Self-healing grid technology automatically reroutes power to reduce outages, speed restoration, and boost reliability during storms like Hurricane Ian in Florida, leveraging smart grid sensors, automation, and grid hardening to support Duke Energy customers.

Key Points

Automated smart grid systems that detect faults and reroute power to minimize outages and accelerate restoration.

✅ Cuts outage duration via automated fault isolation

✅ Reroutes electricity with sensors and distribution automation

✅ Supports storm resilience and faster field crew restoration

As Hurricane Ian made its way across Florida, where restoring power in Florida can take weeks in hard-hit areas, Duke Energy's grid improvements were already on the job helping to combat power outages from the storm.

Smart, self-healing technology, similar to smart grid improvements elsewhere, helped to automatically restore more than 160,000 customer outages and saved nearly 3.3 million hours (nearly 200 million minutes) of total lost outage time.

"Hurricane Ian is a strong reminder of the importance of grid hardening and storm preparedness to help keep the lights on for our customers," said Melissa Seixas, Duke Energy Florida state president. "Self-healing technology is just one of many grid improvements that Duke Energy is making to avoid outages, restore service faster and increase reliability for our customers."

Much like the GPS in your car can identify an accident ahead and reroute you around the incident to keep you on your way, self-healing technology is like a GPS for the grid. The technology can quickly identify power outages and alternate energy pathways to restore service faster for customers when an outage occurs.

Additionally, self-healing technology provides a smart tool to assist crews in the field with power restoration after a major storm like Ian, helping reduce outage impacts and freeing up resources to help restore power in other locations.

Three days after Hurricane Ian exited the state, Duke Energy Florida wrapped up restoration of approximately 1 million customers. This progress enabled the company to deploy more than 550 Duke Energy workers from throughout Florida, as well as contractors from across the country, to help restore power for Lee County Electric Cooperative customers.

Crews worked in Cape Coral and Pine Island, one of the hardest-hit areas in the storm's path, as Canadian power crews have in past storms, and completed power restoration for the majority of customers on Pine Island within approximately one week after arriving to the island.

Prior to Ian in 2022, smart, self-healing technology had helped avoid nearly 250,000 extended customer outages in Florida, similar to Hydro One storm recovery efforts, saving around 285,000 hours (17.1 million minutes) of total lost outage time.

Duke Energy currently serves around 59% of customers in Florida with self-healing capabilities on its main power distribution lines, with a goal of serving around 80% over the next few years.

Extreme Heat and Rising Electricity Bills amplify energy costs as climate change drives air conditioning demand, stressing the power grid and energy affordability, with low income households facing outsized burdens during prolonged heat waves.

Key Points

Heat waves from climate change raise AC demand, driving up electricity costs and straining energy affordability.

✅ More AC use spikes electricity demand during heat waves

✅ Low income households face higher energy burden

✅ Grid reliability risks rise with peak cooling loads

Extreme heat waves are not only straining public health systems but also having a significant impact on household finances, particularly through rising electricity bills. According to a recent AP-NORC poll, a growing number of Americans are feeling the financial pinch as soaring temperatures drive up the cost of cooling their homes. This development underscores the broader implications of climate change and its effects on everyday life.

The AP-NORC poll highlights that a majority of Americans are experiencing increased electricity costs as a direct result of extreme heat. As temperatures climb, so does the demand for air conditioning and other cooling systems. This increased energy consumption is contributing to higher utility bills, which can put additional strain on household budgets.

Extreme heat waves have become more frequent and intense due to climate change, which has led to a greater reliance on air conditioning to maintain comfortable indoor environments. Air conditioners and fans work harder during heat waves, and wasteful air conditioning can add around $200 to summer bills, consuming more electricity and consequently driving up energy bills. For many households, particularly those with lower incomes, these increased costs can be a significant burden.

The poll reveals that the impact of rising electricity bills is widespread, affecting a diverse range of Americans. Households across different income levels and geographic regions are feeling the heat, though the extent of the financial strain can vary. Lower-income households are particularly vulnerable, as they often have less flexibility in their budgets to absorb higher utility costs. For these families, the choice between cooling their homes and other essential expenses can be a difficult one.

In addition to financial strain, the poll highlights concerns about energy affordability and access. As electricity bills rise, some Americans may face challenges in paying their bills, leading to potential utility shut-offs or the need to make difficult choices between cooling and other necessities. This situation is exacerbated by the fact that many utility companies do not offer sufficient assistance or relief programs to help low-income households manage their energy costs.

