April Sall is a keeper of the Mojave Desert and its mountains, tending a private conservancy in the same canyon where her grandmother homesteaded in the 1920s.

Once considered wasteland, this expanse of sunshine and wind is now a prized battleground between unlikely opponents. For generations, conservationists like Sall's family have guarded the landscape, but 21st-century demands for renewable energy are threatening to crash into the pristine desert, now deemed a gold mine for solar, wind and geothermal farms.

Unlike offshore drilling and other oil and gas ventures in which developers and environmentalists are obvious adversaries, renewable energy is increasingly pitting two kinds of green advocates against each other as the nation seeks alternative sources in the face of record oil prices and global warming, both sides say.

The issue bears upon building a new infrastructure — such as gargantuan transmission towers or wind turbines — to connect remote areas where clean energy is being harvested while conservationists vigilantly protect the land and its life.

The stakes are acute in California, where new state laws demand industry cut carbon emissions to 1990 levels by 2020 and require private utilities to generate 20 percent renewable energy by 2010.

Near Pipes Canyon — where Sall, a preserve manager for the nonprofit Wildlands Conservancy, resides — a group led by the Los Angeles Department of Water and Power is considering building a leg of transmission lines between a substation outside Palm Springs and one in Hesperia, about 80 miles away.

Called Green Path North, the lines would ultimately connect Los Angeles and other communities to the Salton Sea's 2,000 megawatts of geothermal power — enough to juice 2 million homes — as well as solar and wind plants.

The utility group will select from six potential routes, including one as long as 313 miles, but a dispute over a "preferred" route through Pipes Canyon and the broader Morongo Basin has residents fuming.

"There's some conflict due to what's been described as a feeding frenzy for renewable energy in the desert," Sall, 28, said as she walked through a landscape of mesas and the Sawtooth Mountains that surround Pipes Canyon and adjacent Pioneertown.

"If you're going to destroy conservation and pristine lands, then, yeah, how green is it in the end?" Sall asked.

She said she favors cities' building solar plants on warehouse roofs, for example, but the utilities say the desert's geothermal fields provide a steady stream of power and do not rely on weather conditions as solar and wind power do.

Still, the dispute has led to tense meetings, and residents set up a Web site condemning the renewable-energy transmission lines through their communities.

As Congress and presidential candidates John McCain and Barack Obama struggle with the nation's energy crisis, developing alternative energy poses conflicts, too.

"We're really at the forefront of a discussion that is certainly going to be repeated throughout the state of California and nationally as well," said David Nahai, general manager and chief executive officer of the Los Angeles Department of Water and Power.

San Diego Gas & Electric Company (SDG&E), a regulated public utility that provides energy service to 3.7 million people, has awarded Mitsubishi Power an order for a 10 megawatt (MW) / 60 megawatt-hour (MWh) energy storage solution for its Pala-Gomez Creek Energy Storage Project in Pala, California. The battery energy storage system (BESS) will add capacity to help meet high energy demand, support grid reliability and operational flexibility, underscoring the broader benefits of energy storage now recognized by utilities, maximize use of renewable energy, and help prevent outages during peak demand.

The BESS project is Mitsubishi Power’s eighth in California, bringing total capacity to 280 MW / 1,140 MWh of storage to help meet California’s clean energy goals with reliable power to complement renewables, alongside emerging solutions like a California green hydrogen microgrid for added resilience.

Mitsubishi Power’s Emerald storage solution for SDG&E includes full turnkey design, engineering, procurement, and construction, as well as a 10-year long-term service agreement, aligning with CEC long-duration storage funding initiatives underway. It is scheduled to be online in early 2023.

The project will repower an existing energy storage site. It will employ Mitsubishi Power’s Emerald Integrated Plant Controller, which is an Energy Management System (EMS) and Supervisory Control and Data Acquisition (SCADA) system with real-time BESS operation and a monitoring/supervisory control platform. Mitsubishi Power leverages its decades of technology monitoring and diagnostics to turn data into actionable insights to maximize reliability, a priority as regions like Ontario increasingly rely on battery storage to meet rising demand. The Mitsubishi Power Emerald Integrated Plant Controller complies with North American Electric Reliability Corporation critical infrastructure protection (NERC CIP) standards and meets the highest security certification in the energy storage industry (IEC/ISA 62443, NIST 800-53) for maximum protection from cybersecurity risks and vulnerabilities.

