IEEE announces two smart grid standards

Income Graduated Fixed Charge aligns CPUC billing with utility fixed costs, lowers usage rates, supports electrification, and shifts California investor-owned utilities' electric bills by income, with CARE and Climate Credit offsets for low-income households.

Key Points

A CPUC proposal: an income-based monthly fixed fee with lower usage rates to align costs and aid low-income customers.

✅ Income-tiered fixed fees: $0-$42; CARE: $14-$22, by utility territory

✅ Usage rates drop 16%-22% to support electrification and cost-reflective billing

✅ Lowest-income save ~$10-$20; some higher earners pay ~$10+ more monthly

The Public Advocates Office (PAO) for the California Public Utilities Commission (CPUC) has proposed adding a monthly income-based fixed charge on electric utility bills based on income level.  

The rate change is designed to lower bills for the lowest-income residents while aligning billing more directly with utility costs. 

PAO’s recommendation for the Income Graduated Fixed Charge places fees between $22 and $42 per month in the three major investor-owned utilities’ territories, including an SDG&E minimum charge debate under way, for customers not enrolled in the California Alternative Rates for Energy (CARE) program. As seen below, CARE customers would be charged between $14 per month and $22 a month, depending on income level and territory.

For households earning $50,000 or less per year, the fixed charge would be $0, but only if the California Climate Credit is applied to offset the fixed cost.

Meanwhile, usage-based electricity rates are lowered in the PAO proposal, part of major changes to electric bills statewide. Average rates would be reduced between 16% to 22% for the three major investor-owned utilities.

The lowest-income bracket of Californians is expected to save roughly $10 to $20 a month under the proposal, while middle-income customers may see costs rise by about $20 a month, even as lawmakers seek to overturn income-based charges in Sacramento.

“We anticipate the vast majority of low-income customers ($50,000 or less per year) will have their monthly bills decrease by $10 or more, and a small proportion of the highest income earners ($100,000+ per year) will see their monthly bills rise by $10 or more,” said the PAO.

The charges are an effort to help suppress ever-increasing electricity generation and transmission rates, which are among the highest in the country, with soaring electricity prices reported across California. Rates are expected to rise sharply as wildfire mitigation efforts are implemented by the utilities found at fault for their origin.

“We are very concerned. However, we do not see the increases stopping at this point,” Linda Serizawa, deputy director for energy, PAO, told pv magazine. “We think the pace and scale of the [rate] increases is growing faster than we would have anticipated for several years now.”

Consumer advocates and regulators face calls for action on surging electricity bills across the state.

The proposed changes are also meant to more directly couple billing with the fixed charges that utilities incur, as California considers revamping electricity rates to clean the grid. For example, activities like power line maintenance, energy efficiency programs, and wildfire prevention are not expected to vary with usage, so these activities would be funded through a fixed charge.

Michael Campbell of the PAO’s customer programs team, and leader of the proposed program, likened paying for grid enhancements and other social programs with utility rate increases to “paying for food stamps by taxing food.” Instead, a fixed charge would cover these costs.

PAO said the move to lower rates for usage should help encourage electrification as California moves to replace heating and cooling, appliances, and gas combustion cars with electrified counterparts. In addition, lower rates mean the cost burden of running these devices is improved.

Without reliable, affordable power in heatwaves, health risks rise and cooling, food storage, and daily needs suffer.

✅ Risks: heat illness, dehydration, and indoor temperatures above 90F

✅ Causes: utility shutoffs, aging grid, unpaid bills, remote areas

✅ Relief: cooling centers, aid programs, weatherization, bill credits

In a particular pocket of America, approximately 13,000 families endure the dual challenges of sweltering heat and living without electricity, and the broader risk of summer shut-offs highlights how widespread these pressures have become across the country. This article examines the factors contributing to their plight, the impact of living without electricity during hot weather, and efforts to alleviate these hardships.

Challenges Faced by Families

For these 13,000 families, daily life is significantly impacted by the absence of electricity, especially during the scorching summer months. Without access to cooling systems such as air conditioners or fans, residents are exposed to dangerously high temperatures, which can lead to heat-related illnesses and discomfort, particularly among vulnerable populations such as children, the elderly, and individuals with health conditions, where electricity's role in public health became especially evident.

Causes of Electricity Shortages

The reasons behind the electricity shortages vary. In some cases, it may be due to economic challenges that prevent families from paying utility bills, resulting in disconnections. Other factors include outdated or unreliable electrical infrastructure in underserved communities, as reflected in a recent grid vulnerability report that underscores systemic risks, where maintenance and upgrades are often insufficient to meet growing demand.

