Delmarva Power unveiled a plan for a proposed interstate electric transmission line.

The mid-Atlantic Power Pathway, utility representatives told the state Public Service Commission, is the first interstate transmission line in the region to come along in 25 years.

The last new line connected New York to Washington, D.C.

The proposed $1.2 billion, 230-mile line is designed to ease power congestion on the Delmarva Peninsula, in the Washington-Baltimore area and in southern New Jersey. Power Pathway lines would create what Bill Gausman, vice president of asset management for Delmarva's parent company Pepco Holdings, called a continuous loop through the Maryland, Delaware, New Jersey and Pennsylvania region.

For the first time, the Delmarva Peninsula would be connected to electric sources from the south and west. "It would significantly enhance the reliability of the electric system on the Delmarva Peninsula," Delmarva spokesman Bill Yingling said. Mr. Gausman and Delmarva Power regional president Gary Stockbridge said it's time to expand the transmission grid for more reliable electric supply.

"Although we're excited about this, we recognize it's one piece of the puzzle," Mr. Stockbridge told the PSC and representatives from various state agencies. "We believe it is important to get additional power to the Delmarva Peninsula, since a PJM report indicates that the peninsula will experience a 2.5 percent annual growth in electricity demand over the next decade," Delmarva spokesman Matt Likovich said.

The transmission line would have a Dover connection. Power Pathway lines would serve utilities up and down the peninsula, Mr. Yingling said, and therefore could travel along the existing Delmarva Power rights of way in Delaware.

Since Delmarva has power lines that run through the Dover area, Mr. Yingling said, the vast majority of the new lines would run through these existing rights of way. The transmission line would increase power import capability onto the peninsula by more than 1,000 megawatts, or 1 million homes. Some of the power sources placed on the grid would be from coal-fired and nuclear power plants.

PSC executive director Bruce H. Burcat said Delaware already receives some of its electricity from nuclear sources, such as New Jersey-based plants. Because Delmarva Power still has to acquire various permits in multiple states, the utility isn't sure when it will be able to start construction on the project, although it hopes to begin next year and finish by 2014.

"They still have a long way to go," Mr. Burcat said. "They have to get a lot of things done by 2014."

Delmarva has a proposed memorandum of understanding between Eastern Shore Natural Gas Corp. and Maryland Broadband Cooperative to identify and select a utility corridor crossing the Chesapeake Bay, minimize environmental impacts from construction and perform joint environmental studies.

It must establish agreements with environmental and engineering consulting firms, review existing easement agreements and determine where additions are needed and new agreements are required. It has letters of support from Gov. Ruth Ann Minner, the Delmarva Peninsula Planning Association, Delaware Municipal Electric Corp. and Delaware Electric Cooperative.

Mr. Gausman said the cost of the project would be shared throughout the region. The Delmarva Peninsula customer share would be less than 10 percent, he said.

Mr. Stockbridge said members of PJM Interconnection, one of the world's largest power grids, approved the project in October.

Rising Electricity Prices: Inflation, Climate Change, and Clean Energy Challenges

Rising Electricity Prices are driven by inflation, climate change, and the clean energy transition, affecting energy bills, grid resilience, and supply. Renewables, storage, and infrastructure upgrades shape costs, volatility, and long-term sustainability.

 

Key Points

Rising electricity prices stem from inflation, climate risk, and costs of integrating clean energy and storage into modern grids.

✅ Inflation raises fuel, materials, and labor costs for utilities

✅ Extreme weather damages infrastructure and strains peak demand

✅ Clean energy rollout needs storage, backup, and grid upgrades

 

In recent months, consumers have been grappling with a concerning trend: rising electricity prices across the country. This increase is not merely a fluctuation but a complex issue shaped by a confluence of factors including inflation, climate change, and the transition to clean energy. Understanding these dynamics is crucial for navigating the current energy landscape and preparing for its future.

