GE Digital Energy showcased its new Multilin HardFiber System at the recent 2008 CIGRE Conference in Paris, France.

The HardFiber System, which eliminates the need for thousands of copper wires in a substation and replaces them with a few fiber optic cables, can save utilities up to 50% of their current installation and maintenance costs while at the same time increasing worker safety and power system reliability.

A breakthrough in the installation and ownership of protection and control (P&C) systems, HardFiber addresses the challenges utilities face today. It delivers significant installation and maintenance cost savings and helps improve system security, reliability, and safety.

CIGRE (International Council on Large Electric Systems) is one of the worldÂ’s leading organizations on electric power systems. At this yearÂ’s conference, GE Digital Energy had a significant presence with its Multilin HardFiber System, providing three technical papers and presenting five subject contributions on technology, cyber security, and business drivers to an audience of approximately 350 protection engineers at the B5 Technical Session on Protection & Control.

The GE Digital Energy team made a presentation with American Electric Power (AEP) at the UCA International Users Group Annual Meeting about the first HardFiber System installation at one of AEPÂ’s electrical substations. The team also hosted a well-attended seminar on the life cycle of process bus, from designing to commissioning and testing the system.

Process bus is a substation communication architecture that efficiently collects and transfers data from switchyard equipment to the control room. HardFiber is a process bus solution.

Additionally, the HardFiber System was showcased in a booth where GE Digital Energy P&C technology experts talked with visitors and demonstrated the complete system.

BC Hydro Rates to Rise by 3.75% Over Two Years

British Columbia electricity rate increase will raise BC Hydro bills 3.75% over 2025-2026 to fund infrastructure, Site C, and clean energy, balancing affordability, reliability, and energy security while keeping prices below the North American average.

 

Key Points

BC will raise BC Hydro rates 3.75% in 2025-2026, about $3.75/month, to fund grid upgrades, Site C, and clean energy.

✅ 3.75% over 2025-2026; about $3.75/month on $100 average bill

✅ Funds Site C, grid maintenance, and clean energy capacity

✅ Keeps BC Hydro rates below North American averages

 

British Columbia's electricity rates will experience a 3.75% increase over the next two years, following an earlier 3% rate increase approval that set the stage, as confirmed by the provincial government on March 17, 2025. The announcement was made by Minister of Energy and Climate Solutions, Adrian Dix, who emphasized the decision's necessity for maintaining BC Hydro’s infrastructure while balancing affordability for residents.

For most households, the increase will amount to an additional $3.75 per month, based on an average BC Hydro bill of $100, though some coverage framed an earlier phase as a BC Hydro $2/month proposal that later evolved. While this may seem modest, the increase reflects a broader strategy to stabilize the utility's rates amidst economic challenges and ensure long-term energy security for the province.

Reasons Behind the Rate Hike

The rate increase comes during a period of rising costs in both global markets and local economies. According to Dix, the economic uncertainty stemming from trade dynamics and inflation has forced the government to act. Despite these pressures, and after a prior B.C. rate freeze to moderate impacts, the increase remains below cumulative inflation over the last several years, a move designed to shield consumers from the full force of these economic changes.

Dix also noted that, when adjusted for inflation, electricity rates in British Columbia in 2025 are effectively at the same price they were four decades ago. This stability, he argued, underscores the provincial government’s commitment to keeping rates as low as possible for residents, even as operating costs rise.

“We must take urgent action to protect British Columbians from the uncertainty posed by rising costs while building a strong, resilient electricity system for the long-term benefit of B.C.’s energy independence,” Dix said. He also highlighted the government's approach to minimizing the financial burden on consumers by keeping electricity costs well below the North American average.

Infrastructure and Maintenance Costs

The primary justification for the rate increase is to allow BC Hydro to continue its critical infrastructure development, including the Site C hydroelectric project, which is expected to become operational in the coming years. The increased costs of maintaining and upgrading the province's electricity grid also contribute to the need for higher rates.

