Space Power Supply Global Market Report 2025

The space power supply market size has grown strongly in recent years. It will grow from $2.68 billion in 2024 to $2.9 billion in 2025 at a compound annual growth rate (CAGR) of 8.4%. The growth during the historic period can be attributed to increasing investments in low Earth orbit satellites, rising demand for satellite-based communication services, a surge in commercial satellite launches, growing reliance on space-based navigation systems, and an increase in government budgets for space exploration.

The space power supply market size is expected to see strong growth in the next few years. It will grow to $3.96 billion in 2029 at a compound annual growth rate (CAGR) of 8.1%. The growth in the forecast period can be attributed to the increasing deployment of satellite mega-constellations, rising interest in lunar and Mars missions, growth in small satellite launches, increasing demand for continuous power on space stations, and expanding private sector participation in space exploration. Key trends in the forecast period include advancements in high-efficiency solar panels, innovations in long-life battery systems, integration of nuclear power sources in spacecraft, development of hybrid energy storage solutions, and progress in thermoelectric generator applications.

The increasing number of satellite launches is expected to drive growth in the space power supply market going forward. Satellite launches involve deploying artificial satellites into orbit around Earth or other celestial bodies using rockets or launch vehicles for purposes such as communication, navigation, Earth observation, or scientific research. The number of satellite launches has been steadily increasing due to the proliferation of satellite constellations aimed at enhancing global communication, navigation, and Earth observation capabilities. Space power supply is critical for satellite operations, providing reliable energy to run onboard systems, maintain communication, and support payload functionality throughout the mission. For example, in November 2023, the United States International Trade Commission, a US-based federal agency, reported that the number of annual space launches worldwide rose from 186 in 2022 to 197 in 2023. Therefore, the growing number of satellite launches is driving the growth of the space power supply market.

Leading companies in the space power supply market are focusing on developing innovative products, such as space-optimized power supply modules, to deliver compact, high-efficiency, and reliable power solutions for satellites, unmanned aerial systems, and other space platforms, enabling longer mission life and reduced thermal management requirements. A space-optimized power supply module is a compact, highly efficient power conversion unit designed to provide reliable electrical power while minimizing size, weight, and thermal output. For instance, in July 2025, Frontgrade Technologies Inc., a US-based aerospace and defense company, launched the PSM28 Power Supply Module, a space-optimized power supply module. This rugged, compact, high-output solution is designed for SWaP-constrained platforms such as small satellites, unmanned aerial systems, and electronic warfare systems, delivering up to 150W of reliable, regulated voltages with flexible multi-output distribution, real-time telemetry, temperature sensing, and predictive maintenance capabilities, all optimized for seamless integration into modular mission systems under the MAMBA initiative.

In January 2022, Rocket Lab Corporation, a US-based company that manufactures and operates rockets and spacecraft, acquired SolAero Holdings Inc. for $80 million. Through this acquisition, Rocket Lab aims to strengthen its vertical integration by bringing advanced space solar power capabilities in-house, enabling the company to supply critical power solutions for its own spacecraft as well as external customers, while expanding its end-to-end space mission offerings. SolAero Holdings Inc. is a US-based supplier of space solar power products and solutions for satellites and spacecraft.

North America was the largest region in the space power supply market in 2024. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in space power supply report are Asia-Pacific, Western Europe, Eastern Europe, North America, South America, Middle East and Africa.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp hike in U.S. tariffs and the associated trade disputes in spring 2025 are notably impacting the aerospace and defense sector by raising costs for titanium, carbon fiber composites, and avionics materials largely sourced from global suppliers. Defense contractors, locked into fixed-price government contracts, absorb these added costs, while commercial aerospace firms face airline pushback on higher aircraft prices. Delays in component shipments due to customs bottlenecks further disrupt tight production schedules for jets and satellites. The industry is responding by stockpiling critical materials, seeking waivers for defense-related imports, and collaborating with allied nations to diversify supply chain.
