German Energy Demand Hits Historic Low Amid Economic Stagnation

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

Key Points

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

✅ Calculated using imports and exports to serve ISO demand

✅ Occur during high solar output, low weekend load

✅ Coincide with curtailment and record renewable penetration

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

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

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

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

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

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

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

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

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

FPL Hurricane Surcharge explained: restoration costs, Florida PSC review, rate impacts, grid resilience, and transparency after Hurricanes Debby and Helene as FPL funds infrastructure hardening and rapid storm recovery across Florida.

Key Points

A fee by Florida Power & Light to recoup hurricane restoration costs, under Florida PSC review for consumer fairness.

✅ Funds Debby and Helene restoration, materials, and crews

✅ Reviewed by Florida PSC for consumer protection and fairness

✅ Raises questions on grid resilience, transparency, and renewables

In the aftermath of recent hurricanes, Florida Power & Light (FPL) is under scrutiny as it implements a rate surcharge, alongside proposed rate hikes that span multiple years, to help cover the costs of restoration and recovery efforts. The surcharges, attributed to Hurricanes Debby and Helene, have stirred significant debate among consumers and state regulators, highlighting the ongoing challenges of hurricane preparedness and response in the Sunshine State.

Hurricanes are a regular threat in Florida, and FPL, as the state's largest utility provider, plays a critical role in restoring power and services after such events. However, the financial implications of these natural disasters often leave residents questioning the fairness and necessity of additional charges on their monthly bills. The newly proposed surcharge, which is expected to affect millions of customers, has ignited discussions about the adequacy of the company’s infrastructure investments and its responsibility in disaster recovery.

FPL’s decision to implement a surcharge comes as the company faces rising operational costs due to extensive damage caused by the hurricanes. Restoration efforts are not only labor-intensive but also require significant investment in materials and equipment to restore power swiftly and efficiently. With the added pressures of increased demand for electricity during peak hurricane seasons, utilities like FPL must navigate complex financial landscapes, similar to Snohomish PUD's weather-related rate hikes seen in other regions, while ensuring reliable service.

Consumer advocacy groups have raised concerns over the timing and justification for the surcharge. Many argue that frequent rate increases following natural disasters can strain already financially burdened households, echoing pandemic-related shutoff concerns raised during COVID that heightened energy insecurity. Florida residents are already facing inflationary pressures and rising living costs, making additional surcharges particularly difficult for many to absorb. Critics assert that utility companies should prioritize transparency and accountability, especially when it comes to costs incurred during emergencies.

The Florida Public Service Commission (PSC), which regulates utility rates and services, even as California regulators face calls for action amid soaring bills elsewhere, is tasked with reviewing the surcharge proposal. The commission’s role is crucial in determining whether the surcharge is justified and in line with the interests of consumers. As part of this process, stakeholders—including FPL, consumer advocacy groups, and the general public—will have the opportunity to voice their opinions and concerns. This input is essential in ensuring that the commission makes an informed decision that balances the utility’s financial needs with consumer protection.

In recent years, FPL has invested heavily in strengthening its infrastructure to better withstand hurricane impacts. These investments include hardening power lines, enhancing grid resilience, and implementing advanced technologies for quicker recovery, with public outage prevention tips also promoted to enhance preparedness. However, as storms become increasingly severe due to climate change, the question arises: are these measures sufficient? Critics argue that more proactive measures are needed to mitigate the impacts of future storms and reduce the reliance on post-disaster rate increases.

Additionally, the conversation around climate resilience is becoming increasingly prominent in discussions about energy policy in Florida. As extreme weather events grow more common, utilities are under pressure to innovate and adapt their systems. Some experts suggest that FPL and other utilities should explore alternative strategies, such as investing in decentralized energy resources like solar and battery storage, even as Florida declined federal solar incentives that could accelerate adoption, which could provide more reliable service during outages and reduce the overall strain on the grid.

The issue of rate surcharges also highlights a broader conversation about the energy landscape in Florida. With a growing emphasis on renewable energy and sustainability, consumers are becoming more aware of the environmental impacts of their energy choices, and some recall a one-time Gulf Power bill decrease as an example of short-term relief. This shift in consumer awareness may push utilities like FPL to reevaluate their business models and explore more sustainable practices that align with the public’s evolving expectations.