Inflation and Its Impact on Energy Costs

Inflation, the economic phenomenon of rising prices across various sectors, has significantly impacted the cost of living, including electricity and natural gas prices for households. As the price of goods and services increases, so too does the cost of producing and delivering electricity. Energy production relies heavily on raw materials, such as metals and fuels, whose prices have surged in recent years. For instance, the costs associated with mining, transporting, and refining these materials have risen, thereby increasing the operational expenses for power plants.

Moreover, inflation affects labor costs, as wages often need to keep pace with the rising cost of living. As utility companies face higher expenses for both materials and labor, these costs are inevitably passed on to consumers in the form of higher electricity bills.

Climate Change and Energy Supply Disruptions

Climate change also plays a significant role in driving up electricity prices. Extreme weather events, such as hurricanes, heatwaves, and floods, have become more frequent and severe due to climate change. These events disrupt energy production and distribution by damaging infrastructure, impeding transportation, and affecting the availability of resources.

For example, hurricanes can knock out power plants and damage transmission lines, leading to shortages and higher costs. During periods of extreme summer heat across many regions, heatwaves can strain the power grid as increased demand for air conditioning pushes the system to its limits. Such disruptions not only lead to higher immediate costs but also necessitate costly repairs and infrastructure upgrades.

Additionally, the increasing frequency of natural disasters forces utilities to invest in more resilient infrastructure, as many utilities spend more on delivery to harden grids and reduce outages, which adds to overall costs. These investments, while necessary for long-term reliability, contribute to short-term price increases for consumers.

The Transition to Clean Energy

The shift towards clean energy is another pivotal factor influencing electricity prices. While renewable energy sources like wind, solar, and hydro power are crucial for reducing greenhouse gas emissions and combating climate change, their integration into the existing grid presents challenges.

Renewable energy infrastructure requires substantial initial investment. The construction of wind farms, solar panels, and the associated grid improvements involve significant capital expenditure. These upfront costs are often reflected in electricity prices. Moreover, renewable energy sources can be intermittent, meaning they do not always produce electricity at times of high demand. This intermittency necessitates the development of energy storage solutions and backup systems, which further adds to the costs.

Utilities are also transitioning from fossil fuel-based energy production to cleaner alternatives, a process that involves both technological and operational shifts and intersects with the broader energy crisis impacts on electricity, gas, and EVs nationwide. These changes can temporarily increase costs as utilities phase out old systems and implement new ones. While the long-term benefits of cleaner energy include environmental sustainability and potentially lower operating costs, the transition period can be financially burdensome for consumers.

The Path Forward

Addressing rising electricity prices requires a multifaceted approach. Policymakers must balance the need for immediate relief, as California regulators face calls for action amid soaring bills, with the long-term goals of sustainability and resilience. Investments in energy efficiency can help reduce overall demand and ease pressure on the grid. Expanding and modernizing energy infrastructure to accommodate renewable sources can also mitigate price volatility.

Additionally, efforts to mitigate climate change through improved resilience and adaptive measures can reduce the frequency and impact of extreme weather events, thereby stabilizing energy costs.

Consumer education is vital in this process. Understanding the factors driving electricity prices can empower individuals to make informed decisions about energy consumption and conservation. Furthermore, exploring energy-efficient appliances and practices can help manage costs in the face of rising prices.

In summary, the rising cost of electricity is a multifaceted issue influenced by inflation, climate change, and the transition to clean energy, and recent developments show Germany's rising energy costs in the coming year. While these factors pose significant challenges, they also offer opportunities for innovation and improvement in how we produce, distribute, and consume energy. By addressing these issues with a balanced approach, it is possible to navigate the complexities of rising electricity prices while working towards a more sustainable and resilient energy future.

California Skirts Blackouts With Heat Wave to Test Grid Again

California Heatwave Power Crisis strains CAISO as record demand triggers emergency alerts, demand response, and rolling blackout warnings. PG&E prepares outages while solar fades at peak, drought cuts hydropower, and reliability hinges on conservation.

 

Key Points

Extreme heat driving record demand in California, straining CAISO and prompting conservation to avert rolling blackouts.

