Projects in developing world worth billions

Site C 500 kV transmission lines strengthen the BC Hydro grid, linking the new substation and Peace Canyon via a 75 kilometre right-of-way to deliver clean energy, with 400 towers built and both circuits energized.

Key Points

High-voltage lines connecting Site C substation to the BC Hydro grid, delivering clean energy via Peace Canyon.

✅ Two 75 km circuits between Site C and Peace Canyon

✅ Connect new 500 kV substation to BC Hydro grid

✅ Over 400 towers built along existing right-of-way

The second and final 500 kilovolt, 75 kilometre transmission line on the Site C project, which has faced stability questions in recent years, has been completed and energized.

With this milestone, the work to connect the new Site C substation to the BC Hydro grid, amid treaty rights litigation that has at times shaped schedules, is complete. Once the Site C project begins generating electricity, much like when the Maritime Link first power flowed between Newfoundland and Nova Scotia, the transmission lines will help deliver clean energy to the rest of the province.

The two 75 kilometre transmission lines run along an existing right-of-way between Site C and the Peace Canyon generating station, a route that has seen community concerns from some northerners. The project’s first 500 kilovolt, 75 kilometre transmission line – along with the Site C substation – were both completed and energized in the fall of 2020.

BC Hydro awarded the Site C transmission line construction contract to Allteck Line Contractors Inc. (now Allteck Limited Partnership) in 2018. Since construction started on this part of the project in summer 2018, crews have built more than 400 towers and strung lines, even as other interties like the Manitoba-Minnesota line have faced scheduling uncertainty, over a total of 150 kilometres.

The two transmission lines are a major component of the Site C project, comparable to initiatives such as the New England Clean Power Link in scale, which also consists of the new 500 kilovolt substation and expanding the existing Peace Canyon 500 kilovolt gas-insulated switchgear to incorporate the two new 500 kilovolt transmission line terminals.

Work to complete three other 500 kilovolt transmission lines that will span one kilometre between the Site C generating station and Site C substation, similar to milestones on the Maritime Link project, is still underway. This work is expected to be complete in 2023.

US SF6 Emissions Decline as NOAA analysis and EPA mitigation show progress, with atmospheric measurements and Greenhouse Gas Reporting verifying reductions from the electric power grid; sulfur hexafluoride's extreme global warming potential underscores inventory improvements.

Key Points

A documented drop in US sulfur hexafluoride emissions, confirmed by NOAA atmospheric data and EPA reporting reforms.

✅ NOAA towers and aircraft show 2007-2018 decline

✅ EPA reporting and utility mitigation narrowed inventory gaps

✅ Winter leaks and servicing signal further reduction options

A new NOAA analysis shows U.S. emissions of the super-potent greenhouse gas sulfur hexafluoride (SF6) have declined between 2007-2018, likely due to successful mitigation efforts by the Environmental Protection Agency (EPA) and the electric power industry, with attention to SF6 in the power industry across global markets. 

At the same time, significant disparities that existed previously between NOAA’s estimates, which are based on atmospheric measurements, and EPA’s estimates, which are based on a combination of reported emissions and industrial activity, have narrowed following the establishment of the EPA's Greenhouse Gas Reporting Program. The findings, published in the journal Atmospheric Chemistry and Physics, also suggest how additional emissions reductions might be achieved. 

SF6 is most commonly used as an electrical insulator in high-voltage equipment that transmits and distributes electricity, and its emissions have been increasing worldwide as electric power systems expand, even as regions hit milestones like California clean energy surpluses in recent years. Smaller amounts of SF6 are used in semiconductor manufacturing and in magnesium production. 

SF6 traps 25,000 times more heat than carbon dioxide over a 100-year time scale for equal amounts of emissions, and while CO2 emissions flatlined in 2019 globally, that comparison underscores the potency of SF6. That means a relatively small amount of the gas can have a significant impact on climate warming. Because of its extremely large global warming potential and long atmospheric lifetime, SF6 emissions will influence Earth’s climate for thousands of years.

In this study, researchers from NOAA’s Global Monitoring Laboratory, as record greenhouse gas concentrations drive demand for better data, working with colleagues at EPA, CIRES, and the University of Maryland, estimated U.S. SF6 emissions for the first time from atmospheric measurements collected at a network of tall towers and aircraft in NOAA’s Global Greenhouse Gas Reference Network. The researchers provided an estimate of SF6 emissions independent from the EPA’s estimate, which is based on reported SF6 emissions for some industrial facilities and on estimated SF6 emissions for others.

