The start-up aims to utilise large solar arrays in geosynchronous orbit, approximately 22,000 miles above Earth, where satellites synchronise with the planet’s rotation to harvest sunlight. The breakthrough technology will then use infrared lasers to transmit that power to utility-scale solar farms on Earth, allowing these facilities to send power to the grid nearly around the clock.

Building Up The Concept Called Space Solar Energy

The concept of “Space Solar Energy” is taking shape quite nicely in the United States and will likely lead the next-generation clean energy research and development efforts. Among the players taking the lead in the research and development-related efforts in this arena, we have Overview Energy.

As the start-up plan revealed its use of the world’s solar panels as nighttime collectors of power beaming down from space, it also raised USD 20 million, and part of that has now gone toward an airborne demonstration of the start-up’s power-beaming technology. A light aircraft, in November 2025, transmitted power using a laser to a ground receiver over a distance of five kilometres (three miles).

However, Overview Energy will be up against competitors like renewable energy player Aetherflux, which is also pursuing a laser-based approach. Then there are ventures like Emrod (pioneering commercially viable long-range wireless power transfer technology), Orbital Composites (a venture redefining additive manufacturing with advanced composites and robotic automation), and Virtus Solis (which has reportedly designed the world’s first space-based solar power energy generation system) that are developing their versions of microwave-based power transmission, which sends energy wirelessly using a different portion of the electromagnetic spectrum than Aetherflux and Overview.

Betting Big On Microwaves

Microwaves are less sensitive to clouds and humidity than infrared lasers, while the latter can’t transmit in cloudy weather since the suspended water droplets would absorb much of the energy. However, since microwave-based systems can’t reuse existing solar farms, they would have to build their own ground stations.

Also, the ground receivers need to be smaller in shape so that they can keep the costs down. In that case, the energy beams need to be tighter and more powerful to make sure they get caught by the receivers efficiently, without causing collateral damage to birds and aircraft.

While renewable industry players are working to address these challenges, Overview Energy has pitched the reuse of solar farms to mitigate some of those concerns. However, the real deal will be to convince people that energy beams from space are safe and won’t stray off target.

Also, the start-up will have to ensure its laser system is very efficient to prevent a situation where solar energy is converted to infrared light and back again.

The start-up is targeting a 2028 timeline to launch a satellite into low Earth orbit, far below the 36,000 kilometres (22,000 miles) at which it finally intends to operate. The satellite will start sending megawatts’ worth of power from geosynchronous orbit from 2030 onwards.

The innovation will also be facing two more rivals: cheaper grid-scale batteries, which are rewriting the United States’ energy storage rulebook, and nuclear fusion in the long run.

What prevented “space solar energy” from elevating from the concept stage to the commercial one were factors like expensive launches, fragile hardware, and, most importantly, the fact that the technology to beam power safely to Earth wasn’t ready.

However, with the rise of the private space industry, launch costs have dropped more than tenfold, and annual launches have grown massively as well. Mass manufacturing of satellites is now routine. High-efficiency photovoltaics and high-power, high-efficiency lasers have become inexpensive, reliable, and commercially available.

The start-up has set a standard for its action plan of sending megawatts’ worth of power from geosynchronous orbit: transmission must be completely safe for people, wildlife, aircraft, and other satellites, while the whole process should cost less than USD 1 billion, which will make it competitive with its industry rivals.

The start-up also plans to use significantly less land than traditional solar plants with battery storage. The solution has a distributed design, eliminating any single point of failure.

Taking A Pragmatic Path

Overview Energy’s satellites will operate at an altitude of approximately 36,000 kilometres (about 22,000 miles) in geosynchronous orbit, collecting sunlight continuously and transmitting it as low-intensity, invisible infrared light.

Since Overview Energy will be using existing solar projects as its infrared beam receivers, requirements such as new land, construction, and years-long waits for interconnection will be eliminated. The start-up’s satellites will be the first moving power plants, directing energy across regions in seconds and across continents in minutes.

This will lead to a situation where solar projects will be generating revenue during 65%-75% of operational hours, without making their assets sit idle. Utilities will be bypassing congested corridors and drawing on infinite energy reserves above the atmosphere. Households will see lower electricity costs, as satellites will be blunting the peaks that drive price spikes.

Off-takers like data centres will have access to massive energy capacity, which will help them come online in days instead of years.

The business is currently busy solving problems such as sourcing cost-efficient materials, precise tracking, and deployable architecture. The whole operational architecture is being tested and validated from lab to aircraft to orbit. Each phase is demonstrating the same core technology that will operate in space, focusing on real-world constraints, while helping the start-up inch toward its cost targets.

Airborne Demo Bringing The Concept To Reality

In November 2025, the start-up achieved a world first in power beaming, as it transmitted power from a moving aeroplane to solar panels on the ground, covering a distance of more than 5,000 metres in the process.

Overview Energy’s team installed laser and optical systems on a Cessna Caravan and flew at an altitude of over 5,000 m (16,500 ft). On the ground, it installed a receiver of standard solar panels, the same kind used in utility-scale projects or homes.

As the aircraft flew overhead, the system identified the receiver, locked onto it, and delivered power through an eye-safe beam. The panels convert that light into electricity in the same way they convert sunlight.

