Early autumn saw the return of Solar & Storage Live UK: the nation’s largest platform for solar installers and manufacturers to meet, network, and discover new innovations.
At the show, Solar&StorageXtra caught up with Craig Bilboe, Country Manager UK & Ireland for EcoFlow.
With his extensive background in energy technology and business development, Craig offers a sharp perspective on navigating market regulations and installer needs.
“As we move into the winter period, we’re now really looking at concerns around grid stability and power outages. Our Gateway will really address some of those concerns, as well as the rising cost of energy.”
Since we last caught up with EcoFlow at Solar & Storage Live London, what has been new for the company?
Craig: Lots of things have happened. So, we have new products to release here at the show. We have the Gateway, which is really important and is being asked for by our installation partners. They’re craving our Gateway, so that’s really good.
And we have some, the new PowerInsight and our AI functionality, which is something unique to the industry. And I think actually, there’s a whole host of benefits to incorporating AI.
Now, we have to be very careful in delivering this message to consumers because everything has AI. But EcoFlow are the only company in this arena that I know of, in our industry, that is offering a specific AI to the energy storage market.
This will have huge benefits to not only the existing consumers, but also people who may never have had access to dynamic tariffs or have been able to capitalise on savings.
This product is probably the most exciting for me as an individual, because there’s a huge opportunity for energy saving for end users that may be in a social housing sector or may have some physical challenges, or might find it very difficult to access traditional dynamic tariffs. We have a product here that could potentially change the industry.
So, as usual, EcoFlow attends Solar & Storage Live UK to present and bring new products to the market.
What drove EcoFlow to open a UK office, and why choose Birmingham as the location?
Craig: We opened our UK HQ in Birmingham this Autumn. Opening an office here is important for our installation partners because we need to demonstrate as a manufacturer that we’re investing not only in the local community but also tin he region and the country as a whole.
Our installers really want to be able to have a location where they can come and get trained. They’ll have the comfort that we’re here for the long period, and that we’re here to support them, not just for now, but for the coming years too.
Overall, we think it’s vitally important that we have a location where everyone can come and learn more about EcoFlow.
What opportunities or challenges are you targeting in the UK residential and commercial solar-storage sectors?
Craig: There are lots of challenges and opportunities we’re looking to tackle. But, to that end, our Gateway is something where end users are really starting to look at.
As we move into the winter period, we’re now really looking at concerns around grid stability and power outages. Our Gateway will really address some of those concerns, as well as the rising cost of energy.
Over time, I think we’ll see an increased demand for our batteries, but also our different solutions, such as off-grid scenarios and all the other functionalities.
What’s your long-term vision for EcoFlow in the UK and Europe?
Craig: We’ve had a presence in the UK for over three years; we wouldn’t have invested in our new office unless we wanted to be here for the long term.
We want to continue to bring new products, new innovations into the European market and beyond, support our installers, and maintain our large presence in the home energy sector.
Really, we want to be able to provide good products for our installers, which add benefits to the end users and continue to play a part in our industry.
Why is EcoFlow a repeat exhibitor of Solar & Storage Live?
Craig: Solar & Storage Live UK is probably our most important vehicle to access new installers.
We’ve put all our focus on this event to demonstrate – or at least showcase – our new products. We want to demonstrate our functions and all the great things about EcoFlow.
This [show] is probably the best vehicle now that we can see to reach all new installers, touch base with our existing installers, and network within the industry as well.
I would say that this is probably the most important thing that we do every single year to generate new business.
Catch more of Craig’s insights in the Solar&StorageXtra podcast, where Craig discusses how AI-driven energy management can transform the storage sector.

Press Release
GoodWe have officially launched the next generation of their ESA Series Residential All-in-One Solution, bringing expanded power options, larger battery capacity, and smarter control to meet diverse household demands.
The single-phase home storage solution is available with a hybrid inverter between 3 and 10 kW and stacked battery modules for 5 to 48 kWh storage capacity, integrating into one compact unit.
Combining rapid charge & discharge, robust safety features, and a user-friendly design, it is tailored to deliver a quieter, easier, and more flexible energy experience for families.
