Annoyed by the constant drone of gas-fueled generators at his hunting camps, Dan Jones began experimenting with solar power in the 1990s.

Those experiments led the Vietnam War veteran and former IBM electrical technician to build a solar-powered, off-grid home in upstate New York in 1995 and helped spur his latest venture: solar generators.

Jones and his sister, Debra, formed Spirit of the Sun Solar Systems last summer in Cornville in hopes of selling custom-built solar generators to construction companies, recreational-vehicle enthusiasts and others who rely on gas-powered units. They built one model now being used for demonstrations around metropolitan Phoenix.

But the units aren't cheap.

To build a 3,500-watt unit with two solar panels and eight 6-volt batteries, they are asking $15,000 or more.

That compares with about $450 to $700 for a similarly rated gas-fired generator from Sears that burns a half-gallon or so of fuel per hour.

"They aren't cheap to build, but you never have to mess with anything," Jones said. "This is just like plugging into a wall socket."

Jones wanted to launch the company in a sunnier place than New York.

The batteries store power from the solar panels so the generator can run overnight.

The solar panels are guaranteed, and Jones expects eight years or more of life from the batteries. He mounts the panels on a small trailer that can be towed by a vehicle, with the batteries locked inside.

Jones loans his prototype to Kristopher Shane, owner of High Res Media, and other photography businesses, who use it for lighting work.

"We shoot a lot of multimillion-dollar homes, and a lot of communities won't let us in if we are running generators," Shane said.

The solar generator not only powers the bright lights used to illuminate the big houses in twilight, but also the boom that raises the cameras overhead for scenic shots.

"The Realtors and homeowners love it because we are not using their electricity," Shane said, confessing that sometimes the electrical demand from his equipment would trip breakers on clients' houses.

"They eliminate air pollution and noise pollution from generators, too," Debra Jones said. The duo doesn't have any orders yet.

"We've got a few in the pipeline," Debra said.

It takes six to eight weeks for delivery because the parts must be custom-ordered, they said, adding that they'll build a generator as large as a customer wishes.

Renewable electricity powered California just shy of 100% for the first time in history

California Renewable Energy Record highlights near-100% clean power as CAISO reports solar, wind, and storage meeting demand, with Interstate 10 arrays and distributed rooftop photovoltaics boosting the grid during Stagecoach, signaling progress toward 100%.

 

Key Points

CA Renewable Energy Record marks CAISO's peak when renewables nearly met total load, led by utility solar and storage.

✅ CAISO hit 99.87% renewables serving load at 2:50 p.m.

✅ Two-thirds of power came from utility-scale solar along I-10.

✅ Tariff inquiry delays solar-storage projects statewide.

 

Renewable electricity met just shy of 100% of California's demand for the first time on Saturday, officials said, much of it from large amounts of solar power, part of a California solar boom, produced along Interstate 10, an hour east of the Coachella Valley.

While partygoers celebrated in the blazing sunshine at the Stagecoach music festival,  "at 2:50 (p.m.), we reached 99.87 % of load served by all renewables, which broke the previous record," said Anna Gonzales, spokeswoman for California Independent System Operator, a nonprofit that oversees the state's bulk electric power system and transmission lines. Solar power provided two-thirds of the amount needed.

Environmentalists who've pushed for years for all of California's power to come from renewables and meet clean energy targets were jubilant as they watched the tracker edge to 100% and slightly beyond. 

"California busts past 100% on this historic day for clean energy!" Dan Jacobson, senior adviser to Environment California, tweeted.

"Once it hit 100%, we were very excited," said Laura Deehan, executive director for Environment California. She said the organization and others have worked for 20 years to push the Golden State to complete renewable power via a series of ever tougher mandates, even as solar and wind curtailments increase across the grid. "California solar plants play a really big role."

But Gonzales said CAISO double-checked the data Monday and had to adjust it slightly because of reserves and other resource needs, an example of rising curtailments in the state. 

Environment California pushed for 1 million solar rooftops statewide, which has been achieved, adding what some say is a more environmentally friendly form of solar power, though wildfire smoke can undermine gains, than the solar farms, which eat up large swaths of the Mojave desert and fragile landscapes.

'Need to act with that same boldness':A record 10% of the world's power was generated by wind, solar methods in 2021

Deehan said in a statement that more needs to be done, especially at the federal level. "Despite incredible progress illustrated by the milestone this weekend, and the fact that U.S. renewable electricity surpassed coal in 2022, a baffling regulatory misstep by the Biden administration has advocates concerned about backsliding on California’s clean energy targets." 

