Power surge blows meters off homes

Autonomous Energy Kites harness offshore wind on floating platforms, using carbon fiber wings, tethers, and rotors to generate grid electricity; an airborne wind energy solution backed by Alphabet's Makani to cut turbine costs.

Key Points

Autonomous Energy Kites are tethered craft that capture winds with rotors, generating grid power from floating platforms.

✅ Flies circles on tethers; rotors drive generators to feed the grid.

✅ Operates over deep-sea winds where fixed turbines are impractical.

✅ Lighter, less visual impact, and lower installation costs offshore.

One company's self-flying energy kite may be the answer to increasing wind power around the world, alongside emerging wave power solutions as well.

California-based Makani -- which is owned by Google's parent company, Alphabet -- is using power from the strongest winds found out in the middle of the ocean, where the offshore wind sector has huge potential, typically in spots where it's a challenge to install traditional wind turbines. Makani hopes to create electricity to power communities across the world.

Despite a growing number of wind farms in the United States and the potential of this energy source, lessons from the U.K. underscore how to scale, yet only 6% of the world's electricity comes from wind due to the the difficulty of setting up and maintaining turbines, according to the World Wind Energy Association.

When the company's co-founders, who were fond of kiteboarding, realized deep-sea winds were largely untapped, they sought to make that energy more accessible. So they built an autonomous kite, which looks like an airplane tethered to a base, to install on a floating platform in water, as part of broader efforts to harness oceans and rivers for power across regions. Tests are currently underway off the coast of Norway.

"There are many areas around the world that really don't have a good resource for renewable power but do have offshore wind resources," Makani CEO Fort Felker told Rachel Crane, CNN's innovation correspondent. "Our lightweight kites create the possibility that we could tap that resource very economically and bring renewable power to hundreds of millions of people."

This technology is more cost-efficient than a traditional wind turbine, which is a lot more labor intensive and would require lots of machinery and installation.

The lightweight kite, which is made of carbon fiber, has an 85-foot wingspan. The kite launches from a base station and is constrained by a 1,400-foot tether as it flies autonomously in circles with guidance from computers. Crosswinds spin the kite's eight rotors to move a generator that produces electricity that's sent back to the grid through the tether.

The kites are still in the prototype phase and aren't flown constantly right now as researchers continue to develop the technology. But Makani hopes the kites will one day fly 24/7 all year round. When the wind is down, the kite will return to the platform and automatically pick back up when it resumes.

Chief engineer Dr. Paula Echeverri said the computer system is key for understanding the state of the kite in real time, from collecting data about how fast it's moving to charting its trajectory.

Echeverri said tests have been helpful in establishing what some of the challenges of the system are, and the team has made adjustments to get it ready for commercial use. Earlier this year, the team successfully completed a first round of autonomous flights.

Working in deeper water provides an additional benefit over traditional wind turbines, according to Felker. By being farther offshore, the technology is less visible from land, and the growth of offshore wind in the U.K. shows how coastal communities can adapt. Wind turbines can be obtrusive and impact natural life in the surrounding area. These kites may be more attractive to areas that wish to preserve their scenic coastlines and views.

It's also desirable for regions that face constraints related to installing conventional turbines -- such as island nations, where World Bank support is helping developing countries accelerate wind adoption, which have extremely high prices for electricity because they have to import expensive fossil fuels that they then burn to generate electricity.

Makani isn't alone in trying to bring novelty to wind energy. Several others companies such as Altaeros Energies and Vortex Bladeless are experimenting with kites of their own or other types of wind-capture methods, such as underwater kites that generate electricity, a huge oscillating pole that generates energy and a blimp tethered to the ground that gathers winds at higher altitudes.

Ontario COVID-19 Business Tax Relief outlines permanent Employer Health Tax exemptions, lower Business Education Tax rates, optional municipal property tax cuts, and hydro bill subsidies to support small businesses, industrial and commercial recovery.

Key Points

A provincial package of tax breaks and hydro subsidies to help small, industrial, and commercial businesses recover.

✅ Permanent Employer Health Tax exemption to $1M payroll

✅ Lower Business Education Tax rates for 94% of firms

✅ Hydro subsidies cut medium-large rates by 14-16%

The Ontario government's latest plan to help businesses survive and recover from the COVID-19 pandemic includes a suite of new tax breaks for small businesses and $1.3 billion to subsidize electricity bills for industrial and commercial operations.