For added physical safety, Mitsubishi Power’s solution employs lithium iron phosphate (LFP) battery chemistry, aligning with BESS adoption in New York where safety and performance are critical. Compared with other chemistries, LFP provides longer life and superior thermal stability and chemical stability, while meeting UL 9540 and UL 9540A safety standards.

Fernando Valero, Director, Advanced Clean Technology, SDG&E, said, “SDG&E is committed to achieving net-zero greenhouse gas emissions by 2045. We are increasing our portfolio of energy storage assets, including virtual power plant models, to reach this goal. These assets enhance grid reliability and operational flexibility while maximizing our use of abundant renewable energy sources in California.”

Tom Cornell, Senior Vice President, Energy Storage Solutions, Mitsubishi Power Americas, said, “As more and more renewables come online during the energy transition, BESS solutions are essential to support a reliable and stable grid. We look forward to providing SDG&E with our BESS solution to add capacity, energy, and ancillary services to California’s grid. Mitsubishi Power’s Emerald storage solutions are enabling a smarter and more resilient energy future for our customers in California and around the globe, with projects like an energy storage demonstration in India underscoring this momentum.”

BC Hydro suspends new crypto mining connections due to extreme electricity use

BC Hydro Cryptocurrency Mining Suspension pauses new grid connections for Bitcoin data centers, preserving electricity for EVs, heat pumps, and industry electrification, as Site C capacity and megawatt demand trigger provincial energy policy review.

 

Key Points

An 18-month pause on new crypto-mining grid hookups to preserve electricity for EVs, heat pumps, and electrification.

✅ 18-month moratorium on new BC Hydro crypto connections

✅ Preserves capacity for EVs, heat pumps, and industry

✅ 21 pending mines sought 1,403 MW; Site C adds 1,100 MW

 

New cryptocurrency mining businesses in British Columbia are now temporarily banned from being hooked up to BC Hydro’s electrical grid.

The 18-month suspension on new electricity-connection requests is intended to provide the electrical utility and provincial government with the time needed, a move similar to N.B. Power's pause during a crypto review, to create a permanent framework for any future additional cryptocurrency mining operations.

Currently, BC Hydro already provides electricity to seven cryptocurrency mining operations, and six more are in advanced stages of being connected to the grid, with a combined total power consumption of 273 megawatts. These existing operations, unlike the Siwash Creek project now in limbo, will not be affected by the temporary ban.

The electrical utility’s suspension comes at a time when there are 21 applications to open cryptocurrency mining businesses in BC, even as electricity imports supplement the grid during peaks, which would have a combined total power consumption of 1,403 megawatts — equivalent to the electricity needed for 570,000 homes or 2.3 million battery-electric vehicles annually.

In fact, the 21 cryptocurrency mining businesses would completely wipe out the new electrical capacity gained by building the $16 billion Site C hydroelectric dam, alongside two newly commissioned stations that add supply, which has an output capacity of 1,100 megawatts or enough power for the equivalent of 450,000 homes. Site C is expected to be operational by 2025.

Cryptocurrency mining, such as Bitcoin, use a very substantial amount of electricity to operate high-powered computers around the clock, which perform complex cryptographic and math problems to verify transactions. High electricity needs are the result of not only to run the racks of computers, but to provide extreme cooling given the significant heat produced.

“We are suspending electricity connection requests from cryptocurrency mining operators to preserve our electricity supply for people who are switching to electric vehicles, amid BC Hydro's first call for power in 15 years, and heat pumps, and for businesses and industries that are undertaking electrification projects that reduce carbon emissions and generate jobs and economic opportunities,” said Josie Osborne, the BC minister of energy, mines and low carbon innovation, adding that cryptocurrency mining creates very few jobs for the local economy.

Such businesses are attracted to BC due to the availability of its clean, plentiful, and cheap hydroelectricity, which LNG companies continue to seek for their operations as well.

If left unchecked, the provincial government suggests BC Hydro’s long-term electrical capacity could be wiped out by cryptocurrency mining operations, even as debates over going nuclear persist among residents across the province.

