Solar plane completes 24-hour flight

Pacific Northwest Transmission Bottleneck slows clean energy progress as BPA's aging grid constrains renewable interconnections, delaying wind, solar, and data center growth; decarbonization targets depend on transmission upgrades, new substations, and policy reform.

Key Points

An interconnection and capacity shortfall on BPA's aging grid that delays renewables and impedes clean energy goals.

✅ BPA approvals lag: 1 of 469 projects since 2015.

✅ Yakama solar waits for substation upgrades until 2027.

✅ Data centers and decarbonization targets face grid constraints.

Oregon and Washington have set ambitious targets to decarbonize their power sectors, aiming for 100% clean electricity in the coming decades. However, a significant obstacle stands in the way: the region's aging and overburdened transmission grid, underscoring why 100% renewables remain elusive even as momentum builds.

The Grid Bottleneck

The BPA operates a transmission system that is nearly a century old in some areas, and its capacity has not expanded sufficiently to accommodate the influx of renewable energy projects, reflecting stalled grid spending in many parts of the U.S., according to recent analyses. Since 2015, 469 large renewable projects have applied to connect to the BPA's grid; however, only one has been approved—a stark contrast to other regions in the country. This bottleneck has left numerous wind and solar projects in limbo, unable to deliver power to the grid.

One notable example is the Yakama Nation's solar project. Despite receiving a $32 million federal grant under the bipartisan infrastructure law as part of a broader grid overhaul for renewables, the tribe faces significant delays. The BPA estimates that it will take until 2027 to complete the necessary upgrades to the transmission system, including a new substation, before the solar array can be connected. This timeline poses a risk of losing federal funding if the project isn't operational by 2031.

Economic and Environmental Implications

The slow pace of grid expansion has broader implications for the region's economy and environmental goals. Data centers and other energy-intensive industries are increasingly drawn to the Pacific Northwest due to its clean energy potential, while interregional projects like the Wyoming-to-California wind link illustrate how transmission access can unlock supply. However, without adequate infrastructure, these industries may seek alternatives elsewhere. Additionally, the inability to integrate renewable energy efficiently hampers efforts to reduce greenhouse gas emissions and combat climate change.

Policy Challenges and Legislative Efforts

Efforts to address the grid limitations through state-level initiatives have faced challenges, even as a federal rule to boost transmission advances nationally. In 2025, both Oregon and Washington considered legislation to establish state bonding authorities aimed at financing transmission upgrades. However, these bills failed to pass, leaving the BPA as the primary entity responsible for grid expansion. The BPA's unique structure—operating as a self-funded federal agency without direct state oversight—has made it difficult for regional leaders to influence its decision-making processes.

Looking Ahead

The Pacific Northwest's renewable energy aspirations hinge on modernizing its transmission infrastructure, aligning with decarbonization strategies that emphasize grid buildout. While the BPA has proposed several projects to enhance grid capacity, the timeline for completion remains uncertain. Without significant investment and policy reforms, the region risks falling behind in the transition to a clean energy future. Stakeholders across Oregon and Washington must collaborate to advocate for necessary changes and ensure that the grid can support the growing demand for renewable energy.

The Pacific Northwest's commitment to clean energy is commendable, but achieving these goals requires overcoming substantial infrastructure challenges, and neighboring jurisdictions such as British Columbia have pursued B.C. regulatory streamlining to accelerate projects. Addressing the limitations of the BPA's transmission system is critical to unlocking the full potential of renewable energy in the region. Only through concerted efforts at the federal, state, and local levels can Oregon and Washington hope to realize their green energy ambitions.

Great Britain electricity generation spans renewables and baseload: wind, solar, nuclear, gas, and biomass, supported by National Grid interconnectors, embedded energy estimates, and BMRS data for dynamic imports and exports across Europe.

Key Points

A diverse, weather-driven mix of renewables, gas, nuclear, and imports coordinated by National Grid.

