Several Milestones Reached at Nuclear Power Projects Around the World

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.

CAISO Net Negative Emissions signal moments when greenhouse gas intensity of serving ISO demand drops below zero, driven by high renewable generation, low load, strong solar exports, and imports accounting in the California grid.

Key Points

Moments when CAISO's CO2 to serve demand is below zero, driven by renewables, exports, and import accounting.

✅ Calculated using imports and exports to serve ISO demand

✅ Occur during high solar output, low weekend load

✅ Coincide with curtailment and record renewable penetration

We’re a long way from the land of milk and honey, but on Easter Sunday – for about an hour – we got a taste.

On Sunday, at 1:55 PM Pacific Time the California Independent Systems Operator (CAISO) reported that greenhouse gas emissions necessary to serve its demand (~80% of California’s electricity demand on an annual basis), was measured at a rate -16 metric tons of CO2 per hour. Five minutes later, the value was -2 mTCO2/h, before it crept back up to 40 mTCO2/h at 2:05 PM PST. At 2:10 PST though it fell back to -86 mTCO2/h and stayed negative until 3:05 PM PST, even as global CO2 emissions flatlined in 2019 according to the IEA.

This information was brought to the attention of pv magazine via tweet from eagle eye Jon Pa after CAISO’s site first noted the negative values:

The region was still generating CO2 though, as natural gas, biogas, biomass, geothermal and even coal plants were running and pumping out emissions, even as potent greenhouse gases declined in the US under control efforts. CAISO’s Greenhouse Gas Emission Tracking Methodology, December 28, 2016 (pdf) notes the below calculations to create the value what it terms, “Total GHG emissions to serve ISO demand”:

Of importance to note is that to get to the net negative value, CAISO considered all electricity imports and exports, a reminder that climate policy shapes grid operations across North America. And as can be noted in the image below the CO2 intensity of imports during the day rapidly declined as the sun came up, first going negative around 9:05 AM PST, and mostly staying so until just before 6 PM PST.

During this same weekend, other records were noted (reiterating that we’re in record setting season and as the state pursues its 100% carbon-free mandate now in law) such as a new electricity export record of greater than 2 GW and total renewable electricity as part of total demand at greater than 70%.

At the peak negative moment of 2:15 PM PST, -112 mTCO2/h seen below, the total amount of clean instantaneous generation being used in the power grid region was 17 GW, a far cry from heat-driven reliability strains like rolling blackout warnings that arise during extreme demand, with renewables giving 76% of the total, hydro 14%, nuclear 13% and imports of -12% countering the CO2 coming from just over 1.4 GW of gas generation.

Also of importance are a few layers of nuance in the electricity demand charts. First off we’re in the shoulder seasons  of California – nice cool weather before the warmth of summer drives air conditioning demand. Additional the weekend electricity demand is always lower, as well, Easter Sunday might have had an affect, whereas in colder regions Calgary’s electricity use can soar during frigid snaps.

Lastly to note was the amount of electricity from solar and wind generation being curtailed. And while the Sunday numbers weren’t available yet, the below image noted Saturday with 10 GWh in total being curtailed (pdf) – peaking at over 3.2 GW of instantaneous mostly solar power even as solar is now the cheapest electricity according to the IEA, in the hours of 2 and 3 PM PST. On an annualized basis, less than 2% of total potential solar electricity was curtailed in 2018.

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.

Russia Bitcoin Mining Ban highlights electricity deficits, grid stability concerns, and sustainability challenges, prompting stricter cryptocurrency regulation as mining operations in Siberia face shutdowns, relocations, and renewed focus on energy efficiency and resource allocation.

Key Points

Policy halting Bitcoin mining in key regions to ease electricity deficits, stabilize the grid, and prioritize energy.

✅ Targets high-load regions like Siberia facing electricity deficits

✅ Protects residential and industrial energy security, limits outages

✅ Prompts miner relocations, regulation, and potential renewables

In a significant shift in its stance on cryptocurrency, Russia has announced plans to ban Bitcoin mining in several key regions, primarily due to rising electricity deficits. This move highlights the ongoing tensions between energy management and the growing demand for cryptocurrency mining, which has sparked a robust debate about sustainability and resource allocation in the country.

Background on Bitcoin Mining in Russia

Russia has long been a major player in the global cryptocurrency landscape, particularly in Bitcoin mining. The country’s vast and diverse geography offers ample opportunities for mining, with several regions boasting low electricity costs and cooler climates that are conducive to operating the high-powered computers used for mining, similar to Iceland's mining boom in cold regions.

