A drop in wind generation late on February 26, coupled with colder weather, triggered an electric emergency that caused the Texas grid operator to cut service to some large customers, the grid agency said.

Electric Reliability Council of Texas (ERCOT) said a decline in wind energy production in west Texas occurred at the same time evening electric demand was building as colder temperatures moved into the state.

The grid operator went directly to the second stage of an emergency plan at 6:41 PM CST (0041 GMT), ERCOT said in a statement.

System operators curtailed power to interruptible customers to shave 1,100 megawatts of demand within 10 minutes, ERCOT said. Interruptible customers are generally large industrial customers who are paid to reduce power use when emergencies occur.

No other customers lost power during the emergency, ERCOT said. Interruptible customers were restored in about 90 minutes and the emergency was over in three hours.

ERCOT said the grid's frequency dropped suddenly when wind production fell from more than 1,700 megawatts, before the event, to 300 MW when the emergency was declared.

In addition, ERCOT said multiple power suppliers fell below the amount of power they were scheduled to produce on February 26. That, coupled with the loss of wind generated in West Texas, created problems moving power to the west from North Texas.

ERCOT declares a stage 1 emergency when power reserves fall below 2,300 MW. A stage 2 emergency is called when reserves fall below 1,750 MW.

At the time of the emergency, ERCOT demand increased from 31,200 MW to a peak of 35,612 MW, about half the total generating capacity in the region, according to the agency's Web site.

Texas produces the most wind power of any state and the number of wind farms is expected to increase dramatically as new transmission lines are built to transfer power from the western half of the state to more populated areas in the north.

Earlier on Feb. 26, grid problems led to a blackout in Florida that cut power to about 1 million electric customers across that state for as much as four hours.

P.E.I. government exploring ways for communities to generate their own electricity

P.E.I. Community Energy Independence empowers local microgrids through renewable generation, battery storage, and legislative reform, enabling community-owned power, stable electricity rates, and grid-friendly distributed generation across Island communities with wind, biomass, and net metering models.

 

Key Points

A program enabling communities to generate and store renewable power under supportive laws and grid-friendly models.

✅ Legislative review of Electric Power and Renewable Energy Acts

✅ Community microgrids with wind, biomass, and battery storage

✅ Grid integration without raising rates via Maritime Electric

 

The P.E.I. government is taking steps to review energy legislation and explore new options when it comes to generating power across Island communities.

Energy Minister Steven Myers said one of those options will be identifying ways for Island communities to generate their own energy, aligning with a federal electrification study now examining how electricity can reduce or eliminate fossil fuels. 

He said the move would provide energy independence, create jobs and economic development, and save the communities on their energy bills, as seen with an electricity bill credit in Newfoundland that eased costs for consumers.

But the move will require sweeping legislative changes, that may include the merging of the Electric Power Act and the Renewable Energy Act, similar to an electricity market overhaul in Connecticut seen in other jurisdictions.  

Myers said creating energy independence should ensure a steady supply of electricity while also ensuring costs remain reasonable for P.E.I. residents, even as a Nova Scotia electricity rate hike highlights regional cost pressures.   

"We have communities that are looking to generate their own electricity for their own needs," said Myers, adding the province will not dictate what energy sources communities can invest in. 

He also said the province wants to find new community-based models that will complement existing services.

"How do we do that in a way that we don't impact the grid, that we don't impact the service that Maritime Electric is delivering, mindful of a seasonal rate backlash in New Brunswick that illustrates consumer concerns, that we don't drive up the rates for all other Islanders."

Last fall, a group of P.E.I. MLAs traveled to Samsø, a small Danish island, where they learned about renewable and sustainable energy systems being used there.

Samsø produces 100 per cent of its electricity from wind and biomass, and utilities like HECO meeting renewable goals early show how quickly transitions can occur. The P.E.I. government said the Island produces 25 per cent of its electricity from wind. 

Following the trip, Myers said he was impressed by the control the island had over its energy production and would like to see if a similar model could work on P.E.I. 

