Hydro One wants to spend another $6-million to redesign bills

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.

Massachusetts Solar Net Metering faces new demand charges and elimination of residential time-of-use rates under an MDPU order, as Eversource cites grid cost fairness while clean energy advocates warn of impacts on distributed solar growth.

Key Points

Policy letting solar customers net out usage with exports; MDPU now adds demand charges and ends TOU rates.

✅ New residential solar demand charges start Dec 31, 2018.

✅ Optional residential TOU rates eliminated by MDPU order.

✅ Eversource cites grid cost fairness; advocates warn slower solar.

A recent Massachusetts Department of Public Utilities' rate case order changes the way solar net metering works and eliminates optional residential time-of-use rates, stirring controversy between clean energy advocates and utility Eversource and potential consumer backlash over rate design.

"There is a lot of room to talk about what net-energy metering should look like, but a demand charge is an unfair way to charge customers," Mark LeBel, staff attorney at non-profit clean energy advocacy organization Acadia Center, said in a Tuesday phone call. Acadia Center is an intervenor in the rate case and opposed the changes.

The Friday MDPU order implements demand charges for new residential solar projects starting on December 31, 2018. Such charges are based on the highest peak hourly consumption over the course of a month, regardless of what time the power is consumed.

Eversource contends the demand charge will more fairly distribute the costs of maintaining the local power grid, echoing minimum charge proposals aimed at low-usage customers. Net metering is often criticized for not evenly distributing those costs, which are effectively subsidized by non-net-metered customers.

"What the demand charge will do is eliminate, to the extent possible, the unfair cross subsidization by non-net-metered customers that currently exists with rates that only have kilowatt-hour charges and no kilowatt demand, Mike Durand, Eversource spokesman, said in a Tuesday email. 

"For net metered facilities that use little kilowatt-hours, a demand charge is a way to charge them for their fair share of the cost of the significant maintenance and upgrade work we do on the local grid every day," Durand said. "Currently, their neighbors are paying more than their share of those costs."

It will not affect existing facilities, Durand said, only those installed after December 31, 2018.

Solar advocates are not enthusiastic about the change and see it slowing the growth of solar power, particularly residential rooftop solar, in the state.

"This is a terrible outcome for the future of solar in Massachusetts," Nathan Phelps, program manager of distributed generation and regulatory policy at solar power advocacy group Vote Solar, said in a Tuesday phone call.

"It's very inconsistent with DPU precedent and numerous pieces of legislation passed in the last 10 years," Phelps said. "The commonwealth has passed several pieces of legislation that are supportive of renewable energy and solar power. I don't know what the DPU was thinking."

 

TIME-OF-USE PRICING ELIMINATED

It does not matter when during the month peak demand occurs -- which could be during the week in the evening -- customers will be charged the same as they would on a hot summer day, LeBel said. Because an individual customer's peak usage does not necessarily correspond to peak demand across the utility's system, consumers are not being provided incentives to reduce energy usage in a way that could benefit the power system, Acadia Center said in a Tuesday statement.

However, Eversource maintains that residential customer distribution peaks based on customer load profiles do not align with basic service peak periods, which are based on Independent System Operator New England's peaks that reflect market-based pricing, even as a Connecticut market overhaul advances in the region, according to the MDPU order.

"The residential Time of Use rates we're eliminating are obsolete, having been designed decades ago when we were responsible for both the generation and the delivery of electricity," Eversource's Durand said.

"We are no longer in the generation business, having divested of our generation assets in Massachusetts in compliance with the law that restructured of our industry back in the late 1990s. Time Varying pricing is best used with generation rates, where the price for electricity changes based on time of day and electricity demand and can significantly alter electric bills for households," he said.

Additionally, only 0.02% of residential customers take service on Eversource's TOU rates and it would be difficult for residential customers to avoid peak period rates because they do not have the ability to shift or reduce load, according to the order.

"The Department allowed the Companies' proposal to eliminate their optional residential TOU rates in order to consolidate and align their residential rates and tariffs to better achieve the rate structure goal of simplicity," the MDPU said in the order.

EV-Driven Electricity Demand Growth will reshape utilities through electrification, EV adoption, grid modernization, and ratebasing of charging, as NREL forecasts rising terawatt-hours, CAGR increases, and demand-side flexibility to manage emissions and reliability.

