Dewa in China to woo renewable energy firms

Puerto Rico Microgrid Regulations outline renewable energy, CHP, and storage standards, enabling islanded systems, PREPA interconnection, excess energy sales, and IRP alignment to boost resilience, distributed resources, and community power across the recovering grid.

Key Points

Rules defining microgrids, requiring 75 percent renewables or CHP, and setting interconnection and PREPA fee frameworks.

✅ 75 percent renewables or CHP; hybrids allowed

✅ Registration, engineer inspection, and annual generation reports

✅ PREPA interconnection fees; excess energy sales permitted

The Puerto Rico Energy Commission unveiled 29 pages of proposed regulations last week for future microgrid installations on the island.

The regulations, which are now open for 30 days of public comment, synthesized pages of responses received after a November 10 call for recommendations. Commission chair José Román Morales said it’s the most interest the not-yet four-year-old commission has received during a public rulemaking process.

The goal was to sketch a clearer outline for a tricky-to-define concept -- the term "microgrid" can refer to many types of generation islanded from the central grid -- as climate pressures on the U.S. grid mount and more developers eye installations on the recovering island.

“There’s not a standard definition of what a microgrid is, not even on the mainland,” said Román Morales.

According to the commission's regulation, “a microgrid shall consist, at a minimum, of generation assets, loads and distribution infrastructure. Microgrids shall include sufficient generation, storage assets and advanced distribution technologies, including advanced inverters, to serve load under normal operating and usage conditions.”

All microgrids must be renewable (with at least 75 percent of power from clean energy), combined heat and power (CHP) or hybrid CHP-and-renewable systems. The regulation applies to microgrids controlled and owned by individuals, customer cooperatives, nonprofit and for-profit companies, and cities, but not those owned by the Puerto Rico Electric Power Authority (PREPA). Owners must submit a registration application for approval, including a certification of inspection from a licensed electric engineer, and an annual fuel, generation and sales report that details generation and fuel source, as well as any change in the number of customers served.

Microgrids, like the SDG&E microgrid in Ramona in California, can interconnect with the PREPA system, but if a microgrid will use PREPA infrastructure, owners will incur a monthly fee. That amounts to $25 per customer up to a cap of $250 per month for small cooperative microgrids. The cost for larger systems is calculated using a separate, more complex equation. Operators can also sell excess energy back to PREPA.

Big goals for the island's future grid

In total, 53 groups and companies, including Sunnova, AES, the Puerto Rico Solar Energy Industries Association (PR-SEIA), the Advanced Energy Management Alliance (AEMA), and the New York Smart Grid Consortium, submitted their thoughts about microgrids or, in many cases, broader goals for the island’s future energy system. It was a quick turnaround: The Puerto Rico Energy Commission offered a window of just 10 days to submit advice, although the commission continued to accept comments after the deadline.

“PREC wanted the input as fast as possible because of the urgency,” said AES CEO Chris Shelton.

AES’ plan includes a network of “mini-grids” that could range in size from several megawatts to one large enough to service the entire city of San Juan.

“The idea is, you connect those to each other with transmission so they can have a co-optimized portfolio effect and lower the overall cost,” said Shelton. “But they would be largely autonomous in a situation where the tie-lines between them were broken.”

According to estimates provided in AES’ filing, utility-scale solar installations over 50 megawatts on the island could cost between $40 and $50 per megawatt-hour. Those prices make solar located near load centers an economic alternative to the island’s fossil-fuel generating plants. The utility’s analysis showed that a 10,000-megawatt solar system could replace 12,000 gigawatt-hours of fossil generation, with 25 gigawatt-hours of battery storage leveling out load throughout the day. Puerto Rico’s peak load is 3,000 megawatts.

In other filings, PR-SEIA urged a restructuring of FEMA funds so they’re available for microgrid development. GridWise Alliance wrote that plans should consider cybersecurity, and AEMA recommended the commission develop an integrated resource plan (IRP) that includes distributed energy resources, microgrids and non-wires alternatives.

An air of optimism, though 1.5 million are still without power

After the commission completes the microgrid rulemaking, a new IRP is next on the commission’s to-do list. PREPA must file that plan in July, and regulators are working furiously to make sure it incorporates the recent flood of rebuilding recommendations from the energy industry.

Though the commission has the final say when it comes to approval of the plan, PREPA will lead the IRP process. The utility’s newly formed Transformation Advisory Council (TAC), a group of 11 energy experts, will contribute.