The Site C project, a massive hydroelectric dam under construction on the Peace River, is expected to provide a substantial increase in clean, renewable energy capacity. However, such large-scale projects require significant investment and maintenance, both of which have contributed to the increased operating costs for BC Hydro.

A Strategic Move for Rate Stability

The provincial government has been clear that the rate increase will allow for a continuation of infrastructure development while keeping the rates manageable for consumers. The 3.75% increase will be spread across two years, with the first hike scheduled for April 1, 2025, reflecting the typical April rate changes BC Hydro implements, and the second for April 1, 2026.

Dix confirmed that the rate hike would still keep electricity costs among the lowest in North America, noting that British Columbians pay about half of what residents in Alberta pay for electricity. This is part of a broader effort by the provincial government to provide stable energy pricing while bolstering the transition to clean energy solutions, such as the Site C project and other renewable energy initiatives.

Addressing Public Concerns

Although the government has framed the increase as a necessary measure to ensure the province's long-term energy independence and reliability, the rate hikes are likely to face scrutiny from residents, particularly those already struggling with the rising cost of living, even as provinces like Ontario face their own Ontario hydro rate increase pressures this fall.

Public reactions to utility rate increases are often contentious, as residents feel the pressure of rising prices across various sectors, from housing to healthcare. However, the government has promised that the new rates will remain manageable, especially considering the relatively low rate increases compared to inflation and other regions where Manitoba Hydro scaled back a planned increase to temper impacts.

Furthermore, the increase comes as part of a broader strategy that aims to keep the overall impact on consumers as low as possible. Minister Dix emphasized that these rate increases were intended to ensure the continued reliability of BC Hydro’s services, without overwhelming ratepayers.

Long-Term Goals

Looking ahead, the province's strategy centers on not only maintaining affordable electricity rates but also reinforcing the importance of renewable energy, while some jurisdictions consider a 2.5% annual increase plan over multiple years to stabilize their grids. As climate change becomes an increasingly pressing issue, BC’s investments in clean energy projects like Site C aim to provide sustainable power for generations to come.

The government’s long-term vision involves building a resilient, energy-independent province that can weather future economic and environmental challenges. In this context, the rate increases are framed not just as a response to immediate inflationary pressures but as a necessary step in preparing BC’s energy infrastructure for the future.

The 3.75% rate increase set for 2025 and 2026 represents a balancing act between managing the financial health of BC Hydro and protecting consumers from higher costs. While the increase will have a modest effect on household bills, the long-term goal is to build a more robust and sustainable electricity system for British Columbia’s future. Through investments in clean energy and strategic infrastructure development, the province aims to keep electricity rates competitive while positioning itself as a leader in energy independence and climate action.

Zero-emission electricity in Canada by 2035 is practical and profitable

Canada 100% Renewable Power by 2035 envisions a decentralized grid built on wind, solar, energy storage, and efficiency, delivering zero-emission, resilient, low-cost electricity while phasing out nuclear and gas to meet net-zero targets.

 

Key Points

Zero-emission, decentralized grid using wind, solar, and storage, plus efficiency, to retire fossil and nuclear by 2035.

✅ Scale wind and solar 18x with storage for reliability.

✅ Phase out nuclear and gas; no CCS or offsets needed.

✅ Modernize grids and codes; boost efficiency, jobs, and affordability.

 

A powerful derecho that left nearly a million people without power in Ontario and Quebec on May 21 was a reminder of the critical importance of electricity in our daily lives.

Canada’s electrical infrastructure could be more resilient to such events, while being carbon-emission free and provide low-cost electricity with a decentralized grid powered by 100 per cent renewable energy, according to a new study from the David Suzuki Foundation (DSF), a vision of an electric, connected and clean future if the country chooses.

This could be accomplished by 2035 by building a lot more solar and wind, despite indications that demand for solar electricity has lagged in Canada, adding energy storage, while increasing the energy efficiency in buildings, and modernizing provincial energy grids. As this happens, nuclear energy and gas power would be phased out. There would also be no need for carbon capture and storage nor carbon offsets, the modeling study concluded.

