Duke Energy seeks changes in how solar owners are paid for electricity

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.

Scotland Wind Energy delivered record renewable power as wind turbines and farms generated 9,831,320 MWh in H1 2019, supplying clean electricity for every home twice and supporting northern England, according to WWF data.

Key Points

Term for Scotland's wind power output, highlighting 2019 records, clean electricity, and progress on decarbonization.

✅ 9,831,320 MWh generated Jan-Jun 2019 by wind farms

✅ Enough to power 4.47 million homes twice in that period

✅ Advances decarbonization and 2030 renewables, 2050 net-zero goals

Wind turbines in Scotland produced enough electricity in the first half of 2019, reflecting periods when wind led the power mix across the UK, to power every home in the country twice over, according to new data by the analytics group WeatherEnergy. The wind farms generated 9,831,320 megawatt-hours between January and June, as the UK set a wind generation record in comparable periods, equal to the total electricity consumption of 4.47 million homes during that same period.

The electricity generated by wind in early 2019 is enough to power all of Scotland’s homes, as well as a large portion of northern England’s, highlighting how wind and solar exceeded nuclear in the UK in recent milestones as well, and events such as record UK output during Storm Malik underscore this capacity.

“These are amazing figures,” Robin Parker, climate and energy policy manager at WWF, which highlighted the new data, said in a statement. “Scotland’s wind energy revolution is clearly continuing to power ahead, as wind became the UK’s main electricity source in a recent first. Up and down the country, we are all benefitting from cleaner energy and so is the climate.”

Scotland currently has a target of generating half its electricity from renewables by 2030, a goal buoyed by milestones like more UK electricity from wind than coal in 2016, and decarbonizing its energy system almost entirely by 2050. Experts say the latest wind energy data shows the country could reach its goal far sooner than originally anticipated, especially with complementary technologies such as tidal power in Scottish waters gaining traction.

Iran-Iraq Power Grid Deals reinforce electricity and natural gas ties, upgrading transmission in Karbala and Najaf, repairing transformers, easing sanctions bottlenecks, and weighing GCC interconnection to diversify supply and reduce distribution losses across Iraq.

Key Points

Agreements to rehabilitate Iraq's grid, cut losses, and secure power via Iranian gas, electricity, and upgrades.

✅ Reduce distribution losses in Karbala and Najaf

✅ Repair and replace damaged distribution transformers

✅ Coordinate payments to TAVANIR amid US sanctions

Iran and Iraq have finalized two deals to rehabilitate and develop the power grid of Iraq, while Iran is upgrading thermal plants to combined cycle at home to save energy, IRNA cited the Iranian Energy Minister Reza Ardakanian.

Ardakanian met his Iraqi counterpart Majid Mahdi Hantoush in Tehran on Tuesday evening for talks on further energy cooperation on the sidelines of Prime Minister Mustafa al-Kadhimi’s trip to the Islamic Republic on his first foreign visit.

“It was decided that the contracts related to reducing losses on the electricity distribution network in the provinces of Karbala and Najaf, as well as the contract for repairing Iraq’s distribution transformers would be finalized and signed,” the Iranian minister said.

Iraq relies on Iran for natural gas that generates as much as 45 percent of its electricity, with Iran supplying 40% of Iraq’s power according to sector reports. Iran transmits another 1,200 MW directly, and has regional power hub plans as well, making itself an indispensable energy source for its Arab neighbor, but the United States is trying to pry Baghdad away from Tehran’s orbit.

The US has been enlisting its companies and allies such as Saudi Arabia to replace Iran as Iraq’s source of energy.

Iran’s money from exports of gas and electricity has accumulated in bank accounts in Iraq, because US sanctions are preventing Tehran from repatriating it.

In January, an official said the sanctions were giving Iran a run for five billion dollars, “sedimenting” at the Central Bank of Iraq, because Tehran could not access it.

Ardakanian said the issue was brought up in the discussions on Tuesday and it was agreed that “the payment of part of TAVANIR (Iran Power Generation and Transmission Company)’s claims will start from the end of July”.

The US administration is pushing for a deal between Washington, Baghdad and six Persian Gulf states to connect Iraq’s nationwide power grid to that of the Persian Gulf Cooperation Council, while Uzbekistan looks to export power to Afghanistan as regional linkages expand.

The US State Department said in a statement last Thursday that the six countries that make up the (Persian) Gulf Cooperation Council Interconnection Authority (GCCIA) — Saudi Arabia, Kuwait, Bahrain, Qatar, Oman and the UAE — had affirmed their shared support for the project to supply electricity to Iraq.

Iraq needs more than 23,000 MW of electricity to meet its domestic demand, and is exploring nuclear power plans to tackle shortages, but years of war following the 2003 US invasion have left its power infrastructure in tatters and a deficit of some 7,000 MW.

In the past, officials in Baghdad have said there is no easy substitute to imports from Iran because it will take years to adequately build up Iraq’s energy infrastructure, and meeting summer electricity needs remains a persistent challenge.

They have said American demand acknowledges neither Iraq’s energy needs nor the complex relations between Baghdad and Tehran.