With that group, along with New York’s Resiliency Working Group, lessons from California's grid transition, the Energy Commission, the utility itself, and the dozens of other clean energy experts and entrepreneurs who want to offer their two cents, the energy planning process has a lot of moving parts. But according to Julia Hamm, CEO of the Smart Electric Power Alliance and a member of both the Energy Resiliency Working Group and the TAC, those working to establish standards for Puerto Rico’s future are hitting their stride.

“Certainly over the past three months, it has been a bit of a challenge to ensure that everybody has been coordinating efforts. Just over the past couple of weeks, we’ve seen some good progress on that front. We’re starting to see a lot more communication,” she said, adding that an air of optimism has settled on the process. “The key stakeholders all have a very common vision for Puerto Rico when it comes to the power sector.”

Nisha Desai, a PREPA board member who is liaising with the TAC, affirmed that collaborators are on the same page. “Everyone is violently in agreement that the future of Puerto Rico involves renewables, microgrids and distributed generation,” she said.

The TAC will hold its first in-person meeting in mid-January, and has already consulted with the utility on its formal fiscal plan submission, due January 10.

Though many taking part in the process feel the once-harried recovery is beginning to adopt a more organized approach, Desai acknowledges that “there are a lot of people in Puerto Rico who feel forgotten.”

Puerto Rico’s current generation sits at just 72.6 percent, in a nation facing longer, more frequent outages due to extreme weather. The government recently offered its first estimate that about half the island, 1.5 million residents, remains without power.

In late December and into January, 1,500 more crewmembers from 18 utilities in states as far flung as Minnesota, Missouri and Arizona will land on the island to aid further restoration through mutual aid agreements.

“The system is getting up to speed, getting to 100 percent, but there’s still some instability,” said Román Morales. “Right now it’s a matter of time.”

Snow-powered nanogenerator harvests static electricity from falling snow using a silicone triboelectric design, enabling energy harvesting, solar panel support during snowfall, and dual-use sensing for weather monitoring and wearable winter sports analytics.

Key Points

A silicone triboelectric device that harvests snowDcharge to generate power and enable sensing.

✅ Triboelectric silicone layer captures charge from falling snow.

✅ Integrates with solar arrays to maintain power during snowfall.

✅ Functions as weather and motion sensor for winter sports.

Scientists from University of California, Los Angeles and McMaster University have invented a nanogenerator that creates electricity from falling snow.

Most Canadians have already seen a mini-version of this, McMaster Prof. Ravi Selvaganapathy told CTV’s Your Morning. “We find that we often get shocked in the winter when it’s dry when we come in into contact with a conductive surface like a doorknob.”

The thin device works by harnessing static electricity: positively-charged, falling snow collides with the negatively-charged silicone device, which produces a charge that’s captured by an electrode.

“You separate the charges and create electricity out of essentially nothing,” Richard Kaner, who holds UCLA’s Dr. Myung Ki Hong Endowed Chair in Materials Innovation and whose lab has explored turning waste into graphene, said in a press release.

“The device can work in remote areas because it provides its own power and does not need batteries or reliance on home storage systems such as the Tesla Powerwall, which store energy for later use,” he said, explaining that the device was 3D printed, flexible and inexpensive to make because of the low cost of silicone.

“It’s also going to be useful in places like Canada, where we get a lot of snow and are pursuing a net-zero grid by 2050 to cut emissions. We can extract energy from the environment,” Selvaganapathy added.

The team, which also included scientists from the University of Toronto, published their findings in Nano Energy journal last year, but a few weeks ago, they revealed the device’s more practical uses.

About 30 per cent of the Earth’s surface is covered by snow each winter, which can significantly limit the energy generated by solar panels, including rooftop solar grids in cold climates.

So the team thought: why not simply harness electricity from the snow whenever the solar panels were covered?

Integrating their device into solar panel arrays could produce a continuous power supply whenever it snows, potentially as part of emerging virtual power plants that aggregate distributed resources, study co-author and UCLA assistant researcher Maher El-Kady explained.

The device also serves as a weather-monitoring station by recording how much snow is falling and from where; as well as the direction and speed of the wind.

The team said they also want to incorporate their device into weather sensors to help them better acquire and transmit electronic signals, supporting initiatives to use AI for energy savings across local grids. They said several Toronto-based companies -- which they couldn’t name -- have expressed interest in partnering with them.

