California nuclear reactor shut down for blown fuse

US Electricity Demand Outlook examines EIA forecasts, GDP decoupling, energy efficiency, electrification, electric vehicles, grid load growth, and weather variability to frame long term demand trends and utility planning scenarios.

Key Points

An analysis of EIA projections showing demand decoupling from GDP, with EV adoption and efficiency shaping future grid load.

✅ EIA lowers load growth; demand decouples from GDP.

✅ Efficiency and sector shifts depress kWh sales.

✅ EV adoption could revive load and capacity needs.

Electricity producers and distributors are in an unusual business. The product they provide is available to all customers instantaneously, literally at the flip of a switch. But the large amount of equipment, both hardware and software to do this takes years to design, site and install.

From a long range planning perspective, just as important as a good engineering design is an accurate sales projections. For the US electric utility industry the most authoritative electricity demand projec-tions come from the Department of Energy’s Energy Information Administration (EIA). EIA's compre-hensive reports combine econometric analysis with judgment calls on social and economic trends like the adoption rate of new technologies that could affect future electricity demand, things like LED light-ing and battery powered cars, and the rise of renewables overtaking coal in generation.

Before the Great Recession almost a decade ago, the EIA projected annual growth in US electricity production at roughly 1.5 percent per year. After the Great Recession began, the EIA lowered its projections of US electricity consumption growth to below 1 percent. Actual growth has been closer to zero. While the EIA did not antici-pate the last recession or its aftermath, we cannot fault them on that.

After the event, though, the EIA also trimmed its estimates of economic growth. For the 2015-2030 period it now predicts 2.1 percent economic and 0.3 percent electricity growth, down from previously projections of 2.7 percent and 1.3 percent respectively. (See Figures 1 and 2.)

Table 1. EIA electric generation projections by year of forecast (kWh billions)

Table 2. EIA forecast of GDP by year of forecast (billion 2009 $)

Back in 2007, the EIA figured that every one percent increase in economic activity required a 0.48 percent in-crease in electric generation to support it. By 2017, the EIA calculated that a 1 percent growth in economic activity now only required a 0.14 percent increase in electric output. What accounts for such a downgrade or disconnect between electricity usage and economic growth? And what factors might turn the numbers 
around?

First, the US economy lost energy intensive heavy industry like smelting, steel mills and refineries; patterns in China's electricity sector highlight how industrial shifts can reshape power demand. A more service oriented economy (think health care) relies more heavily on the movement of data or information and uses far less power than a manufacturing-oriented economy.

A small volcano in Argentina is about to fuel the next tech boom – and a little known company is going to be right at the center. Early investors stand to gain incredible profits and you can too. Read the report.

Second, internet shopping has hurt so-called "brick and mortar" retailers. Despite the departure of heavy industry, in years past a burgeoning US commercial sector increased its demand and usage of electricity to offset the industrial decline. But not anymore. Energy efficiency measures as well as per-haps greater concern about global warming and greenhouse gas emissions and have cut into electricity sales. “Do more with less” has the right ring to it.

But there may be other components to the ongoing decline in electricity usage. Academic studies show that electricity usage seems to increase with income along an S curve, and flattens out after a certain income level. That is, if you earn $1 billion per year you do not (or cannot) use ten times a much electricity as someone earning only $100 million.

But people at typical, middle income levels increase or decrease electricity usage when incomes rise or fall. The squeeze on middle income families was discussed often in the late presidential campaign. In recent decades an increasing percentage of income has gone to a small percentage of the population at the top of the income scale. This trend probably accounts for some weakness in residential sales. This suggests that government policy addressing income inequality would also boost electricity sales.

Population growth affects demand for electricity as well as the economy as a whole. The EIA has made few changes in its projections, showing 0.7 percent per year population growth in 2015- 2030 in both the 2007 and 2017 forecasts. Recent studies, however, have shown a drop in the birth rate to record lows. More troubling, from a national health perspective is that the average age of death may have stopped rising. Those two factors point to lower population growth, especially if the government also restricts immi-gration. Thus, the US may be approaching a period of rather modest population growth.

