The Northern Indiana Public Service Co. will permanently shut down its power plant in Gary, invest about $600 million in pollution controls and pay $13 million in environmental mitigation and penalties as a result of a settlement with the federal government.

The legal agreement will create jobs and result in reductions in air pollution, specifically of a pollutant that can lead to asthma attacks and cause premature death, one that can aggravate respiratory and heart disease and smells like rotten eggs, and one that contributes to ozone and acid rain.

Here's approximately how much air pollution will be reduced from NIPSCO's power plants in Northwest Indiana as a result of the settlement. The numbers are compared to 2008 emission levels:

• Sulfur dioxide smells like rotten eggs and contributes to acid rain, smog and haze: 46,000 tons per year

• Nitrogen oxides contribute to ozone: 18,000 tons per year

• Particulate matter contributes to asthma attacks: 4,500 tons per year.

When all the settlement requirements are complete in 2018, NIPSCO's nitrogen oxide emissions will be 35 percent below current rates and sulfur dioxide emissions will be 80 percent below current rates, according to NIPSCO.

"The pollution reductions achieved in this settlement will ensure that the people of Indiana and neighboring states have cleaner, healthier air to breathe," said Cynthia Giles, assistant administrator for the U.S. Environmental Protection Agency's Office of Enforcement and Compliance Assurance. "EPA is committed to advancing its national enforcement initiative to reduce air pollution from the largest sources of emissions."

At the peak of investment into environmental controls, NIPSCO said as many as 1,000 jobs could be created for local contractors and within the company over the next eight years.

"The installations are staged in. We're hoping on the skilled craft, we can bring it and hold it for five to eight years. So it's not that you bring in 1,000 people for six months and then done," said Kelly Carmichael, director of environmental health and safety for NiSource. "This is an extended period of time, which always helps with the labor force because then people can relocate."

The agreement comes after the EPA accused NIPSCO in 2004 of installing equipment at its coal-fired power plants in Chesterton Bailly Station, Michigan City and Wheatfield R.N. Schahfer in the 1980s and 1990s without first obtaining the required permits. The equipment was supposed to be the best available to remove pollutants, but was not, EPA said.

The Bailly station at the time was located in an area that had not attained EPA's air quality standard for ozone or sulfur dioxide — both of which NIPSCO was contributing to by overpolluting. Both are supposed to be reduced as part of the settlement.

The agreement covers all NIPSCO's plants. As part of the agreement, NIPSCO will install pollution control requirements at the three operating plants and permanently close the Gary plant Dean H. Mitchell on North Clark Road, which has been out of operation since an economic downturn in 2002.

"It's our plan to decommission it. In terms of future plans for that site, it's not been decided. We're looking at a wide array of options," said NIPSCO spokesman Nick Meyer. "The airport is looking to expand.... It could include building a new generating facility on top of that site. Nothing's been finalized."

NIPSCO said it would not initiate another rate case to cover the $600 million, but gradually apply small amounts to customer bills as the investments are made, as allowed by the Indiana Utility Regulatory Commission. One new unit, for instance, could be paid for over an 18-year period.

"In terms of actual impact on customer bills, that only occurs after we spend the money to do it. It's not like we come in and say we need $600 million today. As we spend it, we're going to go to the commission for coverage," Meyer said. "We are running calculations on when these investments would likely be made and how that will impact bills over time. We're talking small percentage points each year over the next eight years and beyond. I'm hesitant to say 4 percent, 2 percent, 1 percent. All we can say is, these will be gradual over time."

NIPSCO has invested more than $350 million in environmental controls since 1990 and reduced certain emissions by 70 percent. That investment is almost entirely paid off. With the additional upgrades, NIPSCO's plants will be ready to meet even stricter air pollution standards expected from EPA in the coming years.

As part of the settlement, NIPSCO has to spend $1.5 million to $2 million to acquire and restore environmentally sensitive lands adjacent to the Indiana Dunes National Lakeshore and donate it to the park. The company would like a partner to match its money. A stakeholder work group would be established to lay out a plan by the first quarter of 2012.

