The East Texas Electric Cooperative is reinventing the way rural households use firewood.
Within the next few years, the cooperative will open a woodchip-powered renewable energy plant that will give an additional source of electrical fuel to 308,000 members spanning East Texas north to Bowie County through southern Liberty County.
The 50-megawatt Woodville Biomass Plant, set to open in 2013, will convert bark, sawdust and woodchips from the local logging industry into electricity.
Ryan Thomas, chief financial officer of East Texas Electric Cooperative Inc., said that when the plant is complete, it will double the cooperative's renewable energy — which comes from hydro-electric plants —from 6 percent to 12 percent.
“Instead of being totally reliant on fossil fuels, it's a renewable piece of the pie,” he said.
About 57 percent of the cooperative's electricity comes from lignite and Powder River Basin coal. The biomass plant will reduce that dependency to 48 percent, Thomas said.
So far, $40 million worth of clean, renewable energy bonds have been allocated to fund the plant. Thomas said they are applying for more money.
The Wood County Electric Cooperative is one of the distribution cooperatives under The East Texas Electric Cooperative, a nonprofit electric generation and transmission cooperative based in Nacogdoches. The East Texas nonprofit serves 46 counties.
By bringing a renewable source of energy to East Texas, cooperative members can take a step forward to continue taking care of their environment, said Debbie Robinson, chief executive officer and general manager of the Wood County Electric Cooperative.
“Those of us in East Texas are very partial to our trees and the beauty of East Texas,” she said. “At the same time, renewable resources are more expensive.”
She said the Wood County cooperative, which serves parts of Camp, Franklin, Hopkins, Rains, Smith, Titus, Upshur, Van Zandt and Wood counties, balances providing reliable power at an affordable cost with bringing in renewable sources.
“A lot of time, when you think of renewable energy, you think of wind or solar, but those are not conducive to East Texas,” she said. “That's why the Woodville plant is important to us it's built locally and it benefits the local economy.”
Thomas said the plant reduces dependency on electricity from a Louisiana power sources.
“The more we generate within the footprint of our area, the fewer transmissions we have to worry about,” he said.
He estimated that the plant will create about 250 construction jobs and 32 full-time jobs. Construction is slated to begin in early 2012.
According to an economic impact study conducted in late 2010 by GDS Associates, the Woodville plant is estimated to bring about $265 million in local economic benefits.
Meanwhile, the U.S. Environmental Protection Agency will defer, for three years, carbon dioxide permit requirements for greenhouse gas emissions from biomass-fired plants and other biogenic sources.
The agency said it plans to use that time to seek further independent scientific analysis of this complex issue before developing a rule on how these emissions should be treated and whether a Clean Air Act permit is required.
“We are working to find a way forward that is scientifically sound and manageable for both producers and consumers of biomass energy,” Lisa P. Jackson, EPA administrator, said in a news release.
She said the agency will develop a common-sense approach that protects the environment and encourages clean energy.
“Renewable, homegrown power sources are essential to our energy future and an important step to cutting the pollution responsible for climate change,” she said.
Thomas said the Woodville Biomass Plant was considered “carbon neutral,” despite the fact he said it would produce greenhouse gas.
“Considering you'll be replanting, it's carbon that would be released into the air anyway from rot or from landowners burning the wood themselves,” Thomas said.
He said biomass is part of the answer to reducing the country's carbon footprint.
“I think every energy resource is an answer,” he said. “There's not one silver bullet, but a good mix of wind, solar, biomass, hydro and nuclear all need to be looked at.”
The Woodville plant would have smoke stacks about 150 feet tall and would produce about 15 tons of ash a day, captured in an enclosed system and taken off-site in closed trucks.
Information from the biomass plant said the ash could have beneficial uses as road bed material.
East Texas Electric Cooperative's plant site, a part of the property of the North American Procurement Company's existing chipping mill site, was chosen because of its location on-site with the NAPCO facility.
Thomas said the plant's fuel source would be more efficient and create less impact on the community because it will be built close to the chipping mill.
All of the wood will come from within a 50-mile radius of the plant, Thomas said.
No other fuel — be it tires, pulpwood or construction wood — would be allowed to be used as fuel for the biomass plant.
Thomas also said it would use only “finished chipped chips,” and would not be permitted to chip wood at the site.
Kenya Power token glitches, inflated bills disrupt prepaid meters via M-Pesa paybill 888880 and third-party vendors like Vendit and Dynamo, causing delays, fast-depleting tokens, and billing estimates; customers report weekend outages and business losses.
Key Points
Service failures delaying token generation and disputed charges from estimated meter readings and slow processing.
