ComEd Hosting Capacity Map helps Illinois communities assess photovoltaic capacity, distributed energy resources, interconnection limits, and grid planning needs, guiding developers and policymakers on siting solar, net metering feasibility, and RPS-aligned deployment by circuit.

 

Key Points

An online tool showing circuit-level DER capacity, PV limits, and interconnection readiness across ComEd.

✅ Circuit-level estimates of solar hosting capacity

✅ Guides siting, interconnection, and net metering

✅ Supports RPS goals with grid planning insights

 

As the Illinois solar market grows from the Future Energy Jobs Act, the largest utility in the state has posted a planning tool to identify potential PV capacity in their service territory. ComEd, a Northern Illinois subsidiary of Exelon, has a hosting capacity website for its communities indicating how much photovoltaic capacity can be sited in given areas, based on the existing electrical infrastructure, as utilities pilot virtual power plant programs that leverage distributed resources.

According to ComEd’s description, “Hosting Capacity is an estimate of the amount of DER [distributed energy resources] that may be accommodated under current configurations at the overall circuit level without significant system upgrades to address adverse impacts to power quality or reliability.” This website will enable developers and local decision makers to estimate how much solar could be installed by township, sections and fractions of sections as small as ½ mile by ½ mile and to gauge EV charging impacts with NREL's projection tool for distribution planning. The map sections indicate potential capacity by AC kilowatts with a link to to ComEd’s recently upgraded Interconnection and Net Metering homepage.

The Hosting Map can provide insight into how much solar can be installed in which locations in order to help solar reach a significant portion of the Illinois Renewable Portfolio Standard (RPS) of 25% electricity from renewable sources by 2025, and to plan for transportation electrification as EV charging infrastructure scales across utility territories. For example, the 18 sections of Oak Park Township capacity range from 612 to 909 kW, and total 13,260 kW of photovoltaic power. That could potentially generate around 20 million kWh, and policy actions such as the CPUC-approved PG&E EV program illustrate how electrification initiatives may influence future demand. Oak Park, according to the PlanItGreen Report Card, a joint project of the Oak Park River Forest Community Foundation and Seven Generations Ahead, uses about 325 million kWh.

Based on ComEd’s Hosting Capacity, Oak Park could generate about 6% of its electricity from solar power located within its borders. Going significantly beyond this amount would likely require a combination of upgrades by ComEd’s infrastructure, potentially higher interconnection costs and deployment of technologies like energy storage solutions. What this does indicate is that a densely populated community like Oak Park would most likely have to get the majority of its solar and renewable electricity from outside its boundaries to reach the statewide RPS goal of 25%. The Hosting Capacity Map shows a considerable disparity among communities in ½ mile by ½ mile sections with some able to host only 100-200 kWs to some with capacities of over 3,000 kW.

Electricity sales in the U.S. actually dropped over the past 7 years

US Electricity Sales Decline amid population growth and GDP gains, as DOE links reduced per capita consumption to energy efficiency, warmer winters, appliances, and bulbs, while hotter summers and rising AC demand may offset savings.

 

Key Points

US electricity sales fell 3% since 2010 despite population and GDP growth, driven by efficiency gains and warmer winters.

✅ DOE links drops to efficiency and warmer winters

✅ Per capita residential use fell about 7% since 2010

✅ Rising AC demand may offset winter heating savings

 

Since 2010, the United States has grown by 17 million people, and the gross domestic product (GDP) has increased by $3.6 trillion. Yet in that same time span, electricity sales in the United States actually declined by 3%, according to data released by the U.S. Department of Energy (DOE), even as electricity prices rose at a 41-year pace nationwide.

The U.S. decline in electricity sales is remarkable given that the U.S. population increased by 5.8% in that same time span. This means that per capita electricity use fell even more than that; indeed, the Department of Energy pegs residential electricity sales per capita as having declined by 7%, even as inflation-adjusted residential bills rose 5% in 2022 nationwide.

There are likely multiple reasons for this decline in electricity sales. Department of Energy analysts suggest that, at least in part, it is due to increased adoption of energy-efficient appliances and bulbs, like compact fluorescents. Indeed, the DOE notes that there is a correlation between consumer spending on “energy efficiency” and a reduction in per capita electricity sales, while utilities invest more in delivery infrastructure to modernize the grid.