In addition to natural gas and electricity, Iraq imports a wide range of goods from Iran including food, agricultural products, home appliances, and air conditioners.

On Tuesday, the Iraqi prime minister said during a joint news conference with Iranian President Hassan Rouhani that the purpose of his trip to Tehran was to strengthen historical ties between the two countries, especially in light of the challenges they faced as a result of the coronavirus outbreak and the fall of oil prices.

“In the face of such challenges, we need coordination between the two countries in a way that serves the interests of Iran and Iraq.”

Both Iran and Iraq, Kadhimi said, suffer from economic problems, adding the two countries need comprehensive and inclusive cooperation to overcome them.

Kadhimi said Iran-Iraq relations are not merely due to the geographical location of the two countries and their 1,450-km border, adding the ties are based on religion and culture and rooted in history.

“I am reiterating to my brothers in the Islamic Republic of Iran that the Iraqi nation is eager to have excellent relations with the Islamic Republic of Iran based on the principle of non-interference in the internal affairs of the two countries.”

Kadhimi said Iran and Iraq fought against terrorism and Takfiri groups together, and the Islamic Republic of Iran was one of the first countries to stand by Iraq.

“We will not forget this. That is why Iraq has stood with Iran to help it overcome economic challenges and turned to a big market for trade with Iran,” he said.

“We seek stability in Iraq and our philosophy and view of Iran is that we consider Iran a stable, strong, prosperous and progressive country, and this fact is in the interest of Iraq and the territorial integrity of the region,” he added.

According to Kadhimi, the two sides discussed implementing agreements between them, including connecting their railway through Khorramshahr in Iran and Basra in Iraq, adding he was very confident the agreements would be implemented soon.

Iraq’s delegation included the ministers of foreign affairs, finance, health, and planning, as well as Kadhimi’s national security adviser, some of whom also met their Iranian counterparts.

Last year, Iran’s exports to Iraq amounted to nearly $9 billion, IRNA reported. It said the two nations will discuss increasing that amount to $20 billion.

“The two governments’ will is to expand bilateral trade to $20 billion,” Rouhani said after an hour-long meeting with the Iraqi prime minister.

Australia's greenhouse gas emissions rose in Q2 as electricity and transport pollution increased, despite renewable energy growth. Net zero targets, carbon dioxide equivalent metrics, and land use changes underscore mixed trends in decarbonisation.

Key Points

About 499-500 Mt CO2-e annually, with a 2% quarterly rise led by electricity and transport.

✅ Q2 emissions rose to 127 Mt from 124.4 Mt seasonally adjusted

✅ Electricity sector up to 41.6 Mt; transport added nearly 1 Mt

✅ Land use remains a net sink; renewables expanded capacity

Australia’s greenhouse gas emissions rose in the June quarter by about 2% as pollution from the electricity sector and transport increased.

Figures released on Tuesday by the Morrison government showed that on a year to year basis, emissions for the 12 months to last June totalled 498.9m tonnes of carbon dioxide equivalent. That tally was down 2.1%, or 10.8m tonnes compared with the same period a year earlier.

However, on a seasonally adjusted quarterly basis, emissions increased to 127m tonnes, or just over 2%, from the 124.4m tonnes reported in the March quarter. For the year to March, emissions totalled 494.2m tonnes, underscoring the pickup in pollution in the more recent quarter even as global coal power declines worldwide.

A stable pollution rate, if not a rising one, is also implied by the government’s release of preliminary figures for the September quarter. They point to 125m tonnes of emissions in trend terms for the July-September months, bringing the year to September total to about 500m tonnes, the latest report said.

The government has made much of Australia “meeting and beating” climate targets. However, the latest statistics show mostly emissions are not in decline despite its pledge ahead of the Glasgow climate summit that the country would hit net zero by 2050, and AEMO says supply can remain uninterrupted as coal phases out over the next three decades.

“Nothing’s happening except for the electricity sector,” said Hugh Saddler, an honorary associate professor at the Australian National University. Once Covid curbs on the economy eased, such as during the current quarter, emission sources such as from transport will show a rise, he predicted.

Falling costs for new wind and solar farms, with the IEA naming solar the cheapest in history worldwide, are pushing coal and gas out of electricity generation, as well as pushing down power prices. In seasonally adjusted terms, though, emissions for that sector rose from 39.7m tonnes the March quarter to 41.6m in the June one.

Most other sectors were steady, with pollution from transport adding almost 1m tonnes in the June quarter.

On an annual basis, a 500m tonnes tally is the lowest since records began in the 1990s, and IEA reported global emissions flatlined in 2019 for context. That lower trajectory, though, is lower due much to the land sector remaining a net sink even as some experts raise questions about the true trends when it comes to land clearing.

According to the government, this sector – known as land use, land-use change and forestry – amounted to a net reduction of emissions of 24.4m tonnes, or almost negative 5% of the national total, in the year to June.

“The magnitude of this net sink has decreased by 0.6% (0.2 Mt CO2-e) on the previous 12 months due to an increase in emissions from agricultural soils, partially offset by a continuing decline in land clearing emissions,” the latest report said.

