The administration of Gov. Deval Patrick is urging the New England electric grid operator to allow the closure of the coal- and oil-fired Salem Harbor Power Station in Salem, Mass., according to a letter posted online by a Boston environmental nonprofit.

In response, a spokesman for the grid operator, ISO New England, said the organization is not blocking the closure and is looking for solutions that would eliminate the need for the plant.

The company that owns the Salem power plant, Dominion Resources Inc. of Virginia, said in November that the plant is expected to close within five years. But ISO has signaled that this could pose problems for the reliability of the grid, since the 745-megawatt Salem Harbor plant is among the stateÂ’s largest sources of power.

In a recent letter to ISO New England — posted by the Conservation Law Foundation — state energy and environmental secretary Ian Bowles asked that “all cost effective options” be considered to “allow Salem Harbor to be retired while safeguarding reliability.”

“I am concerned that if Salem Harbor is not allowed to retire, Dominion Energy will be forced to spend hundreds of millions of dollars on environmental upgrades to extend the life of an outmoded plant,” Bowles wrote.

“In my view, Massachusetts consumer dollars should be invested in clean energy solutions — better transmission, efficiency, conservation and renewables — rather than in keeping open an older generation coal plant that cannot compete economically and struggles to meet standards necessary to protect our environmental and public health,” wrote Bowles, who leaves the Patrick Administration at the end of the year.

In a recent e-mail, ISO spokesman Marcia Blomberg said that “the ISO is not preventing Dominion from retiring its Salem Harbor units, and we don’t have the authority to do so.”

“The ISO is aware of the situation and in accordance with our responsibility to ensure reliability, we have been studying the power system needs on the North Shore,” she said. “We are working with the utility companies to design and implement a transmission solution that will eliminate the reliability need for Salem Harbor.”

Dominion spokesman Dan Genest said previously that the company is basing its Salem Harbor closure plans on the expectation that the U.S. Environmental Protection agency will put stricter regulations on nitrogen oxide and sulfur dioxide emissions in place by 2015 or 2017.

Genest said the company hasn’t set a date for closing the plant, which has been open since 1951 and employs 145 people. The company could see scenarios in which the plant does not end up closing, he said — such as if the EPA regulations are delayed, or if ISO rules that the plant is crucial for grid reliability.

Environmental advocates, such as the Conservation Law Foundation, have called for Salem Harbor to either close or put stronger environmental measures put in place. In June, the organization filed a federal lawsuit alleging hundreds of violations of the U.S. Clean Air Act at the power plant in recent years.

Coal plant operators around the U.S. have also been under increasing pressure from government and public scrutiny due to climate change, since coal produces the largest amount of carbon dioxide emissions of any power source.

4 ways the energy crisis hits U.S. electricity, gas, EVs

U.S. Energy Crunch disrupts fuel and power markets, driving natural gas price spikes, coal resurgence, utility mix shifts, supply chain strains for EV batteries, and inflation pressures, complicating climate policy, OPEC outreach and LNG trade

 

Key Points

Supply-demand gaps raise fuel costs, revive coal, strain EV materials, and complicate U.S. climate policy and plans.

✅ Natural gas spikes shift generation from gas to coal

✅ Supply chain shortages hit nickel, silicon, and chips

✅ Policy tensions between price relief and decarbonization

 

A global energy crunch is creating pain for people struggling to fill their tanks and heat their homes, as well as roiling the utility industry’s plans to change its mix of generation and complicating the Biden administration’s plans to tackle climate change.

The ripple effects of a surge in natural gas prices include a spike in coal use and emissions that counter clean energy targets. High fossil fuel prices also are translating into high prices and a supply crunch for key minerals like silicon used in clean energy projects. On a call with investors yesterday, a Tesla Inc. executive said the company is having a hard time finding enough nickel for batteries.

The crisis could pose political problems for the Biden administration, which spent the last few months fending off criticism about rising fuel prices and inflation (Energywire, Oct. 14).