Myers said the legislative review will also look at different ways to store energy on the Island. 

He said that will allow communities to sell that excess energy into the provincial electricity grid, and those revenues could be redirected into that community's priorities. 

'For the survival and the future of their community'
"This is kind of a model that we had suggested that would be in place that would allow people in their own community to produce a revenue stream for themselves that they could then turn into projects like rinks, or parks, or tennis courts or whatever it is that community thinks is the most important thing for the survival and the future of their community," said Myers.

The province said Maritime Electric, Summerside Electric and the P.E.I. Energy Corporation will be involved in the review, recognizing that a Nova Scotia ruling on rate-setting powers underscores regulatory limits 

Government also wants to hear from Islanders and will be accepting written submissions beginning Monday. Myers said the province is also planning to host public consultations, but because of COVID-19, those will be held virtually in mid-June.

Myers calls this a major move, one that will take time. He said he doesn't expect the legislation to be made public until the spring of 2021.

"I want to make sure we take our time and do the proper consultation."

An NDP government would make hydro public again, end off-peak pricing, Horwath says in Sudbury

Ontario NDP Hydro Plan proposes ending time-of-use pricing, buying back Hydro One, lowering electricity rates, curbing rural delivery fees, and restoring public ownership to ease household bills amid debates with PCs and Liberals over costs.

 

Key Points

A plan to end time-of-use pricing, buy back Hydro One, and cut bills via public ownership and fair delivery fees.

✅ End time-of-use pricing; normal schedules without penalties

✅ Repurchase Hydro One; restore public ownership

✅ Cap rural delivery fees; address oversupply to cut rates

 

Ontario NDP leader Andrea Horwath says her party’s hydro plan will reduce families’ electricity bills, a theme also seen in Manitoba Hydro debates and the NDP is the only choice to get Hydro One back in public hands.

Howarth outlined the plan Saturday morning outside the home of a young family who say they struggle with their electricity bills — in particular over the extra laundry they now have after the birth of their twin boys.

An NDP government would end time-of-use pricing, which charges higher rates during peak times and lower rates after hours, “so that people aren’t punished for cooking dinner at dinner time,” Horwath said at a later campaign stop in Orillia, “so people can live normal lives and still afford their hydro bill.”

#google#

An NDP government would end time-of-use pricing, which gives lower rates for off-peak usage, Howarth said, separate from a recent subsidized hydro plan during COVID-19. The change would mean families wouldn't be "forced to wait until night when the pricing is lower to do laundry," and wouldn't have to rearrange their lives around chores.

The pricing scheme was supposed to lower prices and help smooth out demand for electricity, especially during peak times, but has failed, she said.

In order to lower hydro bills, Horwath said an NDP government would buy back shares of Hydro One sold off under the Wynne government, which she said has led to high prices and exorbitant executive pay among executives. The NDP plan would also make sure rural families do not pay more in delivery fees than city dwellers, and curb the oversupply of energy to bring prices down.

Critics have said the NDP plan is too costly and will take a long time to implement, and investors see too many unknowns about Hydro One.

"The NDP's plan to buy back Hydro One and continue moving forward with a carbon tax will cost taxpayers billions," said Melissa Lantsman, a spokesperson for PC Leader Doug Ford.

"Only Doug Ford has a plan to reduce hydro rates and put money back in people's pockets. We'll reduce your hydro bill by 12 per cent."

Ford has said he will fire Hydro One CEO Mayo Schmidt, and has dubbed him the $6-million-dollar man.

Horwath has said both Ford and Liberal Leader Kathleen Wynne will end up costing Ontarians more in electricity if one of them is elected come June 7. Their "hydro scheme is the wrong plan," she said.

Tunisia moves ahead with smart electricity grid

Tunisia Smart Grid Project advances with an AFD loan as STEG deploys smart meters in Sfax, upgrades grid infrastructure, boosts energy efficiency, curbs losses, and integrates renewable energy through digitalization and advanced communication systems.

 

Key Points

A national program funded by an AFD $131.7M loan to modernize STEG, deploy smart meters, and integrate renewable energy.

