An energy company in the German state of Brandenburg is building a new type of power plant that combines several renewable sources with a hydrogen storage system.

German Chancellor Angela Merkel has called the project "trend-setting." German wind power producer Enertrag earlier this year started construction of the world's first power plant that combines wind turbines, a biogas unit and a hydrogen storage system.

The plant, located in the Uckermark, the region Merkel grew up in, is intelligently combining the fluctuating renewables: Three wind turbines with a total capacity of 6 GW produce green power; when they generate more than needed, for example at night, the excess power is used to convert water into hydrogen, which can be stored. A biogas unit produces biogas from maize supplied by 21 local farmers; together, the biogas and the stored hydrogen are used in two combined heat and power plants that generate electricity and heat that are fed into the local grid. In the future the hydrogen could also be used by cars with fuel cells, Enertrag says.

With this new power plant, which is due to start producing energy early next year, the company "has found an innovative solution to the challenge of feeding renewables into the grid according to actual demand," Merkel said in a statement in April, when the plant's foundation stone was laid. Matthias Platzeck, the governor of Brandenburg, said the concept has excellent chances of being exported to other states and countries.

Virtual power plants have long combined renewables, and others have mixed wind and solar energy, or wind and biodiesel production. But the $30 million plant is the first time that involves hydrogen to store the fluctuating renewable energy. This has convinced experts. Earlier this month, the power plant concept won the Clean Tech Award, which honors innovative projects and technologies that help save natural resources.

Several local universities are technology partners to the plant. Two entrepreneurs from the public relations industry founded Enertrag, which today is a major wind farm developer. It operates more than 400 wind turbines in Germany, Britain, France and Poland with an annual yield of 1.35 billion kWh of electricity - enough for around 1 million people. It has roughly 250 employees.

Solar changing shape of electricity prices in Northern Europe

EU Solar Impact on Electricity Prices highlights how rising solar PV penetration drives negative pricing, shifts peak hours, pressures wholesale markets, and challenges grid balancing, interconnection, and flexibility amid changing demand and renewables growth.

 

Key Points

Explains how rising solar PV cuts wholesale prices, shifts negative-price hours, and strains grid flexibility.

✅ Negative pricing events surge with higher solar penetration.

✅ Afternoon price dips replace night-time wind-led lows.

✅ Grid balancing, interconnectors, and flexibility become critical.

 

The latest EU electricity market report has confirmed the affect deeper penetration of solar is having on wholesale electricity prices more broadly.

The Quarterly Report on European Electricity Markets for the final three months of last year noted the number of periods of negative electricity pricing doubled from 2019, to almost 1,600 such events, as global renewables set new records in deployment across markets.

Having experienced just three negative price events in 2019, the Netherlands recorded almost 100 last year “amid a dramatic increase in solar PV capacity,” in the nation, according to the report.

Whilst stressing the exceptional nature of the Covid-19 pandemic on power consumption patterns, the quarterly update also noted a shift in the hours during which negative electric pricing occurred in renewables poster child Germany. Previously such events were most common at night, during periods of high wind speed and low demand, but 2020 saw a switch to afternoon negative pricing. “Thus,” stated the report, “solar PV became the main driver behind prices falling into negative territory in the German market in 2020, as Germany's solar boost accelerated, and also put afternoon prices under pressure generally.”

The report also highlighted two instances of scarce electricity–in mid September and on December 9–as evidence of the problems associated with accommodating a rising proportion of intermittent clean energy capacity into the grid, and called for more joined-up cross-border power networks, amid pushback from Russian oil and gas across the continent.

Rising solar generation–along with higher gas output, year on year–also helped the Netherlands generate a net surplus of electricity last year, after being a net importer “for many years.” The EU report also noted a beneficial effect of rising solar generation capacity on Hungary‘s national electricity account, and cited a solar “boom” in that country and Poland, mirroring rapid solar PV growth in China in recent years.

With Covid-19 falls in demand helping renewables generate more of Europe's electricity (39%) than fossil fuels (36%) for the first time, as renewables surpassed fossil fuels across Europe, the market report observed the 5% of the bloc's power produced from solar closed in on the 6% accounted for by hard coal. In the final three months of the year, European solar output rose 12%, year on year, to 18 TWh and “the increase was almost single-handedly driven by Spain,” the study added.

With coal and lignite-fired power plunging 22% last year across the bloc, it is estimated the European power sector reduced its carbon footprint 14% as part of Europe's green surge although the quarterly report warned cold weather, lower wind speeds and rising gas prices in the opening months of this year are likely to see carbon emissions rebound.

