A first-of-its-kind effort for the energy sector

The Space Frontier Foundation is partnering with Experience POWER and Data Center POWER eXchange to add a critically important dimension to the energy industry's conversation about its future. This is a first-of-its-kind effort to bring the Space Solar Power (SSP) conversation directly to utility and energy sector decision-makers — in a sustained, technically grounded half-day program.

The program has three core objectives:

01

Introduce Space Solar Power to power sector decision-makers in a practical, technically grounded way — not as a distant science project, but as a credible planning horizon item.

02

Translate SSP into the frameworks energy leaders already use: levelized costs, capacity factor, transmission integration, regulatory pathways — so they leave with a basis for action.

03

Connect energy system providers to SSP resources and build a sustained support network for early movers who want to begin exploring SSP in their planning and procurement processes.

This symposium is intended to serve as an inflection point — the start of direct, sustained engagement between the Space Solar Power and energy communities, not a one-time conversation.

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.

No additional fee to attend

The Space Solar Power Symposium is included at no extra cost when you register to attend Experience POWER and/or Data Center POWER eXchange.

September 28 – October 1, 2026  ·  Omni Shoreham, Washington, D.C.

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).

Time (AM, ET) Session
8:00 am Keynote & Debate Turn On Space Solar Power

The power sector is entering an era of rapidly rising electricity demand, constrained transmission, and an urgent need for new sources of firm, carbon-free generation.

Keynote: Why Space Belongs in this Energy Room

The opening keynote explains why space solar power should now enter the planning horizon of utilities, data center operators, investors, and energy policymakers — and what this symposium aims to accomplish.

What Space Solar Power Is

A brief overview introduces the technology and the impact of a Space Solar Power future, establishing a common foundation for the discussions that follow.

Does the Case for Space Solar Power Hold Up?

A rigorous debate, argued on both sides through the frameworks energy planners and investors already apply: cost, capacity value, system reliability, financing, transmission integration, and technology risk. One side argues the case holds; the other argues the money is better spent on terrestrial paths. Neither side is a straw man.

Company Spotlights

Five companies share their approach — a rapid view of the different architectures, business models, and near-term applications emerging across the industry.

Key takeaway: What assumptions must hold for Space Solar Power to become competitive — and what evidence should utilities, investors, and policymakers require before acting?

Speakers: Mark Menezes, Sean Mahoney, Darko Filipi, John Bucknell, Vincent Handley, Daniel Kammen, Harry Atwater
9:00 am Panel Grounding Space Solar Power Compelling Advantage for Hyperscale Computing

As AI drives unprecedented demand for reliable electricity, hyperscalers are investing billions in new nuclear, geothermal, and other firm energy resources. This session explores where space solar power could fit — powering terrestrial data centers, enabling orbital computing, or creating entirely new energy architectures that combine both.

Milestones for Future AI Infrastructure

Space solar companies, hyperscalers, and utility leaders discuss where Space Solar Power could create unique value, what performance and economics operators would require, and the technical and commercial hurdles that must be overcome before adoption becomes realistic.

Key takeaway: Where can space solar power provide a compelling advantage over conventional energy solutions for hyperscale computing, and what milestones would make it a serious option for future AI infrastructure?

Speakers: TBD
10:00 am Panel Capturing Space Solar Power Geopolitical Lens & Policy Activities and Actions

Space Solar Power is not only an energy technology; it could become strategic infrastructure influencing industrial capacity, energy security, international standards, and economic competitiveness. This session examines how the United States and other nations are approaching Space Solar Power, which regulatory and governance frameworks already apply, where critical gaps remain, and how government and industry can move together without slowing innovation.

Key takeaway: The countries that establish early capabilities, standards, supply chains, and commercial experience may shape the future market for energy delivered from space.

Speakers: Peter Garretson, Karen Jones, Michelle Hanlon
11:00 am Working Session Plug in Space Solar Power
  • Take this session into your organization
  • Steps to integrate into planning
  • Things space needs to know
  • Worth considering

After learning about the potential, the challenges, the opportunity, and the threats, what do you need to continue considering Space Solar Power? An open, interactive working session that turns the morning's discussion into practical next steps. Participants and speakers will identify priority questions, potential partnerships, pilot opportunities, research needs, and actions that utilities, companies, investors, and public agencies can begin pursuing now.

Key takeaway: Go beyond a general expression of interest — establish the relationships and follow-on activities needed to carry the conversation beyond the symposium.

Speakers: Sean Mahoney, Darko Filipi, John Bucknell, Vincent Handley, Daniel Kammen, Harry Atwater

Recent milestones accelerating SSP

Despite rapid global progress, most energy professionals have not yet encountered Space Solar Power as a credible near-term energy option. That gap is closing fast.

DARPA, 2025 — Beamed over 800 W of power via laser across 8.6 km for 30 seconds, setting new distance and duration world records for terrestrial wireless power transmission.

U.S. Air Force Research Laboratory, 2025–26 — Preparing end-to-end in-orbit microwave beaming demonstrations.

Japan, 2026 — Set to test beaming 1 kW of solar energy from a satellite in low Earth orbit to Earth via microwaves.

China Academy of Space Technology — Advancing large-scale wireless power transmission and planning orbital tests in 2028, with first MW-scale SSP plants targeted in 2030.

Caltech SSPD-1 mission, 2023 — Successfully tested lightweight structures, solar cells, and microwave transmitters in orbit, beaming power wirelessly in space.

U.S. and UK startups — Backed by over $100M including Breakthrough Energy, targeting in-orbit solar power demonstrations by 2028.

High-efficiency space-grade solar panels and reusable heavy launch vehicles are now maturing simultaneously — creating an enabling convergence that did not exist even five years ago. NASA's 2024 analysis suggests SSP could match or surpass terrestrial intermittent renewables on LCOE at $30–80/MWh by 2050. European and UK studies estimate comparable competitiveness with dispatchable renewables at €88–156/MWh.

Space Frontier Foundation

Space Frontier Foundation Logo

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.

The Foundation 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 — in the room where decisions are made.