However, the boom in mining activities has put a strain on local electricity grids, as seen with BC Hydro suspensions in Canada, particularly as demand for energy continues to rise. This situation has become increasingly untenable, leading government officials to reconsider the viability of allowing large-scale mining operations.

Reasons for the Ban

The decision to ban Bitcoin mining in certain regions stems from a growing electricity deficit that has been exacerbated by both rising temperatures and increased energy consumption. Reports indicate that some regions are struggling to meet domestic energy needs, and jurisdictions like Manitoba's pause on crypto connections reflect similar grid concerns, particularly during peak consumption periods. Officials have expressed concern that continuing to support cryptocurrency mining could lead to blackouts and further strain on the electrical infrastructure.

Additionally, this ban is seen as a measure to redirect energy resources toward more critical sectors, including residential heating and industrial needs. By curbing Bitcoin mining, the government aims to prioritize the energy security of its citizens and maintain stability within its energy markets and the wider global electricity market dynamics.

Regional Impact

The regions targeted by the ban include areas that have seen a significant influx of mining operations, often attracted by the low costs of electricity. For instance, Siberia, known for its abundant natural resources and inexpensive power, has become a major center for miners. The ban is likely to have profound implications for local economies that have come to rely on the influx of investments from cryptocurrency companies.

Many miners are expected to be affected financially as they may have to halt operations or relocate to regions with more favorable regulations. This could lead to job losses and a decline in local business activities that have sprung up around the mining industry, such as hardware suppliers and tech services.

Broader Implications for Cryptocurrency in Russia

This ban reflects a broader trend within Russia’s approach to cryptocurrencies. While the government has been cautious about outright banning digital currencies, it has simultaneously sought to regulate the industry more stringently. Recent legislation has aimed to establish a legal framework for cryptocurrencies, focusing on taxation and oversight while navigating the balance between innovation and regulation.

As other countries around the world grapple with the implications of cryptocurrency mining, Russia’s decision adds to the narrative of the challenges associated with energy consumption in this sector. The international community is increasingly aware of the environmental impact of Bitcoin mining, which has come under fire for its significant energy use and carbon footprint.

Future of Mining in Russia

Looking ahead, the future of Bitcoin mining in Russia remains uncertain. While some regions may implement strict bans, others could potentially embrace a more regulated approach to mining, provided it aligns with energy availability and environmental considerations. The country’s vast landscape offers opportunities for innovative solutions, such as utilizing renewable energy sources, even as India's solar growth slows amid rising coal generation, to power mining operations.

As global attitudes toward cryptocurrency evolve, Russia will likely continue to adapt its policies in response to both domestic energy needs and international pressures, including Europe's shift away from Russian energy that influence policy choices. The balance between fostering a competitive cryptocurrency market and ensuring energy sustainability will be a key challenge for Russian policymakers moving forward.

Russia’s decision to ban Bitcoin mining in key regions marks a pivotal moment in the intersection of cryptocurrency and energy management. As the nation navigates its energy deficits, the implications for the mining industry and the broader cryptocurrency landscape will be significant. This move not only underscores the need for responsible energy consumption in the digital age but also reflects the complexities of integrating emerging technologies within existing frameworks of governance and infrastructure. As the situation unfolds, all eyes will be on how Russia balances innovation with sustainability in its approach to cryptocurrency.

US Electricity Demand Stagnation reflects decoupling from GDP as TVA's IRP revises outlook, with energy efficiency, distributed generation, renewables, and cheap natural gas undercutting coal, reshaping utility business models and accelerating grid modernization.

Key Points

US electricity demand stagnation is flat load growth driven by efficiency, DG, and decoupling from GDP.

✅ Flat sales pressure IOU profits and legacy baseload investments.

✅ Efficiency and rooftop solar reduce load growth and capacity needs.

✅ Utilities must pivot to services, DER orchestration, and grid software.

The US electricity sector is in a period of unprecedented change and turmoil, with emerging utility trends reshaping strategies across the industry today. Renewable energy prices are falling like crazy. Natural gas production continues its extraordinary surge. Coal, the golden child of the current administration, is headed down the tubes.

In all that bedlam, it’s easy to lose sight of an equally important (if less sexy) trend: Demand for electricity is stagnant.