Selvaganapathy said the device would hop on the trend of “sensors being incorporated into what we wear, into our homes and even to detect electricity theft in some markets in order to monitor a lot of the things that are important to us”

But the device’s arguably larger potential use is being integrated into technology to monitor athletes and their performances during winter sports, such as hiking, skiing and cross-country skiing.

Up to now, the movement patterns used during cross-country skiing couldn’t be detected by a smart watch, but this device may be able to.

Scientists such as Kaner believe the technology could usher in a new era of self-monitoring devices to assess an athlete’s performance while they’re running, walking or jumping.

The device is simply a proof of concept and the next step would be figuring out how to generate more electricity and integrate it into all of these potential devices, Selvaganapathy said.

✅ Requires robust charging infrastructure and OEM partnerships

In a significant move towards sustainable transportation, a prominent U.S. nonprofit has announced plans to invest $250 million in leasing electric trucks for operations at California ports. This initiative aims to reduce air pollution and promote greener logistics, responding to the urgent need for environmentally friendly solutions in the transportation sector.

Addressing Environmental Concerns

California’s ports, particularly the Port of Los Angeles and the Port of Long Beach, are among the busiest in the United States. However, they also contribute significantly to air pollution due to the heavy reliance on diesel trucks for cargo transport. These ports are essential for the economy, facilitating trade and commerce, but the environmental toll is considerable. Diesel emissions are linked to respiratory issues and other health problems in nearby communities, which often bear the brunt of pollution.

The nonprofit's investment in electric trucks is a critical step towards mitigating these environmental challenges. By transitioning to electric vehicles (EVs), the project aims to significantly cut emissions from port operations, contributing to California's broader goals of reducing greenhouse gas emissions and improving air quality.

The Scale of the Initiative

This ambitious initiative involves leasing a fleet of electric trucks that will operate within the ports and surrounding areas. The $250 million investment is expected to facilitate the acquisition of hundreds of electric vehicles, which will replace conventional diesel trucks used for cargo transport. This fleet will help demonstrate the viability and effectiveness of electric trucks in heavy-duty applications, paving the way for broader adoption.

The plan includes partnerships with established electric truck manufacturers, such as the Volvo VNR Electric platform, and local logistics companies to ensure seamless integration of these vehicles into existing operations. By collaborating with industry leaders, the initiative seeks to establish a model that can be replicated in other major logistics hubs across the country.

Economic and Community Benefits

The introduction of electric trucks is expected to yield multiple benefits, not only in terms of environmental impact but also economically. As these trucks begin operations, and as other fleets adopt electric mail trucks, they will create jobs within the green technology sector, from manufacturing to maintenance and charging infrastructure development. The project is anticipated to stimulate local economies, providing new opportunities in communities that have historically been disadvantaged by pollution.

Moreover, the initiative is poised to enhance public health. By reducing diesel emissions, the nonprofit aims to improve air quality for residents living near the ports, and emerging research links EV adoption to fewer asthma-related ER visits in local communities. This could lead to decreased healthcare costs associated with pollution-related illnesses, benefiting both the community and the healthcare system.

Challenges Ahead

While the initiative is promising, challenges remain. The successful implementation of electric trucks at scale requires a robust charging infrastructure capable of supporting the significant power needs of a large fleet. Additionally, the transition from diesel to electric vehicles involves significant upfront costs, even with leasing arrangements. Ensuring that logistics companies can manage these costs effectively will be crucial for the project's success.

Furthermore, electric trucks currently face limitations in terms of range and payload capacity compared to their diesel counterparts. Continued advancements in battery technology and infrastructure development will be necessary to fully realize the potential of electric vehicles in heavy-duty applications.

The Bigger Picture

This investment in electric trucks aligns with broader national and global efforts to combat climate change. As governments and organizations commit to reducing carbon emissions, initiatives like this one represent crucial steps toward achieving sustainability goals, and ports worldwide are also piloting complementary technologies like hydrogen-powered cranes to decarbonize cargo handling.

California has set ambitious targets for reducing greenhouse gas emissions, including a mandate for all new trucks to be zero-emission by 2045. The nonprofit’s investment not only supports these goals, amid ongoing debates over funding priorities in the state, but also serves as a pilot program that could inform future policies and investments in clean transportation.

The $250 million investment in electric trucks for California ports marks a significant milestone in the push for sustainable transportation solutions. By addressing the urgent need for cleaner logistics, this initiative stands to benefit the environment, public health, and the economy. As the project unfolds, it will be closely watched as a potential model for similar efforts across the country and beyond, with developments such as the all-electric berth at London Gateway illustrating parallel advances, highlighting the critical intersection of innovation, sustainability, and community well-being in the modern logistics landscape.

