Ireland announces package of measures to secure electricity supplies

Hourly Electricity Emissions Tracking maps grid balancing areas, embodied emissions, and imports/exports, revealing carbon intensity shifts across PJM, ERCOT, and California ISO, and clarifying renewable energy versus coal impacts on health and climate.

Key Points

An hourly method tracing generation, flows, and embodied emissions to quantify carbon intensity across US balancing areas.

✅ Hourly traces of imports/exports and generation mix

✅ Consumption-based carbon intensity by balancing area

✅ Policy insights for renewables, coal, health costs

In the United States, electricity generation accounts for nearly 30% of our carbon emissions. Some states have responded to that by setting aggressive renewable energy standards; others are hoping to see coal propped up even as its economics get worse. Complicating matters further is the fact that many regional grids are integrated, and as America goes electric the stakes grow, meaning power generated in one location may be exported and used in a different state entirely.

Tracking these electricity exports is critical for understanding how to lower our national carbon emissions. In addition, power from a dirty source like coal has health and environment impacts where it's produced, and the costs of these aren't always paid by the parties using the electricity. Unfortunately, getting reliable figures on how electricity is produced and where it's used is challenging, even for consumers trying to find where their electricity comes from in the first place, leaving some of the best estimates with a time resolution of only a month.

Now, three Stanford researchers—Jacques A. de Chalendar, John Taggart, and Sally M. Benson—have greatly improved on that standard, and they have managed to track power generation and use on an hourly basis. The researchers found that, of the 66 grid balancing areas within the United States, only three have carbon emissions equivalent to our national average, and they have found that imports and exports of electricity have both seasonal and daily changes. de Chalendar et al. discovered that the net results can be substantial, with imported electricity increasing California's emissions/power by 20%.

Hour by hour
To figure out the US energy trading landscape, the researchers obtained 2016 data for grid features called balancing areas. The continental US has 66 of these, providing much better spatial resolution on the data than the larger grid subdivisions. This doesn't cover everything—several balancing areas in Canada and Mexico are tied in to the US grid—and some of these balancing areas are much larger than others. The PJM grid, serving Pennsylvania, New Jersey, and Maryland, for example, is more than twice as large as Texas' ERCOT, in a state that produces and consumes the most electricity in the US.

Despite these limitations, it's possible to get hourly figures on how much electricity was generated, what was used to produce it, and whether it was used locally or exported to another balancing area. Information on the generating sources allowed the researchers to attach an emissions figure to each unit of electricity produced. Coal, for example, produces double the emissions of natural gas, which in turn produces more than an order of magnitude more carbon dioxide than the manufacturing of solar, wind, or hydro facilities. These figures were turned into what the authors call "embodied emissions" that can be traced to where they're eventually used.

Similar figures were also generated for sulfur dioxide and nitrogen oxides. Released by the burning of fossil fuels, these can both influence the global climate and produce local health problems.

Huge variation
The results were striking. "The consumption-based carbon intensity of electricity varies by almost an order of magnitude across the different regions in the US electricity system," the authors conclude. The low is the Bonneville Power grid region, which is largely supplied by hydropower; it has typical emissions below 100kg of carbon dioxide per megawatt-hour. The highest emissions come in the Ohio Valley Electric region, where emissions clear 900kg/MW-hr. Only three regional grids match the overall grid emissions intensity, although that includes the very large PJM (where capacity auction payouts recently fell), ERCOT, and Southern Co balancing areas.

Most of the low-emissions power that's exported comes from the Pacific Northwest's abundant hydropower, while the Rocky Mountains area exports electricity with the highest associated emissions. That leads to some striking asymmetries. Local generation in the hydro-rich Idaho Power Company has embodied emissions of only 71kg/MW-hr, while its imports, coming primarily from Rocky Mountain states, have a carbon content of 625kg/MW-hr.

The reliance on hydropower also makes the asymmetry seasonal. Local generation is highest in the spring as snow melts, but imports become a larger source outside this time of year. As solar and wind can also have pronounced seasonal shifts, similar changes will likely be seen as these become larger contributors to many of these regional grids. Similar things occur daily, as both demand and solar production (and, to a lesser extent, wind) have distinct daily profiles.