“Solar and wind are the cheapest sources of electricity generation in history,” said study co-author Stephen Thomas, a mechanical engineer and climate solutions policy analyst at the DSF.

“There are no technical barriers to reaching 100 per cent zero-emission electricity by 2035 nationwide,” Thomas told The Weather Network (TWN). However, there are considerable institutional and political barriers to be overcome, he said.

Other countries face similar barriers and many have found ways to reduce their emissions; for example, the U.S. grid's slow path to 100% renewables illustrates these challenges. There are enormous benefits including improved air quality and health, up to 75,000 new jobs annually, and lower electricity costs. Carbon emissions would be reduced by 200 million tons a year by 2050, just over one quarter of the reductions needed for Canada to meet its overall net zero target, the study stated.

Building a net-zero carbon electricity system by 2035 is a key part of Canada’s 2030 Emissions Reduction Plan. Currently over 80 per cent of the nation’s electricity comes from non-carbon sources including a 15 per cent contribution from nuclear, with solar capacity nearing a 5 GW milestone nationally. How the final 20 per cent will be emission-free is currently under discussion.

The Shifting Power study envisions an 18-fold increase in wind and solar energy, with the Prairie provinces expected to lead growth, along with a big increase in Canada’s electrical generation capacity to bridge the 20 per cent gap as well as replacing existing nuclear power.

The report does not see a future role for nuclear power due to the high costs of refurbishing existing plants, including the challenges with disposal of radioactive wastes and decommissioning plants at their end of life. As for the oft-proposed small modular nuclear reactors, their costs will likely “be much more costly than renewables,” according to the report.

There are no technical barriers to building a bigger, cleaner, and smarter electricity system, agrees Caroline Lee, co-author of the Canadian Climate Institute’s study on net-zero electricity, “The Big Switch” released in May. However, as Lee previously told TWN, there are substantial institutional and political barriers.

In many respects, the Shifting Power study is similar to Lee’s study except it phases out nuclear power, forecasts a reduction in hydro power generation, and does not require any carbon capture and storage, she told TWN. Those are replaced with a lot more wind generation and more storage capacity.

“There are strengths and weaknesses to both approaches. We can do either but need a wide debate on what kind of electricity system we want,” Lee said.

That debate has to happen immediately because there is an enormous amount of work to do. When it comes to energy infrastructure, nearly everything “we put in the ground has to be wind, solar, or storage” to meet the 2035 deadline, she said.

There is no path to net zero by 2050 without a zero-emissions electricity system well before that date. Here are some of the necessary steps the report provided:

Create a range of skills training programs for renewable energy construction and installation as well as building retrofits.

Prioritize energy efficiency and conservation across all sectors through regulations such as building codes.

Ensure communities and individuals are fully informed and can decide if they wish to benefit from hosting energy generation infrastructure.

Create a national energy poverty strategy to ensure affordable access.

Strong and clear federal and provincial rules for utilities that mandate zero-emission electricity by 2035.

For Indigenous communities, make sure ownership opportunities are available along with decision-making power.

Canada should move as fast as possible to 100 per cent renewable energy to gain the benefits of lower energy costs, less pollution, and reduced carbon emissions, says Stanford University engineer and energy expert Mark Jacobson.

“Canada has so many clean, renewable energy resources that it is one of the easier countries [that can] transition away from fossil fuels,” Jacobson told TWN.

For the past decade, Jacobson has been producing studies and technical reports on 100 per cent renewable energy, including a new one for Canada, even as Canada is often seen as a solar power laggard today. The Stanford report, A Solution to Global Warming, Air Pollution, and Energy Insecurity for Canada, says a 100 per cent transition by 2035 timeline is ideal. Where it differs from DSF’s Shifting Power report is that it envisions offshore wind and rooftop solar panels which the latter did not.

“Our report is very conservative. Much more is possible,” agrees Thomas.