Yet the DOE also notes that states with a greater increase in warm weather days had a corresponding decrease in electricity sales, as milder weather can reduce power demand across years. In southern states, the effect was most dramatic: for instance, from 2010 to 2016, Florida had a 56% decrease in cold weather days that would require heating and as a result, saw a 9% decrease in per capita electricity sales.

The moral is that warm winters save on electricity. But if global temperatures continue to rise, and summers become hotter, too, this decrease in winter heating spending may be offset by the increased need to run air conditioning in the summer, and given how electricity and natural gas prices interact, overall energy costs could shift. Indeed, it takes far more energy to cool a room than it does to heat it, for reasons related to the basic laws of thermodynamics.

Yale Report on Western Grid Integration: Just Say Yes

Western Grid Integration aligns CAISO with a regional transmission operator under FERC oversight, boosting renewables, reliability, and cost savings while respecting state energy policy, emissions goals, and utility regulation across the West.

 

Key Points

Western Grid Integration lets CAISO operate under FERC to cut costs, boost reliability, and accelerate renewables.

✅ Lowers wholesale costs via wider dispatch and resource sharing

✅ Improves reliability with regional balancing and reserves

✅ Preserves state policy authority under FERC oversight

 

A strong and timely endorsement for western grid integration forcefully rebuts claims that moving from a balkanized system with 38 separate entities to a regional operation could introduce environmental problems, raise costs, or, as critics warn, export California’s energy policies to other western states, or open state energy and climate policies to challenge by federal regulators. In fact, Yale University’s Environmental Protection Clinic identifies numerous economic and environmental benefits from allowing the California Independent System Operator to become a regional grid operator.

The groundbreaking report comprehensively examines the policy and legal merits of allowing the California Independent System Operator (CAISO) to become a regional grid operator, open to any western utility or generator that wants to join, as similar market structure overhauls proceed in New England.

The Yale report identifies the increasing constraints that today’s fragmented western grid imposes on system-wide electricity costs and reliability, addresses the potential benefits of integration, and evaluates  potential legal risks for the states involved. California receives particular attention because its legislature is considering the first step in the grid integration process, which involves authorizing the CAISO to create a fully independent board, even as it examines revamping electricity rates to clean the grid (other western states are unlikely to approve joining an entity whose governance is determined solely by California’s governor and legislature, as is the case now).

 

Elements of the report

The analysis examined all of California’s key energy and climate policies, from its cap on carbon emissions to its renewable energy goals and its pollution standards for power plants, and concludes that none would face additional legal risks under a fully integrated western grid. The operator of such a grid would be regulated by an independent federal agency (the Federal Energy Regulatory Commission)—but so is the CAISO itself, now and since its inception, by virtue of its extended involvement in interstate electricity commerce throughout the West. 

And if empowered to serve the entire region, the CAISO would not interfere with the longstanding rights of California and other states to regulate their utilities’ investments or set energy and climate policies. The study points out that grid operators don’t set energy policies for the states they serve; they help those states minimize costs, enhance reliability in the wake of California blackouts across the state, and avoid unnecessary pollution.

And as to whether an integrated grid would help renewable energy or fossil fuels, the report finds that renewable resources would be the inevitable winners, thanks to their lower operating costs, although the most important winners would be western utility customers, through lower bills, expanded retail choice options, and improved reliability.

 

Call to action

The Yale report concludes with what amounts to a call to action for California’s legislators:

“In sum, enhanced Western grid integration in general, and the emergence of a regional system operator in particular, would not expose California’s clean energy policies to additional legal risks. Shifting to a regional grid operator would enable more efficient, affordable and reliable integration of renewable resources without increasing the legal risk to California’s clean energy policies.”

The authors of the analysis, from the Yale Law School and the Yale School of Forestry and Environmental Studies, are Juliana Brint, Josh Constanti, Franz Hochstrasser. and Lucy Kessler. They dedicated months to the project, consulted with a diverse group of reviewers, and made the trek from New Haven to Folsom, CA, to visit the California Independent System Operator and interview key staff members.