✅ Baseload from nuclear and biomass; intermittent wind and solar

✅ Interconnectors trade zero carbon imports via subsea cables

✅ Data from BMRS and ESO covers embedded energy estimates

Great Britain has one of the most diverse ranges of electricity generation in Europe, with everything from windfarms off the coast of Scotland to a nuclear power station in Suffolk tasked with keeping the lights on. The increasing reliance on renewable energy sources, as part of the country’s green ambitions, also means there can be rapid shifts in the main source of electricity generation. On windy days, most electricity generation comes from record wind generation across onshore and offshore windfarms. When conditions are cold and still, gas-fired power stations known as peaking plants are called into action.

The electricity system in Great Britain relies on a combination of “baseload” power – from stable generators such as nuclear and biomass plants – and “intermittent” sources, such as wind and solar farms that need the right weather conditions to feed energy into the grid. National Grid also imports energy from overseas, through subsea cables known as interconnectors that link to France, Belgium, Norway and the Netherlands. They allow companies to trade excess power, such as renewable energy created by the sun, wind and water, between different countries. By 2030 it is hoped that 90% of the energy imported by interconnectors will be from zero carbon energy sources, though low-carbon electricity generation stalled in 2019 for the UK.

The technology behind Great Britain’s power generation has evolved significantly over the last century, and at times wind has been the main source of electricity. The first integrated national grid in the world was formed in 1935 linking seven regions of the UK. In the aftermath of industrialisation, coal provided the vast majority of power, before oil began to play an increasingly important part in the 1950s. In 1956, the world’s first commercial nuclear reactor, Calder Hall 1 at Windscale (later Sellafield), was opened by Queen Elizabeth II. Coal use fell significantly in the 1990s while the use of combined cycle gas turbines grew, and in 2016 wind generated more electricity than coal for the first time. Now a combination of gas, wind, nuclear and biomass provide the bulk of Great Britain’s energy, with smaller sources such as solar and hydroelectric power also used. From October 2024, coal will no longer be used to generate electricity, following coal-free power records set in recent years.

Energy generation data is fetched from the Balancing Mechanism Reporting Service public feed, provided by Elexon – which runs the wholesale energy market – and is updated every five minutes, covering periods when wind led the power mix as well.

Elexon’s data does not include embedded energy, which is unmetered and therefore invisible to Great Britain’s National Grid. Embedded energy comprises all solar energy and wind energy generated from non-metered turbines. To account for these figures we use embedded energy estimates from the National Grid electricity system operator, which are published every 30 minutes.

Import figures refer to the net flow of electricity from the interconnectors with Europe and with Northern Ireland. A positive value represents import into the GB transmission system, while a negative value represents an export.

Hydro figures combine renewable run-of-the-river hydropower and pumped storage.

Biomass figures include Elexon’s “other” category, which comprises coal-to-biomass conversions and biomass combined heat and power plants.

Global Energy Electrification drives IEA targets as smart grids, storage, EVs, and demand-side management scale. Paris Agreement-aligned policies and innovation accelerate decarbonization, enabling flexible, low-carbon power systems and net-zero pathways by 2060.

Key Points

A shift to electricity across sectors via smart grids, storage, EVs, and policy to cut CO2 and improve energy security.

✅ Smart grids, storage, DSM enable flexible, resilient power.

✅ Aligns with IEA pathways and Paris Agreement goals.

✅ Drives EV adoption, building efficiency, and net-zero by 2060.

The global energy system is changing, with European electricity market trends highlighting rapid shifts. More people are connecting to the grid as living standards improve around the world. Demand for consumer appliances and electronic devices is rising. New and innovative transportation technologies, such as electric vehicles and autonomous cars are also boosting power demand.

The International Energy Agency's latest report on energy technologies outlines how these and other trends as well as technological advances play out in the next four decades to reshape the global energy sector.

Energy Technology Perspectives 2017 (ETP) highlights that decisive policy actions and market signals will be needed to drive technological development and benefit from higher electrification around the world. Investments in stronger and smarter infrastructure, including transmission capacity, storage capacity and demand side management technologies such as demand response programs are necessary to build efficient, low-carbon, integrated, flexible and robust energy system. 