Key Points

Growth in power consumption fueled by EV adoption and electrification, increasing utility sales and grid investment.

✅ NREL projects 20%-38% higher U.S. load by 2050

✅ Utilities see CAGR up to 1.6% and 80 TWh/year growth

✅ Demand-side flexibility and EV charging optimize grids

Utilities have struggled with flat demand for years, but analysis by the National Renewable Energy Laboratory predicts steady growth across the next three decades — largely driven by the adoption of electric vehicles, including models like the Tesla Model 3 that are reshaping expectations.

The study considers three scenarios, a reference case and medium- and high-adoption electrification predictions. All indicate demand growth, but in the medium and high scenarios for 2050, U.S. electricity consumption increases by 20% and 38%, respectively, compared to business as usual.

Utilities could go from stagnant demand to compound annual growth rates of 1.6%, which would amount to sustained absolute growth of 80 terawatt-hours per year.

"This unprecedented absolute growth in annual electricity consumption can significantly alter supply-side infrastructure development requirements," the report says, and could challenge state power grids in multiple regions.

NREL's Trieu Mai, principal investigator for the study, cautions that more research is needed to fully assess the drivers and impacts of electrification, "as well as the role and value of demand-side flexibility."

"Although we extensively and qualitatively discuss the potential drivers and barriers behind electric technology adoption in the report, much more work is needed to quantitatively understand these factors," Mai said in a statement.

However, utilities have largely bought into the dream.

"Electric vehicles are the biggest opportunity we see right now," Energy Impact Partners CEO Hans Kobler told Utility Dive. And the impact could go beyond just higher kilowattt-hour sales, particularly as electric truck fleets come online.

"When the transportation sector is fully electrified, it will result in around $6 trillion in investment," Kobler said. "Half of that is on the infrastructure side of the utility." And the industry can also benefit through ratebasing charging stations and managing the new demand.

One benefit that NREL's report points to is the possibility of "expanded value streams enabled by electric and/or grid-connected technologies," such as energy storage and mobile chargers that enhance flexibility.

"Many electric utilities are carefully watching the trend toward electrification, as it has the potential to increase sales and revenues that have stagnated or fallen over the past decade," the report said, highlighting potential benefits for all customers as adoption grows. "Beyond power system planning, other motivations to study electrification include its potential to impact energy security, emissions, and innovation in electrical end-use technologies and overall efficient system integration. The impacts of electrification could be far-reaching and have benefits and costs to various stakeholders."

Canada Electricity Grid Decarbonization advances net-zero goals by expanding renewable energy (wind, solar, hydro), boosting grid reliability with battery storage, and aligning policy, efficiency, and investment to cut emissions and strengthen energy security.

Key Points

Canada's shift to low-carbon power using renewables and storage to cut emissions and improve grid reliability.

✅ Invest in wind, solar, hydro, and transmission upgrades

✅ Deploy battery storage to balance intermittent generation

✅ Support just transition, jobs, and energy efficiency

As Canada moves towards a more sustainable future, decarbonizing its electricity grid has emerged as a pivotal goal. The transition aims to reduce greenhouse gas emissions, promote renewable energy sources, and ultimately support global climate targets, with cleaning up Canada's electricity widely viewed as critical to meeting those pledges. However, the implications of this transition are multifaceted, impacting the economy, energy reliability, and the lives of Canadians.

Understanding Decarbonization

Decarbonization refers to the process of reducing carbon emissions produced from various sources, primarily fossil fuels. In Canada, the electricity grid is heavily reliant on natural gas, coal, and oil, which contribute significantly to carbon emissions. The Canadian government has committed to achieving net-zero by 2050 through federal and provincial collaboration, with the electricity sector playing a crucial role in this initiative. The strategy includes increasing the use of renewable energy sources such as wind, solar, and hydroelectric power.

Economic Considerations

Transitioning to a decarbonized electricity grid presents both challenges and opportunities for Canada’s economy. On one hand, the initial costs of investing in renewable energy infrastructure can be substantial. This includes not only the construction of renewable energy plants but also the necessary upgrades to the grid to accommodate new technologies. According to the Fraser Institute analysis, these investments could lead to increased electricity prices, impacting consumers and businesses alike.