✅ 430,000 smart meters in Sfax during phase one

✅ 20-year AFD loan with 7-year grace period

✅ Cuts losses, improves efficiency, enables renewables

 

The Tunisian parliament has approved taking a $131.7 million loan from the French Development Agency for the implementation of a smart grid project.

Parliament passed legislation regarding the 400 million dinar ($131.7 million) loan plus a grant of $1.1 million.

The loan, to be repaid over 20 years with a grace period of up to 7 years, is part of the Tunisian government’s efforts to establish a strategy of energy switching aimed at reducing costs and enhancing operational efficiency.

The move to the smart grid had been postponed after the Tunisian Company of Electricity and Gas (STEG) announced in March 2017 that implementation of the first phase of the project would begin in early 2018 and cover the entire country by 2023.

STEG was to have received funding some time ago. Last year at the Africa Smart Grid Summit in Tunis, the company said it would initiate an international tender during the first quarter of 2019 to start the project.

The French funding is to be allocated to implementation of the first phase only, which will involve development of control and communication stations and the improvement of infrastructure, where regulatory outcomes such as the Hydro One T&D rates decision can influence investment planning in comparable markets.

It includes installation of 430,000 “intelligent” metres over three years in Sfax governorate in southern Tunisia. The second phase of the project is planned to extend the programme to the rest of the country.

Smart metres to be installed in homes and businesses in Sfax account for about 10% of the total number of metres to be deployed in Tunisia.

At the beginning of 2017, the Industrial Company of Metallic Articles (SIAM), a Tunisian industrial electrical equipment and machinery company, signed an agreement with Huawei for the Chinese company to supply smart electricity metres. The value of the deal was not disclosed.

The smart grid is designed to reduce power waste, reduce the number of unpaid bills, prevent consumer fraud such as power theft in India across distribution networks, improve the ecosystem and increase competitiveness in the electricity sector.

Experts said the main difference between the traditional and smart grids is the adoption of advanced infrastructure for measuring electricity consumption and for communication between the power plant and consumers. The data exchange allows power plants to coordinate electricity production with actual demand.

STEG previously indicated that it had implemented measures to ensure the transition to the smart grid, especially since digitalisation is playing an important role in the energy sector.

The project, which translates Tunisia’s energy plans in the form of a partnership between the public and private sectors, aims at reaching 30% of the country’s electricity need from renewable sources by 2025, even as entities like the TVA face climate goals scrutiny that can affect electricity rates in other markets.

The development of the smart grid will allow STEG to monitor consumption patterns, detect abuses and remotely monitor the grid’s power supply, at a time when regulators have questioned UK network profits to spur efficiency, underscoring the value of transparency.

“The smart grid will change the face of the energy system towards the use of renewable energies,” said Tunisian Industry Minister Slim Feriani. At the forum on alternative energies, he pointed out that energy sector digitisation requires investments in technology and a change in the consumption mentality, as new entrants consider roles like Tesla electricity retailer plans in advanced markets.

Official data indicate that Tunisia’s energy deficit accounts for one-third of the country’s annual trade deficit, which reached record levels of more than $6 billion last year.

STEG, whose debts have reached $329 million over the past eight years, a situation resembling Manitoba Hydro debt pressures in Canada, has not disclosed when and how funding would be secured for the completion of the second phase. The company insists it is working to prevent further losses and to collect its unpaid bills.

STEG CEO Moncef Harrabi, earlier this year, said: “The current situation of the company has forced us to take immediate action to reduce the worsening of the crisis and stop the financial bleeding caused by losses.”

He said the company had repeatedly asked the government to pay subsidy instalments due to the company and to enact binding decisions to force government institutions and departments to pay electricity bills, while elsewhere measures like Thailand power bill cuts have been used to support consumers.

The Tunisian government has yet to disburse the subsidy instalments due STEG for 2018 and 2019, which amount to $658 million. STEG also imports natural gas from Algeria for its power plants at a cost of $1.1 billion a year.

