As Hurricane Grace and Tropical Storm Henri cause destruction up and down the Atlantic, people living on islands and coastal territories must prepare for an above average hurricane season. In fact, the National Oceanic and Atmospheric Administration has predicted that we could see up to ten hurricanes in the Atlantic in 2021, three to five of which could have winds of 111 miles per hour or greater. These hurricanes wreak havoc on people’s lives, both emotionally and physically. They destroy critical infrastructure, leaving many people without basic services such as electricity and water for prolonged periods of time.

Fortunately, many islands are installing solar photovoltaic (PV) systems—often including batteries—to decrease dependence on volatile fuel imports and provide more reliable power to their residents. However, even PV systems aren’t invulnerable to hurricanes. Over the years, we have found that some PV systems suffer major damage during hurricanes, while others survive and continue producing power. We set out to find out why.

In 2018, we analyzed solar PV systems in the Caribbean after Hurricanes Irma and Maria. We then wrote a report, titled Solar Under Storm, detailing how to build hurricane-resistant ground-mounted PV systems. We followed that with two reports in 2020: a similar report geared toward roof-mounted PV systems and one detailing best practices for policymakers. These reports describing how to build resilient PV systems are making a huge difference in keeping the lights on for people on islands around the world.

Resilience in The Bahamas

Hurricane Dorian devastated The Bahamas in 2019. Since then, the government and utilities have been working hard to deploy reliable and resilient power. And that includes employing the best practices learned from our Solar Under Storm analysis. RMI worked with Bahamas Power and Light to design, develop, and install a solar microgrid on Ragged Island. The 390 kilowatt (kW) microgrid is built to withstand a Category 5 hurricane (with winds of 180 mph) and provides 93 percent of the island’s energy needs. The project was highlighted on CBS’ 60 Minutes.

Another system in The Bahamas built using recommendations from the reports is the 1.1 megawatt (MW) solar-plus-battery microgrid on Highbourne Cay. The microgrid, also built to withstand a Category 5 hurricane, will provide power to up to 100 residents and guests at the island’s resort. It will also save more than 1,650 tons of CO2 emissions annually and pay for itself through diesel savings in just five to six years.

The recommendations are even being used in the largest solar project in The Bahamas to date. The 4 MW solar-plus-battery microgrid on Chub Cay is expected to be complete by mid-September. Chub Cay is a privately owned island that had been powered with diesel generators. However, the Texan owner of the island, who ironically made his money from oil and gas, realized it made financial sense to switch to solar energy to supply 90 percent of the island’s energy. Applying resilience best practices from the reports only increased costs by 5 to 7 percent. This was also a cost-effective investment to ensure that the system survives hurricane-force winds.

“Fortunately, most of these systems have not had to endure a category 5 hurricane after installation. We wouldn’t wish that on anyone,” says Chris Burgess, project director for RMI’s Global South Program. “But we have a lot of data from the surviving systems of Irma and Maria that have already allowed us to conclude that these best practices do work and that these new resilient PV systems will survive severe storms.”

Beyond The Bahamas

Other islands across the Caribbean are also using the best practices described in the reports. For example, Montserrat recently completed a 750 kW microgrid. In the event that the grid goes down, the microgrid will help provide power to a hospital, airport, assisted living apartment complex, and a number of homes in the area.

A 100 kW solar microgrid on the Grenadine island of Mayreau, deployed in 2019 by St. Vincent Electricity Services Limited with help from RMI, serves 28 percent of the island’s electricity demand. It is greatly reducing the island’s energy costs and will ensure electricity is available to critical facilities during storms.

“The Mayreau project was initially specified to withstand Category 4 winds,” says Fidel Neverson, senior project manager for RMI’s Global South Program. “That was before we saw the utter destruction caused by Hurricanes Irma and Maria to ground-mount solar arrays that were built to Category 4 specifications.”

Using best practices from the first Solar Under Storm publication, RMI and the project team completely reengineered the Mayreau solar array to a Category 5 design. “We want to give the Mayreau microgrid the best possible chance of surviving the types of devastating hurricanes that have impacted the region recently so that the island’s residents can enjoy its benefits for years to come,” Neverson adds.

And in Puerto Rico, after Hurricanes Maria and Irma caused the largest blackout in US history, RMI helped the island install solar and battery microgrids on 10 public schools. “All of our procurements require installers to adhere to Solar Under Storm principles,” says Roy Torbert, a principal with RMI’s Global South Program. “The systems on these schools were built to withstand Category 5 hurricane winds. But we’ve also seen many of them continue to provide power after the grid went down due to the earthquakes that ravaged the island in early 2020.”

Helping Develop New Policies and Codes

The third report that RMI produced, Solar Under Storm for Policymakers, emphasized that it is not only installers that have to act on the recommendations. There are many things that governments, regulators, and developers can do to improve the survivability of solar PV systems in the face of severe storms. And many policymakers throughout the Caribbean are taking that to heart. The Organization of Eastern Caribbean States adopted the best practices from the Solar Under Storm reports into its building code. And the Caribbean Development Bank uses the recommendations as part of its underwriting process for the financing of solar projects. 

Three years after we published our first Solar Under Storm report, we are happy to see all of the solar projects that have employed our recommendations. “We discovered that design, workmanship, quality materials, and quality checks were the difference between survival and failure,” said Burgess. “We realized we didn’t need a technical or manufacturing revolution, we just needed to have an eye for detail.”

Fortunately, islands throughout the Caribbean are using those details to prepare their solar systems for the ever-increasing hurricanes. In this way, we can ensure reliable, life-saving power for those who need it most.