More options, more flexibility
The ESA All-in-One offers a wide range of possibilities to combine inverters and batteries for different household needs. Available in six power ratings of 3 – 3.6 – 5 – 6 – 8 and 10 kW, the inverter sitting on top can be freely combined with up to six battery modules with a storage capacity of 5 or 8 kWh. The storage solution can be upgraded at any time, adding new batteries to the existing setup.
This way, the system grows alongside the end users’ evolving energy needs. Designed for long-term use, the ESA comes with a conditional 10-year solution warranty, covering both the inverter and battery modules.
Installation is equally convenient with one-click upgrade and configuration; the ESA Series can be set up in as little as 10 minutes, significantly lowering the time and effort needed by the installer.
With an IP66 rating, the system can be installed inside or outside of the home and functions at temperatures as low as -18°C thanks to optional heating elements. No matter where it is installed, the design combines a modern look suitable for every home with fanless architecture, resulting in quiet operation below 35 decibels.
Both floor and wall mounting (with limited storage capacity due to the weight) are possible.
Smarter power for lower cost
The residential ESA is designed to help households lower electricity costs by increasing efficiency and limiting upfront spending. By supporting a maximum MPPT current of 20A on the PV side, larger capacity modules can be used with the system, and the 200% PV oversizing allows for more generation during off-peak hours and cloudy days.
The low startup voltage of 50V enables a longer operational time, further increasing the effective time of use. The inverter unit also allows for full usage when demand and solar yield peak, providing 100% supply to power the loads and charging the battery at full rate at the same time.
The load control and monitoring enable the inverter, together with a GMK110 or GM330 smart meter, to dynamically turn on or modulate flexible electric loads, like heat pumps or water heaters, thus improving the self-consumption ratio.
The battery modules consist of high-quality lithium iron phosphate (LiFePO4) cells and have a 1C charge/discharge rate for faster energy cycles. In practice, this means the system can achieve the same power output with fewer batteries compared to offers with a lower C-rate. This makes it suitable for high instantaneous power scenarios such as load peak shaving and frequency regulation.
Other operation modes include optimised self-use, backup operation, optimised time of use, smart charging and off-grid mode. The off-grid mode is ideal for remote areas and locations without grid access, allowing an independent power supply with solar. Strong scalability of up to 6 inverters and 288 kWh storage makes the solution suitable for even larger locations.
The integrated backup function switches on in less than 4 milliseconds in the event of a power outage. This is fast enough for appliances like computers, lights, or Wi-Fi routers to continue operating without interruption. The backup is built in the system and doesn’t require any additional equipment.
Safety and Security
Safety and Security are at the heart of all GoodWe products, and the ESA Residential Series provides a high level of safety standards. With six-layer safety protection from cell level to system level and emergency protection including aerosol-based fire extinguishing, the system covers risks such as overheating, overcurrent, and short circuits.
Adding another layer of protection, the ESA Series is equipped with AI-driven AFCI 3.0 technology, which intelligently detects and prevents arc faults. This greatly reduces the risk of electrical fires, giving homeowners peace of mind that their families and properties are well protected.
The ESA All-in-One solution also comes with the new Wi-Fi/LAN Kit 2.0 in the box, offering cybersecurity features according to the “EN 18031:2024” standard, having obtained CE-RED certification.
The certification includes key features like password security, secure authentication during commissioning, signed and validated firmware updates, as well as personal data protection.

Distributed Energy Infrastructure (DEI) has completed a 7.1MW solar and 4MW battery storage project in Massachusetts, USA, on a site formerly occupied by a chemical manufacturing facility.
The land had been classified as an EPA Superfund site due to severe soil contamination, including asbestos.
The project, owned by Syncarpha Capital with racking provided by Terrasmart, was named a finalist in Solar Builder’s 2025 Project of the Year Awards in the 1–10MW category.
To ensure safe construction on the contaminated site, DEI implemented a series of environmental and health safeguards. Crews trained in hazardous materials handling followed specialised safety protocols, and excavation was kept to a minimum.
Most electrical infrastructure was built above ground to avoid disturbing the soil, while the system was designed around existing structures, such as old concrete slabs, to reduce site disturbance.
The company also worked with six regulatory agencies and developed contingency plans in case of hazardous material discoveries. When asbestos was found, certified specialists managed its removal under regulatory oversight.
