Space Based Green Clean Power

For California Homes, Clean Power From Space

In early December 2009, California Public Utilities Commission approved an ambitious project to beam solar energy from space to generate electricity starting in June 2016.


Under the terms of the contract between Pacific Gas & Electric (PG&E) and Solaren Corporation, PG&E will buy 850 gigawatt hours (GWh) for the first year of the term, and 1,700 GWh per year over the remaining years. The cost of the electricity is competitive with land-based renewable energy sources.

Solaren consists of a number of aerospace engineers, it is a start-up company nearly a decade old with headquarters located in Manhattan Beach and Los Angeles County, California.

The Solaren project will provide baseload power from a space-based technology that collects solar energy as it travels in a geosynchronous orbit and converts the energy into radio frequency (RF) power for transmission to a receiving station located in Fresno County, Ca. The RF power will then be converted to renewable electricity for delivery to the power grid. Generating enough electricity to power tens of thousands of homes.

Solaren’s engineers have designed a relatively lightweight system around a Mylar mirror that’s 1 kilometer (0.62 mile) in diameter to concentrate light onto the solar panels. They have been working with United Launch Alliance (a joint venture of Lockheed Martin and The Boeing Company) to launch four or five heavy-lift rockets containing the solar power systems.

The company plans to run pilot tests before an actual launch. Then once in geosynchronous orbit, a series of SSP (space solar power) pilot plant system tests will validate the satellites, ground receiver station functions and verify performance, safety and key parameters to ensure successful operations.

Will the radio wave transmission technology used to carry energy from space to Earth work? It should, during a four-month experiment in 2008 a former NASA scientist and his team transmitted solar power over a distance of 92 miles between two Hawaiian islands.

A solar energy system in orbit could provide a clean, reliable source of solar power that avoids the interruptions of cloudy days and bad weather on Earth.

You just gotta love California! They are not afraid to look a challenge in the eye and bet on the future with their aggressive renewable energy goals. How bout the rest of you 49 states?

…. as the green future unfolds.

Have you heard of Moneza? It is the next must have in corporate branding and social networking. Give it a try!

    This is one great idea. I think Japanese engineers have worked on such an energy source a few years back. Great idea, simply great!

    Hi Apollo …. yes! the japanese do have a similiar project in the works. I haven’t checked on how they are doing. I was just pleased and a little shocked that the
    California PUC approved this project! ­čśÇ

    Hi Karen … ;D It’s an awe inspiring thing! We are part of history right now… and it’s really cool!

    I own a Fresno drafting and design firm and I stay very plugged into to local news, politics, etc. especially for new infrastructure projects, and this is the first I’ve heard of this. If the receiving station is really going to be located in Fresno, I’m shocked that this is not all over the local Fresno news. Anyone know where I can get more details about this project?

  7. Linda Says:

    Hi John … here’s a link to a PDF between California PUC and PG&E that will help you with names and address’ to hopefully get the info you need. Good luck and thanks for coming by – hope to see you back again.