“Energy issues at this moment are as salient to the American public as they have been in quite some time,” said Christopher Borick, who directs the Muhlenberg College Institute of Public Opinion in Pennsylvania, where Biden stopped yesterday to pitch his infrastructure plan.

While gasoline prices have gotten headlines all summer, natural gas prices have risen faster than motor fuels, more than doubling from an average $1.92 per thousand cubic feet in September 2020 to $5.16 last month. By comparison, gasoline prices have risen about 55 percent in the last year, to $3.36 per gallon nationwide this week, according to AAA.

The roots of the problem go back to the beginning of the pandemic and the recession in 2020. Oil and gas prices fell so fast then that many producers, particularly in the U.S., simply stopped drilling.

Oil companies began predicting a few months later that the abrupt shutdown would eventually lead to shortages and price spikes when the economy recovered. Those predictions turned out to be accurate.

With the economy beginning to recover, demand for gas has gone up, but there’s not enough supply to go around.

While the U.S. energy crunch isn’t as severe as Europe’s energy crisis today, and analysts predict that gas prices will gradually fall next year, consumers could be in for a rough couple of months.

Here’s four ways the global energy crisis is impacting the United States, from the electricity sector to the political landscape:

What are the political repercussions?
For the Biden administration, the energy price hikes come amid fears of rising inflation and persistent supply bottlenecks at the nation’s ports as its climate ambitions face headwinds in Congress.

“The confluence of energy prices, logistical challenges and the need to move on climate have raised this to the top tier,” said Borick, who in the past has polled on energy and environmental issues in Pennsylvania.

Borick noted the administration is facing counterpressures: Even as it pushes to decarbonize the nation’s electric system, it wants to keep gas prices in check. High gasoline prices have been linked to declining political approval ratings, including for presidents, even if much of the price hikes are beyond their control.

White House press secretary Jen Psaki said earlier this month that the administration can take steps to address what it called “short-term supply issues,” but also needs to focus on the long term — and climate.

In hopes of capping prices, the White House has spoken with members of OPEC about increasing oil production — though OPEC has little control over natural gas prices. And earlier this month, the administration talked to U.S. oil and gas producers about helping to bring down prices.

That comes even as environmentalists have pushed Biden to ban federal fossil fuel leasing and drilling and stop new projects.

The moves to curb prices have prompted ridicule from Republicans, who have accused Biden of declaring war on U.S. energy by canceling the Keystone XL pipeline.

“The Biden administration won’t say it out loud, yet let’s admit it: There is a crisis,” Sen. John Barrasso (R-Wyo.) said this week on the Senate floor. “It is one that Joe Biden and his administration has created. It is a crisis of Joe Biden’s own making.”

The situation has also resurfaced comparisons to former President Carter, who struggled politically in the 1970s with gasoline shortages and other energy pressures. Some political scientists say, though, the comparison between the two isn’t apples to apples.

"In 1979, the crisis began with the Iranian Revolution, producing a supply shortage. In the USA, some states rationed the supply. That’s not occurring now. Oil prices were also regulated, another difference, “ said Terry Madonna, a senior fellow in residence for political affairs at Millersville University.

A Morning Consult poll released yesterday carried warning signs for Democrats with worries about the economy on the rise across the political spectrum.

Voters, however, were evenly split on how Biden is handling energy. Forty-two percent of respondents approve of Biden’s energy policy, compared with 45 percent who disapproved. The margin of error is 2 percentage points.

Will the electricity mix change?
Higher gas prices are giving coal a boost in some markets.

Atlanta-based Southern Co. told CNBC earlier this week, for instance, that coal was about 17 percent of the company’s power mix last year. That has changed in 2021.

“The unintended consequence of high gas prices is that coal becomes more economic, and so my sense is … our coal production has bumped up above 20 percent,” Southern CEO Tom Fanning said. “Now, how long that’ll persist, I don’t know.”

Fanning said “what we’re seeing right now, and the real challenge in America, is this notion of energy in transition.”

But the U.S. power sector has been evolving for years, with more renewables and less coal on the grid, and experts say the current energy crunch won’t change long-term utility trends in the industry.