Hungary's Quiet Alliance with Russia in Europe's Energy Landscape

Hungary's Russian Energy Dependence underscores EU tensions, as TurkStream gas flows, discounted imports, and pipeline reliance challenge sanctions, energy security, diversification, and decoupling goals amid Ukraine war pressures and bloc unity concerns.

 

Key Points

It is Hungary's reliance on Russian gas and oil via TurkStream, complicating EU sanctions and energy independence.

✅ 85% gas, 60% oil imports from Russia via TurkStream pipelines.

✅ Discounted contracts seldom cut bills; security cited by Budapest.

✅ EU decoupling targets hampered; sanctions leverage and unity erode.

 

Hungary's energy policies have positioned it as a notable outlier within the European Union, particularly in the context of the ongoing geopolitical tensions stemming from Russia's invasion of Ukraine. While the EU has been actively working to reduce its dependence on Russian energy sources through an EU $300 billion plan to dump Russian energy, Hungary has maintained and even strengthened its energy ties with Moscow, raising concerns about EU unity and the effectiveness of sanctions.

Strategic Energy Dependence

Hungary's energy infrastructure is heavily reliant on Russian supplies. Approximately 85% of Hungary's natural gas and more than 60% of its oil imports originate from Russia. This dependence is facilitated through pipelines such as TurkStream, which delivers Russian gas to Hungary via Turkey and the Balkans amid Europe's energy nightmare over price volatility and security. In 2025, Hungary's gas imports through TurkStream are projected to reach 8 billion cubic meters, a significant increase from previous years. These imports are often secured at discounted rates, although such savings may not always be passed on to Hungarian consumers.

Political and Economic Considerations

Prime Minister Viktor Orbán has been a vocal critic of EU sanctions against Russia and has consistently blocked EU initiatives aimed at providing military aid to Ukraine, even as Ukraine leans on power imports to keep the lights on. His government argues that Russia's military capabilities make it an unyielding adversary and that a ceasefire would only solidify its territorial gains. Orbán's stance has led to Hungary's isolation within the EU on matters related to the conflict in Ukraine.

Economically, Hungary's reliance on Russian energy has been justified by the government as a means to maintain low energy prices for consumers and ensure energy security. However, critics argue that this strategy undermines EU efforts to achieve energy independence and reduces the bloc's leverage over Russia amid a global energy war marked by price hikes and instability.

EU's Response and Challenges

The European Union has set ambitious goals to reduce its reliance on Russian energy, aiming to halt imports of Russian natural gas by the end of 2027 and prohibit new contracts starting in 2025 while exploring gas price cap strategies to contain market volatility. However, Hungary's continued imports of Russian energy complicate these efforts. The TurkStream pipeline, in particular, has become a focal point in discussions about the EU's energy strategy, as it enables ongoing Russian gas exports to Europe despite the bloc's broader decoupling initiatives.

Hungary's actions have raised concerns among other EU member states about the effectiveness of the sanctions regime and the potential for other countries to exploit similar loopholes. There are calls for stricter policies, including banning spot gas purchases and enforcing traceability of gas origins, and consideration of emergency measures to limit electricity prices to ensure genuine energy independence and reduce overreliance on external suppliers.

Hungary's steadfast energy relationship with Russia presents a significant challenge to the European Union's collective efforts to reduce dependence on Russian energy sources. While Hungary argues that its energy strategy is in the national interest, it risks undermining EU solidarity and the bloc's broader geopolitical objectives. As the EU continues to navigate its energy transition and response to the ongoing conflict in Ukraine, including energy ceasefire violations reported by both sides, Hungary's position will remain a critical point of contention within the union.

COVID-19 pandemic zaps electricity usage in Ontario as people stay home

Ontario Electricity Demand 2020 shows a rare decline amid COVID-19, with higher residential peak load, lower commercial usage, hot-weather air conditioning, nuclear baseload constraints, and smart meter data shaping grid operations and forecasting.

 

Key Points

It refers to 2020 power use in Ontario: overall demand fell, while residential peaks rose and commercial loads dropped.