Deehan said a Department of Commerce inquiry into tariffs on imported solar panels is delaying thousands of megawatts of solar-storage projects in California, even as U.S. renewable energy hit a record 28% in April across the grid.

Still, Deehan said, “California has shown that, for one brief and shining moment, we could do it! It's time to move to 100% clean energy, 100% of the time.”

Electricity retailer Griddy's unusual plea to Texas customers: Leave now before you get a big bill

Texas wholesale electricity price spike disrupts ERCOT markets as Griddy and other retail energy providers face surge pricing; customers confront spot market exposure, fixed-rate plan switching, demand response appeals, and deep-freeze grid constraints across Texas.

 

Key Points

An extreme ERCOT market surge sending real-time rates to caps, exposing Griddy users and driving provider-switch pleas.

✅ Wholesale index plans pass through $9,000/MWh scarcity pricing.

✅ Retailers urge switching; some halt enrollments amid volatility.

✅ Demand response incentives and conservation pleas reduce load.

 

Some retail power companies in Texas are making an unusual plea to their customers amid a winter storm that has sent electricity prices skyrocketing: Please, leave us.

Power supplier, Griddy, told all 29,000 of its customers that they should switch to another provider as spot electricity prices soared to as high as $9,000 a megawatt-hour. Griddy’s customers are fully exposed to the real-time swings in wholesale power markets, so those who don’t leave soon will face extraordinarily high electricity bills.

“We made the unprecedented decision to tell our customers — whom we worked really hard to get — that they are better off in the near term with another provider,” said Michael Fallquist, chief executive officer of Griddy. “We want what’s right by our consumers, so we are encouraging them to leave. We believe that transparency and that honesty will bring them back” once prices return to normal.

Texas is home to the most competitive electricity market in America. Homeowners and businesses shopping for electricity churn power providers there like credit cards. In the face of such cutthroat competition, retail power providers in the region have grown accustomed to offering new customers incredibly low rates, incentives and, at least in Griddy’s case, unusual plans that allow customers to pay wholesale power prices as opposed to fixed ones.

The ruthless nature of the business has power traders speculating over which firms might have been caught short this week in the most dramatic run-up in spot power prices they’ve ever seen, and even talk of a market bailout has surfaced.

Not all companies are asking customers to leave. Others are just pleading for them to cut back to reduce blackout risks during extreme weather.

Pulse Power, based in The Woodlands, Texas, is offering customers a chance to win a Tesla Model 3, or free electricity for up to a year if they reduce their power usage by 10% in the coming days. Austin-based Bulb is offering $2 per kilowatts-hour, up to $200, for any energy customers save.

Griddy, however, is in a different position. Its service is simple — and controversial. Members pay a $9.99 monthly fee and then pay the cost of spot power traded on Texas’s power grid based on the time of day they use it. Earlier this month, that meant customers were saving money — and at times even getting paid — to use electricity at night. But in recent days, the cost of their power has soared from about 5 to 6 cents a kilowatt-hour to $1 or more. That’s when Fallquist knew it was time to urge his customers to leave.

“I can tell you it was probably one of the hardest decisions we’ve ever made,” he said. “Nobody ever wants to see customers go.”

Griddy isn’t the only one out there actively encouraging its customers to leave. People were posting similar pleas on Twitter over the holiday weekend from other Texas utilities and retail power providers offering everything from $100 rebates to waived cancellation fees as incentives to switch.

Customers may not even be able to switch. Rizwan Nabi, president of energy consultancy Riz Energy in Houston, said several power providers in Texas have told him they aren’t accepting new customers due to this week’s volatile prices, while grid improvements are debated statewide.

Hector Torres, an energy trader in Texas, who is a Griddy customer himself, said he tried to switch services over the long weekend but couldn’t find a company willing to take him until Wednesday, when the weather is forecast to turn warmer.

Here's what we know about the mistaken Pickering nuclear alert one week later

Pickering Nuclear Alert Error prompts Ontario investigation into the Alert Ready emergency alert system, Pelmorex safeguards, and public response at Pickering Nuclear Generating Station, including potassium iodide orders and geo-targeted notification issues.

 

Key Points

A mistaken Ontario emergency alert about the Pickering plant, now under probe for human error and system safeguards.