All of the above factors point to minimal sales growth for electricity producers in the US--perhaps even lower than the seemingly conservative EIA estimates. But the cloud on the horizon has a silver lining in the shape of an electric car. Both the United Kingdom and France have set dates to end of production of automobiles with internal combustion engines. Several European car makers have declared that 20 percent of their output will be electric vehicles by the early 2020s. If we adopt automobiles powered by electricity and not gasoline or diesel, electricity sales would increase by one third. For the power indus-try, electric vehicles represent the next big thing.

We don’t pretend to know how electric car sales will progress. But assume vehicle turnover rates re-main at the current 7 percent per year and electric cars account for 5 percent of sales in the first five years (as op-posed to 1 percent now), 20 percent in the next five years and 50 percent in the third five year period. Wildly optimistic assumptions? Maybe. By 2030, electric cars would constitute 28 percent of the vehicle fleet. They would add about 10 percent to kilowatt hour sales by that date, assuming that battery efficiencies do not improved by then. Those added sales would require increased electric generation output, with low-emissions sources expected to cover almost all the growth globally. They would also raise long term growth rates for 2015-2030 from the present 0.3 percent to 1.0 percent. The slow upturn in demand should give the electric companies time to gear up so to speak.

In the meantime, weather will continue to play a big role in electricity consumption. Record heat-induced demand peaks are being set here in the US even as surging global demand puts power systems under strain worldwide.

Can we discern a pattern in weather conditions 15 years out? Maybe we can, but that is one topic we don’t expect a government agency to tackle in public right now. Meantime, weather will affect sales more than anything else and we cannot predict the weather. Or can we?

Belgium Energy Mix 2019 shows strong nuclear output, rising offshore wind, net electricity exports, and robust interconnections, per Elia, as the nuclear phaseout drives 3.9GW new capacity needs after improved reactor availability.

Key Points

High nuclear share, offshore wind, net exports, interconnections; 3.9GW capacity needed amid nuclear phaseout.

✅ Nuclear supplied 48.8% of generation in 2019.

✅ Net exporter: 1.8 TWh, aided by interconnections.

✅ Elia projects 3.9GW new capacity for phaseout.

Belgium's electricity transmission system operator, Elia, said that the major trends in 2019 were a steady increase in (mainly offshore) renewable power generation, illustrated by EU wind and solar records across the bloc, better availability of nuclear-generating facilities and an increase in electricity exports.

In 2019, 48.8% of the power generated in Belgium came from nuclear plants. This was in line with the total for 2017 (50%) and significantly more than in 2018 (31.2%) when several reactors were unavailable amid stunted hydro and nuclear output in Europe as well.

Belgium exported more electricity in 2019, as neighbors like Germany saw renewables overtake coal and nuclear generation, with net exports of 1.8TWh (2.1% of the energy mix), in contrast to 2018 when Belgium imported 17.5TWh (20%).

Elia said this “should be viewed in its wider context, of declining nuclear capacity in Europe and regional market shifts, against the backdrop of an increasingly Europeanised market, and can be explained primarily by the good availability of Belgium's generating facilities (especially its nuclear power stations).”

The development of interconnections was also a key factor in the circulation of these electricity flows, as seen with Irish grid price spikes highlighting regional stress, Elia noted.

“Belgium had not been a net exporter of electricity for almost 10 years, the last time being in 2009 and 2010, when total net exports represented 2.8% and 0.2% respectively of Belgium’s energy mix,” it said.

Belgian has seven nuclear reactors – three at Tihange near Liege and four at Doel near Antwerp – and, regionally, nuclear-powered France faces outage risks that influence cross-border reliability.

In 2003, Belgium decided to phase out nuclear power and passed a law to that effect, with neighbors like Germany navigating a balancing act during their energy transition, which was reaffirmed in 2015 and 2018.

A commission appointed to assess the impact of the nuclear phaseout is scheduled to be completed in 2025 but has yet to report any findings.

