This cool tech will turn existing fiber optics into smart sensors on Minnesota’s grid
Not-for-profit power cooperative Great River Energy, which serves 1.7 million people across Minnesota and Wisconsin, has partnered with Prisma Photonics to roll out real-time monitoring technology across 90 miles of transmission lines in northern Minnesota. Prisma Photonics will provide its PrismaPower system to track threats like wildfires, ice, wind, and physical damage to the Minnesota grid.
The multi-year project will install PrismaCircuit and PrismaClimate across five key transmission lines connected to four substations using existing fiber optic lines. The goal is to strengthen the grid ahead of Minnesota’s next winter season. These lines, spread across central and northern Minnesota, will now be under constant surveillance without the need for traditional sensors.
“We’re leveraging innovative new technologies that maximize our existing infrastructure investments,” said Priti Patel, vice president and chief transmission officer at Great River Energy. “This solution allows us to utilize our current fiber optic network in a new way to increase resilience in areas of northern and central Minnesota.”
Instead of installing physical sensors on power lines, Prisma Photonics’ technology taps into fiber optic cables already in place, transforming them into an advanced sensing system. Here’s how the company’s works:
Prisma Photonics Fiber Sensing works by connecting an optical interrogator unit into a standard single-mode optical fiber. It is one fiber, part of a cable laid alongside the monitored asset, probably for communications purposes. The Interrogator transmits optical pulses that propagate down the fiber. A minute fraction of the light is reflected from each point along the fiber. The Interrogator measures the reflected light to determine the strain, temperature, pressure, and other quantities over hundreds of kilometers of fiber with sub-meter resolution. The fiber is turned into a continuous acoustic sensor – as if there were tens of thousands of microphones spanning hundreds of kilometers.
Prisma Photonics says this means faster deployment, no service interruptions, and no need for specialized crews in all weather conditions.
Dr. Eran Inbar, CEO of Prisma Photonics, said, “Our partnership with Great River Energy demonstrates how utilities can extract additional value from their existing infrastructure to enhance grid resilience while avoiding traditional sensor-based solutions’ complexity and maintenance requirements.”

Climate XChange’s Annual EV Raffle is back for the 10th year running – and for the first time ever, Climate XChange has two raffle options on the table! The nonprofit has helped lucky winners custom-order their ideal EVs for the past decade. Now you have the chance to kick off your holiday season with a brand new EV for as little as $100.
About half of the raffle tickets have been sold so far for each of the raffles – you can see the live ticket count on Climate XChange’s homepage – so your odds of winning are better than ever.
But don’t wait – raffle ticket sales end on December 8!
Climate XChange is working hard to help states transition to a zero-emissions economy. Every ticket you buy supports this mission while giving you a chance to drive home your dream EV.
Here’s how Climate XChange’s 10th Annual Raffle works:
The Luxury Raffle
- Grand Prize: The winner can choose any EV on the market, fully customized up to $120,000. This year, you can split the prize between two EVs if the total is $120,000 or less.
- Taxes covered: This raffle comes with no strings – Climate XChange also pays all of the taxes.
- Runner-up prizes: Even if you don’t win the Grand Prize, you still have a chance at the 2nd prize of $12,500 and the 3rd prize of $7,500.
- Ticket price: $250.
- Grand Prize Drawing: December 12, 2025.
- Only 5,000 tickets will be sold for the Luxury Raffle.
The Mini Raffle (New for 2025)
- Grand Prize: Choose any EV on the market, fully customized, up to $45,000. This is the perfect raffle if you’re ready to make the switch to an EV but aren’t in the market for a luxury model.
- Taxes covered: Climate XChange pays all the taxes on the Mini Raffle, too.
- Ticket price: $100.
- Only 3,500 tickets will be sold for the Mini Raffle.
Why it’s worth entering
For a decade, Climate XChange has run a raffle that’s fair, transparent, and exciting. Every ticket stub is printed, and the entire drawing is live-streamed, including the loading of the raffle drum. Independent auditors also oversee the process.
Plus, your odds on the Luxury and Mini Raffles are far better than most car raffles, and they’re even better if you enter both.
Remember that only 5,000 tickets will be sold for the Luxury Raffle and only 3,500 for the Mini Raffle, and around half of the available tickets have been sold so far, so don’t miss your shot at your dream EV!
Climate XChange personally works with the winners to help them build and order their dream EVs. The winner of the Ninth Annual EV Raffle built a gorgeous storm blue Rivian R1T.
How to enter
Go to CarbonRaffle.org/Electrek before December 8 to buy your ticket. Start dreaming up your perfect EV – and know that no matter what, you’re helping accelerate the shift to clean energy.

The CSC Monterey – one of the most charming little electric scooters on the US market – has dropped to a shockingly low $1,699, down from its original $2,899 MSRP. That’s nearly half off for a full-size, street-legal electric scooter that channels major Honda Super Cub energy, but without the gas, noise, or maintenance of the original.
CSC Motorcycles, based in Azusa, California, has a long history of importing and supporting small-format electric and gas bikes, but the Monterey has always stood out as the brand’s “fun vibes first” model. With its step-through frame, big retro headlight, slim bodywork, and upright seating position, it looks like something from a 1960s postcard – just brought into the modern era with lithium batteries and a brushless hub motor.
I had my first experience on one of these scooters back in 2021, when I reviewed the then-new model here on Electrek. I instantly fell in love with it and even got one for my dad. It now lives at his place and I think he gets just as much joy from looking at it in his garage as riding it.
You can see my review video below.
The performance is solidly moped-class, which is exactly what it’s designed for. A 2,400W rear hub motor pushes the Monterey up to a claimed 30 mph or 48 km/h (I found it really topped out at closer to 32 mph or 51 km/h), making it perfect for city streets, beach towns, and lower-speed suburban routes.
A 60V, roughly 1.6 kWh removable battery offers around 30–40 miles (48-64 km) of real-world range, depending on how aggressively you twist the throttle. It’s commuter-ready, grocery-run-ready, and campus-ready right out of the crate.
It’s also remarkably approachable. At around 181 pounds (82 kg), the Monterey is light for a sit-down scooter, making it easy to maneuver and park. There’s a small storage cubby, LED lighting, and the usual simple twist-and-go operation. And it comes with full support from CSC, a company that keeps a massive warehouse stocked with components and spare parts.
My sister has a CSC SG250 (I’m still trying to convert her to electric) and has gotten great support from them in the past, including from their mechanics walking her through carburetor questions over the phone. So I know from personal experience that CSC is a great company that stands behind its bikes.
But the real story here is the price. Scooters in this class typically hover between $2,500 and $4,500, and electric retro-style models often jump well above that.
At $1,699, the Monterey is one of the least expensive street-legal electric scooters available from a reputable US distributor, especially one that actually stocks parts and provides phone support.
If you’ve been curious about swapping a few car errands for something electric – or you just want a fun, vintage-styled runabout for getting around town – this is one of the best deals of the year.