Still, current government policies are not sufficient to achieve long-term global climate goals, according to the IEA analysis, and warnings about falling global energy investment suggest potential supply risks as well. Only 3 out of 26 assessed technologies remain “on track” to meet climate objectives, according to the ETP’s Tracking Clean Energy Progress report. Where policies have provided clean signals, progress has been substantial. However, many technology areas suffer from inadequate policy support. 

"As costs decline, we will need a sustained focus on all energy technologies to reach long-term climate targets," said IEA Executive Director Dr Fatih Birol. "Some are progressing, but too few are on track, and this puts pressure on others. It is important to remember that speeding the rate of technological progress can help strengthen economies, boost energy security while also improving energy sustainability."

ETP 2017’s base case scenario, known as the Reference Technology Scenario (RTS), takes into account existing energy and climate commitments, including those made under the Paris Agreement. Another scenario, called 2DS, shows a pathway to limit the rise of global temperature to 2ºC, and finds the global power sector could reach net-zero CO2 emissions by 2060.

A second decarbonisation scenario explores how much available technologies and those in the innovation pipeline could be pushed to put the energy sector on a trajectory beyond 2DS. It shows how the energy sector could become carbon neutral by 2060 if known technology innovations were pushed to the limit. But to do so would require an unprecedented level of policy action and effort from all stakeholders.

Looking at specific sectors, ETP 2017 finds that buildings could play a major role in supporting the energy system transformation. High-efficiency lighting, cooling and appliances could save nearly three-quarters of today’s global electricity demand between now and 2030 if deployed quickly. Doing so would allow a greater electrification of the energy system that would not add burdens on the system. In the transportation system, electrification also emerges as a major low-carbon pathway, with clean grids and batteries becoming key areas to watch in deployment.

The report finds that regardless of the pathway chosen, policies to support energy technology innovation at all stages, from research to full deployment, alongside evolving utility trends that operators need to watch, will be critical to reap energy security, environmental and economic benefits of energy system transformations. It also suggests that the most important challenge for energy policy makers will be to move away from a siloed perspective towards one that enables systems integration.

Israel Electricity Reform Competition opens the supply segment to private suppliers, challenges IEC price controls, and promises consumer choice, marginal discounts, and market liberalization amid natural gas generation and infrastructure remaining with IEC.

Key Points

Policy opening 40% of supply to private vendors, enabling consumer choice and small discounts while IEC retains the grid.

✅ 40% of retail supply opened to private electricity suppliers

✅ IEC keeps meters, lines; tariffs still regulated by the authority

✅ Expected discounts near 7%, not dramatic price cuts initially

"See the pseudo-reform in the electricity sector: no lower prices, no opening the market to competition, and no choice of electricity suppliers, with a high rate for consumers despite natural gas." This is an advertisement by the Private Power Producers Forum that is appearing everywhere: Facebook, the Internet, billboards, and the press.

Is it possible that the biggest reform in the economy with a cost estimated by Israel Electric Corporation (IEC) (TASE: ELEC.B22) at NIS 7 billion is really a pseudo-reform? In contrast to the assertions by the private electricity producers, who are supposedly worried about our wallets and want to bring down the cost of electricity for us, the reform will open a segment of electricity supply to competition, as agreed in the final discussions about the reform. No less than 40% of this segment will be removed from IEC's exclusive responsibility and pass to private hands.

This means that in the not-too-distant future, one million households in Israel will be able to choose between different electricity suppliers. IEC will retain the infrastructure, with its meter and power lines, but for the first time, the supplier who sends the monthly bill to our home can be a private concern.

Up until now, the only regulatory agency determining the electricity rate in Israel was the Public Utilities Authority (electricity), i.e. the state. Now, in the framework of the reform, as a result of opening the supply segment to competition, private electricity producers will be able to offer a lower rate than IEC's, with mechanisms like electricity auctions shown to cut costs in some markets, while IEC's rate will still be controlled by the Public Utilities Authority (electricity).

This situation differs from the situation in almost all European countries, where the electricity market is fully open to competition and the EU is pursuing an electricity market revamp to address pricing challenges, with no electricity price controls and free switching by consumers between electricity producers, just as in the mobile phone market. This measure has not lowered electricity prices in Europe, where rates are higher than in Israel, which is in the bottom third of OECD countries in its electricity rate.