The increasing frequency of extreme heat events and the resulting spike in electricity consumption also have broader implications for the energy infrastructure. Higher demand for electricity can strain power grids, as seen when California narrowly avoided blackouts during extreme heat, potentially leading to outages or reduced reliability. Utilities and energy providers may need to invest in infrastructure upgrades and maintenance to ensure that the grid can handle the increased load during heat waves.

Climate change is a key driver of the rising temperatures that contribute to higher electricity bills. As global temperatures continue to rise, extreme heat events are expected to become more common and severe, and experts warn the US electric grid was not designed to withstand these impacts. This trend underscores the need for comprehensive strategies to address both the causes and consequences of climate change. Efforts to reduce greenhouse gas emissions, improve energy efficiency, and invest in renewable energy sources are critical components of a broader climate action plan.

Energy efficiency measures can play a significant role in mitigating the impact of extreme heat on electricity bills. Upgrading to more efficient cooling systems, improving home insulation, and adopting smart thermostats can help reduce energy consumption and lower utility costs. Additionally, utility companies and government programs can offer incentives and rebates, including ways to tap new funding that help encourage energy-saving practices and support households in managing their energy use.

The poll also suggests that there is a growing awareness among Americans about the connection between climate change and rising energy costs. Many people are becoming more informed about the ways in which extreme weather events and rising temperatures impact their daily lives. This increased awareness can drive demand for policy changes and support for initiatives aimed at addressing climate change and improving energy efficiency, with many willing to contribute income to climate efforts, about the connection between climate change and rising energy costs.

In response to the rising costs and the impact of extreme heat, there are calls for policy interventions and support programs to help manage energy affordability. Proposals include expanding assistance programs for low-income households, investing in infrastructure improvements, and promoting energy efficiency initiatives alongside steps to make electricity systems more resilient to climate risks. By addressing these issues, policymakers can help alleviate the financial burden on households and support a more resilient and sustainable energy system.

Debates over policy impacts on electricity prices continue; in Alberta, federal policies are blamed by some for higher rates, illustrating how regulation can affect affordability.

In conclusion, the AP-NORC poll highlights the growing financial impact of extreme heat on American households, with rising electricity bills being a significant concern for many. The increased demand for cooling during heat waves is straining household budgets and raising broader questions about energy affordability and infrastructure resilience. Addressing these challenges requires a multifaceted approach, including efforts to combat climate change, improve energy efficiency, and provide support for those most affected by rising energy costs. As extreme heat events become more common, finding solutions to manage their impact will be crucial for both individual households and the broader energy system.

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

Spain Electricity Demand April 2020 saw a 17.3% year-on-year drop as COVID-19 lockdown curbed activity; renewables and wind power lifted the emission-free share, while combined cycle plants dominated islands, per REE data.

Key Points

A 17.3% y/y decline amid COVID-19 lockdown, with 47.9% renewables and wind at 21.3% of the national power mix.

✅ Mainland demand -17%; Balearic -27.6%; Canary -20.3%.

✅ Emission-free share: 49.7% on the peninsula in April.

✅ Combined cycle led islands; coal absent in Balearics.

Demand for electricity in Spain dropped by 17.3% year-on-year to an estimated 17,104 GWh in April, aligning with a 15% global daily demand dip during the pandemic, while the country’s economy slowed down under the national state of emergency and lockdown measures imposed to curb the spread of COVID-19.

According to the latest estimates by Spanish grid operator Red Electrica de Espana (REE), the decline in demand was registered across Spain’s entire national territory, similar to a 10% UK drop during lockdown. On the mainland, it decreased by 17% to 16,191 GWh, while on the Balearic and the Canary Islands it plunged by 27.6% and 20.3%, respectively.

Renewables accounted for 47.9% of the total national electricity production in April, echoing Britain’s cleanest electricity trends during lockdown. Wind power production went down 20% year-on-year to 3,730 GWh, representing a 21.3% share in the total power mix.

During April, electricity generation in the peninsula was mostly based on emission-free technologies, reflecting an accelerated power-system transition across Europe, with renewables accounting for 49.7%. Wind farms produced 3,672 GWh, 20.1% less compared to April 2019, while contributing 22% to the power mix, even as global demand later surpassed pre-pandemic levels in subsequent periods.

In the Balearic Islands, electricity demand of 323,296 MWh was for the most part met by combined cycle power plants, even as some European demand held firm in later lockdowns, which accounted for 78.3% of the generation. Renewables and emission-free technologies had a combined share of 6.4%, while coal was again absent from the local power mix, completing now four consecutive months without contributing a single MWh.