Impact of Extreme Heat

During heatwaves, the lack of electricity exacerbates health risks and quality of life issues for affected families, aligning with reports of more frequent outages across the U.S. Furthermore, the absence of refrigeration and cooking facilities can compromise food safety and nutritional intake, further impacting household well-being.

Community Support and Resilience

Despite these challenges, communities and organizations often rally to support families living without electricity. Local nonprofits, community centers, and government agencies provide assistance such as distributing fans, organizing cooling centers, and delivering essentials like bottled water and non-perishable food items during heatwaves to alleviate immediate hardships and improve summer blackout preparedness in vulnerable neighborhoods.

Long-term Solutions

Addressing electricity access issues requires comprehensive, long-term solutions. These may include policy reforms to ensure equitable access to affordable energy, investments in upgrading infrastructure in underserved areas, and expanding financial assistance programs to help families maintain uninterrupted electricity service, in recognition that climate change risks increasingly stress the grid.

European Solar Inverter Demand surges as photovoltaics and residential solar expand during the clean energy transition, driven by high natural gas prices; Germany leads, boosting Enphase and SolarEdge sales for rooftop systems and grid-tied installations.

Key Points

Rising European need for solar inverters, fueled by residential PV growth, high energy costs, and clean energy policies.

✅ Germany leads EU rooftop PV installations

✅ Enphase and SolarEdge see revenue growth

✅ High gas prices and policies spur adoption

Solar equipment makers are expected to post higher quarterly profit, benefiting from strong demand in Europe for critical components that convert energy from the sun into electricity, amid record renewable momentum worldwide.

The continent is emerging as a major market for solar firms as it looks to reduce its dependence on the Russian energy supply and accelerate its clean energy transition, with solar already reshaping power prices in Northern Europe across the region, brightening up businesses of companies such as Enphase Energy (ENPH.O) and SolarEdge Technologies (SEDG.O), which make solar inverters.

Wall Street expects Enphase and SolarEdge to post a combined adjusted net income of $323.8 million for the April-June quarter, a 56.7% jump from a year earlier, even as demand growth slows in the United States.

The energy crisis in Europe is not as acute as last year when Western sanctions on Russia severely crimped supplies, but prices of natural gas and electricity continue to be much higher than in the United States, Raymond James analyst Pavel Molchanov said.

As a result, demand for residential solar keeps growing at a strong pace in the region, with Germany being one of the top markets and solar adoption in Poland also accelerating in recent years across the region.

About 159,000 residential solar systems became operational in the first quarter in Germany amid a solar power boost that reflects policy and demand, a 146% rise from a year earlier, according to BSW solar power association.

Adoption of solar is also helping European homeowners have greater control over their energy costs as fossil fuel prices tend to be more volatile, Morningstar analyst Brett Castelli said.

SolarEdge, which has a bigger exposure to Europe than Enphase, said its first-quarter revenue from the continent more than doubled compared with last year.

In comparison, growth in the United States has been tepid due to lukewarm demand in states like Texas and Arizona where cheaper electricity prices make the economics of residential solar less attractive, even though solar is now cheaper than gas in parts of the U.S. market.

Higher interest rates following the U.S. Federal Reserve's recent actions to tame inflation are also weighing on demand, even as power outage risks rise across the United States.

Analysts also expect weakness in California where a new metering reform reduces the money credited to rooftop solar owners for sending excess power into the grid, underscoring how policy shifts can reshape the sector. The sunshine state accounts for nearly a third of the U.S. residential solar market.

Enphase will report its results on Thursday after the bell, while SolarEdge will release its second-quarter numbers on Aug. 1.

North American Grid Reliability faces extreme weather, climate change, demand spikes, and renewable variability; utilities, AESO, and NERC stress resilience, dispatchable capacity, interconnections, and grid alerts to prevent blackouts during heatwaves and cold snaps.

Key Points

North American grid reliability is the ability to meet demand during extreme weather while maintaining stability.

✅ Extreme heat and cold drive record demand and resource strain.

✅ Balance dispatchable and intermittent generation for resilience.

✅ Expand interconnections, capacity, and demand response to avert outages.

The recent alerts in Alberta's electricity grid during extreme cold have highlighted a broader North American issue, where power systems are more susceptible to being overwhelmed by extreme weather impacts on reliability.

Electricity Canada's chief executive emphasized that no part of the grid is safe from the escalating intensity and frequency of weather extremes linked to climate change across the sector.

“In recent years, during these extreme weather events, we’ve observed record highs in electricity demand,” he stated.