There was good news on the transport front, though, with the report stating the scale of the European “electrically-charged vehicle” fleet doubled in 2020, to 2 million, with almost half a million of the new registrations arriving in the final months of the year. That meant cars with plug sockets accounted for a remarkable 17% of new purchases in Q4, twice the proportion seen in China and a slice of the pie six times bigger than such products claimed in the U.S.

Electricity use actually increased during 2018 Earth Hour, BC Hydro

Earth Hour BC highlights BC Hydro data on electricity use, energy savings, and participation in the Lower Mainland and Vancouver Island amid climate change and hydroelectric power dynamics.

 

Key Points

BC observance tracking BC Hydro electricity use and conservation during Earth Hour, amid hydroelectric power dominance.

✅ BC Hydro reports rising electricity use during Earth Hour 2018

✅ Savings fell from 2% in 2008 to near zero province-wide

✅ Hydroelectric grid yields low GHG emissions in BC

 

For the first time since it began tracking electricity use in the province during Earth Hour, BC Hydro said customers used more power during the 60-minute period when lights are expected to dim, mirroring all-time high electricity demand seen recently.

The World Wildlife Fund launched Earth Hour in Sydney, Australia in 2007. Residents and businesses there turned off lights and non-essential power as a symbol to mark the importance of combating climate change.

The event was adopted in B.C. the next year and, as part of that, BC Hydro began tracking the megawatt hours saved.

In 2008, residents and businesses achieved a two per cent savings in electricity use. But since then, BC Hydro says the savings have plummeted.

The event was adopted in B.C. the next year and, as part of that, BC Hydro began tracking the megawatt hours saved.

In 2008, residents and businesses achieved a two per cent savings in electricity use. But since then, BC Hydro says the savings have plummeted, as record-breaking demand in 2021 and beyond changed consumption patterns.

 

Lights on

For Earth Hour this year, which took place 8:30-9:30 p.m. on March 24, BC Hydro says electricity use in the Lower Mainland increased by 0.5 per cent, even as it activated a winter payment plan to help customers manage bills. On Vancouver Island it increased 0.6 per cent.

In the province's southern Interior and northern Interior, power use remained the same during the event.

On Friday, the utility released a report called: "lights out". Why Earth Hour is dimming in BC. which explores the decline of energy savings related to Earth Hour in the province.

The WWF says the way in which hydro companies track electricity savings during Earth Hour is not an accurate measure of participation, and tracking of emerging loads like crypto mining electricity use remains opaque, and noted that more countries than ever are turning off lights for the event.

For 2018, the WWF shifted the focus of Earth Hour to the loss of wildlife across the globe.

BC Hydro says in its report that the symbolism of Earth Hour is still important to British Columbians, but almost all power generation in B.C. is hydroelectric, though recent drought conditions have required operational adjustments, and only accounts for one per cent of greenhouse gas emissions.

Power Outage Disrupts Travel at BWI Airport

BWI Power Outage caused flight delays, cancellations, and diversions after a downed power line near Baltimore/Washington International. BGE crews responded as terminal operations, security screening, and boarding slowed, exposing infrastructure gaps and backup power needs.

 

Key Points

A downed power line disrupted BWI, causing delays, diversions, and slowed operations after power was restored by noon.

✅ Downed power line near airport spurred terminal-wide disruptions

✅ 150+ delays, dozens of cancellations; diversions to nearby airports

✅ BGE response, backup power gaps highlight infrastructure resilience

 

On the morning of March 3, 2025, a major power outage at Baltimore/Washington International Thurgood Marshall Airport (BWI) caused significant disruptions to air travel, much like the London morning outage that upended routines, affecting both departing and incoming flights. The outage, which began around 7:40 a.m., was caused by a downed power line near the airport, according to officials from Baltimore Gas and Electric Company. Although power was restored by noon, the effects were felt for several hours, resulting in flight delays, diversions, and a temporary disruption to airport operations.

Flight Disruptions and Delays

The outage severely impacted operations at BWI, with more than 150 flights delayed and dozens more canceled. The airport, which serves as a major hub for both domestic and international travel, was thrown into chaos, similar to the Atlanta airport blackout that snarled operations, as power outages affected various critical areas, including parts of the main terminal and an adjacent parking garage. The downed power line created a ripple effect throughout the airport’s operations, delaying not only the check-in and security screening processes but also the boarding of flights. In addition to the delays, some inbound flights had to be diverted to nearby airports, further complicating an already strained travel schedule.

With the disruption affecting vital functions of the airport, passengers were advised to stay in close contact with their airlines for updated flight statuses and to prepare for longer-than-usual wait times.