“Projects like Acton show what it takes to responsibly bring clean energy to communities while addressing the challenges of building on historically contaminated land,” said Sean Harrington, President and CEO of Distributed Energy Infrastructure.
“By transforming a brownfield into a productive solar and storage site, we’re expanding access to renewable energy, strengthening the local grid, and putting otherwise unusable land back to work.”
The Acton project is expected to deliver long-term environmental and community benefits by repurposing contaminated land, preserving open space, and creating nearly 40 local jobs during construction.
The community solar model paired with battery storage will enhance grid resilience and generate new tax revenue for the town, supporting Massachusetts’ SMART and Clean Peak Standard programmes.
“Brownfield redevelopment is a powerful way to expand clean energy access while addressing the legacy of industrial contamination,” said Graeme Dutkowsky of Syncarpha Capital.
“This project demonstrates how … building brownfield solar projects can turn an underutilised site into a long-term source of reliable power and local economic value.”

As the UK solar and storage sector gathers momentum, Solar & Storage Live 2025 set the stage for conversations about innovation, infrastructure, and growth.
Among the exhibitors was Aaron Sallows, Divisional Director for sister companies Maintech Power and Dunamis, who shared insights into how the two firms are shaping the future of large-scale solar and storage.
From navigating the bottlenecks of grid connection approvals to tackling harmful SF6 in high-voltage switchgear, Aaron highlights the challenges and opportunities facing the sector.
What are the roles of Maintech Power and Dunamis in the solar-storage industry, and how do the two entities complement each other?
Aaron: Dunamis focuses as an ICP – an independent connection provider – up to 132kV, specialising in design, build and project management, with a particular focus and specialism in battery storage and solar PV. Both gridscale independent and co-located projects.
Maintech Power, the sister company to Dunamis, essentially has many of the boots-on-the-ground teams operating as high-voltage and low-voltage electrical contractors.
We complement each other very well: Dunamis would step in as the ICP contractor, particularly on larger projects, fulfilling the ICP design and build scope requirements and sometimes moving into the balance-of-plant electrical side, depending on the client’s contracting.
Maintech Power would then come in, boots-on-the-ground, to carry out the installation, working alongside Dunamis as a partner. We also sometimes carry that through into the warranty periods post-energisation.
With the growth in solar farms, wind farms, and BESS, what technological innovations or improvements in infrastructure are you most excited about?
Aaron: Personally, I’m excited about moving away from reliance on high-voltage switchgear containing SF6. SF6 is a hugely harmful greenhouse gas, and from my own experience with switchgear leaks, it has a massive detrimental effect on the environment.
Moving away from that – especially in low-carbon renewable technologies – really boosts the benefits of renewable energy from grid-scale solar PV and from BESS as well.
What are your views on the current UK policy and regulatory landscape for large-scale solar-storage? Are there areas that need reform?
Aaron: Without commenting on any specific policies or regulations, I think – as most people in the industry would agree – getting grid connections approved faster would help stimulate the industry.
That would mean more projects being built, and more grid-scale renewable energy and battery storage coming onto the networks.
I also think there’s a huge need for investment to upgrade infrastructure to handle the increased capacity required for these projects. Without that, we risk bottlenecking the industry and slowing delivery.
Where do you see the biggest growth opportunities for Maintech Power and Dunamis over the next three to five years?
Aaron: The biggest opportunities are in transmission projects at 275 kV and 400 kV. There’s huge interest there, but also a big shortage of skills to deliver those projects.
In the next three to five years, we want to explore this area and look at how we can deliver the 300–400 MW projects currently coming through.
What are you hoping to showcase at Solar & Storage Live this year?
Aaron: This year we have a joint stand, showcasing the strength and synergies of Dunamis and Maintech Power.
We’re two side-by-side businesses with a good reputation in the industry, but we don’t usually shout about it too much. A big part of being here is to network and raise brand awareness among attendees.
We also want to showcase our skills by bringing engineers and technical expertise to the show – talking in depth with people about their requirements, helping them feed into tender processes and procurement, and ultimately generating more work.
So far, we’ve had a good mix of people at the stand – suppliers and project opportunities at different stages, from early investment through to more advanced development. It’s been a really positive experience.