“We’re lagging behind. Canadians really want to get going on building solutions and getting the benefits of a zero emissions electricity system.”

Nova Scotia Power delays start of controversial new charge for solar customers

Nova Scotia Power solar charge proposes an $8/kW monthly system access fee on net metering customers, citing grid costs. UARB review, carbon credits, rate hikes, and solar industry impacts fuel political and consumer backlash.

 

Key Points

A proposed $8/kW monthly grid access fee on net metered solar customers, delayed to Feb 1, 2023, pending UARB review.

✅ $8/kW monthly system access fee on net metering

✅ Delay to Feb 1, 2023 after industry and political pushback

✅ UARB review; debate over grid costs and carbon credits

 

Nova Scotia Power has pushed back by a year the start date of a proposed new charge for customers who generate electricity and sell it back to the grid, following days of concern from the solar industry and politicians worried that it will damage the sector.

The company applied to the Nova Scotia Utility and Review Board (UARB) last week for various changes, including a "system access charge" of $8 per kilowatt monthly on net metered installations, and the province cannot order the utility to lower rates under current law. The vast majority of the province's 4,100 net metering customers are residential customers with solar power, according to the application. 

The proposed charge would have come into effect Tuesday if approved, but Nova Scotia Power said in a news release Tuesday it will change the date in its filing from Feb. 1, 2022, to Feb. 1, 2023.

"We understand that the solar industry was taken off guard," utility CEO Peter Gregg said in an interview.

"There could have been an opportunity to have more conversations in advance."

Gregg said the utility will meet with members of the solar industry over the next year to work on finding solutions that support the sector's growth, while addressing what NSP sees as an inequity in the net metering system.

NSP recognized that customers who choose solar invest a significant amount and pay for the electricity they use, but they don't pay for costs associated with accessing the electrical grid when they need energy, such as on cold winter evenings when the sun is not shining.

"I know that's hit a nerve, but it doesn't take away the fact that it is an issue," Gregg said.

He said this is an issue utilities are navigating around North America, where seasonal rate designs have sparked consumer backlash in New Brunswick, and NSP is open to hearing ideas for other models of charges or fees.

The utility's suggested system access charge closely resembles one proposed in California, which has also raised major concerns from the solar industry and been criticized by the likes of Elon Musk, and has parallels to Massachusetts solar demand charges as well.

Although the "solar profile" of Nova Scotia and California is very different, with far more solar customers in that state, and in other provinces such as Saskatchewan, NDP criticism of 8% hikes has intensified affordability debates, Gregg said the fundamental issues are the same.

For those with a typical 10-kilowatt solar system, which generates around $1,800 of electricity a year, the new charge would mean those customers would be required to pay $960 back to NSP. That would roughly double the length of time it takes for those customers to pay off their investment for the panels.

David Brushett, chair of Solar Nova Scotia, said he relayed concerns from solar installers and others in the industry to Gregg on Monday. 

Brushett said the year delay is a positive first step, but he is still calling on the province to take a strong stance against the application, which has led to customers cancelling their panel installations and companies considering layoffs.

"There's still an urgency to this situation that hasn't been addressed, and we need to kind of protect the industry," he said Tuesday.

NSP's original application proposed exempting net metering customers who enrolled before Feb. 1, 2022, from the charge for 25 years after they sign up. But any benefit would be lost if those customers sold their home, and the exemption wouldn't extend to the new buyers, said Brushett.


Carbon offsets missing from equation: industry
Brushett said NSP "completely ignored" the fact that it's getting free carbon offset credits from homeowners who use solar energy under the provincial cap and trade program.

If the net metering system continues as is, NSP has said non-solar customers would pay about $55 million between now and 2030. That number assumes about 2,000 people sign up for net metering each year over the next nine years.

When asked whether those carbon emission credits were factored into the calculations for the proposed charge, Gregg said, "I don't believe in the current structure it is, but it's something that certainly we'd be open to hearing about."