“We observed differences between our atmospheric estimates and the EPA’s activity-based estimates,” said study lead author Lei Hu, a Global Monitoring Laboratory researcher who was a CIRES scientist at the time of the study. “But by closely collaborating with the EPA, we were able to identify processes potentially responsible for a significant portion of this difference, highlighting ways to improve emission inventories and suggesting additional emission mitigation opportunities, such as forthcoming EPA carbon capture rules for power plants, in the future.” 

In the 1990s, the EPA launched voluntary partnerships with the electric power, where power-sector carbon emissions are falling as generation shifts, magnesium, and semiconductor industries to reduce SF6 emissions after the United States recognized that its emissions were significant. In 2011, large SF6 -emitting facilities were required to begin tracking and reporting their emissions under the EPA Greenhouse Gas Reporting Program. 

Hu and her colleagues documented a decline of about 60 percent in U.S. SF6 emissions between 2007-2018, amid global declines in coal-fired power in some years—equivalent to a reduction of between 6 and 20 million metric tons of CO2 emissions during that time period—likely due in part to the voluntary emission reduction partnerships and the EPA reporting requirement. A more modest declining trend has also been reported in the EPA’s national inventories submitted annually under the United Nations Framework Convention on Climate Change. 

Examining the differences between the NOAA and EPA independent estimates, the researchers found that the EPA’s past inventory analyses likely underestimated SF6 emissions from electrical power transmission and distribution facilities, and from a single SF6 production plant in Illinois. According to Hu, the research collaboration has likely improved the accuracy of the EPA inventories. The 2023 draft of the EPA’s U.S. Greenhouse Gas Emissions and Sinks: 1990-2021 used the results of this study to support revisions to its estimates of SF6 emissions from electrical transmission and distribution. 

The collaboration may also lead to improvements in the atmosphere-based estimates, helping NOAA identify how to expand or rework its network to better capture emitting industries or areas with significant emissions, according to Steve Montzka, senior scientist at GML and one of the paper’s authors.

Hu and her colleagues also found a seasonal variation in SF6 emissions from the atmosphere-based analysis, with higher emissions in winter than in summer. Industry representatives identified increased servicing of electrical power equipment in the southern states and leakage from aging brittle sealing materials in the equipment in northern states during winter as likely explanations for the enhanced wintertime emissions—findings that suggest opportunities for further emissions reductions.

“This is a great example of the future of greenhouse gas emission tracking, where inventory compilers and atmospheric scientists work together to better understand emissions and shed light on ways to further reduce them,” said Montzka.

Japan Offshore Wind Investment signals Japanese utilities entering UK offshore wind, as J-Power and Kansai Electric buy into Innogy's Triton Knoll, leveraging North Sea expertise, 9.5MW turbines, and 15-year fixed-rate contracts.

Key Points

Japanese utilities buying UK offshore wind stakes to import expertise, as J-Power and Kansai join Innogy's Triton Knoll.

✅ $900M deal: J-Power 25%, Kansai Electric ~16% in Innogy unit

✅ Triton Knoll: 860MW, up to 90 9.5MW turbines, 15-year fixed PPA

✅ Goal: Transfer North Sea expertise to develop Japan offshore wind

Two of Japan's biggest power companies will buy around 40% of a German-owned developer of offshore wind farms in the U.K., seeking to learn from Britain's lead in this sector, as highlighted by a UK offshore wind milestone this week, and bring the know-how back home.

Tokyo-based Electric Power Development, better known as J-Power, will join Osaka regional utility Kansai Electric Power in investing in a unit of Germany's Innogy.

The deal, estimated to be worth around $900 million, will give J-Power a 25% stake and Kansai Electric a roughly 16% share. It will mark the first investment in an offshore wind project by Japanese power companies, as other markets shift strategies, with Poland backing wind over nuclear signaling broader momentum.

Innogy plans to start up the 860-megawatt Triton Knoll offshore wind project -- one of the biggest of its kind in the world -- in the North Sea in 2021. The vast installation will have up to 90 9.5MW turbines and sell its output to local utilities under a 15-year fixed-rate contract.

J-Power, which supplies mainly fossil-fuel-based electricity to Japanese regional utilities, will set up a subsidiary backed by the government-run Development Bank of Japan to participate in the Innogy project. Engineers will study firsthand construction and maintenance methods.

