Trilliant validates ZigBee device interoperability testing

Floating Rotating Eco Hotel harnesses renewable energy via VAWTAU, recycles rainwater for greywater, and follows zero-waste principles. This mobile, off-grid, Qatar-based resort generates electricity by slow 360-degree rotation while offering luxury amenities.

Key Points

A mobile, off-grid hotel that rotates to generate power, uses VAWTAU, recycles greywater, and targets zero-waste.

✅ Rotates 360 deg in 24 hours to produce electricity

✅ VAWTAU system: vertical-axis turbine and sun umbrella

✅ Rain capture and greywater recycling minimize waste

A new eco-friendly, floating hotel plans to generate its own electricity by rotating while guests relax on board, echoing developments like the solar Marriott hotel in sustainable hospitality.

Led by Hayri Atak Architectural Design Studio (HAADS), the structure will be completely mobile, meaning it can float from place to place, never sitting in a permanent position. Building began in March 2020 and the architects aim for it to be up and running by 2025.

It will be based in Qatar, but has the potential to be located in different areas due to its mobility, and it sits within a region advancing projects such as solar hydrogen production that signal a broader clean-energy shift.

The design includes minimum energy loss and a zero waste principle at its core, aligning with progress in wave energy research that aims to power a clean future. As it will rotate around all day long, this will generate electrical energy to power the whole hotel.

But guests won’t feel too dizzy, as it takes 24 hours for the hotel to spin 360 degrees.

The floating hotel will stay within areas with continuous currents, to ensure that it is always rotating, drawing on ideas from ocean and river power systems that exploit natural flows. This type of green energy production is called ‘vawtau’ (vertical axis wind turbine and umbrella) which works like a wind turbine on the vertical axis, while alternative approaches like kite-based wind energy target stronger, high-altitude currents as well, and functions as a sun umbrella on the coastal band.

Beyond marine-current concepts such as underwater kites, the structure will also make use of rainwater to create power. A cover on the top of the hotel will collect rain to be used for greywater recycling. This is when wastewater is plumbed straight back into toilets, washing machines or outside taps to maximise efficiency.

The whole surface area is around 35,000 m², comparable in scale to emerging floating solar plants that demonstrate modular, water-based infrastructure, and there are a total of 152 rooms. It will have three different entrances so that there is access to the land at any time of the day, thanks to the 140-degree pier that surrounds it.

There will also be indoor and outdoor swimming pools, a sauna, spa, gym, mini golf course and other activity areas.

Ukraine-ENTSO-E Grid Synchronization links Ukraine and Moldova to the European grid via secure interconnection, matching frequency for stability, resilience, and energy security, enabling cross-border support, islanding recovery, and coordinated load balancing during wartime disruptions.

Key Points

Rapid alignment of Ukraine and Moldova into the European grid to enable secure interconnection and system stability.

✅ Matches 50 Hz frequency across interconnected systems

✅ Enables cross-border support and electricity trading

✅ Improves resilience, stability, and energy security

On February 24 Ukraine’s electric grid operator disconnected the country’s power system from the larger Russian-operated network to which it had always been linked. The long-planned disconnection was meant to be a 72-hour trial proving that Ukraine could operate on its own and to protect electricity supply before winter as contingencies were tested. The test was a requirement for eventually linking with the European grid, which Ukraine had been working toward since 2017. But four hours after the exercise started, Russia invaded.

Ukraine’s connection to Europe—which was not supposed to occur until 2023—became urgent, and engineers aimed to safely achieve it in just a matter of weeks. On March 16 they reached the key milestone of synchronizing the two systems. It was “a year’s work in two weeks,” according to a statement by Kadri Simson, the European Union commissioner for energy. That is unusual in this field. “For [power grid operators] to move this quickly and with such agility is unprecedented,” says Paul Deane, an energy policy researcher at the University College Cork in Ireland. “No power system has ever synchronized this quickly before.”

Ukraine initiated the process of joining Europe’s grid in 2005 and began working toward that goal in earnest in 2017, as did Moldova. It was part of an ongoing effort to align with Europe, as seen in the Baltic states’ disconnection from the Russian grid, and decrease reliance on Russia, which had repeatedly threatened Ukraine’s sovereignty. “Ukraine simply wanted to decouple from Russian dominance in every sense of the word, and the grid is part of that,” says Suriya Jayanti, an Eastern European policy expert and former U.S. diplomat who served as energy chief at the U.S. embassy in Kyiv from 2018 to 2020.