Thanks to a combination of greater energy efficiency, outsourcing of heavy industry, and customers generating their own power on site, demand for utility power has been flat for 10 years, with COVID-19 electricity demand underscoring recent variability and long-run stagnation, and most forecasts expect it to stay that way. The die was cast around 1998, when GDP growth and electricity demand growth became “decoupled”:

This historic shift has wreaked havoc in the utility industry in ways large and small, visible and obscure. Some of that havoc is high-profile and headline-making, as in the recent requests from utilities (and attempts by the Trump administration) to bail out large coal and nuclear plants amid coal and nuclear industry disruptions affecting power markets and reliability.

Some of it, however, is unfolding in more obscure quarters. A great example recently popped up in Tennessee, where one utility is finding its 20-year forecasts rendered archaic almost as soon as they are released.

Falling demand has TVA moving up its planning process

Every five years, the Tennessee Valley Authority (TVA) — the federally owned regional planning agency that, among other things, supplies electricity to Tennessee and parts of surrounding states — develops an Integrated Resource Plan (IRP) meant to assess what it requires to meet customer needs for the next 20 years.

The last IRP, completed in 2015, anticipated that there would be no need for major new investment in baseload (coal, nuclear, and hydro) power plants; it foresaw that energy efficiency and distributed (customer-owned) energy generation would hold down demand.

Even so, TVA underestimated. Just three years later, the Times Free Press reports, “TVA now expects to sell 13 percent less power in 2027 than it did two decades earlier — the first sustained reversal in the growth of electricity usage in the 85-year history of TVA.”

TVA will sell less electricity in 10 years than it did 10 years ago. That is bonkers.

This startling shift in prospects has prompted the company to accelerate its schedule. It will now develop its next IRP a year early, in 2019.

Think for a moment about why a big utility like TVA (serving 9 million customers in seven states, with more than $11 billion in revenue) sets out to plan 20 years ahead. It is investing in extremely large and capital-intensive infrastructure like power plants and transmission lines, which cost billions of dollars and last for decades. These are not decisions to make lightly; the utility wants to be sure that they will still be needed, and will still pay off, for many years to come.

Now think for a moment about what it means for the electricity sector to be changing so fast that TVA’s projections are out of date three years after its last IRP, so much so that it needs to plunge back into the multimillion-dollar, year-long process of developing a new plan.

TVA wanted a plan for 20 years; the plan lasted three.

The utility business model is headed for a reckoning

TVA, as a government-owned, fully regulated utility, has only the goals of “low cost, informed risk, environmental responsibility, reliability, diversity of power and flexibility to meet changing market conditions,” as its planning manager told the Times Free Press. (Yes, that’s already a lot of goals!)

But investor-owned utilities (IOUs), which administer electricity for well over half of Americans, face another imperative: to make money for investors. They can’t make money selling electricity; monopoly regulations forbid it, raising questions about utility revenue models as marginal energy costs fall. Instead, they make money by earning a rate of return on investments in electrical power plants and infrastructure.

The problem is, with demand stagnant, there’s not much need for new hardware. And a drop in investment means a drop in profit. Unable to continue the steady growth that their investors have always counted on, IOUs are treading water, watching as revenues dry up

Utilities have been frantically adjusting to this new normal. The generation utilities that sell into wholesale electricity markets (also under pressure from falling power prices; thanks to natural gas and renewables, wholesale power prices are down 70 percent from 2007) have reacted by cutting costs and merging. The regulated utilities that administer local distribution grids have responded by increasing investments in those grids, including efforts to improve electricity reliability and resilience at lower cost.

But these are temporary, limited responses, not enough to stay in business in the face of long-term decline in demand. Ultimately, deeper reforms will be necessary.

As I have explained at length, the US utility sector was built around the presumption of perpetual growth. Utilities were envisioned as entities that would build the electricity infrastructure to safely and affordably meet ever-rising demand, which was seen as a fixed, external factor, outside utility control.

But demand is no longer rising. What the US needs now are utilities that can manage and accelerate that decline in demand, increasing efficiency as they shift to cleaner generation. The new electricity paradigm is to match flexible, diverse, low-carbon supply with (increasingly controllable) demand, through sophisticated real-time sensing and software.

That’s simply a different model than current utilities are designed for. To adapt, the utility business model must change. Utilities need newly defined responsibilities and new ways to make money, through services rather than new hardware. That kind of reform will require regulators, politicians, and risky experiments. Very few states — New York, California, Massachusetts, a few others — have consciously set off down that path.