However, the shift to a decarbonized grid can also stimulate economic growth. The renewable energy sector is a rapidly growing industry that, as Canada’s race to net-zero accelerates, promises job creation in manufacturing, installation, and maintenance of renewable technologies. Moreover, as technological advancements reduce the cost of renewable energy, the long-term savings on fuel costs can benefit both consumers and businesses. The challenge lies in balancing these economic factors to ensure a smooth transition.

Reliability and Energy Security

A significant concern regarding the decarbonization of the electricity grid is maintaining reliability and energy security, especially as an IEA report indicates Canada will need substantially more electricity to achieve net-zero goals, requiring careful system planning.

To address this challenge, the implementation of energy storage solutions and grid enhancements will be essential. Advances in battery technology and energy storage systems can help manage supply and demand effectively, ensuring that energy remains available even during periods of low renewable output. Additionally, integrating a diverse mix of energy sources, including hydroelectric power, can enhance the reliability of the grid.

Social Impacts

The decarbonization process also carries significant social implications. Communities that currently depend on fossil fuel industries may face economic challenges as the transition progresses, and the Canadian Gas Association has warned of potential economy-wide costs for switching to electricity, underscoring the need for a just transition.

Furthermore, there is a need for public engagement and education on the benefits and challenges of decarbonization. Canadians must understand how changes in energy policy will affect their daily lives, from electricity prices to job opportunities. Fostering a sense of community involvement can help build support for renewable energy initiatives and ensure that diverse voices are heard in the planning process.

Policy Recommendations

For Canada to successfully decarbonize its electricity grid, and building on recent electricity progress across provinces nationwide, robust and forward-thinking policies must be implemented. This includes investment in research and development to advance renewable technologies and improve energy storage solutions. Additionally, policies should encourage public-private partnerships to share the financial burden of infrastructure investments.

Governments at all levels should also promote energy efficiency measures to reduce overall demand, making the transition more manageable. Incentives for consumers to adopt renewable energy solutions, such as solar panels, can further accelerate the shift towards a decarbonized grid.

Decarbonizing Canada's electricity grid presents a complex yet necessary challenge. While there are economic, reliability, and social considerations to navigate, the potential benefits of a cleaner, more sustainable energy future are substantial. By implementing thoughtful policies and fostering community engagement, Canada can lead the way in creating an electricity grid that not only meets the needs of its citizens but also contributes to global efforts in combating climate change.

Australian Rooftop Solar Grid Constraints are driving debates over voltage rise, export limits, inverter curtailment, DER integration, and network reliability, amid concerns about localized blackouts, infrastructure protection, tariff reform, and battery storage adoption.

Key Points

Limits on solar exports to curb voltage rise, protect equipment, and keep the distribution grid reliable.

✅ Voltage rise triggers transformer protection and local outages.

✅ Export limits and smart inverter curtailment manage midday backfeed.

✅ Tariff reform and DER orchestration defer costly network upgrades.

With almost 1.8 million Australian homes and businesses relying on power from rooftop solar panels, there is a fight brewing over the impact of solar energy on the national electricity grid.

Electricity distributors are warning that as solar uptake continues to increase, there is a risk excess solar power could flow into the network, elevating power outage risks, causing blackouts and damaging infrastructure.

But is it the network businesses that are actually at risk, as customers turn away from centrally produced electricity?

This is what three different parties have to say:

Andrew Dillon of the network industry peak body, Energy Networks Australia (ENA), told 7.30 the way customers are charged for electricity has to change, or expensive grid upgrades to poles and wires will be needed to keep solar customers on the grid.

"The engineering reality is once we get too much solar in a certain space it does start to cause technical issues," he said.

"If there is too much energy coming back up the system in the middle of the day, it can cause frequency voltage disturbances in the system, which can lead to transformers tripping off to protect themselves from being damaged and that will cause localised blackouts.

"There are pockets of the grid already where we have significant penetration and we are starting to see technical issues."

However, he acknowledges that excess solar power has yet to cause any blackouts, or damage electricity infrastructure.

"I don't buy that at all," he said.

"It can be that in some suburbs or parts of suburbs a high penetration of solar on the point of use can raise voltage, these issues generally can be dealt with quickly.

"The critical issue is think where you are getting that perspective from. It is from an industry whose underlying market is threatened by customers doing it for themselves through peer-to-peer energy models. So, think with some critical insight to these claims."

