage in these bids is a missed opportunity for the state, and it reflects a poorly designed avoided cost rate structure that improperly values storage resources, commercially unreasonable PPA provisions, and unfavorable interconnection treatment toward independent storage,” Norris told pv magazine.

“We’re hopeful that these issues will be addressed in the second RFP tranche and in the current regulatory proceedings on avoided cost and state interconnection standards and grid upgrades across the region.”

 

Limited volume for North Carolina?

Another curious feature of the bids is that nearly the same volume of solar has been proposed for South Carolina as North Carolina – despite this solicitation being in response to a North Carolina law and ongoing legal disputes such as a church solar case that challenged the state’s monopoly model.

Annual U.S. coal-fired electricity generation will increase for the first time since 2014

U.S. coal-fired generation 2021 rose as higher natural gas prices, stable coal costs, and a recovering power sector shifted the generation mix; capacity factors rebounded despite low coal stocks and ongoing plant retirements.

 

Key Points

Coal output rose 22% on high gas prices and higher capacity factors; a 5% decline is expected in 2022.

✅ Natural gas delivered cost averaged $4.93/MMBtu, more than double 2020

✅ Coal capacity factor rose to ~51% from 40% in 2020

✅ 2022 coal generation forecast to fall about 5%

 

We expect 22% more U.S. coal-fired generation in 2021 than in 2020, according to our latest Short-Term Energy Outlook (STEO). The U.S. electric power sector has been generating more electricity from coal-fired power plants this year as a result of significantly higher natural gas prices and relatively stable coal prices, even as non-fossil sources reached 40% of total generation. This year, 2021, will yield the first year-over-year increase in coal generation in the United States since 2014, highlighted by a January power generation jump earlier in the year.

Coal and natural gas have been the two largest sources of electricity generation in the United States. In many areas of the country, these two fuels compete to supply electricity based on their relative costs and sensitivity to policies and gas prices as well. U.S. natural gas prices have been more volatile than coal prices, so the cost of natural gas often determines the relative share of generation provided by natural gas and coal.

Because natural gas-fired power plants convert fuel to electricity more efficiently than coal-fired plants, record natural gas generation has at times underscored that advantage, and natural gas-fired generation can have an economic advantage even if natural gas prices are slightly higher than coal prices. Between 2015 and 2020, the cost of natural gas delivered to electric generators remained relatively low and stable. This year, however, natural gas prices have been much higher than in recent years. The year-to-date delivered cost of natural gas to U.S. power plants has averaged $4.93 per million British thermal units (Btu), more than double last year’s price.

The overall decline in electricity demand in 2020 and record-low natural gas prices led coal plants to significantly reduce the percentage of time that they generated power. In 2020, the utilization rate (known as the capacity factor) of U.S. coal-fired generators averaged 40%. Before 2010, coal capacity factors routinely averaged 70% or more. This year’s higher natural gas prices have increased the average coal capacity factor to about 51%, which is almost the 2018 average, a year when wind and solar reached 10% nationally.

Although rising natural gas prices have resulted in more U.S. coal-fired generation than last year, this increase in coal generation will most likely not continue as solar and wind expand in the generation mix. The electric power sector has retired about 30% of its generating capacity at coal plants since 2010, and no new coal-fired capacity has come online in the United States since 2013. In addition, coal stocks at U.S. power plants are relatively low, and production at operating coal mines has not been increasing as rapidly as the recent increase in coal demand. For 2022, we forecast that U.S. coal-fired generation will decline about 5% in response to continuing retirements of generating capacity at coal power plants and slightly lower natural gas prices.

Canada Invests Over $960-Million in Renewable Energy and Grid Modernization Projects

Smart Renewables and Electrification Pathways Program enables clean energy and grid modernization across Canada, funding wind, solar, hydro, geothermal, tidal, and storage to cut GHG emissions and accelerate electrification toward a net-zero economy.