The Golden State
California's CISO provides another instructive case. Imports represent less than 30% of its total electric use in 2016, yet California electricity imports provided 40% of its embodied emissions. Some of these, however, come internally from California, provided by the Los Angeles Department of Water and Power. The state itself, however, has only had limited tracking of imported emissions, lumping many of its sources as "other," and has been exporting its energy policies to Western states in ways that shape regional markets.

Overall, the 2016 inventory provides a narrow picture of the US grid, as plenty of trends are rapidly changing our country's emissions profile, including the rise of renewables and the widespread adoption of efficiency measures and other utility trends in 2017 that continue to evolve. The method developed here can, however, allow for annual updates, providing us with a much better picture of trends. That could be quite valuable to track things like how the rapid rise in solar power is altering the daily production of clean power.

More significantly, it provides a basis for more informed policymaking. States that wish to promote low-emissions power can use the information here to either alter the source of their imports or to encourage the sites where they're produced to adopt more renewable power. And those states that are exporting electricity produced primarily through fossil fuels could ensure that the locations where the power is used pay a price that includes the health costs of its production.

Ontario Electricity Capacity Gap threatens reliability as IESO forecasts shortfalls from the Pickering shutdown and rapid electrification, requiring new low-emission nuclear generation to meet net-zero targets, maintain baseload, and stabilize the grid.

Key Points

Expected 2030 shortfalls from Pickering closure and electrification, requiring new low-emission nuclear to meet net-zero.

✅ IESO projects a 3.6-9.5 GW capacity gap by 2030

✅ Pickering shutdown removes baseload, stressing reliability

✅ New low-emission nuclear needed to meet net-zero targets

Ontario faces an electricity supply shortage and reliability risks in the next four to eight years and will not meet net-zero objectives without building new low-emission, nuclear generation starting as soon as possible, according to a report released yesterday by the Power Workers' Union (PWU). The capacity needed to fill the expected supply gap will be equivalent to doubling the province's planned nuclear fleet in eight years.

The planned closure of the Pickering nuclear power plant in 2025 and the increase in demand from electrification of the economy are the drivers behind a capacity gap in 2030 of at least 3.6 GW which could widen to as much as 9.5 GW, Electrification Pathways for Ontario to Reduce Emissions, finds. Ontario's Independent Electricity System Operator (IESO) has since 2013 been forecasting a significant gap in the province's electricity supply due the closure of Pickering, but has been underestimating the impact of electrification, the report says.

In addition, the electrification of buildings, transport and industry sectors that will be needed to achieve goals of net-zero emissions by 2050 that being set by the federal government and civil society will see the province's electricity demand increase by at least 130% over current planning forecasts, and potentially by over 190%. Leveraging electricity, natural gas and hydrogen synergies can reduce supply needs, but 55 GW of new electricity capacity, including new large-scale nuclear plants, will still be needed by 2050 - four times Ontario's current nuclear and hydro assets - the report finds.

These findings underscore the urgent need for a paradigm shift in Ontario's electricity planning and procurement process, the authors say, adding that immediate action is needed both to mitigate the system reliability risks and enable the significant societal benefits needed to pursue net-zero objectives. Planning for procurement to replace Pickering's capacity, or to pursue life extension options, must begin as soon as possible.

"Policymakers around the world realise climate change can't be tackled without nuclear. Ontario's nuclear fleet has delivered emissions reductions for over 50 years," PWU President Jeff Parnell said. "In fact, without building new nuclear units, Ontario will miss its emission reduction targets and carbon emissions from electricity generation will rise dramatically, as explored in why Ontario's power could get dirtier today."

"This report clearly shows that Ontario cannot sustain the low-carbon status of its hydro and nuclear-based electricity system, decarbonise its economy and meet its carbon reduction targets without new nuclear or continued operation at Pickering in the near term. Most disturbing is the fact that we are already well behind and needed to start planning for this capacity yesterday," he said.