“It’s a nationwide phenomenon. For instance, last summer in Ontario and last winter in Quebec, we experienced unprecedented demand levels. This pattern of extremes is becoming more pronounced across the country.”

The U.S. has also experienced strain on its electricity grids due to extreme weather, with more blackouts than peers documented in studies. Texas faced power outages in 2021 due to winter storms, and California has had to issue several emergency grid alerts during heat waves.

In Canada, Albertans received a government emergency alert two weeks ago, urging an immediate reduction in electricity use to prevent potential rotating blackouts as temperatures neared -40°C. No blackouts occurred, with a notable decrease in electricity use following the alert, according to the Alberta Electric System Operator (AESO).

AESO's data indicates an increase in grid alerts in Alberta for both heatwaves and cold spells, reflecting dangerous vulnerabilities noted nationwide. The period between 2017 and 2020 saw only four alerts, in contrast to 17 since 2021.

Alberta's electricity grid reliability has sparked political debate, including proposals for a western Canadian grid to improve reliability, particularly with the transition from coal-fired plants to increased reliance on intermittent wind and solar power. Despite this debate, the AESO noted that the crisis eased when wind and solar generation resumed, despite challenges with two idled gas plants.

Bradley pointed out that Alberta's grid issues are not isolated. Every Canadian region is experiencing growing electricity demand, partly due to the surge in electric vehicles and clean energy technologies. No province has a complete solution yet.

“Ontario has had to request reduced consumption during heatwaves,” he noted. “Similar concerns about energy mix are present in British Columbia or Manitoba, especially now with drought affecting their hydro-dependent systems.”

The North American Electric Reliability Corporation (NERC) released a report in November warning of elevated risks across North America this winter for insufficient energy supplies, particularly under extreme conditions like prolonged cold snaps.

While the U.S. is generally more susceptible to winter grid disruptions, and summer blackout warnings remain a concern, the report also highlights risks in parts of Canada. Saskatchewan faces a “high” risk due to increased demand, power plant retirements, and maintenance, whereas Quebec and the Maritimes are at “elevated risk.”

Mark Olson, NERC’s manager of reliability assessments, mentioned that Alberta wasn't initially considered at risk, illustrating the challenges in predicting electricity demand amid intensifying extreme weather.

Rob Thornton, president and CEO of the International District Energy Association, acknowledged public concerns about grid alerts but reassured that the risk of a catastrophic grid failure remains very low.

“The North American grid is exceptionally reliable. It’s a remarkably efficient system,” he said.

However, Thornton emphasized the importance of policies for a resilient and reliable electricity system through 2050 and beyond. This involves balancing dispatchable and intermittent electricity sources, investing in extra capacity, enhancing macrogrids and inter-jurisdictional connections, and more.

“These grid alerts raise awareness, if not anxiety, about our energy future,” Thornton concluded.

Ontario IESO COVID-19 Control Room Measures detail how essential operators safeguard the electricity grid with split shifts, backup control centres, real-time balancing, deep cleaning, social distancing, and shelter-in-place readiness to maintain reliable power.

Key Points

Measures that protect essential grid operators with split shifts, backup sites, and hygiene to keep power reliable.

✅ Split teams across primary and backup control centres

✅ 12-hour shifts with remote handoffs and deep cleaning

✅ Real-time grid modeling to balance demand and supply

A group of personnel key to keeping Ontario's electricity system functioning may end up locked down in their control centres due to the COVID-19 crisis, according to the head of the province's power operator.

But that has so far proven unnecessary with a change-up in routine, Independent Electricity System Operator CEO Peter Gregg said.

While about 90 per cent of staff were sent to work from home on March 13, another 48 control-room operators deemed essential are still going into work, Gregg said in an interview.

"We identified a smaller cohort of critical operations room staff that need to go in to operate the system out of our control centres," Gregg said. "My biggest concern is to maintain their health, their safety as we rely on them to do this critical work."

Some of the operators manage power demand and supply in real time as Ontario electricity demand shifts, by calling for more or less generation and keeping an eye on the distribution grid, which also allows power to flow to and from Ontario's neighbours. Others do scenario planning and modelling to prepare for changes.

The essential operators have been split into eight teams of six each working 12-hour shifts. The day crew works out of a control centre near Toronto and the night shift out of a backup centre in the city's west end, Gregg said.

"That means that we're not having physical hand-off between control room operators on shift change -- we can do it remotely -- and it also allows us to do deep cleansing," Gregg said. "We're fortunate that the way the room is set up allows us to practice good social distancing."

