Integrating a Proprietary Technology with Conventional
Components to Deliver Highly Reliable, Renewable Power
HELIOSTATS Software-controlled field of
mirrors concentrate sunlight
on a boiler mounted on a
central tower.
OPTIMIZATION / CONTROL
SOFTWARE Proprietary optimization software and Solar Field
Integrated Control System manage heliostat
positioning to optimize concentrated sunlight on
the boiler.
STORAGE When integrated, cost-effective thermal energy
storage extends solar electricity production into
later parts of the day after the sun goes down.
AIR-COOLED
CONDENSER Low-impact design, using
over 90% less water than
competing solar thermal
technologies that use
conventional wet-cooling.
AUXILIARY GAS-
FIRED BOILER Allows for hybridization,
increased output and the
enabling of more reliable
electricity production.
TURBINE Steam powers turbine to produce
electricity – then is converted back to
water through an air-cooled condenser.

We combine Alstom’s extensive experience in the field of turnkey power
plants and key power equipment (e.g. steam turbines and solar receiver
steam generator) with BrightSource’s LPT solar thermal technology
Heliostats: Intelligent and Precise
Heliostats individually positioned in field to optimize annual plant output
Account for real time weather, sun location, and wind
Heliostats “communicate” with each other to optimize radiation collection
and solar receiver heat balance
Two flat glass mirrors (2.3m x 3.3m) mounted on a single pylon
equipped with a computer-controlled drive system
System delivers beam accuracy in excess of one mile
Solar Field Integration and Control System (SFINCS)
Algorithmic software determines the optimal position of each heliostat accounting
for the unique conditions of each project site
The SFINCS control system manages distribution of energy across the solar
receiver using real-time heliostat-aiming and closed-loop feedback
On-site weather systems, and visual and infrared cameras provide real-time
feedback into advanced algorithms for solar field management
Proprietary optimization and control software maximizes project performance and
power production efficiencies

production
Hybridization for extended
production

Solar Hybrid Applications for Fossil Baseload Power Plants (1/2)
Solar hybridization allows fossil baseload power plants to reduce fossil fuel
consumption, air pollutants and other regulated emissions.
We offer three unique solar thermal hybrid power plant
configurations for customer specific applications:

PV Output Variability
… Requiring additional flexible generation to maintain reliability
Output Variability Impacts Grid Reliability and Increases Costs …
Wind and PV Have Lower Reliability Due to Poor Alignment With System Peak Demand
Additional resources are needed to meet reliability requirements

Development Commission (energy commission), to the California State Assembly Utilities and Commerce Committee, Informational Hearing, March 29, 2007.
Production output of wind and PV are illustrative. Not drawn to scale with load shape curve.
Integration costs are increasingly being assigned by utilities
to intermittent resources within the selection process
Chart Source: Wiser, Ryan and Bolinger, Mark, Lawrence Berkeley National Laboratory, “2009 Wind Technologies Market Report”, pg 65; and, Navigant Consulting et
al; Large Scale PV Integration Study, Prepared for NV Energy; July 2011 1"Competitive Market Analysis Prepared for BrightSource Energy" (E3, March 2012).
The California Public Utilities Commission Long Term Planning Process methodology applies $7.50/MWh, as a “penalty” for all wind and solar resources in resource ranking and selection.1
According to Energy and
Environmental Economic (E3),
while integration cost estimates
vary by study, there is a
clear upward trend in
integration costs,
per megawatt hour,
as renewables penetration
increases.1
CSP Avoids Real Integration Costs Imposed by Intermittent Resources

Net System Cost is Used by Utilities to Evaluate Cost Competitiveness
Energy storage increases asset utilization and transforms
solar thermal into a high-value, flexible resource
Storage is discharged when most economic to dispatch the power plant
Energy storage enables optimization of
production profile against market prices Production output of PV and CSP are illustrative. Market Price / System Value are representative, not actual, prices.
Integrating Storage Transforms a Solar Thermal Plant into a High-value, Flexible Resource
Capacity value refers to a power plant’s expected available production during peak demand
hours multiplied by forward capacity prices.
Capacity Value = On-Peak Availability Factor % × Plant Capacity (MW) × Capacity Price
Reliable resources, such as solar thermal and natural gas,
have higher capacity value
1On-peak availability factors used for planning from California’s 2010 Long Term Planning Process (LTPP), except Solar Thermal with Storage from Western Wind
and Solar Integration Study, Prepared for NREL by GE Energy, May 2010 and Simple Cycle Natural Gas is a BrightSource management estimate.
Capacity Value Varies According to the Availability of a Resource at System Peak

BrightSource Solar Plant with Thermal Energy Storage
Extends electricity production into later parts of the day and after sundown,
when valued most by utilities
Reduces the cost of renewable power: - Increases a plant’s capacity factor / higher asset utilization
- Offers higher efficiencies than competing solar thermal power plants
Provides utilities with greater operational flexibility to shape production to account
for variable production of other intermittent resources
Offers utilities and grid operators additional operational and market value: - Balancing and shaping capabilities
- Ancillary services to support a reliable grid
CSP with storage
compares
favorably with PV
and wind when
considering grid
system costs
Impact is greater
as non-
dispatchable
renewables exceed
5% of total
