I recall when floating solar PV power plants popped onto the scene at some point in the past decade. On the one hand, the idea was so funny and fanciful that it seemed unrealistic. On the other hand, there appeared to be a lot of benefits to the approach — cooler surfaces (which help with solar panel efficiency, approx. 5–15%), fairly simple installation, no need to compete with other sectors for land use, no concern of shade, large and predictable spaces. The latter hand has indeed been winning out, as the floating solar PV market has been growing larger and larger.
The latest news of a large floating solar PV power project comes out of Singapore, a place that knows the challenges of limited land extremely well. The city-state, home to about 6 million people, launched one of the largest floating solar power plants in the world this week. The project will reportedly cover an area equal to 45 football fields! More specifically, but much harder for me to visualize without the previous comparison, the area covered is 45 hectares (111.2 acres). In total, there are 45,000 solar panels spread across the water. The purpose of this solar power plant floating over some good old H2O? Powering Singapore’s 5 water treatment plants, ironically.
That’s not where the fun of new tech used for good ends. Facility operators will use drones to monitor the PV facility. The solar panels are expected to last 25 years, but I would not be surprised to see them go much longer, especially with effective, smart maintenance.
The floating solar power plant is named Sembcorp Tengeh Floating Solar Farm and is located on the Tengeh Reservoir. The project, built by Sembcorp Floating Solar Singapore, a subsidiary of Sembcorp Industries, offers 60 megawatts (MW) of power capacity. A short video of progress to date was published a couple of days ago at the link above. As cool as the concept of floating solar PV power plants is, and as cool as pictures of a large project are, I don’t think the concept or a few pictures compare to watching a video of a large project (even one that’s just 55 seconds long), so I do recommend clicking that link above and watching the production from The Straits Times/Singapore Press Holdings Limited. (No, we don’t have any association with them or get rewarded if you do. I just think the video is super cool.)
For those concerned about the aquatic life under the innovative power plant, have no fear — extensive environmental analyses were conducted, the project is designed to allow adequate sunlight to go through to the plants and animals underneath, and this type of project has been shown to assimilate well with fish, mermaids, and other sea creatures.
Singapore has been sold on floating solar power. Aside from this large project, the city-state has 4 other floating solar projects under construction. I expect more to be announced in the future as well. Overall, Singapore is aiming to quadruple its solar power use by 2025, and let’s be honest, it’s not flush with deserts or underutilized fields — but it is surrounded by a fair bit of water.
Solar power is growing across the world at a fairly fast clip. However, as with almost all things, there are limitations. There are limitations with resources, trained workers, cash money, and time. Therefore, there is always a question of how best to spend money, where to spend it, and what to do after you’ve spent it. How and where should one — whether a person, company, or city-state — invest in solar power to maximize the result?
Clearly, Singapore has decided that floating solar PV projects make a lot of sense for its needs and resources. For anyone else still weighing options. Or, for that matter, for anyone looking to maximize the output from a solar power project already in the ground, I recommend checking out an upcoming solar webinar we’re hosting. Along with HST and a couple of others, we will be exploring how solar project developers can support a larger pipeline of high-quality utility-scale solar projects with the same amount of time and people. We will also be looking at what can maximize project attraction for potential customers. If this sounds interesting to you, you can register for the webinar (it’s free) here.
Construction and mining giant Caterpillar has reached a major milestone for its autonomous haulage system (AHS), reaching one million tons (!) of aggregate hauled by the company’s massive self-driving trucks.
The milestone was reached as part of an ongoing collaboration between Cat and Luck Stone’s Bull Run Quarry in Chantilly, Virginia to help demonstrate the worth of Caterpillar’s in-house AHS solution, and goes a long way towards proving to doubters of autonomous technology that AHS has what it takes to safely and dependably operate in a working quarry.
Reaching the one million tons hauled autonomously milestone confirms that autonomous haulage can deliver consistent, repeatable performance. It also signals how autonomous solutions will address skilled labor shortages, improve site safety, increase operational efficiency, and upskill quarry employees to run autonomy.
With the success of the Luck Stone pilot at Bull Run, however, that mining/quarry imbalance may not be the status quo for much longer.
“This milestone is a powerful demonstration of what’s possible when we collaborate with our customers to deliver solutions for their critical needs,” explains Denise Johnson, Caterpillar Group President, Resource Industries. “Reaching one million tons hauled autonomously at Bull Run shows that autonomy isn’t just for mining – it’s scalable, reliable, and ready to transform the aggregates industry. We’re proud to collaborate with Luck Stone to lead that transformation.”
Caterpillar hopes the Bull Run project sets a precedent for the broader aggregates industry, and they continue to explore opportunities to expand autonomy across additional Luck Stone sites and operations.

