State sets lofty goal for wind energy

Ontario Global Adjustment Deferral provides COVID-19 relief to industrial and commercial electricity consumers, holding GA charges at pre-COVID levels, aligning Class A and Class B rates, and deferring non-RPP costs from April to June 2020.

Key Points

An emergency measure that defers a portion of GA charges to stabilize electricity bills for non-RPP Class A/B consumers.

✅ Holds GA near pre-COVID levels at $115/MWh for Class B.

✅ Applies equal percentage relief to Class A customers.

✅ Deferred costs recovered over 12 months from Jan 2021.

Through an emergency order passed today, the Ontario government is taking steps to defer a portion of Global Adjustment (GA) charges for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan for the period starting from April 2020, at a time when Toronto's growing electricity needs require careful planning. This initiative is intended to provide companies with temporary immediate relief on their monthly electricity bills, as utilities use AI to adapt to shifting electricity demands in April, May and June 2020. The government intends to keep this emergency order in place until May 31, 2020, and subsequent regulatory amendments would, if approved, provide for the deferral of these charges for June 2020 as well.

This relief will prevent a marked increase in Global Adjustment charges due to the low electricity demand caused by the COVID-19 outbreak. Without this emergency order, a small industrial or commercial consumer (i.e., Class B) could have seen bills increase by 15 per cent or more. This emergency order will hold GA rates in line with pre-COVID-19 levels, even as clean energy initiatives in British Columbia accelerate across the sector.

"Ontario's industrial and commercial electricity consumers are being impacted by COVID-19. They employ thousands of hardworking Ontarians, and we know this is a challenging time for them," said Greg Rickford, Minister of Energy, Northern Development and Mines. "This would provide immediate financial support for more than 50,000 companies when they need it most: as they do their part to stop the spread of COVID-19 and as they prepare to help get our economy moving again with Toronto preparing for a surge in electricity demand in the years ahead."

Quick Facts

• The GA rate for smaller industrial and commercial consumers (i.e., Class B) has been set at $115 per megawatt-hour, which is roughly in line with the March 2020 value, alongside efforts to develop IoT security standards for electricity sector devices today. Large industrial and commercial consumers (i.e., Class A) will receive the same percentage reduction in GA charges as Class B consumers.
• Subject to the approval of subsequent amendments, deferred costs would be recovered over a 12-month period beginning in January 2021, amid increasing exposure to harsh weather across Canadian grids.

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.

Wildfire Resilient Power Grid Act proposes DOE grants for utility companies to fund wildfire mitigation, grid resilience upgrades, undergrounding power lines, fast-tripping protection, weather monitoring, and vegetation management, prioritizing rural electric cooperatives.

Key Points

A federal bill funding utility wildfire mitigation and grid hardening via DOE grants, prioritizing rural utilities.

✅ $1B DOE matching grants for grid upgrades and wildfire mitigation.

✅ Prioritizes rural utilities; supports undergrounding and hardening.

✅ Funds fast-tripping protection, weather stations, vegetation management.

U.S. Sens. Ron Wyden and Jeff Merkley today introduced new legislation, amid transmission barriers that persist, to incentivize utility companies to do more to reduce wildfire risks as aging power infrastructure ignite wildfires in Oregon and across the West.

Wyden and Merkley's Wildfire Resilient Power Grid Act of 2020 would ensure power companies do their part to reduce the risk of wildfires through power system upgrades, even as California utility spending crackdown seeks accountability, such as the undergrounding of power lines, fire safety equipment installation and proper vegetation management.

"First and foremost, this is a public safety issue. Fire after fire ignited this summer because the aging power grid could not withstand a major windstorm during the season's hottest and driest days," Wyden said. "Many utility companies are already working to improve the resiliency of their power grid, but the sheer costs of these investments must not come at the expense of equitable regulation for rural utility customers. Congress must do all that it can to stop the catastrophic wildfires decimating the West, and that means improving rural infrastructure. By partnering with utilities around the country, we can increase wildfire mitigation efforts at a modest cost -- a fire prevention investment that will pay dividends by saving lives, homes and businesses."

"When this year's unprecedented wildfire event hit, I drove hundreds of miles across our state to see the damage firsthand and to hear directly from impacted communities, so that I could go back to D.C. and work for the solutions they need," said Merkley. "What I saw was apocalyptic--and we have to do everything we can to reduce the risk of this happening again. That means we have to work with our power companies to get critical upgrades and safety investments into place as quickly as possible."