Elia estimates that some 3.9GW of new power generating capacity will be needed to compensate for Belgium's nuclear phaseout.

San Francisco Battery-Electric Ferries will deliver zero-emission, high-speed passenger service powered by Wartsila electric propulsion, EPMS, IAS, batteries, and shore power, advancing maritime decarbonization under the REEF program and USCG Subchapter T standards.

Key Points

They are the first US zero-emission high-speed passenger ferries using integrated electric propulsion and shore power

✅ Dual 625 kW motors enable up to 24-knot service speeds

✅ EPMS, IAS, DC hub, and shore power streamline operations

✅ Built to USCG Subchapter T for safety and compliance

Wartsila, a global leader in sustainable marine technology, has been selected to supply the electric propulsion system for the United States' first fully battery-electric, zero-emission high-speed passenger ferries. This significant development marks a pivotal step in the decarbonization of maritime transport, aligning with California's ambitious environmental goals, including recent clean-transport investments across ports and corridors.

A Leap Toward Sustainable Maritime Transport

The project, commissioned by All American Marine (AAM) on behalf of San Francisco Bay Ferry, involves the construction of three 150-passenger ferries, reflecting broader U.S. advances like the Washington State Ferries hybrid upgrade now underway. These vessels will operate on new routes connecting the rapidly developing neighborhoods of Treasure Island and Mission Bay to downtown San Francisco. The ferries are part of the Rapid Electric Emission Free (REEF) Ferry Program, a comprehensive initiative by San Francisco Bay Ferry to transition its fleet to zero-emission propulsion technology. The first vessel is expected to join the fleet in early 2027.

Wärtsilä’s Role in the Project

Wärtsilä's involvement encompasses the supply of a comprehensive electric propulsion system, including the Energy and Power Management System (EPMS), integrated automation system (IAS), batteries, DC hub, transformers, electric motors, and shore power supply. This extensive scope underscores Wärtsilä’s expertise in providing integrated solutions for emission-free marine transportation. The company's extensive global experience in developing and supplying integrated systems and solutions for zero-emission high-speed vessels, as seen with electric ships on the B.C. coast operating today, was a key consideration in the selection process.

Technical Specifications of the Ferries

The ferries will be 100 feet (approximately 30 meters) in length, with a beam of 26 feet and a draft of 5.9 feet. Each vessel will be powered by dual 625-kilowatt electric motors, enabling them to achieve speeds of up to 24 knots. The vessels will be built to U.S. Coast Guard Subchapter T standards, ensuring compliance with stringent safety regulations.

Environmental and Operational Benefits

The transition to battery-electric propulsion offers numerous environmental and operational advantages. Electric ferries produce zero emissions during operation, as demonstrated by Berlin's electric ferry deployments, significantly reducing the carbon footprint of maritime transport. Additionally, electric propulsion systems are generally more efficient and require less maintenance compared to traditional diesel engines, leading to lower operational costs over the vessel's lifespan.

Broader Implications for Maritime Decarbonization

This project is part of a broader movement toward sustainable maritime transport in the United States. San Francisco Bay Ferry has also approved the purchase of two larger 400-passenger battery-electric ferries for transbay routes, further expanding its commitment to zero-emission operations. The agency has secured approximately $200 million in funding from local, state, and federal sources, echoing infrastructure bank support seen in B.C., to support these initiatives, including vessel construction and terminal electrification.

Wartsila’s involvement in this project highlights the company's leadership in the maritime industry's transition to sustainable energy solutions, including hybrid-electric pathways like BC Ferries' new hybrids now in service. With a proven track record in supplying integrated systems for zero-emission vessels, Wärtsilä is well-positioned to support the global shift toward decarbonized maritime transport.

As the first fully battery-electric high-speed passenger ferries in the United States, these vessels represent a significant milestone in the journey toward sustainable and environmentally responsible maritime transportation, paralleling regional advances such as the Kootenay Lake electric-ready ferry entering service. The collaboration between Wärtsilä, All American Marine, and San Francisco Bay Ferry exemplifies the collective effort required to realize a zero-emission future for the maritime industry.

