Site C Dam Electricity Demand underscores B.C.'s decarbonization path, enabling electrification of EVs, heat pumps, and industry, aligning with BC Hydro forecasts and 2030/2050 GHG targets to supply dependable, renewable baseload power.

 

Key Points

Projected clean power tied to Site C, driven by B.C. electrification to meet 2030 and 2050 greenhouse gas targets.

✅ Aligns with 25-30% by 2030 and 55-70% by 2050 GHG cuts

✅ Supports EVs, heat pumps, and industrial electrification

✅ Provides dependable baseload alongside efficiency gains

 

There are valid reasons not to build the Site C dam. There are also valid reasons to build it. One of the latter is the rapid increase in clean electricity needed to reduce B.C.’s greenhouse gas emissions from burning natural gas, gasoline, diesel and other harmful fossil fuel products.

Although former Premier Christy Clark casually avoided near-term emissions targets, Prime Minister Justin Trudeau has set Canadian targets for both 2030 and 2050, and cleaning up Canada's electricity is critical to meeting them. Studies by my research group at Simon Fraser University and other independent analysts show that B.C.’s cost-effective contribution to these national targets requires us to reduce our emissions 25 to 30 per cent by 2030 and 55 to 70 per cent by 2050 — an energy evolution involving, among other things, a much greater use of electricity in buildings, vehicles and industry.

Recent submissions to the Site C hearing have offered widely different estimates of B.C.’s electricity demand in the decade after the project’s completion in 2025, some arguing the dam’s output will be completely surplus to domestic need for years and perhaps decades, even though improved B.C.-Alberta grid links could help balance regional demand. Some of this variation in demand forecasts is understandable. Industrial demand is especially difficult to predict, dependent as it is on global economic conditions and shifting trade relations. And there are legitimate uncertainties about B.C. Hydro’s ability to reduce electricity demand by promoting efficient products and behaviour through its Power Smart program. But some of the forecasts appear to be deliberate exaggerations, designed to support fixed positions for or against Site C.

Our university-based research team models the energy system changes required to meet national and provincial emissions targets, and we have been comparing estimates of the electricity demand implications. These estimates are produced by academics, as well as by key institutions like B.C. Hydro, the National Energy Board, and the governments of Canada and B.C.

Most electricity forecasts for B.C., including the most recent by B.C. Hydro, do not assume that B.C. reduces its greenhouse gas emissions by 25 to 30 per cent by 2030 and 55 to 70 per cent by 2050. When we adjust Hydro’s forecast for just the low end of these targets, we find that in its latest, August 30, submission to the Site C hearing, which followed the premier’s over-budget go-ahead on the project, Hydro has underestimated the demand for its electricity by about three terawatt-hours in 2025, four in 2030 and 10 in 2035. Hydro’s forecast indicates that it will need the five terawatt-hours from Site C. Our research shows that even if Hydro’s demand forecast is too high, appropriate climate policy nationally and in B.C. will absorb all the electricity the dam can produce soon after its completion.

B.C. Hydro does not forecast electricity demand to 2050. But, studies by us and others show that B.C. electricity demand will be almost double today’s levels if we are to reduce emissions by 55 to 70 per cent, even amid a documented risk of missing the 2050 target, in just over three decades while our population, economy, buildings and equipment grow significantly. Most mid- and small-sized vehicles will be electric. Most buildings will be well insulated and heated by electric resistance or electric heat-pumps, either individually or via district heating systems. And many low temperature industrial applications will be electric.

Aggressive efforts to promote energy efficiency will make an important contribution, such that energy demand will not grow nearly as fast as the economy. But it is delusional to think that humans will stop using energy. Even climate policy scenarios in which we assume unprecedented success with energy efficiency show dramatic increases in the consumption of electricity, this being the most favoured zero-emission form of energy as a replacement for planet-destroying gasoline and natural gas.

The completion of the Site C dam is a complicated and challenging societal choice, and delay-related cost risks highlighted by the premier underscore the stakes. There is unbiased evidence and argument supporting either completion or cancellation. But let’s stick to the unbiased evidence. In the case of our 2030 and 2050 greenhouse gas reduction targets, such evidence shows that we must substantially increase our generation of dependable electricity. If the Site C dam is built, and if we are true to our climate goals, all its electricity will be used in B.C. soon after completion.