✅ CAISO hit a record 52 GW peak load amid triple-digit heat

✅ Emergency alerts spurred demand response, cutting load spikes

✅ Solar drop and drought-weakened hydro worsened evening shortfall

 

California narrowly avoided blackouts for a second successive day even as blistering temperatures pushed electricity demand to a record and stretched the state’s power grid close to its limits.

The state imposed its highest level of energy emergency for several hours late Tuesday and urged consumers to turn off lights, curb air conditioners and shut off power-hungry appliances after a day of extraordinary stress on electricity infrastructure as temperatures in many regions topped 110 degrees Fahrenheit (43 Celsius).

Electricity use had reached 52 gigawatts Tuesday, easily breaking a record that stood since 2006, according to the California Independent System Operator. The state issued emergency alerts direct to cell phones in several counties asking for immediate power conservation, and grid data show that demand plunged in response. Emergency measures were finally lifted at about 9 p.m. local time.

Much of California remains under an excessive heat warning through Friday, with authorities already preparing for more severe pressure on the power system on Wednesday amid a looming supply shortage across the grid. “We aren’t out of the woods yet,” Governor Gavin Newsom said in a message posted on his office’s Twitter account. “We will see continued extreme temps this week and if we rallied today, we can do it again.”

The state’s largest power company, PG&E Corp. said earlier Tuesday that it had notified about 525,000 homes and businesses that they could lose power for up to two hours. That warning came as temperatures in downtown Sacramento hit 116 degrees Fahrenheit, topping a previous 1925 record.

Newsom earlier signed an executive order extending until Friday emergency measures to free up additional power supplies, rather than allowing them to expire as planned on Wednesday. Many state buildings were ordered to power down lights and air conditioning at 4 p.m., and he urged residents and businesses to conserve the equivalent of 3 gigawatts of power in order to stave off blackouts. 

California's Early Brush With Blackouts Bodes Ill For Days Ahead

California faced a similar energy emergency Monday, which was alleviated in part by activating temporary gas-fired power plants operated by the California Department of Water Resources. The current heat wave, which began in the last week of August, is remarkable in both its ferocity and duration, according to officials. 

The prospect of outages underscores how grids have become vulnerable in the face of extreme weather as California transitions from fossil fuels to renewable energy, an approach it is increasingly exporting to Western states as well. California's climate policies have aggressively closed natural-gas power plants in recent years, leaving the state increasingly dependent on solar farms that go dark late in the day just as electricity demand peaks. At the same time, the state is enduring the Southwest’s worst drought in 1,200 years, sapping hydropower production.

The average 15-minute wholesale power price in Caiso surged to $1,806 a megawatt-hour at 4:45 p.m. local time, according to the grid operator’s website.

Average day-ahead prices top $300 a megawatt-hour in Southern California
  
A break from the heat will come across Southern California later this week, thanks to Tropical Storm Kay in the Pacific Ocean, according to weather officials. Kay is forecast to edge up the coastline of Mexico’s Baja California peninsula. As it moves north, the storm will pump moisture and clouds into Southern California and Arizona, taking an edge off the heat.

Trump Tariff Threat Delays Quebec's Green Energy Bill

Quebec Energy Bill Tariff Delay disrupts Canada-U.S. trade, renewable energy investment, hydroelectric expansion, and clean technology projects, as Trump tariffs on aluminum and steel raise costs, threatening climate targets and green infrastructure timelines.

 

Key Points

A policy pause in Quebec from U.S. tariff threats, disrupting clean investment, hydro expansion, and climate targets.

✅ Tariff risk inflates aluminum and steel project costs.

✅ Quebec delays clean energy legislation amid trade uncertainty.

✅ Hydroelectric reliance complicates emissions reduction timelines.

 

The Trump administration's tariff threat has had a significant impact on Quebec's energy sector, with tariff threats boosting support for projects even as the uncertainty resulted in the delay of a critical energy bill. Originally introduced to streamline energy development and tackle climate change, the bill was meant to help transition Quebec towards greener alternatives while fostering economic growth. However, the U.S. threat to impose tariffs on Canadian goods, including energy products, introduced a wave of uncertainty that led to a pause in the bill's legislative process.