He said when too many people rely on solar it threatens the very business model of the companies that own Australia's poles and wires.

"When the customers use the network less to buy centrally produced electricity, they ship less product," he said.

"When they ship less product, their underlying business is undermined, they need to charge more to the customers left and that leads to what has been called a death spiral.

"We are seeing rapid reductions in consumption at the point of use per household."

But Mr Dillon denies the distributors are acting out of self-interest.

"I absolutely reject that claim," he said.

"[What] we, as networks, have an interest in is running a safe network, running a reliable network, enabling the transition to a low carbon future and doing all that while keeping costs down as much as possible."

Solar installers say the networks are holding back business

Around Australia the poles and wires companies can decide which solar systems can connect to the grid.

Small systems can connect automatically, but in some areas, those wanting a larger system can find themselves caught up in red tape.

The vice-president of the Australian Solar Council, Glen Morris, said these limitations were holding back solar installation businesses and preventing the take-up of new battery storage technology.

"If you've already got a five kilowatt system, your house is full as far as the network is concerned," Mr Morris said.

"You go to add a battery, that's another five kilowatts and so they say no you're already full … so you can't add storage to your solar system."

The powers that be are stumbling in the dark to prevent a looming energy crisis, as the grid seeks to balance renewables' hidden challenges and competing demands.

Mr Morris also said the networks had the capacity to solve the problem of any excess solar flows into the grid, and infrastructure upgrades were not necessary.

"They already have the capability to turn off your solar invertor whenever they feel like it," he said.

"If they choose to connect that functionality, it's there in the inverter. The customer already has it."

ENA has acknowledged there is frustration with rooftop system size limits in the solar industry.

"What we are seeing is solar installers and others slightly frustrated at different requirements for different networks and sometimes they are unclear on the reasons for that," Mr Dillon said.

"Limitations are in place across the country to keep the lights on and make sure the network stays safe and we don't have sudden rushes of people connecting to the grid that causes outage issues."

But Mr Mountain is unconvinced, calling the limitations "somewhat spurious".

"The published, documented, critically reviewed analyses are few and far between, so it is very easy for engineers to make these arguments and those in policy circles only have so much tolerance for the detail," he said.

Russian cyberattacks on U.S. power grid exposed DHS warnings: Dragonfly/Energetic Bear breached control rooms, ICS networks, and could trigger blackouts via switch manipulation, phishing, and malware, threatening critical infrastructure and utility operations nationwide.

Key Points

State-backed breaches of utility ICS and control rooms enabled potential switch manipulation and blackouts.

✅ DHS: Dragonfly/Energetic Bear breached utility networks

✅ Access reached control rooms and ICS for switch control

✅ Ongoing campaign via phishing, malware, lateral movement

Russian hackers for a state-sponsored organization invaded hundreds of control rooms of U.S. electric utilities that could have led to blackouts, a new report says.

The group, known as Dragonfly or Energetic Bear, infiltrated networks of U.S. utilities as part of an effort that is likely ongoing, Department of Homeland Security officials told the Wall Street Journal.

Jonathan Home, chief of industrial-control-system analysis for DHS, said the hackers “got to the point where they could have thrown switches” and upset power flows.

Although the agency did not disclose which companies were impacted, the officials at a briefing Monday said that there were “hundreds of victims” including breaches at power plants across the U.S., and that some companies may not be aware that hackers infiltrated their networks yet.

According to experts, Russia has been preparing for such attacks for some time now, prompting a renewed focus on protecting the grid among utilities and policymakers.

“They’ve been intruding into our networks and are positioning themselves for a limited or widespread attack,” said former Deputy Assistant Defense Secretary Michael Carpenter, now senior director at the Penn Biden Center at the University of Pennsylvania, per the Wall Street Journal. “They are waging a covert war on the West.”

Earlier this year, the Trump administration claimed Russia had staged a power grid hacking campaign against the U.S. energy grid and other U.S. infrastructure.

The report comes after President Trump told reporters last week during a joint press conference in Helsinki alongside Russian President Vladimir Putin that he had no reason not to believe the Russian leader's assurances to him that the Kremlin was not to blame for interference in the election.

Trump later admitted that he misspoke when he said he didn’t “see any reason why” Russia would have meddled in the 2016 election, and said he believes the U.S. intelligence community assessment that found that the Russian government did interfere in the electoral process.