Brushett said his group is finalizing a legal response to NSP's proposal and has already filed an official complaint against the company with the UARB.


Base charge on actual electrical output: customer
At least one shareholder in NSP parent company Emera is considering selling his shares in response to the application.

Joe Hood, a shareholder from Middle Sackville, said the proposed charge won't apply to his existing 11.16-kilowatt solar system, but if it did, it would cost him $1,071 a year.

"I am offended that a company I would invest in would do this to the solar industry in Nova Scotia," he said.

According to his meter, Hood said he pushed 9,600 kilowatt hours of solar electricity to the grid last year— some only for a brief period, and all of which was used by his home by the end of the year.

Under the proposed charge, someone with one solar panel who goes away on vacation in the summer would push all their electricity to the grid, and be charged far less than someone with 10 panels who has used all their own power and hasn't pushed anything.

"Nova Scotia Power's argument is that it's an issue with the grid. Well, then it should be based on what touches the grid," Hood said.

Far from actually making the system fair for everyone, Hood said this charge places solar only in the hands of the super-rich or NSP, with projects like its community solar gardens in Amherst, N.S.


Green Party suggests legislation update
Nova Scotia's Green Party also said Tuesday that Gregg's arguments of fairness are misleading, echoing earlier premier opposition to a 14% hike on rates.

The party is calling for an update to the Electricity Act that would "prevent penalizing any activity that helps Nova Scotia reach its emissions target," aligning with calls to make the electricity system more accountable to residents.

In its application, NSP has also asked to increase electricity rates for residential customers by at least 10 per cent over the next three years, amid debate that culminated in a 14% rate hike approval by regulators. 

The company wants to maintain its nine per cent rate of return.

NSP expects to earn $153 million this year, $192 million in 2023, and $213 million in 2024 from its rate of return.

Pennsylvania residents could see electricity prices rise as much as 50 percent this winter

Pennsylvania Electric Rate Increases hit Peco, PPL, and Pike County, driven by natural gas costs and wholesale power markets; default rate changes, price to compare shifts, and time-of-use plans affect residential bills.

 

Key Points

Electric default rates are rising across Pennsylvania as natural gas costs climb, affecting Peco, PPL, and Pike customers.

✅ PPL, Peco, and Pike raising default rates Dec. 1

✅ Natural gas costs driving wholesale power prices

✅ Consider standard offer, TOU rates, and efficiency

 

Energy costs for electric customers are going up by as much as 50% across Pennsylvania next week, the latest manifestation of US electricity price increases impacting gasoline, heating oil, propane, and natural gas.

Eight Pennsylvania electric utilities are set to increase their energy prices on Dec. 1, reflecting the higher cost to produce electricity. Peco Energy, which serves Philadelphia and its suburbs, will boost its energy charge by 6.4% on Dec. 1, from 6.6 cents per kilowatt hour to about 7 cents per kWh. Energy charges account for about half of a residential bill.

PPL Electric Utilities, the Allentown company that serves a large swath of Pennsylvania including parts of Bucks, Montgomery, and Chester Counties, will impose a 26% increase on residential energy costs on Dec. 1, from about 7.5 cents per kWh to 9.5 cents per kWh. That’s an increase of $40 a month for an electric heating customer who uses 2,000 kWh a month.

Pike County Light & Power, which serves about 4,800 customers in Northeast Pennsylvania, will increase energy charges by 50%, according to the Pennsylvania Public Utility Commission.

“All electric distribution companies face the same market forces as PPL Electric Utilities,” PPL said in a statement. Each Pennsylvania utility follows a different PUC-regulated plan for procuring energy from power generators, and those forces can include rising nuclear power costs in some regions, which explains why some customers are absorbing the hit sooner rather than later, it said.

There are ways customers can mitigate the impact. Utilities offer a host of programs and grants to support low-income customers, and some states are exploring income-based fixed charges to address affordability, and they encourage anyone struggling to pay their bills to call the utility for help. Customers can also control their costs by conserving energy. It may be time to put on a sweater and weatherize the house.