“In general, I wouldn’t place too much emphasis on short-term fluctuations,” Jay Apt, a professor at Carnegie Mellon University, said in an email. “There is still a robust supply chain for most components needed for low-pollution power, including renewables.”

In fact, elevated fossil fuel prices, and high natural gas prices in particular, could accelerate the move toward wind, solar and batteries in some areas. That’s because power plants that run on coal and natural gas can be affected by rising and volatile fuel prices, as illustrated by the recent move in commodities globally. That means higher costs to run the facilities, even if power prices often climb along with gas prices.

“If I were a utility planner, this would cause me to double down on new generation from [wind] and solar and storage as opposed to building additional natural gas plants where, you know, I could be having these super high and volatile operating costs,” said Bri-Mathias Hodge, an associate professor in the Department of Electrical, Computer and Energy Engineering at the University of Colorado, Boulder.

Ed Hirs, an energy fellow at the University of Houston, said the current global situation doesn’t change the U.S. power sector’s overall move toward generation with lower operating costs.

For example, he said nuclear and coal plants can require hundreds of employees, and both have fuel costs. Hirs said a gas facility also needs fuel and may need dozens of employees. Wind and solar facilities often need a smaller number of workers and don’t require fuel in their operations, he noted.

“Eventually the cheap wins out,” Hirs said.

That isn’t even factoring in climate change — the reason world leaders are seeking to slash greenhouse gas emissions. Indeed, lowering emissions remains a priority among many states and big companies in the U.S.

Over the next 10 to 15 years, Hirs said, a key question will be whether battery technology can compete economically in terms of backing up renewables. He said a national carbon price, if enacted, would aid renewables and enhance returns on batteries.

“The real battle is going to be between natural gas and battery storage,” Hirs said.

Apt and M. Granger Morgan, who’s also a Carnegie Mellon professor, noted in a Hill piece last month that the U.S. gets about 40 percent of its power from carbon-free sources, including nuclear.

“Modelers and many power system operators agree that it is possible that renewables can cost-effectively make up roughly 80% of electricity generation,” the professors wrote, adding that other sources could include “storage and gas turbines powered with hydrogen, synfuels, or natural gas with carbon capture.”

What about EVs and renewables?
As for electric vehicles, executives with Tesla said on a call yesterday that supply-chain problems are the major brake on production for both vehicles and batteries.

Chief Financial Officer Zachary Kirkhorn said that the company’s factories aren’t running at full capacity because of an ongoing shortage of semiconductor chips. Customers are waiting longer for vehicles, he said, and wait lists are growing.

The challenges extend to raw materials. In batteries, Kirkhorn said, the company is having trouble finding enough nickel, and in vehicles, it is scrounging for aluminum. He said the problem is "not small," and that prices may rise as supply contracts come up for renewal.

The supply problems are creating "cost headwinds," he said, and so are rising labor costs. Tesla is not immune from the worker shortages that are plaguing the entire U.S. economy.

The production woes aren’t limited to Tesla: Automakers around the world have have had their output crimped by the chip shortage that accompanied the economic rebound after pandemic lockdowns. Unlike many other automakers, Tesla hasn’t been forced to pause its factory lines.

Tesla said it is poised to greatly expand its production of batteries for the electric grid — with a caveat.

Last month, Tesla broke ground on a new California factory to make Megapack, its 3 megawatt-per-hour lithium-ion batteries for use by power companies. That future factory’s capacity, 40 gigawatt per hour a year, is vastly more than the 3 GWh it made in the last calendar year.

However, today’s supply-chain problems are braking the making of both Megapack and Powerwall, Tesla’s battery for homes, Kirkhorn said. He added that production will increase "as soon as parts allow us."

Other advocates for EVs and renewable power expressed little concern about the supply crunch’s meaning for their industries, noting that higher prices alone don’t automatically trigger a broader green revolution on their own.

Those problems likely wouldn’t change the immediate course of the energy transition, researchers said.

"Short-term trends, week to week or even month to month, don’t matter much for investors or policy makers," wrote John Graham, a former budget official with the Bush administration and professor at Indiana University’s O’Neill School of Public and Environmental Affairs, in an email to E&E News.