 

Key Points

A $964M Canadian program funding clean power and grid upgrades to cut emissions and build net-zero electrified economy.

✅ Funds wind, solar, hydro, geothermal, tidal, and storage projects

✅ Modernizes grids for reliability, digitalization, and resilience

✅ Supports net-zero by 2050 with Indigenous and utility partners

 

Harnessing Canada's immense clean energy resources requires transformational investments to modernize our electricity grid. The Government of Canada is investing in renewable energy and upgrading the electricity grid, moving toward an electric, connected and clean economy, to make clean, affordable electricity options more accessible in communities across Canada.

The Honourable Seamus O'Regan Jr., Minister of Natural Resources, today launched a $964-million program, alongside a recent federal green electricity contract in Alberta that underscores momentum, to support smart renewable energy and grid modernization projects that will lower emissions by investing in clean energy technologies, like wind, solar, storage, hydro, geothermal and tidal energy across Atlantic Canada.

The Smart Renewables and Electrification Pathways Program (SREPs) supports building Canada's low-emissions energy future and a renewable, electrified economy through projects that focus on non-emitting, cleaner energy technologies, such as storage, and modernizing electricity system operations.

Investing in these technologies reduces greenhouse gas emissions by creating a cleaner, more connected electrical system, supporting progress toward zero-emissions electricity by 2035 goals, while helping Canada reach net-zero emissions by 2050.

Minister O'Regan launched the program during the Canadian Electricity Association's (CEA) virtual regulatory forum on Electricity Regulation & the Four Disruptors – Decarbonization, Decentralization, Digitalization and Democratization, highlighting evolving regulatory approaches as B.C. streamlines clean energy approvals to support deployment nationwide. The launch also coincides with Canadian Environment Week, which celebrates Canada's environmental accomplishments and encourages Canadians to contribute to conserving and protecting the environment.

Through SREPs and other programming, the government is working with provinces and territories, with the Prairie Provinces leading renewable growth in the years ahead, utilities, Indigenous partners and others, including diverse businesses and communities, to deliver these clean and reliable energy initiatives. With Canadian innovation, technology and skilled energy workers, we can provide more communities, households and businesses with an increased supply of clean electricity and a cleaner electrical grid.

To help interested stakeholders find information on SREPs, a new webpage has been launched, which includes a comprehensive guide for eligible projects.

This supports Canada's strengthened climate plan, A Healthy Environment and a Healthy Economy. Canada is advancing projects that support the clean grid of the future and seize opportunities in the global electricity market to boost competitiveness. Collectively with investments from the Fall Economic Statement 2020 and Budget 2021, Canada will achieve our climate change commitments and ensure a healthier environment and more prosperous economy for future generations.

A goodwill gesture over electricity sows discord in Lebanon

Lebanon Power Barge Controversy spotlights Karadeniz Energy's Esra Sultan, Lebanon's electricity crisis, prolonged blackouts, and sectarian politics as Amal and Hezbollah clash over Zahrani vs Jiyeh docking and allocation across regions.

 

Key Points

A political dispute over the Esra Sultan power ship, its docking, and power allocation amid Lebanon's chronic blackouts.

✅ Karadeniz Energy lent a third barge at below-market rates.

✅ Docking disputes: Zahrani refused; Jiyeh limited; Zouq connected.

✅ Amal vs Hezbollah split exposes sectarian energy politics.

 

It was supposed to be a goodwill gesture from an energy company in Turkey.

This summer, the Karadeniz Energy Group lent Lebanon a floating power station to generate electricity at below-market rates to help ease the strain on the country's woefully undermaintained power sector.

Instead, the barge's arrival opened a Pandora's box of partisan mudslinging in a country hobbled by political sectarianism and dysfunction.

There have been rows over where it should dock, how to allocate its 235 megawatts of power, and even what to call the barge, echoing controversies like the Maine electric line debate that pit local politics against energy needs.