Should it become necessary, he said, bed, food and other on-site arrangements have been made to allow the operators to stay at their workplaces as a similar agency in New York has done.

"If we do need to shelter these critical employees in place, we've got the ability to do so."

IESO is responsible for ensuring a balance between supply and demand for electricity across the province. Because power cannot be stored, the IESO ensures generators produce enough power to meet peak demand while making sure they don't produce too much.

"You're seeing, obviously, commercial demand drop, some industrial demand drop," Gregg said. "But you're also seeing a shift in the demand curve as well, where normally you have people heading off to work and so residential demand would go down. But obviously with them staying home, you're seeing an increase in residential electricity use across the province."

Some utilities have indicated no cuts to peak rates for self-isolating customers, with Hydro One peak pricing remaining in place for now.

IESO also runs and settles the wholesale electricity markets. Market prices are set based on accepted offers to supply electricity, while programs supporting stable electricity pricing for industrial and commercial users can affect costs against forecast demand.

With the pandemic forcing many businesses to close and people to stay home, and provincial electricity relief for families and small businesses in place, typical power needs fallen about seven per cent at a time of year that would normally see demand soften anyway. It remains to be seen whether, and how much, power needs shift further amid stringent isolation measures and the ongoing economic impact of the outbreak.

Gregg said the operator is constantly modeling different possibilities.

"What we do normally is prepare for all of these sort of emergency scenarios, as reflected in the U.S. grid response coverage, and test and drill for these," he said. "What we're experiencing over the last few weeks is that those drills come in handy because they help us prepare for when the real-time situation actually happens."

Surkhan-Pul-e-Khumri Power Line links Uzbekistan and Afghanistan via a 260-kilometer transmission line, boosting electricity exports, grid reliability, and regional trade; ADB-backed financing could open Pakistan's energy market with 24 million kWh daily.

Key Points

A 260-km line to expand Uzbekistan power exports to Afghanistan, ADB-funded, with possible future links to Pakistan.

✅ 260 km Surkhan-Pul-e-Khumri transmission link

✅ +70% electricity exports; up to 24M kWh daily

✅ ADB $70M co-financing; $32M from Uzbekistan

Senior officials with Uzbekistan’s state-run power company have said work has begun on building power cables to Afghanistan that will enable them to increase exports by 70 per cent, echoing regional trends like Ukraine resuming electricity exports after grid repairs.

Uzbekenergo chief executive Ulugbek Mustafayev said in a press conference on March 24 that construction of the Afghan section of the 260-kilometer Surkhan-Pul-e-Khumri line will start in June.

The Asian Development Bank has pledged $70 million toward the final expected $150 million bill of the project. Another $32 million will come from Uzbekistan.

Mustafayev said the transmission line would give Uzbekistan the option of exporting up to 24 million kilowatt hours to Afghanistan daily, similar to Ukraine's electricity export resumption amid shifting regional demand.

“We could potentially even reach Pakistan’s energy market,” he said, noting broader regional ambitions like Iran's bid to be a power hub linking regional grids.

This project was given fresh impetus by Afghan President Ashraf Ghani’s visit to Tashkent in December, mirroring cross-border energy cooperation such as Iran-Iraq energy talks in the region. His Uzbek counterpart, Shavkat Mirziyoyev, had announced at the time that work was set to begin imminently on the line, which will run from the village of Surkhan in Uzbekistan’s Surkhandarya region to Pul-e-Khumri, a town in Afghanistan just south of Kunduz.

In January, Mirziyoyev issued a decree ordering that the rate for electricity deliveries to Afghanistan be dropped from $0.076 to $0.05 per kilowatt.

Mustafayev said up to 6 billion kilowatt hours of electricity could eventually be sent through the power lines. More than 60 billion kilowatt hours of electricity was produced in Uzbekistan in 2017.

According to Tulabai Kurbonov, an Uzbek journalist specializing in energy issues, the power line will enable the electrification of the the Hairatan-Mazar-i-Sharif railroad joining the two countries. Trains currently run on diesel. Switching over to electricity will help reduce the cost of transporting cargo.

There is some unhappiness, however, over the fact that Uzbekistan plans to sell power to Afghanistan when it suffers from significant shortages domestically and wider Central Asia electricity shortages persist.

"In the villages of the Ferghana Valley, especially in winter, people are suffering from a shortage of electricity,” said Munavvar Ibragimova, a reporter based in the Ferghana Valley. “You should not be selling electricity abroad before you can provide for your own population. What we clearly see here is the favoring of the state’s interests over those of the people.”