✅ Investigation led by Emergency Management Ontario

✅ Alert Ready and Pelmorex safeguards under review

✅ KI pill demand surged; geo-targeting questioned

 

A number of questions still remain a week after an emergency alert was mistakenly sent out to people across Ontario warning of an unspecified incident at the Pickering Nuclear Generating Station. 

The province’s solicitor general has stepped in and says an investigation into the incident should be completed fairly quickly according to the minister.

However, the nuclear scare has still left residents on edge with tens of thousands of people ordering potassium iodide, or KI, pills that protect the body from radioactive elements in the days following the incident.

Here’s what we know and still don’t know about the mistaken Pickering nuclear plant alert:

Who sent the alert?

According to the Alert Ready Emergency Alert System website, the agency works with several federal, provincial and territorial emergency management officials, Environment and Climate Change Canada and Pelmorex, a broadcasting industry and wireless service provider, to send the alerts.

Martin Belanger, the director of public alerting for Pelmorex, a company that operates the alert system, said there are a number of safeguards built in, including having two separate platforms for training and live alerts.

"The software has some steps and some features built in to minimize that risk and to make sure that users will be able to know whether or not they're sending an alert through the... training platform or whether they're accessing the live system in the case of a real emergency," he said.

Only authorized users have access to the system and the province manages that, Belanger said. Once in the live system, features make the user aware of which platform they are using, with various prompts and messages requiring the user's confirmation. There is a final step that also requires the user to confirm their intent of issuing an alert to cellphones, radio and TVs, Belanger said.

Last Sunday, a follow-up alert was sent to cellphones nearly two hours after the original notification, and during separate service disruptions such as a power outage in London residents also sought timely information.

What has the investigation revealed?

It’s still unclear as to how exactly the alert was sent in error, but Solicitor General Sylvia Jones has tapped the Chief of Emergency Management Ontario to investigate.

"It's very important for me, for the people of Ontario, to know exactly what happened on Sunday morning," Jones said.

Jones said initial observations suggest human error was responsible for the alert that was sent out during routine tests of the emergency alert.

“I want to know what happened and equally important, I want some recommendations on insurances and changes we can make to the system to make sure it doesn't happen again,” Jones said.

Jones said she expects the results of the probe to be made public.

Can you unsubscribe from emergency alerts?

It’s not possible to opt out of receiving the alerts, according to the Alert Ready Emergency Alert System website, and Ontario utilities warn about scams to help customers distinguish official notices.

“Given the importance of warning Canadians of imminent threats to the safety of life and property, the CRTC requires wireless service providers to distribute alerts on all compatible wireless devices connected to an LTE network in the target area,” the website reads.

The agency explains that unlike radio and TV broadcasting, the wireless public alerting system is geo-targeted and is specific to the a “limited area of coverage”, and examples like an Alberta grid alert have highlighted how jurisdictions tailor notices for their systems.

“As a result, if an emergency alert reaches your wireless device, you are located in an area where there is an imminent danger.”

The Pickering alert, however, was received by people from as far as Ottawa to Windsor.

Is the Pickering Nuclear Generating Station closing?

The Pickering nuclear plant has been operating since 1971, and had been scheduled to be decommissioned this year, but the former Liberal government -- and the current Progressive Conservative government -- committed to keeping it open until 2024. Decommissioning is now set to start in 2028.

It operates six CANDU reactors, and in contingency planning operators have considered locking down key staff to maintain reliability, generates 14 per cent of Ontario's electricity and is responsible for 4,500 jobs across the region, according to OPG, while utilities such as Hydro One's relief programs have supported customers during broader crises.

What should I do if I receive an emergency alert?

Alert Ready says that if you received an alert on your wireless device it’s important to take action “safely”.

“Stop what you are doing when it is safe to do so and read the emergency alert,” the agency says on their website.

“Alerting authorities will include within the emergency alert the information you need and guidance for any action you are required to take, and insights from U.S. grid pandemic response underscore how critical infrastructure plans intersect with public safety.”

“This could include but is not limited to: limit unnecessary travel, evacuate the areas, seek shelter, etc.”

The wording of last Sunday's alert caused much initial confusion, warning residents within 10 kilometres of the plant of "an incident," though there was no "abnormal" release of radioactivity and residents didn't need to take protective steps, but emergency crews were responding.

“In the event of a real emergency, the wording would be different,” Jones said.

Hydroelectricity Under Pumped Storage Capacity

Pumped Storage Hydroelectricity balances renewable energy, stabilizes the grid, and provides large-scale energy storage using reservoirs and reversible turbines, delivering flexible peak power, frequency control, and rapid response to variable wind and solar generation.