The six operating Candu reactors at Ontario Power Generation's Pickering plant have been kept in operation to provide baseload electricity during the refurbishment of units at the Darlington and Bruce plants. Currently, the company plans to shut down Pickering units 1 and 4 in 2024 and units 5 to 8 in 2025, even as Ontario moves to refurbish Pickering B to extend life.

Middle Tennessee Power Outages disrupt 100,000+ customers as severe thunderstorms, straight-line winds, downed trees, and debris challenge Nashville crews, slow restoration amid COVID-19, and threaten more hail, flash flooding, and damaging gusts.

Key Points

Blackouts across Nashville after severe storms and winds, leaving customers without power and facing restoration delays.

✅ Straight-line winds 60-80 mph toppled trees and power lines

✅ 130,000+ customers impacted; some outages may last 1-2 weeks

✅ Restoration slowed by debris, COVID-19 protocols, and new storms

Some middle Tennessee residents could be without electricity for up to two weeks after strong thunderstorms swept through the area Sunday, knocking out power for more than 100,000 customers, a scale comparable to Los Angeles outages after a station fire.

"Straight line winds as high as 60-80 miles per hour knocked down trees, power lines and power polls, interrupting power to 130,000 of our 400,000+ customers," Nashville Electric said in a statement Monday. The utility said the outage was one of the largest on record, though Carolina power outages recently left a quarter-million without power as well.

"Restoration times will depend on individual circumstances. In some cases, power could be out for a week or two" as challenges related to coronavirus and the need for utilities adapt to climate change complicated crews' responses and more storms were expected, the statement said. "This is unfortunate timing on the heels of a tornado and as we deal with battling COVID-19."

Metropolitan Nashville and Davidson County Mayor John Cooper also noted that the power outages were especially inconvenient, a challenge similar to Hong Kong families without power during Typhoon Mangkhut, as people were largely staying home to slow the spread of coronavirus. He also pointed out that the storms came on the two month anniversary of the Nashville tornado that left at least two dozen people dead.

"Crews are working diligently to restore power and clear any debris in neighborhoods," Cooper said.

He said that no fatalities were reported in the county but sent condolences to Spring Hill, whose police department reported that firefighter Mitchell Earwood died during the storm due to "a tragic weather-related incident" while at his home and off duty. He had served with the fire department for 10 years.

The Metro Nashville Department of Public Works said it received reports of more than 80 downed trees in Davidson County.

Officials also warn that copper theft can be deadly when electrical infrastructure is damaged after storms.

The National Weather Service Nashville said a 72 mph wind gust was measured at Nashville International Airport — the fifth fastest on record.

The weather service warned that strong storms with winds of up to 75 mph, large hail, record-long lightning bolt potential seen in the U.S., and isolated flash flooding could hit middle Tennessee again Monday afternoon and night.

"Treat Severe Thunderstorm Warnings the same way you would Tornado Warnings and review storm safety tips before you JUST TAKE SHELTER," the NWS instructs. "70 mph is 70 mph whether it's spinning around in a circle or blowing in a straight line."

Russia-Ukraine Energy Ceasefire Violations escalate as U.S.-brokered truce frays, with drone strikes, shelling, and grid attacks disrupting gas supply and power infrastructure across Kursk, Luhansk, Sumy, and Dnipropetrovsk, prompting sanctions calls.

Key Points

Alleged breaches of a U.S.-brokered truce, with both sides striking power grids, gas lines, and critical energy nodes.

✅ Drone and artillery attacks reported on power and gas assets

✅ Both sides accuse each other of breaking truce terms

✅ U.S. mediation faces verification and compliance hurdles

Russia and Ukraine have traded fresh accusations regarding violations of a fragile energy ceasefire, brokered by the United States, which both sides had agreed to last month. These new allegations highlight the ongoing tensions between the two nations and the challenges involved in implementing a truce amid global energy instability in such a complex and volatile conflict.

The U.S.-brokered ceasefire had initially aimed to reduce the intensity of the fighting, specifically in the energy sector, where both sides had previously targeted each other’s infrastructure. Despite this agreement, the accusations on Wednesday suggest that both Russia and Ukraine have continued their attacks on each other's energy facilities, a crucial aspect of the ceasefire’s terms.