NIPSCO will also invest $9.5 million in various environmental improvement projects, including replacing diesel engines in its fleet with hybrid or electric cars, and sponsoring a rebate program to replace wood-burning stoves and outdoor boilers.

When an area has not attained standards, companies face much tougher requirements to start or relocate there. State Rep. Mara Candelaria Reardon, D-Munster, said the settlement will benefit the environment while creating new opportunities for economic development.

"The new investments will create hundreds of needed jobs in northern Indiana as we try to emerge from the state's deep economic recession," she said in a statement. "The significant reductions in emissions also will improve the air quality for families who live in neighborhoods near the NIPSCO electric generating stations."

The agreement between NIPSCO, EPA, the Department of Justice and the Indiana Department of Environmental Management is subject to a 30-day public comment period and court approval. It's the 21st settlement under a federal effort to enforce against power plants that allegedly violated the Clean Air Act.

Russian Strikes on Western Ukraine Cause Power Outages

Ukraine Energy Grid Attacks intensify as missile strikes and drone raids hit power plants, substations, and transmission lines, causing blackouts, disrupted logistics, and humanitarian strain during winter, despite repairs, air defense, and allied aid.

 

Key Points

Missile and drone strikes on Ukraine's power grid to force blackouts, strain civilians, and disrupt military logistics.

✅ Targets: power plants, substations, transmission lines

✅ Impacts: blackouts, heating loss, hospital strain

✅ Goals: erode morale, disrupt logistics, force aid burdens

 

Russia’s continued strikes on Ukraine have taken a severe toll on the country’s critical infrastructure, particularly its energy grid, as Ukraine continues to keep the lights on despite sustained bombardment. In recent months, Western Ukraine has increasingly become a target of missile and drone attacks, leading to widespread power outages and compounding the challenges faced by the civilian population. These strikes aim to cripple Ukraine's resilience during a harsh winter season and disrupt its wartime operations.

Targeting Energy Infrastructure

Russian missile and drone assaults on Ukraine’s energy grid are part of a broader strategy to weaken the country’s morale and capacity to sustain the war effort. The attacks have primarily focused on power plants, transmission lines, and substations. Western Ukraine, previously considered a relative safe haven due to its distance from front-line combat zones, is now experiencing the brunt of this campaign.

The consequences of these strikes are severe. Rolling blackouts and unplanned outages have disrupted daily life for millions of Ukrainians, though authorities say there are electricity reserves that could stabilize supply if no new strikes occur, leaving homes without heating during freezing temperatures, hospitals operating on emergency power, and businesses struggling to maintain operations. The infrastructure damage has also affected water supplies and public transportation, further straining civilian life.

Aimed at Civilian and Military Impact

Russia’s targeting of Ukraine’s power grid has dual purposes. On one hand, it aims to undermine civilian morale by creating hardships during the cold winter months, even as Ukraine works to keep the lights on this winter through contingency measures. On the other, it seeks to hinder Ukraine’s military logistics and operations, which heavily rely on a stable energy supply for transportation, communications, and manufacturing of military equipment.

These attacks coincide with a broader strategy of attritional warfare, where Moscow hopes to exhaust Ukraine’s resources and diminish its ability to continue its counteroffensive operations. By disrupting critical infrastructure, Russia increases pressure on Ukraine's allies to step up humanitarian and military aid, stretching their capacities.

Humanitarian Consequences

The impact of these power cuts on the civilian population is profound. Millions of Ukrainians are enduring freezing temperatures without consistent access to electricity or heating. Vulnerable populations, such as the elderly, children, and those with disabilities, face heightened risks of hypothermia and other health issues.

Hospitals and healthcare facilities are under immense strain, relying on backup generators that cannot sustain prolonged use. In rural areas, where infrastructure is already weaker, the effects are even more pronounced, leaving many communities isolated and unable to access essential services.

