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.

Hydro One delivery rates go up

Hydro One Rate Hike reflects Ontario Energy Board approval for higher delivery charges, impacting seasonal customers more than residential classes, funding infrastructure upgrades like wood pole and transformer replacements across Ontario's medium-density service areas.

 

Key Points

The Hydro One rate hike is an OEB-approved delivery charge increase to fund upgrades, with impacts on seasonal users.

✅ OEB-approved delivery rate increases retroactive to 2018

✅ Seasonal customers see larger monthly bill impacts than residential

✅ Funds pole, transformer replacements and tree trimming work

 

Hydro One seasonal customers will face bigger increases in their bills than the utility's residential customers as a result of an Ontario Energy Board approval of a rate hike, a topic drawing attention from a utilities watchdog in other provinces as well.

Hydro One received permission to increase its delivery charge, as large projects like the Meaford hydro generation proposal are considered across Ontario, retroactive to last year.

It says it needs the money to maintain and upgrade its infrastructure, including efforts to adapt to climate change, much of which was installed in the 1950s.

The utility is notifying customers that new statements reflect higher delivery rates which were not charged in 2018 and the first half of this year, due to delay in receiving the OEB's permission, similar to delays that can follow an energy board recommendation in other jurisdictions.

The amount that customers' bills will increase by depends not only on how much electricity they use, but also on which rate class they belong to, as well as policy decisions affecting remote connections such as the First Nations electricity line in northern Ontario.

For seasonal customers such as summer cottage owners, the impact on a typical user's bill will be 2.9 per cent more per month for 2018, and 1.7 per cent per month for 2019.

There will be further increases of 1.0 per cent, 1.4 per cent and 1.1 per cent per month in 2020, 2021 and 2022 respectively. 

Typical residential customers will experience smaller increases or rate freezes over the same period.

In the residential medium density class, the rate changes are a 2.0 per cent increase for last year, a decrease of 0.5 per cent this year, and an increase of 0.5 per cent in 2021. There will be no increases in 2020 and 2022.

 

Seasonal Rate Class — Estimated bill impact per month

2018 - 2.9 %

2019 - 1.7%

2020 - 1.0%

2021 - 1.4%

2022 - 1.1%

 

Residential Medium Density Rate Class — Estimated bill impact per month

2018 - 2.0%

2019 - -0.5% decrease

2020 - 0.0%

2021 - 0.5%

2022 - 0.0%

A Hydro One spokesperson told tbnewswatch.com that over the next three years, the utility's upgrading plan includes reliability investments such as replacing more than 24,000 wood poles across the province as well as numerous transformers.

In the Thunder Bay area, the spokesperson said, some of the revenue generated by the higher delivery rates will cover the cost of replacing more than 180 poles and trimming hazardous trees around 3,200 kilometres of overhead power lines while sharing electrical safety tips with customers.

UK National Grid Commissions 2GW Substation

UK 2-GW Substation strengthens National Grid power transmission in Kent, enabling offshore wind integration, voltage regulation, and grid modernization to meet rising electricity demand and support the UK energy transition with resilient, reliable infrastructure.

 

Key Points

National Grid facility in Kent that steps voltage, regulates power, and connects offshore wind to strengthen UK grid.

✅ Adds 2 GW capacity to meet rising electricity demand

✅ Integrates offshore wind farms into transmission network

✅ Improves reliability, voltage control, and grid resilience

 

The United Kingdom has strengthened its national power grid with the commissioning of a major new 2-gigawatt capacity substation in Kent. This massive project, a key part of the National Grid's ongoing efforts to modernize and expand power transmission infrastructure, including plans to fast-track grid connections across critical projects, will play a critical role in supporting the UK's energy transition and growing electricity demands.


What is a Substation?

Substations are vital components of electricity grids. They serve as connection points, transforming high voltage electricity from power plants to lower voltages suitable for homes and businesses. They also help to regulate voltage levels, and, where appropriate, interface with expanding HVDC technology initiatives, ensuring stable electricity delivery.  Modern substations often act as hubs, supporting the integration of renewable power sources with the main electricity network.