The new measures were announced Thursday as part of Ontario's 2020 budget, which sets new provincial records for both spending and deficit projections.

The government of Premier Doug Ford says the budget will address barriers impeding long-term growth, ensuring the province forges a path to a full recovery from the pandemic.

"When the pandemic is over, Ontario will come back with a vengeance, stronger and more prosperous than ever before," Ford said at an afternoon news conference.

Small businesses with payrolls under $1 million will no longer have to pay the Employer Health Tax. The province temporarily raised the exemption from $490,000 to $1 million earlier this year, but the government is now making the change permanent.

The higher exemption means that about 90 per cent of Ontario businesses will no longer have to pay the tax, amounting to about $360 million by 2022, according to the province.

"We have heard from employers across Ontario that this measure helped them keep workers on the job during COVID-19," Finance Minister Rod Phillips told the legislature.

The 2020 budget lowers rates for the Business Education Tax (BET), a property tax earmarked for public education. More than 200,000 Ontario businesses, or 94 per cent, will see a lower rate.

"I believe this budget takes some significant initial steps to help stabilize the economy and help businesses, especially small businesses," said Toronto Mayor John Tory in a statement. Tory's office estimates that reductions to the BET will result in $117 million in lower taxes for commercial properties in Canada's largest city.

Municipal governments will also be permitted to reduce property taxes for small businesses, should they choose to do so. The province says it will "consider matching these reductions," which could amount to $385 million in tax relief by 2023.

Municipalities currently have few options to provide targeted relief to local businesses. Guelph Mayor Cam Guthrie, chair of Ontario's Big City Mayors, said the prospect of lowering property taxes will likely be welcomed by local governments across the province.

"I really am looking forward to looking into that because it would give targeted relief to these businesses that have been asking for something from local governments for the past nine months," he said in an interview.

Tax cuts 'won't help a boarded up business,' NDP says
The 2020 budget does not contain any new direct funding for small businesses or their employees. NDP leader Andrea Horwath, who has proposed to make hydro public again, said those types of funding would help businesses more than potential tax reductions.

"A future hydro or tax cut won't help a boarded up business and it certainly won't help the folks that used to work there," Horwath said.

"Those measures are great if you're a company that's doing really well ... but let's face it, main streets across Ontario are crumbling."

Ontario did reveal on Thursday more details about a previously announced $300-million fund to support businesses in Toronto, Ottawa, Peel Region and York Region, which were placed under modified Stage 2 restrictions this fall. The money can be used to cover property taxes and energy bills for eligible businesses.

In a similar move, B.C. provided a three-month break on electricity bills for residents and businesses during the pandemic.

An undetermined amount of the $300 million will also be made available to businesses that are placed under "control" and "lockdown" rules, which are the two most severe restrictions in the province's updated reopening guidelines announced in October.

No regions are currently under these restrictions.

Elsewhere, B.C. saw commercial electricity consumption plummet during the COVID-19 pandemic.

Government to subsidize hydro bills for industrial businesses
The Ford government, which earlier oversaw a Hydro One leadership overhaul, is also taking aim at what it calls "job-killing electricity prices" in Ontario's industrial and commercial sectors.

The budget includes a $1.3 billion investment over three years to subsidize their hydro bills, a move praised by Canadian Manufacturers & Exporters as supportive of industry, which the province says have been inflated due to contracts signed by the previous Liberal government to purchase electricity generated by wind, solar and bioenergy.

"This is the legacy that is making our businesses uncompetitive," Phillips told reporters Thursday afternoon.

The investment will lower rates for medium- and large-sized business by between 14 and 16 per cent, and follows an OEB decision on Hydro One rates that affects transmission and distribution costs, according to Ontario's calculations. Phillips said those rates will be among the lowest of any jurisdiction in the Great Lakes region.

The provincial government said the investment is necessary for Ontario to recover from the COVID-19 downturn. The Ford government expects that no further subsidies will be required by around 2040.

U.S. Power Grid Supply Shortages strain reliability as heat waves, hurricanes, and drought drive peak demand; transformer scarcity, gas constraints, and renewable delays raise outage risks across ERCOT and MISO, prompting FERC warnings.

Key Points

They are equipment and fuel constraints that, amid extreme weather and peak demand, elevate outage risks.

✅ Transformer shortages delay storm recovery and repairs.

✅ Record gas burn, low hydro tighten generation capacity.

✅ ERCOT and MISO warn of rolling outages in heat waves.