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

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

 

Key Points

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

✅ Peak load shifted to homes; commercial usage declined.

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

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

 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Electricity prices spike in Alberta

Alberta electricity price spike drives 25% CPI surge amid heatwave demand, coal-to-gas conversions, hydro shortfalls, and outages; consumers weigh fixed-rate plans, solar panels, home retrofits, and variable rates to manage bills and grid volatility.

 

Key Points

A recent 25% monthly rise in Alberta power prices driven by heatwave demand, constraints, outages, and fuel shifts.

✅ Heatwave pushed summer peak demand near record

✅ Coal-to-gas conversions and outages tightened supply

✅ Fixed-rate plans, solar, retrofits can reduce bill risk

 

Albertans might notice they are paying more when the next electricity bill comes in as bills on the rise in Calgary alongside provincial trends.

According to the consumer price index, Alberta saw its largest monthly increase since July 2015 as the price of electricity in Alberta rose 25 per cent amid rising electricity prices across the province.

“So I paid negative $70 last month. I actually made money. To supply power to the grid,” said Conrad Nobert, with Climate Action Edmonton.

Norbert is an environmental activist who favours solar power and is warning that prices will continue to go up along with the rising effects from climate change.

“My thoughts are that we can mitigate the price of power going up by taking climate action.”

Alberta experienced one of the hottest summers on record and many people were left scrambling to buy air conditioners.

That demand, along with a number of other factors, drove up prices, prompting some households to lock in rates for protection, says an assistant professor at the University of Calgary who teaches electricity systems.

“At the end of June, during the heatwave, we were a couple megawatts shy of setting an all-time record demand for electricity in the province. That would have been the first time that record for demand in the summer. Traditionally Alberta is a winter peaking province, as shown by an electricity usage record during a deep freeze not long ago,” explained Sara Hastings Simon, an assistant professor at the University of Calgary.

Other reasons for the spike: Alberta’s continuing shift from coal to natural-gas-fired power and changes to electricity production and pricing across the market.

There are a few ways consumers can save money on their power bill; installing solar panels and retrofitting your home to opting for a fixed-rate plan, or considering protections like a consumer price cap where applicable.

“So by default, people are put into a variable rate plan, that changes month to month and that helps to manage prices so you don’t get that big surprise at where prices might be. I think we will get a lot more people looking at that option.”

A statement provided by Dale Nally, Alberta’s Associate Minister of natural gas and electricity, noted recent policy changes including the carbon tax repeal and price cap now in place that affect consumers, says in part:

“This period of high market prices is driven by low supplies of hydro-generated electricity from British Columbia and the pacific northwest, scheduled outages for coal-gas-conversions, unplanned infrastructure outages and unprecedented, and record-breaking high demand due to hot weather. We expect some of the factors that have caused recent increases in prices will be short-term.”

Solar changing shape of electricity prices in Northern Europe

EU Solar Impact on Electricity Prices highlights how rising solar PV penetration drives negative pricing, shifts peak hours, pressures wholesale markets, and challenges grid balancing, interconnection, and flexibility amid changing demand and renewables growth.

 

Key Points

Explains how rising solar PV cuts wholesale prices, shifts negative-price hours, and strains grid flexibility.

✅ Negative pricing events surge with higher solar penetration.

✅ Afternoon price dips replace night-time wind-led lows.

✅ Grid balancing, interconnectors, and flexibility become critical.

 

The latest EU electricity market report has confirmed the affect deeper penetration of solar is having on wholesale electricity prices more broadly.

The Quarterly Report on European Electricity Markets for the final three months of last year noted the number of periods of negative electricity pricing doubled from 2019, to almost 1,600 such events, as global renewables set new records in deployment across markets.

Having experienced just three negative price events in 2019, the Netherlands recorded almost 100 last year “amid a dramatic increase in solar PV capacity,” in the nation, according to the report.

Whilst stressing the exceptional nature of the Covid-19 pandemic on power consumption patterns, the quarterly update also noted a shift in the hours during which negative electric pricing occurred in renewables poster child Germany. Previously such events were most common at night, during periods of high wind speed and low demand, but 2020 saw a switch to afternoon negative pricing. “Thus,” stated the report, “solar PV became the main driver behind prices falling into negative territory in the German market in 2020, as Germany's solar boost accelerated, and also put afternoon prices under pressure generally.”