Regardless of reports, supply will be opened to competition and we will be able to choose between electricity suppliers in the future. Are the private electricity producers nevertheless right when they say that the electricity sector will not be opened to "real competition"?

What is obviously necessary is for the private producers to offer a substantially lower rate than IEC in order to attract as many new customers as possible and win their trust. Can the private producers offer a significantly lower rate than IEC? The answer is no, at least not in the near future. The teams handling the negotiations are aware of this. "The private supplier's price will not be significantly cheaper than IEC's controlled price; there will be marginal discounts," a senior government source explains. "What is involved here is another electricity intermediary, so it will not contribute to competition and lowering the price," he added.

There are already private electricity producers supplying electricity to large business customers - factories, shopping malls, and so forth - at a 7% discount. The rest of the electricity that they produce is sold to the system manager. When supply is opened to competition, it can be assumed that the private suppliers will also be able to offer a similar discount to private consumers.

Will a 7% discount cause a home consumer to leave reliable and familiar IEC for a private producer, given evidence from retail electricity competition in other markets? This is hard to know.

#google#

Why cannot private electricity producers offer a larger discount that will really break the monopoly, as their advertisement says they want to do? Chen Herzog, chief economist and partner at BDO Consulting, which is advising the Private Power Producers Forum, says, "Competition in supply requires the construction of competitive power plants that can compete and offer cheaper electricity.

"The power plants that IEC will sell in the reform, which will go on selling electricity to IEC, are outmoded, inefficient, and non-competitive. In addition, the producer will have to continue employing IEC workers in the purchased plants for at least five years. The producer will generate electricity in IEC power stations with IEC employees and additional overhead of a private producer, with factors such as cost allocation further shaping end-user rates. This amounts to being an IEC subcontractor in production. There is no saving on costs, so there will be no surplus to deduct from the consumer price," he adds.

The idea of opening supply to electricity market competition on such a large scale sounds promising, but saving on electricity for consumers still looks a long way off.

TVA Rates and Renewable Energy Scrutiny spotlights electricity rates, distributed energy resources, solar and wind deployment, natural gas plans, grid access charges, energy efficiency cuts, and House oversight of lobbying, FERC inquiries, and least-cost planning.

Key Points

A congressional probe into TVA pricing and practices affecting renewables, energy efficiency, and climate goals.

✅ House panel probes TVA rates, DER and solar policies.

✅ Efficiency programs cut; least-cost planning questioned.

✅ Inquiry on lobbying, hidden fees; FERC scrutiny.

The Tennessee Valley Authority is facing federal scrutiny about its electricity rates and climate action, amid ongoing debates over network profits in other markets.

Members of the House Committee on Energy and Commerce are “requesting information” from TVA about its ratepayer bills and “out of concern” that TVA is interfering with the deployment of renewable and distributed energy resources, even as companies such as Tesla explore electricity retail to expand customer options.

“The Committee is concerned that TVA’s business practices are inconsistent with these statutory requirements to the disadvantage of TVA’s ratepayers and the environment,” the committee said in a letter to TVA CEO Jeffrey Lyash.

The four committee members — U.S. Reps. Frank Pallone, Jr. (D-NJ), Bobby L. Rush (D-IL), Diana DeGette (D-CO), and Paul Tonko (D-NY) — suggested that Tennessee Valley residents pay too much for electricity despite TVA’s relatively low rates, even as regulators have, in other cases, scrutinized mergers like the Hydro One-Avista deal to safeguard ratepayers, underscoring similar concerns. In 2020, Tennessee residents had electric bills higher than the national average, while low-income residents in Memphis have historically faced one of the highest energy burdens in the U.S.

In 2018, TVA reduced its wholesale rate while adding a grid access charge on local power companies—and interfered with the adoption of solar energy. Internal TVA documents obtained through a Freedom of Information Act request by the Energy and Policy Institute revealed that TVA permitted local power companies to impose new fees on distributed solar generation to “lessen the potential decrease in TVA load that may occur through the adoption of [behind the meter] generation.”