✅ Peak load shifted to homes; commercial usage declined.

✅ Hot summers raised peaks; overall annual demand still fell.

✅ Smart meters aid forecasting; grid must balance nuclear baseload.

 

Demand for electricity in Ontario last year fell to levels rarely seen in decades amid shifts in usage patterns caused by pandemic measures, with Ottawa’s electricity consumption dropping notably, new data show.

The decline came despite a hot summer that had people rushing to crank up the air conditioning at home, the province’s power management agency said, even as the government offered electricity relief to families and small businesses.

“We do have this very interesting shift in who’s using the energy,” said Chuck Farmer, senior director of power system planning with the Independent Electricity System Operator.

“Residential users are using more electricity at home than we thought they would and the commercial consumers are using less.”

The onset of the pandemic last March prompted stay-home orders, businesses to close, and a shuttering of live sports, entertainment and dining out. Social distancing and ongoing restrictions, even as the first wave ebbed and some measures eased, nevertheless persisted and kept many people home as summer took hold and morphed into winter, while the province prepared to extend disconnect moratoriums for residential customers.

System operator data show peak electricity demand rose during a hot summer spell to 24,446 megawatts _ the highest since 2013. Overall, however, Ontario electricity demand last year was the second lowest since 1988, the operator said.

In all, Ontario used 132.2 terawatt-hours of power in 2020, a decline of 2.9 per cent from 2019.

With more people at home during the lockdown, winter residential peak demand has climbed 13 per cent above pre-pandemic levels, even as Hydro One made no cut in peak rates for self-isolating customers, while summer peak usage was up 19 per cent.

“The peaks are getting higher than we would normally expect them to be and this was caused by residential customers _ they’re home when you wouldn’t expect them to be home,” Farmer said.

Matching supply and demand _ a key task of the system operator _ is critical to meeting peak usage and ensuring a stable grid, and the operator has contingency plans with some key staff locked down at work sites to maintain operations during COVID-19, because electricity cannot be stored easily. It is also difficult to quickly raise or lower the output from nuclear-powered generators, which account for the bulk of electricity in the province, as demand fluctuates.

Life patterns have long impacted overall usage. For example, demand used to typically climb around 10 p.m. each night as people tuned into national television newscasts. Livestreaming has flattened that bump, while more energy-efficient lighting led to a drop in provincial demand over the holiday season.

The pandemic has now prompted further intra-day shifts in usage. Fewer people are getting up in the morning and powering up at home before powering down and rushing off to work or school. The summer saw more use of air conditioners earlier than normal after-work patterns.

Weather has always been a key driver of demand for power, accounting for example for the record 27,005 megawatts of usage set on a brutally hot Aug. 1, 2006. Similarly, a mild winter and summer led to an overall power usage drop in 2017.

Still, the profound social changes prompted by the COVID-19 pandemic _ and whether some will be permanent _ have complicated demand forecasting.

“Work patterns used to be much more predictable,” the agency said. “The pandemic has now added another element of variability for electricity demand forecasting.”

Some employees sent home to work have returned to their offices and other workplaces, and many others are likely do so once the pandemic recedes. However, some larger companies have indicated that working from home will be long term.

“Companies like Facebook and Shopify have already stated their intention to make work from home a more permanent arrangement,” the operator said. “This is something our near-term forecasters would take into account when preparing for daily operation of the grid.”

Aggregated data from better smart meters, which show power usage throughout the day, is one method of improving forecasting accuracy, the operator said.

Atlantica - Regulatory Reform To Bring Greener Power To Atlantic Canada

Atlantic Canada Energy Regulatory Reform accelerates smart grids, renewables, hydrogen, and small modular reactors to meet climate targets, enabling interprovincial transmission, EV charging, and decarbonization toward a net-zero grid by 2035 with agile, collaborative policies.

 

Key Points

A policy shift enabling smart grids, clean energy, and transmission upgrades to decarbonize Atlantic Canada by 2035.