Power systems in Central Europe are emerging as key players in the global energy transition through the rapid expansion of solar farms and locally made BESS.
A report by Ember was used by Reuters to analyse the findings.
Since 2022, countries including Austria, Hungary, Romania and Poland have sharply increased the share of electricity generated from solar farms to strengthen domestic energy supplies. This rise has driven fossil-fuel generation to record lows in 2025.
Solar growth has been matched by widespread BESS deployment, with many systems built locally and supported by job-protection policies. Together, these technologies are helping the region move away from legacy fossil-fuel infrastructure and towards cleaner, more resilient power systems.
Austria and Hungary lead this shift. Austria, once reliant on Russia for around 90 % of its gas, has drastically reduced Russian imports and now sources most of its gas from Slovakia. Hungary still purchases Russian oil and gas, but has lowered its gas-fired electricity from over 25 % before 2022 to below 20%.
In 2025, Austria generated about 17 % of its electricity from solar and 10 % from fossil fuels, compared with 6% and 19% in 2022. Hungary’s solar share has climbed to roughly 33%, with fossil generation down to 22%, from 14 % and 35 % respectively two years earlier.
Romania, Poland, Slovakia, and the Czech Republic have also expanded solar generation while reducing fossil-fuel use. Cumulative solar capacity across the five nations has risen by roughly 460 % since 2019, from 8 GW to more than 45 GW in 2024 – well above Europe’s 145 % average increase.
Battery storage is also accelerating. Between 2022 and 2025, Austria, Hungary and Romania boosted BESS capacity by about 472 %.
Project data indicates regional capacity could grow more than tenfold by 2030, reinforcing Central Europe’s role as a growing force in the global shift from fossil fuels.

With over a decade of experience in the UK’s energy industry, Mark Duxbury, UK Country Director of BESS and EMS Solutions at iwell, brings a deep understanding of how smart energy systems can accelerate the transition to a decentralised grid.
In this interview, he discusses why now is the right time for iwell’s UK launch, the critical role of battery storage and smart energy management in the clean energy transition, and how the company’s innovation is setting new standards for energy resilience.
iwell has established itself across the Netherlands, Germany, and Belgium before expanding into the UK. What made now the right time to launch here?
The UK energy market is in transition, moving from a centralised to a decentralised model. The inclusion of BESS & EMS is essential for this to happen effectively.
The archaic infrastructure of the National Grid means having to think outside the box when making changes to a site’s energy requirements – coupled with very high and volatile energy prices, this gives the ideal landscape for iwell’s solutions.
With growing confidence in UK cleantech, what role do you see for battery storage and smart energy management in building a more resilient, renewables-based grid?
It’s a crucial role. The energy transition has only just really begun, with decades of future progress needed to ensure the UK’s infrastructure can cope with the electrification of assets of all kinds.
How does iwell’s in-house energy management system give you an advantage in improving energy security, cost management, and renewable integration for businesses?
With over 300 projects now installed, we have refined and honed our EMS, using customer feedback to tailor the system to be able to maximise its effectiveness.
Having the in-house capabilities to make these improvements, rather than looking to a third-party provider to create the change, alongside all of their other clients’ requests, we have been able to accelerate our EMS to the forefront of what is possible.
As an exhibitor at Solar & Storage Live Birmingham, what feedback did you receive, and what key trends or concerns did UK stakeholders raise?
Combining BESS and EMS as a fully integrated solution, delivered by one in-house team, really sets iwell apart from the competition. Our EMS capabilities were very well received, with many follow-up conversations now underway with potential partners.
Looking ahead, what opportunities and challenges do you expect iwell to encounter as you grow your UK presence?
A partnership approach will be key to our growth and success. BESS & EMS are complex solutions that require considered modelling before installation, as well as a strong and reliable partner to manage the assets and optimise their performance.
At iwell we cover the full process, from design and modelling, through installation and then onto operation of the BESS & EMS. This gives our clients peace of mind that their site will continue to operate successfully, but in a more optimised way.

Press Release
Rondo Energy has started commercial operation of the world’s largest industrial heat battery. A 100MWh Rondo Heat Battery (RHB) has entered daily automatic operation, powered exclusively by an on-site PV solar array and delivering continuous high-pressure industrial heat and steam to a fuel production facility in California.