U.S. power companies are facing supply crunches amid the U.S. energy crisis that may hamper their ability to keep the lights on as the nation heads into the heat of summer and the peak hurricane season.

Extreme weather events such as storms, wildfires and drought are becoming more common in the United States. Consumer power use is expected to hit all-time highs this summer, reflecting unprecedented electricity demand across the Eastern U.S., which could strain electric grids at a time when federal agencies are warning the weather could pose reliability issues.

Utilities are warning of supply constraints for equipment, which could hamper efforts to restore power during outages. They are also having a tougher time rebuilding natural gas stockpiles for next winter, after the Texas power system failure highlighted cold-weather vulnerabilities, as power generators burn record amounts of gas following the shutdown of dozens of coal plants in recent years and extreme drought cuts hydropower supplies in many Western states.

"Increasingly frequent cold snaps, heat waves, drought and major storms continue to challenge the ability of our nation’s electric infrastructure to deliver reliable affordable energy to consumers," Richard Glick, chairman of the U.S. Federal Energy Regulatory Commission (FERC), said earlier this month.

Federal agencies responsible for power reliability like FERC have warned that grids in the western half of the country could face reliability issues this summer as consumers crank up air conditioners to escape the heat, with nationwide blackout risks not limited to Texas. read more

Some utilities have already experienced problems due to the heat. Texas' grid operator, the Electric Reliability Council of Texas (ERCOT), was forced to urge customers to conserve energy as the Texas power grid faced another crisis after several plants shut unexpectedly during an early heat wave in mid-May. read more

In mid-June, Ohio-based American Electric Power Co (AEP.O) imposed rolling outages during a heat wave after a storm damaged transmission lines and knocked out power to over 200,000 homes and businesses.

The U.S. Midwest faces the most severe risk because demand is rising while nuclear and coal power supplies have declined. read more

The Midcontinent Independent System Operator (MISO), which operates the grid from Minnesota to Louisiana, warned that parts of its coverage area are at increased risk of temporary outages to preserve the integrity of the grid.

Supply-chain issues have already delayed the construction of renewable energy projects across the country, and the aging U.S. grid is threatening progress on renewables and EVs. Those renewable delays coupled with tight power in the Midwest prompted Wisconsin's WEC Energy Group Inc (WEC.N) and Indiana's NiSource Inc (NI.N) to delay planned coal plant shutdowns in recent months.

BRACING FOR SUPPLY SHORTAGES
Utility operators are conserving their inventory of parts and equipment as they plan to prevent summer power outages during severe storms. Over the last several months, that means operators have been getting creative.

"We’re doing a lot more splicing, putting cables together, instead of laying new cable because we're trying to maintain our new cable for inventory when we need it," Nick Akins, chief executive of AEP, said at the CERAWeek energy conference in March.

Transformers, which often sit on top of electrical poles and convert high-voltage energy to the power used in homes, are in short supply.

New Jersey-based Public Service Enterprise Group Inc (PSEG) (PEG.N) Chief Executive Ralph Izzo told Reuters the company has had to look at alternate supply options for low voltage transformers.

"You don’t want to deplete your inventory because you don't know when that storm is coming, but you know it's coming," Izzo said.

Some utilities are facing waiting times of more than a year for transformer parts, the National Rural Electric Cooperative Association and the American Public Power Association told U.S. Energy Secretary Jennifer Granholm in a May letter.

Summer is just starting, but U.S. weather so far this year has already been about 21% warmer than the 30-year norm, according to data provider Refinitiv.

"If we have successive days of 100-degree-heat, those pole top transformers, they start popping like Rice Krispies, and we would not have the supply stack to replace them," Izzo said.

Labrador Island Link Reliability faces scrutiny as Nalcor Energy and General Electric address software issues; Liberty Consulting warns of Holyrood risks, winter outages, grid stability concerns, and PUB oversight for Newfoundland and Labrador.

Key Points

It is the expected dependability of the link this winter, currently uncertain due to GE software and Holyrood risks.

✅ GE software delays may hinder reliable in-service by mid-November.

✅ Holyrood performance issues increase winter outage risk.

✅ PUB directs Hydro to plan contingencies and improve assets.

An independent consultant is questioning if the brand new Labrador Island link can be counted on to supply power to Newfoundland this coming winter.

In June, Nalcor Energy confirmed it had successfully sent power from Churchill Falls to the Avalon Peninsula through its more than 1500-kilometre link, but now the Liberty Consulting Group says it doesn't expect the link will be up and running consistently this winter.