The Wildfire Resilient Power Grid Act of 2020:

* Establishes a $1 billion-per-year matching grant program for power companies through the Department of Energy, even as ACORE opposed DOE subsidy proposals, to reduce the risk of power lines and grid infrastructure causing wildfires.

* Gives special priority to smaller, rural electric companies to ensure mitigation efforts are targeted to forested rural areas.

* Promotes proven methods for reducing wildfire risks, including undergrounding of lines, installing fast-tripping protection systems, and constructing weather monitoring stations to respond to electrical system fire risks.

* Provides for hardening of overhead power lines and installation of fault location equipment where undergrounding of power lines is not a favorable option.

* Ensures fuels management activities of power companies are carried out in accordance with Federal, State, and local laws and regulations.

* Requires power companies to have "skin in the game" by making the program a 1-to-1 matching grant, with an exception for smaller utilities where the matching requirement is one third of the grant.

* Delivers accountability on the part of utilities and the Department of Energy by generating a report every two years on efforts conducted under the grant program.

Portland General Electric President and CEO Maria Pope: "We appreciate Senator Wyden's and Senator Merkley's leadership in proposing legislation to provide federal funding that will help protect Oregon from devastating wildfires. When passed, this will help make Oregon's electric system safer, faster, without increasing customer prices. That is especially important given the economy and hotter, drier summers and longer wildfire seasons that Oregon will continue to face."

Lane County Commission Chair Heather Butch: " In a matter of hours, the entire Lane County community of Blue River was reduced to ashes by the Holiday Farm Fire. Since the moment I first toured that devastation I've been committed to building it back better. I applaud Senators Wyden and Merkley for drafting the Wildfire Resilient Power Grid Act, as it could well provide the path towards meeting this important goal. Moreover, the resultant programs will better protect rural communities from the increasing dangers of wildfires through a number of preventative measures that would otherwise be difficult to implement."

Linn County Commissioner Roger Nyquist: "This legislation is a smart strategic investment for the future safety of our residents as well as the economic vitality of our community."

Marion County Commissioner Kevin Cameron: "After experiencing a traumatic evacuation during the Beachie Creek and Lion's Head wild fires, I understand the need to strengthen the utility Infrastructure. The improvements resulting from Senator Wyden and Merkley's bill will reduce disasters in the future, but improve everyday reliability for our citizens who live, work and protect the environment in potential wildfire areas."

Edison Electric Institute President Tom Kuhn: "EEI thanks Senator Wyden and Senator Merkley for their leadership in introducing the Wildfire Resilient Power Grid Act. This bill will help support and accelerate projects already planned and underway to enhance energy grid resiliency and mitigate the risk of wildfire damage to power lines. Electric companies across the country are committed to working with our government partners and other stakeholders on preparation and mitigation efforts that combat the wildfire threat and on the rapid deployment of technology solutions, including aggregated DERs at FERC, that address wildfire risks, while still maintaining the safe, reliable, and affordable energy we all need."

Oregon Rural Electric Cooperative Association Executive Director Ted Case: "Oregon's electric cooperatives support the Wildfire Resilient Power Grid Act and appreciate Senator Wyden's and Senator Merkley's leadership and innovative approach to wildfire mitigation, particularly for small, rural utilities. This legislation includes targeted assistance that will help us to continue to provide affordable, reliable and safe electricity to over 500,000 Oregonians."

Sustainable Northwest Director of Government Affairs & Program Strategy Dylan Kruse: "In recent years, the West has seen too many wildfires originate due to poorly maintained or damaged electric utility transmission and distribution infrastructure. This legislation plays an important role to ensure that power lines do not contribute to wildfire starts, while providing safe and reliable power to communities during wildfire events. Utilities must, even as Wyoming clean energy bill proposals emerge, live up to their legal requirements to maintain their infrastructure, but this bill provides welcome resources to expedite and prioritize risk reduction, while preventing cost increases for ratepayers."

Oregon Wild Wilderness Program Manager Erik Fernandez: "2020 taught Oregon the lesson that California learned in the Paradise Fire, and SCE wildfire lawsuits that followed underscore the stakes. Addressing the risk of unnaturally caused powerline fires is an increasingly important critical task. I appreciate Senator Ron Wyden's efforts to protect our homes and communities from powerline fires."