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.”

Tesla’s Powerwall as the beating heart of your home

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.

Americans Keep Using Less and Less Electricity

U.S. Electricity Demand Decoupling signals GDP growth without higher load, driven by energy efficiency, LED adoption, services-led output, and rising renewables integration with the grid, plus EV charging and battery storage supporting decarbonization.

 

Key Points

GDP grows as electricity use stays flat, driven by efficiency, renewables, and a shift toward services and output.

✅ LEDs and codes cut residential and commercial load intensity.

✅ Wind, solar, and gas gain share as coal and nuclear struggle.

✅ EVs and storage can grow load and enable grid decarbonization.

 

By Justin Fox

Economic growth picked up a little in the U.S. in 2017. But electricity use fell, with electricity sales projections continuing to decline, according to data released recently by the Energy Information Administration. It's now been basically flat for more than a decade:


 

Measured on a per-capita basis, electricity use is in clear decline, and is already back to the levels of the mid-1990s.

 


 

Sources: U.S. Energy Information Administration, U.S. Bureau of Economic Analysis

*Includes small-scale solar generation from 2014 onward

 

I constructed these charts to go all the way back to 1949 in part because I can (that's how far back the EIA data series goes) but also because it makes clear what a momentous change this is. Electricity use rose and rose and rose and then ... it didn't anymore.

Slower economic growth since 2007 has been part of the reason, but the 2017 numbers make clear that higher gross domestic product no longer necessarily requires more electricity, although the Iron Law of Climate is often cited to suggest rising energy use with economic growth. I wrote a column last year about this big shift, and there's not a whole lot new to say about what's causing it: mainly increased energy efficiency (driven to a remarkable extent by the rise of LED light bulbs), and the continuing migration of economic activity away from making tangible things and toward providing services and virtual products such as games and binge-watchable TV series (that are themselves consumed on ever-more-energy-efficient electronic devices).

What's worth going over, though, is what this means for those in the business of generating electricity. The Donald Trump administration has made saving coal-fired electric plants a big priority; the struggles of nuclear power plants have sparked concern from multiple quarters. Meanwhile, U.S. natural gas production has grown by more than 40 percent since 2007, thanks to hydraulic fracturing and other new drilling techniques, while wind and solar generation keep making big gains in cost and market share. And this is all happening within the context of a no-growth electricity market.

In China, a mystery in China's electricity data has complicated global comparisons.

 

Here are the five main sources of electric power in the U.S.:


 

The big story over the past decade has been coal and natural gas trading places as the top fuel for electricity generation. Over the past year and a half coal regained some of that lost ground as natural gas prices rose from the lows of early 2016. But with overall electricity use flat and production from wind and solar on the rise, that hasn't translated into big increases in coal generation overall.

Oh, and about solar. It's only a major factor in a few states (California especially), so it doesn't make the top five. But it's definitely on the rise.

 

 

What happens next? For power generators, the best bet for breaking out of the current no-growth pattern is to electrify more of the U.S. economy, especially transportation. A big part of the attraction of electric cars and trucks for policy-makers and others is their potential to be emissions-free. But they're only really emissions-free if the electricity used to charge them is generated in an emissions-free manner -- creating a pretty strong business case for continuing "decarbonization" of the electric industry. It's conceivable that electric car batteries could even assist in that decarbonization by storing the intermittent power generated by wind and solar and delivering it back onto the grid when needed.

I don't know exactly how all this will play out. Nobody does. But the business of generating electricity isn't going back to its pre-2008 normal.

Windstorm Causes Significant Power Outages

Vancouver October 2024 Windstorm brought extreme weather to British Columbia, causing power outages, storm damage, and downed lines as BC Hydro crews led emergency response and restoration, highlighting climate change resilience and community preparedness.

 

Key Points

A severe storm with 100 km/h gusts that caused outages and damage in Vancouver, prompting wide power restoration.

