At 1.2 million volts, a new circuit breaker installed in India is the highest alternating current AC voltage breaker in the world and will support the countryÂ’s ultrahigh voltage grid plans.

ABB has designed, manufactured, installed and commissioned a 1,200-kilovolt kV circuit breaker the highest AC voltage level in the world. Once the 1200 kV ultrahigh-voltage switchgear is fully operational, it will have a switching capacity of 10,400 megawatts - a switch capable of turning ‘ON’ or ‘OFF’ the electricity generated by 10 large power plants or the combined average annual electrical load of Switzerland and Denmark, within milliseconds.

The circuit breaker is deployed at the 1,200 kV national test station constructed by Power Grid Corporation of India Limited PGCIL, IndiaÂ’s central transmission utility, at Bina in the central Indian state of Madhya Pradesh.

Alongside the circuit breaker, the state-of-the-art hybrid switchgear solution comprises a gas-insulated disconnector, current transformers and monitoring and diagnostic equipment. The solution requires only half of the space that would be needed for one with conventional air-insulated designs. The configuration also protects critical components from environmental exposure and makes it more resilient against earthquakes.

India is adding substantial power generation capacity to meet growing demand, which in turn requires an efficient and reliable transmission and distribution infrastructure to deliver the electricity to consumers.

Transmitting power at higher voltages increases the amount of electricity that can be transported along a line with significantly lowers transmission losses, and at the same time saves space and reduces environmental impact. These are some of the considerations which have prompted India to develop a 1,200-kV transmission system.

“ABB has a long track record in India and we are pleased to continue to support the country in the development of an efficient and reliable power grid. Ultra high-voltage technologies are especially suitable for large countries such as India where power often has to be transmitted over large distances from generation to load centers in the most efficient way,” said Bernhard Jucker, head of ABB’s Power Products division.

“PGCIL is fully engaged in developing a robust and integrated national grid along with reliable partners in technology like ABB. This development takes us a step further in the development of our ultra high-voltage transmission network,” said R N Nayak, Chairman and Managing Director of PGCIL.

In a power system, switchgear is used to control, protect and isolate electrical equipment to ensure the reliability of the electricity supply. ABB has over 80 yearsÂ’ experience in switching technology and has pioneered several innovations over the years.

Planning for Toronto?s Growing Electricity Needs

Toronto Grid Upgrade expands electricity capacity and reliability with new substations, upgraded transmission lines, and integrated renewable energy, supporting EV growth, sustainability goals, and resilient power for Toronto's growing residential and commercial sectors.

 

Key Points

A joint plan to boost grid capacity, add renewables, and improve reliability for Toronto's rising power demand.

✅ New substations and upgraded transmission lines increase capacity

✅ Integrates solar, wind, and storage for cleaner, reliable power

✅ Supports EV adoption, reduces outages, and future-proofs the grid

 

As Toronto's population and economy continue to expand, the surge in electricity demand in the city is also increasing rapidly. In response, the Ontario government, in partnership with the City of Toronto and various stakeholders, has launched an initiative to enhance the electricity infrastructure to meet future needs.

The Ontario Ministry of Energy and the City of Toronto are focusing on a multi-faceted approach that includes upgrades to existing power systems and the integration of renewable energy sources, as well as updated IoT cybersecurity standards for sector devices. This initiative is critical as Toronto looks towards a sustainable future, with projections indicating significant growth in both residential and commercial sectors.

Energy Minister Todd Smith highlighted the urgency of this project, stating, “With Toronto's growing population and dynamic economy, the need for reliable electricity cannot be overstated. We are committed to ensuring that our power systems are not only capable of meeting today's demands but are also future-proofed against the needs of tomorrow.”

The plan involves substantial investments in grid infrastructure to increase capacity and improve reliability. This includes the construction of new substations and the enhancement of old ones, along with the upgrading of transmission lines and exploration of macrogrids to strengthen reliability. These improvements are designed to reduce the frequency and severity of power outages while accommodating new developments and technologies such as electric vehicles, which are expected to place additional demands on the system.

Additionally, the Ontario government is exploring the potential for renewable energy sources, such as rooftop solar grids and wind, to be integrated into the city’s power grid. This shift towards green energy is part of a broader effort to reduce carbon emissions and promote environmental sustainability.

Toronto Mayor John Tory emphasized the collaborative nature of this initiative, stating, “This is a prime example of how collaboration between different levels of government and the private sector can lead to innovative solutions that benefit everyone. By enhancing our electricity infrastructure, we are not only improving the quality of life for our residents but also supporting Toronto's competitive edge as a global city.”