The crunch may give policymakers a glimpse of the future, however, according to one minerals analyst.

"This isn’t going to be an outlier. I think increasingly you’re going to see pockets of the world start to feel these strains," said Andrew Miller, product director at Benchmark Mineral Intelligence, which focuses its research on battery minerals and battery supply chains.

The U.S. and its allies are only now beginning to develop their own supply chains for batteries and other key clean energy technologies, he noted. "The issue you’re facing, and this is one coming over time, is to have the platform in place. You have to have the supply chain of raw materials," he said.

"I think you’re going to see the most turbulence over the coming decade. … It’s not going to be a smooth transition,” added Miller.

How long will gas prices stay high?
The gap between natural gas demand and supply has led to severe price spikes in Europe, where utilities and other gas buyers have to compete against China for cargoes of liquefied natural gas, according to a research note from IHS Markit Ltd.

Here in the U.S., the causes are the same, but the results aren’t as extreme. Less than 10 percent of domestic gas production is exported as LNG, so American customers don’t have to compete as much against overseas buyers.

Instead, gas-hungry sectors of the economy have run into another problem, IHS analyst Matthew Palmer said in an interview. Gas producers have been cautious about increasing their output, largely because of pressure from investors to limit their spending.

“That theme has really put a governor on production,” he said.

The disconnect will likely mean higher home gas bills and higher electric prices this winter, although deep freeze events or warm weather could disrupt the trend, he said. The U.S. Energy Information Administration is predicting that average heating bills for homes that use gas furnaces will rise 30 percent this winter.

This comes as U.S. gas supply remains high, according to a biennial assessment from the Potential Gas Committee, a group of volunteer geoscientists, engineers and other experts.

Including reserves, future gas supply in the U.S. stands at a record 3,863 trillion cubic feet, up 25 tcf from levels reported in 2019, the group said Tuesday at an event co-hosted with the American Gas Association.

Of that total, so-called technically recoverable resources — or those in the ground but not yet recovered — are 3,368 tcf, the PGC said, down less than 0.2 percent from the last assessment.

The amount of technically recoverable gas went relatively unchanged from year-end 2018 for several reasons, including a lack of company activity in exploration efforts last year due to COVID, said Alexei Milkov, the group’s executive director.

Another factor is that basins mature and shale plays “cannot increase in resources forever,” said Milkov, also a professor of geology and geological engineering at the Colorado School of Mines.

Still, Milkov added, “We cannot tell you right now if we are on a new plateau, or if we are going to start seeing more growth in gas resources again, right, because it’s a complex issue.”

The EIA predicts that gas production will increase and prices will begin to drop in 2022.

David Flaherty, CEO of the Republican polling firm Magellan Strategies in Colorado, said prices could particularly hit seniors. But he said he expected the energy crunch to ease in the U.S. well before the election.

“By early summer, this is likely to be behind us,” he said.

Four Facts about Covid and U.S. Electricity Consumption

COVID-19 Impact on U.S. Electricity Consumption shows commercial and industrial demand dropped as residential use rose, with flattened peak loads, weekday-weekend convergence, Texas hourly data, and energy demand as a real-time economic indicator.

 

Key Points

It reduced commercial and industrial demand while raising residential use, shifting peaks and weekday patterns.

✅ Commercial electricity down 12%; industrial down 14% in Q2 2020

✅ Residential use up 10% amid work-from-home and lockdowns

✅ Peaks flattened; weekday-weekend loads converged in Texas

 

This is an important turning point for the United States. We have a long road ahead. But one of the reasons I’m optimistic about Biden-Harris is that we will once again have an administration that believes in science.

To embrace this return to science, I want to write today about a fascinating new working paper by Tufts economist Steve Cicala.

Professor Cicala has been studying the effect of Covid on electricity consumption since back in March, when the Wall Street Journal picked up his work documenting an 18% decrease in electricity consumption in Italy.