The deployment of these battery-electric ferries in San Francisco Bay not only advances the city's environmental objectives but also sets a precedent for other regions to follow. With continued innovation and collaboration, the maritime industry can look forward to a future where sustainable practices are the standard, not the exception.

Ontario-Quebec Electricity Trade Agreement ends as Ontario pivots to IESO procurement, hydropower alternatives, natural gas capacity, and energy auctions, impacting grid reliability, power imports, and GHG emissions across both provincial markets.

Key Points

A seven-year power import pact; Ontario will end it, shifting to IESO procurement and gas capacity.

✅ Seasonal hydropower exchange of 2.3 TWh annually.

✅ IESO projects Quebec supply constraints by decade end.

✅ Ontario adds gas, auctions; near-term sector GHGs rise.

The Ontario government does not plan to renew the Ontario-Quebec electricity trade agreement, Radio-Canada is reporting.

The seven-year contract, which expires next year, aims to reduce Ontario's greenhouse gas (GHG) emissions by buying 2.3 Terawatt-hours of electricity from Quebec annually — that corresponds to about seven per cent of Hydro-Quebec's average annual exports.

The announcement comes as the provincially owned Quebec utility continues its legal battle over a plan to export power to Massachusetts.

The Ontario agreement has guaranteed a seasonal exchange of energy, since Quebec has a power surplus in summer, and the province's electricity needs increase in the winter. Ontario plans on exercising its last and only option in the summer of 2026, for a block of 500 megawatts.

The office of the Ontario Minister of Energy Todd Smith says the province will save money by relying "on a competitive procurement process" instead, amid debates over clean, affordable electricity policy in Ontario. And, the Independent Electricity System Operator (IESO), the equivalent of Hydro-Quebec in Ontario, added that, at any rate, Quebec is expected to "run out of electricity in the middle or at the end of the decade."

During the Quebec election campaign, Premier Francois Legault said his province needed to increase hydroelectricity production because he is expecting demand for hydroelectricity to increase by an additional 100 terawatt-hours in the coming decades — half of Hydro-Quebec's current annual output.

Coalition Avenir Quebec pitches more hydro dams to Quebec voters
The provinces will still continue to buy and sell power, reaching deals through annual energy auctions.

Eloise Edom, an associate researcher at Polytechnique Montreal's Institut de l'energie Trottier, says the announcement came as somewhat of a surprise because "we're still talking about a lot of energy."

Hydro-Quebec refused to comment on "the SIERE [Independent Electricity System Operator]'s intentions for the agreement, which ends next year," said company spokesperson Lynn St-Laurent.

No green options
Yet Ontario is running out of electricity, even as questions persist about whether it is embracing clean power to meet demand, in part because of plans to refurbish nuclear reactors at the Bruce and Darlington generator stations.

Windsor has already lost out on a $2.5-billion factory because the region is short of electricity for new industrial loads. And by 2025, Toronto will run out of power for the electrification of its transit system, according to the latest estimates from the IESO.

The Ford government recently announced that it hopes to extend the life of the Pickering nuclear station amid ongoing debate. It is also evaluating the possibility of increasing hydroelectricity production at its existing dams.

For now, Ontario is banking on its natural gas plants to meet demand, which have won most recent IESO tenders for contracts running until 2026. Last Friday, the province announced that it was going to buy an additional 1,500 megawatts by 2027.

"The [Ontario energy] minister's expectations may be that the increase in natural gas prices is temporary and that it will fade," energy economist Jean-Thomas Bernard said. "With this in mind, he probably does not want to sign a long-term contract [with Hydro-Quebec] and prefers to buy electricity on a day-to-day basis and through calls for tenders."

If the Quebec deal expires, Ontario, Canada's second highest GHG emitter, would have to increase its emissions for the sector, at least in the medium term, with electricity getting dirtier as gas fills the gap.

Last year, the IESO found that it would be very difficult to set a moratorium on natural gas before 2030. The IESO must produce a final report on the subject for the energy minister by the end of November.