✅ 100 km/h gusts toppled trees and downed power lines

✅ Over 200,000 BC Hydro customers lost electricity

✅ Crews and communities coordinated emergency response

 

In October 2024, a powerful windstorm swept through the Vancouver area, resulting in widespread power outages and disruption across the region. The storm, characterized by fierce winds and heavy rainfall, reflected conditions seen when strong winds in the Miami Valley knocked out power earlier this year, and was part of a larger weather pattern that affected much of British Columbia. Residents braced for the impacts, with local authorities and utility companies preparing for the worst.

The Storm's Impact

The windstorm hit Vancouver with wind gusts exceeding 100 km/h, toppling trees, and downing power lines. As the storm progressed, reports of damaged properties and fallen trees began to flood in. Many neighborhoods experienced significant power outages, mirroring widespread outages in Quebec earlier in the season, with thousands of residents left without electricity for extended periods. The areas hardest hit included the West End, Kitsilano, and parts of the North Shore, where the impact of the storm was particularly severe.

Utility companies, including BC Hydro operations, mobilized their crews quickly in response to the storm's aftermath. Emergency response teams worked tirelessly to restore power, often facing challenging conditions. The restoration efforts were complicated by the sheer number of outages reported—over 200,000 customers were affected at the height of the storm. Crews encountered not only downed lines but also hazardous conditions as they navigated through debris-laden streets.

Community Response and Resilience

In the wake of the storm, the community showcased remarkable resilience. Local residents rallied together to assist one another, sharing resources and providing support to those most affected. Many community centers opened their doors as emergency shelters, offering warmth and safety to those without power, a step also taken when a London power outage disrupted mornings for thousands across the city.

Authorities also emphasized the importance of preparedness in such situations. They urged residents to have emergency kits ready, including food, water, and essential supplies, noting that nearby areas like North Seattle can face sudden outages with little warning. Local officials highlighted the value of staying informed through weather updates and alerts, allowing residents to make informed decisions during extreme weather events.

The Role of Climate Change

The October windstorm serves as a stark reminder of the increasing frequency and intensity of extreme weather events, a trend often linked to climate change. Experts have noted that rising global temperatures are contributing to more severe weather patterns, including stronger storms and increased Toronto flooding events. As cities like Vancouver face the reality of climate change, discussions about infrastructure resilience and adaptation strategies have gained urgency.

City planners and environmental advocates are pushing for initiatives that enhance the city's ability to withstand extreme weather. This includes improving stormwater management systems, increasing green spaces to absorb rainfall, and investing in renewable energy sources. By addressing these challenges proactively, Vancouver aims to mitigate the impacts of future storms and protect its residents.

Moving Forward

As recovery efforts continue, the focus now shifts to restoring normalcy and preparing for future weather events. Residents are encouraged to report any ongoing outages or hazards to local authorities and to stay updated through reliable news sources. BC Hydro and other utility companies are committed to transparency, providing regular updates on power restoration efforts, even as outages can persist for days as seen in Toronto after a spring storm.

The October 2024 windstorm will be remembered not only for its immediate impacts but also as a catalyst for discussions on resilience and community preparedness. As Vancouver looks ahead, the lessons learned from this storm will shape strategies for better handling extreme weather, ensuring that the city is equipped to face the challenges posed by a changing climate.

In conclusion, while the windstorm caused significant disruption and hardship for many, it also highlighted the strength of community spirit and the importance of proactive planning in the face of climate challenges. Vancouver's response and recovery will be crucial in building a more resilient future for all its residents.

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.

Energy Efficiency and Demand Response Can Nearly Level Southeast Electricity Demand for More than a Decade

Southeast Electricity Demand Forecast examines how energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response shape grid needs, stabilize load through 2030, shift peaks, and inform utility planning across the region.

 

Key Points

An outlook of load shaped by efficiency, solar, EVs, with demand response keeping usage steady through 2030.

✅ Stabilizes regional demand through 2030 under accelerated adoption

✅ Energy efficiency and demand response are primary levers

✅ EVs and heat pumps drive growth post 2030; shift winter peaks

 

Electricity markets in the Southeast are facing many changes on the customer side of the meter. In a new report released today, we look at how energy efficiency, photovoltaics (solar electricity), electric vehicles, heat pumps, and demand response (shifting loads from periods of high demand) might affect electricity needs in the Southeast.