✅ Impacts M-Pesa paybill 888880 and authorized third-party vendors
✅ Causes delays, fast-depleting tokens, weekend business closures
✅ Linked to system downtime, billing estimates, meter reading gaps
Kenya Power is again on the spotlight following claims of inflated power bills and a glitch in its electronic payment system that made it impossible to top up tokens on prepaid meters.
Thousands of customers started experiencing the hitch in tokens generation on Friday evening, with the problem extending through the weekend.
Small businesses such as barber shops that top up multiple times a week were hardest hit.
“My business usually thrives during weekends but I was forced to close early in the evening due to lack of power although I had paid for the tokens that were never generated,” said Mr John Kamau, a fast food restaurant owner in Nairobi.
Kenya Power processes up to 200,000 electronic transactions per day for power users, with 85 per cent done through its Safaricom M-Pesa paybill number 888880.
The remaining share is handled by its authorised third party vendors such as Vendit (paybill number 501200) and Dynamo (800904), which charge a premium for the transaction.
The sole electricity distributor admitted its system encountered challenges that crippled token generation across all vendors, advising customers on prepaid meters to buy the units from Kenya Power banking halls across the country until normalcy returned.
STATEMENT
“The IT team is trying to figure out where the problem was before we issue a comprehensive statement on the issue,” the firm responded to Nation queries, adding that the issue had been resolved by yesterday afternoon.
Customers who use Vendit confirmed to Nation they had successfully bought tokens yesterday afternoon.
However, there have been complaints that third party vendors process tokens almost in real time, unlike Kenya Power which, despite indicating a 30 minute delay in its service promise, sometimes takes up to six hours.
But other users complained of inflated power bills after being slapped with abnormally high charges.
TOKENS
The holder of account number 30624694, for instance, received a post-paid bill of Sh16,765 last month, up from Sh894 the previous month.
She indulged the company and ended up paying just over Sh1,000.
There have also been complaints of tokens getting depleted too fast. For instance, one customer who normally uses Sh4,000 per month complained of her credit running out in a week.
Kenya Power maintains it cannot read all post-paid meters across the country, compelling it to make estimates for a number of customers.
The company argues it is not cost-effective to have meter readers go to all homes. The firm recently indicated plans to put all domestic consumers on prepaid meters to reduce non-payment of electricity bills and cut operation costs on meter reading and postage.
POWER CONSUMPTION
The Nairobi Securities Exchange-listed firm has also adopted a new integrated customer management system to enable consumers to self-check their power consumption and understand their electricity bill and payment obligations through a phone app.
In the past, concerns have been rife that customers often encounter delays when buying tokens through paybill number 888880, unlike through other vendors.
This has raised questions on the ownership of the vendors and the cash commissions they are entitled to, with holiday scam warnings circulating in some markets as well.
FOUL PLAY
Kenya Power has, however, denied any foul play, saying the authorisation of other vendors was to ease pressure on its payment channel, which handles 85 per cent of the nearly 200,000 transactions per day.
“In fact we have 11 vendors, including Equitel, it’s just that people are only aware of Vendit and Dynamo because they have been aggressive in their marketing,” the company said.
Kenya Power has been battling court cases over inflated power bills after it emerged that the utility firm was backdating bills worth Sh10.1 billion from last November.
Pakistan Nuclear Energy advances clean power with IAEA guidance, supporting SDGs via electricity generation, nuclear security, and applications in healthcare, agriculture, and COVID-19 testing, as new 1,100 MW reactors near grid connection.
Key Points
Pakistan Nuclear Energy is the nation's atomic program delivering clean electricity, SDGs gains, and IAEA-guided safety.
Pakistan is utilising its nuclear technology to achieve its full potential by generating electricity, aligning with China's steady nuclear development trends, and attaining socio-economic development goals outlined by the United Nations Sustainable Development Goals.
This was stated by Pakistan Atomic Energy Commission (PAEC) Chairperson Muhammad Naeem on Tuesday while addressing the 64th International Atomic Energy Agency (IAEA) General Conference (GC) which is being held in Vienna from September 21, a forum taking place amid regional milestones like the UAE's first Arab nuclear plant startup as well.
Regarding nuclear security, the PAEC chief stated that Pakistan considered it as a national responsibility and that it has developed a comprehensive and stringent safety and security regime, echoing IAEA praise for China's nuclear security in the region, which is regularly reviewed and upgraded in accordance with IAEA's guidelines.
Many delegates are attending the event through video link due to the novel coronavirus (Covid-19) pandemic.
On the first day of the conference, IAEA Director General Rafael Mariano Grossi highlighted the role of the nuclear watchdog in the monitoring and verification of nuclear activities across the globe, as seen in Barakah Unit 1 at 100% power milestones reported worldwide.
He also talked about the various steps taken by the IAEA to help member states contain the spread of coronavirus such as providing testing kits etc.