The whole experiment validated the performance of Overview Energy’s core technical pieces that will realise the concept of “Space Solar Energy.” The proof-of-concept phase has also been completed with the airborne technology demonstration. It will now be followed by a pilot low Earth orbit (LEO) mission in 2028 that will demonstrate the full system’s performance in space. The final step will be the Overview Energy’s geosynchronous orbit (GEO) satellites taking over the proceedings in 2029–2030, where they will see the sun 99% of the time.

Recently, International Finance recognised TPI as the “Most Innovative Diverse Energy Business Company – Thailand – 2025.” The company follows a simple business philosophy: T-echnology, P-roduct, and I-nnovation, and this rule has been codified into the company’s efforts.

TPIPP has broadened its operational portfolio, extending beyond waste-to-energy (WTE) fuelled principally by municipal solid waste (MSW) to utilities (oil/NGV petrol stations/EV charging stations), solar farms and roofs, and Alternative Fuel Resources (AFR) based on municipal waste.

Power has become TPIPP’s largest revenue-generating division (c.90%). The energy produced here runs on highly diversified fuel, with most of it in the form of renewables, such as recycled waste heat (WH) captured from the cement plant of the parent company TPI Polene, WTE using municipal solid waste, and solar farms and roofs.

“After multiple years of experimentation and fine-tuning of processes, our WTE-MSW power plants have arrived at a highly profitable cost curve. The current focus of our technical and engineering ingenuity is on the conversion of our 150MW coal-fired power plant into 100% MSW. Once completed, it will be the first conversion of its kind and scale in Southeast Asia. By 2026, TPIPP will be 100% fossil-free and will expand its pool of carbon-related merits from the current level of 2.5 million tCO2eq T-VER certified credits and 3.1 million Renewable Energy Certificates (RECs),” the venture told International Finance.

The conversion of the 220MW coal-fired power plant is ongoing. The project has been divided into six phases, and TPIPP is now at the tail end of phase six, with a 2025-end targeted completion timeline. TPIPP aims to make its power generation completely coal-free by 2026.

“So far, the modification programme is going smoothly. We are confident that we will be successful, and this would classify TPIPP as avant-garde in the conversion of coal-fired power plants to MSW. It would be a feat, the first of its kind. The know-how and learning accumulated from the experience can make TPIPP a resource for other power generators currently operating coal-fired power plants in the region, especially in Southeast Asia,” TPIPP noted further.

TPIPP, which believes that coal-fired power plants need not become stranded assets amidst the global push towards ESG (environmental, social, and governance) and sustainability, continued, “Our solar power farms and roofs are cost-minimising programmes and also assist TPIPL in its strategic move towards Green Cement & Building Material Products. With solar power, TPIPL’s offtake from the national grid will be reduced, enhancing its green credentials.”

The issue of battery storage for the solar farms has been installed. This installation extends the solar power supply into the night, further reducing offtake from the main grid, apart from enhancing the green credentials of the cement and building materials produced. TPIPP, in April 2025, entered into a agreement with Jinko ESS (a globally leading PV module manufacturer and energy storage system integrator) to set up a 25MWh energy storage plant.

“Our Utilities division mainly supports TPIPL’s logistics and distribution capabilities. TPIPL is electrifying its logistics and distribution vehicles, and TPIPP’s petrol/NGV and EV charging stations are strategically located along the regular routes of TPIPL’s vehicles,” the business remarked.

Alternative fuel resources have become a natural extension of TPIPL’s MSW operations. One of the many moves TPIPL is pursuing to produce “Green Cement” and “Building Materials Products” is to substitute coal in its clinker production with MSW.

“These further drive increases in MSW. Currently, TPIPP processes close to 10,000 tons per day of raw waste. When the various programmes are completed, the daily drawdown of waste will rise to 14,000 tons per day. With our power plants and AFRs, TPIPP will be a significant contributor to addressing the ever-growing problem of household waste. This is another pathway where we contribute to the betterment of society,” the company said, continuing, “Because our daily intake of municipal waste is high and our power plants are in a single location, we can support the livelihoods of residents in many communities. Where landfills are becoming an issue, we also assist the local government by supporting the efforts of its indigents to gather garbage from which calorific values can be extracted. We now have documented cases showing the benefits we can bring to communities.”

TPIPP has also started the rollout of its two WTE-MSW capacities (c.10MW). One will be in Songkhla (south), with Mukdahan (northeast) being the other. Each project will use the municipal waste produced in the area, about 500 tons per day, thus eliminating the need to allocate space for a landfill. These projects will be completed in 2025 and 2026, respectively.

The company is testing six bifacial panels from three manufacturers, two trackers and string inverters. Last year, it announced a 1 GW renewables development plan for Chile.

Also, the company has purchased a special vehicle with a 48-MW wind farm and a 34.4-MW hydropower plant in the country. It is reported that the company has already started operating the assets.

Also, Engie is expecting the assets to benefit its net income of $3 million for the second half of 2020, media reports said. The wind farm Monte Redondo comprising 24 turbines  is located in the Coquimbo region, while Laja hydropower plant in the Biobio region. The latter commenced operations in 2015.

More recently, Engie announced that it will appoint a new CEO in September as it transitions toward renewable energy in the coming months. Engie Chairman Jean-Pierre Clamadieu, told a local media, “We want the CEO job to be filled by year-end, which implies choosing the right candidate in September.”

The company is also working with Huisman Geo, EBN and TNO to explore a new drilling technique, media reports said. However, the exact location for the activity will be announced in 2021.