After the late February trial period, Ukrenergo, the Ukrainian grid operator, had intended to temporarily rejoin the system that powers Russia and Belarus. But the Russian invasion made that untenable. “That left Ukraine in isolation mode, which would be incredibly dangerous from a power supply perspective,” Jayanti says. “It means that there’s nowhere for Ukraine to import electricity from. It’s an orphan.” That was a particularly precarious situation given Russian attacks on key energy infrastructure such as the Zaporizhzhia nuclear power plant and ongoing strikes on Ukraine’s power grid that posed continuing risks. (According to Jayanti, Ukraine’s grid was ultimately able to run alone for as long as it did because power demand dropped by about a third as Ukrainians fled the country.)

Three days after the invasion, Ukrenergo sent a letter to the European Network of Transmission System Operators for Electricity (ENTSO-E) requesting authorization to connect to the European grid early. Moldelectrica, the Moldovan operator, made the same request the following day. While European operators wanted to support Ukraine, they had to protect their own grids, amid renewed focus on protecting the U.S. power grid from Russian hacking, so the emergency connection process had to be done carefully. “Utilities and system operators are notoriously risk-averse because the job is to keep the lights on, to keep everyone safe,” says Laura Mehigan, an energy researcher at University College Cork.

An electric grid is a network of power-generating sources and transmission infrastructure that produces electricity and carries it from places such as power plants, wind farms and solar arrays to houses, hospitals and public transit systems. “You can’t just experiment with a power system and hope that it works,” Deane says. Getting power where it is it needed when it is needed is an intricate process, and there is little room for error, as incidents involving Russian hackers targeting U.S. utilities have highlighted for operators worldwide.

Crucial to this mission is grid interconnection. Linked systems can share electricity across vast areas, often using HVDC technology, so that a surplus of energy generated in one location can meet demand in another. “More interconnection means we can move power around more quickly, more efficiently, more cost effectively and take advantage of low-carbon or zero-carbon power sources,” says James Glynn, a senior research scholar at the Center on Global Energy Policy at Columbia University. But connecting these massive networks with many moving parts is no small order.

One of the primary challenges of interconnecting grids is synchronizing them, which is what Ukrenergo, Moldelectrica and ENTSO-E accomplished last week. Synchronization is essential for sharing electricity. The task involves aligning the frequencies of every energy-generation facility in the connecting systems. Frequency is like the heartbeat of the electric grid. Across Europe, energy-generating turbines spin 50 times per second in near-perfect unison, and when disputes disrupt that balance, slow clocks across Europe can result, reminding operators of the stakes. For Ukraine and Moldova to join in, their systems had to be adjusted to match that rhythm. “We can’t stop the power system for an hour and then try to synchronize,” Deane says. “This has to be done while the system is operating.” It is like jumping onto a moving train or a spinning ride at the playground: the train or ride is not stopping, so you had better time the jump perfectly.

Texas PUC Spanish Power to Choose mandates bilingual parity in deregulated electricity markets, ensuring equal access to plans, transparent pricing, consumer protection, and provider listings for Spanish speakers, mirroring the English site offerings statewide.

Key Points

PUC mandate requiring identical Spanish and English plan listings for fair access in the deregulated power market.

✅ Orders parity across English and Spanish plan listings

✅ Increases transparency in a deregulated electricity market

✅ Deadline set for providers to post on both sites

The state’s Public Utility Commission has ordered that the Spanish-language version of the Power to Choose website provide the same options available on the English version of the site, a move that comes as shopping for electricity is getting cheaper statewide.

Texas is one of a handful of states with a deregulated electricity market, with ongoing market reforms under consideration to avoid blackouts. The idea is to give consumers the option to pick power plans that they think best fit their needs. Customers can find available plans on the state’s Power To Choose website, or its Spanish-language counterpart, Poder de Escoger. In theory, those two sites should have the exact same offerings, so no one is disadvantaged. But the Texas Public Utility Commission found that wasn’t the case.

Houston Chronicle business reporter Lynn Sixel has been covering this story. She says the Power to Choose website is important for consumers facing the difficult task of choosing an electric provider in a deregulated state, where electricity complaints have recently reached a three-year high for Texans.

“There are about 57 providers listed on the [English] Power to Choose website, and news about retailers like Griddy underscores how varied the offerings can be across providers. [Last week] there were only 23 plans on the Spanish Power to Choose site,” Sixel says. “If you speak Spanish and you’re looking for a low-cost plan, as of last week, it would have been difficult to find some of the really great offers.”

Mustafa Tameez, managing director of Outreach Strategists, a Houston firm that consults with companies and nonprofits on diversity, described this issue as a type of redlining.

“He’s referring to a practice that banks would use to circle areas on maps in which the bank decided they did not want to lend money or would charge higher rates,” Sixel says. “Typically it was poor minority neighborhoods. Those folks would not get the same great deals that their Anglo neighbors would get.”