French Antitrust Fines for Electrical Cartel expose price fixing by Schneider Electric, Legrand, Rexel, and Sonepar, after a Competition Authority probe into electrical distribution, collusion, and compliance breaches impacting market competition and customers.

Key Points

Penalties on Schneider Electric, Legrand, Rexel, and Sonepar for electrical price fixing, upholding competition law.

✅ Competition Authority fined four major suppliers.

✅ Collusion raised prices across construction and industry.

✅ Firms bolster compliance programs and training.

In a significant crackdown on corporate malfeasance, French authorities have imposed hefty fines on four major electrical equipment companies—Schneider Electric, Legrand, Rexel, and Sonepar—after concluding a price-fixing investigation. The total fines amount to approximately €500 million, underscoring the seriousness with which regulators are addressing anti-competitive practices in the electrical distribution sector, even as France advances a new electricity pricing scheme to address EU concerns.

Background of the Investigation

The probe, initiated by France’s Competition Authority, sought to uncover collusion among these leading firms regarding the pricing of electrical equipment and services between 2005 and 2012. This investigation is part of a broader initiative to promote fair competition within the market, as Europe prepares to revamp its electricity market to bolster transparency, ensuring that consumers and businesses alike benefit from competitive pricing and innovative products.

The inquiry revealed that these companies had engaged in illicit agreements to fix prices and coordinate their market strategies, limiting competition in a sector critical to both the economy and infrastructure. The findings indicated that the collusion not only stifled competition but also led to inflated prices for customers, illustrating why rolling back electricity prices is often more complex than it appears for customers across various sectors, from construction to manufacturing.

The Fines Imposed

Following the conclusion of the investigation, the fines levied against the companies were substantial. Schneider Electric faced the largest penalty, receiving a fine of €220 million, while Legrand was fined €150 million. Rexel and Sonepar were each fined €70 million and €50 million, respectively. These financial penalties serve as a deterrent to other companies that might consider engaging in similar practices, reinforcing the message that anti-competitive behavior will not be tolerated.

The fines are particularly significant given the size and influence of these companies within the electrical equipment market. Their combined revenues amount to billions of euros annually, making the repercussions of their actions far-reaching. As major players in the industry, their pricing strategies have a direct impact on numerous sectors, from residential construction to large-scale industrial projects.

Industry Reactions

The response from the affected companies has varied. Schneider Electric expressed its commitment to compliance and transparency, acknowledging the importance of adhering to competition laws, amid ongoing EU electricity reform debates that influence market expectations.

Legrand also emphasized its commitment to fair competition, noting that it has taken steps to enhance its compliance framework in response to the investigation. Rexel and Sonepar similarly reaffirmed their dedication to ethical business practices and their intention to cooperate with regulators in the future.

Industry experts have pointed out that these fines, while significant, may not be enough to deter large corporations from engaging in similar behavior unless accompanied by a broader cultural shift within the industry. There is a growing call for enhanced oversight and stricter penalties to ensure that companies prioritize ethical conduct over short-term profits.

Implications for the Market

The fines imposed on Schneider, Legrand, Rexel, and Sonepar could have broader implications for the electrical equipment market and beyond. They signal to other companies within the sector that regulatory bodies are vigilant, even as nine EU countries oppose electricity market reforms proposed as fixes for price spikes, and willing to take decisive action against anti-competitive practices. This could foster a more competitive environment, ultimately benefiting consumers through better prices and enhanced product offerings.

Moreover, the case highlights the importance of regulatory bodies in maintaining fair market conditions. As industries evolve, ongoing vigilance from competition authorities will be necessary to prevent similar instances of collusion and ensure that markets remain competitive and innovative, as seen when New York opened a formal review of retail energy markets.

The recent fines imposed on Schneider Electric, Legrand, Rexel, and Sonepar mark a significant moment in France's ongoing battle against corporate price-fixing and anti-competitive practices, occurring as the government and EDF reached a deal on electricity prices to balance market pressures. With total penalties exceeding €500 million, the investigation underscores the commitment of French authorities to uphold market integrity and protect consumer interests.