Russia’s Ministry of Defence claimed that Ukrainian forces had launched drone and shelling attacks in the western Kursk region, cutting power to over 1,500 homes. This attack allegedly targeted key infrastructure, leaving several localities without electricity. Additionally, in the Russian-controlled part of Ukraine's Luhansk region, a Ukrainian drone strike hit a gas distribution station, severely disrupting the gas supply for over 11,000 customers in the area around Svatove.

In response, Ukrainian President Volodymyr Zelensky accused Russia of breaking the ceasefire. He claimed that Russian drone strikes had targeted an energy substation in Ukraine’s Sumy region, while artillery fire had damaged a power line in the Dnipropetrovsk region, leaving nearly 4,000 consumers without power even as Ukraine increasingly leans on electricity imports to stabilize the grid. Ukraine's accusations painted a picture of continued Russian aggression against critical energy infrastructure, a strategy that had previously been a hallmark of Russia’s broader military operations in the war.

The U.S. had brokered the energy truce as a potential stepping stone toward a more comprehensive ceasefire agreement. However, the repeated violations raise questions about the truce’s viability and the broader prospects for peace between Russia and Ukraine. Both sides are accusing each other of undermining the agreement, which had already been delicate due to previous suspicions and mistrust. In particular, the U.S. administration, led by President Donald Trump, has expressed impatience with the slow progress in moving toward a lasting peace, amid debates over U.S. national energy security priorities.

Kremlin spokesperson Dmitry Peskov defended Russia’s stance, emphasizing that President Vladimir Putin had shown a commitment to peace by agreeing to the energy truce, despite what he termed as daily Ukrainian attacks on Russian infrastructure. He reiterated that Russia would continue to cooperate with the U.S., even though the Ukrainian strikes were ongoing. This perspective suggests that Russia remains committed to the truce but views Ukraine’s actions as violations that could potentially derail efforts to reach a more comprehensive ceasefire.

On the other hand, President Zelensky argued that Russia was not adhering to the terms of the ceasefire. He urged the U.S. to take a stronger stance against Russia, including increasing sanctions on Moscow as punishment for its violations. Zelensky’s call for heightened sanctions is a continuation of his efforts to pressure international actors, particularly the U.S. and European countries, to provide greater energy security support for Ukraine’s struggle and to hold Russia accountable for its actions.

The ceasefire’s fragility is also reflected in the differing views between Ukraine and Russia on what constitutes a successful resolution. Ukraine had proposed a full 30-day ceasefire, but President Putin declined, raising concerns about monitoring and verifying compliance with the terms. This disagreement suggests that both sides are not entirely aligned on what a peaceful resolution should look like and how it can be realistically achieved.

The situation is complicated by the broader context of the war, which has now dragged on for over three years. The conflict has seen significant casualties, immense destruction, and deep geopolitical ramifications. Both countries are heavily reliant on their energy infrastructures, making any attack on these systems not only a military tactic but also a form of economic warfare. Energy resources, including electricity and natural gas, have become central to the ongoing conflict, with both sides using them to exert pressure on the other amid Europe's deepening energy crisis that reverberates beyond the battlefield.

As of now, it remains unclear whether the recent violations of the energy ceasefire will lead to a breakdown of the truce or whether the United States will intervene further to restore compliance, even as Ukraine prepares for winter amid energy challenges. The situation remains fluid, and the international community continues to closely monitor the developments. The U.S., which played a central role in brokering the energy ceasefire, has made it clear that it expects both sides to uphold the terms of the agreement and work toward a more permanent cessation of hostilities.

The continued accusations between Russia and Ukraine regarding the breach of the energy ceasefire underscore the challenges of negotiating peace in such a complex and entrenched conflict. While both sides claim to be upholding their commitments, the reality on the ground suggests that reaching a full and lasting peace will require much more than temporary truces. The international community, particularly the U.S., will likely continue to push for stronger actions to enforce compliance and to prevent the conflict from further escalating. The outcome of this dispute will have significant implications for both countries and the broader European energy landscape and security landscape.

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.