The project also includes a public engagement component, where citizens are encouraged to provide input on the planning and implementation phases. This participatory approach ensures that the solutions developed are in alignment with the needs and expectations of Toronto's diverse communities.

Experts agree that the timing of these upgrades is critical. As urban populations grow, the strain on infrastructure, especially in a powerhouse like Toronto, can lead to significant challenges. Proactive measures, such as those being implemented by Ontario and Toronto, and mirrored by British Columbia's clean energy shift underway on the west coast, are essential in avoiding potential crises and ensuring economic stability.

The success of this initiative could serve as a model for other cities facing similar challenges, highlighting the importance of forward-thinking and cooperation in urban planning and energy management. As Toronto moves forward with these ambitious plans, the eyes of the world, particularly other urban centers, will be watching and learning how to similarly tackle the dual challenges of growth and sustainability, with recent examples like London's newest electricity tunnel demonstrating large-scale grid upgrades.

This strategic approach to managing Toronto's electricity needs reflects a comprehensive understanding of the complexities involved in urban energy systems and a commitment to ensuring a resilient and sustainable future that aligns with Canada's net-zero grid by 2050 goals at the national level for all residents.

Energy-hungry Europe to brighten profit at US solar equipment makers

European Solar Inverter Demand surges as photovoltaics and residential solar expand during the clean energy transition, driven by high natural gas prices; Germany leads, boosting Enphase and SolarEdge sales for rooftop systems and grid-tied installations.

 

Key Points

Rising European need for solar inverters, fueled by residential PV growth, high energy costs, and clean energy policies.

✅ Germany leads EU rooftop PV installations

✅ Enphase and SolarEdge see revenue growth

✅ High gas prices and policies spur adoption

 

Solar equipment makers are expected to post higher quarterly profit, benefiting from strong demand in Europe for critical components that convert energy from the sun into electricity, amid record renewable momentum worldwide.

The continent is emerging as a major market for solar firms as it looks to reduce its dependence on the Russian energy supply and accelerate its clean energy transition, with solar already reshaping power prices in Northern Europe across the region, brightening up businesses of companies such as Enphase Energy (ENPH.O) and SolarEdge Technologies (SEDG.O), which make solar inverters.

Wall Street expects Enphase and SolarEdge to post a combined adjusted net income of $323.8 million for the April-June quarter, a 56.7% jump from a year earlier, even as demand growth slows in the United States.

The energy crisis in Europe is not as acute as last year when Western sanctions on Russia severely crimped supplies, but prices of natural gas and electricity continue to be much higher than in the United States, Raymond James analyst Pavel Molchanov said.

As a result, demand for residential solar keeps growing at a strong pace in the region, with Germany being one of the top markets and solar adoption in Poland also accelerating in recent years across the region.

About 159,000 residential solar systems became operational in the first quarter in Germany amid a solar power boost that reflects policy and demand, a 146% rise from a year earlier, according to BSW solar power association.

Adoption of solar is also helping European homeowners have greater control over their energy costs as fossil fuel prices tend to be more volatile, Morningstar analyst Brett Castelli said.

SolarEdge, which has a bigger exposure to Europe than Enphase, said its first-quarter revenue from the continent more than doubled compared with last year.

In comparison, growth in the United States has been tepid due to lukewarm demand in states like Texas and Arizona where cheaper electricity prices make the economics of residential solar less attractive, even though solar is now cheaper than gas in parts of the U.S. market.

Higher interest rates following the U.S. Federal Reserve's recent actions to tame inflation are also weighing on demand, even as power outage risks rise across the United States.

Analysts also expect weakness in California where a new metering reform reduces the money credited to rooftop solar owners for sending excess power into the grid, underscoring how policy shifts can reshape the sector. The sunshine state accounts for nearly a third of the U.S. residential solar market.

Enphase will report its results on Thursday after the bell, while SolarEdge will release its second-quarter numbers on Aug. 1.

Macron: France, Germany to provide each other with gas, electricity, to weather crisis

France-Germany Energy Solidarity underscores EU energy crisis cooperation: gas supply swaps, electricity imports, price cap talks, and curbs on speculation as Russian pipeline flows halt and winter demand rises across the bloc.

 

Key Points

A pact where France sends gas to Germany as Germany supplies power, bolstering EU cooperation and winter security.

✅ Gas to Germany; power to France amid nuclear outages.

✅ EU price cap, anti-speculation, joint gas purchasing.

✅ No new Spain-France pipeline unless case improves.

 

France will send gas to Germany if needed while Germany stands ready to provide it with electricity, President Emmanuel Macron said on Monday, saying this showcased European solidarity in the face of the energy crisis stemming from the war in Ukraine, which many view as a wake-up call to ditch fossil fuels across the bloc.

