Closer Look at

Utility-Scale Solar Power

BSE Overview

Proven, Environmentally-Responsible Technology:

  • Highest temperature and pressure solar steam

  • Dry-cooling reduces water use

  • Environmentally-friendly design

  • Successful Pilot and Demonstration Projects:

  • SEDC Pilot generating ~100% of modeled energy at ~97% availability; exceeded 6MW design point by ~20%

  • Chevron Demonstration Solar-to-Steam for Enhanced Oil Recovery (EOR) nearly complete (solar field 95% erected, tower erection complete; boiler erection in process, SFINCS control system onsite)

World Class Team:

  • Includes the key senior managers of Luz Int’l., which designed & built over 350 MW of solar thermal plants in the 1980’s

  • Project development team with over 20GW power projects developed, constructed, and managed

  • Robust Commercial Pipeline & Project Dev.:

  • 2.6GWs of signed PPAs with PG&E and SCE

  • Ivanpah ~400MW Electric for PG&E and SCE

    • Bechtel as EPC and Investor

    • Siemens Turbine/Riley Boiler

    • $1.37B DOE loan guarantee

    • ITC cash grant eligible

    • NRG Energy lead project investor

  • Shortlisted for a project in Israel

  • Selected and approved for a project in Crete

Low-impact Design : Fitting the Natural Environment

  • Plant Design:

    • Maximizes retention of existing vegetation, land contours & natural features

    • Solar field does not require concrete foundations, and grading and leveling is extremely limited

  • Mirrors on pylons placed directly in the ground to fit natural contours of area, without need for foundations

  • Vegetation in the solar field will co-exist below the mirrors, trimmed so mirrors can track the sun

  • Soils and vegetation disturbed during construction and operation will be restored

Low Impact Design – Limited Water Use

  • Water Use: Dry-cooling, Conservation & Closed-loop recycling

  • Uses air instead of water to condense steam

  • 95% less water use when compared to CSP using traditional wet-cooling

  • Uses 25 times less water than

  • competing trough technologies

  • Uses less than 100 acre feet per year;

  • equal to 300 homes worth of water

  • Closed-loop steam cycle &

  • conservation measures further reduce usage

  • Efficiency trade-off: Additional costs incurred by using dry-cooling are merited by environmental benefits