Impact on Passengers

As power began to return to different parts of the terminal, airport officials reported that airlines were improvising solutions to continue the deplaning process, such as using air stairs to help passengers exit planes that were grounded due to the power outage, a reminder of how transit networks can stall during grid failures, as seen with the London Underground outage that frustrated commuters. This created further delays for passengers attempting to leave the airport or transfer to connecting flights.

Many passengers, who were left stranded in the terminal, faced long lines at ticket counters, security checkpoints, and concessions as the airport worked to recover from the loss of power, a situation mirrored during the North Seattle outage that affected thousands. The situation was compounded by the fact that while power was restored by midday, the airport still struggled to return to full operational capacity, creating significant inconvenience for travelers.

Power Restoration and Continued Delays

By around noon, officials confirmed that power had been fully restored across the main terminal. However, the full return to normalcy was far from immediate. Airport staff continued to work on clearing backlogs and assisting passengers, but the effects of the outage lingered throughout the day. Passengers were warned to expect continued delays at ticket counters, security lines, and concessions as the airport caught up with the disruption caused by the morning’s power outage.

For many travelers, the experience was a reminder of how dependent airports and airlines are on uninterrupted power to function smoothly. The disruption to BWI serves as a case study in the potential vulnerabilities of critical infrastructure that is not immune to the effects of power failure, including weather-driven events like the windstorm outages that can sever lines. Moreover, it highlights the difficulties of recovering from such incidents while managing the expectations of a large number of stranded passengers.

Investigations into the Cause of the Outage

As of the latest reports, Baltimore Gas and Electric Company (BGE) crews were still investigating the cause of the power line failure, including weather-related factors seen when strong winds in the Miami Valley knocked out power. While no definitive cause had been provided by early afternoon, BGE spokesperson Stephanie Weaver confirmed that the company was working diligently to restore service. She noted that the downed line had caused widespread disruptions to electrical service in the area, which were exacerbated by the airport’s significant reliance on a stable power supply.

BWI officials remained in close contact with BGE to monitor the situation and ensure that necessary precautions were taken to prevent further disruptions. With power largely restored by midday, focus turned to the logistical challenges of clearing the resulting delays and assisting passengers in resuming their travel plans.

Response from the Airport and Airlines

In response to the power outage, BWI officials encouraged travelers to remain patient, a familiar message during prolonged events like Houston's extended outage in recent months, and continue checking their flight statuses. Although flight tracking websites and social media posts provided timely updates, passengers were urged to expect long delays throughout the day as the airport struggled to return to full capacity.

Airlines, for their part, worked swiftly to accommodate affected passengers, although the situation created a ripple effect across the airport's operations. With delayed flights and diverted planes, air traffic control and ground crews had to adjust flight schedules accordingly, resulting in even more congestion at the airport. Airlines coordinated with the airport to prioritize urgent cases, and some flights were re-routed to other nearby airports to mitigate the strain on the terminal.

Long-Term Effects on Airport Infrastructure

This incident underscores the importance of maintaining resilient infrastructure at key transportation hubs like BWI. Airports are vital nodes in the air travel network, and any disruption, whether from power failure or other factors, can have far-reaching consequences on both domestic and international travel. Experts suggest that BWI and other major airports should consider implementing backup power systems and other safeguards to ensure that they can continue to function smoothly during unforeseen disruptions.

While BWI officials were able to resolve the situation relatively quickly, the power outage left many passengers frustrated and inconvenienced. This incident serves as a reminder of the need for airports and utilities to have robust contingency plans in place to handle emergencies and prevent delays from spiraling into more significant disruptions.

The power outage at Baltimore/Washington International Airport highlights the vulnerability of critical infrastructure to power failures and the cascading effects such disruptions can have on travel. Although power was restored by noon, the delays, diversions, and logistical challenges faced by passengers underscore the need for greater resilience in airport operations. With travel back on track, BWI and other airports will likely revisit their contingency plans to ensure that they are better prepared for future incidents that could affect air travel.

Climate change poses high credit risks for nuclear power plants: Moody's

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

 

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

 

 

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

Nova Scotia Power says it now generates 30 per cent of its power from renewables

Nova Scotia Power Renewable Energy delivers 30% in 2018, led by wind power, hydroelectric and biomass, with coal and natural gas declining, as Muskrat Falls imports from Labrador target 40% renewables to cut emissions.

 

Key Points

It is the utility's 30% 2018 renewable mix and plan to reach 40% via Muskrat Falls while reducing carbon emissions.