In the Canary Islands system, demand for power decreased to 558,619 MWh, even as surging demand elsewhere strained power systems across the world. Renewables and emission-free technologies made up 14.3% of the mix, while combined cycle power plants led with a 45.3% share.

Ontario Pickering Nuclear Closure will shift supply to natural gas, raising emissions as the electricity grid manages nuclear refurbishment, IESO planning, clean power imports, and new wind, solar, and storage to support electrification.

Key Points

Ontario will close Pickering and rely on natural gas, increasing emissions while other nuclear units are refurbished.

✅ 14% of Ontario electricity supplied by Pickering now

✅ Natural gas use rises; grid emissions projected up 375%

✅ IESO warns gas phaseout by 2030 risks blackouts, costs

The Ontario government will not reconsider plans to close the Pickering nuclear station and instead stop-gap the consequent electricity shortfall with natural gas-generated power in a move that will, as an analysis of Ontario's grid shows, hike the province’s greenhouse gas emissions substantially in the coming years.

In a report released this week, a nuclear advocacy group urged Ontario to refurbish the aging facility east of Toronto, which is set to be shuttered in phases in 2024 and 2025, prompting debate over a clean energy plan after Pickering as the closure nears. The closure of Pickering, which provides 14 per cent of the province’s annual electricity supply, comes at the same time as Ontario’s other two nuclear stations are undergoing refurbishment and operating at reduced capacity.

Canadians for Nuclear Energy, which is largely funded by power workers' unions, argued closing the 50-year-old facility will result in job losses, emissions increases, heightened reliance on imported natural gas and an electricity supply gap across Ontario.

But Palmer Lockridge, spokesperson for the provincial energy minister, said further extending Pickering’s lifespan isn’t on the table.

“As previously announced in 2020, our government is supporting Ontario Power Generation’s plan to safely extend the life of the Pickering Nuclear Generating Station through the end of 2025,” said Lockridge in an emailed response to questions.

“Going forward, we are ensuring a reliable, affordable and clean electricity system for decades to come. That’s why we put a plan in place that ensures we are prepared for the emerging energy needs following the closure of Pickering, and as a result of our government’s success in growing and electrifying the province’s economy.”

The Progressive Conservative government under Premier Doug Ford has invested heavily in electrification, sinking billions into electric vehicle and battery manufacturing and industries like steel-making to retool plants to run on electricity rather than coal, and exploring new large-scale nuclear plants to bolster baseload supply.

Natural gas now provides about seven per cent of the province’s energy, a piece of the pie that will rise significantly as nuclear energy dwindles. Emissions from Ontario’s electricity grid, which is currently one of the world’s cleanest with 94 per cent zero-emission power generation, are projected to rise a whopping 375 per cent as the province turns increasingly to natural gas generation. Those increases will effectively undo a third of the hard-won emissions reductions the province achieved by phasing out coal-fired power generation.

The Independent Electricity System Operator (IESO), which manages Ontario’s grid, studied whether the province could phase out natural gas generation by 2030 and concluded that “would result in blackouts and hinder electrification” and increase average residential electricity costs by $100 per month.

The Ontario Clean Air Alliance, however, obtained draft documents from the electricity operator that showed it had studied, but not released publicly, other scenarios that involved phasing out natural gas without energy shortfalls, price hikes or increases in emissions.

The Ontario government will not reconsider plans to close the Pickering nuclear station and instead stop-gap the consequent electricity shortfall facing Ontario with natural gas-generated power in a move that will hike the province’s greenhouse gas emissions.

One model suggested increasing carbon taxes and imports of clean energy from other provinces could keep blackouts, costs and emissions at bay, while another involved increasing energy efficiency, wind generation and storage.

“By banning gas-fired electricity exports to the U.S., importing all the Quebec water power we can with the existing transmission lines and investing in energy efficiency and wind and solar and storage — do all those things and you can phase out gas-fired power and lower our bills,” said Jack Gibbons, chair of the Ontario Clean Air Alliance.

The IESO has argued in response that the study of those scenarios was not complete and did not include many of the challenges associated with phasing out natural gas plants.

Ontario Energy Minister Todd Smith asked the IESO to develop “an achievable pathway to zero-emissions in the electricity sector and evaluate a moratorium on new-build natural gas generation stations,” said his spokesperson. That report, an early look at halting gas power, is expected in November.