The new work, focused on the United States, is particularly compelling because it uses data that allows him to distinguish between residential, commercial, and industrial sectors, against a backdrop of declining U.S. electricity sales over recent years.

Without further ado, here are four facts he uncovers about Covid and U.S. electricity demand during COVID-19 and consumption.

 

Fact #1: Firms Are Using Less
U.S. commercial electricity consumption fell 12% during the second quarter of 2020. U.S. industrial electricity consumption fell 14% over the same period.

This makes sense. The second quarter was by some measures, the worst quarter for the U.S. economy in over 145 years!

Economic activity shrank. Schools closed. Offices closed. Factories closed. Restaurants closed. Malls closed. Even health care offices closed as patients delayed going to the dentist and other routine care. All this means less heating and cooling, less lighting, less refrigeration, less power for computers and other office equipment, less everything.

The decrease in the industrial sector is a little more surprising. My impression had been that the industrial sector had not fallen as far as commercial, but amid broader disruptions in coal and nuclear power that strained parts of the energy economy, the patterns for both sectors are quite similar with the decline peaking in May and then partially rebounding by July. The paper also shows that areas with higher unemployment rates experienced larger declines in both sectors.

 

Fact #2: Households Are Using More
While firms are using less, households are using more. U.S. residential electricity consumption increased 10% during the second quarter of 2020. Consumption surged during March, April, and May, a reflection of the lockdown lifestyle many adopted, and then leveled off in June and July – with much less of the rebound observed on the commercial/industrial side.

This pattern makes sense, too. In Professor Cicala’s words, “people are spending an inordinate amount of time at home”. Many of us switched over to working from home almost immediately, and haven’t looked back. This means more air conditioning, more running the dishwasher, more CNN (especially last week), more Zoom, and so on.

The paper also examines the correlates of the decline. Areas in the U.S. where more people can work from home experienced larger increases. Unemployment rates, however, are almost completely uncorrelated with the increase.

 

Fact #3: Firms are Less Peaky
The paper next turns to a novel dataset from Texas, where Texas grid reliability is under active discussion, that makes it possible to measure hourly electricity consumption by sector.

As the figure above illustrates, the biggest declines in commercial/industrial electricity consumption have occurred Monday through Friday between 9AM and 5PM.

The dashed line shows the pattern during 2019. Notice the large spikes in electricity consumption during business hours. The solid line shows the pattern during 2020. Much smaller spikes during business hours.

 

Fact #4: Everyday is Like Sunday
Finally, we have what I would like to nominate as the “Energy Figure of the Year”.

Again, start with the pattern for 2019, reflected by the dashed line. Prior to Covid, Texas households used a lot more electricity on Saturdays and Sundays.

Then along comes Covid, and turned every day into the weekend. Residential electricity consumption in Texas during business hours Monday-Friday is up 16%(!).

In the pattern for 2020, it isn’t easy to distinguish weekends from weekdays. If you feel like weekdays and weekends are becoming a big blur – you are not alone.

 

Conclusion
Researchers are increasingly thinking about electricity consumption as a real-time indicator of economic activity, even as flat electricity demand complicates utility planning and investment. This is an intriguing idea, but Professor Cicala’s new paper shows that it is important to look sector-by-sector.

While commercial and industrial consumption indeed seem to measure the strength of an economy, residential consumption has been sharply countercylical – increasing exactly when people are not at work and not at school.

These large changes in behavior are specific to the pandemic. Still, with the increased blurring of home and non-home activities we may look back on 2020 as a key turning point in how we think about these three sectors of the economy.

More broadly, Professor Cicala’s paper highlights the value of social science research. We need facts, data, and yes, science, if we are to understand the economy and craft effective policies on energy insecurity and shut-offs as well.

Rooftop Solar Grids

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

 

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

 

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

Hydro once made up around half of Alberta's power capacity. Why does Alberta have so little now?

Alberta Hydropower Potential highlights renewable energy, dams, reservoirs, grid flexibility, contrasting wind and solar growth with limited investment, regulatory hurdles, river basin resources, and decarbonization pathways across Athabasca, Peace, and Slave River systems.