Quebec’s energy bill had ambitious goals of transitioning to renewable sources like wind, solar, and hydroelectric power. It sought to support investments in clean technologies and the expansion of the province's clean energy infrastructure, as the U.S. demand for Canadian green power continues to grow across the border. Moreover, it emphasized the reduction of carbon emissions, an important step towards meeting Quebec's climate targets. At its core, the bill aimed to position the province as a leader in green energy development in Canada and globally.

The interruption caused by President Donald Trump's tariff rhetoric has, however, cast a shadow over the legislation. Tariffs, if enacted, would disproportionately affect Canada's energy exports, with electricity exports at risk under growing tensions, particularly in sectors like aluminum and steel, which are integral to energy infrastructure development. These tariffs could increase the cost of energy-related projects, thereby hindering Quebec's ability to achieve its renewable energy goals and reduce carbon emissions in a timely manner.

The tariff threat was seen as a part of the broader trade tensions between the U.S. and Canada, a continuation of the trade war that had escalated under Trump’s presidency. In this context, the Quebec government was forced to reconsider its legislative priorities, with policymakers citing concerns over the potential long-term consequences on the energy industry, as leaders elsewhere threatened to cut U.S.-bound electricity to exert leverage. With the uncertainty around tariffs and trade relations, the government opted to delay the bill until the geopolitical situation stabilized.

This delay underscores the vulnerability of Quebec’s energy agenda to external pressures. While the provincial government had set its sights on an ambitious green energy future, it now faces significant challenges in ensuring that its projects remain economically viable under the cloud of potential tariffs, even as experts warn against curbing Quebec's exports during the dispute. The delay in the energy bill also reflects broader challenges faced by the Canadian energy sector, which is highly integrated with the U.S. market.

The situation is further complicated by the province's reliance on hydroelectric power, a cornerstone of its energy strategy that supplies markets like New York, where tariffs could spike New York energy prices if cross-border flows are disrupted. While hydroelectric power is a clean and renewable source of energy, there are concerns about the environmental impact of large-scale dams, and these concerns have been growing in recent years. The tariff threat may prompt a reevaluation of Quebec’s energy mix and force the government to balance its environmental goals with economic realities.

The potential imposition of tariffs also raises questions about the future of North American energy cooperation. Historically, Canada and the U.S. have enjoyed a symbiotic energy relationship, with significant energy trade flowing across the border. The energy bill in Quebec was designed with the understanding that cross-border energy trade would continue to thrive. The Trump administration's tariff threat, however, casts doubt on this stability, forcing Quebec lawmakers to reconsider how they proceed with energy policy in a more uncertain trade environment.

Looking forward, Quebec's energy sector will likely need to adjust its strategies to account for the possibility of tariffs, while still pushing for a sustainable energy future, especially if Biden outlook for Canada's energy proves more favorable for the sector in the medium term. It may also open the door for deeper discussions about diversification, both in terms of energy sources and trade partnerships, as Quebec seeks to mitigate the impact of external threats. The delay in the energy bill, though unfortunate, may serve as a wake-up call for Canadian lawmakers to rethink how they balance environmental goals with global trade realities.

Ultimately, the Trump tariff threat highlights the delicate balance between regional energy ambitions and international trade dynamics. For Quebec, the delay in the energy bill could prove to be a pivotal moment in shaping the future of its energy policy.

To Limit Climate Change, Scientists Try To Improve Solar And Wind Power

Wisconsin Solar and Wind Energy advances as rooftop solar, utility-scale farms, and NREL perovskite solar cells improve efficiency; wind turbines gain via wake modeling, yaw control, and grid-scale battery storage to cut carbon emissions.

 

Key Points

It is Wisconsin's growth in rooftop and utility-scale solar plus optimized wind turbines to cut carbon emissions.

✅ Perovskite solar cells promise higher efficiency, need longevity

✅ Wake modeling and yaw control optimize wind farm output

✅ Batteries and bids can offset reliance on natural gas

 

Solar energy in Wisconsin continued to grow in 2019, as more homeowners had rooftop panels installed and big utilities started building multi-panel solar farms.