European gas prices surged, share prices slid and the euro sank on Monday after Russia stopped pumping gas via a major supply route, and Germany's 200 billion euro package sought to cushion the blow, in another warning to the 27-nation EU as it scrambled to respond to the crisis ahead of winter. read more

"Germany needs our gas and we need power from the rest of Europe, notably Germany," France's president told a news conference as EU electricity reform remains under debate following a phone call with German Chancellor Olaf Scholz.

The necessary connections for France to deliver gas to Germany when needed would be finalised in the coming weeks, he said, adding that France, which had long been a net exporter of electricity, will need help from its neighbours because of technical problems its nuclear plants face. read more

Macron, however, said that he did not understand demand for a third gas link between France and Spain, rejecting calls to increase capacity with a new pipeline.

He added he was open to changing his mind on that point, especially as Germany's utility troubles deepen, should Scholz or Prime Minister Pedro Sanchez argue convincingly for it.

Ahead of a meeting on Friday of EU energy ministers, Macron said France was in favour of buying gas at a European rather than a national level, as emergency electricity measures are weighed, and called for European Union measures to control energy prices.

He said it was necessary to act against speculation on energy prices at EU level, as the EU outlines possible gas price cap strategies for discussion, and also said France was in favour of putting a cap on the price of pipeline Russian gas.

Macron also repeated calls for all to turn down air conditioners when it's hot and to limit heating to 19 degrees Celsius this winter, noting that rolling back electricity prices is tougher than it appears this year.

"Everyone has to do their bit," he said.

Energy Security Support to Ukraine

U.S. Energy Aid to Ukraine delivers emergency electricity grid equipment, generators, transformers, and circuit breakers, supports ENTSO-E integration, strengthens energy security, and advances decarbonization to restore power and heat amid Russian attacks.

 

Key Points

U.S. funding and equipment stabilize Ukraine's power grid, strengthen energy security, and advance ENTSO-E integration.

✅ $53M for transformers, breakers, surge arresters, disconnectors

✅ $55M for generators and emergency heat to municipalities

✅ ENTSO-E integration, cybersecurity, nuclear safety support

 

In the midst of Russia’s continued brutal attacks against Ukraine’s energy infrastructure, Secretary of State Blinken announced today during a meeting of the G7+ on the margins of the NATO Ministerial in Bucharest that the United States government is providing over $53 million to support acquisition of critical electricity grid equipment. This equipment will be rapidly delivered to Ukraine on an emergency basis to help Ukrainians persevere through the winter, as the country prepares for winter amid energy challenges. This supply package will include distribution transformers, circuit breakers, surge arresters, disconnectors, vehicles and other key equipment.

This new assistance is in addition to $55 million in emergency energy sector support for generators and other equipment to help restore emergency power and heat to local municipalities impacted by Russia’s attacks on Ukraine’s power system, while both sides accuse each other of energy ceasefire violations that complicate repairs. We will continue to identify additional support with allies and partners, and we are also helping to devise long-term solutions for grid restoration and repair, along with our assistance for Ukraine’s effort to advance the energy transition and build an energy system decoupled from Russian energy.

Since Russia’s further invasion on February 24, working together with Congress, the Administration has provided nearly $32 billion in assistance to Ukraine, including $145 million to help repair, maintain, and strengthen Ukraine’s power sector in the face of continued attacks. We also have provided assistance in areas such as EU integration and regional electricity trade, including electricity imports to stabilize supply, natural gas sector support to maximize resource development, support for nuclear safety and security, and humanitarian relief efforts to help Ukrainians to overcome the impacts of energy shortages.

Since 2014, the United States has provided over $160 million in technical support to strengthen Ukraine’s energy security, including to strengthen EU interconnectivity, increase energy supply diversification, and promote investments in energy efficiency, renewable energy, and clean energy technologies and innovation.  Much of this support has helped prepare Ukraine for its eventual interconnection with Europe’s ENTSO-E electricity grid, aligning with plans to synchronize with ENTSO-E across the integrated power system, including the island mode test in February 2022 that not only demonstrated Ukraine’s progress in meeting the EU’s technical requirements, but also proved to be critical considering Russia’s subsequent military activity aimed at disrupting power supplies and distribution in Ukraine.