 

Key Points

It is the technical capacity for new hydro in Alberta's river basins to support a more reliable, lower carbon grid.

✅ 42,000 GWh per year developable hydro identified in studies.

✅ Major potential in Athabasca, Peace, and Slave River basins.

✅ Barriers include high capital costs, market design, water rights.

 

When you think about renewable energy sources on the Prairies, your mind may go to the wind farms in southern Alberta, or even the Travers Solar Project, southeast of Calgary.

Most of the conversation around renewable energy in the province is dominated by advancements in solar and wind power, amid Alberta's renewable energy surge that continues to attract attention. 

But what about Canada's main source of electricity — hydro power?

More than half of Canada's electricity is generated from hydro sources, with 632.2 terawatt-hours produced as of 2019. That makes it the fourth largest installed capacity of hydropower in the world. 

But in Alberta, it's a different story. 

Currently, hydro power contributes between three and five per cent of Alberta's energy mix, while fossil fuels make up about 89 per cent.

According to Canada's Energy Future report from the Canada Energy Regulator, by 2050 it will make up two per cent of the province's electricity generation shares.

So why is it that a province so rich in mountains and rivers has so little hydro power?


Hydro's history in Alberta
Hydro power didn't always make up such a small sliver of Alberta's electricity generation. Hydro installations began in the early 20th century as the province's population exploded. 

Grant Berg looks after engineering for hydro for TransAlta, Alberta's largest producer of hydro power with 17 facilities across the province.

"Our first plant was Horseshoe, which started in 1911 that we formed as Calgary Power," he said. 

"It was really in response to the City of Calgary growing and having some power needs."

Berg said in 1913, TransAlta's second installation, the Kananaskis Plant, started as Calgary continued to grow.

Some bigger installations were built in the 1920s, including Ghost reservoir, but by mid-century population growth increased.

"Quite a large build out really, I think in response to the growth in Alberta following the war. So through the 1950s really quite a large build out of hydro from there."

By the 1950s, around half of the province's installed capacity was hydro power.

"Definitely Calgary power was all hydro until the 1950s," said Berg. 


Hydro potential in the province 
Despite the current low numbers in hydroelectricity, Alberta does have potential. 

According to a 2010 study, there is approximately 42,000 gigawatt-hours per year of remaining developable hydroelectric energy potential at identified sites. 

An average home in Alberta uses around 7,200 kilowatt-hours of electricity per year, meaning that the hydro potential could power 5.8 million homes each year. 

"This volume of energy could be sufficient to serve a significant amount of Alberta's load and therefore play a meaningful role in the decarbonization of the province's electric system," the Alberta Electric System Operator said in its 2022 Pathways to Net-Zero Emissions report.

Much of that potential lies in northern Alberta, in the Athabasca, Peace and Slave River basins.

The AESO report says that despite the large resource potential, Alberta's energy-only market framework has attracted limited investment in hydroelectric generation. 

Hydro power was once a big deal in Alberta, but investment in the industry has been in decline since the 1950s. Climate change reporter Christy Climenhaga explains why.
So why does Alberta leave out such a large resource potential on the path to net zero?

The government of Alberta responded to that question in a statement. 

"Hydro facilities, particularly large scale ones involving dams, are associated with high costs and logistical demands," said the Ministry of Affordability and Utilities. 

"Downstream water rights for other uses, such as irrigation, further complicate the development of hydro projects."

The ministry went on to say that wind and solar projects have increased far more rapidly because they can be developed at relatively lower cost and shorter timelines, and with fewer logistical demands.

"Sources from wind power and solar are increasingly more competitive," said Jean-Denis Charlebois, chief economist with the Canadian Energy Regulator. 


Hydro on the path to net zero
Hydro power is incredibly important to Canada's grid, and will remain so, despite growth in wind and solar power across the province.

Charlebois said that across Canada, the energy make-up will depend on the province. 

"Canadian provinces will generate electricity in very different ways from coast to coast. The major drivers are essentially geography," he said. 