The report also highlighted two instances of scarce electricity–in mid September and on December 9–as evidence of the problems associated with accommodating a rising proportion of intermittent clean energy capacity into the grid, and called for more joined-up cross-border power networks, amid pushback from Russian oil and gas across the continent.

Rising solar generation–along with higher gas output, year on year–also helped the Netherlands generate a net surplus of electricity last year, after being a net importer “for many years.” The EU report also noted a beneficial effect of rising solar generation capacity on Hungary‘s national electricity account, and cited a solar “boom” in that country and Poland, mirroring rapid solar PV growth in China in recent years.

With Covid-19 falls in demand helping renewables generate more of Europe's electricity (39%) than fossil fuels (36%) for the first time, as renewables surpassed fossil fuels across Europe, the market report observed the 5% of the bloc's power produced from solar closed in on the 6% accounted for by hard coal. In the final three months of the year, European solar output rose 12%, year on year, to 18 TWh and “the increase was almost single-handedly driven by Spain,” the study added.

With coal and lignite-fired power plunging 22% last year across the bloc, it is estimated the European power sector reduced its carbon footprint 14% as part of Europe's green surge although the quarterly report warned cold weather, lower wind speeds and rising gas prices in the opening months of this year are likely to see carbon emissions rebound.

There was good news on the transport front, though, with the report stating the scale of the European “electrically-charged vehicle” fleet doubled in 2020, to 2 million, with almost half a million of the new registrations arriving in the final months of the year. That meant cars with plug sockets accounted for a remarkable 17% of new purchases in Q4, twice the proportion seen in China and a slice of the pie six times bigger than such products claimed in the U.S.

COVID-19 Pandemic Puts $35 Billion in Wind Energy Investments at Risk, Says Industry Group

COVID-19 Impact on U.S. Wind Industry: disrupting wind power projects, tax credits, and construction timelines, risking rural revenues, jobs, and $35B investments; AWEA seeks Congressional flexibility as OEM shutdowns like Siemens Gamesa intensify delays.

 

Key Points

Pandemic disruptions threaten 25 GW of projects, $35B investment, rural revenues, jobs, and tax-credit timelines.

✅ 25 GW at risk; $35B investment jeopardized

✅ Rural taxes and land-lease payments may drop $8B

✅ AWEA seeks Congressional flexibility on tax-credit deadlines

 

In one of the latest examples of the havoc that the novel coronavirus is wreaking on the U.S. economy and the crisis hitting solar and wind sector alike, the American Wind Energy Association (AWEA) -- the national trade association for the U.S. wind industry -- yesterday stated its concerns that COVID-19 will "pose significant challenges to the American wind power industry." According to AWEA's calculations, the disease is jeopardizing the development of approximately 25 gigawatts of wind projects, representing $35 billion in investments, even as wind additions persist in some markets amid the pandemic.

Rural communities, where about 99% of wind projects are located, in particular, face considerable risk. The AWEA estimates that rural communities stand to lose about $8 billion in state and local tax payments and land-lease payments to private landowners. In addition, it's estimated that the pandemic threatens the loss of over 35,000 jobs, and the U.S. wind jobs outlook underscores the stakes, including wind turbine technicians, construction workers, and factory workers.

The development of wind projects is heavily reliant on the earning of tax credits, and debates over a Solar ITC extension highlight potential impacts on wind. However, in order to qualify for the current credits, project developers are bound to begin construction before Dec. 31, 2020. With local and state governments implementing various measures to stop the spread of the virus, the success of project developers' meeting this deadline is dubious, as utility-scale solar construction slows nationwide due to COVID-19. Addressing this and other challenges, the AWEA is turning to the government for help. In the trade association's press release, it states that "to protect the industry and these workers, AWEA is asking Congress for flexibility in allowing existing policies to continue working for the industry through this period of uncertainty."

Illustrating one of the ways in which COVID-19 is affecting the industry, Siemens Gamesa, a global leader in the manufacturing of wind turbines, closed a second Spanish factory this week after learning that a second of its employees had tested positive for the novel coronavirus.