BC Hydro hoping to be able to charge customers time of use rates

BC Hydro Time-of-Use Rates propose off-peak credits and peak surcharges, with 5 cent/kWh differentials, encouraging demand shifting, EV charging at night, and smart meter adoption, pending BC Utilities Commission review in an optional opt-in program.

 

Key Points

Optional pricing that credits 5 cents/kWh off-peak and adds 5 cents/kWh during 4-9 p.m. peak to encourage load shifting.

✅ Off-peak credit: 11 p.m.-7 a.m., 5 cents/kWh savings

✅ Peak surcharge: 4-9 p.m., additional 5 cents/kWh

✅ Opt-in only; BCUC review; suits EV charging and flexible loads

 

BC Hydro is looking to charge customers less for electricity during off peak hours and more during the busiest times of the day, reflecting holiday electricity demand as well.

The BC Utilities Commission is currently reviewing the application that if approved would see customers receive a credit of 5 cents per kilowatt hour for electricity used from 11 p.m. to 7 a.m.

Customers would be charged an additional 5 cents per kWh for electricity used during the on-peak period from 4 p.m. to 9 p.m., and in Ontario, there were no peak-rate cuts for self-isolating customers during early pandemic response.

There would be no credit or additional charge will be applied to usage during the off-peak period from 7 a.m. to 4 p.m. and 9 p.m. to 11 p.m.

“We know the way our customers are using power is changing and they want more options,” BC Hydro spokesperson Susie Rieder said.

“It is optional and we know it may not work for everyone.”

For example, if a customer has an electric vehicle it will be cheaper to plug the car in after 9 p.m., similar to Ontario's ultra-low overnight plan offerings, rather than immediately after returning home from a standard work day.

If approved, the time of use rates would only apply to customers who opt in to the program, whereas Ontario provided electricity relief during COVID-19.

During the pandemic, Ontario extended off-peak electricity rates to help households and small businesses.

The regulatory review process is expected to take about one year.

Other jurisdictions, including Ontario's ultra-low overnight pricing, currently offer off peak rates. One of the challenges is that consumers change in hopes of altering their behaviour, but in reality, end up paying more.

“The cheapest electrical grid system is one with consistent demand and the issue of course is our consumption is not flat,” energyrates.ca founder Joel MacDonald said.

“There is a 5 cent reduction in off peak times, there is a 5 cent increase in peak times, you would have to switch 50 per cent of your load.”

Symantec Proves Russian

Dragonfly energy sector cyberattacks target ICS and SCADA across critical infrastructure, including the power grid and nuclear facilities, using spearphishing, watering-hole sites, supply-chain compromises, malware, and VPN exploits to gain operational access.

 

Key Points

Dragonfly APT campaigns target energy firms and ICS to gain grid access, risking manipulation and service disruption.

✅ Breaches leveraged spearphishing, watering-hole sites, and supply chains.

✅ Targeted ICS, SCADA, VPNs to pivot into operational networks.

✅ Aimed to enable power grid manipulation and potential outages.

 

An October, 2017 report by researchers at Symantec Corp., cited by the U.S. government, has linked recent US power grid cyber attacks to a group of hackers it had code-named "Dragonfly", and said it found evidence critical infrastructure facilities in Turkey and Switzerland also had been breached.

The Symantec researchers said an earlier wave of attacks by the same group starting in 2011 was used to gather intelligence on companies and their operational systems. The hackers then used that information for a more advanced wave of attacks targeting industrial control systems that, if disabled, leave millions without power or water.

U.S. intelligence officials have long been concerned about the security of the country’s electrical grid. The recent attacks, condemned by the U.S. government, striking almost simultaneously at multiple locations, are testing the government’s ability to coordinate an effective response among several private utilities, state and local officials, and industry regulators.

While the core of a nuclear generator is heavily protected, a sudden shutdown of the turbine can trigger safety systems. These safety devices are designed to disperse excess heat while the nuclear reaction is halted, but the safety systems themselves may be vulnerable to attack.