Humanitarian organizations have ramped up efforts to provide aid, including distributing generators, warm clothing, and food supplies, while many households pursue new energy solutions to weather blackouts. However, the scale of the crisis often outpaces the resources available, leaving many Ukrainians to rely on their resilience and community networks.

Ukraine's Response

Despite the challenges, Ukraine has demonstrated remarkable resilience in the face of these attacks. The government and utility companies are working around the clock to repair damaged infrastructure and restore power to affected areas. Mobile repair teams and international assistance have played crucial roles in mitigating the impact of these strikes.

Ukraine’s Western allies have also stepped in to provide support. The European Union, the United States, and other countries have supplied Ukraine with energy equipment, financial aid, and technical expertise to help rebuild its energy grid, though recent decisions like the U.S. ending support for grid restoration complicate planning and procurement. Additionally, advanced air defense systems provided by Western nations have helped intercept some of the incoming missiles and drones, though not all attacks can be thwarted.

Russia’s Escalation Strategy

Russia’s focus on Western Ukraine reflects a shift in its strategy. Previously, attacks were concentrated on front-line areas and major urban centers in the east and south. However, by targeting the western regions, Moscow seeks to disrupt the relatively stable zones where displaced Ukrainians and critical supply chains are located.

Western Ukraine is also a hub for receiving and distributing international aid and military supplies. Striking this region not only undermines Ukraine’s internal stability but also sends a message to its allies about Russia’s willingness to escalate the conflict further.

Broader Implications

The attacks on Ukraine’s energy grid have broader geopolitical implications. By targeting infrastructure, Russia intensifies the pressure on Ukraine’s allies to continue providing support, even as Kyiv has at times helped Spain amid blackouts when capacity allowed, testing their unity and resolve. The destruction also poses long-term challenges for Ukraine’s post-war recovery, as rebuilding a modern and resilient energy system will require significant investments and time.

Moreover, these attacks highlight the vulnerability of civilian infrastructure in modern warfare, echoing that electricity is civilization amid winter conditions. The deliberate targeting of non-combatant assets underscores the need for international efforts to strengthen the protection of critical infrastructure and address the humanitarian consequences of such tactics.

The Russian attacks on Western Ukraine's power grid are a stark reminder of the devastating human and economic costs of the ongoing conflict. While Ukraine continues to demonstrate resilience and adaptability, the scale of destruction underscores the need for sustained international support. As the war drags on, the focus must remain on mitigating civilian suffering, rebuilding critical infrastructure, and pursuing a resolution that ends the violence and stabilizes the region.

First Nuclear Reactors Built in 30 Years Take Shape at Georgia Power Plant

Vogtle Units 3 and 4 are Westinghouse AP1000 nuclear reactors under construction in Waynesboro, Georgia, led by Southern Nuclear, Georgia Power, and Bechtel, adding 2,234 MWe of carbon-free baseload power with DOE loan guarantees.

 

Key Points

Vogtle Units 3 and 4 are AP1000 reactors in Georgia delivering 2,234 MWe of low-carbon baseload electricity.

✅ Each unit: Westinghouse AP1000, 1,117 MWe capacity.

✅ Managed by Southern Nuclear, built by Bechtel.

✅ DOE loan guarantees support financing and risk.

 

Construction is ongoing for two new nuclear reactors, Units 3 and 4, at Georgia Power's Alvin W. Vogtle Electric Generating Plant in Waynesboro, Ga. the first new nuclear reactors to be constructed in the United Stated in 30 years, mirroring a new U.S. reactor startup that will provide electricity to more than 500,000 homes and businesses once operational.

Construction on Unit 3 started in March 2013 with an expected completion date of November 2021. For Unit 4, work began in November 2013 with a targeted delivery date of November 2022. Each unit houses a Westinghouse AP1000 (Advanced Passive) nuclear reactor that can generate about 1,117 megawatts (MWe). The reactor pressure vessels and steam generators are from Doosan, a South Korean firm.