It has even driven a wedge between Lebanon's two dominant parties among Shiite Muslims: Amal and the militant group Hezbollah.

Amal, which has held the parliament speaker's seat since 1992, revealed sensationally last week it had refused to allow the boat to dock in a port in the predominantly Shiite south, even though it is one of the most underserved regions of Lebanon.

Power outages in the south can stretch on for more than 12 hours a day, much like the Gaza electricity crisis, according to regional observers.

Hezbollah, which normally stands pat with Amal in political matters, issued an exceptional statement that it had nothing to do with the matter of the barge at Zahrani port. A Hezbollah lawmaker went further to say his party disagreed on the issue with Amal.

Ali Hassan Khalil, Lebanon's Finance Minister and a leading Amal party member, said southerners wanted a permanent power station, not a stop-gap solution, in an implied dig at the rival Free Patriotic Movement, a Christian party that runs the Energy Ministry.

But critics seized on the statement as confirmation that Amal's leaders were in bed with the operators of private generators, who have been making fortunes selling electricity during blackouts at many times the state price.

"For decades there's been nothing stopping them from building a power plant," said Mohammad Obeid, a former Amal party official, in an interview with Lebanon's Al Jadeed TV station.

"Now there's a barge that's coming for three months to provide a few more hours of electricity -- and that's the issue?"

Hassan Khalil, reached by phone, refused to comment.

Nabih Berri, Amal's chief and Lebanon's parliament speaker, who has long been the subject of critical coverage from Al Jadeed's, sued the TV channel for libel on Wednesday for its reporting.

Energy Minister Cesar Abi Khalil, a Christian, lashed out at Amal, saying the ministry even changed the barge's name from Ayse, Turkish for Aisha, a name associated in Lebanon with Sunnis, to Esra Sultan, which does not carry any Shiite or Sunni connotations, to try to get it to dock in Zahrani.

Karadeniz said the barge was renamed "out of courtesy and respect to local customs and sensitivities."

"Ayse is a very common Turkish name, where such preferences are not as sensitive as in Lebanon," it said in a statement to The Associated Press.

Finally, on July 18, the barge docked in Jiyeh, a harbour south of Beirut but north of Zahrani, and in a religiously mixed Muslim area.

But two weeks later it was unmoored again, after Abi Khalil, the energy minister, said the infrastructure at Jiyeh could only handle 30 megawatts of the Esra Sultan's 235 capacity, and upgrades such as burying subsea cables are expensive.

With Zahrani closed to the Esra Sultan, it could only go to Zouq Mikhael, a port in the Christian-dominated Kesrouan region in the north, where it was plugged to the grid Tuesday night, giving the region almost 24 hours of electricity a day.

Lebanon has been contending with rolling blackouts since the days of its 1975-1990 civil war. Successive governments have failed to agree on a permanent solution for the chronic electricity failures, largely because of profiteering, endemic corruption and lack of political will, despite periodic pushes for electricity sector reform in Lebanon over the years.

In 2013, the Energy Ministry contracted with Karadeniz to buy electricity from a pair of its barges, which are still docked in Jiyeh and Zouq Mikhael.

This summer, Abi Khalil signed a new contract with Karadeniz to keep the barges for another three years. As part of the deal, Karadeniz agreed to lend Lebanon the third barge, the Esra Sultan, to produce electricity for three months at no cost - Lebanon would just have to pay for the fuel.

The company said Lebanon's internal squabbles do not affect how long the Esra Sultan would stay in Lebanon, even amid wider sector volatility and the pandemic's impact highlighted in a recent financial update. It arrived on July 18 and it will leave on Oct. 18, it said.

Germany turns to coal for a third of its electricity

Germany's Coal Reliance reflects an energy crisis, soaring natural gas prices, and a nuclear phase-out, as Destatis data show higher coal-fired electricity despite growing wind and solar generation, impacting grid stability and emissions.