The unit sets new records for the industrial heat battery industry in capacity, round-trip efficiency, and power supply. This 100MWh unit delivers a volume of heat equivalent to 10,000 home heating systems.
During the day, off-grid solar PV charges the heat battery, and the RHB delivers heat 24 hours a day.
After 10 weeks of operation, the project has achieved all milestones for daily automatic operation, performance, efficiency, and reliability, proving out Rondo’s unique design, which boasts storage temperatures over 1000°C and round-trip efficiency above 97%.
“The Rondo Heat Battery is now proven at industrial scale,” said Eric Trusiewicz, CEO of Rondo Energy. “We are already developing and operating heat batteries across four continents and five industries. Our customers are improving their competitiveness and slashing their carbon emissions at the same time.”
This Rondo Heat Battery is directly delivering steam alongside gas-fired boilers without changes to the facility. This project was delivered with zero lost-time injuries and is fully meeting all customer contract specifications.
By replacing gas consumption with the fixed cost of on-site solar power, the project reduces energy cost volatility, as well as reducing regulatory and carbon market exposure. The lower carbon intensity of the customer’s fuel products strengthens competitiveness in low-carbon markets.
Decarbonising industry at scale
Industrial heat makes up 25% of global final energy use, and industries from chemicals to cement rely on high-temperature heat. Rondo’s technology provides a simple and safe way for manufacturers to reduce costs and slash scope 1 emissions today.
Unlike heat pumps or electric boilers that need constant power, the Rondo Heat Battery charges using only the six lowest-cost hours of electricity per day – whether from off-grid solar or from the grid. Intermittent and low-cost hours of electricity are becoming available in electricity systems around the world, thanks to the deployment of solar & wind.
“The commercialisation of the heat battery represents yet another global inflection point for solar & wind power, said Andy Lubershane, Partner at Energy Impact Partners.
“Just as electric vehicles opened up the transport market to renewable electricity, heat batteries will open up an even larger new market, industrial heat, which accounts for roughly a quarter of global energy consumption. We’re thrilled that Rondo is leading the way.”
Simple, proven, safe
The Rondo Heat Battery’s storage medium uses only brick and wire – abundant, proven materials that can’t catch fire, explode, or cause toxic leaks.
Heat batteries replace or drop in alongside industry-standard boilers and seamlessly integrate into existing steam flanges, delivering steam at any conditions at 100+ bar (1450+ PSI). Because it produces no emissions, the Rondo Heat Battery requires no air permits, easing deployment.
Global scale, ready now
Rondo is already developing and operating projects across North America, Europe, Asia, and Australia, with deployments underway for chemicals, biofuels, food & beverage, and cement. The company’s technology scales quickly, requiring no scarce minerals and using only proven industrial components.
With the 100MWh Rondo Heat Battery now online, Rondo is demonstrating the future of industrial heat, power, and cogeneration – renewable, reliable, and cost-competitive.

EirGrid has opened a six-week consultation on its proposed procurement mechanism for Long Duration Energy Storage (LDES), aiming to enable the delivery of up to 500MW of storage assets capable of at least four hours’ continuous import and export by 2030.
The consultation, published on 13 October 2025, follows the Department of Climate, Energy and the Environment’s Electricity Storage Policy Framework (ESPF) and builds on EirGrid’s 2023 Call for Evidence on LDES.
Respondents to that call highlighted both the benefits of storage and the investment barriers created by revenue uncertainty.
EirGrid said LDES could “play an important role in supporting the transition to a highly renewable electricity system and the delivery of Ireland’s Climate Action Plan targets.”
The operator’s proposal is for a technology-neutral mechanism that complements, rather than replaces, existing market arrangements such as the Capacity Remuneration Mechanism and DS3 System Services.
The initial phase would procure a minimum of 201MW of LDES capacity, prioritising connection types that maximise use of existing infrastructure and projects located in areas of high renewable dispatch-down.
“Such assets can help in providing both import and export flexibility to manage renewable variability,” EirGrid stated, “importing when renewable output is high and exporting back to the system when renewable output is lower.”
To encourage investment, EirGrid proposes a two-strand revenue model. Developers would bid a capped “floor price” based on the Levelised Cost of Storage, providing certainty of income.