Flat or declining demand is going to force the issue

Even if natural gas and renewables weren’t roiling the sector, the end of demand growth would eventually force utility reform.

To be clear: For both economic and environmental reasons, it is good that US power demand has decoupled from GDP growth. As long as we’re getting the energy services we need, we want overall demand to decline. It saves money, reduces pollution, and avoids the need for expensive infrastructure.

But the way we’ve set up utilities, they must fight that trend. Every time they are forced to invest in energy efficiency or make some allowance for distributed generation (and they must always be forced), demand for their product declines, and with it their justification to make new investments.

Only when the utility model fundamentally changes — when utilities begin to see themselves primarily as architects and managers of high-efficiency, low-emissions, multidirectional electricity systems rather than just investors in infrastructure growth — can utilities turn in earnest to the kind planning they need to be doing.

In a climate-aligned world, utilities would view the decoupling of power demand from GDP growth as cause for celebration, a sign of success. They would throw themselves into accelerating the trend.

Instead, utilities find themselves constantly surprised, caught flat-footed again and again by a trend they desperately want to believe is temporary. Unless we can collectively reorient utilities to pursue rather than fear current trends in electricity, they are headed for a grim reckoning.

GMP Tesla Powerwall Program replaces utility meters with smart battery storage, enabling virtual power plant services, demand response, and resilient homes, integrating solar readiness, EV charging support, and smart grid controls across Vermont households.

Key Points

Green Mountain Power uses Tesla Powerwalls as smart meters, creating a VPP for demand response and home backup.

✅ $30 monthly for 10 years or $3,000 upfront for two units

✅ Utility controls batteries for peak shaving and demand response

✅ Enables backup power, solar readiness, and EV charging support

There are more than 100 million single-family homes in the United States of America. If each of these homes were to have two 13.5 kWh Tesla Powerwalls, that would total 2.7 Terawatt-hours worth of electricity stored. Prior research has suggested that this volume of energy storage could get us halfway to the 5.4 TWh of storage needed to let the nation get 80% of its electricity from solar and wind, as states like California increasingly turn to grid batteries to support the transition.

Vermont utility Green Mountain Power (GMP) seeks to remove standard electric utility metering hardware and replace it with the equipment inside of a Tesla Powerwall, as part of a broader digital grid evolution underway. Mary Powell, President and CEO of Green Mountain Power, says, “We have a vision of a battery system in every single home” and they’ve got a patent pending software solution to make it happen.

The Resilient Home program will install two standard Tesla Powerwalls each in 250 homes in GMP’s service area. The homeowner will pay either $30 a month for ten years ($3,600), or $3,000 up front. At the end of the ten year period, payments end, but the unit can stay in the home for an additional five years – or as long as it has a usable life.

A single Powerwall costs approximately $6,800, making this a major discount.

GMP notes that the home must have reliable internet access to allow GMP and Tesla to communicate with the Powerwall. GMP will control the functions of the Powerwall, effectively operating a virtual power plant across participating homes, expanding the scope of programs like those that saved the state’s ratepayers more than $500,000 during peak demand events last year. The utility specifically notes that customers agree to share stored energy with GMP on several peak demand days each year.

The hardware can be designed to interact with current backup generators during power outages, or emerging fuel cell solutions that maintain battery charge longer during extended outages, however, the units will not charge from the generator. As noted the utility will be making use of the hardware during normal operating times, however, during a power outage the private home owner will be able to use the electricity to back up both their house and top off their car.

The utility told pv magazine USA that the Powerwalls are standard from the factory, with GMP’s patent pending software solution being the special sauce (has a hint of recent UL certifications). GMP said the program will also get home owners “adoption ready” for solar power, including microgrid energy storage markets, and other smart devices.

Sonnen’s ecoLinx is already directly interacting with a home’s electrical panel (literally throwing wifi enabled circuit breakers). Now with Tesla Powerwalls being used to replace utility meters, we see one further layer of integration that will lead to design changes that will drive residential solar toward $1/W. Electric utilities are also experimenting with controlling module level electronics and smart solar inverters in 100% residential penetration situations. And of course, considering that California is requiring solar – and probably storage in the future – in all new homes, we should expect to see further experimentation in this model. Off grid solar inverter manufacturers already include electric panels with their offerings.

If we add in the electric car, and have vehicle-to-grid abilities, we start to see a very strong amount of electricity generation and energy storage, helping to keep the lights on during grid stress, potentially happening in more than 100 million residential power plants. Resilient homes indeed.