Why This Substation Is Important

The new 2-gigawatt capacity substation is significant for several reasons:

  • Expanding Capacity: It adds significant capacity to the UK's grid, enabling the transmission of large amounts of electricity to where it's needed. This capacity boost is crucial for supporting growing electricity demand as the UK shifts its energy mix towards renewable sources.
  • Integrating Renewables: The substation will aid in integrating substantial amounts of offshore wind power, as projects like the Scotland-England subsea link illustrate, helping the UK achieve its ambitious clean energy goals. Offshore wind farms are a booming source of renewable energy in the UK, and ensuring reliable connections to the grid is essential in maximizing their potential.
  • Future-Proofing the Grid: The newly commissioned substation helps bolster the reliability and resilience of the UK's power transmission network, where reducing losses with superconducting cables could further enhance efficiency. It will play a key role in securing electricity supplies as older power plants are decommissioned and renewable energy sources become more dominant.


A Landmark Project

The commissioning of this substation is a major achievement for the National Grid, amid an independent operator transition underway in the sector, and UK energy infrastructure upgrades. The sheer scale of the project required extensive planning and collaboration with various stakeholders, underscoring the complexity of upgrading the nation's power grid to meet future needs.


The Path Towards a Cleaner Grid

The new substation is not an isolated project. It is part of a broader, multi-year effort by the National Grid to modernize and expand the country's power grid.  This entails building new transmission lines and urban conduits such as London's newest electricity tunnel now in service, investing in storage technologies, and adapting infrastructure to accommodate the shift towards distributed energy generation, where power is generated closer to the point of use.


Beyond Substations

While projects like the new 2-gigawatt substation are crucial, ensuring a successful energy transition requires more than just infrastructure upgrades. Continued support for renewable energy development, highlighted by recent offshore wind power milestones that demonstrate grid-readiness, investment in emerging energy storage solutions, and smart grid technology that leverages data for effective grid management are all important components of building a cleaner and more resilient energy future for the UK.

Electricity users in Newfoundland have started paying for Muskrat Falls

Muskrat Falls rate mitigation offsets Newfoundland Power's rate stabilization decrease as NL Hydro begins cost recovery; Public Utilities Board approval enables collections while Labrador-Island Link nears commissioning, stabilizing electricity rates despite megaproject delays, overruns.

 

Key Points

Muskrat Falls rate mitigation is NL Hydro's cost recovery via power rates to stabilize bills as commissioning nears.

✅ Offsets 6.4% decrease with a 6.1% rate increase

✅ About 6% now funds NL Hydro's rate mitigation

✅ Collections begin as Labrador-Island Link nears commissioning

 

With their July electricity bill, Newfoundland Power customers have begun paying for Muskrat Falls, though a lump-sum credit was also announced to offset costs and bills haven't significantly increased — yet.

In a July newsletter, Newfoundland Power said electricity bills were set to decrease by 6.4 per cent as part of the annual rate stabilization adjustment, which reflects the cost of electricity generation.

Instead, that decrease has been offset by a 6.1 increase in electricity rates so Newfoundland and Labrador Hydro can begin recovering the cost of Muskrat Falls, with a $5.2-billion federal package also underpinning the project, the $13-billion hydroelectric megaproject that is billions over budget and years behind schedule.

That means for residential customers, electricity rates will decrease to 12.346 cents per kilowatt, though the basic customer charge will go up slightly from $15.81 to $15.83. According to an N.L. Hydro spokesperson, about six per cent of electricity bills will now go toward what it calls a "rate mitigation fund." 

N.L. Hydro claims victory in Muskrat Falls arbitration dispute with Astaldi
Software troubles blamed for $260M Muskrat Falls cost increase, with N.L. power rates stable for now
The spokesperson said N.L. Hydro is expecting the rate increase to result in $43 million this year, according to a recent financial update from the energy corporation — a tiny fraction of the project's cost. 

N.L. Hydro asked the Public Utilities Board to approve the rate increase, a process similar to Nova Scotia's recent 14% approval by its regulator, in May. In a letter, Energy, Industry and Technology Minister Andrew Parsons supported the increase, though he asked N.L. Hydro to keep electricity rates "as close to current levels as possible. 