The pouring of concrete was delayed to 2013 due to the United States Nuclear Regulatory Commission issuing a license amendment which permitted the use of higher-strength concrete for the foundations of the reactors, eliminating the need to make additional modifications to reinforcing steel bar.

The work is occurring in the middle of an operational nuclear facility, and the construction area contains many cranes and storage areas for the prefabricated parts being installed. Space also is needed for various trucks making deliveries, especially concrete.

The reactor buildings, circular in shape, are several hundred feet apart from one another and each one has an annex building and a turbine island structure. The estimated total price for the project is expected in the $18.7 billion range. Bechtel Corporation, which built Units 1 and 2, was brought in January 2017 to take over the construction that is being overseen by Southern Nuclear Operating Company (SNOC), which operates the plant.

The project will require the equivalent of 3,375 miles of sidewalk; the towers for Units 3 and 4 are 60 stories high and have two million pound CA modules; the office space for both units is 300,000 sq. ft.; and there are more than 8,000 construction workers over 30 percent being military veterans. The new reactors will create 800 permanent jobs.

Southern Nuclear and Georgia Power took over management of the construction project in 2017 after Westinghouse's Chapter 11 bankruptcy. The plant, built in the late 1980s with Unit 1 becoming operational in 1987 and Unit 2 in 1989, is jointly owned by Georgia Power (45.7 percent), Oglethorpe Power Corporation (30 percent), Municipal Electric Authority of Georgia (22.7 percent) and Dalton Utilities (1.6 percent).

"Significant progress has been made on the construction of Vogtle 3 and 4 since the transition to Southern Nuclear following the Westinghouse bankruptcy," said Paul Bowers, Chairman, President and CEO of Georgia Power. "While there will always be challenges in building the first new nuclear units in this country in more than 30 years, we remain focused on reducing project risk and maintaining the current project momentum in order to provide our customers with a new carbon-free energy source that will put downward pressure on rates for 60 to 80 years."

The Vogtle and Hatch nuclear plants currently provide more than 20 percent of Georgia's annual electricity needs. Vogtle will be the only four-unit nuclear facility in the country. The energy is needed to meet the rising demand for electricity as the state expects to have more than four million new residents by 2030.

The plant's expansion is the largest ongoing construction project in Georgia and one of the largest in the state's history, while comparable refurbishments such as the Bruce reactor overhaul progress in Canada. Last March an agreement was signed to secure approximately $1.67 billion in additional Department of Energy loan guarantees. Georgia Power previously secured loan guarantees of $3.46 billion.

The signing highlighted the placement of the top of the containment vessel for Unit 3, echoing the Hinkley Point C roof lift seen in the U.K., which signified that all modules and large components had been placed inside it. The containment vessel is a high-integrity steel structure that houses critical plant components. The top head is 130 ft. in diameter, 37 ft. tall, and weighs nearly 1.5 million lbs. It is comprised of 58 large plates, welded together with each more than 1.5 in. thick.

"From the very beginning, public and private partners have stood with us," said Southern Company Chairman, President and CEO Tom Fanning. "Everyone involved in the project remains focused on sustaining our momentum."

Bechtel has completed more than 80 percent of the project, and the major milestones for 2019 have been met, aligning with global nuclear milestones reported across the industry, including setting the Unit 4 pressurizer inside the containment vessel last February, which will provide pressure control inside the reactor coolant system. More specialized construction workers, including craft labor, have been hired via the addition of approximately 300 pipefitters and 350 electricians since November 2018. Another 500 to 1,000 craft workers have been more recently brought in.

A key accomplishment occurred last December when 1,300 cu. yds. of concrete were poured inside the Unit 4 containment vessel during a 21-hour operation that involved more than 100 workers and more than 120 truckloads of concrete. In 2018 alone, more than 23,000 cu. yds. of concrete were poured part of the nearly 600,000 cu. yds. placed since construction started, and the installation of more than 16,200 yds. of piping.