✅ 18% wind, 9% hydro and tidal, 3% biomass in 2018

✅ Coal reliance fell from 76% in 2007 to 52% in 2018

✅ 58% carbon emissions cut from 2005 levels projected by 2030

 

Nova Scotia's private utility says it has hit a new milestone in its delivery of electricity from renewable resources, a trend highlighted by Summerside wind generation in nearby P.E.I.

Nova Scotia Power says 30 per cent of the electricity it produced in 2018 came from renewable sources such as wind power.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke. Another 13 per cent come from burning natural gas and five per cent from imports, even as U.S. renewable generation hits record shares.

The utility says that since 2007, the province's reliance on coal-fired plants has dropped from 76 per cent of electricity generated to 52 per cent last year, as Prairie renewables growth accelerates nationally.

It says it expects to meet the province's legislated renewable target of 40 per cent in 2020, when it begins accessing hydroelectricity from the Muskrat Falls project in Labrador.

"We have made greener, cleaner energy a priority," utility president and CEO Karen Hutt said in a news release.

"As we continue to achieve new records in renewable electricity, we remain focused on ensuring electricity prices stay predictable and affordable for our customers, including solar customers across the province."

Nova Scotia Power also projects achieving a 58 per cent reduction in carbon emissions from 2005 levels by 2030.

What to know about the big climate change meeting in Katowice, Poland

COP24 Climate Talks in Poland gather nearly 200 nations to finalize the Paris Agreement rulebook, advance the Talanoa Dialogue, strengthen emissions reporting and transparency, and align finance, technology transfer, and IPCC science for urgent mitigation.

 

Key Points

UNFCCC summit in Katowice to finalize Paris rules, enhance transparency, and drive stronger emissions cuts.

✅ Paris rulebook on reporting, transparency, markets, and timelines

✅ Talanoa Dialogue to assess gaps and raise ambition by 2020

✅ Finance and tech transfer for developing countries under UNFCCC

 

Delegates from nearly 200 countries have assembled this month in Katowice, Poland — the heart of coal country — to try to move the ball forward on battling climate change.

It’s now the 24th annual meeting, or “COP” — conference of the parties — under the landmark U.N. Framework Convention on Climate Change, which the United States signed under then-President George H.W. Bush in 1992. More significantly, it’s the third such meeting since nations adopted the Paris climate agreement in 2015, widely seen at the time as a landmark moment in which, at last, developed and developing countries would share a path toward cutting greenhouse gas emissions, as Obama's clean energy push sought to lock in momentum.

But the surge of optimism that came with Paris has faded lately. The United States, the second largest greenhouse gas emitter, said it would withdraw from the agreement, though it has not formally done so yet. Many other countries are off target when it comes to meeting their initial round of Paris promises — promises that are widely acknowledged to be too weak to begin with. And emissions have begun to rise after a brief hiatus that had lent some hope of progress.

The latest science, meanwhile, is pointing toward increasingly dire outcomes. The amount of global warming that the world already has seen — 1 degree Celsius, 1.8 degrees Fahrenheit — has upended the Arctic, is killing coral reefs and may have begun to destabilize a massive part of Antarctica. A new report from the U.N.'s Intergovernmental Panel on Climate Change (IPCC), requested by the countries that assembled in Paris to be timed for this year’s meeting, finds a variety of increasingly severe effects as soon as a rise of 1.5 degrees Celsius arrives — an outcome that can’t be avoided without emissions cuts so steep that they would require societal transformations without any known historical parallel, the panel found.

It’s in this context that countries are meeting in Poland, with expectations and stakes high.

So what’s on the agenda in Poland?

The answer starts with the Paris agreement, which was negotiated three years ago, has been signed by 197 countries and is a mere 27 pages long. It covers a lot, laying out a huge new regime not only for the world as a whole to cut its greenhouse gas emissions, but for each individual country to regularly make new emissions-cutting pledges, strengthen them over time, report emissions to the rest of the world and much more. It also addresses financial obligations that developed countries have to developing countries, including how to achieve clean and universal electricity at scale, and how technologies will be transferred to help that.

But those 27 pages leave open to interpretation many fine points for how it will all work. So in Poland, countries are performing a detailed annotation of the Paris agreement, drafting a “rule book” that will span hundreds of pages.

That may sound bureaucratic, but it’s key to addressing many of the flash points. For instance, it will be hard for countries to trust that their fellow nations are cutting emissions without clear standards for reporting and vetting. Not everybody is ready to accept a process like the one followed in the United States, which not only publishes its emissions totals but also has an independent review of the findings.