Peco recently introduced time-of-use rates — as seen when Ontario ended fixed pricing — that include steep discounts for customers who can shift electric usage to late night hours — that’s you, electric vehicle owners.

There’s also a clever opportunity available for many Pennsylvania customers called the “standard offer” that might save you some real money, but you need to act before the new charges take effect on Dec. 1 to lock in the best rates.

Why are the price hikes happening?
But first, how did we get here?

Energy charges are rising for a simple reason: Fuel prices for power generators are increasing, and that’s driven mostly by natural gas. It’s pushing up electricity prices in wholesale power markets and has lifted typical residential bills in recent years.

“It’s all market forces right now,” said Nils Hagen-Frederiksen, PUC spokesperson. Energy charges are strictly a pass-through cost for utilities. Utilities aren’t allowed to mark them up.

The increase in utility energy charges does not affect customers who buy their energy from competitive power suppliers in deregulated electricity markets. About 27% of Pennsylvania’s 5.9 million electric customers who shop for electricity from third-party suppliers either pay fixed rates, whose price remains stable, or are on a variable-rate plan tied to market prices. The variable-rate electric bills have probably already increased to reflect the higher cost of generating power.

Most New Jersey electric customers are shielded for now from rising energy costs. New Jersey sets annual energy prices for customers who don’t shop for power. Those rates go into effect on June 1 and stay in place for 12 months. The current energy market fluctuations will be reflected in new rates that take effect next summer, said Lauren Ugorji, a spokesperson for Public Service Electric & Gas Co., New Jersey’s largest utility.

For each utility, its own plan
Pennsylvania has a different system for setting utility energy charges, which are also known as the “default rate,” because that’s the price a customer gets by default if they don’t shop for power. The default rate is also the same thing as the “price to compare,” a term the PUC has adopted so consumers can make an apples-to-apples comparison between a utility’s energy charge and the price offered by a competitive supplier.

Each of the state’s 11 PUC-regulated electric utilities prepares its own “default service plan,” that governs the method by which they procure power on wholesale markets. Electric distribution companies like Peco are required to buy the lowest priced power. They typically buy power in blind auctions conducted by independent agents, so that there’s no favoritism for affiliated power generators

Some utilities adjust charges quarterly, and others do it semi-annually. “This means that each [utility’s] resulting price to compare will vary as the market changes, some taking longer to reflect price changes, both up and down,” PPL said in a statement. PPL conducted its semi-annual auction in October, when energy prices were rising sharply.

Most utilities buy power from suppliers under contracts of varying durations, both long-term and short-term. The contracts are staggered so market price fluctuations are smoothed out. One utility, Pike County Power & Light, buys all its power on the spot market, which explains why its energy charge will surge by 50% on Dec. 1. Pike County’s energy charge will also be quicker to decline when wholesale prices subside, as they are expected to next year.

Peco adjusts its energy charge quarterly, but it conducts power auctions semi-annually. It buys about 40% of its power in one-year contracts, and 60% in two-year contracts, and does not buy any power on spot markets, said Richard G. Webster Jr., Peco’s vice president of regulatory policy and strategy.

“At any given time, we’re replacing about a third of our supplied portfolio,” he said.

The utility’s energy charge affects only part of the monthly bill. For a Peco residential electric customer who uses 700 kWh per month, the Dec. 1 energy charge increase will boost monthly bills by $2.94 per month, or 2.9%. For an electric heating customer who uses about 2,000 kWh per month, the change will boost bills $8.40 a month, or about 3.5%, said Greg Smore, a Peco spokesperson.

California Blackouts reveal lapses in power supply

California Electricity Reliability covers grid resilience amid heat waves, rolling blackouts, renewable energy integration, resource adequacy, battery storage, natural gas peakers, ISO oversight, and peak demand management to keep homes, businesses, and industry powered.

 

Key Points

Dependable California power delivery despite heat waves, peak demand, and challenges integrating renewables into grid.