Progress also has been solid for Unit 3. Last January the integrated head package (IHP) was set inside the containment vessel. The IHP, weighing 475,000 lbs. and standing 48 ft. tall, combines several separate components in one assembly and allows the rapid removal of the reactor vessel head during a refueling outage. One month earlier, the placement of the third and final ring for containment vessel, and the placement of the fourth and final reactor coolant pump (RCP, 375,000 lbs.), were executed.

"Weighing just under 2 million pounds, approximately 38 feet high and with a diameter of 130 feet, the ring is the fourth of five sections that make up the containment vessel," stated a Georgia Power press release. "The RCPs are mounted to the steam generator and serve a critical part of the reactor coolant system, circulating water from the steam generator to the reactor vessel, allowing sufficient heat transfer for safe plant operation. In the same month, the Unit 3 shield building with additional double-decker panels, was placed.

According to a construction update from Georgia Power, a total of eight six-panel sections have been placed, with each one measuring 20 ft. tall and 114 ft. wide, weighing up to 300,000 lbs. To date, more than half of the shield building panels have been placed for Unit 3. The shield building panels, fabricated in Newport News, Va., provide structural support to the containment cooling water supply and protect the containment vessel, which houses the reactor vessel.

Building the reactors is challenging due to the design, reflecting lessons from advanced reactors now being deployed. Unit 3 will have 157 fuel assemblies, with each being a little over 14 ft. long. They are crucial to fuelling the reactor, and once the initial fueling is completed, nearly one-third of the fuel assemblies will be replaced for each re-fuelling operation. In addition to the Unit 3 containment top, placement crews installed three low-pressure turbine rotors and the generator rotor inside the unit's turbine building.

Last November, major systems testing got underway at Unit 3 as the site continues to transition from construction toward system operations. The Open Vessel Testing will demonstrate how water flows from the key safety systems into the reactor vessel ensuring the paths are not blocked or constricted.

"This is a significant step on our path towards operations," said Glen Chick, Vogtle 3 & 4 construction executive vice president. "[This] will prepare the unit for cold hydro testing and hot functional testing next year both critical tests required ahead of initial fuel load."

It also confirms that the pumps, motors, valves, pipes and other components function as designed, a reminder of how issues like the South Carolina plant leak can disrupt operations when systems falter.

"It follows the Integrated Flush process, which began in August, to push water through system piping and mechanical components that feed into the Unit 3 reactor vessel and reactor coolant loops for the first time," stated a press release. "Significant progress continues ... including the placement of the final reinforced concrete portion of the Unit 4 shield building. The 148-cubic yard placement took eight hours to complete and, once cured, allows for the placement of the first course of double-decker panels. Also, the upper inner casing for the Unit 3 high-pressure turbine has been placed, signifying the completion of the centerline alignment, which will mean minimal vibration and less stress on the rotors during operations, resulting in more efficient power generation."

The turbine rotors, each weighing approximately 200 tons and rotating at 1,800 revolutions per-minute, pass steam through the turbine blades to power the generator.

The placement of the middle containment vessel ring for Unit 4 was completed in early July. This required several cranes to work in tandem as the 51-ft. tall ring weighed 2.4 million lbs. and had dozens of individual steel plates that were fabricated on site.

A key part of the construction progress was made in late July with the order of the first nuclear fuel load for Unit 3, which consists of 157 fuel assemblies with each measuring 14 ft. tall.

On May 7, Unit 3 was energized (permanently powered), which was essential to perform the testing for the unit. Prior to this, the plant equipment had been running on temporary construction power.

"[This] is a major first step in transitioning the project from construction toward system operations," Chick said.

Construction of the north side of the Unit 3 Auxiliary Building (AB) has progressed with both the floor and roof modules being set. Substantial work also occurred on the steel and concrete that forms the remaining walls and the north AB roof at elevation.

Metering Pilot projects may be good example for Ontario utilities

Ontario Electricity Pricing Pilot Projects explore alternative rates beyond time-of-use, with LDCs and the Ontario Energy Board testing dynamic pricing, demand management, smart-meter billing, and residential customer choice to enhance service and energy efficiency.