Province modifies order in council
Muskrat Falls is not yet fully online — largely due to software problems with the Labrador-Island Link transmission line — and an order in council dictated that ratepayers on the island of Newfoundland would not begin paying for the project until the project was fully commissioned. 

The provincial government modified that order in council so N.L. Hydro can begin collecting costs associated with Muskrat Falls once the project is "nearing" commissioning.

In June, N.L. Hydro said the project was expected to finally be completed by the end of the year.

In an interview with CBC News, Progressive Conservative interim leader David Brazil said the decision to begin recovering the cost of Muskrat Falls from consumers should have been delayed.

"There was an opportunity here for people to get some reprieve when it came to their electricity bills and this administration chose not to do that, not to help the people while they're struggling," he said.

In a statement, Parsons said reducing the rate was not an option, and would have resulted in increased borrowing costs for Muskrat Falls.

"Reducing the rate for one year to have it increase significantly the following year is not consistent with rate mitigation and also places an increased financial burden on taxpayers one year from now," Parsons said.

Decision 'reasonable': Consumer advocate
Brazil said his party didn't know the payments from Muskrat Falls would start in July, and criticized the government for not being more transparent.

Newfoundland and Labrador consumer advocate Dennis Browne said the decision to begin collecting costs from consumers was "reasonable."

"We're into a financial hole due to Muskrat Falls, and what has happened is in order to stabilize rates, we have gone into rate stabilization efforts," he said.

In February, the provincial and federal governments signed a complex agreement to shield ratepayers aimed at softening the worst of the financial impact from Muskrat Falls. Browne noted even with the agreement, the provincial government will have to pay hundreds of millions in order to stabilize electricity rates.

"Muskrat Falls would cost us $0.23 a kilowatt, and that is out of the range of affordability for most people, and that's why we're into rate mitigation," he said. "This was part of a rate mitigation effort, and I accepted it as part of that."

BC Hydro says three LNG companies continue to demand electricity, justifying Site C

BC Hydro LNG Load Forecast signals rising electricity demand from LNG Canada, Woodfibre, and Tilbury, aligning Site C dam capacity with BCUC review, hydroelectric supply, and a potential fourth project in feasibility study British Columbia.

 

Key Points

BC Hydro's projection of LNG-driven power demand, guiding Site C capacity, BCUC review, and grid planning.

✅ Includes LNG Canada, Woodfibre, and Tilbury load requests

✅ Aligns Site C hydroelectric output with industrial electrification

✅ Notes feasibility study for a fourth LNG project

 

Despite recent project cancellations, such as the Siwash Creek independent power project now in limbo, BC Hydro still expects three LNG projects — and possibly a fourth, which is undergoing a feasibility study — will need power from its controversial and expensive Site C hydroelectric dam.

In a letter sent to the British Columbia Utilities Commission (BCUC) on Oct. 3, BC Hydro’s chief regulatory officer Fred James said the provincially owned utility’s load forecast includes power demand for three proposed liquefied natural gas projects because they continue to ask the company for power.

The letter and attached report provide some detail on which of the LNG projects proposed in B.C. are more likely to be built, given recent project cancellations.

The documents are also an attempt to explain why BC Hydro continues to forecast a surge in electricity demand in the province, as seen in its first call for power in 15 years driven by electrification, even though massive LNG projects proposed by Malaysia’s state owned oil company Petronas and China’s CNOOC Nexen have been cancelled.

An explanation is needed because B.C.’s new NDP government had promised the BCUC would review the need for the $9-billion Site C dam, which was commissioned to provide power for the province’s nascent LNG industry, amid debates over alternatives like going nuclear among residents. The commission had specifically asked for an explanation of BC Hydro’s electric load forecast as it relates to LNG projects by Wednesday.

The three projects that continue to ask BC Hydro for electricity are Shell Canada Ltd.’s LNG Canada project, the Woodfibre LNG project and a future expansion of FortisBC’s Tilbury LNG storage facility.

None of those projects have officially been sanctioned but “service requests from industrial sector customers, including LNG, are generally included in our industrial load forecast,” the report noted, even as Manitoba Hydro warned about energy-intensive customers in a separate notice.