Above that threshold, revenues would be shared 70:30 between the LDES operator and the Transmission System Operator.
The consultation also outlines an “operational envelope” system to ensure storage actions support, rather than worsen, grid constraints.
Responses are invited via EirGrid’s consultation portal until 17:00 on 24 November 2025, with a recommendations paper to follow for approval by the Commission for Regulation of Utilities. A second consultation will then address detailed contractual arrangements.
“Stakeholder feedback will be vital to shaping the final procurement design,” EirGrid said in its announcement on LinkedIn, encouraging developers, suppliers and network operators to participate.

A new report from energy think tank Ember suggests that electrification powered by homegrown renewable energy – such as solar – could cut the European Union’s reliance on fossil fuel imports in half by 2040.
The study, Shockproof: How Electrification Can Strengthen EU Energy Security, argues that switching to electric technologies across transport, buildings and industry is key to improving energy security and reducing costs.
Currently, 58% of the EU’s primary energy supply comes from imported fossil fuels – a level of dependence far greater than that of China (24%) or India (37%).
Although reliance on Russian gas has decreased since 2022, the bloc now depends heavily on other major suppliers, including the United States, Norway and Qatar. According to the report, this concentration of supply leaves Europe vulnerable to price shocks and political pressure.
During the 2021–2024 energy crisis, the EU spent €1.8tn on fossil fuel imports – €930bn more than it would have at pre-crisis prices. In contrast, the report notes that electrification, driven by local wind and solar generation, could provide a more stable and affordable alternative.
The power sector already shows progress: only 19% of EU electricity generation relies on imported fossil fuels, compared with 88% in transport. Electric vehicles and heat pumps are helping to displace oil and gas imports.
Denmark’s EV fleet, for instance, reduced oil use by 11% in 2024, while Dutch heat pumps offset 10% of residential gas demand.
Study author and Senior Energy Analyst for Ember, Dr Chris Rosslowe, commented:
“Imported fossil fuels are no basis for a secure and affordable energy system – something Europe has learned the hard way. Homegrown energy sources, such as wind and solar, take on more strategic value in a world faced by frequent crises.
“The full potential of Europe’s homegrown power supply is being wasted by a lack of urgency to electrify. Unblocking electrification is the game changing move that can shield the continent from over-reliance on volatile fossil fuel suppliers.”
Despite some gains, just over one-fifth of EU energy demand is currently electrified. The report finds that two-thirds of remaining energy use could be converted using mature technologies, particularly in road transport and heating.
Ember’s policy recommendations include reducing electricity taxes, maintaining the 2035 combustion engine ban, and prioritising grid expansion to accommodate higher electrification.
The report concludes that “unblocking electrification” is Europe’s most effective route to energy independence, cost stability and decarbonisation.

The Trump administration has announced the cancellation of $7.6bn in grants for clean energy projects across 16 states.
The funding supported more than 200 initiatives, including battery plants, solar farms, hydrogen projects, electric grid upgrades, and carbon capture efforts.
The decision was disclosed on Wednesday in a post by White House budget director Russell Vought, who said: “Nearly $8 billion in Green New Scam funding to fuel the Left’s climate agenda is being cancelled.”
The move comes amid an ongoing standoff between President Donald Trump and congressional Democrats over the federal government shutdown.
Cancelled projects
According to the Department of Energy (DOE), 223 projects were cancelled following a review that concluded they did not sufficiently advance US energy needs or were not financially sustainable.
The department stated the grants came from the Office of Clean Energy Demonstrations, the Office of Energy Efficiency and Renewable Energy, and other divisions.
One of the most significant cancellations involves $1.2bn allocated to California’s planned hydrogen hub. Governor Gavin Newsom’s office said the hub had attracted $10bn in private investment and warned that cutting the project could endanger over 200,000 jobs.
“Clean hydrogen deserves to be part of California’s energy future – creating hundreds of thousands of new jobs and saving billions in health costs,” Newsom said.
Senator Alex Padilla of California called the cancellation “vindictive, shortsighted and proof this administration is not serious about American energy dominance.”