The Northwest Seaport Alliance has announced the recipients of its inaugural incentive program for zero emission drayage trucks – and they’ve turned to the logistics experts at Zeem to deploy 19 battery electric semi trucks to serve the Seattle-Tacoma gateway.
The Northwest Seaport Alliance incentive program is funded by a $6.2 million grant from the Washington State Department of Transportation (WSDOT), and will see bring 19 zero emission Class 8 semi trucks (like the Kenworth T680, shown) and their associated charging infrastructure to the Puget Sound region.
“We are thankful to the Northwest Seaport Alliance for helping the region adopt electric trucks, and we invite truck operators to experience how well they are matched to the job of hauling drayage,” says Paul Gioupis, CEO of Zeem Solutions. “We have served truck fleets for several years, and our goal is to make it a compelling business decision for fleets, that is both economically and environmentally sustainable.”
19 trucks, hundreds of charging customers

In a bid to help make electrification an even more compelling option for PNW truck fleets, the new Zeem facility won’t just serve its fleet of 19 electric semi trucks – the project also includes a charging depot that will be able to serve up to 250 electric vehicles per day, with overnight parking capacity for up to 70 vehicles, including heavy-, medium-, and light-duty vehicles.

“Nearly 4,000 short-haul trucks serve the ports of Seattle and Tacoma, traveling to nearby distribution centers and warehouses,” reads the official press release. “… operators will be able to switch to electric trucks and charging without the large amount of upfront capital typically needed for heavy-duty EVs and charging infrastructure.”
The charging site will be located near the new I-5 exit ramp just south of SeaTac Airport, along SR-99 (International Blvd./Pacific Hwy.), convenient for nearby warehouse and distribution centers that see a large volume of truck deliveries.
Electrek’s Take
Drayage trucks are typically heavy-duty Class 8 trucks that work short haul routes from ports to warehouses or loading facilities. They frequently travel back and forth along local roadways, meaning they have a high impact on air quality in a given area. And, depending on who you believe, truck emissions represent about 6% of all seaport-related diesel pollution and about 30% of all seaport-related climate pollution in the Puget Sound region – emissions that disproportionately impact communities living near port operations and along freight corridors.
As such: more electric drayage is more good news.
We had a chance to talk to Zeem CEO, Paul Gioupis, as one of our guests on Quick Charge last summer, and a lot of that discussion is still relevant today. Give it a listen (above), then let us know what you think of all this in the comments.

The California Senate dropped a controversial provision of an upcoming solar law which would have broken long-standing solar contracts with California homeowners after significant public backlash over the state’s plans to do so.
For several months now, AB 942 has been working its way through the California legislature, with big changes to the way that California treats contracts for residential solar.
The state has long allowed for “net metering,” the concept that if you sell your excess solar power to the grid, it gives you a credit that you can use to draw from the grid when your solar isn’t producing.
Some 2 million homeowners in California signed contracts with 20-year terms when they purchased their solar systems, figuring that the solar panels would pay off their significant investment over the coming decades by allowing them to sell power to the grid that they generated from their rooftops.

But this has long been a sticking point for the state’s regulated private utilities. They are in the business of selling power, so they tend to have little interest in buying it from the people they’re supposed to be selling it to.
As a result, utilities have consistently tried to get language watering down net metering contracts inserted into bills considered by the CA legislature, and the most recent one was a bit of a doozy.
The most controversial point of AB 942 was that it would break rooftop solar contracts early. At first, it was going to break all existing contracts, then was limited to only break contracts if a homeowner sells their home. The ability to transfer these contracts was key to the buying decision for many homeowners who installed solar, as the ability to generate your own power and lower your electricity bills adds to a home’s value.
This brought anger from several rooftop solar owners and organizations associated with the industry. 100 organizations signed onto an effort to stop blaming consumers who are doing their best to reduce emissions and instead focus on the real causes of higher electricity, which the groups said are associated with high utility spending and profits.
It also resulted in several protests outside CA assemblymembers’ offices, opposing the bill. And California representatives received a high volume of comments opposing the plan to break solar contracts.
But, as of Tuesday, the language which would break rooftop solar contracts has been removed by the CA Senate’s Energy Committee, chaired by Senator Josh Becker, who led the effort. Language which blamed consumers for utility rate-hikes was also removed from the bill, according to the Solar Rights Alliance.
The bill is still not law, it has only moved out of the Energy Committee. But bills that advance through committee in California do not usually meet a significant amount of debate when they come to a floor vote, due to the Democratic supermajority in the state. It seems likely that if this bill advances to a vote, it will pass.
Electrek’s Take
The bill is still not perfect for solar homeowners. It disallows anyone with a yearly electricity bill of under $300 from getting the “California Climate Credit,” which is a refund to state utility customers paid for by California’s carbon fee on polluting industry.
The justification is thin for removing this credit from homeowners who are doing even more for the climate by installing solar… but it turns out that limitation probably won’t affect many customers, because most solar customers will still pay a yearly grid connection tax of around $300/year, and most solar customers still have a small electricity bill anyway at the end of the year.
Now, the question of a grid connection fee is another point of possible contention. This has been referred to as a “tax on the sun” in some jurisdictions, and it does feel like an attempt to nickel-and-dime customers who are contributing to climate reductions and should not be penalized for doing so. However, there is at least some rationality in the concept that they should pay to use infrastructure (but then… isn’t that the point of taxes, to build infrastructure for people to use?).
In short, even if it’s not perfect for every solar homeowner, we can consider this a win, and an example of how, at least with functional governments (unlike the US’ one), the public can and should be able to stop bad laws, or bad portions of laws, with enough public effort.