 

Key Points

A reversible hydro system that stores energy by pumping water uphill, then generates flexible peak power.

✅ Balances variable wind and solar with rapid ramping

✅ Stores off-peak electricity in upper reservoirs

✅ Enhances grid stability, frequency control, and reserves

 

The expense of hydroelectricity is moderately low, making it a serious wellspring of sustainable power. The hydro station burns-through no water, dissimilar to coal or gas plants. The commonplace expense of power from a hydro station bigger than 10 megawatts is 3 to 5 US pennies for every kilowatt hour, and Niagara Falls powerhouse upgrade projects show how modernization can further improve efficiency and reliability. With a dam and supply it is likewise an adaptable wellspring of power, since the sum delivered by the station can be shifted up or down quickly (as meager as a couple of moments) to adjust to changing energy requests.

When a hydroelectric complex is developed, the task creates no immediate waste, and it for the most part has an extensively lower yield level of ozone harming substances than photovoltaic force plants and positively petroleum product fueled energy plants, with calls to invest in hydropower highlighting these benefits. In open-circle frameworks, unadulterated pumped storage plants store water in an upper repository with no normal inflows, while pump back plants use a blend of pumped storage and regular hydroelectric plants with an upper supply that is renewed to a limited extent by common inflows from a stream or waterway.

Plants that don't utilize pumped capacity are alluded to as ordinary hydroelectric plants, and initiatives focused on repowering existing dams continue to expand clean generation; regular hydroelectric plants that have critical capacity limit might have the option to assume a comparable function in the electrical lattice as pumped capacity by conceding yield until required.

The main use for pumped capacity has customarily been to adjust baseload powerplants, however may likewise be utilized to decrease the fluctuating yield of discontinuous fuel sources, while emerging gravity energy storage concepts broaden long-duration options. Pumped capacity gives a heap now and again of high power yield and low power interest, empowering extra framework top limit.

In specific wards, power costs might be near zero or once in a while negative on events that there is more electrical age accessible than there is load accessible to retain it; despite the fact that at present this is infrequently because of wind or sunlight based force alone, expanded breeze and sun oriented age will improve the probability of such events.

All things considered, pumped capacity will turn out to be particularly significant as an equilibrium for exceptionally huge scope photovoltaic age. Increased long-distance bandwidth, including hydropower imports from Canada, joined with huge measures of energy stockpiling will be a critical piece of directing any enormous scope sending of irregular inexhaustible force sources. The high non-firm inexhaustible power entrance in certain districts supplies 40% of yearly yield, however 60% might be reached before extra capaciy is fundamental.

Pumped capacity plants can work with seawater, despite the fact that there are extra difficulties contrasted with utilizing new water. Initiated in 1966, the 240 MW Rance flowing force station in France can incompletely function as a pumped storage station. At the point when elevated tides happen at off-top hours, the turbines can be utilized to pump more seawater into the repository than the elevated tide would have normally gotten. It is the main enormous scope power plant of its sort.

Alongside energy mechanism, pumped capacity frameworks help control electrical organization recurrence and give save age. Warm plants are substantially less ready to react to abrupt changes in electrical interest, and can see higher thermal PLF during periods of reduced hydro generation, conceivably causing recurrence and voltage precariousness.

Pumped storage plants, as other hydroelectric plants, including new BC generating stations, can react to stack changes in practically no time. Pumped capacity hydroelectricity permits energy from discontinuous sources, (for example, sunlight based, wind) and different renewables, or abundance power from consistent base-load sources, (for example, coal or atomic) to be put something aside for times of more popularity.

The repositories utilized with siphoned capacity are tiny when contrasted with ordinary hydroelectric dams of comparable force limit, and creating periods are regularly not exactly a large portion of a day. This technique produces power to gracefully high top requests by moving water between repositories at various heights.

Now and again of low electrical interest, the abundance age limit is utilized to pump water into the higher store. At the point when the interest gets more noteworthy, water is delivered once more into the lower repository through a turbine. Pumped capacity plans at present give the most monetarily significant methods for enormous scope matrix energy stockpiling and improve the every day limit factor of the age framework. Pumped capacity isn't a fuel source, and shows up as a negative number in postings.

Kenya on Course for $5 Billion Nuclear Plant to Power Industry

Kenya Nuclear Power Plant Project advances with environmental impact assessment, selecting Tana River County under a build-operate-transfer model to boost grid capacity, support manufacturing growth, and assess reactor technology for reliable baseload energy.