We find that if all of these resources are pursued on an accelerated basis, electricity demand in the region can be stabilized until about 2030.

After that, demand will likely grow in the following decade because of increased market penetration of electric vehicles and heat pumps, but energy planners will have time to deal with this growth if these projections are borne out. We also find that energy efficiency and demand response can be vital for managing electricity supply and demand in the region and that these resources can help contain energy demand growth, reducing the impact of expensive new generation on consumer wallets.

 

National trends

This is the second ACEEE report looking at regional electricity demand. In 2016, we published a study on electricity consumption in New England, finding an even more pronounced effect. For New England, with even more aggressive pursuit of energy efficiency and these other resources, consumption was projected to decline through about 2030, before rebounding in the following decade.

These regional trends fit into a broader national pattern. In the United States, electricity consumption has been characterized by flat electricity demand for the past decade. Increased energy efficiency efforts have contributed to this lack of consumption growth, even as the US economy has grown since the Great Recession. Recently, the US Energy Information Administration (EIA – a branch of the US Department of Energy) released data on US electricity consumption in 2016, finding that 2016 consumption was 0.3% below 2015 consumption, and other analysts reported a 1% slide in 2023 on milder weather.

 

Five scenarios for the Southeast

ACEEE’s new study focuses on the Southeast because it is very different from New England, with warmer weather, more economic growth, and less-aggressive energy efficiency and distributed energy policies than the Northeast. For the Southeast, we examined five scenarios: a business-as-usual scenario; two alternative scenarios with progressively higher levels of energy efficiency, photovoltaics informed by a solar strategy for the South that is emerging regionally, electric vehicles, heat pumps, and demand response; and two scenarios combining high numbers of electric vehicles and heat pumps with more modest levels of the other resources. This figure presents electricity demand for each of these scenarios:

Over the 2016-2040 period, we project that average annual growth will range from 0.1% to 1.0%, depending on the scenario, much slower than historic growth in the region. Energy efficiency is generally the biggest contributor to changes in projected 2040 electricity consumption relative to the business-as-usual scenario, as shown in the figure below, which presents our accelerated scenario that is based on levels of energy efficiency and other resources now targeted by leading states and utilities in the Southeast.

To date, Entergy Arkansas has achieved the annual efficiency savings as a percent of sales shown in the accelerated scenario and Progress Energy (a division of Duke Energy) has nearly achieved those savings in both North and South Carolina. Sixteen states outside the Southeast have also achieved these savings statewide.

The efficiency savings shown in the aggressive scenario have been proposed by the Arkansas PSC. This level of savings has already been achieved by Arizona as well as six other states. Likewise, the demand response savings we model have been achieved by more than 10 utilities, including four in the Southeast. The levels of photovoltaic, electric vehicle, and heat pump penetration are more speculative and are subject to significant uncertainty.

We also examined trends in summer and winter peak demand. Most utilities in the Southeast have historically had peak demand in the summer, often seeing heatwave-driven surges that stress operations across the Eastern U.S., but our analysis shows that winter peaks will be more likely in the region as photovoltaics and demand response reduce summer peaks and heat pumps increase winter peaks.

 

Why it’s vital to plan broadly

Our analysis illustrates the importance of incorporating energy efficiency, demand response, and photovoltaics into utility planning forecasts as utility trends to watch continue to evolve. Failing to include these resources leads to much higher forecasts, resulting in excess utility system investments, unnecessarily increasing customer electricity rates. Our analysis also illustrates the importance of including electric vehicles and heat pumps in long-term forecasts. While these technologies will have moderate impacts over the next 10 years, they could become increasingly important in the long run.

We are entering a dynamic period of substantial uncertainty for long-term electricity sales and system peaks, highlighted by COVID-19 demand shifts that upended typical patterns. We need to carefully observe and analyze developments in energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response over the next few years. As these technologies advance, we can create policies to reduce energy bills, system costs, and harmful emissions, drawing on grid reliability strategies tested in Texas, while growing the Southeast’s economy. Resource planners should be sure to incorporate these emerging trends and policies into their long-term forecasts and planning.