Attosecond Electron Transport uses ultrafast lasers and single-cycle light pulses to drive tunneling in bowtie gold nanoantennas, enabling sub-femtosecond switching in optoelectronic nanostructures and surpassing picosecond silicon limits for next-gen computing.

Key Points

A light-driven method that manipulates electrons with ultrafast pulses to switch currents within attoseconds.

✅ Uses single-cycle light pulses to drive electron tunneling

✅ Achieves 600 attosecond current switching in nano-gaps

✅ Enables optoelectronic, plasmonic devices beyond silicon

When it comes to data transfer and computing, the faster we can shift electrons and conduct electricity the better – and scientists have just been able to transport electrons at sub-femtosecond speeds (less than one quadrillionth of a second) in an experimental setup.

The trick is manipulating the electrons with light waves that are specially crafted and produced by an ultrafast laser. It might be a long while before this sort of setup makes it into your laptop, but similar precision is seen in noninvasive interventions where targeted electrical stimulation can boost short-term memory for limited periods, and the fact they pulled it off promises a significant step forward in terms of what we can expect from our devices.

Right now, the fastest electronic components can be switched on or off in picoseconds (trillionths of a second), a pace that intersects with debates over 5G electricity use as systems scale, around 1,000 times slower than a femtosecond.

With their new method, the physicists were able to switch electric currents at around 600 attoseconds (one femtosecond is 1,000 attoseconds).

"This may well be the distant future of electronics," says physicist Alfred Leitenstorfer from the University of Konstanz in Germany. "Our experiments with single-cycle light pulses have taken us well into the attosecond range of electron transport."

Leitenstorfer and his colleagues were able to build a precise setup at the Centre for Applied Photonics in Konstanz. Their machinery included both the ability to carefully manipulate ultrashort light pulses, and to construct the necessary nanostructures, including graphene architectures, where appropriate.

The laser used by the team was able to push out one hundred million single-cycle light pulses every single second in order to generate a measurable current. Using nanoscale gold antennae in a bowtie shape (see the image above), the electric field of the pulse was concentrated down into a gap measuring just six nanometres wide (six thousand-millionths of a metre).

As a result of their specialist setup and the electron tunnelling and accelerating it produced, the researchers could switch electric currents at well under a femtosecond – less than half an oscillation period of the electric field of the light pulses.

Getting beyond the restrictions of conventional silicon semiconductor technology has proved a challenge for scientists, but using the insanely fast oscillations of light to help electrons pick up speed could provide new avenues for pushing the limits on electronics, as our power infrastructure is increasingly digitized and integrated with photonics.

And that's something that could be very advantageous in the next generation of computers: scientists are currently experimenting with the way that light and electronics could work together in all sorts of different ways, from noninvasive brain stimulation to novel sensors.

Eventually, Leitenstorfer and his team think that the limitations of today's computing systems could be overcome using plasmonic nanoparticles and optoelectronic devices, using the characteristics of light pulses to manipulate electrons at super-small scales, with related work even exploring electricity from snowfall under specific conditions.

"This is very basic research we are talking about here and may take decades to implement," says Leitenstorfer.

The next step is to experiment with a variety of different setups using the same principle. This approach might even offer insights into quantum computing, the researchers say, although there's a lot more work to get through yet - we can't wait to see what they'll achieve next.

Northern Pass Hydropower Project Rehearing faces review by New Hampshire's Site Evaluation Committee as Eversource seeks approval for a 192-mile transmission line, citing energy cost relief, while Massachusetts eyes Central Maine Power as an alternative.

Key Points

A review of Eversource's halted NH transmission plan, weighing impacts, costs, and alternatives.

✅ SEC denied project, Eversource seeks rehearing

✅ 192-mile line to bring Canadian hydropower to NE

✅ Alternative bids include Central Maine Power corridor

Groups supporting and opposing the Northern Pass hydropower project in New Hampshire filed statements Friday in advance of a state committee’s meeting next week on whether it should rehear the project.

The Site Evaluation Committee rejected the transmission proposal last month over concerns about potential negative impacts. It is scheduled to deliberate Monday on Eversource’s request for a rehearing.

The $1.6 billion project would deliver hydropower from Canada, including Hydro-Quebec exports, to customers in southern New England through a 192-mile transmission line in New Hampshire.

If the Northern Pass project fails to ultimately win New Hampshire approval, the Massachusetts Department of Energy Resources has announced it will begin negotiating with a team led by Central Maine Power Co. for a $950 million project through a 145-mile Maine transmission line as an alternative.