DeAnn Walker, chairman of the Public Utility Commission, said she was not at all happy about the plans listings in a meeting Friday, against a backdrop where Texas utilities have recently backed out of a plan to create smart home electricity networks.

“She gave a deadline of 8 a.m. Monday morning for any providers who wanted to put their plans on the Power to Choose website, must put them on both the Spanish language and the English language versions,” Sixel says. “All the folks that I talked to really had no idea that there were different plans on both sites and I think that there was sort of an assumption.”

Gulf Power 40% One-Time Bill Decrease approved by the Florida Public Service Commission delivers a May fuel credit and COVID-19 relief, cutting residential and business costs across rate classes while supporting budgeting and energy savings.

Key Points

PSC-approved fuel credit cutting May electric bills about 40% for homes and 40-55% for businesses as COVID-19 relief.

✅ One-time May fuel credit on customer bills

✅ Residential cut ~40%; business savings 40-55% by rate class

✅ Online tools show daily usage and projected bill

Gulf Power announced that the Florida Public Service Commission unanimously approved its request to issue a one-time decrease of approximately 40% for the typical residential customer bill beginning May 1, similar to recent Georgia Power bill reductions seen elsewhere. Business customers will also see a significant one-time decrease of approximately 40-55% in May, depending on usage and rate class.

"We are pleased that the Florida Public Service Commission has approved our request to deliver this savings to our customers when they need it most. We felt that this was the right thing to do, especially during times like these," said Gulf Power President Marlene Santos. "Our customers and communities now more than ever count on the reliable and affordable energy we deliver, and we are pleased that May bills will reflect this additional, significant savings for our customers."

In Florida, fuel savings are typically refunded to customers over the remainder of the year to provide level, predictable bills. However, given the emergent and significant financial challenges facing many customers due to COVID-19, Gulf Power instead sought approval to give customers the total annual savings in their May bill, similar to a lump-sum electricity credit approach, which will be reflected as a line-item fuel credit on their May statement.

New tools to help save energy and money

Many customers are working from home and, in general, staying at home more. More time and extra people in the home will likely increase power usage, which could lead to higher monthly bills.

Gulf Power recently added new tools to our customers' online account portal to help them better understand and manage their energy usage, including their monthly projected bill amount and a breakdown of daily energy usage, which is available for most residential customers*. Customers can now see their previous day's energy usage using their online account portal to help them more easily understand how their previous day's activities impacted energy usage, allowing them to quickly make adjustments to keep bills low. The new projected bill feature is a valuable tool to assist customers in budgeting for their next month's energy bill.

Additional energy-saving tips that can be implemented with no additional cost or equipment are also available. As always, Gulf Power's free online Energy Checkup tool will provide customers with a customized report based on their home's actual energy use.

Helping customers pay their bills

Gulf Power has a long history of working with its customers during difficult times, including periods of pandemic-related energy insecurity, and will continue to do so. Gulf Power encourages customers that are having difficulty paying their energy bill to visit GulfPower.com/help to view available resources that can provide assistance to qualifying customers.

Customers are encouraged to pay their electric bill balance each month to avoid building up a large balance, which they will continue to bear responsibility for. Gulf Power will work with the customer's personal situation and assist with a solution, similar to how utilities in Texas have waived fees during this period, to help customers fulfill their personal responsibility for their Gulf Power balance.

Those who can afford or want to help others who may need assistance with their energy bill can make a donation to Project SHARE in your online customer portal. Project SHARE donations are added to a customer's monthly bill and all contributions are distributed to local offices of The Salvation Army. Customers in need of utility bill assistance can apply for Project SHARE assistance at The Salvation Army office in their county.

Supporting our communities

The Gulf Power Foundation gave $500,000 to United Way organizations across Northwest Florida to assist those most vulnerable during this time, which has helped support food, housing and other essential needs throughout the region. In addition, the Foundation recently made a $10,000 donation to Feeding the Gulf Coast and launched an employee donation campaign to provide food for our neighbors in need, while Entergy emergency relief fund offers a similar example of industry support. In total, Gulf Power and its fellow NextEra Energy companies and employees have so far committed more than $4 million in COVID-19 emergency assistance funds that will be distributed directly to those in need and to partner organizations working on the frontlines of the crisis to provide critical support to the most vulnerable members of the community.

Lower fuel costs are enabling Gulf Power to issue a one-time decrease of approximately 40% for the typical residential customer bill in May, even as FPL faces a hurricane surcharge controversy in the state
- a significant savings amid the ongoing COVID-19 pandemic

Gulf Power will deliver savings to customers through a one-time bill decrease, rather than the standard practice of spreading out savings over the remainder of the year, even as FPL proposes multi-year rate hikes elsewhere

Meaford Pumped Storage Project aims to balance the grid with hydro-electric generation, a hilltop reservoir, and transmission lines near Georgian Bay, pending environmental assessment, permitting, and federal review of impacts on fish and drinking water.