 

Key Points

Ontario LDC trials testing alternatives to time-of-use rates to improve billing, demand response, and efficiency.

✅ Data shared across LDCs and Ontario Energy Board provincewide

✅ Tests dynamic pricing, peak/off-peak plans, demand management

✅ Insights to enhance customer choice, bills, and energy savings

 

The results from three electricity pilot projects being offered in southern Ontario will be valuable to utility companies across the province.

Ontario Energy Minister Glenn Thibeault was in Barrie on Tuesday to announce the pilot projects, which will explore alternative pricing plans for electricity customers from three different utility companies, informed by the electricity cost allocation framework guiding rate design.

"Everyone in the industry is watching to see how the pilots deliver.", said Wendy Watson, director of communications for Greater Sudbury Utilities.

"The data will be shared will all the LDCs [local distribution companies] in the province, and probably beyond...because the industry tends to share that kind of information."

Most electricity customers in the province are billed using time-of-use rates, including options like the ultra-low overnight rates that lower costs during off-peak periods, where the cost of electricity varies depending on demand.

The Ontario Energy Board said in a media release that the projects will give residential customers more choice in how much they pay for electricity at different times, reflecting changes for Ontario electricity consumers that expand plan options.

Pilot projects can help improve service

Watson says these kinds of projects give LDCs the chance to experiment and explore new ways of delivering their service, including demand-response initiatives like the Peak Perks program that encourage conservation.

"Any pilot project is a great way to see if in practice if the theory proves out, so I think it's great that the province is supporting these LDCs," she says.

GSU recently completed its own pilot project, the Home Energy Assessment and Retrofit (HEAR) program, which focused on customers who use electric baseboards to heat their homes, amid broader provincial support for electric bills to ease costs."We installed some measures, like programmable thermostats and a few other pieces of equipment into their house," Watson says. "We also made some recommendations about other things that they could do to make their homes more energy efficient."

At the end of the program, GSU provided customers with a report so that they could the see the overall impact on their energy consumption.

Watson says a report on the results of the HEAR program will be released in the near future, for other LDCs interested in new ways to improve their service.

"We think it's incumbent on every LDC...to see what ideas that they can come up with and get approved so they can best serve their customers."

Electricity restored to 75 percent of customers in Puerto Rico

Puerto Rico Power Restoration advances as PREPA, FEMA, and the Army Corps rebuild the grid after Hurricane Maria; 75% of customers powered, amid privatization debate, Whitefish contract fallout, and a continuing island-wide boil-water advisory.

 

Key Points

Effort to rebuild Puerto Rico's grid and restore power, led by PREPA with FEMA support after Hurricane Maria.

✅ 75.35% of customers have power; 90.8% grid generating

✅ PREPA, FEMA, and Army Corps lead restoration work

✅ Privatization debate, Whitefish contract scrutiny

 

Nearly six months after Hurricane Maria decimated Puerto Rico, the island's electricity has been restored to 75 percent capacity, according to its utility company, a contrast to California power shutdowns implemented for different reasons.

The Puerto Rico Electric Power Authority said Sunday that 75.35 percent of customers now have electricity. It added that 90.8 percent of the electrical grid, already anemic even before the Sept. 20 storm barrelled through the island, is generating power again, though demand dynamics can vary widely as seen in Spain's power demand during lockdowns.

Thousands of power restoration personnel made up of the Puerto Rico Electric Power Authority (PREPA), the Federal Emergency Management Agency (FEMA), industry workers from the mainland, and the Army Corps of Engineers have made marked progress in recent weeks, even as California power shutoffs highlight grid risks elsewhere.

Despite this, 65 people in shelters and an island-wide boil water advisory is still in effect even though almost 100 percent of Puerto Ricans have access to drinking water, local government records show.