Charlebois says that in British Columbia, Manitoba, Quebec and Newfoundland and Labrador, hydropower generation will continue to make up the majority of the grid.

"In Alberta and Saskatchewan, we see a fair bit of potential for wind and solar expansion in the region, which is not necessarily the case on Canada's coastlines," he said.

And although hydro is renewable, it does bring its adverse effects to the environment — land use changes, changes in flow patterns, fish populations and ecosystems, which will have to be continually monitored. 

"You want to be able to manage downstream effects; make sure that you're doing all the proper things for the environment," said Ryan Braden, director of mining and hydro at TransAlta.

Braden said hydro power still has a part to play in Alberta, even with its smaller contributions to the future grid. 

"It's one of those things that, you know, the wind doesn't blow or the sun doesn't shine, this is here. The way we manage it, we can really support that supply and demand," he said.

California Considers Revamping Electricity Rates in Bid to Clean the Grid

California Electricity Rate Overhaul proposes a fixed fee and lower per-kWh rates to boost electrification, renewables, and grid reliability, while CPUC weighs impacts on conservation, low-income customers, and time-of-use pricing across the state.

 

Key Points

A proposal to add fixed fees and cut per-kWh prices to drive electrification, support renewables, and balance grid costs.

✅ Fixed monthly fee plus lower volumetric per-kWh charges

✅ Aims to accelerate EVs, heat pumps, and building electrification

✅ CPUC review weighs equity, conservation, and grid reliability

 

California is contemplating a significant overhaul to its electricity rate structure that could bring major changes to electric bills statewide, a move that has ignited debate among environmentalists and politicians alike. The proposed modifications, spearheaded by the California Energy Commission (CEC), would introduce a fixed fee on electric bills and lower the rate per kilowatt-hour (kWh) used.

 

Motivations for the Change

Proponents of the plan argue that it would incentivize Californians to transition to electric appliances and vehicles, a critical aspect of the state's ambitious climate goals. They reason that a lower per-unit cost would make electricity a more attractive option for applications like home heating and transportation, which are currently dominated by natural gas and gasoline. Additionally, they believe the plan would spur investment in renewable energy sources and distributed generation, ultimately leading to a cleaner electricity grid.

California has some of the most ambitious climate goals in the country, aiming to achieve carbon neutrality by 2045. The transportation sector is the state's largest source of greenhouse gas emissions, and electrification is considered a key strategy for reducing emissions. A 2021 report by the Natural Resources Defense Council (NRDC) found that electrifying all California vehicles and buildings could reduce greenhouse gas emissions by 80% compared to 2020 levels.

 

Concerns and Potential Impacts

Opponents of the proposal, including some consumer rights groups, express apprehensions that it would discourage conservation efforts. They argue that with a lower per-kWh cost, Californians would have less motivation to reduce their electricity consumption. Additionally, they raise concerns that the income-based fixed charges could disproportionately burden low-income households, who may struggle to afford the base charge regardless of their overall electricity consumption.

A recent study by the CEC suggests that the impact on most Californians would be negligible, even as regulators face calls for action over soaring bills from ratepayers across the state. The report predicts that the average household's electricity bill would change by less than $5 per month under the proposed system. However, some critics argue that this study may not fully account for the potential behavioral changes that could result from the new rate structure.

 

Similar Initiatives and National Implications

California is not the only state exploring changes to its electricity rates to promote clean energy. Hawaii and New York have also implemented similar programs to encourage consumers to use electricity during off-peak hours. These time-varying rates, also known as time-of-use rates, can help reduce strain on the electricity grid during peak demand periods.

The California proposal has garnered national attention as other states grapple with similar challenges in balancing clean energy goals with affordability concerns amid soaring electricity prices in California and beyond. The outcome of this debate could have significant implications for the broader effort to decarbonize the U.S. power sector.

 

The Road Ahead

The California Public Utilities Commission (CPUC) is reviewing the proposal and anticipates making a decision later this year, with a potential income-based flat-fee structure under consideration. The CPUC will likely consider the plan's potential benefits and drawbacks, including its impact on greenhouse gas emissions, electricity costs for consumers, and the overall reliability of the grid, even as some lawmakers seek to overturn income-based charges in the legislature.