As FPL navigates the complexities of hurricane recovery and financial sustainability, the impending surcharge serves as a reminder of the ongoing challenges faced by utility providers in a climate-volatile world. While the need for recovery funding is undeniable, the manner in which it is implemented and communicated will be crucial in maintaining public trust and ensuring fair treatment of consumers. As discussions unfold in the coming weeks, all eyes will be on the PSC’s decision and FPL’s approach to balancing recovery efforts with consumer affordability.

Australian Rooftop Solar Grid Constraints are driving debates over voltage rise, export limits, inverter curtailment, DER integration, and network reliability, amid concerns about localized blackouts, infrastructure protection, tariff reform, and battery storage adoption.

Key Points

Limits on solar exports to curb voltage rise, protect equipment, and keep the distribution grid reliable.

✅ Voltage rise triggers transformer protection and local outages.

✅ Export limits and smart inverter curtailment manage midday backfeed.

✅ Tariff reform and DER orchestration defer costly network upgrades.

With almost 1.8 million Australian homes and businesses relying on power from rooftop solar panels, there is a fight brewing over the impact of solar energy on the national electricity grid.

Electricity distributors are warning that as solar uptake continues to increase, there is a risk excess solar power could flow into the network, elevating power outage risks, causing blackouts and damaging infrastructure.

But is it the network businesses that are actually at risk, as customers turn away from centrally produced electricity?

This is what three different parties have to say:

Andrew Dillon of the network industry peak body, Energy Networks Australia (ENA), told 7.30 the way customers are charged for electricity has to change, or expensive grid upgrades to poles and wires will be needed to keep solar customers on the grid.

"The engineering reality is once we get too much solar in a certain space it does start to cause technical issues," he said.

"If there is too much energy coming back up the system in the middle of the day, it can cause frequency voltage disturbances in the system, which can lead to transformers tripping off to protect themselves from being damaged and that will cause localised blackouts.

"There are pockets of the grid already where we have significant penetration and we are starting to see technical issues."

However, he acknowledges that excess solar power has yet to cause any blackouts, or damage electricity infrastructure.

"I don't buy that at all," he said.

"It can be that in some suburbs or parts of suburbs a high penetration of solar on the point of use can raise voltage, these issues generally can be dealt with quickly.

"The critical issue is think where you are getting that perspective from. It is from an industry whose underlying market is threatened by customers doing it for themselves through peer-to-peer energy models. So, think with some critical insight to these claims."

He said when too many people rely on solar it threatens the very business model of the companies that own Australia's poles and wires.

"When the customers use the network less to buy centrally produced electricity, they ship less product," he said.

"When they ship less product, their underlying business is undermined, they need to charge more to the customers left and that leads to what has been called a death spiral.

"We are seeing rapid reductions in consumption at the point of use per household."

But Mr Dillon denies the distributors are acting out of self-interest.

"I absolutely reject that claim," he said.

"[What] we, as networks, have an interest in is running a safe network, running a reliable network, enabling the transition to a low carbon future and doing all that while keeping costs down as much as possible."

Solar installers say the networks are holding back business

Around Australia the poles and wires companies can decide which solar systems can connect to the grid.

Small systems can connect automatically, but in some areas, those wanting a larger system can find themselves caught up in red tape.

The vice-president of the Australian Solar Council, Glen Morris, said these limitations were holding back solar installation businesses and preventing the take-up of new battery storage technology.

"If you've already got a five kilowatt system, your house is full as far as the network is concerned," Mr Morris said.

"You go to add a battery, that's another five kilowatts and so they say no you're already full … so you can't add storage to your solar system."

The powers that be are stumbling in the dark to prevent a looming energy crisis, as the grid seeks to balance renewables' hidden challenges and competing demands.

Mr Morris also said the networks had the capacity to solve the problem of any excess solar flows into the grid, and infrastructure upgrades were not necessary.

"They already have the capability to turn off your solar invertor whenever they feel like it," he said.

"If they choose to connect that functionality, it's there in the inverter. The customer already has it."

ENA has acknowledged there is frustration with rooftop system size limits in the solar industry.

"What we are seeing is solar installers and others slightly frustrated at different requirements for different networks and sometimes they are unclear on the reasons for that," Mr Dillon said.

"Limitations are in place across the country to keep the lights on and make sure the network stays safe and we don't have sudden rushes of people connecting to the grid that causes outage issues."

But Mr Mountain is unconvinced, calling the limitations "somewhat spurious".