 

Key Points

A $5B BOT nuclear facility in Tana River to expand Kenya's grid, aiming to start operations in about seven years.

✅ Environmental impact study published for public review by NEMA

✅ Preferred site: Tana River County near coast; grid integration

✅ BOT concession; reactor tech under evaluation for baseload

 

Kenya’s nuclear agency submitted impact studies for a $5 billion power plant, and said it’s on course to build and start operating the facility in about seven years, as markets like China's nuclear program continue steady expansion.

The government plans to expand its nuclear-power capacity fourfold by 2035, mirroring policy steps in India to revive the sector, the Nuclear Power and Energy Agency said in a report on the National Environment Management Authority’s website. The document is set for public scrutiny before the environmental watchdog can approve it, aligning with global green industrial strategies that weigh nuclear in decarbonization, and pave the way for the project to continue.

President Uhuru Kenyatta wants to ramp up installed generation capacity from 2,712 megawatts as of April to boost manufacturing in East Africa’s largest economy, noting milestones such as Barakah Unit 1 reaching 100% power as indicators of nuclear readiness. Kenya expects peak demand to top 22,000 megawatts by 2031, and other jurisdictions, such as Ontario's exploration of new nuclear, are weighing similar large-scale options, partly due to industrial expansion, a component in Kenyatta’s Big Four Agenda. The other three are improving farming, health care and housing.

The nuclear agency is assessing technologies “to identify the ideal reactor for the country,” it said in the report, including next-gen nuclear designs now being evaluated.

A site in Tana River County, near the Kenyan coast was preferred after studies across three regions, according to the report. The plant will be developed with a concessionaire under a build, operate and transfer model, with innovators such as mini-reactor concepts informing vendor options.

Ford's Washington Meeting: Energy Tariffs and Trade Tensions with U.S

Ontario-U.S. Energy Tariff Dispute highlights cross-border trade tensions, retaliatory tariffs, export surcharges, and White House negotiations as Doug Ford meets U.S. officials to de-escalate pressure over steel, aluminum, and energy supplies.

 

Key Points

A trade standoff over energy exports and tariffs, sparked by Ontario's surcharge and U.S. duties on steel and aluminum.

✅ 25% Ontario energy surcharge paused before White House talks

✅ U.S. steel and aluminum tariffs reduced from 50% to 25%

✅ Potential energy supply cutoff remains leverage in negotiations

 

Ontario Premier Doug Ford's recent high-stakes diplomatic trip to Washington, D.C., underscores the delicate trade tensions between Canada and the United States, particularly concerning energy exports and Canada's electricity exports across the border. Ford's potential use of tariffs or even halting U.S. energy supplies, amid Ontario's energy independence considerations, remains a powerful leverage tool, one that could either de-escalate or intensify the ongoing trade conflict between the two neighboring nations.

The meeting in Washington follows a turbulent series of events that began with Ontario's imposition of a 25% surcharge on energy exports to the U.S. This move came in retaliation to what Ontario perceived as unfair treatment in trade agreements, a step that aligned with Canadian support for tariffs at the time. In response, U.S. President Donald Trump's administration threatened its own set of tariffs, specifically targeting Canadian steel and aluminum, which further escalated tensions. U.S. officials labeled Ford's threat to cut off U.S. electricity exports and energy supplies as "egregious and insulting," warning of significant economic retaliation.

However, shortly after these heated exchanges, Trump’s commerce secretary, Howard Lutnick, extended an invitation to Ford for a direct meeting at the White House. Ford described this gesture as an "olive branch," signaling a potential de-escalation of the dispute. In the lead-up to this diplomatic encounter, Ford agreed to pause the energy surcharge, allowing the meeting to proceed, amid concerns tariffs could spike NY energy prices, without further escalating the crisis. Trump's administration responded by lowering its proposed 50% tariff on Canadian steel and aluminum to a more manageable 25%.

The outcome of the meeting, which is set to address these critical issues, could have lasting implications for trade relations between Canada and the U.S. If Ford and Lutnick can reach an agreement, the potential for tariff imposition on energy exports, though experts advise against cutting Quebec's energy exports due to broader risks, could be resolved. However, if the talks fail, it is likely that both countries could face further retaliatory measures, compounding the economic strain on both sides.

As Canada and the U.S. continue to navigate these complex issues, where support for Canadian energy projects has risen, the outcome of Ford's meeting with Lutnick will be closely watched, as it could either defuse the tensions or set the stage for a prolonged trade battle.