The decision on California's electricity rates is merely one piece of the puzzle in the fight against climate change. However, it is a significant one, with the potential to shape the state's energy landscape for years to come, including the future of residential rooftop solar markets and investments.

U.S. Renewable and Clean Energy Industries Set Sights on Market Majority

U.S. Majority Renewables by 2030 targets over half of electricity from wind, solar, hydropower, and energy storage, enabling a resilient, efficient grid, deep carbon reductions, fair market rules, and job growth across regions.

 

Key Points

A joint industry pledge for over 50% U.S. power from wind, solar, hydropower, and storage by 2030.

✅ Joint pledge by AWEA, SEIA, NHA, and ESA for a cleaner grid

✅ Focus on resilience, efficiency, affordability, and fair competition

✅ Storage enables flexibility to integrate variable renewables

 

Within a decade, more than half of the electricity generated in the U.S. will come from clean, renewable resources, with analyses indicating that wind and solar could meet 80% of U.S. electricity demand, supported by energy storage, according to a joint commitment today from the American wind, solar, hydropower, and energy storage industries. The American Wind Energy Association (AWEA), Solar Energy Industries Association (SEIA), National Hydropower Association (NHA), and Energy Storage Association (ESA) have agreed to actively collaborate across their industry segments to achieve this target. 

The four industries have released a set of joint advocacy principles that will enable them to realize this bold vision of a majority renewables grid. Along with increased collaboration, these shared principles include building a more resilient, efficient, sustainable, and affordable grid; achieving carbon reductions; and advancing greater competition through electricity market reforms and fair market rules. Each of these areas is critical to attaining the shared vision for 2030.  

The leaders of the four industry associations gathered to announce the shared vision, aligned with a broader 100% renewables pathway pursued nationwide, during the first CLEANPOWER annual conference for businesses across the renewable and clean energy spectrum. 

American Wind Energy Association 

"This collaborative promise sets the stage to deliver on the American electric grid of the future powered by wind, solar, hydropower, and storage," said Tom Kiernan, CEO of the American Wind Energy Association. "Market opportunities for projects that include a mix of technologies have opened up that didn't exist even a few years ago. And demand is growing for integrated renewable energy options. Individually and cooperatively, these sectors will continue growing to meet that demand and create hundreds of thousands of new jobs to strengthen economies from coast to coast, building a better, cleaner tomorrow. In the face of significant challenges the country is currently facing across pandemic response, economic, climate and social injustice problems, we are prepared to help lead toward a healthier and more equitable future."

Solar Energy Industries Association

"These principles are just another step toward realizing our vision for a Solar+ Decade," said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association. "In the face of this dreadful pandemic, our nation must chart a path forward that puts a premium on innovation, jobs recovery and a smarter approach to energy generation, reflecting expected solar and storage growth across the market. The right policies will make a growing American economy fueled by clean energy a reality for all Americans."

National Hydropower Association 

"The path towards an affordable, reliable, carbon-free electricity grid, supported by an ongoing grid overhaul for renewables, starts by harnessing the immense potential of hydropower, wind, solar and storage to work together," said Malcolm Woolf, President and CEO of the National Hydropower Association. "Today, hydropower and pumped storage are force multipliers that provide the grid with the flexibility needed to integrate other renewables onto the grid. By adding new generation onto existing non-powered dams and developing 15 GW of new pumped storage hydropower capacity, we can help accelerate the development of a clean energy electricity grid."

Energy Storage Association 

"We are pleased to join forces with our clean energy friends to substantially reduce carbon emissions by 2030, guided by practical decarbonization strategies, building a more resilient, efficient, sustainable, and affordable grid for generations to come," said ESA CEO Kelly Speakes-Backman. "A majority of generation supplied by renewable energy represents a significant change in the way we operate the grid, and the storage industry is a fundamental asset to provide the flexibility that a more modern, decarbonized grid will require. We look forward to actively collaborating with our colleagues to make this vision a reality by 2030."