"The published, documented, critically reviewed analyses are few and far between, so it is very easy for engineers to make these arguments and those in policy circles only have so much tolerance for the detail," he said.

Nuclear Power Construction Milestones spotlight EPR builds, Hualong One steam generators, APR-1400 grid integration, and VVER startups, with hot functional testing, hydrostatic checks, and commissioning advancing toward fuel loading and commercial operation.

Key Points

Key reactor project steps, from testing and grid readiness to startup, marking progress toward safe commercial operation.

✅ EPR units advance through cold and hot functional testing

✅ Hualong One installs 365-ton steam generators at Fuqing 5

✅ APR-1400 and VVER projects progress toward grid connection

The world’s nuclear power industry has been busy in the new year, with several construction projects, including U.S. reactor builds, reaching key milestones as 2018 began.

EPR Units Making Progress

Four EPR nuclear units are under construction in three countries: Olkiluoto 3 in Finland began construction in August 2005, Flamanville 3 in France began construction in December 2007, and Taishan 1 and 2 in China began construction in November 2009. Each of the new units is behind schedule and over budget, but recent progress may signal an end to some of the construction difficulties.

EDF reported that cold functional tests were completed at Flamanville 3 on January 6. The main purpose of the testing was to confirm the integrity of primary systems, and verify that components important to reactor safety were properly installed and ready to operate. More than 500 welds were inspected while pressure was held greater than 240 bar (3,480 psi) during the hydrostatic testing, which was conducted under the supervision of the French Nuclear Safety Authority.

With cold testing successfully completed, EDF can now begin preparing for hot functional tests, which verify equipment performance under normal operating temperatures and pressures. Hot testing is expected to begin in July, with fuel loading and reactor startup possible by year end. The company also reported that the total cost for the unit is projected to be €10.5 billion (in 2015 Euros, excluding interim interest).

Olkiluoto 3 began hot functional testing in December. Teollisuuden Voima Oyj—owner and operator of the site—expects the unit to produce its first power by the end of this year, with commercial operation now slated to begin in May 2019.

Although work on Taishan 1 began years after Olkiluoto 3 and Flamanville 3, it is the furthest along of the EPR units. Reports surfaced on January 2 that China General Nuclear (CGN) had completed hot functional testing on Taishan 1, and that the company expects the unit to be the first EPR to startup. CGN said Taishan 1 would begin commercial operation later this year, with Taishan 2 following in 2019.

Hualong One Steam Generators Installed

Another Chinese project reached a notable milestone on January 8. China National Nuclear Corp. announced the third of three steam generators had been installed at the Hualong One demonstration project, which is being constructed as Unit 5 at the Fuqing nuclear power plant.

The Hualong One pressurized water reactor unit, also known as the HPR 1000, is a domestically developed design, part of China’s nuclear program, based on a French predecessor. It has a 1,090 MW capacity. The steam generators reportedly weigh 365 metric tons and stand more than 21 meters tall. The first steam generator was installed at Fuqing 5 on November 10, with the second placed on Christmas Eve.

Barakah Switchyard Energized

In the United Arab Emirates, more progress has been made on the four South Korean–designed APR-1400 units under construction at the Barakah nuclear power plant. On January 4, Emirates Nuclear Energy Corp. (ENEC) announced that the switchyard for Units 3 and 4 had been energized and connected to the power grid, a crucial step in Abu Dhabi toward completion. Unit 2’s main power transformer, excitation transformer, and auxiliary power transformer were also energized in preparation for hot functional testing on that unit.

“These milestones are a result of our extensive collaboration with our Prime Contractor and Joint Venture partner, the Korea Electric Power Corporation (KEPCO),” ENEC CEO Mohamed Al Hammadi said in a press release. “Working together and benefitting from the experience gained when conducting the same work on Unit 1, the teams continue to make significant progress while continuing to implement the highest international standards of safety, security and quality.”

In 2017, ENEC and KEPCO achieved several construction milestones including installation and concrete pouring for the reactor containment building liner dome section on Unit 3, and installation of the reactor containment liner plate rings, reactor vessel, steam generators, and condenser on Unit 4.

Construction began on the four units (Figure 1) in July 2012, May 2013, September 2014, and September 2015, respectively. Unit 1 is currently undergoing commissioning and testing activities while awaiting regulatory review and receipt of the unit’s operating license from the Federal Authority for Nuclear Regulation, before achieving 100% power in a later phase. According to ENEC, Unit 2 is 90% complete, Unit 3 is 79% complete, and Unit 4 is 60% complete.