 

Department of Energy (DOE)

  • With the increased attacks on Ukraine’s electricity grid and energy infrastructure in October, DOE worked with the Ukrainian Ministry of Energy and DOE national laboratories to collate, vet, and help prioritize lists of emergency electricity equipment for grid repair and stabilization amid wider global energy instability affecting supply chains.
  • Engaged at the CEO level U.S. private sector and public utilities and equipment manufacturers to identify $35 million of available electricity grid equipment in the United States compatible with the Ukrainian system for emergency delivery. Identified $17.5 million to support purchase and transportation of this equipment.
  • With support from Congress, initiated work on full integration of Ukraine with ENTSO-E to support resumption of Ukrainian energy exports to other European countries in the region, including funding for energy infrastructure analysis, collection of satellite data and analysis for system mapping, and work on cyber security, drawing on the U.S. rural energy security program to inform best practices.
  • Initiated work on a new dynamic model of interdependent gas and power systems of Europe and Ukraine to advance identification and mitigation of critical vulnerabilities.
  • Delivered emergency diesel fuel and other critical materials needed for safe operation of Ukrainian nuclear power plants, as well as initiated the purchase of three truck-mounted emergency diesel backup generators to be delivered to improve plant safety in the event of the loss of offsite power.

U.S. Department of State

  • Building on eight years of technical engagement, the State Department continued to provide technical support to Naftogaz and UkrGasVydobuvannya to advance corporate governance reform, increase domestic gas production, provide strategic planning, and assess critical sub-surface and above-ground technical issues that impact the company’s core business functions.
  • The State Department is developing new programs focused on emissions abatement, decarbonization, and diversification, acknowledging the national security benefits of reducing reliance on fossil fuels to support Ukraine’s ambitious clean energy and climate goals and address the impacts of reduced supplies of natural gas from Russia.
  • The State Department led a decades-long U.S. government engagement to develop and expand natural gas reverse flow (west-to-east) routes to enhance European and Ukrainian energy security. Ukraine is now able to import natural gas from Europe, eliminating the need for Ukraine to purchase natural gas from Gazprom.

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.

B.C. ordered to pay $10M for denying Squamish power project

Greengen Misfeasance Ruling details a B.C. Supreme Court decision awarding $10.125 million over wrongfully denied Crown land and water licence permits for a Fries Creek run-of-river hydro project under a BC Hydro contract.

 

Key Points

A B.C. Supreme Court ruling awarding $10.125M for wrongful denial of Crown land and water licences on Greengen's project.

✅ $10.125M damages for misfeasance in public office

✅ Denial of Crown land tenure and water licence permits

✅ Tied to Fries Creek run-of-river and BC Hydro EPA

 

A B.C. Supreme Court judge has ordered the provincial government to pay $10.125 million after it denied permits to a company that wanted to build a run-of-the river independent power project near Squamish.

In his Oct. 10 decision, Justice Kevin Loo said the plaintiff, Greengen Holdings Ltd., “lost an opportunity to achieve a completed and profitable hydro-electric project” after government representatives wrongfully exercised their legal authority, a transgression described in the ruling as “misfeasance,” with separate concerns reflected in an Ontario market gaming investigation reported elsewhere.

Between 2003 and 2009, the company sought to develop a hydro-electric project on and around Fries Creek, which sits opposite the Brackendale neighbourhood on the other side of the Squamish River. To do so, Greengen Holdings Ltd. required a water licence from the Minister of the Environment and tenure over Crown land from the Minister of Agriculture.

After a lengthy process involving extensive communications between Greengen and various provincial and other ministries and regulatory agencies, the permits were denied, according to Loo. Both decisions cited impacts on Squamish Nation cultural sites that could not be mitigated.

Elsewhere, an Indigenous-owned project in James Bay proceeded despite repeated denials, underscoring varied approaches to community participation.

40-year electricity plan relied on Crown land
The case dates back to December 2005, when BC Hydro issued an open call for power with Greengen. The company submitted a tender several months later.

On July 26, 2006, BC Hydro awarded Greengen an energy purchase agreement, amid evolving LNG electricity demand across the province, under which Greengen would be entitled to supply electricity at a fixed price for 40 years.

Unlike conventional hydroelectric projects, such as new BC generating stations recently commissioned, which store large volumes of water in reservoirs, and in so doing flood large tracts of land, a run of the river project often requires little or no water storage. Instead, from a high elevation, they divert water from a stream or river channel.

Water is then sent into a pressured pipeline known as a penstock, and later passed through turbines to generate electricity, Loo explained, as utilities pursue long-term plans like the Hydro-Québec strategy to reduce fossil fuel reliance. The system returns water to the original stream or river, or into another body of water. 

The project called for most of that infrastructure to be built on Crown land, according to the ruling.

All sides seemed to support the project
In early 2005, company principle Terry Sonderhoff discussed the Fries Creek project in a preliminary meeting with Squamish Nation Chief Ian Campbell.

“Mr. Sonderhoff testified that Chief Campbell seemed supportive of the project at the time,” Loo said.