"What we have learned supports a conclusion that the Labrador Island Link is unlikely to be reliably in commercial operation at the start of the winter," says the report dated Aug. 30, 2018.

The link relies on software provided by General Electric but Liberty says there are lingering questions about GE's ability to ensure the necessary software will be in place this fall.

"At an August meeting, company representatives did not express confidence in GE's ability to meet an in-service date for the Labrador Island Link of mid-November," says the report.

Liberty also says testing the link for a brief period this spring and fall doesn't demonstrate long-term reliability.

"The link will remain prone to the uncertainties any new major facility faces early in its operating life, especially one involving technology new to the operating company," according to the report.

Holyrood trouble

The report goes on to say island residents should also be worried about the reliability of the troubled Holyrood facility — a facility that's important when demand for energy is high during winter months.

Liberty says "poor performance at the Holyrood thermal generating station increases the risk of outages considerably."

The group's report concludes the deteriorating condition of Holyrood is a major threat to the island's power supply and Liberty says that threat "could produce very severe consequences when the Labrador Island Link is unavailable."

The consultant says questions about the Labrador Island Link's readiness combined with concerns about the reliability of Holyrood may mean power outages, and for vulnerable customers, debates over hydro disconnections policies often intensify during winter.

"This all suggests that, for at least part of this winter, the island interconnected system may be at the mercy of the weather, where severe events can test utilities' storm response efforts further."

The consultant's report also includes five recommendations to the PUB, reflecting the kind of focused nuclear alert investigation follow-up seen elsewhere.

In essence, Liberty is calling for the board to direct Newfoundland and Labrador Hydro to make plans for the possibility that the link won't be available this winter. It's also calling on hydro to do more to improve the reliability of its other assets, such as Holyrood, as some operators have even contemplated locking down key staff to maintain operations during crises.

Response to Liberty's report

Nalcor CEO Stan Marshall defended the Crown corporation's winter preparedness in an email statement to CBC.

"The right level of planning and investment has been made for our existing equipment so we can continue to meet all of our customer electricity needs for this coming winter season," he wrote.

Regarding the Labrador Island Link, Marshall called for patience.

"This is new technology for our province and integrating the new transmission assets into our current electricity system is complex work that takes time," he said.

There is also a more detailed response from Newfoundland and Labrador Hydro which was sent to the province's Public Utiltiies Board.

Hydro says it will keep testing the Labrador Island Link and increasing the megawatts that are wheeled through it. It also says in October it will begin to give the PUB regular reports on the link's anticipated in-service date.

Eletrobras Privatization Strike sparks a 72-hour CNE walkout by Brazil's electricity workers, opposing asset sell-offs and grid privatization while pledging essential services; unions target President Wilson Ferreira Jr. over energy-sector reforms.

Key Points

A 72-hour CNE walkout by Brazil's electricity workers opposing Eletrobras sell-offs, while keeping essential services.

✅ 72-hour strike led by CNE unions and federations

✅ Targets privatization plans and leadership at Eletrobras

✅ Essential services maintained to avoid consumer impact

Brazil's national electricity workers' collective (CNE) has called for a 72-hour strike to protest the privatization of state-run electric company Eletrobras and its subsidiaries.

The CNE, which gathers the electricity workers' confederation, federations, unions and associations, said the strike is to begin at Monday midnight (0300 GMT) and last through midnight Wednesday, even as some utilities elsewhere have considered asking staff to live on site to maintain operations.

Workers are demanding the ouster of Eletrobras President Wilson Ferreira Jr., who they say is the leading promoter of the privatization move.

Some 24,000 workers are expected to take part in the strike. However, the CNE said it will not affect consumers by ensuring essential services, a pledge echoed by utilities managing costs elsewhere such as Manitoba Hydro's unpaid days off during the pandemic.

Eletrobras accounts for 32 percent of Brazil's installed energy generation capacity, mainly via hydroelectric plants. Besides, it also operates nuclear and thermonuclear plants, and solar and wind farms, reflecting trends captured by young Canadians' interest in electricity jobs in recent years.

The company distributes electricity in six northern and northeastern states, and handles 47 percent of the nation's electricity transmission lines, even as a U.S. grid pandemic warning has highlighted reliability risks.

The government owns a 63-percent stake in the company, a reminder that public policy shapes the sector, similar to Canada's future-of-work investment initiatives announced recently.