Wind power is increasing more slowly in the state. However, renewable power developers are again coming forward with proposals for multiple turbines.

Nationally, researchers are working on ways to get even more energy from solar and wind, with the U.S. moving toward 30% electricity from wind and solar in coming years, as states like Wisconsin aim to reduce their carbon emissions over the next few decades.

One reason solar energy is growing in Wisconsin is due to the silicon panels becoming more efficient. But scientists haven't finished trying to improve panel efficiency. The National Renewable Energy Laboratory (NREL) in Golden, Col., is one of the research facilities experimenting with brushing a lab-made solution called perovskite onto a portion of a panel called a solar cell.

In a demonstration video supplied by NREL, senior scientist Maikel van Hest said that, in the lab anyway, the painted cell and its electrical connections called contacts, produce more energy:

"There you go! That's how you paint a perovskite solar cell. And you imagine that ultimately what you could do is you could see a company come in with a truck in front of your house and they would basically paint on the contacts first, dry those, and paint the perovskite over it. That you would have photovoltaic cells on the side of your house, put protective coating on it, and we're done."

Another NREL scientist, David Moore, says the new solar cells could be made faster and help meet what's expected to be a growing global demand for energy. However, Moore says the problem has been lack of stability.

"A solar cell with perovskites will last a couple years. We need to get that to 20-25 years, and that's the big forefront in perovskite research, is getting them to last longer," Moore told members of the Society of Environmental Journalists during a recent tour of NREL.

Another part of improving renewable energy is making wind turbines more productive. At NREL's Insight Center, a large screen showing energy model simulations dominates an otherwise darkened room. Visualization scientist Nicholas Brunhart-Lupo points to a display on the screen that shows how spinning turbines at one edge of a wind farm can cause an airflow called a wake, which curtails the power generation of other turbines.

"So what we find in these simulations is these four turbines back here, since they have this used air, this low-velocity wake being blown to their faces, they're only generating about 20% of the energy they should be generating," he explains.

Brunhart-Lupo says the simulations can help wind farm developers with placement of turbines as well as adjustments to the rotor and blades called the yaw system.

Continued progress with renewables may be vital to any state or national pledges to reduce use of fossil fuels and carbon emissions linked to climate change, including Biden's solar expansion plan as a potential pathway. Some scientists say to limit a rise in global temperature, there must be a big decline in emissions by 2050.

But even utilities that say they support use of more renewables, as why the grid isn't 100% renewable yet makes clear, aren't ready to let go of some energy sources. Jonathan Adelman of Xcel Energy, which serves part of Western Wisconsin, says Xcel is on track to close its last two coal-fired power plants in Minnesota. But he says the company will need more natural gas plants, even though they wouldn't run as often.

"It's not perfect. And it is in conflict with our ultimate goal of being carbon-free," says Adelman. "But if we want to facilitate the transition, we still need resources to help that happen."

Some in the solar industry would like utilities that say they need more natural gas plants to put out competitive bids to see what else might be possible. Solar advocates also note that in some states, energy regulators still favor the utilities.

Meanwhile, solar slowly marches ahead, including here in southeastern Wisconsin, as Germany's solar power boost underscores global momentum.

On the roof of a ranch-style home in River Hills, a work crew from the major solar firm Sunrun recently installed mounting brackets for solar panels.

Sunrun Public Policy Director Amy Heart says she supports research into more efficient renewables. But she says another innovation may have to come in the way regulators think.

"Instead of allowing and thinking about from the perspective of the utility builds the power plant, they replace one plant with another one, they invest in the infrastructure; is really thinking about how can these distributed solutions like rooftop solar, peer-to-peer energy sharing, and especially rooftop solar paired with batteries how can that actually reduce some of what the utility needs?

Large-scale energy storage batteries are already being used in some limited cases. But energy researchers continue to make improvements to them, too, with cheap solar batteries beginning to make widespread adoption more feasible as scientists race to reduce the expected additional harm of climate change.