While land-based wind turbines are proliferating worldwide, offshore wind farms have progressed mainly in Europe, though U.S. offshore wind competitiveness is improving in key markets. Installed capacity totaled more than 18,000MW at the end of 2017, which at maximum capacity can produce as much power as 18 nuclear reactors.

Japan has hardly any offshore wind farms in commercial operation, and has little in the way of engineering know-how in this field or infrastructure for linking such installations to the land power grid, with a recent Japan grid blackout analysis underscoring these challenges. But there are plans for a total of 4,000MW of offshore wind power capacity, including projects under feasibility studies.

J-Power set up a renewable energy division in June to look for opportunities to expand into wind and geothermal energy in Japan, and efforts like a Japan hydrogen energy system are emerging to support decarbonization. Kansai Electric also seeks know-how for increasing its reliance on renewable energy, even as it hurries to restart idled nuclear reactors.

They are not the only Japanese investors is in this field. In Asia, trading house Marubeni will invest in a Taiwanese venture with plans for a 600MW offshore wind farm.

NL Hydro electricity credit delivers a one-time on-bill rebate from the rate stabilization fund, linked to oil prices and the Holyrood plant, via the Public Utilities Board, with payment deferrals and interest relief for customers.

Key Points

A one-time on-bill credit from the rate stabilization fund to cut power costs as oil prices remain low.

✅ One-time on-bill credit via the Public Utilities Board

✅ Funded by surplus in the rate stabilization fund

✅ Deferrals and 15 months interest assistance available

Most people who pay electricity bills will get a one-time credit as early as July.

The provincial government on Thursday outlined a new directive to the Public Utilities Board to provide a one-time credit for customers whose electricity rates are affected by the price of oil, part of an effort to shield ratepayers from Muskrat Falls overruns through recent agreements.

Electricity customers who are not a part of the Labrador interconnected system, including those using diesel on the north coast of Labrador, will receive the credit.

The credit, announced at a press conference Thursday morning, will come from the rate stabilization fund and comes as many customers have begun paying for Muskrat Falls on their bills, which has an estimated surplus of about $50 million because low oil prices mean NL Hydro has spent less on fuel for the Holyrood thermal generating station.

Normally a surplus would be paid out over a year, but customers this year will get the credit in a lump sum, as early as July, with the amount varying based on electricity usage.

"Given the difficult times many are finding themselves in, we believe an upfront, one-time on-bill credit would be much more helpful for customers than a small monthly decrease over the next 12 months," said Natural Resources Minister Siobhan Coady at the provincial government's announcement Thursday morning.

Premier Dwight Ball said with many households and businesses experiencing financial hardship, the one-time credit is meant to make life a little easier, noting that Nova Scotia's premier has urged regulators to reject a major hike elsewhere.

"We have requested that the board of commissioners of the Public Utilities Board, even as Nova Scotia's regulator approved a 14% increase recently, adopt a policy so that a credit will be dispersed immediately," Ball said.

"This is to help people when they need it the most.… We're doing what we can to support you."

The provincial government estimates someone whose power costs an average of $200 a month would get a one-time credit of about $130. Details of the plan will be left to the PUB.

Deferred payments allowed
Ball said the credit will make a "significant impact" on customers' July bills.

Both businesses and residential customers will also be able to defer payments, similar to Alberta's deferral program that shifted costs for unpaid bills, with up to $2.5 million in interest being waived on overdue accounts. Customers will be required to make agreed-upon monthly payments to their account, and there will be interest assistance for 15 months, beginning June 1.

Coady said customers can renegotiate their bills and defer payments, with the province picking up the tab for the interest.

"You can speak to a customer service agent and they will make accommodations, but you have to continue to make some version of a monthly payment," Coady

"The interest that may be accrued is going to be paid for by the provincial government, so if you're a business, a person, and you're having difficulty and you can't make what I would say is your normal payment, call your utility, make some arrangements."

Labrador's interconnected grid isn't affected by the price of oil, but those customers can take advantage of the interest relief.

Relief policies already put in place during the pandemic, like not disconnecting customers and providing options for more flexible bill payments, will continue, as utilities such as Hydro One reconnecting customers demonstrate in Ontario.

Credit not enough to support customers: PCs
While Ball said his government is doing what they can to help ratepayers, the opposition doesn't believe the announcement does enough to support those who need it.

Tony Wakeham, the Progressive Conservative MHA for Stephenville-Port au Port, said in a statement Thursday the credit simply gives people's money back to them, after the NL Consumer Advocate called an 18% rate hike unacceptable, and Newfoundland Power stands to benefit. 