Environmental groups expressed concern over the cuts. Jackie Wong, senior vice president at the Natural Resources Defence Council, said: “This is yet another blow by the Trump administration against innovative technology, jobs and the clean energy needed to meet skyrocketing demand.”
The states affected include California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New Mexico, New York, Oregon, Vermont and Washington.
Previous blows to solar
The news comes over a month since the administration’s August announcement that eligibility rules for clean energy tax credits were being tightened, threatening the country’s upcoming renewable projects. Solar, in particular, was highlighted.
August also saw the cancellation of the $7bn Solar For All programme, which was set to provide easier access to solar power for over 900,000 low-income households.
These targeted blows to the solar – and wider renewable energy – sector are part of a policy shift heralded by the signing of Executive Order 14315, Ending Market Distorting Subsidies for Unreliable, Foreign-Controlled Energy Sources, and the implementation of the One Big Beautiful Bill Act.
The motivation behind this shift is to re-prioritise fossil fuels, according to the US Department of the Interior.

A subsidiary of oil and gas company Reservoir Link has signed an agreement to jointly develop Malaysia’s first dispatchable solar PV plant.
Founder Group Limited, trading as Founder Energy, announced on 26 September that it had signed a head of agreement with Planet QEOS, an agricultural technology and energy group.
The deal will see a consortium led by Founder and Planet QEOS deliver a 310MWp ground-mounted solar PV plant in Baram, northern Sarawak, paired with a 620MWh battery energy storage system (BESS).
The project, named the Baram DeepTech Energy Program, is estimated to be worth RM1.16bn
According to earlier reports from Planet QEOS, partners in the programme also include Malaysian renewable energy firms EFS Energy and ES Sunlogy, along with China State Construction Engineering Corporation (CSCEC) and Chinese renewables provider Hopewind.
Sarawak deputy minister Datuk Gerawat Gala told The Star in August that the project would bring “round-the-clock renewable power to Baram…unlocking the full potential of the Baram hinterland for sustainable growth with improved connectivity, modern infrastructure, new industries, and skilled employment opportunities.”
The consortium will now seek regulatory approvals, financial close and definitive agreements, including power purchase contracts. Plans also include the development of a 200MW Tier-4 Green Data Centre Park in Baram, with Tier-4 being the highest reliability ranking for data centres.
Malaysia has been relatively slow in adopting large-scale storage, partly due to its stable peninsular electricity grid and natural gas resources.
However, renewable energy growth – needed to meet the country’s 2050 net zero goal – along with rising demand from data centres, is expected to increase the role of BESS.

The United States added 5.6GW of battery energy storage from April to June, marking a record quarter, according to the American Clean Power Association (ACP) and Wood Mackenzie.
Utility-scale projects led with 4.9GW installed, a 62% year-on-year increase. The ACP said this is enough to power 3.7m US homes during average peak-demand hours. California, Texas, and Arizona each added more than 1GW, while Wood Mackenzie forecast Florida and Georgia as upcoming growth markets.
Georgia Power, for instance, recently issued a request for proposals for 500MW of grid-scale storage.
Growth may face challenges, said Allison Weis, global head of storage at Wood Mackenzie. “After 2025, utility-scale storage projects must comply with new, stringent battery sourcing requirements to receive the ITC [investment tax credit]. While domestic cell supply is ramping up, supply chain shortages are possible although developers are continuing to consider supply from China to fill in any gaps,” she said.
Weis added: “A rush to start construction under the more-certain near-term regulatory framework uplifts the near-term forecast. Projects that have not met certain milestones by the end of 2025 are at risk of exposure to changing regulations. There is additional downside risk if further permitting delays threaten solar and storage projects.”
The residential market also grew, adding 608MW in Q2, a 132% year-on-year rise. California, Arizona, and Illinois led installations, driven by higher attachment rates and larger-capacity systems.
According to EnergySage, California topped major markets with 79% of quoted projects including batteries, followed by Texas (61%) and Arizona (47%).
“Residential storage is expected to outpace solar due to stronger policy resilience, high attachment rates in key markets like California and Puerto Rico, and continued ITC access through third-party ownership,” said Allison Feeney, research analyst at Wood Mackenzie.
Community, commercial, and industrial storage added 38MW in Q2, up 11%. US storage is forecast to reach 87.8GW by 2029.