The operating systems at nuclear plants also tend to be legacy controls built decades ago and don’t have digital control systems that can be exploited by hackers.

“Since at least March 2016, Russian government cyber actors… targeted government entities and multiple U.S. critical infrastructure sectors, including the energy, nuclear, commercial facilities, water, aviation, and critical manufacturing sectors,” according to Thursday’s FBI and Department of Homeland Security report. The report did not say how successful the attacks were or specify the targets, but said that the Russian hackers “targeted small commercial facilities’ networks where they staged malware, conducted spearphishing, and gained remote access into energy sector networks.” At least one target of a string of infrastructure attacks last year was a nuclear power facility in Kansas.

Symantec doesn’t typically point fingers at particular nations in its research on cyberattacks, said Eric Chien, technical director of Symantec’s Security Technology and Response division, though he said his team doesn’t see anything it would disagree with in the new federal report. The government report appears to corroborate Symantec’s research, showing that the hackers had penetrated computers and accessed utility control rooms that would let them directly manipulate power systems, he says.

“There were really no more technical hurdles for them to do something like flip off the power,” he said.

And as for the group behind the attacks, Chien said it appears to be relatively dormant for now, but it has gone quiet in the past only to return with new hacks.

“We expect they’re sort of retooling now, and they likely will be back,”

 


 

In some cases, Dragonfly successfully broke into the core systems that control US and European energy companies, Symantec revealed.

“The energy sector has become an area of increased interest to cyber-attackers over the past two years,” Symantec said in its report.

“Most notably, disruptions to Ukraine’s power system in 2015 and 2016 were attributed to a cyberattack and led to power outages affecting hundreds of thousands of people. In recent months, there have also been media reports of attempted attacks on the electricity grids in some European countries, as well as reports of companies that manage nuclear facilities in the US being compromised by hackers.

“The Dragonfly group appears to be interested in both learning how energy facilities operate and also gaining access to operational systems themselves, to the extent that the group now potentially has the ability to sabotage or gain control of these systems should it decide to do so. Symantec customers are protected against the activities of the Dragonfly group.”

In recent weeks, senior US intelligence officials said that the Kremlin believes it can launch hacking operations against the West with impunity, including a cyber weapon that can disrupt power grids, according to assessments.

The DHS and FBI report further elaborated: “This campaign comprises two distinct categories of victims: staging and intended targets. The initial victims are peripheral organisations such as trusted third-party suppliers with less-secure networks, referred to as ‘staging targets’ throughout this alert.

“The threat actors used the staging targets’ networks as pivot points and malware repositories when targeting their final intended victims. National Cybersecurity and Communications Integration Center and FBI judge the ultimate objective of the actors is to compromise organisational networks, also referred to as the ‘intended target’.”

According to the US alert, hackers used a variety of attack methods, including spear-phishing emails, watering-hole domains, credential gathering, open source and network reconnaissance, host-based exploitation, and deliberate targeting of ICS infrastructure.

The attackers also targeted VPN software and used password cracking tools.

Once inside, the attackers downloaded tools from a remote server and then carried out a number of actions, including modifying key systems to store plaintext credentials in memory, and built web shells to gain command and control of targeted systems.

“This actors’ campaign has affected multiple organisations in the energy, nuclear, water, aviation, construction and critical manufacturing sectors, with hundreds of victims across the U.S. power grid confirmed,” the DHS said, before outlining a number of steps that IT managers in infrastructure organisations can take to cleanse their systems and defend against Russian hackers. he said.

Russia-Ukraine Agreement on Power Plant Attacks Possible

Russia-Ukraine Energy Ceasefire explores halting strikes on power plants, safeguarding energy infrastructure and grids, easing humanitarian crises, stabilizing European markets, and advancing diplomatic talks on security, resilience, and critical infrastructure protection.

 

Key Points

A proposed pact to halt strikes on power plants, protect energy infrastructure, and stabilize grids and security.