"The Liberal government would like ratepayers to believe that they are getting electricity rate relief, but in reality, customers would have been entitled to receive the value of this credit anyway over a 12-month period. Furthermore, in providing a one-time credit, Newfoundland Power will also be able to collect an administrative fee, adding to their revenues," Wakeham said in the statement.

"People and businesses in this province are struggling to pay their utility bills, and the Liberal government should help them by putting extra money into their pockets, not by recycling an already existing program to the benefit of a large corporation."

Wakeham called on government to direct the PUB to lower Newfoundland Power's guaranteed rate of return to give cash refunds to customers, and for Newfoundland Power to waive its fees.

Alberta Electricity Peak Demand surged to 10,638 MW, as AESO reported record summer load from air conditioning, Stampede visitors, and heatwave conditions, with ample generation capacity, stable grid reliability, and conservation urged during 5-7 p.m.

Key Points

It is the record summer power load in Alberta, reaching 10,638 MW, with evening conservation urged by AESO.

✅ Record 10,638 MW at 4 pm; likely to rise this week

✅ Drivers: A/C use, heat, Stampede visitors

✅ AESO reports ample capacity; conserve 5-7 pm

Consumer use hit 10,638 MW, blowing past a previous high of 10,520 MW set on July 9, 2015, said the Alberta Electric System Operator (AESO).

“We hit a new summer peak and it’s likely we’ll hit higher peaks as the week progresses,” said AESO spokeswoman Tara De Weerd.

“We continue to have ample supply, and as Alberta's electricity future trends toward more wind, our generators are very confident there aren’t any issues.”

That new peak was set at 4 p.m. but De Weerd said it was likely to be exceeded later in the day.

Heightened air conditioner use is normally a major driver of such peak electricity consumption, said De Weerd.

She also said Calgary’s big annual bash is also likely playing a role.

“It’s the beginning of Stampede, you have an influx of visitors so you’ll have more people using electricity,” she said.

Alberta’s generation capacity is 16,420 MW, said the AESO, with wind power increasingly outpacing coal in the province today.

There are no plans, she said, for any of the province’s electricity generators to shut down any of their plants for maintenance or other purposes in the near future as demand rises.

The summer peak is considerably smaller than that reached in the depths of Alberta’s winter.

Alberta’s winter peak usage was recorded last year and was 11,458 MW.

Though the province’s capacity isn’t being strained by the summer heat, De Weerd still encouraged consumers to go easy during the peak use time of the day, between 5 and 7 p.m.

“We don’t have to be running all of our appliances at once,” she said.

Alberta exports an insignificant amount of electricity to Montana, B.C. and Saskatchewan, where demand recently set a new record.

The weather forecast calls for temperatures to soar above 30C through the weekend.

In northern Canada, Yukon electricity demand recently hit a record high, underscoring how extreme temperatures can strain systems.

Renewables 2020 Global Status Report highlights renewable energy gaps beyond power, urging decarbonization in heating, cooling, and transport, greener COVID-19 recovery, market reforms, and rapid energy transition to cut CO2 emissions and fossil fuel dependence.

Key Points

REN21's annual report on renewable energy progress and policy gaps across power, heating, cooling, and transport.

✅ Calls for decarbonizing heating, cooling, and transport.

✅ Warns COVID-19 recovery must avoid fossil fuel lock-in.

✅ Urges market reforms to boost energy efficiency and renewables.

Growth in renewable power has been impressive over the past five years, with over 30% of global electricity now coming from renewables worldwide. But too little is happening in heating, cooling and transport. Overall, global hunger for energy keeps increasing and eats up progress, according to REN21's Renewables 2020 Global Status Report (GSR), released today. The journey towards climate disaster continues, unless we make an immediate switch to efficient and renewable energy in all sectors in the wake of the COVID-19 pandemic.

"Year after year, we report success after success in the renewable power sector. Indeed, renewable power has made fantastic progress. It beats all other fuels in growth and competitiveness. Many national and global organisations already cry victory. But our report sends a clear warning: The progress in the power sector is only a small part of the picture. And it is eaten up as the world's energy hunger continues to increase. If we do not change the entire energy system, we are deluding ourselves," says Rana Adib, REN21's Executive Director.

The report shows that in the heating, cooling and transport sectors, the barriers are still nearly the same as 10 years ago. "We must also stop heating our homes and driving our cars with fossil fuels," Adib claims.