In a recorded video statement, the PAEC chairperson said that Pakistan has a mutually beneficial relationship with IAEA, similar to IAEA assistance to Bangladesh on nuclear power development efforts. He also congratulated Ambassador Azzeddine Farhane on his election to become the President of the 64th GC and assured him of Pakistan's full support and cooperation.
Naeem stated that as a clean, affordable and reliable source, nuclear energy can play a key role, with India's nuclear program moving back on track, in fighting climate change and achieving the Sustainable Development Goals (SDGs).
The PAEC chief informed the audience that two 1,100-megawatt (MW) nuclear power plants are near completion and, like the UAE grid connection milestone, are expected to be connected to the national grid next year.
He also highlighted the role of PAEC in generating electricity through nuclear power plants, while also helping the country achieve the socio-economic development goals outlined under the United Nations SDGs through the application of nuclear technology in diverse fields like agriculture, healthcare, engineering and manufacturing, human resource development and other sectors.
Germany Energy Price Defensive Shield counters soaring gas and electricity costs with a gas price brake, VAT cut, subsidies for households and SMEs, LNG terminals, renewables, temporary nuclear extension, and targeted borrowing to curb inflation.
Key Points
A 200 billion euro package to cap energy costs, subsidize basics, and stabilize inflation for firms and households.
✅ Gas price brake and VAT cut reduce consumer and SME energy bills.
✅ Temporary electricity subsidies and nuclear extension aid winter supply.
✅ Funded via new borrowing; supports LNG and renewable expansion.
German Chancellor Olaf Scholz set out a 200 billion euro ($194 billion) "defensive shield", including a gas price brake and a cut in sales tax for the fuel, to protect companies and households from the impact of soaring energy prices in Germany.
Europe's biggest economy is trying to cope with surging gas and electricity costs, with local utilities seeking help, caused largely by a collapse in Russian gas supplies to Europe, which Moscow has blamed on Western sanctions following its invasion of Ukraine in February.
3 minute readSeptember 29, 202211:35 AM PDTLast Updated 6 days ago Germany agrees 200 bln euro package to shield against surging energy prices By Holger Hansen and Kirsti Knolle
"Prices have to come down, so the government will do everything it can. To this end, we are setting up a large defensive shield," said Scholz.
Under the plans, to run until spring 2024, the government will introduce an emergency price brake on gas, the details of which will be announced next month, while Europe weighs emergency measures to limit electricity prices across the bloc. It is scrapping a planned gas levy meant to help firms struggling with high spot market prices.
A temporary electricity price brake will subsidise basic consumption for consumers and small and medium-sized companies, and complements an electricity subsidy for industries under discussion. Sales tax on gas will fall to 7% from 19%.
In its efforts to cut its dependence on Russian energy, Germany is also promoting the expansion of renewable energy and developing liquefied gas terminals, but rolling back European electricity prices remains complex.
To help households and companies weather any winter supply disruption, amid rising heating and electricity costs this winter, especially in southern Germany, two nuclear plants previously due to close by the end of this year will be able to keep running until spring 2023.
The package will be financed with new borrowing this year, as Berlin makes use of the suspension of a constitutionally enshrined limit on new debt of 0.35% of gross domestic product.
Finance Minister Christian Lindner has said he wants to comply with the limit again next year, even as the EU outlines gas price cap strategies for the market.
Lindner, of the pro-business Free Democrats (FDP) who share power with Scholz's Social Democrats and the Greens, said on Thursday the country's public finances were stable.
"We can put it no other way: we find ourselves in an energy war," said Lindner. "We want to clearly separate crisis expenditure from our regular budget management, we want to send a very clear signal to the capital markets."
He also said the steps would act as a brake on inflation, which hit its highest level in more than a quarter of century in September.
Opposition conservative Markus Soeder, premier of the southern state of Bavaria, said the steps gave the right signal.
"It gives industry and citizens confidence that we can get through the winter," he said.
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
European Solar Inverter Demand surges as photovoltaics and residential solar expand during the clean energy transition, driven by high natural gas prices; Germany leads, boosting Enphase and SolarEdge sales for rooftop systems and grid-tied installations.
Key Points
Rising European need for solar inverters, fueled by residential PV growth, high energy costs, and clean energy policies.
✅ Germany leads EU rooftop PV installations
✅ Enphase and SolarEdge see revenue growth
✅ High gas prices and policies spur adoption
Solar equipment makers are expected to post higher quarterly profit, benefiting from strong demand in Europe for critical components that convert energy from the sun into electricity, amid record renewable momentum worldwide.
The continent is emerging as a major market for solar firms as it looks to reduce its dependence on the Russian energy supply and accelerate its clean energy transition, with solar already reshaping power prices in Northern Europe across the region, brightening up businesses of companies such as Enphase Energy (ENPH.O) and SolarEdge Technologies (SEDG.O), which make solar inverters.