✅ Shields power plants and grid infrastructure from attacks

✅ Eases humanitarian strain and improves winter resilience

✅ Supports European energy security and market stability

 

In a significant diplomatic development amid ongoing conflict, Russia and Ukraine are reportedly exploring the possibility of reaching an agreement to halt attacks on each other’s power plants. This potential cessation of hostilities could have far-reaching implications for the energy security and stability of both nations, as well as for the broader European energy landscape.

The Context of Energy Warfare

The conflict between Russia and Ukraine has escalated into what many analysts term "energy warfare," where both sides have targeted each other’s energy infrastructure. Such actions not only aim to undermine the adversary’s military capabilities but also have profound effects on civilian populations, leading to widespread power outages and humanitarian crises. Energy infrastructure has become a focal point in the conflict, with power plants and grids frequently damaged or destroyed.

The ongoing hostilities have raised concerns about energy security in Europe, with some warning of an energy nightmare if disruptions escalate, especially as many countries in the region rely on energy supplies from Russia. The attacks on power facilities exacerbate vulnerabilities in the energy supply chain, prompting calls for a ceasefire that encompasses energy infrastructure.

The Humanitarian Implications

The humanitarian impact of the conflict has been staggering, with millions of civilians affected by power outages, heating shortages, and disrupted access to essential services. The winter months, in particular, pose a grave challenge, as Ukraine prepares for winter amid ongoing energy constraints for vulnerable populations. A potential agreement to cease attacks on power plants could provide much-needed relief and stability for civilians caught in the crossfire.

International organizations, including the United Nations and various humanitarian NGOs, have been vocal in urging both parties to prioritize civilian safety and to protect critical infrastructure. Any agreement reached could facilitate aid efforts and enhance the overall humanitarian situation in affected areas.

Diplomatic Efforts and Negotiations

Reports indicate that diplomatic channels are being utilized to explore this potential agreement. While the specifics of the negotiations remain unclear, the idea of protecting energy infrastructure has been gaining traction among international diplomats. Key players, including European nations and the United States, with debates over U.S. energy security shaping positions, may play a pivotal role in mediating discussions.

Negotiating a ceasefire concerning energy infrastructure could serve as a preliminary step toward broader peace talks. By demonstrating goodwill through a tangible agreement, both parties might foster an environment conducive to further negotiations on other contentious issues in the conflict.

The Broader European Energy Landscape

The ramifications of an agreement between Russia and Ukraine extend beyond their borders. The stability of energy supplies in Europe is inextricably linked to the dynamics of the conflict, and the posture of certain EU states, such as Hungary's energy alliance with Russia, also shapes outcomes across the region. Many European nations have been grappling with rising energy prices and supply uncertainties, particularly in light of reduced gas supplies from Russia.

A halt to attacks on power plants could alleviate some of the strain on energy markets, which have experienced price hikes and instability in recent months, helping to stabilize prices and improve energy security for neighboring countries. Furthermore, it could pave the way for increased cooperation on energy issues, such as joint projects for renewable energy development or grid interconnections.

Future Considerations

While the prospect of an agreement is encouraging, skepticism remains about the willingness of both parties to adhere to such terms. The historical context of mistrust and previous violations of ceasefires, as both sides have accused each other of violations in recent months, raises questions about the durability of any potential pact. Continued dialogue and monitoring by international entities will be essential to ensure compliance and to build confidence between the parties.

Moreover, as discussions progress, it will be crucial to consider the long-term implications for energy policy in both Russia and Ukraine. The conflict has already prompted Ukraine to seek alternative energy sources and reduce its dependence on Russian gas, turning to electricity imports to keep the lights on, while Russia is exploring new markets for its energy exports.

The potential agreement between Russia and Ukraine to stop targeting each other’s power plants represents a glimmer of hope in a protracted conflict characterized by violence and humanitarian suffering. As both nations explore this diplomatic avenue, the implications for energy security, civilian safety, and the broader European energy landscape could be profound. Continued international support and monitoring will be vital to ensure that any agreement reached translates into real-world benefits for affected populations and contributes to a more stable energy future for the region.

Electric Utilities Plot Bullish Course for EV Charging Infrastructure

EV Charging Infrastructure Incentives are expanding as utilities fund public chargers, Level 2 networks, DC fast charging, grid-managed off-peak programs, and equitable access across Ohio, New Jersey, and Florida to accelerate clean transportation.