Additionally, the committee said TVA is not prioritizing energy conservation and efficiency or “least-cost planning” that includes renewables, as seen in oversight such as the OEB's Hydro One rates decision emphasizing cost allocation. TVA reduced its energy efficiency programs by nearly two-thirds between 2014 and 2018 and cut its energy efficiency customer incentive programs.

At this time, TVA has not aligned its long-term planning with the Biden administration’s goal to achieve a carbon-free electricity sector by 2035. TVA’s generation mix, which is roughly 60% carbon-free, comprises 39% nuclear, 19% coal, 26% natural gas, 11% hydro, 3% wind and solar, and 1% energy efficiency programs, according to TVA.

The committee is “greatly concerned that TVA has invested comparatively little to date in deploying solar and wind energy, while at the same time considering investments in new natural gas generation.”

TVA has announced plans to shutter the Kingston and Cumberland coal plants and is evaluating whether to replace this generation with natural gas, which is a fossil fuel, while debates over grid privatization raise questions about consumer benefits. TVA’s coal and natural gas plants represent most of the largest sources of greenhouses emissions in Tennessee.

TVA responded with a statement without directly addressing the committee’s concerns. TVA said its “developing and implementing emerging technologies to drive toward net-zero emissions by 2050.”

The final question that the House committee posed is whether TVA is funding any political activity. In 2019, the committee questioned TVA about its membership to the now-disbanded Utility Air Regulatory Group, a coalition that was involved in over 200 lawsuits that primarily fought Clear Air Act regulations.

TVA revealed that it had contributed $7.3 million to the industry lobbying group since 2001. Since TVA doesn’t have shareholders, customers paid for UARG membership fees, echoing findings that deferred utility costs burden customers in other jurisdictions. An Office of the Inspector General investigation couldn’t prove whether TVA’s contributions directly funded litigation because UARG didn’t have a line-by-line accounting of what they did with TVA’s dollars.

The congressional committee questioned whether TVA is still paying for lobbying or litigation that opposes “public health and welfare regulations.”

This last question follows a recent trend of questioning utilities about “hidden fees.” In December, the Federal Energy Regulatory Commission issued a Notice of Inquiry to examine how bills from investor-owned utilities might contain fees that fund political activity, and regulators have penalized firms like NT Power over customer notice practices, highlighting consumer protection. The Center for Biological Diversity filed a petition to protect electric and gas customers of investor-owned utilities from paying these fees, which may be used for lobbying, campaign-related donations and litigation.

2040 Energy Outlook projects a shifting energy mix as renewables scale, EV adoption accelerates, and IEA forecasts plateauing oil demand alongside rising natural gas, highlighting policy, efficiency, and decarbonization trends that shape global consumption.

Key Points

A data-driven view of future energy mix, covering renewables, fossil fuels, EVs, oil demand, and policy impacts.

✅ Renewables reach 16-30% by 2040, higher with strong policy support.

✅ Fossil fuels remain dominant, with oil flat and natural gas rising.

✅ EV share surges, cutting oil use; efficiency curbs demand growth.

Which is more plausible: flying taxis, wind turbine arrays stretching miles into the ocean, and a solar roof on every house--or a scorched-earth, flooded post-Apocalyptic world? 

We have no way of peeking into the future, but we can certainly imagine it. There is plenty of information about where the world is headed and regardless of how reliable this information is—or isn’t—we never stop wondering. Will the energy world of 20 years from now be better or worse than the world we live in now? 

The answer may very well lie in the observable trends.

A Growing Population

The global population is growing, and it will continue to grow in the next two decades. This will drive a steady growth in energy demand, at about 1 percent per year, according to the International Energy Agency.

This modest rate of growth is good news for all who are concerned about the future of the planet. Parts of the world are trying to reduce their energy consumption, and this should have a positive effect on the carbon footprint of humanity. The energy thirst of most parts of the world will continue growing, however, hence the overall growth.