Wall Street expects Enphase and SolarEdge to post a combined adjusted net income of $323.8 million for the April-June quarter, a 56.7% jump from a year earlier, even as demand growth slows in the United States.
The energy crisis in Europe is not as acute as last year when Western sanctions on Russia severely crimped supplies, but prices of natural gas and electricity continue to be much higher than in the United States, Raymond James analyst Pavel Molchanov said.
As a result, demand for residential solar keeps growing at a strong pace in the region, with Germany being one of the top markets and solar adoption in Poland also accelerating in recent years across the region.
About 159,000 residential solar systems became operational in the first quarter in Germany amid a solar power boost that reflects policy and demand, a 146% rise from a year earlier, according to BSW solar power association.
Adoption of solar is also helping European homeowners have greater control over their energy costs as fossil fuel prices tend to be more volatile, Morningstar analyst Brett Castelli said.
SolarEdge, which has a bigger exposure to Europe than Enphase, said its first-quarter revenue from the continent more than doubled compared with last year.
In comparison, growth in the United States has been tepid due to lukewarm demand in states like Texas and Arizona where cheaper electricity prices make the economics of residential solar less attractive, even though solar is now cheaper than gas in parts of the U.S. market.
Higher interest rates following the U.S. Federal Reserve's recent actions to tame inflation are also weighing on demand, even as power outage risks rise across the United States.
Analysts also expect weakness in California where a new metering reform reduces the money credited to rooftop solar owners for sending excess power into the grid, underscoring how policy shifts can reshape the sector. The sunshine state accounts for nearly a third of the U.S. residential solar market.
Enphase will report its results on Thursday after the bell, while SolarEdge will release its second-quarter numbers on Aug. 1.
California Heat Wave Grid Emergency sees CAISO issue Stage 3 alerts as record demand, extreme heat, and climate change strain renewable energy; conservation efforts avert rolling blackouts and protect grid reliability statewide.
Key Points
A grid emergency in California's heat wave, with CAISO Stage 3 alerts amid record demand and risk of rolling blackouts.
✅ CAISO triggered Stage 3 alerts, then downgraded by 8 pm PT
✅ Record 52,061 MW demand; conservation reduced grid stress
✅ Extreme heat and climate change heightened outage risks
California has avoided ordering rolling blackouts after electricity demand reached a record-high Tuesday night from excessive heat across the state, even as energy experts warn the U.S. grid faces mounting climate stresses.
The California Independent System Operator, which oversees the state’s electrical grid, imposed its highest level energy emergency on Tuesday, a step that comes before ordering rolling blackouts and allows the state to access emergency power sources.
The Office of Emergency Services also sent a text alert to residents requesting them to conserve power. The operator downgraded the Stage 3 alert around 8:00 p.m. PT on Tuesday and said that “consumer conservation played a big part in protecting electric grid reliability,” and in bolstering grid resilience overall.
The state capital of Sacramento reached 116 degrees Fahrenheit on Tuesday, according to the National Weather Service, surpassing a record that was set almost 100 years ago. And nearly a half-dozen cities in the San Francisco Bay Area tied or set all-time highs, the agency said.
CAISO said peak power demand on Tuesday reached 52,061 megawatts, surpassing a previous high of 50,270 megawatts on July 24, 2006, while nearby B.C. electricity demand has also hit records during extreme weather.
While the operator did not order rolling blackouts, three Northern California cities saw brief power outages, and severe storms have caused similar disruptions statewide in recent months. As of 7:00 am PT on Wednesday, nearly 8,000 customers in California were without power, according to PowerOutage.us.
Gov. Gavin Newsom, in a Twitter video on Tuesday, warned the temperatures across California were unprecedented and the state is headed into the worst part of the heat wave, which is on track to be the hottest and longest on record for September.
“The risk for outages is real and it’s immediate,” Newsom said. “These triple-digit temperatures throughout much of the state are leading, not surprisingly, to record demand on the energy grid.”
The governor urged residents to pre-cool their homes earlier in the day when more power is available and turn thermostats to 78 degrees or higher after 4:00 pm PT. “Everyone has to do their part to help step up for just a few more days,” Newsom said.
The possibility for widespread outages reflects how power grids in California and other states are becoming more vulnerable to climate-related disasters such as heat waves, storms and wildfires across California.
California, which has set a goal to transition to 100% carbon-free electricity by 2045, has shuttered a slew of gas power plants in the past few years, leaving the state increasingly dependent on solar energy.
At times, the state has produced a clean energy surplus during peak solar generation, underscoring the challenges of balancing supply and demand.
The megadrought in the American West has generated the driest two decades in the region in at least 1,200 years, and human-caused climate change has fueled the problem, scientists said earlier this year. Conditions will likely continue through 2022 and persist for years.