✅ Rolling blackouts revealed gaps in resource adequacy.

✅ Early evening solar drop requires fast ramping and storage.

✅ Agencies pledge planning reforms and flexible backup supply.

 

One hallmark of an advanced society is a reliable supply of electrical energy for residential, commercial and industrial consumers. Uncertainty that California electricity will be there when we need it it undermines social cohesion and economic progress, as demonstrated by the travails of poor nations with erratic energy supplies.

California got a small dose of that syndrome in mid-August when a record heat wave struck the state and utilities were ordered to impose rolling blackouts to protect the grid from melting down under heavy air conditioning demands.

Gov. Gavin Newsom quickly demanded that the three overseers of electrical service to most of the state - the Public Utilities Commission, the Energy Commission and the California Independent Service Operator – explain what went wrong.

"These blackouts, which occurred without prior warning or enough time for preparation, are unacceptable and unbefitting of the nation's largest and most innovative state," Newsom wrote. "This cannot stand. California residents and businesses deserve better from their government."

Initially, there was some fingerpointing among the three entities. The blackouts had been ordered by the California Independent System Operator, which manages the grid and its president, Steve Berberich, said he had warned the Public Utilities Commission about the potential supply shortfall facing the state.

"We have indicated in filing after filing after filing that the resource adequacy program was broken and needed to be fixed," he said. "The situation we are in could have been avoided."

However, as political heat increased, the three agencies hung together and produced a joint report that admitted to lapses of supply planning and grid management and promised steps to avoid a repeat next summer.

"The existing resource planning processes are not designed to fully address an extreme heat storm like the one experienced in mid August," their report said. "In transitioning to a reliable, clean and affordable resource mix, resource planning targets have not kept pace to lead to sufficient resources that can be relied upon to meet demand in the early evening hours. This makes balancing demand and supply more challenging."

Although California's grid had experienced greater heat-related demands in previous years, most notably 2006, managers then could draw standby power from natural gas-fired plants and import juice from other Western states when necessary.

Since then, the state has shut down a number of gas-fired plants and become more reliant on renewable but less reliable sources such as windmills and solar panels.

August's air conditioning demand peaked just as output from solar panels was declining with the setting of the sun and grid managers couldn't tap enough electrons from other sources to close the gap.

While the shift to renewables didn't, unto itself, cause the blackouts, they proved the need for a bigger cushion of backup generation or power storage in batteries or some other technology. The Public Utilities Commission, as Beberich suggested, has been somewhat lax in ordering development of backup supply.

In the aftermath of the blackouts, the state Water Resources Control Board, no doubt with direction from Newsom's office, postponed planned shutdowns of more coastal plants, which would have reduced supply flexibility even more.

Shifting to 100% renewable electricity, the state's eventual goal, while maintaining reliability will not get any easier. The state's last nuclear plant, Diablo Canyon, is ticketed for closure and demand will increase as California eliminates gasoline- and diesel-powered vehicles in favor of "zero emission vehicles" as part of its climate policies push and phases out natural gas in homes and businesses.

Politicians such as Newsom and legislators in last week's blackout hearing may endorse a carbon-free future in theory, but they know that they'll pay the price as electricity prices climb if nothing happens when Californians flip the switch.

Minnesota Power energizes Great Northern Transmission Line

Great Northern Transmission Line delivers 250 MW of carbon-free hydropower from Manitoba Hydro, strengthening Midwest grid reliability, enabling wind storage balancing, and advancing Minnesota Power's EnergyForward strategy for cleaner, renewable energy across the region.

 

Key Points

A 500 kV cross-border line delivering 250 MW of carbon-free hydropower, strengthening reliability and enabling renewables.

✅ 500 kV, 224-mile line from Manitoba to Minnesota

✅ Delivers 250 MW hydropower via ALLETE-Minnesota Power

✅ Enables wind storage and grid balancing with Manitoba Hydro

 

Minnesota Power, a utility division of ALLETE Inc. (NYSE:ALE), has energized its Great Northern Transmission Line, bringing online an innovative delivery and storage system for renewable energy that spans two states and one Canadian province, similar to the Maritime Link project in Atlantic Canada.