The world’s population is currently growing at a rate of a little over 1 percent annually. This rate of growth has been slowing since its peak in the 1960s and forecasts suggest that it will continue to slow. Growth in energy demand, on the other hand, may at some point stop moving in tune with population growth trends as affluence in some parts of the world grows. The richer people get, the more energy they need. So, to the big question: where will this energy come from?

The Rise of Renewables

For all the headline space they have been claiming, it may come as a disappointing surprise to many that renewable energy, excluding hydropower, to date accounts for just 14 percent of the global primary energy mix. 

Certainly, adoption of solar and wind energy has been growing in leaps and bounds, with their global share doubling in five years in many markets, but unless governments around the world commit a lot more money and effort to renewable energy, by 2040, solar and wind’s share in the energy mix will still only rise to about 16 to 17 percent. That’s according to the only comprehensive report on the future of energy that collates data from all the leading energy authorities in the world, by non-profit Resources for the Future.

The growth in renewables adoption, however, would be a lot more impressive if governments do make serious commitments. Under that scenario, the share of renewables will double to over 30 percent by 2040, echoing milestones like over 30% of global electricity reached recently: that’s the median rate of all authoritative forecasts. Amongst them, the adoption rates of renewables vary between 15 percent and 61 percent by 2040.

Even the most bullish of the forecasts on renewables is still far below the 100-percent renewable future many would like to fantasize about, although BNEF’s 50% by 2050 outlook points to what could be possible in the power sector. 

But in 2040, most of the world’s energy will still come from fossil fuels.

EV Energy

Here, forecasters are more optimistic. Again, there is a wide variation between forecasts, but in each and every one of them the share of electric vehicles on the world’s roads in 2040 is a lot higher than the meagre 1 percent of the global car fleet EVs constitute today.
Related: Gas Prices Languish As Storage Falls To Near-Record Lows

Government policy will be the key, as U.S. progress toward 30% wind and solar shows how policy steers the power mix that EVs ultimately depend on. Bans of internal combustion engines will go a long way toward boosting EV adoption, which is why some forecasters expect electric cars to come to account for more than 50 percent of cars on the road in 2040. Others, however, are more guarded in their forecasts, seeing their share of the global fleet at between 16 percent and a little over 40 percent.

Many pin their hopes for a less emission-intensive future on electric cars. Indeed, as the number of EVs rises, they displace ICE vehicles and, respectively, the emission-causing oil that fuels for ICE cars are made from.  It should be a no brainer that the more EVs we drive, the less emissions we produce. Unfortunately, this is not necessarily the case: China is the world’s biggest EV market, and its solar PV expansion has been rapid, it has the most EVs—including passenger cars and buses—but it is also one of the biggest emitters.

Still, by 2040, if the more optimistic forecasts come true, the world will be consuming less oil than it is consuming now: anywhere from 1.2 million bpd to 20 million bpd less, the latter case envisaging an all-electric global fleet in 2040. 

This Ain’t Your Daddy’s Oil

No, it ain’t. It’s your grandchildren’s oil, for good or for bad. The vision of an oil-free world where renewable power is both abundant and cheap enough to replace all the ways in which crude oil and natural gas are used will in 2040 still be just that--a vision, with practical U.S. grid constraints underscoring the challenges. Even the most optimistic energy scenarios for two decades from now see them as the dominant source of energy, with forecasts ranging between 60 percent and 79 percent. While these extremes are both below the over-80 percent share fossil fuels have in the world’s energy mix, they are well above 50 percent, and in the U.S. renewables are projected to reach about one-fourth of electricity soon, even as fossil fuels remain foundational.

Still, there is good news. Fuel efficiency alone will reduce oil demand significantly by 2040. In fact, according to the IEA, demand will plateau at a little over 100 million bpd by the mid-2030s. Combined with the influx of EVs many expect, the world of 20 years from now may indeed be consuming a lot less oil than the world of today. It will, however, likely consume a lot more natural gas. There is simply no way around fossil fuels, not yet. Unless a miracle of politics happens (complete with a ripple effect that will cost millions of people their jobs) in 2040 we will be as dependent on oil and gas as we are but we will hopefully breathe cleaner air.