As the industry reflects on these developments, it remains crucial for companies to prioritize compliance and ethical business practices. The ultimate goal is to create an environment where competition thrives, innovation flourishes, and consumers benefit from fair pricing. This case serves as a reminder that transparency and accountability are vital in maintaining the health of any market, particularly one as essential as the electrical equipment sector.

UK Free Electricity Debate weighs soaring energy prices against market regulation, renewables, and social equity, examining price caps, funding via windfall taxes, grid investment, and consumer protection in the UK's evolving energy policy landscape.

Key Points

A policy dispute over free power, balancing consumer relief with market stability, renewables, and investment.

✅ Pros: relief for households; boosts efficiency and green adoption.

✅ Cons: risks to market signals, quality, and grid investment.

✅ Policy options: price caps, windfall taxes, targeted subsidies.

In recent months, the debate over free electricity in the UK has intensified, revealing a divide within the energy sector. With soaring energy prices and economic pressures impacting consumers, the discussion around providing free electricity has gained traction. However, the idea has sparked significant controversy among industry stakeholders, each with their own perspectives on the feasibility and implications of such a move.

The Context of Rising Energy Costs

The push for free electricity is rooted in the UK’s ongoing energy crisis, exacerbated by geopolitical tensions, supply chain disruptions, and the lingering effects of the COVID-19 pandemic. As energy prices reached unprecedented levels, households faced the harsh reality of skyrocketing bills, prompting calls for government intervention to alleviate financial burdens.

Supporters of free electricity argue that it could serve as a vital lifeline for struggling families and businesses. The proposal suggests that by providing a certain amount of electricity for free, the government could help mitigate the effects of rising costs while encouraging energy conservation and efficiency.

Industry Perspectives

However, the notion of free electricity has not been universally embraced within the energy sector. Some industry leaders express concerns about the financial viability of such a scheme. They argue that providing free electricity could undermine the market dynamics that incentivize investment in infrastructure and renewable energy, in a market already exposed to natural gas price volatility today. Critics warn that if energy companies are forced to absorb costs, it could lead to diminished service quality and investment in necessary advancements.

Additionally, there are worries about how free electricity could be funded. Proponents suggest that a tax on energy companies could generate the necessary revenue, but opponents question whether this would stifle innovation and competition. The fear is that placing additional financial burdens on energy providers could ultimately lead to higher prices in the long run.

Renewable Energy and Sustainability

Another aspect of the debate centers around the UK’s commitment to transitioning to renewable energy sources. Supporters of free electricity emphasize that such a policy could encourage more widespread adoption of green technologies by making energy more accessible. They argue that by removing the financial barriers associated with energy costs, households would be more inclined to invest in solar panels, heat pumps, and other sustainable solutions.

On the other hand, skeptics contend that the focus should remain on ensuring a stable and reliable energy supply as the UK moves toward its climate goals. They caution against implementing policies that might disrupt the balance of the energy market, potentially hindering the necessary investments in renewable infrastructure.

Government's Role

As discussions unfold, the government’s role in this debate is crucial. Policymakers must navigate the complex landscape of energy regulation, market dynamics, and consumer needs. The government has already introduced measures aimed at assisting vulnerable households, such as energy price caps and direct financial support. However, the question remains whether these initiatives go far enough in addressing the root causes of the energy crisis.

In this context, the government faces pressure from both consumers demanding relief and industry leaders advocating for market stability, including proposals to end the link between gas and electricity prices to curb price volatility. The challenge lies in finding a middle ground that balances immediate support for households with long-term sustainability and investment in the energy sector.

Future Implications

The ongoing debate about free electricity in the UK underscores broader themes related to energy policy, market regulation, and social equity, with rising electricity prices abroad offering context for comparison. As the country navigates its energy transition, the decisions made today will have far-reaching implications for both consumers and the industry.

If the government chooses to pursue a model that includes free electricity, it will need to carefully consider how to implement such a system without jeopardizing the market. Transparency, stakeholder engagement, and thorough impact assessments will be essential to ensure that any new policies are sustainable and equitable.

Conversely, if the concept of free electricity is ultimately rejected, the focus will likely shift back to addressing energy costs through other means, such as enhancing energy efficiency programs or increasing support for vulnerable populations.

The divide within the UK’s energy industry regarding free electricity highlights the complexities of balancing consumer needs with market stability. As the energy crisis continues to unfold, the conversations surrounding this issue will remain at the forefront of public discourse. Ultimately, finding a solution that addresses the immediate challenges while promoting a sustainable energy future will be key to navigating this critical juncture in the UK’s energy landscape.