 

Key Points

Utility-backed programs funding Level 2 and DC fast chargers, managing grid demand, and expanding EV equity.

✅ Incentives for Level 2 and DC fast public charging stations.

✅ Grid-friendly off-peak charging to balance demand.

✅ Equity targets place chargers in low-income communities.

 

Electric providers in Florida, Ohio and New Jersey recently announced plans to expand electric vehicle charging networks and infrastructure through various incentive programs that could add thousands of new public chargers in the next several years.

Elsewhere, utilities are advancing similar efforts, with Michigan EV programs proposing more than $20 million for charging infrastructure to accelerate adoption.

American Electric Power in Ohio will offer nearly $10 million in incentives toward the build out of 375 EV charging stations throughout the company's service territory, which largely includes Columbus.

Meanwhile, the Public Service Electric and Gas Company (PSE&G), an electric utility provider in New Jersey, has proposed a six-year plan to support the development of nearly 40,000 electric vehicle chargers across a wide range of customers and sectors, said Francis Sullivan, a spokesperson for PSE&G.

And Duke Energy in Florida is installing up to 530 EV charging stations across its service area, as part of its Park and Plug pilot program, which will be making the charging ports available in multifamily housing complexes, workplaces and other high traffic areas.

"We are bringing cleaner energy to Florida through 700 megawatts of new universal solar, and we are helping our customers to bring clean transportation to the state as well," Catherine Stempien, Duke Energy Florida president, said in a statement. "We are committed to providing smarter, cleaner energy alternatives for all our customers."

The project in Ohio is making incentive funding available to government organizations, multifamily housing developments and workplaces, covering from 50 percent to all of the costs. The plan, to be rolled out in the next four years, aims to incentivize the development of 300 level-two chargers and 75 "fast chargers" capable of charging a car's battery in minutes rather than hours.

"I think what's interesting about what we're seeing now in the industry is that electric vehicles and electric vehicle charging are expanding beyond California, and like other Pacific Coast states," said Scott Fisher, vice president of marketing at Greenlots, maker of car chargers and software. Greenlots has been selected as one of the companies to provide the chargers for the AEP project.

California has occupied the lion's share of the electric vehicle market, making up about 5 percent of the cars on the state's highways. The U.S. market sits at about 1.5 percent. However, indications show the EV boom may be set to take off as more models are being rolled out, and prices are making the electric cars more competitive with their gas-powered counterparts. The group Securing America's Future Energy (SAFE) announced the one-millionth electric vehicle is on course to be sold in the United States this month.

In a statement, Ben Prochazka, vice president of the Electrification Coalition, an EV advocacy group, called this "a major milestone and brings us one step closer to reducing our transportation system's dependence on oil. This is a direct result of the tireless efforts by communities and advocates throughout the 'EV ecosystem.'"

In New Jersey, PSE&G's efforts -- which are part of the company's proposed Clean Energy Future program -- will not only focus on building out the charging infrastructure, but structure car recharging to control charging and encourage residents to charge their cars during off-peak times.

"For now, with a modest number of charging stations in the market, it's not a huge problem. But over time, as you're putting in many thousands of these stations, what you want to make sure is that those stations are operating in sync with state power grids, where you don't have people all charging at the same time at like 5 p.m. on a hot summer day," said Fisher.

PSE&G also plans to offer incentives to encourage the development of level-two chargers and DC fast-chargers, as well as "provide grants and incentives for 100 electric school buses and EV charging infrastructure at school districts in PSE&G's service territory," said Sullivan.

"PSE&G will also help fund electrification projects at customer locations such as ports, airports and transit facilities," Sullivan added, via email.

Utilities and transportation planners are also keeping the concept of equity in mind -- to ensure EVs are adopted by more than just the Tesla owner -- and will also focus on placing infrastructure in low-income areas.

"Ten percent of the stations will be in low income areas, defined by census blocks," said Scott Blake, a communications consultant at AEP in Columbus.

Duke Energy also announced 10 percent of the chargers it is installing in Florida will be in "income-qualified communities," according to a company press release.