Massachusetts Energy Code Updates align DOER regulations with BBRS standards, advancing Stretch Code and Specialized Code beyond the Base Energy Code to accelerate net-zero construction, electrification, and high-efficiency building performance across municipal opt-in communities.

Key Points

They are DOER-led changes to Base, Stretch, and Specialized Codes to drive net-zero, electrified, efficient buildings.

✅ Updates apply Base, Stretch, or opt-in Specialized Code.

✅ Targets net-zero by 2050 with electrification-first design.

✅ Municipalities choose code path via City Council or Town Meeting.

Massachusetts will soon see significant updates to the energy codes that govern the construction and alteration of buildings throughout the Commonwealth.

As required by the 2021 climate bill, the Massachusetts Department of Energy Resources (DOER) has recently finalized regulations updating the current Stretch Energy Code, previously promulgated by the state's Board of Building Regulations and Standards (BBRS), and establishing a new Specialized Code geared toward achieving net-zero building energy performance.

The final code has been submitted to the Joint Committee on Telecommunications, Utilities, and Energy for review as required under state law, amid ongoing Connecticut market overhaul discussions that could influence regional dynamics.

Under the new regulations, each municipality must apply one of the following:

Base Energy Code - The current Base Energy Code is being updated by the BBRS as part of its routine updates to the full set of building codes. This base code is the default if a municipality has not opted in to an alternative energy code.

Stretch Code - The updated Stretch Code creates stricter guidelines on energy-efficiency for almost all new constructions and alterations in municipalities that have adopted the previous Stretch Code, paralleling 100% carbon-free target in Minnesota and elsewhere to support building decarbonization. The updated Stretch Code will automatically become the applicable code in any municipality that previously opted-in to the Stretch Code.

Specialized Code - The newly created Specialized Code includes additional requirements above and beyond the Stretch Code, designed to get to ensure that new construction is consistent with a net-zero economy by 2050, similar to Canada's clean electricity regulations that set a 2050 decarbonization pathway. Municipalities must opt-in to adopt the Specialized Code by vote of City Council or Town Meeting.

The new codes are much too detailed to summarize in a blog post. You can read more here. Without going into those details here, it is worth noting a few significant policy implications of the new regulations:

With roughly 90% of Massachusetts municipalities having already adopted the prior version of the Stretch Code, the Commonwealth will effectively soon have a new base code that, even if it does not mandate zero-energy buildings, is nonetheless very aggressive in pushing new construction to be as energy-efficient as possible, as jurisdictions such as Ontario clean electricity regulations continue to reshape the power mix.

Although some concerns have been raised about the cost of compliance, particularly in a period of high inflation, and amid solar demand charge debates in Massachusetts, our understanding is that many developers have indicated that they can work with the new regulations without significant adverse impacts.

Of course, the success of the new codes depends on the success of the Commonwealth's efforts to transition quickly to a zero-carbon electrical grid, supported by initiatives like the state's energy storage solicitation to bolster reliability. If the cost of doing so is higher than expected, there could well be public resistance. If new transmission doesn't get built out sufficiently quickly or other problems occur, such that the power is not available to electrify all new construction, that would be a much more significant problem - for many reasons!

In short, the new regulations unquestionably set the Commonwealth on a course to electrify new construction and squeeze carbon emissions out of new buildings. However, as with the rest of our climate goals, there are a lot of moving pieces, including proposals for a clean electricity standard shaping the power sector that are going to have to come together to make the zero-carbon economy a reality.

Texas After-Labor Day School Start could ease ERCOT's power grid strain by shifting peak demand, lowering air-conditioning loads in schools, improving grid reliability, reducing electricity costs, and curbing emissions during extreme heat the summer months.

Key Points

A proposed calendar shift to start school after Labor Day to lower ERCOT peak demand, costs, and grid risk.