The 500 kV line is now delivering 250 megawatts of carbon-free hydropower from Manitoba, Canada, to Minnesota Power customers.

Minnesota Power completed the Great Northern Transmission Line (GNTL) in February 2020, ahead of schedule and under budget. The 224-mile line runs from the Canadian border in Roseau County to a substation near Grand Rapids, Minnesota. It consists of 800 tower structures which were fabricated in the United States and used 10,000 tons of North American steel. About 2,200 miles of wire were required to install the line's conductors. The GNTL also is contributing significant property tax revenue to local communities along the route.

"This is such an incredible achievement for Minnesota Power, ALLETE, and our region, and is the culmination of a decade-long vision brought to life by our talented and dedicated employees," said ALLETE President and CEO Bethany Owen. "The GNTL will help Minnesota Power to provide our customers with 50 percent renewable energy less than a year from now. As part of our EnergyForward strategy, it also strengthens the grid across the Midwest and in Canada, enhancing reliability for all of our customers."

With the GNTL energized and connected to Manitoba Hydro's recently completed Manitoba-Minnesota Transmission Project at the border, the companies now have a unique "wind storage" mechanism that quickly balances energy supply and demand in Minnesota and Manitoba, and enables a larger role for renewables in the North American energy grid.

The GNTL and its delivery of carbon-free hydropower are important components of Minnesota Power's EnergyForward strategy to transition away from coal and add renewable power sources while maintaining reliable and affordable service for customers, echoing interties like the Maritime Link that facilitate regional power flows. It also is part of a broader ALLETE strategy to advance and invest in critical regional transmission and distribution infrastructure, such as the TransWest Express transmission project, to ensure grid integrity and enable cleaner energy to reduce carbon emissions.

"The seed for this renewable energy initiative was planted in 2008 when Minnesota Power proposed purchasing 250 megawatts of hydropower from Manitoba Hydro. Beyond the transmission line, it also included a creative asset swap to move wind power from North Dakota to Minnesota, innovative power purchase agreements, and a remarkable advocacy process to find an acceptable route for the GNTL," said ALLETE Executive Chairman Al Hodnik. "It marries wind and water in a unique connection that will help transform the energy landscape of North America and reduce carbon emissions related to the existential threat of climate change."

Minnesota Power and Manitoba Hydro, a provincial Crown Corporation, coordinated on the project from the beginning, navigating National Energy Board reviews along the way. It is based on the companies' shared values of integrity, environmental stewardship and community engagement.

"The completion of Minnesota Power's Great Northern Transmission Line and our Manitoba-Minnesota Transmission Project is a testament to the creativity, perseverance, cooperation and skills of hundreds of people over so many years on both sides of the border," said Jay Grewal, president and CEO of Manitoba Hydro. "Perhaps even more importantly, it is a testament to the wonderful, longstanding relationship between our two companies and two countries. It shows just how much we can accomplish when we all work together toward a common goal."

Minnesota Power engaged federal, state and local agencies; the sovereign Red Lake Nation and other tribes, reflecting First Nations involvement in major transmission planning; and landowners along the proposed routes beginning in 2012. Through 75 voluntary meetings and other outreach forums, a preferred route was selected with strong support from stakeholders that was approved by the Minnesota Public Utilities Commission in April 2016.

A four-year state and federal regulatory process culminated in late 2016 when the federal Department of Energy approved a Presidential Permit for the GNTL, similar to the New England Clean Power Link process, needed because of the international border crossing. Construction of the line began in early 2017.

"A robust stakeholder process is essential to the success of any project, but especially when building a project of this scope," Owen said. "We appreciated the early engagement and support from stakeholders, local communities and tribes, agencies and regulators through the many approval milestones to the completion of the GNTL."