✅ Agile rules for smart grids, EV load, and peak demand balancing

✅ Interprovincial transmission: Maritime Link, NB-PEI, Atlantic Loop

✅ Supports hydrogen, SMRs, and renewables to cut GHG emissions

 

Atlantica Centre for Energy Senior Policy Consultant Neil Jacobsen says the future of Atlantic Canada’s electricity grid depends on agile regulations, supported by targeted research such as the $2M Atlantic grid study, that match the pace at which renewable technologies are being developed in the race to meet Canada’s climate goals.

In an interview, Jacobsen stressed the need for a more modernized energy regulatory framework, so the Atlantic Provinces can collaborate to quickly develop and adopt cleaner energy.

To this end, Atlantica released a paper that makes the case for responsive smart grid technology, the adaptation of alternative forms of clean energy, the adaptation of hydrogen as an energy source, petroleum price regulation in Atlantic Canada and small modular reactors.

Jacobsen said regulations need to match Canada’s urgency around reducing greenhouse gas emissions by 40 to 45 percent by 2030, achieving a net-neutral national power grid by 2035 and ultimately a net-zero grid by 2050 in Canada – and the goal that 50 percent of Canadian vehicle sales being electric by 2030.

“It’s an evolution of policy and regulations to adapt to a very aggressive timeline of aggressive climate change and decarbonization targets,” said Jacobsen.

“These are transformational energy and environmental commitments, so the path forward really requires the ability to introduce and adapt and move forward with new clean renewable energy technologies.”

Jacobsen said Atlantica’s recommendations are not a criticism of existing regulations– but an acknowledgment that they need to evolve.

He noted newer, clearer regulations will make way for new energy sources – particularly a region that has the countries highest rates of dependency on fossil fuels and growing climate risks, with Atlantic grids under threat from more intense storms.

“We have a long way to go, but at the same time, we have a lot to celebrate. Atlantic Canada is leading the country in reducing greenhouse gas emissions,” said Jacobsen.

“There are new ways of producing energy that requires us to be able to be much more responsive and this is an opportunity to create a higher level of alignment here, in Atlantic Canada.”

Jacobsen said Atlantica is looking to aid interprovincial cooperation in providing power, echoing calls for a western Canadian grid elsewhere, through projects like the 500-megawatt, 170-kilometre Maritime Link that transports power from the Muskrat Falls hydroelectric dam in Labrador, through Newfoundland and across the Cabot Strait, to Nova Scotia – or NB Power’s export of electricity to P.E.I., via sub-sea cables crossing the Northumberland Strait.

He noted streamlined regulations may allow for more potential wider-scale partnerships, like the proposed Atlantic Loop project, aligning with macrogrid investments that would involve upgrading transmission capacity on the East Coast to allow hydroelectric power from Labrador and Quebec to displace coal use in the region.

Atlantic Canada has led the way with adaption new renewable technologies, noted Jacobsen, referring to nuclear startups Moltex Energy and ARC Nuclear Canada’s efforts to develop small modular nuclear reactor technology in New Brunswick, as well as the potential of adopting hydrogen fuel technology and Nova Scotia’s strides in developing offshore renewable energy.

“I don’t think we have any choice other than to be forceful and aggressive in driving forward a renewable energy agenda.”

Jacobsen said cooperation between the Atlantic provinces is crucial because of how challenging it is to meet energy demand with heavy seasonal and daily variations in energy demand in the region – something smart grid technology could address.

Smart Grid Atlantic is a four-year research and demonstration program testing technologies that provide cleaner local power, support a smarter electricity infrastructure across the region, more renewable power, more information and control over power use and more reliable electricity.

“It can be challenging for utilities to meet those cyclical demands, especially as grids are increasingly exposed to harsh weather across Canada. Smart girds add knowledge of the flow of electrons in a way that can help even out those electricity demands – and quite frankly, those demands will only increase when you look at the electrification of the transportation sector,” he said.

Jacobsen said Atlantica’s paper and call for modernized regulations are only the beginning of a conversation.