Yamaha throws in the towel, pulls out of e-bike market in North America

Yamaha has announced to its dealers that it will be pulling its e-bikes out of the North American market at the end of this year. In the meantime, the brand says that it will offer sales of up to 60% off for its remaining inventory and continue to support its e-bikes already sold in the US for at least five more years.

Yamaha’s electric bikes have been well-received in global markets and have also received rave reviews in the US. However, the company’s higher prices make it harder to compete in the North American market, which is dominated by value-oriented models with significantly lower price points.

Yamaha’s various electric bikes designed for commuting, fitness, and mountain biking all feature higher-end components, which has resulted in the company competing more directly with premium bicycle shops. The company’s elaborate frames and in-house motors have added value to their models, yet have also contributed to a more premium price range.

Meanwhile, Yamaha hasn’t been immune to the same sales slowdown and overstocking issues that have plagued the e-bike industry over the last few years, as the company explained to its dealers in the letter seen below.

“Dear Yamaha eBike Dealer,

We want to thank you for your partnership and for your business in purchasing and retailing Yamaha eBikes, and for proudly representing the Yamaha brand. However, as you know, the combination of a post-COVID oversupply within the entire bicycle industry, coupled with a significant softening of the market, has resulted in a particularly challenging business environment where it is extremely difficult to achieve a sustainable business model. Given these market conditions, we regret to inform you that Yamaha has made the difficult decision to withdraw from the U.S. eBike business and cease wholesaling units effective the end of this year.

Yamaha Motor Corporation, U.S.A. (YMUS) entered the U.S. eBike market in 2018, and we have enjoyed the opportunity to partner with you these past six years to sell exciting, high-quality, all-road, mountain, and fitness/lifestyle eBikes.

We will continue to support your dealership in the sell down of your inventory by extending the current “Fan Promotion” program where customers may receive up to 60% off their purchase of a new Yamaha eBike. This “Fan Promotion” program will be offered on all units retailed and warranty registered through June 30, 2025. YMUS will continue to provide parts, service, and customer support in the United States both now and in support of our limited 5-year warranty.

Finally, we wish to express our sincere appreciation and gratitude to you and your staff for your dedication and support of the Yamaha eBike business.

Thank you for your understanding and support.”

Toyota to buy clean power from a .1 billion solar farm in Texas

Enbridge, a Canadian energy company, just announced it’s moving forward with an 815-megawatt (MW) solar project called Sequoia in Texas. When it’s done, it’ll be one of the largest solar farms in North America. The project’s price tag is a hefty $1.1 billion.

Enbridge’s Sequoia, around 150 miles west of Dallas, has already landed long-term power purchase agreements (PPAs) with AT&T and Toyota, ensuring most of its output is sold for years to come. This deal was highlighted in Enbridge’s third-quarter report on Friday.

Sequoia will be built in two phases, with power expected to start flowing in 2025 and 2026. Enbridge says it’s taken steps to reduce risks by securing equipment and procurement contracts in advance. Permits and purchase orders are also locked down.

Toyota’s PPA with Enbridge’s Texas solar project is part of Toyota’s broader push toward sustainability, as the automaker aims to achieve net zero by 2035 and match 45% of its purchased power with renewable electricity by 2026 as it still clings to its “diverse powertrain strategy.”

NIO's EV sales top 20,000 for the sixth straight month as new low-cost SUV shows promise

With its new electric SUV rolling out, NIO’s (NIO) sales topped the 20,000 mark again in Oct, its sixth straight month hitting the milestone.

NIO sold 20,976 vehicles last month, up 30.5% from October 2023. The NIO brand sold 16,657 vehicles, while its new “family-oriented smart vehicle brand,” Onvo, contributed 4,319 in its first full sales month.

After launching its new mid-size Onvo L60 electric SUV in September, NIO said production and deliveries are steadily ramping up.

At the end of October, NIO’s Onvo had 166 Centers and Spaces throughout 60 cities. Onvo plans to continue expanding its network to drive future growth.

NIO’s new electric SUV starts at around $21,200 (149,900) and is a direct rival to Tesla’s Model Y. The base $21K model is if you rent the battery. Even with the battery included, Onvo L60 prices still start at under $30,000 (206,900 yuan), with a CLTC range of up to 341 miles (555 km). That’s still less than the Model Y.

Tesla’s Model Y RWD starts at around $35,000 (249,900 yuan) with 344 mi (554 km) CLTC range in China.

NIO’s new Onvo brand drives higher Oct sales

NIO has often compared its new electric SUV to the Model Y, claiming it’s superior in many ways. The L60 has better consumption at 12.1 kWh/100km compared to the Model Y at 12.5 kWh/100km).

With a longer wheelbase (2,950 mm vs 2,890 mm), NIO’s electric SUV also provides slightly more interior space.

Despite the L60’s success so far, NIO believes its second Onvo model will be an even bigger hit. It could be a potential game-changer.

“If you think the L60 is good, then this new model is a much more competitive product,” NIO’s CEO William Li told CnEVPost after launching the L60. Onvo will launch a new EV every year. Following the L60, Onvo will launch a new mid-to-large-size electric SUV next year.

NIO’s leader claims the new model will be revolutionary. According to Li, it will offer even more surprises than the L60. Deliveries are planned to begin in Q3 2025.

Local reports suggest a six-or seven-seat electric SUV could hit the market even sooner. With rumors of a launch around Q1 2025, deliveries could happen as soon as May 2025.

According to sources close to the matter, the L60 is just a “stepping stone” with even more exciting EVs on the way. The source claimed the new six-seat option will start at around $42,100 (300,000 yuan).