Key Points

TC Energy proposal to pump water uphill off-peak and generate 1,000 MW at peak, pending studies and approvals.

✅ Balances grid by storing off-peak energy and generating at peak.

✅ Requires reservoir, break wall, transmission lines, generating station.

✅ Environmental studies and federal review underway before approvals.

Plans for a $3.3 billion hydro-electric project in Meaford are still in the early study stages, but some residents have concerns about what it might mean for the environment, as past Site C stability issues have illustrated for large hydro projects.

A one-year permit was granted for TC Energy Corporation (TC Energy) to begin studies on the proposed location back in May, and cross-border projects like the New England Clean Power Link require federal permits as well to proceed. Local municipalities were informed of the project in June.

TC Energy is proposing to have a pumped storage project at the 4th Canadian Division Training (4CDTC) Meaford property, which is on federal lands.

A letter sent to local municipalities explains that the plan is to balance supply and demand on the electrical grid by pumping water uphill during off-peak hours. It would then release the water back into Georgian Bay during peak periods, generating up to 1,000 megawatts of electricity.

The project is expected to create 800 jobs over four years of construction, in addition to long-term operational positions.

According to the company's website, the proposed pump station would require a large reservoir on the military base, a generating station, transmission lines infrastructure, and a break wall 850 metres from shore.

Some residents fear the project will threaten the bay and the fish, echoing Site C dam concerns shared with northerners, and the region's drinking water.

Meaford's mayor says the town has no jurisdiction on federal lands, but that a list of concerns has been forwarded to the company, while Ontario First Nations have urged government action on urgent transmission needs elsewhere.

TC Energy will tackle preliminary engineering and environmental studies to determine the feasibility of the proposed location, which could take up to two years.

Once the assessments are done, they need to be presented to the government for further review and approval, as seen when Ottawa's Site C stance left work paused pending a treaty rights challenge.

TC Energy's website states that the company anticipates construction to begin in 2022 if it gets all the go-ahead, with the plant to begin operations four years later.

Input from residents is being collected until April 2020, similar to when the National Energy Board heard oral traditional evidence on the Manitoba-Minnesota transmission line.

✅ 14.5 GWh solar from Schleswig-Holstein via ane.energy

✅ Powers Mainz HQ and plants in GrFCnenplan, Mitterteich, Landshut

✅ Two-year CPPA covers ~5% of Schott's German electricity needs

Schott, a leading specialty glass manufacturer, is advancing its sustainability initiatives in step with Germany's energy transition by integrating green electricity into its operations. Through a Corporate Power Purchase Agreement (CPPA) with green energy specialist ane.energy, Schott aims to significantly reduce its carbon footprint and move closer to its goal of climate-neutral production by 2030.

Transition to Renewable Energy

As of February 2025, amid a German renewables milestone for the power sector, Schott has committed to sourcing approximately 14.5 gigawatt-hours of clean energy annually from a solar park in Schleswig-Holstein, Germany. This renewable energy will power Schott's headquarters in Mainz and its plants in Grünenplan, Mitterteich, and Landshut. The CPPA covers about 5% of the company's annual electricity needs in Germany and is initially set for a two-year term, reflecting lessons from extended nuclear power during recent supply challenges.

Strategic Implementation

To achieve climate-neutral production by 2030, Schott is focusing on transitioning from gas to electricity sourced from renewable sources like photovoltaics, alongside complementary pathways such as hydrogen-ready power plants being developed nationally. Operating a single melting tank requires energy equivalent to the annual consumption of up to 10,000 single-family homes. Therefore, Schott has strategically selected suitable plants for this renewable energy supply to meet its substantial energy requirements.

Industry Leadership

Schott's collaboration with ane.energy demonstrates the company's commitment to sustainability and its proactive approach to integrating renewable energy into industrial operations. This partnership not only supports Schott's decarbonization goals but also sets a precedent for other manufacturers in the glass industry to adopt green energy solutions, mirroring advances like green hydrogen steel in heavy industry.

Schott's initiative to power its German glass plants with green electricity underscores the company's dedication to environmental responsibility and its strategic efforts to achieve climate-neutral production by 2030, aligning with the national coal and nuclear phaseout underway. This move reflects a broader trend in the manufacturing sector toward sustainable practices and the adoption of renewable energy sources, even as debates continue over a possible nuclear phaseout U-turn in Germany.