✅ Cuts school HVAC loads during peak summer heat

✅ Lowers costly peaker plant use and electricity rates

✅ Requires calendar changes, testing and activities shifts

As Texas faces increasing demands on its power grid, a new proposal is gaining traction: starting the school year after Labor Day. This idea, reported by the Dallas News, suggests that delaying the start of the academic year could help alleviate some of the pressure on the state’s electricity grid during the peak summer months, potentially leading to both grid stability and financial savings. Here’s an in-depth look at how this proposed change could impact Texas’s energy landscape and education system.

The Context of Power Grid Strain

Texas's power grid, operated by the Electric Reliability Council of Texas (ERCOT), has faced significant challenges in recent years. Extreme weather events, record-breaking temperatures, and high energy demand have strained the grid, and some analyses argue that climate change, not demand is the biggest challenge today, leading to concerns about reliability and stability. The summer months are particularly taxing, as the demand for air conditioning surges, often pushing the grid to its limits.

In this context, the idea of adjusting the school calendar to start after Labor Day has been proposed as a potential strategy to help manage electricity demand. By delaying the start of school, proponents argue that it could reduce the load on the power grid during peak usage periods, thereby easing some of the stress on energy resources.

Potential Benefits for the Power Grid

The concept of delaying the school year is rooted in the potential benefits for the power grid. During the hottest months of summer, the demand for electricity often spikes as families use air conditioning to stay cool, and utilities warn to prepare for blackouts as summer takes hold. School buildings, typically large and energy-intensive facilities, contribute significantly to this demand when they are in operation.

Starting school later could help reduce this peak demand, as schools would be closed during the hottest months when the grid is under the most pressure. This reduction in demand could help prevent grid overloads and reduce the risk of power outages, at a time when longer, more frequent outages are afflicting the U.S. power grid, ultimately contributing to a more stable and reliable electricity supply.

Additionally, a decrease in peak demand could help lower electricity costs. Power plants, particularly those that are less efficient and more expensive to operate, are often brought online during periods of high demand. By reducing the peak load, the state could potentially minimize the need for these costly power sources, leading to lower overall energy costs.

Financial and Environmental Considerations

The financial implications of starting school after Labor Day extend beyond just the power grid. By reducing energy consumption during peak periods, the state could see significant savings on electricity costs. This, in turn, could lead to lower utility bills for schools, businesses, and residents alike, a meaningful relief as millions risk electricity shut-offs during summer heat.

Moreover, reducing the demand for electricity from fossil fuel sources can have positive environmental impacts. Lower peak demand may reduce the reliance on less environmentally friendly energy sources, and aligns with calls to invest in a smarter electricity infrastructure nationwide, thereby decreasing greenhouse gas emissions and contributing to overall environmental sustainability.

Challenges and Trade-offs

While the proposal offers potential benefits, it also comes with challenges and trade-offs. Adjusting the school calendar would require significant changes to the academic schedule, potentially affecting extracurricular activities, summer programs, and family plans, and comparisons to California's reliability challenges underscore the complexity. Additionally, there could be resistance from various stakeholders, including parents, educators, and students, who are accustomed to the current school calendar.

There are also logistical considerations to address, such as how a delayed start might impact standardized testing schedules and the academic calendar for higher education institutions. These factors would need to be carefully evaluated to ensure that the proposed changes do not adversely affect educational outcomes or create unintended consequences.

Looking Ahead

The idea of starting Texas schools after Labor Day represents an innovative approach to addressing the challenges facing the state’s power grid. By potentially reducing peak demand and lowering energy costs, and alongside efforts to connect Texas's grid to the rest of the nation, this proposal could contribute to greater grid stability and financial savings. However, careful consideration and planning will be essential to navigate the complexities of altering the school calendar and to ensure that the benefits outweigh the challenges.

As Texas continues to explore solutions for managing its power grid and energy resources, the proposal to shift the school year schedule provides an intriguing possibility. It reflects a broader trend of seeking creative and multifaceted approaches to balancing energy demand, environmental sustainability, and public needs.

In conclusion, starting schools after Labor Day could offer tangible benefits for Texas’s power grid and financial well-being. As discussions on this proposal advance, it will be important to weigh all factors and engage stakeholders to ensure a successful and equitable implementation.
