Exowatt Secures $50 Million To Scale Solar Power

Exowatt, a renewable- energy technology company backed by Sam Altman, has secured an  fresh$ 50 million in backing to expand manufacturing and accelerate deployment of its dispatchable solar systems across the United States. The  rearmost investment round brings the company’s total fundraising to$ 140 million in under two times,  pressing the growing urgency among data- center drivers, artificial  guests, and state agencies to  land  dependable, low- carbon energy as electricity demand surges civil.

The backing comes at a  vital moment for the U.S. power sector. Electricity consumption, driven heavily by artificial intelligence,  pall computing and electrification, is rising  briskly than at any point in the last two decades. Major technology companies are constructing new data- center clusters across several  countries, reshaping  cargo  vaticinations and forcing energy itineraries to  review timelines for grid upgrades. Amid this  terrain,  results able of delivering  establishment, flexible energy close to consumption  spots are attracting significant private and public interest.

Exowatt’s core immolation, known as the P3 system, captures solar energy and stores it as heat, which can  also be converted into electricity when  needed. This allows drivers to draw on solar power indeed during evening peaks or late hours. The system’s modular design is  finagled for deployment coming to or near data- center premises , reducing dependence on large- scale transmission  structure and lengthy connection  ranges. By producing  establishment, dispatchable power close to  cargo, the company aims to support AI clusters and artificial  installations that bear  nonstop, stable energy  inventories.

According to Exowatt CEO Hannan Happi, the company is seeing  unknown  marketable demand. He emphasized that Exowatt is working through a substantial backlog of  client interest across multiple sectors. The  marketable channel, he said, includes a “ demand backlog exceeding 90 GWh, ” stretching across data- center drivers, energy  inventors and  fresh artificial buyers. Happi noted that the new capital will support scaling U.S. manufacturing and help the company continue  publicizing  guests and  mates in the coming months.

The backing round was led by MVP gambles and 8090 diligence, both of which have been  adding  their exposure to energy technologies  acclimatized to AI and digital-  structure  requests. This round extends Exowatt’s  former Series A  rise of$ 70 million in April 2025, led by Felicis. Several technology and climate-  concentrated investors — including DeepWork Capital, Dragon Global, New Atlas Capital, BAM, Overmatch, StepStone, Atomic and Bay Bridge gambles — also  shared. Exowatt’s  before$ 20 million seed round featured  benefactions from Sam Altman and environmental advocate Leonardo DiCaprio.

Investors view near-  cargo clean power as a strategic precedence. Long timelines for  erecting new high- voltage transmission lines have  urged  inventors and  serviceability to explore  druthers

that can be sited  snappily within artificial zones or  conterminous to large premises . Andre de Baubigny, Managing Director of MVP gambles, noted that AI- driven electricity demand wo n't  stay formulti-year transmission  systems. He described Exowatt’s technology as an American- made  result able of bringing  establishment, clean power directly to load centers.

Rayyan Islam,Co-Founder and General Partner at 8090 diligence, said the company has been tracking Exowatt’s progress and sees its  instigation aligning with the  requirements of domestic manufacturing and arising AI  capitals. He added that Exowatt’s capability to gauge   product and finance deployments positions it to support some of the  swift- growing energy  druggies in the country.

State-  position interest is also expanding as governments seek to attract data- center development while managing grid strain and meeting climate commitments. Florida- grounded investors, for  illustration,  stressed the  part of  rapid-fire-clean- energy deployment in enhancing indigenous competitiveness. officers involved with the Florida Opportunity Fund refocused out that  dependable and low- carbon energy capacity is  getting a central factor in  profitable development strategies in the AI  period.

As  further  countries  contend for data- center investments, they face challenges associated with increased  cargo, including pressure on distribution networks, implicit reliance on peaker  shops, and rising compass 2 emigrations for large commercial tenants. Technologies  similar as Exowatt’s dispatchable solar system offer an indispensable pathway that does n't bearmulti-year permitting and construction of new transmission  structure. These systems can be installed on available artificial land or  conterminous to being  installations, helping  inventors meet both  functional and environmental conditions.

For  directors and investors, Exowatt’s  rearmost backing round reflects broader trends reshaping the energy and technology sectors. The rising  decoration on  establishment, clean capacity is pushing companies to explore  results that convert intermittent renewable  coffers into  dependable power. As AI clusters expand, data- center drivers are prioritizing near-  cargo power options that can be  erected  snappily and offer predictable performance. Private capital is decreasingly stepping in to support technologies that fill the gap between growing demand and limited grid expansion.

Exowatt’s progress will serve as an early  index of the scalability of coming- generation solar- plus-  storehouse systems that calculate on thermal  storehouse rather than traditional batteries. The company’s capability to move from demonstration to  rapid-fire  marketable deployment will  impact how  diligence and governments view dispatchable solar as part of broader grid- modernization strategies.

Beyond the U.S., regions in Europe, Asia and the Middle East are also  passing AI- driven  cargo growth and assessing how to add low- carbon capacity without long detainments. Exowatt’s model — modular, flexible, and able of being sited near end-  druggies — glasses the approach  numerous  inventors may consider as they navigate  analogous challenges. The coming times will determine whether  similar systems can meaningfully ease backups and support the accelerating digital  structure  geography.