Separately, construction later began on the disputed $1 billion electricity corridor despite ongoing legal and political challenges.

The Business and Industry Association voted last month to endorse the project after remaining neutral on it since it was first proposed in 2010. A letter sent to the committee Friday urges it to resume deliberations. The association said it is concerned about the severe impact the committee’s decision could have on New Hampshire’s economic future, even as Connecticut overhauls electricity market structure across New England.

“The BIA believes this decision was premature and puts New Hampshire’s economy at risk,” organization President Jim Roche wrote. “New Hampshire’s electrical energy prices are consistently 50-60 percent higher than the national average. This has forced employers to explore options outside New Hampshire and new England to obtain lower electricity prices. Businesses from outside New Hampshire and others now here are reversing plans to grow in New Hampshire due to the Site Evaluation Committee’s decision.”

The International Brotherhood of Electrical Workers and the Coos County Business and Employers Group also filed a statement in support of rehearing the project.

The Society to Protect New Hampshire Forests, which is opposed to the project, said Eversource’s request is premature because the committee hasn’t issued a final written decision yet. It also said Eversource hasn’t proven committee members “made an unlawful or unreasonable decision or mistakenly overlooked matters it should have considered.”

As part of its request for reconsideration, Eversource said it is offering up to $300 million in reductions to low-income and business customers in the state.

It also is offering to allocate $95 million from a previously announced $200 million community fund — $25 million to compensate for declining property values, $25 million for economic development and $25 million to promote tourism in affected areas. Another $20 million would fund energy efficiency programs.

COVID-19 Impact on Electricity Demand, per IEA data, shows 15% global load drop from lockdowns, with residential use up, industrial and service sectors down; fossil fuel generation fell as renewables and photovoltaics gained share.

Key Points

An overview of how lockdowns cut global power demand, boosted residential use, and increased the renewable share.

✅ IEA review shows at least 15% dip in daily global electricity load

✅ Lockdowns cut commercial and industrial demand; homes used more

✅ Fossil fuels fell as renewables and PV generation gained share

The daily demand for electricity dipped at least 15 per cent across the globe, according to Global Energy Review 2020: The impacts of the COVID-19 crisis on global energy demand and CO2 emissions, a report published by the International Energy Agency (IEA) in April 2020, even as global power demand surged above pre-pandemic levels.

The report collated data from 30 countries, including India and China, that showed partial and full lockdown measures adopted by them were responsible for this decrease.

Full lockdowns in countries — including France, Italy, India, Spain, the United Kingdom where daily demand fell about 10% and the midwest region of the United States (US) — reduced this demand for electricity.

Drivers of the fall

There was, however, a spike in residential demand for electricity as a result of people staying and working from home. This increase in residential demand, though, was not enough to compensate for reduced demand from industrial and commercial operations.

The extent of reduction depended not only on the duration and stringency of the lockdown, but also on the nature of the economy of the countries — predominantly service- or industry-based — the IEA report said.

A higher decline in electricity demand was noted in countries where the service sector — including retail, hospitality, education, tourism — was dominant, compared to countries that had industrial economies.

The US, for example — where industry forms only 20 per cent of the economy — saw larger reductions in electricity demand, compared to China, where power demand dropped as the industry accounts for more than 60 per cent of the economy.

Italy — the worst-affected country from COVID-19 — saw a decline greater than 25 per cent when compared to figures from last year, even as power demand held firm in parts of Europe during later lockdowns.

The report said the shutting down of the hospitality and tourism sectors in the country — major components of the Italian economy — were said to have had a higher impact, than any other factor, for this fall.

Reduced fossil fuel dependency

Almost all of the reduction in demand was reportedly because of the shutting down of fossil fuel-based power generation, according to the report. Instead, the share of electricity supply from renewables in the entire portfolio of energy sources, increased during the pandemic, reflecting low-carbon electricity lessons observed during COVID-19.

This was due to a natural increase in wind and photovoltaic power generation compared to 2019 along with a drop in overall electricity demand that forced electricity producers from non-renewable sources to decrease their supplies, before surging electricity demand began to strain power systems worldwide.

The Power System Operation Corporation of India also reported that electricity production from coal — India’s primary source of electricity — fell by 32.2 per cent to 1.91 billion units (kilowatt-hours) per day, in line with India's electricity demand decline reported during the pandemic, compared to the 2019 levels.