There is no real disruption in the COVID-19 pandemic

In the wake of the extraordinary economic decline due to COVID-19, the IEA predicts energy-related CO2 emissions are expected to fall by up to 8% in 2020. But 2019 emissions were the highest ever, and the relief is only temporary. Meeting the Paris targets would require an annual decrease of at least 7.6% to be maintained over the next 10 years, and UN analysis on NDC ambition underscores the need for faster action. Says Adib: "Even if the lock-downs were to continue for a decade, the change would not be sufficient. At the current pace, with the current system and current market rules, it would take the world forever to come anywhere near a no-carbon system."

"Many recovery packages lock us into a dirty fossil fuel economy"

Recovery packages offer a once-in-a-lifetime chance to make the shift to a low-carbon economy, and green energy investments could accelerate COVID-19 recovery. But according to Adib there is a great risk for this enormous chance to be lost. "Many of these packages include ideas that will instead lock us further into a dirty fossil fuel system. Some directly promote natural gas, coal or oil. Others, though claiming a green focus, build the roof and forget the foundation," she says. "Take electric cars and hydrogen, for example. These technologies are only green if powered by renewables."

Choosing an energy system that supports job creation and social justice

The report points out that "green" recovery measures, such as investment in renewables and building efficiency, are more cost-effective than traditional stimulus measures and yield more returns. It also documents that renewables deliver on job creation, energy sovereignty, accelerated energy access in developing countries, and clean, affordable and sustainable electricity for all objectives worldwide, alongside reduced emissions and air pollution.

"Renewables are now more cost-effective than ever, and recent IRENA analysis shows their potential to decarbonise the energy sector, providing an opportunity to prioritize clean economic recovery packages and bring the world closer to meeting the Paris Agreement Goals. Renewables are a key pillar of a healthy, safe and green COVID-19 recovery that leaves no one behind," said Inger Andersen, Executive Director of the UN Environment Programme (UNEP). "By putting energy transition at the core of economic recovery, countries can reap multiple benefits, from improved air quality to employment generation."

This contrasts with the true cost of fossil fuels, estimated to be USD 5.2 trillion if costs of negative impacts such as air pollution, effects of climate change, and traffic congestion are counted.

Renewable energy systems support energy sovereignty and democracy, empowering citizens and communities, instead of big fossil fuel producers and consumers. "When spending stimulus money, we have to decide: Do we want an energy system that serves some or a system that serves many?", says Adib. "But it's not only about money. We must end any kind of support to the fossil economy, particularly when it comes to heating, cooling and transport. Governments need to radically change the market conditions and rules and demonstrate the same leadership as during the COVID-19 pandemic."

The report finds:

Total final energy demand continues to be on the rise (1.4% annually from 2013 to 2018). Despite significant progress in renewable power generation, the share of renewables in total final energy demand barely increased (9.6% in 2013 to 11% in 2018). Compared to the power sector, the heating, cooling and transport sectors lag far behind (renewable energy share in power, 26%, heating and cooling, 10%, transport, 3%).

Today's progress is largely the result of policies and regulations initiated years ago and focus on the power sector. Major barriers seen in heating, cooling and transport are still almost the same a decade on. Policies are needed to create the right market conditions.

The renewable energy sector employed around 11 million people worldwide in 2018

In 2019, the private sector signed power purchase agreements (PPAs) for a record growth of over 43% from 2018 to 2019 in new renewable power capacity.

The global climate strikes have reached unprecedented levels with millions of people across 150 countries. They have pushed governments to step up climate ambitions. As of April 2020, 1490 jurisdictions - spanning 29 countries and covering 822 million citizens - had issued "climate emergency" declarations, many of which include plans and targets for more renewable-based energy systems.

While some countries are phasing out coal, examples such as Europe's green surge show how renewables can soar as emissions fall, yet others continued to invest in new coal-fired power plants. In addition, funding from private banks for fossil fuel projects has increased each year since the signing of the Paris Agreement, totaling USD 2.7 trillion over the last three years.

"It is clear, renewable power has become mainstream and that is great to see. But the progress in this one sector should not lead us to believe that renewables are a guaranteed success. Governments need to take action beyond economic recovery packages. They also need to create the rules and the environment to switch to an efficient and renewables-based energy system, and action toward 100% renewables is urgently needed worldwide. Globally. Now." concludes Arthouros Zervos, President of REN21.
