Space Solar Power Symposium
A dedicated half-day program produced by the Space Frontier Foundation —
September 30, 2026, at the Omni Shoreham in Washington, DC.
Panels, keynotes, and an interactive workshop bringing the most credible voices
in Space Solar Power into direct dialogue with utility, grid, and energy industry leaders.
How to attend
The Symposium runs the morning of September 30 as part of Experience POWER (Sept 28–Oct 1). You can register for the half-day only, or as part of the full multi-day conference.

About the program
Why Space Solar Power, why now
Space Solar Power (SSP) collects solar energy in orbit and transmits it wirelessly to Earth via proven microwave or laser techniques. Because satellites receive near-constant sunlight unobstructed by atmosphere or weather, SSP delivers 24/7 uninterrupted, zero-carbon, dispatchable power — independent of weather, seasons, or geography.
For energy professionals, it's best understood in familiar terms:
- Firm clean generation with a capacity factor above 95% — comparable to nuclear, not solar or wind
- Dispatchable power that can be directed to any location on Earth with a receiving rectenna
- No long-duration storage required to achieve 24/7 delivery
- No new high-voltage transmission corridors required to reach underserved or constrained regions
SSP directly addresses the structural problems energy professionals deal with daily: intermittency, grid integration complexity, transmission bottlenecks, and the rising cost and physical limits of long-duration storage. It doesn't incrementally optimize around those constraints — it removes them at the source.
A technology whose time has arrived
Despite rapid global progress, most energy professionals haven't yet encountered Space Solar Power as a credible near-term option. That gap is closing fast:
- DARPA beamed over 800 W via laser across 8.6 km for 30 seconds in 2025 — new world records for distance and duration in wireless power transmission
- The U.S. Air Force Research Laboratory is preparing end-to-end in-orbit microwave beaming demonstrations in 2025–26
- Japan will test beaming 1 kW from a satellite in low Earth orbit to Earth via microwaves in 2026
- China Academy of Space Technology has orbital tests planned for 2028, with first MW-scale SSP plants targeted for 2030
- Caltech's 2023 SSPD-1 mission successfully beamed power wirelessly in space — testing structures, solar cells, and microwave transmitters in orbit
- U.S. and UK startups backed by over $100M — including Breakthrough Energy — are targeting in-orbit demos by 2028
High-efficiency space-grade solar panels and reusable heavy launch vehicles are now maturing simultaneously — an enabling convergence that didn't exist five years ago. NASA's 2024 analysis puts SSP's projected LCOE at $30–80/MWh by 2050. European and UK studies estimate competitiveness with dispatchable renewables at €88–156/MWh.
What this program is designed to do
This is a first-of-its-kind effort to bring the Space Solar Power conversation directly to utility and energy sector decision-makers — in a sustained, technically grounded half-day block, integrated into Experience POWER 2026.
- Introduce SSP to power sector decision-makers in a practical, grounded way — not as a distant science project, but as a credible planning horizon item
- Translate SSP into frameworks energy leaders already use: levelized costs, capacity factor, transmission integration, regulatory pathways — so attendees leave with a basis for action
- Connect energy system providers to SSP resources and build a sustained network for early movers
The Space Frontier Foundation produced the
2025 International Conference on Energy from Space in France — bringing together governments, energy companies, space agencies, startups, and investors. Experience POWER is where that conversation comes to the U.S. energy community, in the room where decisions are made.
Program agenda · Morning of September 30
What's on the schedule
The half-day block runs the morning of Wednesday, September 30, 2026, at the Omni Shoreham Hotel, integrated within the broader Experience POWER and Data Center Power Exchange agenda (September 28 – October 1).
K
Opening keynote: Framing Space Solar Power within future firm power demand
Why firm clean power is the defining challenge of the energy transition — and why SSP belongs in the room.
1
Panel: Technology and timeline — grounded in reality
Where the hardware actually stands: recent demonstrations, near-term milestones, and an honest assessment of proven versus still-ahead.
2
Panel: Economics, grid integration, and deployment
LCOE, capacity factors, transmission integration, and how SSP fits the models energy planners already use.
3
Panel: Policy, regulatory pathways, and governance
The U.S. and international regulatory landscape — what's in place, what's needed, and where government and industry can move together.
4
Panel: The commercial Space Solar Power landscape
Who is building, who is funding, and where the first commercial opportunities are forming.
W
Interactive workshop: Scenario planning and roadmap to sustained engagement
Participants work through real energy system scenarios to identify where SSP fits their planning — and leave with a concrete next step.
K
Closing keynote: Reimagining possibilities with Space Solar Power
What the energy system looks like when SSP is part of the mix — and the opportunity for early movers who act now.
Live demonstrations during breaks between sessions.
Why attend
What you'll take away
Access a new firm power resource
SSP addresses intermittency, grid integration, transmission bottlenecks, and long-duration storage limits — in a single dispatchable resource.
Use the frameworks you already know
Sessions translate SSP into levelized cost, capacity factor, and transmission integration terms — not rocket science.
Connect with the ecosystem
Meet startups, government program leaders, researchers, and energy professionals who are already planning around SSP.
Get ahead of the curve
Early movers who explore SSP and build partnerships now will shape the nation's energy future and secure a lasting edge.

Produced by
Space Frontier Foundation
The Space Frontier Foundation is a U.S.-based 501(c)(3) non-profit dedicated to opening the space frontier to benefit humanity through the power of free enterprise. Outside the space industry, Space Solar Power is undervalued as a potential energy solution. The Foundation listens to the energy community, connects it with SSP innovators, and translates the technology's value in practical terms — to accelerate market arrival.
A proven convening partner
We produced the 2025 International Conference on Energy from Space in France, bringing together governments, energy companies, space agencies, startups, and investors. The event demonstrated strong global momentum and cross-sector demand for SSP engagement. Experience POWER is where that conversation comes to the U.S. energy community.