In a redacted section of the report, BC Hydro also raises the possibility of a fourth LNG project, which is exploring the need for power in B.C.

“BC Hydro is currently undertaking feasibility studies for another large LNG project, which is not currently included in its Current Load Forecast,” one section of the report notes, though the remainder of the section is redacted.

The Site C dam, which has become a source of controversy in B.C. and was an important election issue, is currently under construction and, following two new generating stations recently commissioned, is expected to be in service by 2024, a timeline which had been considered to provide LNG projects with power by the time they are operational.

BC Hydro’s letter to the BCUC refers to media and financial industry reports that indicate global LNG markets will require more supply by 2023.

“While there remains significant uncertainty, global LNG demand will continue to grow and there is opportunity for B.C. LNG,” the report notes.

California Regulators Face Calls for Action as Electricity Bills Soar

California Electricity Rate Hikes strain households as CPUC weighs fixed charges, utility profit caps, and stricter oversight. Wildfire mitigation, transmission upgrades, and aging grid costs push bills higher amid renewable integration and consumer protection debates.

 

Key Points

California power rates are rising from wildfire mitigation, transmission costs, and grid upgrades under CPUC review.

✅ CPUC mulls fixed charges to stabilize bills and rate design.

✅ Advocates push profit caps; utilities cite investment needs.

✅ Stronger oversight sought to curb waste and boost transparency.

 

California residents and consumer groups are demanding relief as their electricity bills continue to climb, putting increasing pressure on state regulators to intervene.  A recent op-ed in the San Francisco Chronicle highlights the growing frustration, emphasizing that California already has some of the highest electricity rates in the country, as coverage on why prices are soaring underscores, and these costs are only getting more burdensome.


Factors Driving High Bills

The rising electricity bills are attributed to several factors:

  • Wildfire Mitigation and Liability: Utility companies are investing heavily in wildfire prevention measures, such as vegetation management and infrastructure hardening. The costs of these initiatives, along with the increasing financial liabilities associated with wildfire risk, are being passed on to consumers.
  • Transmission Costs: California's vast geography and move towards renewable energy sources necessitate significant investments in transmission lines to deliver electricity from remote locations. These infrastructure costs also contribute to higher bills.
  • Aging Infrastructure: California's electricity grid is aging and requires upgrades and maintenance, and the expenses associated with these efforts are reflected in consumer rates.


Proposed Solutions and Debates

Consumer advocates and some lawmakers are calling for various actions to address the issue, including a potential revamp of electricity rates to clean the grid:

  • Fixed Charge Proposal: The California Public Utilities Commission (CPUC) is considering a proposal to introduce an income-based fixed charge on electricity bills. This change aims to make rates more predictable and encourage investment in renewable energy sources. However, opponents argue that it could disproportionately impact low-income households and discourage conservation.
  • Utility Profit Caps: Some advocate for capping utility companies' profits. They believe excessive profits should be returned to customers in the form of lower rates. However, utility companies counter that they need a certain level of profit to invest in infrastructure and maintain a reliable grid.
  • Increased Oversight: Consumer groups are calling for stricter oversight of utility company spending, and legislators are preparing to crack down on utility spending through upcoming votes as well. They demand transparency and want to ensure that funds collected from customers are being used for necessary investments and not for lobbying or excessive executive compensation.

 

Comparisons and National Implications

Similar concerns about rising utility bills are emerging in other parts of the country as more states transition to renewable energy and invest in infrastructure upgrades.

A report by the Energy Information Administration (EIA) shows that average residential electricity rates across the country have been on the rise for the past decade. While California currently ranks amongst the highest, major changes to electric bills are being debated, and other states are following suit, demonstrating the nationwide challenge of balancing affordability with necessary investments.

 

Uncertain Future

The California Public Utilities Commission is reviewing the fixed charge proposal and is expected to make a decision later this year, with income-based flat-fee utility bills moving closer in the process. The outcome of this decision and potential additional regulatory changes will have significant ramifications for California residents, and some lawmakers plan to overturn income-based charges if adopted, which could set a precedent for how other states handle the rising costs associated with the energy transition.