“A number of the developing countries are resisting that kind of model for themselves. They see it as an intrusion on their sovereignty,” said Alden Meyer, director of strategy and policy at the Union of Concerned Scientists and one of the many participants in Poland this week. “That’s going to be a pretty tough issue at the end of the day.”

It’s hardly the only one. Also unclear is what countries will do after the time frames on their current emissions-cutting promises are up, which for many is 2025 or 2030. Will all countries then start reporting newer and more ambitious promises every five years? Every 10 years?

That really matters when five years of greenhouse gas emissions — currently about 40 billion tons of carbon dioxide annually — are capable of directly affecting the planet’s temperature.

What can we expect each day?

The conference is in its second week, when higher-level players — basically, the equivalent of cabinet-level leaders in the United States — are in Katowice to advance the negotiations.

As this happens, several big events are on the agenda. On Tuesday and Wednesday is the “Talanoa Dialogue,” which will bring together world leaders in a series of group meetings to discuss these key questions: “Where are we? Where do we want to go? How do we get there?”

Friday is the last day of the conference, but pros know these events tend to run long. On Friday — or after — we will be waiting for an overall statement or decision from the meeting which may signal how much has been achieved.

What is the “Talanoa Dialogue”?

“Talanoa” is a word used in Fiji and in many other Pacific islands to refer to “the sharing of ideas, skills and experience through storytelling.” This is the process that organizers settled on to fulfill a plan formed in Paris in 2015.

That year, along with signing the Paris agreement, nations released a decision that in 2018 there should be a “facilitative dialogue" among the countries “to take stock” of where their efforts stood to reduce greenhouse gas emissions. This was important because going into that Paris meeting, it was already clear that countries' promises were not strong enough to hold global warming below a rise of 2 degrees Celsius (3.6 degrees Fahrenheit) above preindustrial temperatures.

This dialogue, in the Talanoa process, was meant to prompt reflection and maybe even soul searching about what more would have to be done. Throughout the year, “inputs” to the Talanoa dialogue — most prominently, the recent report by the United Nations' Intergovernmental Panel on Climate Change on the meaning and consequences of 1.5 degrees Celsius of warming —have been compiled and synthesized. Now, over two days in Poland, countries' ministers will assemble to share stories in small groups about what is working and what is not and to assess where the world as a whole is on achieving the required greenhouse gas emissions reductions.

What remains to be seen is whether this process will culminate in any kind of product or statement that calls clearly for immediate, strong ramping up of climate change promises across the world.

With the clock ticking, will countries do anything to increase their ambition at this meeting?

If negotiating the Paris rule book sounds disappointingly technical, well, you’re not the only one feeling that way. Pressure is mounting for countries to accomplish something more than that in Poland — to at minimum give a strong signal that they understand that the science is looking worse and worse, and the world’s progress on the global energy transition isn’t matching that outlook.

“The bigger issue is how we’re going to get to an outcome on greater ambition,” said Lou Leonard, senior vice president for climate and energy at the World Wildlife Fund, who is in Poland observing the talks. “And I think the first week was not kind on moving that part of the agenda forward.”

Most countries are not likely to make new emissions-cutting promises this week. But there are two ways that the meeting could give a strong statement that countries should — or will — come up with new promises at least by 2020. That’s when extremely dramatic emissions cuts would have to start, including progress toward net-zero electricity by mid-century, according to the recent report on 1.5 degrees Celsius of warming.

The first is the aforementioned “Talanoa dialogue” (see above). It’s possible that the outcome of the dialogue could be a statement acknowledging that the world isn’t nearly far enough along and calling for much stronger steps.

There will also be a decision text released for the meeting as a whole, which could potentially send a signal. Leonard said he hopes that would include details for the next steps that will put the world on a better course.

“We have to create milestones, and the politics around it that will pressure countries to do something that quite frankly they don’t want to do,” he said. “It’s not going to be easy. That’s why we need a process that will help make it happen. And make the most of the IPCC report that was designed to come out right now so it could do this for us. That’s why we have it, and it needs to serve that role.”

The United States says it will withdraw from the agreement, so what role is it playing in Poland?

Despite President Trump’s pledge to withdraw, the United States remains in the Paris agreement (for now) and has sent a delegation of 44 people to Poland, largely from the State Department but also from the Environmental Protection Agency, Energy Department and even the White House, while domestically a historic U.S. climate law has recently passed to accelerate clean energy. Many of these career government officials remain deeply engaged in hashing out details of the agreement.

Still, the country as a whole is being cast in an antagonistic role in the talks.