The issue of power became controversial after Puerto Rico Gov. Ricardo Rossello recently announced plans to privatize PREPA after it chose to allocate a $300 million power restoration contract to Whitefish, a Montana-based company with only a few staffers, rather than put it through the mutual-aid network of public utilities usually called upon to coordinate power restoration after major disasters, and unlike investor-owned utilities overseen by regulators such as the Florida PSC on the mainland.

That contract was nixed and Whitefish stopped working in Puerto Rico after FEMA raised "significant concerns" over the procurement process, scrutiny mirrored by the fallout from Taiwan's widespread outage where the economic minister resigned.

Can California Manage its Solar Boom?

California Duck Curve highlights midday solar oversupply and steep evening peak demand, stressing grid stability. Solutions include battery storage, demand response, diverse renewables like wind, geothermal, nuclear, and regional integration to reduce curtailment.

 

Key Points

A mismatch between midday solar surplus and evening demand spikes, straining the grid without storage and flexibility.

✅ Midday solar oversupply forces curtailment and wasted clean energy.

✅ Evening ramps require fast, fossil peaker plants to stabilize load.

✅ Batteries, demand response, regional trading flatten the curve.

 

California's remarkable success in adopting solar power, including a near-100% renewable milestone, has created a unique challenge: managing the infamous "duck curve." This distinctive curve illustrates a growing mismatch between solar electricity generation and the state's energy demands, creating potential problems for grid stability and ultimately threatening to slow California's progress in the fight against climate change.


The Shape of the Problem

The duck curve arises from a combination of high solar energy production during midday hours and surging energy demand in the late afternoon and evening when solar power declines. During peak solar hours, the grid often has an overabundance of electricity, and curtailments are increasing as a result, while as the sun sets, demand surges when people return home and businesses ramp up operations. California's energy grid operators must scramble to make up this difference, often relying on fast-acting but less environmentally friendly power sources.


The Consequences of the Duck Curve

The increasing severity of the duck curve has several potential consequences for California:

  • Grid Strain: The rapid ramp-up of power sources to meet evening demand puts significant strain on the electrical grid. This can lead to higher operational costs and potentially increase the risk of blackouts during peak demand times.
  • Curtailed Energy: To avoid overloading the grid, operators may sometimes have to curtail excess solar energy during midday, as rising curtailment reports indicate, essentially wasting clean electricity that could have been used to displace fossil fuel generation.
  • Obstacle to More Solar: The duck curve can make it harder to add new solar capacity, as seen in Alberta's solar expansion challenges, for fear of further destabilizing the grid and increasing the need for fossil fuel-based peaking plants.


Addressing the Challenge

California is actively seeking solutions to mitigate the duck curve, aligning with national decarbonization pathways that emphasize practicality. Potential strategies include:

  • Energy Storage: Deploying large-scale battery storage can help soak up excess solar electricity during the day and release it later when demand peaks, smoothing out the duck curve.
  • Demand Flexibility: Encouraging consumers to shift their energy use to off-peak hours through incentives and smart grid technologies can help reduce late-afternoon surges in demand.
  • Diverse Power Sources: While solar is crucial, a balanced mix of energy sources, including geothermal, wind, and nuclear, can improve grid stability and reduce reliance on rapid-response fossil fuel plants.
  • Regional Cooperation: Integrating California's grid with neighboring states can aid in balancing energy supply and demand across a wider geographical area.


The Ongoing Solar Debate

The duck curve has become a central point of debate about the future of California's energy landscape. While acknowledging the challenge, solar advocates argue for continued expansion, backed by measures like a bill to require solar on new buildings, emphasizing the urgent need to transition away from fossil fuels. Grid operators and some utility companies call for a more cautious approach, emphasizing grid reliability and potential costs if the problem isn't effectively managed.


Balancing California's Needs and its Green Ambitions

Finding the right path forward is essential; it will determine whether California can continue to lead the way in solar energy adoption while ensuring a reliable and affordable electricity supply. Successfully navigating the duck curve will require innovation, collaboration, and a strong commitment to building a sustainable energy system, as wildfire smoke impacts on solar continue to challenge generation predictability.