For its part, the government also touted the increase of renewable energy, as seen in Canada's electricity progress too, as central to driving emissions lower.

“Since 2017, Australia’s consumption of renewable energy has grown at a compound annual rate of 4.6%, with more than $40bn invested in Australia’s renewable energy sector,” Angus Taylor, the federal energy minister said, while UK net zero policy changes show a different approach. “Last year, Australia deployed new solar and wind at eight times the global per capita average.”

ANU’s Saddler said the main driver had been the 2020 Renewable Energy Target that the Coalition government had cut, and had anyway been implemented “a very considerable time ago”.

Tim Baxter, the Climate Council’s senior researcher, said “the time for leaning on the achievements of others is long since past”.

“We need a federal government willing to step up on emissions reductions and take charge with real policy, not wishlists,” he said, referring to the government’s net zero plan to rely on technologies to cut pollution in pursuit of a sustainable electric planet in practice, some of which don’t exist now.

Muskrat Falls rate mitigation offsets Newfoundland Power's rate stabilization decrease as NL Hydro begins cost recovery; Public Utilities Board approval enables collections while Labrador-Island Link nears commissioning, stabilizing electricity rates despite megaproject delays, overruns.

Key Points

Muskrat Falls rate mitigation is NL Hydro's cost recovery via power rates to stabilize bills as commissioning nears.

✅ Offsets 6.4% decrease with a 6.1% rate increase

✅ About 6% now funds NL Hydro's rate mitigation

✅ Collections begin as Labrador-Island Link nears commissioning

With their July electricity bill, Newfoundland Power customers have begun paying for Muskrat Falls, though a lump-sum credit was also announced to offset costs and bills haven't significantly increased — yet.

In a July newsletter, Newfoundland Power said electricity bills were set to decrease by 6.4 per cent as part of the annual rate stabilization adjustment, which reflects the cost of electricity generation.

Instead, that decrease has been offset by a 6.1 increase in electricity rates so Newfoundland and Labrador Hydro can begin recovering the cost of Muskrat Falls, with a $5.2-billion federal package also underpinning the project, the $13-billion hydroelectric megaproject that is billions over budget and years behind schedule.

That means for residential customers, electricity rates will decrease to 12.346 cents per kilowatt, though the basic customer charge will go up slightly from $15.81 to $15.83. According to an N.L. Hydro spokesperson, about six per cent of electricity bills will now go toward what it calls a "rate mitigation fund." 

N.L. Hydro claims victory in Muskrat Falls arbitration dispute with Astaldi
Software troubles blamed for $260M Muskrat Falls cost increase, with N.L. power rates stable for now
The spokesperson said N.L. Hydro is expecting the rate increase to result in $43 million this year, according to a recent financial update from the energy corporation — a tiny fraction of the project's cost. 

N.L. Hydro asked the Public Utilities Board to approve the rate increase, a process similar to Nova Scotia's recent 14% approval by its regulator, in May. In a letter, Energy, Industry and Technology Minister Andrew Parsons supported the increase, though he asked N.L. Hydro to keep electricity rates "as close to current levels as possible. 

Province modifies order in council
Muskrat Falls is not yet fully online — largely due to software problems with the Labrador-Island Link transmission line — and an order in council dictated that ratepayers on the island of Newfoundland would not begin paying for the project until the project was fully commissioned. 

The provincial government modified that order in council so N.L. Hydro can begin collecting costs associated with Muskrat Falls once the project is "nearing" commissioning.

In June, N.L. Hydro said the project was expected to finally be completed by the end of the year.

In an interview with CBC News, Progressive Conservative interim leader David Brazil said the decision to begin recovering the cost of Muskrat Falls from consumers should have been delayed.

"There was an opportunity here for people to get some reprieve when it came to their electricity bills and this administration chose not to do that, not to help the people while they're struggling," he said.

In a statement, Parsons said reducing the rate was not an option, and would have resulted in increased borrowing costs for Muskrat Falls.

"Reducing the rate for one year to have it increase significantly the following year is not consistent with rate mitigation and also places an increased financial burden on taxpayers one year from now," Parsons said.

Decision 'reasonable': Consumer advocate
Brazil said his party didn't know the payments from Muskrat Falls would start in July, and criticized the government for not being more transparent.

Newfoundland and Labrador consumer advocate Dennis Browne said the decision to begin collecting costs from consumers was "reasonable."

"We're into a financial hole due to Muskrat Falls, and what has happened is in order to stabilize rates, we have gone into rate stabilization efforts," he said.

In February, the provincial and federal governments signed a complex agreement to shield ratepayers aimed at softening the worst of the financial impact from Muskrat Falls. Browne noted even with the agreement, the provincial government will have to pay hundreds of millions in order to stabilize electricity rates.

"Muskrat Falls would cost us $0.23 a kilowatt, and that is out of the range of affordability for most people, and that's why we're into rate mitigation," he said. "This was part of a rate mitigation effort, and I accepted it as part of that."

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

Key Points

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

✅ USGS lists magnitude 5.1 at 38 km depth

✅ Near Bushehr nuclear power plant; built for stronger quakes

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

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

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

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

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

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