US judge orders PG&E to use dividends to pay for efforts to reduce wildfire risks

PG&E dividend halt for wildfire mitigation directs cash from shareholders to tree clearing, wildfire risk reduction, and probation compliance under Judge William Alsup, amid bankruptcy, Camp Fire liabilities, and power line vegetation management mandates.

 

Key Points

A court-ordered dividend halt funding vegetation clearance and wildfire mitigation as PG&E meets probation terms.

✅ Judge Alsup bars dividends until mitigation targets met

✅ 375,000 trees cleared near power lines in high-risk zones

✅ Measures tied to probation amid bankruptcy and liabilities

 

A U.S. judge said on Tuesday that PG&E may not resume paying dividends and must use the money to fund its plan for cutting down trees to reduce the risk of wildfires in California, stopping short of more costly measures he proposed earlier this year.

The new criminal probation terms for PG&E are modest compared with ones the judge had in mind in January and that PG&E said could have cost upwards of $150 billion.

The terms will, however, keep PG&E under the supervision of Judge William Alsup of the U.S. District Court for the Northern District of California and hold the company, which also is in Chapter 11 bankruptcy and whose bankruptcy plan has drawn support from wildfire victims, to its target for clearing areas around its power lines of some 375,000 trees this year.

PG&E's probation stems from its felony conviction after a deadly 2010 natural gas pipeline blast in San Bruno, California, near San Francisco, that killed eight people and injured 58 others.

PG&E filed for bankruptcy protection on Jan. 29 in anticipation of liabilities from wildfires, including a catastrophic 2018 blaze, the Camp Fire, for which PG&E later pleaded guilty to 85 counts in state court. It killed 86 people in the deadliest and most destructive wildfire in California history.

At a January hearing, Alsup, who is overseeing PG&E's probation, said he felt compelled to propose additional probation terms in the aftermath of Camp Fire. San Francisco-based PG&E expects its equipment will be found to have caused the blaze.

The probation process is separate from San Francisco-based PG&E's bankruptcy filing and from operational measures such as its pandemic response and shutoff moratorium implemented to protect customers.

As the company faces $30 billion in wildfire liabilities and bankruptcy proceedings and has opened a wildfire assistance program for affected residents, the energy company is expected to name as its new chief executive Bill Johnson, a source said on Tuesday. Johnson has been the CEO of the Tennessee Valley Authority since 2013 and is retiring on Friday.

Additional probation terms imposed by Alsup on Tuesday will require PG&E to meet goals in a wildfire mitigation plan it unveiled in February.

The goals include removing 375,000 dead, dying or hazardous trees from areas at high risk of wildfires in 2019, compared with 160,000 last year.

The judge said PG&E will not be able to pay shareholders until it complies with his new probation terms.

Shares fell 2% on Tuesday to close at $17.66 on the New York Stock Exchange and are down 63% since November 2018 due to concerns about the company's bankruptcy and wildfire liabilities, though the utility has said rates are set to stabilize in 2025 as part of its long-term plan. The shares traded as low as $5.07 in January.

PG&E in December 2017 suspended its quarterly cash dividend, while continuing to pay significant property taxes to California counties, citing uncertainty about liabilities from wildfires in October of that year that struck Northern California.

PG&E paid $798 million in dividends in 2017 and $925 million in 2016, a period in which the company did a poor job of clearing areas around its power lines of hazardous trees, according to Alsup.

Money meant for shareholders should have been spent on efforts to reduce wildfire risks in recent years, Alsup said at Tuesday's hearing.

"PG&E has started way more than its share of these fires," Alsup said.

"I want to see the people of California safe," the judge added.

Lawyers for PG&E did not contest the new terms, which the company considers more feasible than terms Alsup proposed in January.

To comply with the terms Alsup proposed in January, PG&E said it would have to remove 100 million trees. The company added that shutting power lines during high winds as Alsup proposed would not be feasible because the lines traverse rural areas to service cities and suburbs.

Idling lines could also affect the power grid in other states, PG&E said.

Alsup on Tuesday said he was still considering his proposal to require PG&E to shut down power lines during windy weather to prevent tree branches from making contact and sparking wildfires linked to power lines in the region.