 

Key Points

Germany's coal reliance is more coal power due to gas spikes and a nuclear phase-out, despite wind and solar growth.

✅ Coal share near one-third of electricity, per Destatis

✅ Gas-fired output falls as prices soar after Russia's invasion

✅ Wind and solar rise; grid stability and recession risks persist

 

Germany is relying on highly-polluting coal for almost a third of its electricity, as the impact of government policies, reflecting an energy balancing act for the power sector, and the war in Ukraine leads producers in Europe’s largest economy to use less gas and nuclear energy.

In the first six months of the year, Germany generated 82.6 kWh of electricity from coal, up 17 per cent from the same period last year, according to data from Destatis, the national statistics office, published on Wednesday. The leap means almost one-third of German electricity generation now comes from coal-fired plants, up from 27 per cent last year. Production from natural gas, which has tripled in price to €235 per megawatt hour since Russia’s invasion in late February, fell 18 per cent to only 11.7 per cent of total generation.

Destatis said that the shift from gas to coal was sharper in the second quarter. Coal-fired electricity increased by an annual rate of 23 per cent in the three months to June, while electricity generation from natural gas fell 19 per cent.

The figures highlight the challenge facing European governments in meeting clean energy goals after the Kremlin announced this week that the Nordstream 1 pipeline that takes Russian gas to Germany would remain closed until Europe removed sanctions on the country’s oil.

Germany has been trying to reduce its reliance on coal, which releases almost twice as many emissions as gas and more than 60 times those of nuclear energy, according to estimates from the Intergovernmental Panel on Climate Change, though grid expansion challenges have slowed renewable build-out in recent years.

Chancellor Olaf Scholz said the opposition CDU bore “complete responsibility” for the exit from coal and nuclear power that formed part of his predecessor Angela Merkel’s Energiewende policies, amid a continuing nuclear option debate in climate policy, which in turn raised reliance on Russian gas. At the beginning of this year, more than 50 per cent of Germany’s gas imports came from Russia, a figure that fell slightly over the opening half of 2022.

But CDU leader Friedrich Merz accused the government of “madness” over its decision to idle the country’s three remaining nuclear power stations from the end of this year, though officials have argued that nuclear would do little to solve the gas issue in the short term.

Electricity generation from nuclear energy has already halved after three of the six nuclear power plants that were still in operation at the end of 2021 were closed during the first half of this year. Berlin said on Monday it would keep on standby two of its remaining three nuclear power stations, a move to extend nuclear power during the energy crisis, which were all due to close at the end of the year.

The German government has warned of the risk of electricity shortages this winter. “We cannot be sure that, in the event of grid bottlenecks in neighbouring countries, there will be enough power plants available to help stabilise our electricity grid in the short term,” said German economy minister Robert Habeck on Monday.

However Scholz said that, after raising gas storage levels to 86 per cent of capacity, Germany would “probably get through this winter, despite all the tension”.

One bright spot from the data was the increase in use of renewable energy, highlighting a recent renewables milestone in Germany. The proportion of electricity generated from wind power generation rose by 18 per cent to 25 per cent of all electricity generation, while solar energy production increased 20 per cent.

Ángel Talavera, head of Europe economics at the consultancy Oxford Economics, said that the success in moving away from gas towards other energy sources “means that the risks of hard energy rationing over the winter are less severe now, even with little to no Russian gas flows”.

However, economists still expect a recession in the eurozone’s largest economy, amid a deteriorating German economy outlook over the near term, as a large part of the impact comes via higher prices and because industries and households still rely on gas for heating.

Separate official data also published on Wednesday showed that German industrial production slid 0.3 per cent between June and July. Production at Germany’s most energy intensive industries fell almost 7 per cent in the five months after Russia’s invasion of Ukraine.

“The demand destruction caused by the surge in prices will still send the German economy into recession over the winter,” said Talavera.