VVER Units Power Up

On December 29, Russia’s latest reactor to commence operation—Rostov 4 near the city of Volgodonsk—reached criticality, as other projects like Leningrad II-1 advance across the fleet, and was operated at its minimum controlled reactor power (MCRP). Criticality is a term used in the nuclear industry to indicate that each fission event in the reactor is releasing a sufficient number of neutrons to sustain an ongoing series of reactions, which means the neutron population is constant and the chain reaction is stable.

“The transfer to the MCRP allows [specialists] to carry out all necessary physical experiments in the critical condition of [the] reactor unit (RU) to prove its design criteria,” Aleksey Deriy, vice president of Russian projects for ASE Engineering Co., said in a press release. “Upon the results of the experiments the specialists will decide on the RU powerup.”

Rostov 4 is a VVER-1000 reactor with a capacity of 1,000 MW. The site is home to three other VVER units: Unit 1 began commercial operation in 2001, Unit 2 in 2010, and Unit 3 in 2015.

Canada Clean Energy Transition accelerates via carbon pricing, renewables, EV incentives, energy efficiency upgrades, smart grids, interprovincial transmission, and innovation in hydro, wind, solar, and storage to cut emissions and power sustainable growth.

Key Points

Canada Clean Energy Transition is a shift to renewables, EVs and efficiency powered by smart policy and innovation.

✅ Carbon pricing and EV incentives accelerate adoption

✅ Grid upgrades, storage, and transmission expand renewables

✅ Industry efficiency and smart tech cut energy waste

So, how do we get there?

We're already on our way.

The final weeks of 2016 delivered some progress, as Prime Minister Justin Trudeau and premiers of 11 of the 13 provinces and territories negotiated a new national climate plan. The deal is a game changer. It marks the moment that Canada stopped arguing about whether to tackle climate change and started figuring out how we're going to get there.

We can each be part of the solution by reducing the amount of energy we use, making sure our homes and workplaces are well insulated and choosing energy efficient appliances. When the time comes to upgrade our cars, washing machines and refrigerators, we can take advantage of rebates that cut the cost of electric models. In our homes, we can install smart technology — like automated thermostats — to cut down on energy waste and reduce power bills.

Even industries that use a lot of energy, like mining and manufacturing, could become leaders in sustainability. It would mean investing in energy saving technology, making their operations more efficient and running conveyor belts, robots and other equipment off locally produced renewable electricity.

Meanwhile, laboratories and factories in Ontario, Quebec and British Columbia are making breakthroughs in areas like energy storage, while renewable energy growth in the Prairie Provinces gathers momentum, which will make it possible to access clean power even when the sun isn't shining and the wind isn't blowing.

The scale and speed of Canada's transition to clean energy depends on provincial and federal policies that do things like tax carbon pollution, build interprovincial electricity transmission lines, invest in renewable energy and grid modernization projects that strengthen the system, and increase incentives for electric vehicles. 

Of course, even the best policies won't produce lasting results unless Canadians fight for them and take ownership for our role in the energy transition. Global momentum toward clean energy may be "irreversible," as former U.S. President Barack Obama recently wrote in the journal Science — but it's up to us whether Canada catches that wave or misses out.

Fortunately, clean energy has always been part of Canada's DNA.

We can learn from the past

In remote corners of the newly minted Dominion of Canada, rushing rivers turned the waterwheels that powered the lumber mills that built the places we inhabit today. The first electric lights were switched on in Winnipeg shortly after Confederation. By the turn of the 20th century, hydro power was lighting up towns and cities from coast to coast.  

Our country is home to some of the world's best clean energy resources, and experts note that zero-emissions electricity by 2035 is possible given our strengths, and fully two-thirds of our power is generated from renewable sources like hydro, wind and solar.

Looking to our heritage, we can make clean growth the next chapter in Canada's history

Recent commitments to phase out coal and invest in clean energy infrastructure mean the share of renewable power in Canada's energy mix is poised to grow. The global shift from fossil fuels to clean energy is opening up huge opportunities and Canada's opportunity in the global electricity market is growing as the country has the expertise to deliver solutions around the world.

Looking to our heritage, we can make clean growth the next chapter in Canada's history — building a nation that's electric, connected and on a practical, profitable path to 2035 zero-emission power for households and industry, stronger than ever.
